A comprehensive and policy-oriented model of the hydrogen vehicle fleet composition, applied to the UK market

Abstract Road vehicles play an important role in the UK’s energy systems and are a critical component reducing reliance on fossil fuels mitigating emissions. A dynamic model of light-duty vehicle fleet, based predator-prey concepts, is presented. This designed to be comprehensive but captures features competition between types car market. It allows predict evolution hydrogen vehicle’s fleet. The forecast effects policies, hence inform policy makers. In particular, it shown that transition happens only if supply can absorb at least 350,000 new per year. addition this, used demand for passenger fleet various scenarios. key finding policy-oriented successful clean before 2050 unlikely without policies fully support chain development. also shows amount required full currently not economically viable; needed infrastructure requires yearly investment larger than £2.5 billions. order mitigate these costs, focus should shift from hybrid range extenders transport system.
