Energy Storage

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.

BHP has signed a 70 MW baseload renewable energy contract with Neoen to meet 50% of the energy demand of its Olympic Dam mining operations in South Australia.

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.

The Asian Development Bank (ADB) and Électricité du Cambodge (EDC) have signed an agreement to develop 2 GW of solar in the Southeast Asian country. EDC will conduct a nationwide study to identify potential solar and storage projects for implementation up to 2030.

Researchers in Singapore have developed a new light-triggered coupled oxygen evolution mechanism that builds on past oxygen evolution research. Oman, meanwhile, has announced a new hydrogen strategy.

An Israeli scientist has proposed a way to achieve uninterrupted PV power on the moon without using energy storage. The proposal involves the installation of PV panels around a 360-degree latitudinal ring close to one of the moon’s poles. There would be no inter-array shading, and static vertical PV arrays and arrays mounted on single-axis vertical trackers could be viable mounting structures.

US researchers have facilitated the decoupling of power from energy design by incorporating a conducting carbon slurry in the negative electrolyte of an all-iron flow battery. In a new study, they describe the design considerations for slurry iron redox flow battery scalability.

In an unexpected move, the government of Thailand has introduced a feed-in-tariff (FIT) of THB 2,1679 ($0.057)/kWh over 25 years for solar and a 25-year FIT of THB 2,8331/kWh for solar plus storage.

PG&E has secured approval to set up a vehicle-to-grid (V2G) export compensation mechanism for commercial EV charging customers in California. Sono Motors is debuting its Sion solar electric vehicles in the US market, while Toyota and Jera are installing innovative second-life battery systems in Japan.
