By contrast, Latimer says, Fervo Energy will be able to experiment with how to build geothermal energy in a way tailor-made for capturing CO2. “It’s a totally unexplored place,” he said. “What would you do differently in the design of a geothermal power plant if youThe company plans to design and engineer the plant at one of its demonstration
sites — possibly in northwestern Nevada, central Utah, or another spot yet to be announced. It will likely be in the Western United States, where geothermal heat is more easily accessible. There are still many details to work out. It’s not enough to simply take carbon dioxide out of the air — ideally, it also needs to be stored deep underground, often in porous stones filled with salty water. Pilorgé says that one of the challenges will be placing geothermal plants in areas where such aquifers are readily available.
One potential criticism of the project is that it focuses on drawing carbon out of the air instead of preventing it from getting there in the first place. After all, geothermal energy could play a key role in shifting the electricity grid over to renewables. Unlike wind and solar, a geothermal plant can be on all of the time, producing electricity even when the wind isn’t blowing or the sun isn’t shining.
We've already started, here in Cornwall
So cool!
