What Deep Sky does
Deep Sky Corporation is a Montreal-based, privately held carbon removal project developer founded in 2022 that operates a technology-agnostic platform for permanent carbon dioxide removal. Its flagship facility, Deep Sky Alpha in Innisfail, Alberta — operational since August 2025 — is described as the world's first cross-technology direct air capture centre, hosting up to 10 DAC systems simultaneously with 3,000 tonnes-per-year nameplate capacity and proprietary benchmarking software that compares competing DAC technologies under real-world Canadian climate conditions. The platform is being expanded with Deep Sky Manitoba (planned 500,000-tonne/year commercial facility, construction starting 2026), Deep Sky Thetford Mines (Quebec's first geological CO2 injection from ambient air; $2B+ planned investment), and Deep Sky Bécancour (largest geological storage study in Eastern Canada), with an aggregated technology portfolio spanning roughly 18 DAC vendors including Airbus, GE Vernova, DACMA, Climeworks, Skyrenu, Carbon Atlantis, Greenlyte, ReCarbn, Avnos, Mission Zero, Phlair, NEG8 Carbon, Skytree, Carbyon, and Sustaera, plus ocean capture (Equatic) and mineralization storage (Carbfix).
Deep Sky monetizes its infrastructure through "Deep Sky Tonnes" — verified, permanent carbon removal credits sold to enterprise and institutional buyers via multi-year (typically 10-year) offtake agreements; contracts to date include RBC and Microsoft (founding buyers, 10,000 tonnes plus options on up to 1 million tonnes), TD Bank Group (18,000+ credits over 10 years), ENGIE (up to 15,000 credits), Lufthansa Group (multi-year), and Rubicon Carbon (first DAC provider in its portfolio). Pricing is undisclosed and negotiated per contract; industry reference pricing for DAC sits at $400–$1,000 per tonne, with a stated 2030 target of $250–$350. The go-to-market combines direct enterprise sales with channel partnerships (SMBC for Japan, ENGIE for Europe, Rubicon Carbon for aggregated demand, Senken for aviation vetting), and is supported by a content- and PR-led marketing program and grant/non-dilutive financing including a USD $40M Breakthrough Energy Catalyst grant, nearly $6M from Natural Resources Canada, and a bespoke credit facility with Finalta Capital.
Capital structure is highly fragmented across institutional and strategic investors — Investissement Québec, Brightspark Ventures, Whitecap Venture Partners, OMERS Ventures, BDC Climate Fund, BMO, National Bank of Canada, and Breakthrough Energy Catalyst — with cumulative funding of $130M+ reported as of mid-2026. Customer verification is anchored by Isometric as the official carbon removal registry for Deep Sky Alpha, providing third-party MRV with 100% CO2 molecule traceability from capture through permanent geological storage.
