This Startup Is Trying To Delete 29% Of All CO2 Emissions

Remora CEO Paul Gross is building the world’s first mobile carbon capture systems for semi-trucks and freight trains, targeting 29% of all US CO2 emissions.

• Transportation is the largest US emissions sector at 29% of all CO2; trucks and trains are hardest to electrify.
• Remora’s device captures up to 90% of CO2 from semi-truck exhaust and produces beverage-grade liquid CO2 sold to food, beverage, and water treatment companies.
• For trains, Remora builds a dedicated rail car that attaches to the locomotive exhaust stack; they bought a 4,400 HP GE locomotive as a test pilot.
• Raised $17M in venture funding; signed evaluation agreements with Ryder and Union Pacific.
• Direct air capture is far less efficient: atmosphere is only 0.04% CO2, making it more energy-intensive and expensive than point-source capture.
• US emits 375 million tons of CO2 per year from trucks and trains, yet faces a domestic CO2 shortage that breweries and food companies feel directly.
• Remora’s long-term target is 1 billion tons of CO2 captured per year; technology also applicable to ships, cement plants, refineries, and generators.
