    UK Study Says Yes To Solar-Powered Electric Trains

    Imperial research finds electric railways could be powered by subsidy-free solar

    Neasan O’Neill, 6 December 2017 (Imperial College, London)

    “…[S]olar panels connected directly to railways in the UK could meet a significant amount of their electricity demand…[A substation system would use custom power electronics and bypass the electricity grid altogether…[Riding Sunbeams] found that solar arrays and integrated energy storage devices could supply around 10% of the energy needed to power trains on the UK’s DC electrified routes each year. Crucially, the research found that this clean, renewable power could be supplied at a lower cost than electricity supplied via the grid today…The biggest opportunity identified in the study is on the commuter rail network south of London. If 200 small solar farms were installed alongside railway lines they could provide 15% of the power needed to run trains on these routes…[A] similar system could provide 6% of the energy used on the London Underground and 20% of the electricity used by the Merseyrail network in Liverpool. The news was even better for electric railways closer to the equator, these could run entirely on solar power without having to rely on the local electricity grid…” click here for more
