Rinnai has unveiled a CIBSE-approved CPD on Seasonal Performance Factors, on the efficacy of Heat Pumps, to a focus group of consultants, systems designers and contractors in London. The CPD started as a ‘White Paper’ presenting an innovation in measuring system performance and providing increased detail into the efficiency of commercial heating and hot water dispersal systems. Rinnai’s Sean Ehlen M Eng was the author of the SPF White Paper, and it is freely available to view HERE

 

Rinna’s focus group was well attended and concentrated on introducing an alternative methodology – Seasonal Performance Factor – to evaluate the efficiency of commercial heating and hot water systems. Rinnai’s Sean Ehlen M Eng hosted the presentation explaining his new approach and then took questions. The peer-led focus group arrived at the conclusion that the Seasonal Performance Factor approach provided customers with greater added transparency towards system performance, cost and expectations.

Rinnai’s ‘White Paper’ report details the potential limitations of manufacturer-issued efficiency measures for Heat pumps, namely COP (Coefficient of performance) and SCOP (Seasonal Coefficient of Performance). Manufacturers often measure heat pump efficiency using Coefficient of Performance (COP), which is the ratio of useful heat energy produced to the electricity consumed at a specific external air temperature and temperature rise required.

Due to the SCOP rating solely measuring the efficiency of the heat pump unit, this may yield a lack of system congruity when considering the entire system. Consequently, relying on this performance measurement alone can affect the overall system expectations and ultimately the expected carbon reductions.

Instead, the Rinnai White paper has adopted the ‘Seasonal Performance Factor.’ This methodology evaluates all energy utilizing components within a commercial hot water system, therefore, measuring the performance of the entire system as opposed to solely the heat pump.

By presenting this White Paper to UK customers, Rinnai aims to provide information that delivers a concise and true account of commercial hot water heating performance using the ‘Seasonal Performance Factor’ methodology.

Rinnai continues to inform the UK market of details that provide an accurate statement of system performance, while considering the effects on operational expenditure, economic investment, and environmental impact.

Rinnai understands the significance of an investment during a time of sensitive economic constraints and rising energy costs. Rinnai aim to share all information that assists the UK customer in decision making that assists the drive to NetZero and is financially efficient.

Rinnai hybrid system provides practical, economic, and technical solution at luxury complex in the city of London

Rinnai Low-GWP 55kW Heat Pump, bespoke thermal stores, Plate Heat Exchangers and 10 cascaded I2HY20 Hydrogen- ready continuous flow water heaters specified at new development in the heart of Farringdon district of London.

On this site Rinnai’s Hybrid H2 array of Low-GWP 55kW heat pump plus bespoke hot water stores, with optimised coil transfer to maximize heat pump performance, have been combined with ten cascaded Hydrogen blends ready (I2HY20 certified) continuous flow water heaters. The systems were delivered in one complete consignment, ready for installation at a new multi-million-pound development in the Farringdon district near the City of London. The expansive complex will comprise of a new luxury hotel, prestigious & contemporary office space plus affordable housing units.

The multi-purpose use of the site meant that only a fit-for-purpose design would satisfy the practicalities and nuances of space, demand and energy usage in ensuring hot water requirements are met and exceeded 24/7.

The site was originally a Victorian-era schoolhouse for poor children. It was a ‘Ragged School’ – the term ‘ragged school’ was used by the London City Mission as early as 1840 to describe the establishment of schools, ‘formed exclusively for children raggedly clothed’. From around 1845 until 1881, the London ‘Ragged’ schools gave rudimentary education to about 300,000 children who were the poorest of the poor – orphans, waifs and strays.

The expansive retro-fit site will pay respect to this heritage with many of the original features retained in the 150+ bedroom luxury hotel, almost 20,000 sq ft of opulent capital city office space and nine new-build affordable residential units. The hotel group already has one other unit in London with two others planned.

