RSSB demonstrators to seek fuel-saving self-powering train alternatives
Two feasibility studies into alternative ways of powering trains and saving fuel will go ahead as demonstrators as part of the RSSB’s Powertrain programme, which seeks to develop innovative and sustainable technology for rail vehicles to power themselves.
The programme saw a total of 28 entries, eight of which successfully delivered RSSB-funded feasibility studies – including examples of cutting-edge power generation, energy storage, and several transmission technologies. Class 156 vehicles were used as references for all the proposals.
Of these eight, two will be funded as demonstrators to look at low-cost flywheels and digital displacement hydraulic machines, while a third group is searching for suitable test vehicles.
Lead project manager at the RSSB, Mark Benton, said: “These feasibility studies show that there is potential for the industry to reduce both emissions and fuel costs. Each of them has the potential to challenge the electrification programme business case and offer an alternative self-powered option.
“They work towards the RSSB’s vision, described in the Rail Technical Strategy, of a greener, cheaper railway of the future.”
The different studies offer alternative ways of potentially saving up to 30% in fuel efficiency, with similar reductions in carbon dioxide and nitrous oxide emissions. Successful methods in the programme could also suggest new approaches to the electrification of the network, particularly at high-cost locations near the periphery, the RSSB said.
The projects within the programme include:
- Fuel Cell Electric Multiple Unit (FCEMU)
- Digital Displacement Hybrid Rail Transmission
- High Efficiency Diesel-Electric Hybrid Rail Vehicle Power Pack
- Dual Fuel Technology for improving operating costs and emissions from DMUs
- Hybrid Electric Multiple Unit
- Low Cost Flywheel for Efficient Railways (LoCoFlyer)
- Reversible-Fuelcell Energy Tender
- Adapting Waste Heat Recovery Technologies for Diesel Multiple Unit Vehicles
