What they do.

Ocean Balance is developing marine carbon-removal technology with the potential for lasting, gigatonne-scale CO₂ removal. The approach uses ocean chemistry to permanently sequester atmospheric carbon. The CO₂ is removed from the atmosphere and stored in the ocean in a form that remains stable across thousands of years.

The work is at the laboratory and pilot-trial stage. The company is developing the deployment hardware, monitoring approach, and verification protocols in parallel.

Why it matters.

Permanent carbon removal at gigatonne scale is the missing piece of credible climate action. Emissions reduction alone is not enough to stabilise atmospheric CO₂ at safe levels; permanent removal is required. Most current carbon-removal approaches struggle on durability, on scale, on cost, or on all three.

The ocean is the largest natural carbon sink on the planet. Working with ocean chemistry to enhance permanent storage is one of the few credible pathways to truly large-scale removal. The voluntary carbon market is already pricing durable removal in the hundreds of dollars per tonne; the eventual market for verified, permanent removal will be measured in the trillions.

Where they are now.

  • Laboratory trials underway, validating the chemistry and monitoring approach.
  • First marine trials planned late 2026 to early 2027.
  • Engaging carbon-removal buyers and verification bodies in parallel with the science development.
  • Capital deployment supports the trial programme, monitoring instrumentation, and verification-protocol development.

The CVCF investment.

Climate Fund 1 backed Ocean Balance in the early-research phase. The thesis: durable, gigatonne-scale carbon removal is a structural requirement of any credible climate trajectory, and the market that emerges around verified removal will be vast. Ocean-chemistry approaches are among the few credible pathways to that scale.

Ocean Balance passed the Climate Impact Committee's IRIS+ review. Each verified tonne of carbon removed delivers permanent, additional impact, tied directly to the company's commercial output.
