Yara’s 800,000 t/yr CCS project at Sluiskil sets a commercial benchmark for industrial CO₂ capture — and frames a strategic question for natural geological hydrogen: when subsurface CO₂ storage scales up, does it crowd out or complement the geological hydrogen value chain?
A University of Oregon study pinpoints iron-ion contamination as a primary degradation driver in alkaline electrolysers operating under intermittent solar and wind power — a finding that sharpens the cost case for geological hydrogen, which requires no electrolysis at all.
As green hydrogen via electrolysis remains constrained by well-to-wheel efficiency losses of roughly five times that of battery-electric drivetrains, natural geological hydrogen is gaining attention as a pathway that bypasses the electrolysis bottleneck entirely.
The Belgian Council of Ministers has approved a €3.5 million national scientific exploration programme to determine whether natural hydrogen exists in Belgian subsoil — a survey, not a discovery.
As carbon capture and utilisation infrastructure expands, geological hydrogen projects in Europe explore potential CO₂ storage and transport co-location opportunities.
Major carriers and port operators are backing maritime decarbonization efforts as both electrolytic green hydrogen and geological hydrogen exploration accelerate in parallel.
The HY4Link project will connect Belgium’s seaport hydrogen import infrastructure through Luxembourg to industrial demand centres in France’s Grand Est region by 2031.
