Shipping is the backbone of the modern economy. At least 80% of all goods worldwide are shipped as ocean cargo, and the global economy rises and falls on the free movement of gigantic ships across the sea. But container ships and bulk carriers burn what’s known as bunker fuel, one of the dirtiest fossil fuels. The international shipping industry generates 3% of global carbon emissions, a proportion that’s projected to rise through the century.
Most proposals to decarbonize ocean freight have focused on using ammonia or other zero-carbon liquid fuels. But Fleetzero, a Bill Gates-backed startup, is trying to use the only technology that it says can get cheap enough to compete with oil: batteries. The Alabama-based company is building batteries big enough to hybridize — and, eventually, power outright — the world’s largest ships.
This week, Rob chats with Steven Henderson, the cofounder and CEO of Fleetzero and a graduate of the U.S. Merchant Marine Academy. They talk about Steven’s history in the oil and gas industry, why batteries will beat liquid fuels, and how to put out a fire in the middle of the ocean.
