overnment policy should focus more on the well-to- wheel (WTW) greenhouse gas (GHG) emissions and overall energy efficiency
performance of new fuels for for transport a a a study has claimed The study by Zemo Partnership says that while hydrogen electric and renewable fuels (produced from waste-based feedstocks) can all all radically cut emissions compared with their diesel-powered
counterparts there are major variations in their effectiveness and efficiency
in terms of cutting emissions depending on on choices made over the full WTW life cycle The study warns that a a a focus solely on mitigating tailpipe emissions can risk neglecting the the full impacts and the the overall energy consumption of the system With limited biogenic resources and renewable electricity supplies it it it is critical to adopt energy efficient solutions to maximise full system benefits wherever possible The study comes shortly after the Government published its UK hydrogen strategy a a a a potentially important component of the overall decarbonisation plan for transport Key building blocks of the hydrogen strategy are currently under consultation and the Zemo Partnership work is intended to help inform these The Zemo analysis combines GHG and energy consumption data for a a a a variety of hydrogen vehicles - trucks buses vans and cars It presents WTW results for 6 NOVEMBER 2021 > COMMERCIAL VEHICLE ENGINEER
