Distributed Storage

Lithium-ion batteries are a fantastic crutch for the renewable energy transition. It’s not all roses, though: Short duration limits, and potentially dangerous thermal runaway in rare circumstances, means the hunt continues for alternative electrochemical batteries. However, alternatives will largely complement lithium-ion batteries, rather than supersede them. Blake Matich looks at promising options to keep an eye on.

Australian energy storage company Redback Technologies has unveiled an expanded product range, adding a series of grid-tied solar inverters and new beefed-up battery products to its existing line of modular battery energy storage systems for residential and commercial customers.

Patriot Hydrogen has become the latest company to partner with the fast growing Singapore-based hydrogen-via-gasification outfit, CAC-H2.

A U.S. research team has sought to improve the way aluminium hydride is used for hydrogen storage. The material was nanoconfined in a framework that is claimed to be able to overcome the challenge represented by the thermodynamic limitation of hydrides in storing the clean fuel.

Reports calculated that the single order would be enough to support production of 800,000 vehicles.

Israel-based Augwind has built its first 250 kW/1 MWh compressed air storage system for the collective community of Yahel, in the southern, desert part of the country. The commercial scale facility will be connected to a PV system and will be used for behind-the-meter services.

A number of Australian battery material recovery projects got off the ground this week, including the completion of Western Australian outfit Neometal’s battery recycling demonstration plant, a Queensland-Japanese joint venture studying the extraction of cobalt from copper tailings as well as the funding of Sydney-based startup Novalith.

Factories suffering from rationed grid electricity could help drive a boom in on-site solar systems, and recent moves to mandate the retrofitting of PV on existing buildings could also lift the market, as analyst Frank Haugwitz explains.

Over recent years, the energy industry has been working hard to provide the structure and a regulatory framework for a market that recognises the value of coordinated demand response. Today marked the second wave — after the opening of the FCAS market in 2017 — of opportunity for organisations to trade their flexible electricity loads on the wholesale electricity market. The resulting efficiency gains are an important piece of the energy transition puzzle.

Construction has begun on a manufacturing pilot project to see battery-grade nickel, cobalt and manganese for precursor battery cathode materials (PCAM) in Perth. The facility is expected to be completed in early 2022 and is one of a number of developments that will look to establish Western Australia (WA) as a materials supplier to the growing battery manufacturing industry.
