A NINE-month project which received almost £400,000 of First of a Kind competition funding from the Department for Transport last year has successfully shown that an existing Class 66 locomotive engine can be run on a ‘dual fuel’ mix of diesel and gas.
During load bank testing of Class 66 No. 66599 at Freightliner’s Leeds Midland Road depot, a precision injection system developed by Clean Air Power was used to substitute 30% of the EMD 12-710 power unit’s diesel intake with hydrogen. A diesel and biomethane mix can also be used.