Comments Darren Woodward for Rinnai,

’The site is very complex and still has many original features from the Victorian era – meaning that a full and comprehensive site survey with capital expenditure, operational expenditure and carbon modelling was conducted. We paid special attention to the practical requirements of the site which included 150 luxury bedrooms that needed constant hot water on demand, but we also needed to meet the site’s decarbonisation credentials. The overall system design meant that a truly hybrid system employing a heat pump, plate heat exchangers, bespoke thermal stores plus Hydrogen-ready hot water heating units was supplied in one complete consignment.

“We believe that a solution like this is the way forward on the bigger retrofit sites in London and all other UK cities. Once we had the data for capital expenditure, operational expenditure and carbon modelling we were able to demonstrate to the clients a value proposition of a delivered-to-site-in-one-package. This site has proven that Hybrids can create a practical, economic and technical feasible solution whereby all technologies and appliances work efficiently in terms of operational costs and lowering the carbon footprint without impacting overall system performance.

Rinnai’s Chris Goggin explores how wider electrification of the UK domestic & commercial energy mix could influence decarbonisation efforts and customer choices of heating and hot water appliances.

Will Britain’s national electrical grid hold the capability of handling extra demand?

As part of the recent “Powering Up Britain” Govt document, wider electrification was specified as a key strategic aim in decarbonising the UK. Future domestic & commercial & industrial energy will be provided through several ways, one method of decarbonisation will focus on producing sustainably sourced and cheap electricity for UK customers.

There is a series of logical steps if NetZero is to be achieved by 2050. If the UK is going to proceed with decarbonisation through electrification, then providing the electricity for the mass use of electric vehicles will be key. To power an Electric Vehicle (EV) requires the widespread availability of charging points across the UK. There are over 33 million vehicles on the UK’s roads, the majority of which will require electricity.

Can current National Grid capacity cope with increase of electric vehicles AND the demand surge for domestic, commercial and industrial usage facilitated through wider UK electrification?

A BBC article published just recently has revealed that clean energy projects are being put on hold due to a lack of electrical grid capacity. Some renewable energy companies believe this lack of electrical grid capacity could potentially negate the progress of UK NetZero targets.

It has been estimated that the UK requires five times more solar power and four times as much wind generation than what is being presently manufactured. All of which will need to be connected to the national grid. The BBC report estimated that £200 billion of clean energy projects are waiting to be connected with 40% of these projects facing at least a year of further procrastinating.

UK decarbonisation aims are centred on the dispersal of clean and cheap electricity. However, relying on renewables in the short term to completely satisfy national energy supplies is not risk adverse. Renewable power yield relies on weather conditions that seasonally fluctuate.

Although possible, there are still theoretic and technical challenges that require addressing before the UK electric grid can be considered capable of handling both wider national electrification and the inclusion of EV’s on UK roads.

Electricity is generated through various renewable and non-renewable practises such as wind, solar, tidal, nuclear and natural gas. Although UK energy policy makers are keen on reducing and eventually phasing out fossil fuel usage altogether, natural gas has been recognized as a key decarbonising transitional fuel source, as it is used in times of low wind yield to produce electricity (wind being the second highest contributor to UK electrical generation at 25%).

UK policy makers have identified cheap and sustainable electricity as a main contributor to national decarbonisation efforts. As a result, the UK’s electrical capacity grid will have to be expanded. ‘Powering up Britain’ also states that energy independence can be achieved through potentially doubling Britain’s electrical capacity by 2030 whilst ensuring cost effective electrified power.

To provide continuity to UK home market energy supplies, a baseload of power is dispersed to communities throughout the UK. A baseload of power ensures that the minimum requirement of national demand is constantly met. Baseload energy demands are satisfied via energy sources that are cost effective and readily available, such as natural gas.

Dispatchable power are separate sources of energy that are utilized in times of peak demand. Throughout the calendar year the UK power grid will experience times of pressure where it is a necessity to incorporate additional energy to cope with demand and output.

Current capacity of the UK electrical grid stands at 334.2 TWh (terawatt-hour: a unit of energy equal to one trillion watts for one hour). It is estimated that with the inclusion of electric vehicles will create an additional 100TWh demand increase. That, in rounded terms, means an increase of about one third of current levels.

