Transport Invention that can capture carbon from ship decks

An industrial park alongside the River Lea in the London suburb of Chingford is not the most obvious place for a quiet revolution.

But there, a team of entrepreneurs are tinkering with a modest-looking steel container that could clean up one of the world's dirtiest industries.

Inside it are thousands of cherry-sized pellets made from quicklime. At one end, a diesel generator pipes fumes through the lime, which soaks up the carbon, triggering a chemical reaction that transforms it into limestone.

With this, Seabound hopes to capture large amounts of carbon directly from the decks of cargo ships and help clean up a strikingly polluting industry. More than 50,000 cargo ships are at sea at any moment, producing 3% of global greenhouse gas emissions - more than aviation.

Behind Seabound is Alisha Fredriksson, a young entrepreneur who dreamed of being a doctor but changed course after reading a report from the Intergovernmental Panel on Climate Change about the implications of global heating.
