Hydrogen boilers – the key to green heating

Posted by: Carly Temple on 25th March 2021

With the only by-products of green hydrogen being oxygen and water, there is no doubt that heating with this gas is entirely climate-friendly. Although most boilers use natural gas (methane) to heat our homes, industry leaders such as Valliant and Worcester Bosch are paving the way for carbon-free energy by extensively researching and trialling hydrogen-ready boilers so they can be rolled out when the government give the go ahead.

Why use hydrogen?

Hydrogen is a colourless, odourless gas which can be obtained from different substances on earth such as water; meaning that there is an infinite supply. Power is not compromised with the use of hydrogen either – the gas has previously been used to lift the space shuttle and power planes. Interestingly, as well as a fuel, the gas can act as a coolant too. With the process of producing hydrogen giving off zero carbon emissions, it is fully sustainable.

Heating with hydrogen – what’s different?

With its natural gravitation towards oxygen, hydrogen generates heat and water as a by-product when the two gasses meet. As hydrogen is a carbon-free energy carrier, the combustion produces no carbon dioxide or carbon monoxide.

The key to green heating?

A hydrogen-ready boiler is able to burn either natural gas or 100% hydrogen. This change in functionality can pave the way for gas distribution networks to carry hydrogen. In-depth studies have determined that making this change to the gas distribution networks is feasible and could assist with ensuring that the heating of properties is decarbonised. This climate-friendly push is an important part of helping to meet the UK’s 2050 ‘Net Zero’ carbon target.
