How AI Is Powering Europe’s Hydrogen Leap

Enapter's smart electrolyzers cut costs and downtime as Al enters clean energy production

23 May 2025

Europe’s hydrogen sector is turning to artificial intelligence to improve efficiency and reduce costs, as developers seek to scale up clean energy production.

German electrolyzer maker Enapter has introduced an AI-driven control system that adjusts hydrogen output in real time. By processing data from operating machines, the software cuts electricity use and anticipates maintenance needs. The company said this delivers efficiency gains of up to 4 per cent — a small figure that could have a significant impact when applied across the continent’s growing base of hydrogen projects.

Electrolyzers, which split water into hydrogen and oxygen, are increasingly powered by renewable electricity. Because output from wind and solar is intermittent, traditional systems face difficulties adjusting. Enapter’s software allows plants to respond instantly to fluctuations, generating more hydrogen from the same renewable input while reducing downtime.

Electricity accounts for the largest share of hydrogen production costs. Even marginal savings therefore matter for projects in steelmaking, chemicals and heavy transport, sectors targeted for decarbonisation under EU plans. “It is a digital leap that could redefine costs and reliability in tandem,” said one analyst.

The shift also raises questions for regulators. As remote updates and predictive systems become widespread, cybersecurity and safety will draw greater scrutiny. Facilities handling explosive gases may require additional oversight to ensure AI-driven controls interact safely with hardware.

For now, industry momentum is leaning towards rapid adoption. Supporters argue that digital tools accelerate learning curves, lower operating expenses and help hydrogen compete with fossil fuels.

Analysts expect AI features to become standard in the next wave of electrolyzer plants, rather than optional add-ons. Europe’s strategy to expand hydrogen supply is increasingly tied not only to advances in engineering but also to software capable of extracting more value from renewable power.

If such gains continue, AI could help shift hydrogen from a promising technology to a mainstream part of Europe’s clean energy system.
