The Guardian reports: The forerunners of ExxonMobil patented technologies for electric cars and low emissions vehicles as early as 1963 – even as the oil industry lobby tried to squash government funding for such research, according to a trove of newly discovered records.

Patent records reveal oil companies actively pursued research into technologies to cut carbon dioxide emissions that cause climate change from the 1960s – including early versions of the batteries now deployed to power electric cars such as the Tesla.

Scientists for the companies patented technologies to strip carbon dioxide out of exhaust pipes, and improve engine efficiency, as well as fuel cells. They also conducted research into countering the rise in carbon dioxide emissions – including manipulating the weather.

Esso, one of the precursors of ExxonMobil, obtained at least three fuel cell patents in the 1960s and another for a low-polluting vehicle in 1970, according to the records. Other oil companies such as Phillips and Shell also patented technologies for more efficient uses of fuel.

However, the American Petroleum Institute, the main oil lobby, opposed government funding of research into electric cars and low emissions vehicles, telling Congress in 1967: “We take exception to the basic assumption that clean air can be achieved only by finding an alternative to the internal combustion engine.” [Continue reading…]
