Deep Sky, a Montreal-based carbon-capture startup, has received a US$40 million grant from Breakthrough Energy Catalyst, a climate solutions venture firm founded by Bill Gates. The funding will support the construction of Deep Sky's first direct air capture (DAC) facility, named Deep Sky Alpha, located in Innisfail, Alberta. This facility is designed to test and validate up to eight different DAC technologies before scaling them to commercial levels. The project aims to capture carbon dioxide directly from the atmosphere, a process distinct from carbon capture and storage which targets industrial emissions. The grant marks Breakthrough Energy Catalyst's first investment in both a Canadian and a DAC project.
