Energy Storage

U.K. researchers have developed a battery with a photocathode made of vanadium dioxide, which is used to harvest light and store zinc ions and zinc oxide as a charge transport layer. The device showed an efficiency of around 1.2% and capacity retention of around 73% after 500 cycles.

U.S. researchers have concluded that wind and solar generation resources that were sized at 1.5 times along with three hours of energy storage would meet all but 200 hours of demand scattered throughout any given year.

An increasing share of residential solar arrays now include energy storage batteries. In part one of this two-part series, pv magazine reviewed the backup power features of batteries. In this part, costs, benefits and timing are evaluated.

H2X, a hydrogen vehicle manufacturer, has announced a deal with Gippsland Circular Economy Precinct in Australia to make a range of hydrogen-focused products. The move comes less than a week after Pure Hydrogen bought a significant stake in H2X Global.

Reports calculated that the single order would be enough to support production of 800,000 vehicles.

The Indian authorities have opened global bids to set up advanced-chemistry battery cell manufacturing units in India under the production-linked incentive scheme. Applications are open until Dec. 31, but bidders must commit to setting up a minimum of 5 GWh of capacity to qualify for the government subsidy.

In a chat with pv magazine at the Key Energy event in Rimini, Roberta Valenziani, of Italian trade body Elettricità Futura, explained the factors preventing Italy’s PV market from having a renaissance. She said the country has Europe’s longest delays and highest costs for obtaining permits for large scale solar.

Israel-based Augwind has built its first 250 kW/1 MWh compressed air storage system for the collective community of Yahel, in the southern, desert part of the country. The commercial scale facility will be connected to a PV system and will be used for behind-the-meter services.

From pv magazine Australia Lumea, the commercial arm of AustralianMega transmission network operator TransGrid, said commissioning of the $61.9 million Wallgrove Grid Battery has begun after it achieved registration with the Australian Energy Market Operator (AEMO) earlier this week. The 50 MW/75 MWh lithium-ion battery has been installed adjacent to Transgrid’s Wallgrove substation in Western […]

From pv magazine USA The gravity-based energy storage tower developed by Energy Vault has reached commercialization, with the company signing an agreement with DG Fuels to supply 1.6 GWh of energy storage. The tower will be charged with solar photovoltaic energy. The dispatched storage will support the creation of renewable hydrogen, biogenic based, synthetic aviation […]
