The Big Chill: Highview’s Solution To The Challenge Of Long-Duration Energy Storage

In early June, Highview Power announced that it had officially launched its first grid-scale liquid air energy storage (LAES) plant at the Viridor Pilsworth site in Bury, United Kingdom (just outside of Manchester). This five megawatt (MW)/15 megawatt hour (MWh) facility is on the small side to truly earn the title of grid-scale, but that may be beside the point. The critical issue to consider here is that this new technology may ultimately prove to be a cost-effective long-duration energy storage resource that is – unlike compressed air energy or pumped hydro – geographically independent.

Further Tax Cuts on Li-ion Would be ‘Essential Boost’ for India’s Energy Storage Industry

India’s Goods and Services Tax (GST), a single tax applicable across the whole of the country, will be lowered for lithium-ion batteries by 10% in a move which has been welcomed by the India Energy Storage Alliance (IESA). All goods and services are taxable under the law, which was introduced in 2017. Along with a wide range of other changes, the GST rates on lithium-ion batteries has dropped from 28% to just 18%. In related news, fuel cell vehicles will see their GST reduced from 28% to 12%.

Sunnova Returns to the Arizona Solar Market, This Time With Batteries

Residential solar provider Sunnova is returning to Arizona after a period of regulatory tumult, and this time, it’s bringing batteries. The privately held company fast-tracked its SunSafe solar-plus-storage offering in the aftermath of Hurricane Maria, which left thousands of Sunnova customers in Puerto Rico without power even if their solar panels survived undamaged. Since then, the company has expanded its hybrid product to California, Massachusetts and now Arizona. That puts Sunnova into competition with Sunrun’s growing BrightBox product, and whatever is left of the company that used to be SolarCity.

Utility Rates Driving Record Demand for Home Energy Storage Systems

Installations of home energy storage system in the U.S. hit a record high in the first quarter of 2018, according to a new industry report. The new capacity of 36 megawatt-hours will sustain an estimated 4,000 home systems and adds to the 1,080 megawatt-hours installed in the past 4 years. The big picture: Home energy storage systems commonly use batteries to store the electricity generated by rooftop solar panels, which can then be used during peak times and on demand to reduce utility costs or for backup power during inclement weather. The increasing penetration of residential and commercial solar installations has lowered energy demands on utilities. But the policies they have implemented to offset those losses have ended up making home energy systems even more attractive.

The $3 Billion Plan to Turn Hoover Dam Into a Giant Battery

Hoover Dam helped transform the American West, harnessing the force of the Colorado River — along with millions of cubic feet of concrete and tens of millions of pounds of steel — to power millions of homes and businesses. It was one of the great engineering feats of the 20th century.
