Paul Gross and his team at Remora are trying to do something that’s never been done before. They’re building mobile carbon capture devices for commercial trucks and trains. It’s a system that captures CO2 from moving vehicles before those emissions ever enter the atmosphere. Then they turn those captured emissions into revenue by selling to customers that can turn the liquified CO2 into new products.

In this episode of Hard Tech, YC’s Gustaf Alströmer visited Remora’s headquarters outside of Detroit to find out how a recent college graduate with no engineering background is helping transform the $2 trillion transportation industry.

  1. So the gain to the climate is that the companies carbonating soda do not have to derive their Co2 for the carbonation from new fossil fuel, instead they can re-use Co2 from already emitted sources?
    This is a cool product for sure!
    But it doesn't adress the problem of new carbon being released into the atmospehe from non-renewable resources.
