Exposing the Learning-Curve Myth: Why Enhanced Geothermal Cannot Follow Solar’s Cost Trajectory

12 min read

Enhanced geothermal systems have been positioned by advocates as a scalable source of firm, low carbon electricity that can complement wind and solar. The idea has appeal. The deep heat of the crust is available everywhere and geothermal energy is not intermittent. Policy agencies have published scenarios showing EGS costs … [continued]

Fracking Hydrogen From Rocks: Clever Tech, Tough Economics

11 min read

Engineered mineral hydrogen is an elegant idea. Water reacts with iron rich magnesium and iron rich, silica poor igneous rock — ultramafic — from Earth’s mantle rocks to release hydrogen, and with the right chemistry and temperature you can raise reaction rates and collect a clean product. In the lab … [continued]

Shale’s Self-Inflicted Crisis: Wastewater Injection Is Sinking Profits

8 min read

The shale industry is facing an entirely predictable consequence of its own making. Across major shale-producing basins, particularly East Texas and the Permian, excessive wastewater injection practices have created areas with extreme overpressure, driving up the cost of new drilling operations and threatening the economic viability of shale production in … [continued]
