The evidence is clearcut: no further public funds should be directed towards hydrogen vehicles. Any hydrogen support should focus on decarbonising existing use by industry of polluting hydrogen made from fossil fuels. (6/6)

The UK’s influential Climate Change Committee said this year it sees “no role” for hydrogen in powering road transport. By 2050, all road transport will convert to electric vehicles - including heavy goods vehicles. (5/6)

The problem? A lack of reliable hydrogen supply, technical issues and high maintenance costs.

Clean, green hydrogen made from renewable electricity is in scarce supply globally. Using it to fuel vehicles that can instead be directly electrified is a low priority. (4/6)

“There’s been a lot of hydrogen bus trials that have failed. I don’t know of any electric bus trials that have failed.” - Tom Baxter, visiting Professor of Chemical Engineering at Strathclyde University. (3/6)

“I’ve got a list of 27 failed hydrogen bus projects around the world and it’s just the same story again and again.” - @davidcebon.bsky.social, Professor of Mechanical Engineering at Cambridge University and Director of the Centre for Sustainable Road Freight. (2/6)

Instead, the focus should shift toward green hydrogen produced from renewable energy — supporting local industries, like fertiliser and steel production, that lack other viable decarbonisation options. (4/4)

Turning away from unrealistic export projects like this presents a real opportunity for Australia to rethink its hydrogen strategy. (3/4)

Decision makers in Australia look to be digesting the reality that using fossil fuels to make hydrogen, shipping it halfway across the world and deploying it in sectors that can otherwise be directly electrified is about as emissions-intensive, energy inefficient and uneconomic as you can get. (2/4)

⬜ What about geologic hydrogen, found occurring naturally? Current global geologic hydrogen extraction is roughly equal to the power in a single wind turbine. None detected to date is commercially exploitable. (4/4)

🟦 What about blue hydrogen, made from natural gas with carbon capture and storage? Blue hydrogen plants generally remove only 50%–60% of the overall plant-wide CO2 emissions produced. (3/4)

🟩 Green direct electrification is usually much cheaper than green hydrogen. As a result, green hydrogen may only be a useful decarbonization strategy if it's made where electricity is 100% green and inexpensive, and green hydrogen replaces fossil fuel hydrogen. (2/4)

With a UK government decision pending on hydrogen heating, and a trial still scheduled in the Scottish town of Fife, it is now more critical than ever to base policy on sound scientific evidence, which has never been more clear-cut. (6/6)
