What Gigablue does
Gigablue Ltd. is a marine carbon dioxide removal (mCDR) company founded in 2022 and headquartered in New York, with R&D origins in Israel and field operations in New Zealand. The company has pioneered the Microalgae Carbon Fixation and Sinking (MCFS) methodology, which deploys geo-specific engineered substrates to cultivate microalgae at the ocean surface and then sink the carbon-laden biomass to the deep ocean for permanent sequestration lasting hundreds to thousands of years. Supporting the core technology is an AI-powered oceanographic intelligence platform that optimizes deployment zones and substrate compositions using satellite imagery, in-situ sensors, ROV data, and oceanographic research, along with a custom-built deep-sea ROV (developed with Astral-Subsea) and a four-stage Measurement, Monitoring, Reporting, and Verification (MMRV) framework.
The company's revenue model is the sale of durable marine carbon removal credits, certified under the Puro.earth standard, to corporations, governments, and aviation/shipping buyers. Pricing is quote-based, structured around tons of CO2 removed and sequestered, and delivered via multi-year offtake agreements. Gigablue reached several commercial milestones in 2025–2026, including Puro.earth Advisory Board approval of the MCFS methodology in September 2025, a 200,000-tonne offtake with aviation-focused investor SkiesFifty, listing on the UG Group Carbon Plant exchange, and a $20 million Series A first close led by Planet Ocean Capital in January 2026. Operations are conducted under New Zealand EPA permits and London Convention/London Protocol compliance, with research partnerships across NIWA, Cawthron Institute, and Earth Sciences New Zealand providing independent scientific validation.

Gigablue product offering
Product offeringCore offering
Gigablue provides marine carbon dioxide removal (mCDR) services through its proprietary Microalgae Carbon Fixation and Sinking (MCFS) methodology. The company deploys engineered substrates in open-ocean HNLC (High-Nutrient, Low-Chlorophyll) zones to cultivate microalgae, which then sink to the deep ocean for permanent carbon sequestration lasting hundreds to thousands of years. Gigablue sells verified carbon removal credits (CORCs under the Puro.earth standard) to corporations and governments pursuing net-zero commitments, with multi-year offtake agreements priced per ton of CO2 removed.
Product overview
Gigablue is a marine carbon dioxide removal company offering a portfolio of interconnected products and services centered on its proprietary Microalgae Carbon Fixation and Sinking (MCFS) technology. The core offering is MCFS, an mCDR method that uses engineered substrates to cultivate phytoplankton which then sink to the deep ocean for permanent sequestration. Supporting the core product is an AI-powered Geo-Optimization Platform that identifies optimal deployment locations, and a Custom Deep-Sea ROV Monitoring system for ground-truth verification. Gigablue also provides MMRV (Measurement, Monitoring, Reporting, and Verification) services and sells Carbon Removal Credits (Carbon Futures) to corporations and governments.

Products and services
- Microalgae Carbon Fixation and Sinking (MCFS) Gigablue's proprietary marine carbon dioxide removal method that uses biogeochemistry to cultivate microalgae on engineered substrates, which then sink to the deep ocean for permanent carbon sequestration lasting hundreds to thousands of years. The methodology uses abundant natural inputs (sunlight, water, gravity) and is certified under the Puro.earth standard with a minimum 200+ year durability.
- Carbon Removals / Carbon Futures High-durability, verified marine carbon dioxide removal credits offered to corporations and governments seeking to reach net-zero, backed by Gigablue's MCFS methodology and Puro.earth certification framework. Credits are sold via direct enterprise sales, multi-year offtake agreements, and through the Carbon Plant exchange marketplace.

Gigablue competitors and assessment
Company assessmentOthers
- Puro.earth: Leading carbon removal certification standard under which Gigablue's MCFS methodology is certified. Ecosystem partner rather than direct competitor, but sets the bar Gigablue's methodology must meet for buyer acceptance.
Direct peers
- Captura: Marine CDR company using electrochemical ocean alkalinity enhancement to capture CO2 from seawater. Direct peer competing for the same enterprise CDR buyer segment as Gigablue with a different biogeochemical mechanism.
- Running Tide: Pioneered ocean-based carbon removal using macroalgae sinking and other marine CDR methods. Closest direct peer to Gigablue on marine CDR approach, though Running Tide wound down operations in 2024, validating both the opportunity and the execution risks Gigablue faces.
- Equatic: Ocean CDR company using electrolysis to remove CO2 from seawater and produce hydrogen as a byproduct. Direct peer in the marine CDR category with backing from a similar mission-aligned investor base and certified credit issuance.
- Ebb Carbon: Ocean alkalinity enhancement (OAE) company removing CO2 by adding alkalinity to seawater. Direct competitor in the marine CDR category targeting corporate offtake buyers with a different but adjacent removal pathway.
Broad incumbents
- Climeworks: Largest direct air capture (DAC) company with established offtakes from major corporations like Microsoft and Stripe. Broader CDR incumbent competing for the same corporate net-zero buyer demand but using a different (engineered, terrestrial-based) removal pathway.
- Charm Industrial: Leading biochar-based CDR company with major enterprise offtakes (Stripe, JPMorgan, Microsoft). Broader durable CDR incumbent providing competing removal pathway to Gigablue for corporate buyers prioritizing land-based verifiability.
- Heirloom Carbon: DAC company using limestone-based enhanced mineralization with major enterprise offtakes (Stripe, Klarna, Shopify). Broader durable CDR competitor with similar Puro.earth certification and corporate buyer pipeline as Gigablue.
Emerging players
- Vesta: Coastal carbon removal company using olivine mineralization on beaches and coastlines. Emerging peer operating in adjacent marine-adjacent CDR space with overlapping buyer segments.
- Planetary Technology: Early-stage ocean alkalinity enhancement company focused on basalt-based CDR approaches. Emerging competitor in marine CDR with partial technology overlap on ocean-based removal pathways.