The UK electrical grid is designed to coincide with seasonal and daily peak times of demand. For example, in a seasonal context the demand for electricity is far higher in January then it is in July. Daily electrical demand rhythms are similar – evening demand is far higher than in mid to early afternoon.

Developments in technology, energy efficiency and inclusion of renewables mean that the UK electric grid needs to be positioned to deal with further output demand created by the anticipated but not guaranteed widespread EV adoption across the UK.

Work will also continue to develop V2G (vehicle-to-grid) technology that allows electric car owners to send excess un-used electricity back to the grid when demand is high further creating grid flexibility.

Inter-continental grid connections to countries such as France, the Netherlands, Ireland, Belgium and Norway are connected to the UK through sub-sea cables. This means the UK grid can access power from other nations in times of high demand and system stress, as well as import and export at financially beneficial rates.

The recent “Powering Up Britain” paper stated the UK government’s aim to accelerate delivery of strategic transmission upgrades by at least three years with the specific aim of reducing delivery time in half to UK customers. The Electricity Networks Commissioner will be advising the UK government on how to accelerate grid delivery and will present recommendations to ministers in June.

Rinnai understands the complexity of UK decarbonisation efforts and we are committed to informing UK customers on the detail and impact of current and future energy policy as well as shifts in the energy landscape that could affect customer cost.

Creating a healthier way of living

 

RETRO-FIT PROJECT FUTUREPROOFS BY REPLACING TRADITIONAL STORAGE WITH
HYDROGEN BLENDS READY CONTINUOUS FLOW WATER HEATERS

 

NEW SYSTEM YIELDS

30% REDUCTION IN CARBON EMISSIONS

90% INCREASE IN PLANTROOM SPACE

PROJECTED OPERATIONAL SAVING OF 21%

 

 

Rinnai N Series Hydrogen Blends ready 20% continuous flow water heaters have replaced a direct-fired hot water heating system at a state-owned site in South Wales which needed lower carbon and had a requirement for temperature accurate hot water to minimise any potential Legionella risk.

Six Rinnai N Series 1600i units were installed on a cascade frame to yield almost 6,000 litres of temperature accurate hot water per hour at 50 degrees C. The system included Rinnai UK’s Smart Remote Monitoring System for BMS Integration and common header flue system to streamline installation.

“All works were carried out and completed on time and to the very highest of standards. This state-owned site has a high foot fall through the building and so needs on demand hot water first time, every time,” says Ricky Lewis for Rinnai.

The Rinnai N Series is i2HY20 certified and is a high-performing condensing water heater delivering temperature accurate, limitless hot water. The N Series gas fired water heaters can be powered by a blend of up to 30% hydrogen, and work on BioLPG as a drop-in solution for any off-grid site. The appliance is described as ‘out of the box’ design engineered and approved to be installed for use on blended gas.

All Rinnai N Series units are guaranteed to provide limitless volumes of temperature accurate hot water flows, provided fuel and water connections are constant. The Rinnai Sensei N Series is the first ever continuous flow hot water heating unit manufactured with stainless steel heat exchangers to be available in the UK – this gives a greatly extended working life at optimum performance to each of the four models in the range. Added to this are the market leading extended warranties, that accompany these hydrogen ready appliances.

The four models of the Rinnai N Series are: the N1600i giving 954 litres per hour; the N1600e (external) also giving 954 litres per hour (at 50 degrees); the N1300i giving 775 litres per hour and the N1300e also giving 775 litres per hours of temperature-controlled water at 50 degrees. The two 1600s have load profiles of XXL and are water efficiency class A rated, while the 1300s are load profile XL and are also water efficiency class A rated.

The range is also low-NOx less than 26ppm and the futureproofed continuous flow water heaters have several global patents on main components. The range utilises Rinnai’s patented advanced technology with a 13-1 turn down ratio – the largest on the market – with extremely quiet operation.

