mtu Hybrid PowerPack from Rolls-Royce enters passenger rail service

Green Car Congress

Together with the leasing company Porterbrook and Chiltern Railways, Rolls-Royce has converted a Class 168 DMU into the HybridFLEX train. Recuperated braking energy is stored in a battery, the mtu EnergyPacks. In pure electric operations, drive noise is reduced by about 75% (20 dB(A)).

Researchers at Korea University develop high-performance textile-based electrodes for watersplitting

Green Car Congress

An electrochemical water-splitting reaction offers an effective pathway to generate hydrogen fuels and store electricity from various intermittent but renewable energy sources. The team first converted silk textiles to carboxylic acid-functionalized conductive textiles using carbonization and a subsequent acid treatment.

Rolls-Royce developing methanol-fueled mtu engines for shipping

Green Car Congress

The energy density of methanol is high compared to other sustainable fuels and, thanks to its liquid state, it can be easily stored and refueled at ambient temperatures. Existing infrastructure can continue to be used in many cases. Unlike ammonia, methanol is not highly toxic and is environmentally safe.

nanoFLOWCELL to present new QUANT F flow cell EV at Geneva

Green Car Congress

The fact that we store the energy for our drive in a fluid provides us with enormous advantages over systems employed to date in the field of electric mobility. In turn, this buffer system is briefly able to supply over 2000 amperes when needed for full performance. Side view of the new QUANT F. Click to enlarge. This is unique.

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

It occurred in the wake of the California electricity crisis of 2000 and 2001, when mismanaged deregulation, market manipulation, and environmental catastrophe combined to unhinge the power grid. Electricity is a commodity that is bought and sold, and yet unlike most other commodities, it cannot easily be stored.
