Decarbonizing the world with rail

CO2Rail leverages a proprietary system powered by regenerative braking technology to achieve both low-cost rail decarbonization and rail-based carbon removal by capitalizing on existing infrastructure.

The problem

Globally, trains dissipate ~350 tWh/year of braking energy as waste heat, which is more than all but 10 countries use annually.  

Currently, the rail industry is on track to emit 85Mt+ CO2 annually, but options to decarbonize – like electrification and hydrogen – will require significant infrastructure investments and time to scale.

removals possible

CO2Rail has the potential to achieve a Gigaton scale of carbon removal annually if just 50% of the world’s wasted train braking energy was leveraged for Direct Air Capture.

Our solution

CO2Rail

CO2Rail is comprised of two complementary systems:

Diesel Exhaust CCS
Ambient Air DAC
Our Carbon Capture and Storage (CCS) system can effectively capture up to 70% of of a diesel locomotive’s exhaust.
Our Direct Air Capture (DAC) system can sit in any configuration on a train and uses energy from a regenerative braking system to capture carbon from ambient air.

Key features

Money Icon
Low-cost method to decarbonize

By leveraging economic value from the 45Q tax program and capturing otherwise wasted energy, CO2Rail is a low-cost method of rail operators to decarbonize

Expanding icon
Modular & scalable approach

Operators can scale our solution as far and wide as they need – tacking on additional railcars as needed to decarbonize their operations

Gears Icon
Leverages existing infrastructure

Implementing CO2Rail requires only minor adjustments to a locomotive's system and operations – making it an effective short-term decarbonization method

Carbon footprint icon
Optimal method for reducing carbon footprint

Compared to alternative uses of the wasted braking energy, such as propelling the train, CO2Rail is most effective and can uniquely enable the train to become carbon net-negative
