DDFlyTrain flywheel hybrid technology to deliver around 10% fuel savings, rapid ROI
June 17, 2015
The DDFlyTrain research project, conducted by Ricardo, Artemis Intelligent Power (a group company of Mitsubishi Heavy) and Bombardier Transportation, (earlier post) has projects a fuel savings of around 10% based on the use of high speed flywheel brake recovery technology retrofitted to Diesel Multiple Unit (DMU) rolling stock. This order of saving means that the technology has a potential return on investment (ROI) of inside five years.
The DDFlyTrain hybrid solution—designed for integration onto a Bombardier Turbostar DMU—is based on Ricardo’s TorqStor high-speed flywheel energy storage technology and the high efficiency Artemis Digital Displacement hydraulic pump-motor transmission. (Earlier post.) The project has also produced a proof of concept test rig used to demonstrate the technology to rail industry stakeholders and a concept for integration onto a Bombardier Turbostar DMU.
Hydrogenics and Alstom Transport to develop and commercialize H2 fuel-cell commuter trains in Europe; €50M, 10-year agreement
May 27, 2015
Hydrogenics Corporation, a leading developer and manufacturer of hydrogen generation and hydrogen-based power modules, signed a 10-year exclusive agreement to supply Alstom Transport with hydrogen fuel cell systems for Regional Commuter Trains in Europe. Alstom Transport is a unit of Alstom, a France-based global leader in power generation, transmission and rail infrastructure with sales of €6.2 billion.
The agreement, valued at more than €50 million, includes the supply of at least 200 engine systems along with service and maintenance as necessary over a 10-year period. The fuel cell systems, based on Hydrogenics’s Heavy-Duty HD series fuel cells, will be developed to meet European train compliance regulations. The first units are expected to be delivered in 2016 following prototype work slated for late 2015.
Voith introducing new energy absorbers for trains made of fiber composite plastics
July 22, 2014
|Voith GFRP energy absorber: 60% weight reduction compared with standard steel absorbers. Click to enlarge.|
Voith is introducing a lateral energy absorber made of glass fiber reinforced plastics (GFRP) and aluminum. Compared with standard steel absorbers a weight reduction of 60% could be achieved. This new lightweight energy absorber is part of the mutable vehicle head concept Galea, but it can just as well be integrated into other front end systems.
The crash energy systems focus on vehicle safety and efficiency, as well as ecological benefits through a reduction of CO2 emissions. Their modular design allows short replacement times and an individual vehicle design.
