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.

Servotech Power Systems, with the support of German development agency GIZ, has installed 10 portable solar rooftop systems at the Swaminarayan Akshardham temple complex in the Gandhinagar district of Gujarat.

Building-integrated photovoltaics provider Mitrex said its system will provide St. Mary’s University student residence with a power-producing microgrid.

Reversible fuel cell systems based on solid oxide cell (SOC) technology may become an efficient tool to cope with price volatility in the energy market, according to new research from Stanford. Through the proposed model, which mainly considered the electricity markets in Germany and Texas, the research group found that the reversible system may be competitive at current hydrogen prices, provided that there is sufficient variation in daily electricity prices.

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.

Land-scarce South Korea is currently hosting a series of initiatives aimed at deploying solar on unused surfaces. The latest development comes from the city of Suncheon, which will test several photovoltaic railroad noise barriers based on bifacial PV modules.

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

The results from solar glass company ClearVue’s greenhouse trials at Murdoch University have found the company’s product performed better than predicted overall, demonstrating both strong power generation and thermal value.

Created by a Dutch group of companies and research institutions, the mobile solar system may also be combined with an electrolyzer for hydrogen generation. Two prototypes are currently being tested by a farmer and a research institute in the Netherlands.
