Company Overview
Seabound is a UK-based climate technology company founded in 2021 that develops carbon capture equipment for the shipping industry. The company's solution is designed to be retrofitted onto existing ships, capturing up to 95% of CO2 emissions from the vessel's exhaust. The technology uses a process called calcium looping, where exhaust gases react with calcium oxide (quicklime) pebbles, converting the CO2 into solid calcium carbonate (limestone) pebbles. These pebbles are stored onboard and can be offloaded at port for sale, utilization (e.g., in cement production or creating new fuels), or sequestration. Seabound has completed successful pilot projects with major shipping companies like Lomar Shipping, Hapag-Lloyd, and Hartmann Group. The company is backed by venture capital firms such as Lowercarbon Capital and Y Combinator, and has also received significant grant funding from the UK government. Commercial deliveries of its full-scale systems are planned from 2025.
