AHL-TECH's ethanol-powered train profiled
In Michigan, AHL TECH is developing an ethanol-powered/hybrid electric train engine in what it hopes will eventually replace the current fleet of diesel-powered trains. Much like diesel-electric locomotives, an ethanol-fueled engine powers a generator connected to the locomotive’s axles. However, unlike the diesel-electrics, AHL-TECH’s ethanol-hybrid also has a battery component.
Instead of a direct correlation between the speed of the engine and the power transmitted by the generator, AHL-TECH’s design features the capacity to store electricity when the generator produces more power than is being used. This gives the locomotive the ability to power the axles by running the engine or using power stored in the main battery. It also allows for regenerative braking – capturing the energy lost when a locomotive is brought to a halt.
