What Planetary does

Planetary Technologies is a Dartmouth, Nova Scotia-based climate company founded in 2019 that performs coastal carbon dioxide removal through Ocean Alkalinity Enhancement (OAE). The company introduces purified alkaline minerals — primarily magnesium hydroxide, and more recently calcium byproducts — into the outfalls of existing coastal infrastructure such as power plants and wastewater treatment facilities, boosting seawater's buffering capacity so that atmospheric CO2 converts into stable bicarbonate ions for permanent (100,000+ year) storage while reducing local ocean acidity. The product surface is the Ocean Carbon Platform (OCP), which bundles three modules: a pure-alkalinity supply chain, a modular site automation and monitoring hardware unit (tanks, sensors, pumps, dosing system), and project software for real-time monitoring, ocean modeling, and carbon removal verification. The independently reviewed Measurement, Reporting, and Verification (MRV) protocol, developed with carbon registry Isometric, has been used to issue the world's first verified OAE carbon credits. Operational pilots are running at Nova Scotia Power's Tufts Cove Generating Station (Halifax, since September 2023, with over 4,853 tonnes of CO2 removed cumulatively) and at the Elizabeth River Project in Virginia (world's first calcium-byproduct dosing pilot, 2025).

Planetary generates revenue through the sale of independently verified carbon removal credits negotiated via multi-year offtake agreements with large corporate buyers. The model is transaction-based: customers prepay for future verified removes. The $31.3 million Frontier offtake agreement (2025), covering 115,000 metric tons of removal between 2026 and 2030, is the largest OAE deal ever signed and represents the bulk of contracted forward revenue; the Frontier coalition backing it includes Google, Stripe, Meta, Shopify, and McKinsey. Earlier customers include Shopify (first customer, via its Sustainability Fund), Stripe, British Airways (purchased the world's first verified OAE credits), Google, and H&M. The company has also received a $1 million Elon Musk Foundation prize through the XPRIZE Carbon Removal competition (April 2022), government grants from Canada and the UK (March 2022), and an $11.35 million institutional round led by Evok Innovations (October 2024) with BDC Venture Capital, DNX Ventures, Iconiq Capital, and Amplify Capital. Total disclosed funding is approximately $20 million. Go-to-market is exclusively direct enterprise sales to large corporate sustainability buyers; there are no consumer or reseller channels. Pricing is not publicly disclosed but implied at roughly $272 per ton based on the Frontier offtake, with a stated cost trajectory from over $2,000/ton in R&D toward below $250/ton within the decade and below $100/ton at full scale.

Revenue model

1. Carbon Removal Credits (Offtake Agreements): Company sells carbon removal credits to customers via upfront offtake agreements. Customers pay in advance for future carbon removal deliveries. Examples include $31.3M Frontier offtake for 115,000 tons CO2 removal (2026-2030), and early purchases from Shopify, Stripe, and British Airways. Revenue is transaction-based, with credits generated upon verified carbon removal.
2. XPRIZE and Grant Funding: Company received $1 million prize from the Elon Musk Foundation as part of the XPRIZE Carbon Removal competition in April 2022. Additional funding from UK government grants for project exploration.

Core offering

Planetary delivers permanent ocean-based carbon dioxide removal through its Ocean Carbon Platform, which packages ocean alkalinity enhancement (OAE) capabilities for deployment at coastal infrastructure sites. The platform combines purified alkaline mineral dosing, automated site hardware, project software, and an independently reviewed MRV protocol to convert atmospheric CO2 into stable bicarbonate via seawater restoration.

Product overview

Planetary's product portfolio centers on the Ocean Carbon Platform as the core product, which provides everything necessary to deploy safe ocean alkalinity enhancement (OAE) projects. This platform is complemented by Site Automation and Monitoring Hardware (the alkalinity dosing system with tanks, sensors, and pumps) and Project Software (for monitoring, modelling, and MRV). Together, these modules enable operators to neutralize seawater acidity and remove CO2 from the air safely. The company generates revenue through the sale of independently verified carbon removal credits, with key customers including Shopify, Stripe, British Airways, and deals with Frontier (backed by Google and Meta).

Broad incumbents

• Charm Industrial: California-based biomass carbon removal and storage company that pyrolyzes biomass and injects the resulting bio-oil underground. Competes for Frontier and corporate offtake commitments within the engineered CDR category.
• Climeworks: Swiss/ Icelandic direct air capture leader and one of the most capitalized CDR companies globally. Broad incumbent in engineered CDR, competing for the same corporate buyer offtake dollars though with a different (DAC-based) technology pathway.
• Heirloom Carbon: California-based DAC company using limestone-based direct air capture. Comparable to Planetary as a venture-backed engineered CDR developer pursuing Frontier offtakes and corporate CDR customers, though using a mineral-based rather than ocean-based approach.

Regional players

• CarbonCure Technologies: Nova Scotia-headquartered company that injects captured CO2 into concrete during mixing for permanent mineralization. Same regional ecosystem and overlapping climate-tech investor base as Planetary, with a complementary (concrete-based) mineral carbonation pathway.

Direct peers

• Ebb Carbon: US-based Ocean Alkalinity Enhancement company developing electrochemical OAE technology. Most direct competitor to Planetary in the OAE category, pursuing a similar end market (corporate CDR buyers) with comparable coastal pilot deployments.
• Captura: California-based OAE company using direct ocean capture with electrochemical alkalinity extraction. Competes head-to-head with Planetary in the OAE category, sharing corporate buyers and pursuing similar gigaton-scale ambitions.
• Vycarb: Dutch OAE startup developing technology to measure and enhance ocean alkalinity uptake. Direct OAE category peer, sharing the same buyer coalition (Frontier) and competing for coastal deployment sites in Europe.

Emerging players

• CarbonCapture Inc. California-based DAC company developing modular solid sorbent direct air capture systems. Comparable emerging CDR peer pursuing gigaton ambitions and corporate buyer offtakes, with overlapping capital providers.
• Carbfix: Icelandic company that mineralizes captured CO2 into basalt rock formations. Adjacent carbon removal peer sharing the broader mineral-based CDR thesis with Planetary's alkalinity approach and overlapping science/regulatory networks.
• Gigablue: Singapore-headquartered ocean CDR company pursuing OAE alongside seaweed-based and other ocean-based pathways. An emerging player in the broader marine CDR space overlapping with Planetary's end markets.
