Clean Air Power says that the UK trials, which used the Genesis Dual-Fuel™ retro-fit system, demonstrated a 50 percent gas substitution and a CO2 saving of 8.4 tons a year, based on 200,000km annual mileage. The lowered gas usage could save operators about £10,000 per vehicle per year in fuel costs).
Compare this to a contemporary integrated system, which can deliver about 70 percent overall gas substitution (saving £17,000 per vehicle per year) and cut out 26 tons of CO2 a year (based on the same annual mileage).
Clean Air Power says that over 1,600 vehicles around the world have been set up with the retro-fit system, and they are actively looking for an OEM to come to them with an offer to build an integrated system, said CEO John Pettitt.
Caterpillar has designed a similar diesel and natural gas system for use in its large vehicles.
