Less than 1 percent of all hydrogen produced today comes from renewables. Is that about to change? The vice president of Siemens Middle East just predicted that green hydrogen will assume the mantle of the “new oil” in the coming decades. A lot of big industrial companies and oil majors are taking another serious look at hydrogen. Why? In an era of extremely cheap renewables that are increasingly being curtailed, hydrogen production could finally become an attractive use case, due in part to the emerging regulatory pressures on existing hydrogen production. This week, we talk with Ben Gallagher, an expert on emerging tech at Wood Mackenzie. He’s the author of a new piece of research on the green hydrogen market. Ben will help us understand what’s different about today’s hydrogen hype.

Zero-carbon hydrogen has been injected into a UK gas network for the first time in a groundbreaking trial that could help to reduce carbon dioxide emissions. The 20% hydrogen and natural gas blend is being used to heat 100 homes and 30 faculty buildings at Keele University in Staffordshire. Unlike natural gas, when hydrogen is burned it produces heat and water as opposed to carbon dioxide. The hydrogen is captured using an electrolyser, which runs electricity through water to split it back into hydrogen and oxygen. This can then be injected into existing modern gas networks, with no need for customers to change appliances or pipework. The Health and Safety Executive granted the project exemption in 2018 from the current 0.1% limit on hydrogen in the UK gas network after an extensive examination of evidence to ensure it would be safe. Keele University was identified as an ideal location, because it owns and operates a private gas network that can be isolated from the main network.
