Bill Gates-Backed Fund Bets $40 Million on Carbon Removal Firm Deep Sky

The clean-tech venture firm founded by Bill Gates is providing a $40 million grant to carbon-capture startup Deep Sky Corp., which seeks to build large-scale facilities to clean carbon from the air.

The world will need to remove billions of tons of carbon dioxide from the atmosphere by mid-century to reduce the risk of extreme climate change. Montreal-based Deep Sky aims to provide millions of tons of CO2 removal that will be stored underground. The startup was founded by Frederic Lalonde, chief executive officer of Hopper Inc., a Montreal-based air-travel application company that’s one of Canada’s most valuable technology firms.

The committed funds come from Breakthrough Energy’s Catalyst program, a platform investing in emerging climate technologies. They will be allocated to the construction of Deep Sky’s first plant in Innisfail, Alberta. The facility, requiring an investment of more than C$100 million ($70 million), will test and identify the most promising technologies, and start scaling from there. Other potential storage projects are in the works in Quebec.

Deep Sky expects to start operations and delivering carbon removal credits in 2025. The firm announced in November that it sold credits to Microsoft Corp. and Royal Bank of Canada, but did not provide any financial details.
