Super-fast, long-life aqueous rechargeable zinc battery
An international group of researchers has demonstrated an aqueous zinc battery with excellent performance in terms of capacity, rate capability, specific energy, and output voltage. The supercapacitor-battery hybrid device has also shown unprecedented cycling stability 99.2% capacity retention after 17,000 cycles at 100% depth of discharge.
IEA PVSP predicts high-cost, low-revenue scenario for solar recycling
A recent report by the International Energy Agency Photovoltaic Power Systems Programme (IEA PVSP) reviews the current regulatory and industrial landscape for end-of-life PV management in Germany, France, Italy, Spain, Japan, South Korea, China, Australia, and the United States.
Taiwan’s largest battery comes online
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.
IRENA highlights solar critical to ASEAN energy transition
Indonesia will have to get to work installing more than 24 GW of solar this year – and every year – if the region is to achieve the 2.1 TW to 2.4 TW of photovoltaics the International Renewable Energy Agency has estimated it will require to achieve a net zero carbon energy system by 2050.
Taiwanese battery maker targets NT for manufacturing plant
The Northern Territory government has signed an agreement with Taiwanese battery company Aleees and Western Australia-based miner Avenira to develop a battery cathode manufacturing plant in Darwin.
Ark Energy floats 3 GW renewables hub for Queensland
International metals group Korea Zinc’s Australian subsidiary Ark Energy has announced it will build 3 GW of renewable energy generation in north Queensland as part of plans to produce more than 1 million tonnes of green ammonia per annum for export by 2032.
Longi achieves 26.12% efficiency for gallium-doped p-type heterojunction solar cell
The result, confirmed by Germany’s Institute for Solar Energy Research Hamelin (ISFH), was achieved on a heterojunction solar cell based on an M6 wafer.
Energy Vault to deploy 2 GWh of gravity storage in China
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.
Pumped hydro storage takes shape in the Philippines
Prime Infra recently acquired a 500 MW pumped storage hydropower project in Rizal province in the Philippines. The company is also developing a 1.4 GW facility in the country.
Indian developer unveils plan to install 1.5 GW of hybrid wind-solar
Indian renewable energy developer Serentica Renewables plans to install and commission 1.5 GW of solar and wind capacity in 24 months to serve energy-intensive industries in the Asian nation.
