Exciting news! Our cover highlighted Joule paper, "RAIL-BASED DIRECT AIR CARBON CAPTURE", is now open access and available for download. The paper highlights the significant impact that CO2Rail will have in removing gigatons of CO2 through DIRECT AIR CAPTURE (DAC) which is self-powered by LOCOMOTIVE REGENERATIVE BRAKING. A tremendous source of sustainable energy that currently goes to waste in most trains. ACCESS THE PAPER HERE: https://lnkd.in/gTDBHv6k #DirectAirCapture #Innovation #Climate

If the train is outfitted with the appropriate number of Direct Air Capture cars that available regenerative braking energy will support, most freight and passenger trains will be significantly carbon negative. The exact CO2 removal tonnage will vary by the speed, weight, route, average slope of the line, and even factors such as ambient air temperature, and humidity. Overall, the average large North American diesel freight train could achieve somewhere in the neighborhood of —40+ t/co2e/day in emission after the diesel emissions are about ~70% mitigated with similar appearing CCS cars and the resulting net emissions accounted for. Results are much higher on electrified lines because all the attached CO2Rail cars (and available regenerative braking energy) can be exclusively dedicated to negative emissions Direct Air Capture operations.

This is very cool. Does this lead to negative emissions for the train? Is there any end product associated with the carbon capture?
