Eden GeoPower tests electrical reservoir stimulation for underground hydrogen generation

Electrical Reservoir Stimulation Tested

Eden GeoPower is conducting field tests of its electrical reservoir stimulation technology. This process involves lowering large electrodes into boreholes deep underground and sending high-voltage electrical pulses between them. These pulses create miniature, subterranean lightning strikes that heat the rock, build pressure, and ultimately fracture it into a spiderweb of cracks.

Potential for Hydrogen Generation

One of the most significant potential applications for this rock-breaking technique is the underground generation of hydrogen. While hydrogen is considered a clean fuel, current production methods often require more energy than they yield and frequently involve methane, a potent greenhouse gas. Eden GeoPower's method could offer a new approach to hydrogen production.

Broader Applications

Beyond hydrogen generation, Eden GeoPower's technology has other potential uses. These include aiding mineral mining by making rock more permeable, tapping into geothermal heat sources, and creating geological storage areas for carbon. The company's tagline, "We break rocks with electricity," encapsulates its core innovation.

Field Test Location

The current field tests are taking place in a Boston suburb, on the edge of a horse farm. Electrodes are lowered hundreds of meters below ground into sandstone and ancient mountain rock formations. The discharges are faintly audible at the surface, indicating the process is actively fracturing the subterranean rock.
