General Motors aims to commercialize battery, fuel cell technologies, be automaker of the future

In its storied past, General Motors Co. built refrigerators, locomotive engines and a gamut of auto parts before dumping those businesses in a long-running battle to return to profitability.

The 112-year-old automaker is making money again and back in the business of building product for others, this time developing green powertrains for the future while the nation reckons with rising climate change concerns and a coming wave of electric vehicles.
