UK energy regulator Ofgem announced that Scotland is about to launch the world's first test program where green hydrogen will replace natural gas used in cooking and heating. 300 homes in County Fife will be tested by Scottish gas company SGN with free hydrogen heating systems and cooking kitchens for 4 years. The aim is to test that carbon-free hydrogen, produced from water and electricity in an electrolysis process, can help achieve Britain's carbon targets.
To fuel the national innovation race to develop new green technologies and infrastructure, Ofgem has contributed $ 24 million to the project. What's more, it also allocated artswww 17 million to off-grid testing of using existing gas pipes to transport hydrogen over long distances - primarily to check the safety of such a solution. It cannot be denied that this is a good day for hydrogen at all, because it should be mentioned that Toyota has just presented the second generation of its hydrogen-powered Mirai and although these are distant topics at first glance, the truth is that in both cases we have to face with the same restrictions.
It's enough to mention hydrogen electrolysis, which can boast an efficiency of only 80%, which means that 20% of the electricity used in production is wasted. If this electricity was used for heating instead, it could in many cases prove to be a much more affordable way than hydrogen furnaces. However, the potential for green hydrogen in the UK is huge and taken seriously, largely because most homes there are heated with gas stoves, so if the infrastructure was available to handle the hydrogen, it could pay off in the end. Especially that Great Britain has set itself the goal of achieving neutrality in terms of greenhouse gas emissions in 2050.
“If we really want a carbon-free future, we need to replace methane with green alternatives like hydrogen. Sectors such as heating are difficult to decarbonise and the importance of gas networks to the current UK energy supply means that projects like this are key if we want to safely deliver low carbon energy to consumers, said Antony Green of the National Grid.
