Energy Storage

Renewables developer Vast Solar has signed a key engineering contract as it pushes toward construction of a 30 MW/288 MWh thermal concentrated solar power (CSP) plant with more than eight hours of energy storage capacity near Port Augusta, South Australia.

Researchers in India have simulated a 4 kW solar power-based hybrid electric vehicle (EV) charging station using a three-stage charging strategy and found that the station is capable of charging 10–12 EVs with 48 V 30 Ah lithium-ion batteries.

Vale and Central South University have launched a joint laboratory for low-carbon and hydrogen metallurgy in Changsha, in China’s Hunan province, while Nippon Steel has secured approval to acquire U.S. Steel.

Dismissed by many in the solar industry as an overly-complex, outdated technology, concentrated solar power (CSP) is set for a comeback thanks to a scaled-down, modular approach.

Researchers in Japan have developed a novel cathode material for rechargeable magnesium batteries (RMBs) in the form of rocksalt oxide. This new material reportedly enables efficient charging and discharging even at low temperatures.

Battery research is advancing to address issues in the lithium-ion development process and concerns about safety and aging. Vehicle-to-everything (V2X) tech, meanwhile, is in the starting blocks, but interoperability is the key hurdle to achieving mass market penetration.

Researchers in China have developed a photovoltaic cold storage system that is reportedly able to improve refrigeration capacity and ice storage rate. The system is said to ensure a stable cooling system operation for the refrigeration needs of agricultural products.

The mini-grid, expected to connect over 1,500 residents to electricity, is part of the company’s wider plans to install over 20 mini-grids in Benin, which will serve more than 30,000 people across 20 rural localities collectively, through a total 1.2 MW capacity.

In this edition of the Weekend Read, we turn to Egypt. The gigawatt-scale Benban project showcases the North African country’s solar potential, and premium prices for gas exports make the case for a more diverse energy mix. A nation with grand renewables targets – but slow installation rates – may finally be weaning itself off fossil fuel resources.

Engie has told pv magazine that the developers of the H2Sines.Rdam installation have decided to terminate the project to produce hydrogen in Portugal and send it to the Netherlands, while Fortescue said it has opened an electrolyzer production facility in Australia.
