Making waves with marine carbon capture

The global shipping industry emits ~1 billion tonnes of carbon dioxide annually, about as much as the sixth highest emitting nation in the world. In hopes of changing course, the International Maritime Organization (IMO) has mandated that starting in 2023, most commercial vessels will have to document their CO2 emissions, and demonstrate progress towards reaching the IMO objective of an industry-wide 40% reduction in emissions by 2030.

But that is easier said than done. As we learned in earlier conversations on maritime shipping (here and here), low-emission alternatives to the cheap and extremely dirty bunker fuels that ships currently use are far from ready to deploy at scale. So what can ship owners do to start cutting their emissions as soon as next year?

We spoke with Co-founder and CEO of the start-up Seabound, Alisha Fredriksson, about her teams' proposed solution: equipping ships with carbon capture devices that trap and store CO2 from fuel exhaust. The CO2 can be brought to port and either sold for CO2 utilization projects, or permanently stored underground. Learn more about how their technology works and their business case for why it is a good idea to get onboard with carbon capture.
