SYDNEY, Australia – Mankind are in a desperate race to halt our rampant carbon emissions and save the planet from our self-created catastrophe. Some of the most prominent technologies helping us achieve this venture are EVs and hydrogen fuel cells.
But due to cost and a slow adoption speed, these technologies have yet to significantly reduce our overall emissions. Fortunately, Australian researchers may have just created a near-perfect bridging technology that can easily convert diesel engines into super-efficient carbon-neutral machines! But how have they done this? And could this cause a carbon-neutral revolution?
Researchers from the University of Sydney have retrofitted a diesel engine to run off 90% hydrogen. This, in turn, has reduced emissions by 85% to only 90g per kWh and has increased engine efficiency by a massive 26%! The oil-derived part of the fuel can easily be swapped out for biofuel with only minor modifications, enabling this engine to run entirely carbon neutrally. Furthermore, this engine doesn’t require high-purity hydrogen and can run off cheaper, easier-to-produce low-purity hydrogen.
But how does this engine work? And why is it better than a pure bio-diesel engine or a pure hydrogen combustion engine? Well, for three reasons: NOx emissions, efficiency, and supply chain reliability.
