Where to Find the Energy to Save the World

Simon Todd, a baby-faced, curly-haired Irishman and geologist who’d been at BP for 25 years, worked at a company called Causeway GT that was pursuing closed-loop systems for perhaps the most obvious idea: direct-use heating. His company aimed to tap right into the hot rock below large industrial buildings or regions—a big data center, a military base—to heat and cool those spaces. (Kind of like massive, available-anywhere versions of the geothermal heat pumps that some people use to heat their homes.)

Thanks to Maria Streshinsky for including our MD Simon Todd in the article together with a good summary of what we do.

We’d add that those “kind of like massive, available-anywhere geothermal heat pumps” will be able to 150 ºC (300 ºF) pretty soon.
