Uses ocean alkalinity enhancement to accelerate rock weathering, transforming CO2 into stable bicarbonates that are stored in the ocean for over 100,000 years. This process permanently removes atmospheric carbon while countering ocean acidification, protecting ecosystems like coral reefs and shellfish fisheries.

Problem
Rising atmospheric CO2 levels contribute to climate change and ocean acidification, threatening marine ecosystems and coastal communities. Traditional carbon capture methods are often energy-intensive and lack long-term storage solutions.
Solution
Ephemeral Carbon enhances natural rock weathering processes to permanently remove atmospheric CO2 and mitigate ocean acidification. The company extracts alkalinity from rocks and industrial wastes using renewable energy. This alkalinity is then released into the ocean, where it transforms dissolved CO2 into stable bicarbonates, effectively locking away carbon for over 100,000 years. This process also counteracts ocean acidification, protecting vulnerable ecosystems like coral reefs and shellfish fisheries. By accelerating a natural process, Ephemeral Carbon offers a scalable and environmentally beneficial approach to carbon removal and ocean restoration.
Target Audience
Ephemeral Carbon's primary customers are organizations seeking to offset their carbon emissions and support ocean restoration projects, including corporations, governments, and individuals committed to environmental sustainability.
