Carbon Kapture

What Carbon Kapture does

Carbon Kapture is a private direct-to-consumer company founded in 2020 that sells ocean-based carbon removal through kelp cultivation. The company deploys seaweed rope infrastructure in coastal waters where kelp grows naturally through photosynthesis, absorbing CO2 and storing carbon in biomass. Kelp is positioned as absorbing CO2 up to 40 times faster than land-based plants while requiring no freshwater, fertilisers, or arable land. The company's primary operational site is Mulroy Bay, Ireland, with planned expansion to Scotland and England.

The core product offering consists of four tiers: three monthly subscriptions (Starter Seaweed at £10/month for 5 metres deployed, Impact Seaweed at £40/month for 20 metres, and Legacy Seaweed at £200/month for 100 metres) and a one-time purchase option at £25 per metre. All purchases are processed through Stripe on the company's website. The company reports over 10,000 units sold across each tier, targeting environmentally conscious individuals — particularly surfers and ocean enthusiasts — through community-driven outreach and word-of-mouth marketing.

Carbon Kapture operates with a lean team of 5 employees and a leadership group consisting of Howard Gunstock (CEO), Dave Walker-Nix (CTO), Paul Rees (CRO), and Krishna Patel (CFO). The company has no disclosed funding rounds, patents, partnerships, or enterprise customers. Revenue figures are not publicly disclosed. The business model is entirely retail/consumer-facing, with global website sales and no B2B or corporate carbon credit sales channels identified.

Revenue model

1. Seaweed Deployment Subscriptions: Monthly subscription model where customers sponsor metres of seaweed rope deployment in coastal waters. Customers receive carbon capture impact in exchange for recurring payments. Subscription tiers range from £10/month (5m) to £200/month (100m).
2. One-Time Seaweed Purchases: One-off payment option for purchasing seaweed rope deployment at £25 per metre. Customers make a single contribution without ongoing commitment.

Core offering

Carbon Kapture operates subscription-based sponsorships of kelp (seaweed) rope deployment in coastal waters for ocean-based carbon capture. Customers fund metres of kelp rope that grow seaweed through natural photosynthesis, absorbing CO2 and supporting marine ecosystem restoration. The portfolio comprises three monthly subscription tiers and one one-off purchase option, all transacted through a Stripe-powered e-commerce checkout on the company website.

Product overview

Carbon Kapture operates a subscription-based seaweed rope deployment platform where individual supporters can fund metres of kelp growth in coastal waters for carbon capture and ocean ecosystem restoration. The product portfolio comprises four offerings: three monthly subscription tiers (Starter Seaweed at 5m for £10/month, Impact Seaweed at 20m for £40/month, and Legacy Seaweed at 100m for £200/month) plus a one-time purchase option (Choose Your Amount at £25 per metre). All offerings fund physical infrastructure that absorbs CO2 through natural kelp photosynthesis while restoring marine habitats. The company currently operates in Ireland (Mulroy Bay) with plans to expand to Scotland and England.

Products and services

• Starter Seaweed Entry-level monthly subscription enabling individual supporters to fund 5 metres of deployed seaweed rope for £10 per month, providing a simple introduction to ocean-based carbon capture and marine ecosystem restoration.
• Impact Seaweed Mid-tier monthly subscription supporting 20 metres of deployed seaweed rope for £40 per month, positioned as the best balance of environmental impact and value for sustained carbon capture support.
• Legacy Seaweed Premium monthly subscription funding 100 metres of deployed seaweed rope for £200 per month, designed for supporters seeking lasting environmental legacy through large-scale ocean-based carbon capture.
• Choose Your Amount Customisable one-time purchase option allowing supporters to specify exactly how many metres of seaweed rope to deploy into the ocean at £25 per metre, with no recurring commitment.

Others

• Pachama: Pachama operates a marketplace and verification platform for nature-based carbon credits including forestry and blue carbon. It is an adjacent ecosystem participant that could either be a distribution partner or competitive threat for credit sales.

Direct peers

• Kelp Blue: Kelp Blue cultivates giant kelp offshore in Namibia for carbon sequestration and biobased products. It is the closest direct peer—both companies use large-scale kelp farming to deliver ocean-based carbon removal plus downstream biomass revenue.
• SeaForester: SeaForester restores and cultivates seaweed forests in European waters, including commercial-scale kelp farming with co-benefits for marine ecosystems. Comparable to Carbon Kapture in its focus on kelp-based restoration and carbon removal in temperate coastal waters.
• Running Tide: Running Tide was a direct ocean-based carbon removal peer using kelp and macroalgae sinking for durable sequestration. (Note: the company wound down operations in 2023 but its model and competitive set are instructive for the category Carbon Kapture competes in.)
• Project Vesta: Project Vesta accelerates ocean alkalinity using olivine to enhance ocean CO2 uptake. It is a direct peer in the ocean-based carbon removal category, pursuing durable sequestration via marine chemistry.

Emerging players

• CH4 Global: CH4 Global farms Asparagopsis seaweed at scale to deliver livestock-feed methane reduction. It is comparable as a commercial seaweed aquaculture operator pursuing climate outcomes, though its end-product is methane reduction rather than direct CDR.
• Eion Carbon: Eion Carbon applies enhanced rock weathering on agricultural land for carbon removal credits. It is an emerging CDR peer with similar subscription/credit-based commercial models targeting voluntary market buyers.

Broad incumbents

• Climeworks: Climeworks is a leading direct air capture (DAC) provider selling carbon removal credits to corporate buyers. It is a broad incumbent in the durable CDR market and a relevant comparable for pricing, MRV standards, and corporate offtake dynamics.
• Heirloom Carbon: Heirloom uses DAC plus limestone-based mineralisation to deliver permanent carbon removal. It is a relevant broad incumbent for benchmarking premium durable-CDR pricing and customer mix.
• Charm Industrial: Charm Industrial converts biomass into bio-oil for permanent geological sequestration. It is comparable as a biomass-based durable CDR competitor pursuing corporate offtake contracts.
