Of all the technological progress of the past few decades, there is a good argument to be made that a series of fossil fuel industry innovations that helped spark the U.S. shale oil boom have had the single largest effect on the course of global geopolitics, and the world’s biosphere. Horizontal drilling and hydraulic fracking shifted the U.S. from being a net fuel importer to exporter—a realignment of the world’s strategic chessboard currently being demonstrated in the fleets of American oil and natural gas tankers helping circumvent Russia’s energy blockade of Europe. At the same time, all that new, cheap fuel helped prolong the U.S.’s carbon addiction for years, with incipient renewables unable to compete against natural gas.But that drilling technology may yet have a climate upside. Last month, Houston-based startup Fervo announced the successful test of a first-of-its kind commercial-scale power plant, which uses the shale oil drilling innovations to produce zero-emission geothermal energy. While horizontal drilling allows oil producers to access new seams of fossil fuels, in Fervo’s case, the company is drilling sideways into hot, porous rocks heated by tectonic activity. The company then pumps water through those rocks in order to generate steam and produce electricity. Right now, its project in northern Nevada is capable of producing about 3.5 megawatts of energy, or enough electricity to power about 2,600 homes. Once the plant gets hooked up to the grid later this year, that electricity will be used to power Google data centers and other Alphabet operations.Unlike solar and wind energy, which only generate energy when the sun is shining or the wind is blowing, geothermal plants can provide a constant stream of power, which is crucial to balancing the grid. Currently, geothermal energy accounts for about 0.4% of U.S. electricity. But, like in the U.S. fracking boom, Fervo’s technology could make it feasible to develop geothermal power plants in many more areas where it wouldn’t have made financial sense before, a change that could help raise geothermal energy as a serious player in decarbonizing the U.S. grid.(Adapted from https://shorturl.at/laUsF)What would most likely happen if Fervo’s drilling technology becomes widely adopted across the U.S. …
