The idea works a lot like a giant radiator, connecting 50-60 kilometres of wellbores into a closed loop of water, circulated using sub-surface heat.According to Redfern, the resulting “Eavorloop” can generate enough electricity to power up 20,000 homes, in addition to offering options for direct heating.
And while the idea started in orphaned wells, the company says the technology can be used anywhere, ideally optimizing proximity to towns, cities and industries using the energy., and in traditional geothermal volcanic settings, like New Mexico.It’s a prospect now also now appealing to energy-starved countries overseas. Construction of the company’s first commercial project is currently underway in Germany.
