Expect a lot more announcements about shutting down hydrogen for energy projects like the recent one from Equinor, Aire Liquide, and Eviny.
Every week there are breathless announcements about some new hydrogen for energy play. It might be about a 121 km hydrogen passenger train route. It might be about a memorandum of understanding to maybe, at some point in the future, build a lot of renewables to make hydrogen in Namibia. It might be about a plane flying for ten minutes with one propeller turned by hydrogen.
The one that brought this to mind this morning was the announcement that Equinor, Air Liquide, and Eviny were completely. They had a site picked out next to an Equinor refinery where they were going to build an electrolysis plant and manufacture six tons of liquified hydrogen a day. That’s just operational costs, by the way. Assuming an 80% utilization factor, the electrolyzer would be in the 16 MW range. As the, “CAPEX requirements are currently in the range of USD 500-1 400/kWe for alkaline electrolysers and USD 1 100-1 800/kWe for PEM electrolysers, while estimates for solid oxide electrolyser cell electrolysers range across USD 2 800-5 600/kWe.” Assuming the lower end of this range, let’s take $1,200 per kWe, suggesting an electrolyzer only CAPEX of about $19 million.
This is all simple math that was available in 2021 when the project was announced with much fanfare. Not that anyone whipped out a napkin and a Bic pen to do this. Where’s the fun in that?
