The Chinese Academy of Sciences has switched on a 100 MW compressed air energy storage system in China’s Hebei province. The facility can store more than 132 million kWh of electricity per year.

Enel Green Power’s new solar panel has average efficiencies ranging from 22.6% to 22.9% and a temperature coefficient of -0.24% per degree Celsius. It is based on an n-type solar cell with G12 format and a power conversion efficiency of 24.6%.

Developed by the French research institute Liten, the prototype kit consists of a 145 W PV panel, a magnetic rear panel, and an MPPT charge controller. It also includes a battery and a micro-inverter that can be used to inject the stored energy into the grid when the vehicle is recharged.

United Renewable Energy has energised a 15 MW/15 MWh battery energy storage system connected to a 150 MW solar park located near the southern Taiwanese city of Tainan.

The two batteries have a storage capacity of 13 and 19.5 kWh, respectively. Both lithium-ion systems use LiFePO4 as the cathode material and have a round-trip efficiency of over 86%.

Energy Vault’s EVx storage system is comparable to pumped hydro, using grid-scale renewable energy when supply is abundant to drive motors and raise 30-ton blocks on a six-arm crane tower, rather than water, up to a height. When power needs to be discharged back to the grid, the blocks are lowered, harvesting the kinetic energy.

United Kingdom-based SolarBotanic Trees will begin offering its solar trees in early 2023. The systems will use monocrystalline cells with an efficiency of up to 24%, encapsulated in a 3D shape.

A team of scientists in the United States have designed a transparent organic photovoltaic material for solar window applications in commercial buildings.

A 3 GW solar installation will be built in the Tengger Desert, in northern China. It will require an investment of around $3.18 billion (CNY 15.25 billion).

A team of Australian scientists have developed a new way to produce hydrogen using water from the atmosphere. They claim their new module can ensure stable performance and provide green hydrogen for remote areas.
