A new fywheel-based regen- erative braking system, the Digital Displacement hydraulic pump-motor transmission system from Artemis Intelligent Power (Loanhead, UK), has demonstrated that it can reduce the carbon footprint of trains. It stores and then reuses energy, by means of Ricardo's (Shoreham-by-Sea, West Sussex, UK) TorqStor high speed fywheels, which spin at 45,000 rpm. Artemia, Ricardo and rail technology frm Bombardier Transportation (Berlin, Germany) have formed the DDfyTrain consortium to demonstrate that this technology could work on diesel-driven commuter trains. In an article at theengineer.co.uk by Julia Pierce, David Rollafson, VP global innovation at Ricardo, points out, "Every train journey involves a lot of stopping and starting, and so also a lot of braking and acceleration. If we can harvest some of the energy from braking and use this when the vehicle is gathering speed again, we can save a lot of diesel and, so, a lot of money for train opera- tors." Pollution also would be reduced. "Pulling out of a station, diesel engines pump out a lot of pollution," he notes. "Adding stored energy to help accelera- tion would reduce this." The DDfyTrain system is reportedly easy to retroft and it's modular — operators could scale up energy storage as fnances permit. The consortium is now discussing applica- tion of its technology with a number of UK train operators. Ricardo's TorqStor technology combines a modular, high efciency, carbon fber composite fywheel with a magnetic coupling and gearing system that enables a scalable range of energy storage capacities for diferent equip- ment applications. Rollafson adds that the technology also could reduce costs and save fuel in commercial trucks and in mining and construction equipment: "We are actively seeking further opportunities to realize the benefts of TorqStor in new sectors."
