Lemissoler Navigation’s four dual-fuel methanol bulkers illustrate exactly why geological hydrogen matters: it could slash the carbon cost of producing the methanol those ships will burn.
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.
A validated hybrid AEM electrolyser from P2H2 and Repsol hits efficiency, flexibility and durability targets simultaneously — raising fresh questions about when geological hydrogen will make electrolysis itself redundant.
