identification "Possible and unexpected key" To reduce carbon emissions!

A US startup called CO2Rail Company is working with engineers from the University of Sheffield and the University of Toronto to develop massive air vents that suck in air as a train moves.

The carbon dioxide can then be separated from the air, turned into a liquid and stored inside the vehicle where it can be disposed of.

The researchers believe that this is more cost-effective than other DAC solutions because cars can be converted to trains that are already running.

This technology requires less land than fixed DAC facilities and will help countries achieve net zero emissions targets.

Professor Peter String, Director of the UK Carbon Dioxide Center at the University of Sheffield and co-author of the study, said: “Direct carbon sequestration from the environment is becoming increasingly important to mitigate the worst effects of climate change. technologies will gain up to 0.45 tons by 2003, 2.9 gigaton by 2050 and 7.8 gigaton by 2075.

In a research article published in JouleIn this paper, the researchers defined the design of CO2Rail vehicles. This is an example of DAC technology, which removes carbon dioxide from the air and compresses it for storage or use.

When the CO2-equipped car is moving, the air that rises in the sliding stream forces ambient air into the cylindrical CO2 collection chamber.

The air is then transported through a chemical process that separates the carbon dioxide before the carbon-dioxide-free air enters the rear or bottom of the car into the atmosphere.

After sufficient CO2 has been captured in the collection chamber, it is concentrated and stored in a liquid reservoir.

Fluid can be drained from a train at a crew change or when fuel is stopped for transportation to the circular carbon economy or to nearby geological dumps.

Each of the operations inside the CO2Rail vehicle is powered exclusively by existing solar panels or energy generated by the regenerative braking system.

When regenerative braking is applied, the current reverses to the electric motors and begins to convert the forward momentum of the vehicle into electrical energy.

In modern electric trains, this energy is dissipated as heat and expelled from the top of the locomotive during each braking maneuver.

Each complete braking maneuver generates enough energy to power 20 average houses a day, so we’re not talking about a tiny fraction of the energy.

Researchers say that an average freight train with CO2Rail wagons can remove up to 6,000 tons of carbon dioxide per year.

Stationary DAC technologies also use large, energy-intensive fans to supply air to them to capture carbon.

Purpose-built train cars eliminate the need for them because they use large vents to absorb air as they move.

Each trolley can also be retrofitted to existing rail systems, greatly reducing any potential installation costs.

Since sustainable energy needs are supplied internally, the price per ton is also significantly lower than other DAC systems.

The researchers hope the technology will encourage more passengers to use the railroad, thereby creating a positive feedback loop for decarburization.

The team, which also includes researchers from the Massachusetts Institute of Technology and Princeton, is working on a similar system that could remove carbon dioxide emissions from diesel locomotive exhaust instead of electricity.

With the rise of clean energy railway electrification systems, the point source capabilities of diesel lines will make railways the world’s first carbon-neutral mode of large-scale transportation.
