Giga-scale green hydrogen: ‘Developers are being unrealistic about levelized costs’

Recent announcements such as the $70bn, 28GW Western Green Energy Hub in Australia, the 15GW Oman project or the relatively meagre 4GW Helios project in Saudi Arabia and HNH in Chile have captured the headlines but there is one interesting point they all have in common. Each project’s estimated levelised cost of hydrogen works out to be about $2.50/kg. Keynumbers founder John Poljak writes that the cost of producing H2 at gigawatt-plus projects will be much higher than companies are projecting, and differ by country.