Integral controls on the units enable the water heater to achieve high efficiencies because of advanced burner control and high modulation ranges. This wide range of modulation means that energy usage is completely optimised as the water heater, through smart inbuilt controls, will only heat the water to the temperature required, thus preserving energy.

 

Other features include:

  • Flue up to 30+ metres for concentric
  • Turbo Fan
  • Built-in controller as standard on both internal and external models
  • Cascade Cable assembly allows up to 24 water heaters to be connected and function as one total and complete system. Any number of N-series Rinnai water heaters can be manifolded together enabling the largest capacities on the market.
  • Built in flue damper
  • Air inlet filter
  • Frost Protection – minus 15°C on the internal versions and minus 20 °C on the external versions
  • New PCB Design
  • Controller as standard – Lockable, set up of appliance, Temperature set up to 75°C
  • Maintenance Monitor for engineers

Chris Goggin details construction projects and financial funding directly related to future widespread UK hydrogen usage. Customers of energy and all related products will be provided with insight into projects that involve hydrogen use and production by big business inside the UK and EU.

 

 


Future UK energy options will be clean, domestically sustainable and free from market interference. Low carbon alternatives will be gradually introduced in replacement of environmentally harmful fossil fuels. A form of future energy that fulfils a low carbon criteria and can be domestically manufactured is hydrogen.

The UK government has recently released their latest report detailing a future approach to hydrogen dispersal. In brief, present calculations for the use of hydrogen as an upcoming UK energy option will be limited to decarbonising hard to reach sectors of industry and transport. If scientific data that proves hydrogen adoption yields beneficial results, hydrogen could be used to heat domestic and commercial properties.

Various hydrogen projects are being pursued, constructed and installed by leading international energy companies such as Shell and BP as well as several other large UK energy operators.

Spanish renewable energy company Iberdrola will invest €170 million in constructing and developing a green hydrogen facility at Felixstowe, England’s largest port. Manufacturing capacity will be around 14,000 tons a year with the ambition to double this figure in the near future. All green hydrogen that is produced will be used to power port vehicles and machinery.

Norwegian state-owned oil and gas company Equinor has submitted a bid for UK governmental funding of £16 million with the aim of constructing a second blue hydrogen facility in the Humber region of England. A final investment decision will be made in 2025.

The Hydrogen to Humber (H2H) Production 2 site will be located close to Equinor’s H2H Saltend project – another blue hydrogen facility. Operations will begin in 2028 if the construction and approving processes are not complicated by unforeseen events.

Both Saltend and Humber projects will use natural gas to produce blue hydrogen and utilise CCUS technology (Carbon Capture & Underground Storage) that will detain a vast majority of created emissions. Equinor also received £8.4 million in governmental funding, a figure matched by private investments to begin Saltend construction.

Another big company hoping to deliver a hydrogen production facility is UK oil and gas company BP. BP has submitted plans to the UK government detailing their vision in constructing and running a green hydrogen hub that will supply clean energy to local industry, businesses and homes.

BP’s HyGreen Teesside project will be located in the Northeast of England. Production and distribution of green hydrogen will be targeted for 2025. MOU’s (Memorandum of Understanding) have been agreed with potential local buyers of end-product green hydrogen, signalling large demand.

One such MOU has been signed with Northern Gas Networks (NGN). BP and NGN will see 2,000 local homes and businesses powered by hydrogen from 2025. It is hoped that the installation of a regional hydrogen hub can assist in enabling a functioning hydrogen economy across the region and nation.

HyNet North West is a £750 million joint venture project that includes several big names such as Cadent, Essar Oil UK and Eni UK. Two blue hydrogen production facilities and CCUS technology will be constructed and inserted into Essar Oil’s Stanlow Refinery and be transported through yet to be assembled infrastructure.

HyNet’s hydrogen hub will contribute 80% of the UK’s 5GW low-carbon hydrogen target that will be utilized in industry, transport and domestic heating. All produced hydrogen will be distributed across Northwest England and North Wales. Operations could begin in 2025.

