Storage

Fire crews in Chandler, Arizona, sent robots into a building at the Salt River Project where a 10 MW battery was smoldering.

The town of Walpole on Western Australia’s southernmost tip will soon be powered by a pumped-hydro microgrid, a first for the state which is already renowned for its rollout of microgrids and distributed renewable solutions.

Developed by Dutch start-up AquaBattery, the storage technology is claimed to independently amend power and energy capacity. The battery system utilizes three storage tanks, one with fresh water, one with concentrated salt water and one with diluted salt water, and also relies on membrane stacks.

Chinese inverter maker Growatt has launched Infinity 1500, a portable power station for off-grid applications.

Two different studies have highlighted the potential and challenges of low-head pumped hydro storage (PHS), which has so far never been implemented in real projects. Different main areas were identified for future research and an interesting levelized cost of storage was indicated for certain project configurations.

The hydrogen generation facility will be initially powered by a photovoltaic plant, but Essent may also add wind power for periods when the sun is not shining. The energy company also plans to deploy some battery storage capacity at the plant for the temporary storage of the surplus of solar power that cannot be immediately converted into hydrogen or supplied back to the grid.

A new report from IEEFA says green ammonia could help India significantly reduce its trillion-rupee fertilizer subsidy bill and cut dependence on liquefied natural gas (LNG) imports for fertilizer production.

Developed by Canadian start-up Salient Energy, the zinc-ion battery has a rated capacity of 60 Ah, a nominal voltage of 1.3 V, and a volumetric energy density of 100 Wh/L. The device measures 26cmx24cmx1.2cm and weighs in at 1.3 kg

pv magazine publisher, Eckhart Gouras, interviewed Diego Mesa, the Colombian Minister of Mines and Energy at the BNEF Summit in New York. Mesa recounted the history of solar PV adoption in his country and provided details on the most recent developments, including the construction of Colombia’s largest solar park by Italian group Enel and the first large scale battery project by Canadian Solar.

Salzgitter has claimed a record efficiency level for its EU-funded GrInHy2.0 hydrogen project, which is based on solid oxide electrolysis cell tech. The high-temperature electrolyzer uses waste heat from the company’s steel production processes.
