"Containers full of quicklime could help clean up one of the world’s filthiest
industries.
Global shipping, which is fuelled predominantly by marine diesel, belches out
around 3% of planetary greenhouse gas emissions, making the sector a bigger
polluter than aviation.
Now, London-based startup Seabound has come up with a solution to help
freighters chart a course for net zero, with a surprisingly simple carbon
capture system. The lo-fi method involves funnelling ships’ exhaust fumes
through calcium oxide pebbles, also known as quicklime. They soak up the CO₂,
which leads to a chemical reaction that turns them into harmless limestone,
which can be safely stored or even sold for profit.
A three-week ocean-going trial showed that Seabound’s method can hoover up 78%
of a ship’s carbon emissions and 90% of toxic sulphur exhaust fumes.
The company’s latest prototype packs into a standard shipping container, making
it easy to install on cargo decks and swap out in port.
The big challenge now is scale: Seabound will need a steady supply of
sustainably produced quicklime. Traditional production methods are
energy-hungry, emitting significant emissions of their own."
