The world's first carbon-negative transportation

CO2Rail deploys a proprietary system powered by existing train regenerative braking energy to achieve both low-cost rail decarbonization [CCS] and rail-based Direct Air Capture [DAC] carbon removal by capitalizing and leveraging well-developed rail infrastructure and networks.

Two Primary Technology Offerings

CO2Rail's technology suite is comprised of two distinct but complementary carbon mitigation systems. Direct Air Capture [DAC] from ambient air and Carbon Capture and Storage [CCS] from diesel locomotive emissions.

Ambient Air DAC

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.

Diesel Exhaust CCS

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

Our Disruptive Advantage? ...Energy

The Opportunity

Every year, globally running trains, both diesel and electric, dissipate about 420 tWh of braking energy as rheostatic waste heat. This is more than all but 10 countries use annually, over 4x the annual output of the Three Gorges Dam in Chinia, and 105x the annual output of the Hoover Dam in the US.

Until now, this enormous amount of electrical energy has been wasted in most rail operations. CO2Rail uses it to power CO2 removal from both ambient air and emissions from diesel-powered trains.

CO2Rail is Unlocking Carbon-Negative Rail

Pre-Built Scalability

> 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.

Key Features

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

Best-in-class CAPEX

Lowest investment requirement to scale compared to other solutions. Our system uses the expansive infrastructure already in place with a global rail system that would reach to the moon and back twice over and with railcars that would circle the globe four times if put end-to-end.

Highest quality off-take guarantees

By leveraging economic value from the 45Q tax program and captur otherwise wasted energy,C2Rail is a low-cost method of rail operators to decarbonize
Expanding Icon

Low-cost method to decarbonize

Leverages currently wasted sustainable energy. By tapping into the train's wasted braking energy generated from already running trains moving freight and passengers, we are able to significant lower the cost of DAC, ultimately aiming for a cost of <$50/ton

Scalable approach

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

Modular & upgradable design

Our system is sorbent agnostic and provides a unique platform for a suite of DAC and CCS technologies, both existing and anticipated. Whether electro, temperature, pressure, humidity or other types of desorption, the CO2Rail platform can deploy at scale and is easily upgradable.

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