Two major European economies in The Netherlands and Germany have embraced hydrogen as a potential contributor towards decarbonising national energy resources. The Netherlands is in the process of retrofitting 136,000 km of natural gas pipelines to transport hydrogen for industrial and domestic consumption. The Netherlands “National Hydrogen Network” will be ready for operations in 2031.

Germany is encouraging large domestic industrial hydrogen transitions and residential hydrogen dispersal. German steel producer Salzgitter will spend €723m to replace industrial procedure involving coal with green hydrogen. The German government is also experimenting with trials that use hydrogen to heat properties.

European economies are keen on a switch to hydrogen. At present UK plans are not definitive on the role of hydrogen in the national energy transition, while an influx of data demonstrates the positive benefits of hydrogen usage into policymakers expanding its role in the UK energy transition.

RINNAI HYDROGEN BLENDS READY 20% CONTINUOUS

FLOW WATER HEATERS BEATS STORED WATER

SYSTEMS AT PREMIER LEAGUE CLUBS 

Property experts and contractors have completed the installation of a complete new hot water delivery system at a top London Premiership football club, replacing an outdated stored cylinder configuration with a practical and economic hot water solution. The renowned club replaced their old traditional system with a specifically designed new energy efficient Rinnai continuous flow delivery on demand water heaters that offer and are certified for Hydrogen blends of up to 20%.

Rinnai water heating systems have been installed in almost all top UK Premiership clubs in the UK. The latest installation was completed at a stadium which is less than 20 years old and was considered ‘state-of-the-art’ once completed. The club had initially utilised a traditional stored system where hot water is kept heated until required. The new system is capable of delivering over 9000 litres of temperature controlled hot water each and every hour, non-stop.

A premiership football club will have huge peaks of demand and the site simply cannot afford to run out of hot water on match days. The demand is for the kitchens, the catering, the hospitality, the toilets and the extensive wash and showering facilities.

Continuous flow systems heat water upon demand meaning that fuel is only used when the system is operational.

The installation completed at this London premiership club included a manifolded bank of 10 Rinnai Sensei N series 1600i continuous flow water heaters together with the Nexus scale protection and a BMS Integration. All units featured Rinnai commissioning to secure long term warranty guarantees.

For Rinnai Ricky Lewis, Associate Director Corporate Sales, said, “We were able to demonstrate that the Rinnai system can yield financial reductions of nearly 20% of the running cost, over 30% of the upfront cost, over 15% in carbon footprint, over 75% in space, over 85% in weight compared to heated storage systems, creating a highly practical and economic solution for the client whilst lowering onsite carbon.”

Rinnai continuous flow water heaters are an integral part of the organisations H1 initiative which aims to utilise natural gas, Hydrogen blends, Hydrogen, LPG and Bio-LPG to lower onsite emissions. Rinnai continuous flow units are typically 30kg – a one-man lift, making the entire installation process far easier. Two sizes are available – 47kW and 58kW. Both produce 774 and 954 litres per hour at a 50-degree rise respectively.

Rinnai H1 continuous water heaters and boilers offer practical and economic decarbonization delivered through technological innovation in hydrogen and renewable liquid gas ready technology. Rinnai’s H1 option is centred on hydrogen, as it is anticipated that clean hydrogen fuels will become internationally energy market-relevant in the future; Rinnai water heaters are hydrogen 20% blends ready and include the world’s first 100% hydrogen-ready hot water heating technology.

UK customers of energy and energy related products are presently experiencing increased levels of financial turbulence. UK energy policy stipulates that fossil fuels will be gradually withdrawn from power options and renewable energy alternatives being used in replacement.

The UK government views renewable sources of energy as cost-effective and sustainable. When thinking of investing in a heating or hot water system for a domestic or commercial property it is worth pausing to consider current and future legislative direction.

As fossil fuels are targeted for actively being phased out of circulation, seeking a decarbonising heating and hot water system has become a prominent issue to UK customers. UK customers must now think logically when considering future energy and energy related products.

