A prototype, twin-turbo, Aston Martin Rapide S at the 41st ADAC Zurich 24 Hours of Nürburgring (19-20 May 2013) will debut Alset Global’s dual fuel Hybrid Hydrogen system, which enables the turbocharged 6.0-liter V12 engine car to run on pure gasoline or hydrogen or a blend of both.
Austria-based Alset Global’s Hybrid Hydrogen system comprises a hydrogen fuel rail, storage tank and proprietary engine management system. The system can use either pure hydrogen, gasoline or a blend of both to deliver optimum power, acceleration and CO2 reduction.
Four carbon-fiber tanks holding 3.23 kg of gaseous hydrogen—two housed next to the driver and two in the trunk of the car—and the refueling system developed by Alset Global and its partners are approved by German motorsport’s governing body, the DMSB. In addition, the use of the existing 6.0 liter engine will showcase that engine downsizing or electrification is not the only way to achieve low emissions, the company said.
Alset Global and its partner organizations hold a number of key patents relating to the entire system. Integral to Alset’s core technology is a proprietary system especially designed and programmed to adjust and control all of the engine’s functioning variables in order for the engine to burn hydrogen during combustion, while maintaining the same engine performance as when burning gasoline. This proprietary system is programmed into the vehicles’ ECU as a second engine management mode (Hydrogen mode).
A special control system allows instant shifting from one engine management software to the other. The engine’s variables are instantly adjusted and controlled as the engine switches back and forth from hydrogen to gasoline. The shifting process occurs seamlessly while the engine is running, even at high speeds.
Partners include Magna Steyr, which has developed the storage tank and pressure regulation system; Linde, which will supply the hydrogen for the race; Gigatronik, which has supported the programming software verification and loop testing; and TÜV SÜD, which certified the technical safety requirements for the hydrogen system.
Our system offers, dependent on tank size, a range of up to 250 km [155 miles] with zero [tailpipe] CO2 emissions.— Alset Global’s VP of product management and technology, Thomas Korn.
(Previously at BMW, Korn has an extensive background working with alternative propulsion technologies such as hydrogen internal combustion engines, fuel cells and electric drive trains as well as the certification and homologation processes.)
Alset estimates that applying its dual fuel Hybrid Hydrogen system would entail a price premium of around 15 % over today’s new car prices.
