Renewable Energy With General Motors Hybrid Cars
Continued from~GM Hybrid Cars
GM is showing that it is indeed committed to developing fuel efficient transportation through diverse energy sources. At a car show in Shanghai, GM introduced the E-flex hydrogen fuel cell moving toward an electric drive – the E-Flex electric architecture. This is touted to be the most efficient hydrogen fuel cell system so far.
This development of the E-flex System rides on GM’s several generations of fuel cell technology development: one that uses a lithium-ion battery that will allow up to 300 miles of emission-free, gas-less electric driving. The E-flex will be the ultimate zero emission vehicle that will operate on an all-electric platform generated from hydrogen fuel cell and grid electricity. The system is capable of being plugged-in, and for each charging, an additional 20 miles is attained. No more trips to the gas station really.
The variant of the E-Flex fuel cell system is a propulsion system developed for the Chevrolet Volt to be the most efficient fuel cell system. As it is configured to run on electricity generated from a number of electrical sources, the propulsion systems can be packaged in various scenarios depending on the available energy source.
Hydrogen electricity can be generated from renewable energy sources such as wind, solar, geothermal and biofuel sources, or it can be generated from natural gas, coal, or even gasoline, according to GM Research and Development. Studies reveal that hydrogen fuel cell technology will offer vehicles overall efficiency and lower harmful gas emissions compared to gasoline engines.

GM is confident that the fuel cell system will be highly competitive because of its numerous advantages. It acknowledges, however, that cooperation between governments and energy suppliers must be sealed in cooperation with the automotive industry to ensure the market for the fuel cell and hydrogen fuel vehicles.