Current domestic UK policy is keen on expanding on and offshore wind farms for electrical generation. Construction of on and offshore wind farms are continuing with several beginning operations soon, or have already started production, such as Triton Knoll and Hornsea 2.

Only recently wind farms across the UK have set a record for secondary power generation. National Grid ESO said that during a 30-minute period on the 2nd of November, wind farms accounted for 53% of Britain’s electricity. The previous record was set last week when 19,936MW of electricity was provided towards national demand by on and offshore wind farms in a half hour period.

UK acceptance of renewable wind farms has been gradually growing since initial introduction in the 1980s. Communities strongly opposed plans to install wind farms as they were viewed as distorting natural scenery and therefore potentially affecting house prices.

Since the 1980s a climate emergency has been imposed and energy costs have reached exorbitant levels. A survey taken by RenewableUK demonstrates that the UK public now overwhelmingly supports the installation of new solar, wind (on and offshore) and wave power facilities to tackle on-going issues relating to the cost-of-living crises and energy costs.

RenewableUK gathered the following results when asking if the public was in favour of renewable energy installations that reduce electricity bills: 81% were in favour of solar energy, 76% of people backed offshore wind, 74% in favour of onshore wind and 72% support tidal and wave power.

To protect UK customers against market volatility and enhance domestic energy security, the UK government must seek alternative and sustainable methods of energy cultivation. As a result, renewable sources of energy will be steadily introduced into the UK domestic energy mix.

Public support and relaxed legislation will see renewable energy production and dispersal become widespread. Rinnai hold a selection of products capable of fulfilling any UK customer requirements regarding the purchase of a decarbonising heating and hot water system.

Rinnai’s H3 range includes all mainstream varieties of renewable energy alternative options including, solar thermal, heat pumps, Bio LPG water heaters and boilers and solar thermal tube collectors. All options focus on decarbonisation and reducing customer cost across all stages of product life cycle.

Rinnai can offer multiple avenues of cost reducing decarbonisation across various energy vectors. To create a healthier way of living, Rinnai is offering customer choices in hot water provision as well as heating domestic and commercial buildings through a wide range of renewable energy systems.

Rinnai’s solar thermal water heating systems are a decarbonising commercial option. Rinnai’s Solar thermal VirtuHOT units are designed and manufactured in conjunction with Naked Energy. Core design values of VirtuHOT has benefited from multiple workshops with experienced installers, whose valuable insights have been integrated into design and innovation. VirtuHOT saves up to 3.5x more carbon per m2 compared to conventional solar technology.

Rinnai’s H3 range of decarbonising products include commercial and domestic heat pumps that contain a variety of features: the HPIH range of commercial heat pumps is suited towards schools, restaurants and small retail outlets. Rinnai’s HPIH Monobloc Air Source Heat Pumps – 21, 26, 28 & 32kW range can allow for up to seven units to be cascaded together or operate alone as one unit. Once joined together – can serve increased demand for heating and hot water.

The HPIH series includes a range of controls and system peripherals which ensures that all technical machinations can be monitored. Rinnai’s HPIH commercial heat pumps also deploy the refrigerant – R32, which contains a low GWP. The HPIH use maintains an ERP rating of A++ making this range of heat pumps an ideal economic and environmental option for refurbishment projects.

Rinnai’s HPHP series of domestic heat pumps arrive with the ability to save up to 25% of power input, enhancing efficiency and operational performance. State-of-the-art technology added in the injection process outperforms gas compression technology and ensures that even with outside temperatures of –25 Celsius, heating and hot water of up to 60 + Celsius can still be delivered.

Rinnai’s HPI SL range models perform with ultra-low sound capability ensuring compatibility with areas that hold strict sound compliance standards. All units operate in three different modes: heating, cooling and DHW. All three models include specific system programmes that enhances product performance in all modes.

