Launch HN: Remora (YC W21) – Carbon capture for semi trucks

Hi HN! I'm Paul, one of the co-founders of Remora ( https://remoracarbon.com ). Remora is building a device that captures the carbon emissions from a semi truck. Our device mounts between the truck and its trailer, attaches to its tailpipes, and captures at least 80% of its carbon emissions. We will sell the captured carbon dioxide to concrete producers and other end users, helping companies earn new revenue while meeting their climate commitments. We decided to start Remora because we believe electrification won't work for long-haul trucking. Bill Gates agrees: “Even with big breakthroughs in battery technology,” he wrote, “electric vehicles will probably never be a practical solution for things like 18-wheelers" [1]. Before Remora, my co-founder, Eric, built hydrogen and electric semi trucks. He saw first hand that these trucks have far less payload capacity and range, plus the batteries lose > 40% of their range in cold weather [2]. We also knew that elec
