New Technologies, Contracts Bolster Growing Energy Storage Business

Promising technological advances and a host of lucrative new contracts and incentives are encouraging signs to alternative energy watchers who say that the market for storing wind and solar-generated electricity could become a multibillion-dollar industry in the next decade.

Electric engineers have long argued that affordable and reliable energy storage is an essential component of an electric power grid that is supplied by an ever-growing share of renewable energy. That’s because the sun doesn’t always shine and the wind doesn’t always blow exactly when utilities need it to.

But the cost of energy storage, until recently, remained too high to serve as a practical option. Instead, utilities largely relied on so-called “peaker plants” that they can ramp up within a few minutes to meet demand when, for example, air conditioners are cranked up on a steamy summer day.

Who Digs Solar and Wind Power? That’s Right: Miners

Mines from the Americas to Africa and Australia are slowly becoming unlikely hotspots for the production and use of green energy.

In some places, wind and solar farms resurface revenue from deserted mine lands. Elsewhere, mining companies are powering a portion of ongoing operations with renewable energy, which is now cost competitive with traditional fossil fuels and gives a green sheen to an industry often maligned by environmentalists.

To be sure, these are early days for these strange bedfellows. The reason for the coupling of mines and green energy varies from site to site and country to country, according to experts, but the trend is global and growing.