UK energy policy is aimed towards long term renewable energy production that is sustainable and free from outside malign market influences. Logical thinking infers that the UK customer must begin considering investing in decarbonising renewable heating and hot water provision. For more information and details contact

A GUIDE TOWARDS NET ZERO AND LOWER CARBON EMMISSIONS – UK ENERGY FOR THE FUTURE

 

 

 

Rinnai’s Chris Goggin lists a brief guide to national & local power variables that do, and might, in the future, supply the UK end-user and consumer. He looks at what is currently on offer and how that energy is manufactured and operates within the total UK mix of fuels.

 

As the UK is now firmly in an era of energy transition it is important that all interested parties – heating engineers, contractors, consultants and end-users – should be aware of what alternative energy is currently available and future options being actively considered.

Carbon heavy fuels are currently being phased out and replaced with a variety of low carbon alternatives. Instead of oil, natural gas and fossil fuel-generated electricity, renewable sources such as wind, wave and solar are being gradually introduced into the UK energy mix.

Biofuels such as BioLPG and RDME could also become UK market relevant along with green gasses such as hydrogen, which is supported by the UK hydrogen strategy and a myriad of pilot schemes across the UK. Energy policy in the UK is also planning to increase nuclear capacity with the construction of several new facilities, with the objective of providing low carbon electricity and potentially hydrogen. Following is a short exposition of each energy vector.

 

HEAT PUMPS

Heat pumps are an old but current technology – the first was invented by Peter von Rittinger in 1867. They can be considered zero carbon at the point of use. However, the carbon intensity of the system is dictated by the electrical grid generation method. A heat pump works by extracting heat from air outside and elevating its temperature using a compressor. Compressed heat Is then transferred into a body of water for heating and DHW.

Residual heat is stored in a hot water cylinder used for showers and baths. If installed correctly on to an appropriate property a heat pump will prove to be an energy efficient, effective tool of decarbonisation to the end-user.

Heat pumps are widely used in Scandinavian countries and other major European economies such as Germany. Mainstream UK media support heat pumps as do governmental grants that supply most initial purchase costs. Heat pumps are available with approved technology that encourages decarbonisation.

SOLAR ENERGY

 

Solar energy absorbs sunlight into photovoltaic panels which produces an electrical charge. This charge of electricity is then converted and transported into a domestic or commercial application. The UK government encourages domestic renewable energy installation. Homeowners can partly subsidise their solar panels through several governmental grants.
One example of UK homeowners incentivised towards solar thermal installation through a governmental scheme is the Smart Export Guarantee (SEG) which allows homeowners to receive payments for unused excess energy exported back to the national grid.

Solar power is viewed as holding the potential to contribute meaningfully towards the current and future domestic UK energy mix as well as multiple others across the globe. Only recently it was announced that Global renewable energy company – Low Carbon, has announced construction of 3 new large solar farms in Essex, Derbyshire and Buckinghamshire. Construction in Buckinghamshire will begin immediately. Once complete the facility will provide clean power to more than 7300 homes. Capacity of this site will be 23.4MW. Work on the 28.8MW Derbyshire and 23MW Essex locations will begin in the early new year – 2023. Similar installations are being constructed across every continent.

WIND ENERGY

Renewable wind energy is created when wind turbines are pushed by natural currents of air which is then converted into electricity via a generator. Current UK direction of onshore wind energy is convoluted. At present there is a ban on installing new onshore wind farms inside the UK. However, some media outlets report that the ban is lifted, others maintain the ban is still in effect. Offshore wind farm capacity is being expanded to meet future demand. There are several new installations being constructed inside UK and Irish waters.

Offshore wind facilities under construction and due to begin operations. Amongst the new sites to be introduced is the Dogger Bank Wind Farm off the coast of Yorkshire, Northeast England which will begin operations in 2025. £8.27 billion has been invested into this project and is a joint venture undertaken by SSE Renewables, Equinor and Eni Plenitude.

