en.Wedoany.com Reported - Denmark-based Stiesdal Hydrogen has launched a 6.5MW pressurized alkaline electrolyzer system with a capital expenditure (CAPEX) below €500/kW, significantly undercutting its European competitors.

A subsidiary of renewable energy technology company Stiesdal, Stiesdal Hydrogen stated that this modular system, suitable for outdoor deployment, was developed based on its existing 3.1MW platform. That 3.1MW platform was previously used in a small-scale project by European Energy in Denmark.

The company says the new system has more than double the capacity of the original platform but occupies essentially the same footprint, enabling a system CAPEX below €500/kW. It is currently unclear whether this system includes water treatment and other Balance of Plant equipment.

"With this upgrade, we have halved the cost per megawatt compared to the current European market average," said Esben Baltzar Nielsen, Head of Sales at Stiesdal Hydrogen. "Calculated per megawatt, operational and maintenance costs are also reduced by approximately 50% compared to the 3.1MW platform."

This price point is notably lower than other publicly disclosed electrolyzer prices currently available in Europe.

Earlier this month, Nel launched its new 25MW pressurized alkaline electrolysis system with a CAPEX of approximately $1,450/kW; UK-based PEM electrolyzer company ITM Power indicated its system cost is around $1,166/kW. However, both include auxiliary system equipment.

This price level puts Stiesdal Hydrogen in the same range as Chinese manufacturers, whose technology costs are generally considered to be around $500/kW.

In addition to low cost, Stiesdal also stated that the system can operate between 15% and 100% of rated power, with a load ramp rate of 2% per second, and the electrolyzer stack lifetime can reach 60,000 hours, approximately 7 years, of operation at 100% load.

Currently, electrolyzer manufacturers are intensifying efforts to consolidate their market foundation. As projects progress slowly and competition from Chinese companies intensifies, more and more Western original equipment manufacturers (OEMs) are seeking to reduce cash burn and align production capacity with market demand.
