The CryoPower Cool Combustion process enables recovery of otherwise wasted exhaust heat which is then cooled via the injection of a small amount of liquid nitrogen. The liquid nitrogen acts as both a coolant and an additional source of energy, reducing emissions and improving fuel efficiency.
Test results, carried out as part of the StepCO2 programme part funded by the UK’s innovation agency, Innovate UK, have shown CryoPower to offer a near-zero emissions capability, in some cases offering lower tailpipe NOx emissions than in the surrounding air and with potential to remove pollution in towns and cities.
CryoPower was originally conceived as a means of enabling otherwise unachievable improvements in fuel economy and reduced CO2, targeted at achieving at least 60 percent brake thermal efficiency. The early development work carried out on the test rig installed at the University of Brighton has not only validated this potential but has also demonstrated the highly impressive low-NOx emissions credentials of the CryoPower combustion process.
