While many sectors can decarbonize through direct electrification, heavy industries like steel, heavy transport, and shipping require dense energy carriers that electricity alone cannot provide. Green hydrogen offers a viable path, but widespread adoption has been hindered by high costs and complex construction timelines. The global challenge is not just producing hydrogen, but making it affordable, scalable, and rapidly deployable for the industries that need it most.
In response, Stiesdal Hydrogen has deployed its 3.1 MW HydroGen Electrolyzer. This pressurized alkaline unit is industrialized for mass manufacturing and designed for dynamic operation, capable of ramping production up or down in minutes to match fluctuating electricity prices.
Unlike traditional custom-built plants, the Stiesdal system is a self-contained, outdoor-ready product. It requires no permanent buildings and allows for rapid “plug-and-play” installation (current site record: 16 days from delivery to First Hydrogen).
At the Glansager site, this technology powers a groundbreaking biological Power-to-X plant, a DKK 100 million partnership between energy group Andel and Nature Energy. Here, three Stiesdal electrolyzer units (totaling ~9 MW) produce green hydrogen which is injected directly into a biological methanation system. This hydrogen combines with captured CO₂ to produce e-methane, significantly boosting the output of green gas.
The Glansager plant is a real-world demonstration that green hydrogen is a scalable climate solution today. By coupling Stiesdal’s fast-ramping electrolyzers with biogas production, the facility proves how hydrogen production can be economically optimized by capitalizing on low spot-market electricity prices.
Key impacts:
Efficiency boost: The integration of hydrogen is projected to increase the methane content of the biogas by up to 78%, adding approximately 12,000 cubic meters of green gas to the daily production.
Grid balancing: The system demonstrates how electrolysis can stabilize power grids by acting as a flexible load, turning excess renewable energy into storable fuel.
Sector coupling: The project serves as a blueprint for decarbonizing hard-to-abate sectors, proving that with industrialized technology, Power-to-X is practical, affordable, and ready for global export.
