GeoPura vs. AFC Energy28 Apr 2026 21:56
Anyone who has read the article about GeoPura and Sunbelt Rentals might, at first glance, think: "Damn, the competition is pulling away." But if you take a look "under the hood," you’ll see that AFC Energy has some damn strong aces up its sleeve when it comes to costs.
The crucial point is fuel flexibility. GeoPura relies on PEM cells. The problem? These things are real divas. They require 5.0-grade hydrogen (99.999% purity). Transporting that stuff is a logistical nightmare and astronomically expensive.
This is where the AFC advantage comes in:
AFC’s alkaline systems are significantly less "demanding." Key phrase: ammonia cracking. AFC can generate hydrogen on-site from ammonia. As an energy carrier, ammonia is much easier to handle, cheaper to store, and offers a higher energy density during transport than compressed hydrogen. This massively drives down operating costs (OPEX)!
Then there is the issue of CAPEX:
While GeoPura relies on expensive precious metals like platinum for its PEM cells, AFC gets by with significantly cheaper materials. Less platinum means lower manufacturing costs for the units. This is a lever for scaling that should not be underestimated.
My conclusion: GeoPura may currently be dominating the headlines with large rental fleets, but AFC is playing the long game based on the cost per kWh. If the S-Series delivers on its promised efficiency and the cracker technology rolls out on a broad scale, it will be difficult for PEM-based systems to compete on price.
The market for temporary power in the UK is huge—there is room for both players—but technologically, AFC definitely has the potential to become the cost leader. What do you think? Will we soon see that "aha moment" reflected in the margins?
