US firm explores electrical pulses to unlock hydrogen from deep rock

A US-based startup is investigating a novel approach to hydrogen generation that harnesses electrical pulses to crack rock formations deep underground, potentially opening a new pathway for clean energy production. Eden GeoPower's method relies on what researchers describe as 'underground lightning'—targeted electrical discharges designed to fracture mineral-rich rocks at depth. Once fractured, the exposed rock surface can interact with water, a process that laboratory experiments suggest produces enhanced quantities of hydrogen.

The company has progressed from controlled laboratory settings to field trials aimed at validating the commercial viability of the technique. Current testing phases focus on understanding how the electrical pulse method performs under real-world geological conditions and whether the hydrogen yields achieved in labs can be replicated at scale.

If successful, the technology could represent a significant development in hydrogen production alternatives. Traditional hydrogen generation methods rely heavily on fossil fuels or electrolysis powered by electricity. An approach leveraging deep geological reactions could potentially tap into abundant natural resources while reducing dependence on conventional energy sources.

The trials remain ongoing, with researchers working to establish whether the method can achieve the efficiency and cost-effectiveness required for commercial deployment. The outcome could influence hydrogen production strategies globally and potentially contribute to broader decarbonization efforts in regions seeking low-carbon energy alternatives.
