Keith Baker: THERE are many good reasons to support using hydrogen to decarbonise our energy supplies, but when you look beyond the hype it’s easy to see why some are much more promising than others, and so we need to separate the hydrogen wheat from the chaff. The Scottish Government’s consultation on the Draft Heat in Buildings Strategy includes many mentions of hydrogen and notes that the government is seeking to “understand the potential for hydrogen for heat, including identifying those buildings and areas where hydrogen is most likely to be the best option for delivering our targets”. However, as regards heating homes, the simple answer is that the potential is very limited, and the number of cases where it would be the best option falls in the range of very small to zero. But I’ll get to the reasons for that later. If we are to have any chance of averting catastrophic climate change, we can forget everything but green hydrogen (advocates of CCS can get back to me when its working at scale and economically competitive, but I won’t be holding my breath).
