Developers eye potential of stimulated hydrogen

Laboratory and pilot-scale results suggest production route could achieve both low carbon intensity and competitive costs, according to paper published by Oxford Institute for Energy Studies

Interest is growing in stimulated geological hydrogen as its long-term potential to compete with natural, green and blue production routes captures the attention of developers and policymakers. The process aims to engineer favourable subsurface environments to actively generate hydrogen from reactive rock formations, using stimulation techniques such as thermal, electrical, chemical or mechanical methods. The US Department of Energy has identified the development of subsurface stimulation technologies as a critical pathway for unlocking geological hydrogen as a scalable, low-emission energy resource. Initiatives are also underway in Europe and Canada, where both public agencies and private f
