A team of engineers at the University of New South Wales (UNSW) in Sydney has figured out a way to run a diesel engine on a mix of diesel and hydrogen, dramatically lowering its emissions.
Why do we even need a diesel-hydrogen hybrid engine when there are already many great electric vehicles available? EVs are definitely great for households, but they still don’t match heavy diesel engines’ performance in some contexts, such as mining, long-distance transportation, power generation, and agriculture.
At present, there are 26,000 trains in the US that run on diesel, and there are potentially millions of trucks, generators, and other industry-grade equipment that require diesel to deliver optimum performance. It might take decades for EV technology to replace diesel engines in such industries. While it’s easy for a normal person to sell an old car and buy a new EV, such changes come at a high cost to industries.
