What They Do
Planetary Technologies specializes in ocean-based carbon removal through coastal ocean alkalinity enhancement (OAE), focusing on restoring seawater chemistry to capture atmospheric CO2 effectively (source: planetarytech.com). The company’s patented process recovers natural alkaline minerals from industrial byproducts and introduces purified alkaline minerals such as magnesium hydroxide or calcium hydroxide into coastal outfalls at existing infrastructure sites like power plants and wastewater treatment facilities (source: xprize.org). Their Ocean Carbon Platform automates alkalinity addition, monitors ocean safety, and measures and monetizes carbon removals, targeting carbon removal buyers, climate-tech customers, and industrial partners rather than traditional utility clients (source: xprize.org). Planetary emphasizes scientific validation, third-party verification, and transparency in its operations, leveraging existing coastal infrastructure to scale its impact efficiently (source: lobbycanada.gc.ca). Their approach results in durable carbon removal, seawater restoration, and reduced ocean acidity, positioning them as a leader in climate technology innovation (source: cbinsights.com).
Projects & Track Record
Planetary Technologies has demonstrated its ocean alkalinity enhancement technology through a multi-year project in Halifax, Nova Scotia, which has been operational for over two years and is scaling from 25,000 tonnes to 100,000 tonnes of CO2 removal annually (source: unreasonablegroup.com). This demonstration project has achieved the issuance of the first seawater restoration credits on an accredited registry, marking a significant milestone in verified ocean carbon removal (source: unreasonablegroup.com). The company is actively developing additional ocean carbon removal projects worldwide, leveraging its modular deployment model that integrates with existing coastal infrastructure such as power plants and wastewater treatment facilities (source: xprize.org). Partnerships with major carbon removal buyers including Stripe, Shopify, and British Airways underscore its growing market presence and credibility in the climate-tech sector (source: levels.fyi).
Recent Developments
In the last two years, Planetary Technologies has secured a prestigious XPRIZE Carbon XFactor award, which included approximately $1 million USD in funding, highlighting its innovative approach to carbon removal (source: betakit.com). The company completed a Series A funding round in October 2024 valued at about $11.35 million USD, bringing total funding to approximately $14.6 million USD from investors such as BDC, XPRIZE, Evok Innovations, DNX Ventures, Amplify Capital, and ICONIQ Capital (source: thecompanycheck.com). Concurrently, Planetary has been scaling its Halifax demonstration project by a factor of 10 annually over the past three years, moving from research and development toward commercialization and larger-scale carbon removal delivery (source: unreasonablegroup.com).
Working There
Planetary Technologies offers roles across ocean science, chemical and process engineering, environmental monitoring, software and data systems for measurement and verification, operations, partnerships, and internal business functions, reflecting its multidisciplinary climate-tech focus (source: xprize.org). The company operates primarily from its Dartmouth headquarters with an additional office in Ottawa, providing hubs for collaboration and innovation (source: linkedin.com). Publicly available information suggests a small, hands-on startup culture emphasizing collaboration with researchers, regulators, and local communities, with a "roll up your sleeves" attitude that encourages active engagement and problem-solving (source: lobbycanada.gc.ca). While specific employee benefits are not publicly documented, the company’s structured team and partnerships indicate a professional environment focused on impactful climate solutions (source: ccib.ca).
