Distributed Storage

Scientists at Monash University claim to have developed the world’s most efficient lithium-sulfur battery. They say the new device could enable an electric vehicle to drive more than 1,000km on a single charge.

A joint venture with Japanese peers Toshiba and Denso will make the investment in the Gujarat plant over the 2021-25 period, having pumped $174 million into the first phase of development.

The Japanese electronics giant is offering a new cell architecture developed by battery start-up 24M, in the U.S., which significantly improves battery economics. Kyocera will be the first company to bring the technology to market.

Sun Da has moved to become the lithium energy storage and electric vehicle battery company’s second largest investor, raising HK$10.3 million for the business in the process.

To get long-duration storage costs down to $0.05/kWh, research teams funded by ARPA-E are pursuing breakthroughs in flow batteries, hydrogen storage and other technologies – even thermovoltaics.

Storage has long been expected to be the handmaiden of a renewable energy world and its long awaited advances started to finally emerge in the third quarter as researchers posited R&D achievements ranging from potentially potent tungsten disulfide nanotubes to the business case for 10-year solar panels.

Intersolar Europe is always a key date in the solar calendar but this year’s show had it all, including three panel-smuggling arrests. Elsewhere, wafers were getting bigger, efficiency records were tumbling and new technologies were emerging. There was also more news on the solar car ports fad and Hanwha’s ongoing legal tussle.

With demand for lithium-ion battery cells picking up, largely driven by EVs but also from the fast-growing stationary storage segment, production capacities in China are ramping up quickly. But safety and quality must remain centrally important in the face of the need to scale, even more so after the numerous battery fires that shocked buyers globally and brought the South Korean market to a standstill. Clean Energy Associates (CEA) has launched the 2019 BESS Supplier Market Intelligence Program report, covering 40 suppliers, in an effort to support buyers navigating this novel supplier landscape. George Touloupas, CEA’s director of technology and quality for solar and storage, shares the company’s key findings on the supply chain and tells us what can have an impact on Li-ion safety and reliability.

Evergen, a solar and battery optimization specialist, and battery supplier Solar Service Group have joined forces to connect thousands of residential batteries across Australia. By delivering significant benefits to consumers, the joint venture hopes to boost the uptake of home batteries across the nation.
