It is then transported into the circular carbon economy as value-added feedstock for CO<sub>2<\/sub> utilisation, or to nearby geological landfill sites.&nbsp;<\/p>\n\n\n\n<p>Each of these processes are powered exclusively by on-board generated, sustainable energy sources that require no external energy input or off-duty charging cycles.<\/p>\n\n\n\n<p>When a train pumps the brakes, its energy braking system converts the train\u2019s forward momentum into electrical energy in much the same way as a regenerative electric vehicle. Currently, this energy is dissipated on trains in the form of heat and discharged out of the top of the locomotive during every braking manoeuvre.<\/p>\n\n\n\n<p>The direct capture of carbon dioxide from the environment is increasingly becoming an urgent necessity to mitigate the worst effects of climate change.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p><strong>Co-author of the research, Professor Peter Styring from the University of Sheffield&#8217;s&nbsp;Department of Chemical and Biological Engineering and Director of the UK Centre for Carbon Dioxide Utilization, said:&nbsp;<\/strong>\u201cCurrently the enormous amount of sustainable energy created when a train brakes or decelerates is simply lost. This innovative technology will not only use the sustainable energy created by the braking manoeuvre to harvest significant quantities of CO<sub>2<\/sub>, but it will also take advantage of many synergies that integration within the global rail network would provide.<\/p><p>\u201cThe technology will harvest meaningful quantities of CO<sub>2<\/sub> at far lower costs and has the potential to reach annual productivity of 0.45 gigatons by 2030, 2.9 gigatons by 2050, and 7.8 gigatons by 2075 with each car having an annual capacity of 3,000 tonnes of CO<sub>2<\/sub> in the near term.\u201d<\/p><\/blockquote>\n\n\n\n<p>Unlike stationary DAC operations, which require large areas of land to build equipment and to construct renewable sources of energy to power them, CO2Rail would be transient and would generally be unseen by the public. The potential impact of this technology was recently energised when European transport organisations announced earlier this month that they are committed to tripling high-speed rail use by 2050 to curb CO<sub>2<\/sub>-heavy air travel.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p><strong>Eric Bachman of CO2Rail Company, said:<\/strong>&nbsp;\u201cOn average, each complete braking manoeuvre generates enough energy to power 20 average homes for an entire day so it is not a trivial amount of energy.&nbsp;<\/p><p>\u201cMultiply this by every stop or deceleration for nearly every train in the world and you have about 105 times more energy than the Hoover Dam produces within that same period, and that was a hydro-electric construction project that took six years and cost $760 million in today\u2019s dollars.\u201d<\/p><p><strong>He added:<\/strong>&nbsp;\u201cImagine stepping onto a train each morning, seeing the CO2Rail cars attached, and knowing that your commute to work each day is actually helping to mitigate climate change.<\/p><p>\u201cIt will work the same with freight, if there is a choice between rail and another mode of transportation, I think this technology will sway many shippers.\u201d<\/p><\/blockquote>\n\n\n\n<p>The team, which includes researchers from the University of Sheffield, University of Toronto, MIT, Princeton, business, and industry, found each direct air capture car can harvest about 6,000 metric tons of carbon dioxide from the air per year and more as the technology develops. Moreover, since trains are capable of hosting multiple CO2Rail cars, each train will harvest a corresponding multiple of CO<sub>2<\/sub> tonnage.&nbsp;<\/p>\n\n\n\n<p>With its sustainable power requirements exclusively supplied by train-generated sources that are without incremental cost, savings of 30 \u2013 40 per cent per tonne of harvested CO<sub>2<\/sub> can be realised from energy inputs alone.&nbsp;<\/p>\n\n\n\n<p>This, along with other significant savings such as land, brings projected cost at scale down to less than $50 per tonne and makes the technology not only commercially viable but commercially attractive.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p><strong>Professor Geoffrey Ozin from the University of Toronto and co-author of the study, said<\/strong>: \u201cAt these price points and with its tremendous capabilities, CO2Rail is likely to soon become the first megaton-scale, first gigaton-scale, and overall largest provider of direct air capture deployments in the world.<\/p><p>\u201cCarbon-neutral in regular transportation and then significantly carbon-negative with ambient air DAC operations. A win-win in every respect and a \u2018save humanity\u2019 technology.\u201d&nbsp;<\/p><\/blockquote>\n\n\n\n<p>The team is also working on a similar system that can remove the CO<sub>2<\/sub> emissions from the exhaust of diesel-powered locomotives as are universally common in North America and other parts of the world.
