Cars annually emit a huge amount of carbon dioxide into the environment. At the same time, 40% of harmful emissions are from freight transport. Researchers have proposed a new system that reduces truck emissions by 90%.
Scientists at the Swiss Federal Institute of Lausanne (EPFL) have developed a new concept for capturing carbon dioxide from truck exhaust pipes. The essence of the idea is to turn carbon dioxide into a liquid even before it leaves the exhaust pipe of a car. To do this, it is proposed to cool the gases, separating carbon dioxide from nitrogen and oxygen. After that, carbon dioxide will go into a special tank where it can be taken to service stations.
Subsequently, liquid gas is proposed to be used as fuel. The only drawback of the technology was its bulkiness. So, the unit for converting carbon dioxide into liquid and the capsule for its storage occupy 2 meters in length and weigh 7% of the payload of the machine. This eliminates the installation of the system on cars.
Currently, this is just a concept, and its implementation will take years. Researchers are now developing a prototype system for testing experimental elements in practice.
