I think the real approach to geo should be more focused on decentralized use, instead of trying to do big arrays of holes, like solar, it's in the combination with localization of other technologies in array themselves that seem to offer the most opportunity.
Wind, solar, geo... they all work together better than as a single unit.
- chris_va 9y agoThat is sort of true from a grid perspective, but the math doesn't really work out well for geothermal. Geothermal has high capex, low opex, so you need it running 24/7 to amortize the high capital costs. If you combine it with renewables, you get high fluctuation of demand from the grid, which selects for the exact opposite technology (higher opex, lower capex). Natural gas fits the bill, so that is where the market is going.
