The world's first carbon-negative transportation

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

Ambient Air
DAC

Diesel Exhaust
CCS

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.

Our proprietary LETA (Locomotive Exhaust Transfer Array) and Carbon Capture and Storage (CCS) system can effectively capture up to 70% of of a diesel locomotive’s exhaust.

The opportunity

Train Braking at Night

Dynamic Brake Resistor Grids

Almost every freight and passenger train in the world already utilizes energy braking and has since the 1970s. Just like in EVs and hybrid cars, the forward kinetic energy of the train is converted into electrical energy during a braking event. In rail, this energy braking system is known as "Dynamic Braking" and utilizes larges banks of resistor grids and fans that literally burn off the substanial amount of electricity that is produced during each braking manuever.

For over 50 years, this enormous amount of energy has been wasted in rail operations. CO2Rail uses it to power carbon removal processes and remove CO₂ from both ambient air and emissions from diesel-powered trains.

Globally, trains dissipate ~700 tWh/year of braking energy electricity as waste heat, which is more than all but 5 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.

> 1 GT CO₂

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. Utilizing infrastructure already in place allows CO2Rail to scale at a pace like no other solution.

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

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

Leverages existing infrastructure

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

Best use case for train RBE

Compared to alternative uses of the wasted braking energy, such as additive propulsion, CO2Rail is over 5X better at carbon mitigation