WAVE ENERGY

Wave energy is created once captured kinetic energy gathered by tidal movements pushes a turbine, which in turn produces electricity. Wave and wind energy rely on the same concept of utilising kinetic energy to generate power. Wave energy is considered 100% carbon neutral. Wave energy is expensive to produce and maintain but is also effective. UK policy adjustments in market and planning legislation could see wave power become expanded to meet future demand.

Further on-land construction work is continuing on the £35 million Holy Island Tidal Energy Scheme, in North Wales. 35 sq km of seabed will be used to generate as much as 240MW of clean tidal electricity, enough to power 180,000 domestic properties.

rDME

Renewable DiMethyl Ether – known as rDME – is a molecule-based fuel that can be produced through a wide range of renewable feedstocks which allows for quick and long-term sustainable production. rDME contains a similar chemical composition to Butane and propane and can be mixed with LPG in existing appliances to continue product operations.

rDME combusts cleanly and releases no “soot” emissions. It has many fuel properties that make it easily used in sites and appliances currently using diesel as a fuel. It has a very high cetane number, which is a measure of the fuel’s ignitibility in compression ignition engines.

Future capacity of rDME is set to rise sharply, further increasing the likelihood of rDME being introduced nationally at some stage soon. A demonstration plant is to be opened later this year, whist the first operational commercial site manufacturing rDME will be on-line in 2024 in Teesside.

LGP & BioLPG

LPG (Liquefied Petroleum Gas) is a low carbon fuel source that is supplied in two forms – propane and butane. BioLPG is 100% carbon neutral and produced through renewable feedstocks such as plant and vegetable waste. Both are considered future forms of carbon friendly energy.

LPG producers see a role for Bio-LPG in the future whether that be blended with LPG or BioLPG. The fuel can be theoretically drop in, meaning limited disruption and user familiarity. Companies have invested over £260 million to date in developing clean liquid gases, including bioLPG and rDME to market. During the transition to renewable liquid gases LPG will remain a valuable part of the low carbon energy mix.

As economies and industry attempt to decarbonise fuel supplies, demand for LPG and BioLPG will rise. Legislation amendments introduced by the US, EU and Japan could see both demand and produced volume of BioLPG increase.

NUCLEAR ENERGY

Nuclear energy occurs when a reaction from either uranium or plutonium is stimulated to generate electricity. The UK government is keen to expand nuclear capacity.

As of writing, it has been confirmed that the UK government will inject £700 million of taxpayer’s money in developing Sizewell C nuclear power plant. Doing so will provide 6 million homes with low carbon electricity for more than 50 years and strengthen national energy security.

HYDROGEN

Hydrogen is produced in various forms signalled by a spectrum of assorted colours: blue, green, pink, brown, grey, yellow and turquoise.

 

  • Blue hydrogen is formed once natural gas is heated with steam in a process called Steam Methene Reforming (SMR). Hydrogen and carbon dioxide are created as a result meaning that emissions must be captured and stored for blue hydrogen to become a low carbon fuel source.
  • Grey hydrogen uses Steam Methene Reforming without capturing any emissions.
  • Green hydrogen occurs once water molecules are split into oxygen and hydrogen using renewable energy to power an electrolyser which sits in a water basin. Green hydrogen is considered 100% carbon neutral and is regarded as a source of future clean energy.
  • Pink hydrogen is created through nuclear powered electrolysis whilst yellow hydrogen is produced through solar powered electrolysis.
  • Turquoise hydrogen is made using a process called methane pyrolysis which produces hydrogen and solid carbon.

 

An extensive list of major international energy companies, such as BP and Equinor has announced various projects costing billons that explore the introduction of hydrogen as a major contributor towards future global energy needs. Spanish renewable energy company Iberdrola are planning to develop a green hydrogen production facility at the UK’s largest port in Felixstowe. Iberdrola is prepared to invest £150 million in the project which is expected to be operational in 2026.

Closer to home the UK issued its Hydrogen strategy in 2021, with the objective of achieving 10GW of Low Carbon Hydrogen by 2030. The strategy is also seeing rapid developments in pilot schemes using 100% hydrogen across the UK.
