Batteries

The U.S. battery specialist has signed framework agreements with four developers to deliver systems for multiple projects.

The project is relying on Sineng’s 3.15MW turnkey battery stations EH-3150-HA-UD 35 and is the first phase of a 300MW/600MWh that the Chinese state-owned power company China Three Gorges Corporation is building in China’s Shandong province.

The retirement of coal baseload capacity, some regulatory adjustments and high energy prices volatility could bode well for the deployment of batteries in Italy, and especially in Sicily. Problems, mostly related to the timing and the structure of the auction, remain, however. We spoke about it with Michele Scolaro, Aurora Energy Research Associate.

Scientists in the United States developed a lithium-sulfur battery using a commercially available carbonate electrolyte, that retained more than 80% of its initial capacity after 4000 cycles. The group used a vapor deposition process which unexpectedly produced a form of sulfur that did not react with the electrolyte, overcoming one of the key challenges for this battery chemistry.

The remote Australian township of Jabiru, deep in the heart of Kakadu National Park, has been powered 100% by solar PV during the final commissioning of the new Jabiru Hybrid Renewable Power Station.

Soluna’s new generator can be combined in a two-unit system to reach a capacity of 2.5kWh. It features built-in 120V(AC) output, continuous AC output power of 1,200W, and peak output of up to 2,400W.

In battery storage, there is no silver bullet chemistry type and as we move towards more ambitious decarbonization goals, room is being made for diverse systems. As an old technology with new vitality, zinc-based batteries are edging closer to commercialization, leveraging their unique ability to be configured for short and long duration operation. They are safer, longer lasting and, in some cases, reportedly up to 50% cheaper than lithium-ion batteries and, following recent game-changing advances, the prospects for zinc look much more exciting. pv magazine sat down with the manager of the newly established, global Zinc Battery Initiative, Josef Daniel-Ivad, to discuss the technology’s market position and developments.

Startup Rondo Energy closed a $22 million Series A funding round to decarbonize industrial processes with equipment that converts solar and wind energy into thermal energy.

Scientists in South Korea developed a porous carbon material that, when applied as a coating to the separator film in a lithium-sulfur battery, was shown to reduce an unwanted side effect and improve the battery’s performance and reliability. The coating is based on methylene blue, a type of salt commonly used in textile dying.

The Spanish energy company is building a huge hydropower complex across three water reservoirs in northern Portugal. The project will rely on 880 MW of pumped-hydro storage and is expected to become fully operational in 2024.
