He cited the cost of renewable power, at least in Europe, as a key reason why the economics of green hydrogen simply do not stack up. Liebreich even took issue with the developer of a major green hydrogen and ammonia project in South Africa, who said he could achieve a cost of $2/kg for green hydrogen on the back of cheap and highly efficient solar power. “Count me out. You are not going to do hydrogen for $2/kg, Liebreich said. “I was in the [Mideast] Gulf earlier this year, and they are struggling, in much of the Gulf, to get to $5/kg,” he told the conference.
Liebreich found an ally in the room in the form of Octopus Energy, one of the UK’s fastest-growing green power suppliers and, until recently, a hydrogen enthusiast. William Rowe, who launched the Octopus hydrogen business in 2021, said the firm’s original idea had been to produce green hydrogen from cheap curtailed renewable power, allowing it to produce at around £5/kg ($6.8/kg) delivered to the end-user. Having got a project up and running, Octopus realised the economics did not work as they had expected. “The reality was, it is just not true,” said Rowe. Flexibility and storage now look to be a better way to manage curtailed power, while price signals in the market will decrease the overall amount of curtailing on the system, he said.
The killer blow for Octopus’ foray into hydrogen was cost inflation in the supply chain, Rowe said. “What we found was that we were actually getting inflation on the supply chain for hydrogen rather than deflation. There was no real opportunity to bring the cost down in many of the elements of what we were trying to buy.”
