axi Heating and Worcester Bosch have taken a leading role in the drive to net zero

and low-carbon technology by showcasing hydrogen boilers in the UK’s first 100% Hydrogen Home public demonstration. The project will demonstrate the use

of hydrogen-fuelled appliances in a real- world setting, and signals a clear step in the progression of clean, sustainable hydrogen technology for heating, hot water and cooking in UK homes. The semi-detached properties,

built in partnership with Northern Gas Networks, the Government’s Department for Business, Energy and Industrial Strategy (BEIS) and gas distribution network company Cadent, will be located at Northern

Both companies have already been

Gas Network’s Low Thornley site, near Gateshead. Alongside the hydrogen boilers,

prototypes of hydrogen-fuelled fires, cookers and hobs will also be installed by partners working with BEIS on the Hy4Heat project. This real-world demonstration of the

technology marks a step change for the boiler manufacturers’ progression of hydrogen ‘from lab to field’, as more appliances are installed in trial projects across the UK and Europe.

involved in a number of trials including ‘HyStreet’ at Spadeadam in Cumbria, where hydrogen boilers were installed in specially built demonstration houses, to enable tests and research to prove the safety of converting homes and gas networks to hydrogen fuel. Karen Boswell, managing director at Baxi Heating UK and Ireland, said: “We are hugely proud to be a part of another ground-breaking hydrogen heating project and remain at the forefront of low carbon development.” Carl Arntzen, chief executive of

Worcester Bosch, added: “The trials underway are an important step towards a zero-carbon future and we’re proud that our hydrogen boiler prototype is playing a pivotal part.”


innai has completed a detailed report into the possible savings of 81% on carbon emissions if off-grid sites convert to using BioLPG as the main fuel source. BioLPG is conceptually renewable and sustainable, as it

is made from a blend of waste, residues and sustainably sourced materials. BioLPG, can be described as an eco- propane, the chemical makeup of this gas is identical to LPG and is therefore compatible with existing in situLPG products from a combustion perspective. BioLPG is a co-product of the biodiesel production

process. In the manufacturing process, feedstocks undergo a series of complex treatments. They are combined with hydrogen in a process called

hydrogenolysis, which separates and purifies their energy content. During the refining procedure, a variety of waste gases are produced that contain BioLPG. For every tonne of biodiesel, around 50kg of BioLPG is produced from this gas stream. This co-product is then purified to make it identical to conventional propane. The carbon factors associated with BioLPG used for this report are 0.0487kgCO2e/kWh. The Rinnai report highlights several off-grid building

envelopes that can benefit from high efficiency LPG fired water heaters and compares the carbon footprint from an energy transition perspective. The transition focuses on the carbon savings that can be achieved by shifting from widely used oil heating systems to LPG and then upgrading LPG to BioLPG. The applications are modelled for the report using hot water intensive buildings in the off-grid leisure & hospitality sector. Report author Chris Goggin said: ‘’This report sets out to

establish the environmental impact of a transition in energy types within typical off-grid high volume DHW applications.

The energy transition focussed on dominant off-grid energy sources namely oil, LPG and BioLPG. ‘’The report set out to establish the possible reductions

in carbon emissions if this energy transition was used to support widespread decarbonisation in an off-grid setting. The results demonstrate that there is potential for widespread decarbonisation whilst also providing an economical and technically feasible solution for consumers. ‘’As stated earlier in the report where LPG is already used

the incumbent water heating technology can still be used in the future when BioLPG switching is available. This would make use of the existing fuel infrastructure and heating technology which would lead to the potential for both capital and operational expenditure savings for end users. He concluded by saying: ‘’Further study should be

considered to establish the capital expenditure and operational expenditure impact when BioLPG fired appliances are compared to alternative energies and technology.’’
