Deep Sky

What it does

Deep Sky is a Montréal-based cleantech company that develops direct-air carbon capture (DAC) facilities. It builds, owns, and operates infrastructure to remove CO₂ from the atmosphere and permanently store it underground. The company uses a technology-agnostic approach, deploying multiple DAC technologies simultaneously at its facilities to minimize risk and accelerate industry growth. Its flagship facility, Deep Sky Alpha in Innisfail, Alberta, began operations in August 2025 and is the first facility to simultaneously deploy multiple DAC technologies. Deep Sky also has projects in development in Bécancour and Thetford Mines, Quebec, and in Manitoba.

Who it is for

Deep Sky serves organizations seeking high-quality carbon removal credits to meet sustainability targets. Its customers include Microsoft, the world's largest buyer of carbon dioxide removal (CDR), and RBC, Canada's largest bank. The company also partners with investors and stakeholders interested in funding scalable carbon removal projects. Its credits are designed for buyers who want verifiable, permanent geologic storage with full traceability of CO₂ molecules.

Why it matters

Carbon dioxide removal (CDR) is essential to reversing climate change, as reducing emissions alone is insufficient. Deep Sky addresses the supply gap in the CDR market by building infrastructure that can scale to gigaton levels. Its technology-agnostic model parallelizes cost reduction across multiple DAC technologies, aiming to engineer the lowest price. The company leverages Canada's advantages—abundant clean energy, massive geologic storage capacity (398 billion tons identified), and supportive government policies—to deliver high-quality, low-risk carbon credits. By securing land, power, government support, DAC technology, and geologic storage, Deep Sky provides certainty and scalability in a nascent industry.

Launch signal

Deep Sky Alpha, the world's first cross-technology carbon removal innovation hub, began operations in August 2025. The company secured a $40 million grant from Breakthrough Energy Catalyst, marking Catalyst's first support of a Canadian and a DAC project. Deep Sky has raised $130 million USD from investors including BDC Climate Fund and Breakthrough Energy Catalyst. The company has also secured offtake agreements with major buyers like Microsoft and RBC, signaling market confidence.

Brand and naming

The name "Deep Sky" evokes the vastness of the atmosphere and the ambition of removing carbon at scale. It suggests a focus on deep, permanent solutions (geologic storage) rather than superficial offsets. The brand positions itself as a project developer that owns and operates infrastructure, differentiating from technology vendors. The tagline "The World's First Technology Agnostic Carbon Removal Project Developer" emphasizes its unique approach of deploying multiple DAC technologies to reduce risk and accelerate cost reduction.
