Hydrogen boiler unveiled

Worcester Bosch has officially revealed its new boiler prototype, which can run on 100% hydrogen gas.

 

Worcester Bosch believes hydrogen gas is solution for reducing carbon emissions in heating. Last year, the UK committed to a target of net zero carbon emissions by 2050. A bold target that requires new technology and industry changes across a number of sectors in order to become a reality.

Steps are already being taken, for example in transport, where electric and hybrid cars have become more common and accessible. But for the heating and hot water industry, removing carbon is much more difficult, largely because of the existing infrastructure, where the majority of UK homes use natural gas for heating.

Yet, with 15 per cent of UK greenhouse gases coming from heat in our homes, it is quite clear that the UK will not meet its climate change targets without a change in home heating technology and fuel.

Replacing natural gas boilers with hydrogen gas may be the simplest solution to the nation’s heating problems. The main by-product of burning hydrogen gas is water, meaning that it is a carbon-free fuel source and could be a key method to help decarbonise heating and hot water in UK homes.

The Worcester prototype hydrogen boiler fits into the same footprint as a current natural gas boiler. Hydrogen-ready boilers will be a direct replacement to natural gas, burning natural gas on its first day up until the switch to hydrogen takes place. Also, with a similar build to existing boilers, installers will already have most skills necessary to fit these products too.

Over the last few years, leading boiler manufacturer Worcester Bosch have not only been advocating for hydrogen, but they have also developed a prototype boiler that can run on 100 per cent hydrogen gas.

The prototype has been designed to also run effectively on natural gas. This means that in the future if hydrogen gas becomes reality, those who have a ‘hydrogen-ready’ boiler can simply convert to hydrogen without the need for an entirely new heating system.

Martyn Bridges, director of technical communication and product management at Worcester Bosch, said: “The development of hydrogen-fired boilers will mean millions of existing heating systems in our homes can be saved, rather than the entire system needing to be replaced.

“The beauty of hydrogen as an alternative to natural gas is that as well as water as a by-product, Worcester Bosch has developed a technical solution that will feel familiar to both homeowners and installers. The gas network is also in place, so homeowners won’t experience any major infrastructure disruption.

“With fully developed prototypes, various trials planned and many heating engineers and manufacturers in agreement that this could be a viable solution to decarbonise heating and hot water, we are hopeful that the future will be hydrogen.”

Whitepaper tackles legionella risk

Low occupancy rates in commercial buildings could be leading to a ticking time bomb of water quality issues according to Guardian Water Treatment.

To help building owners take the right steps to prevent these issues, in particular legionella, the company has launched a new whitepaper – Locked down but not forgotten.

In the whitepaper, Guardian draws on its own data from over 30,000 samples taken from commercial buildings, predominantly in London, over a six-month period starting from April 2020 (when the first lockdown began).
