I came across this interesting, London-based carbon capture start-up today. Their focus is on the container ships that spew more greenhouse gases into the atmosphere than planes.
Their proposed technology “works by routing the exhaust into a container that’s filled with porous, calcium oxide pebbles, which in turn “bind to carbon dioxide to form calcium carbonate,”— essentially limestone.”
Readers who are fellow climate nerds, would love to hear your thoughts on this!
