Remora

Remora’s devices capture carbon emissions directly from truck tailpipes. They can be fitted onto tailpipes of existing trucks to capture carbon dioxide (CO2) for 600–1,200 miles before an offload. Remora’s solution was initially funded by the Environmental Protection Agency (EPA) and tested at the agency’s National Vehicle and Fuel Emissions Lab.

The company’s technology has a capture efficiency of 80% and can offload the captured CO2 while refueling—to be sold to concrete producers and other end users. The proceeds from the sale of CO2 are expected to be shared across fleet owners and customers once commercialized.

Funding and financials

In February 2024, the company raised an undisclosed amount in a Series A funding round led by Voyager Ventures.
