Energy Storage

Simpliphi, a US-based storage system provider, said its new storage system includes a 4.9 kWh battery and a 6 kW inverter. The solution can be scaled up to 358.8 kWh of storage capacity.

Scientists have proposed a way to combine thermoelectric modules (TEMs) with rooftop PV to support heating, ventilation and air conditioning in buildings. They designed a wall-integrated TEM to heat and cool adjacent rooms.

UK researchers have developed organic electrode materials to integrate redox-active organic molecules into long-chain polymers. The new electrodes exhibit better cycling performance in lithium-ion batteries, with no apparent capacity decay over more than a thousand charge-discharge cycles.

Carrier will soon begin field tests for a prototype air-source heat pump for cold climates. It is designed to provide high-efficiency heating performance in harsh climates with temperatures equal or below negative 29 degrees Celsius, while being grid-interactive. The US-based heating tech specialist expects to commercialize the solution by 2024.

While still using conventional lithium-ion raw materials, 24M’s technology is said to reduce the number of steps required to manufacture battery cells and thereby the cost by up to 40%. The US company’s SemiSolid design is also said to deliver improved energy density, safety and recyclability.

Su-vastika introduced a three-phase uninterruptible power supply (UPS) system with power ratings of 10 kVA to 500 kVA. The backup time provided by the system can be extended by using solar power in conjunction with the battery bank.

Australian startup Vulcan Energy announced it produced high grade lithium hydroxide which ‘easily exceeds’ battery grade specification.

The worst effects of the pandemic may have passed but supply chain disruptions continue to be felt across the world. The effects of the war in Ukraine are also evident to all of us in our daily lives, from commodities to energy, food supply chains and beyond. The disruption in the battery energy storage system (BESS) supply chain is no different, writes Cormac O’Laoire, senior manager of market intelligence at Clean Energy Associates. Indeed, as the cost of raw materials such as lithium climbs, battery prices are being driven materially higher, on some accounts by 20% to 30%, rendering some projects uneconomical.

US startup Quino Energy has raised more than $7.8 million to scale up its quinone redox flow battery technology. Harvard University and University of Cambridge researchers came up with the initial research for the battery design.

Axium Infrastructure and Canadian Solar have developed a 350 MW/1400 MWh energy storage system in California.
