Bush in 2003, latching on to a new enthusiasm for hydrogen vehicles during the first wave of real concern about climate change. “We can make a fundamental difference for the future of our children,” he said.

Now hydrogen is back – again. From the US to Australia, and the European Union to China, the past year has seen an almost daily torrent of multibillion-dollar government funding pledges, tests of new technologies from trains and planes to domestic boilers, industry statements and analyses, and championing by leaders such as UK prime minister Boris Johnson. “We’re finding it hard to keep up with,” says Simon Bennett at the International Energy Agency.

“The idea of a hydrogen economy is not new,” says Martin Tengler at analysts Bloomberg New Energy Finance. “Now we’re in another hype cycle. The question is: is it different, or not?”

Tengler is one of many who thinks it is. Meanwhile, another question hangs much heavier than hydrogen in the air: is it really a clean, green fuel to help combat climate change? Or does the significant lobbying of fossil-fuel interests for a hydrogen economy indicate other priorities?
