PV-powered thermoelectric cooling for air conditioning in buildings
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.
New polymer-based battery electrodes with high stability
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.
Indonesia may add 66 GW of solar by 2030, says IRENA
The International Renewable Energy Agency (IRENA) says that solar could become the backbone of Indonesia’s energy system by 2030. However, the nation’s own expectations are still far off from IRENA’s scenarios.
India’s SECI launches 1.2 GW hybrid wind-solar tender
Solar Energy Corp. of India (SECI) said developers have until Dec. 12 to submit bids for 1.2 GW of wind-solar-storage hybrid capacity. The projects will be developed on a build-own-operate basis, anywhere in India.
Australian miner signs baseload PPA contract with Neoen for 24/7 renewables
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.
US utility-scale solar slowed in Q3
US solar had its worst quarter in two years in terms of deployment, due to global supply challenges that slowed growth, delayed projects, and drove up prices.
Equinor acquires Danish solar developer
Equinor is set to fully acquire developer BeGreen, which has a project pipeline of more than 6 GW in Denmark, Sweden and Poland.
Air-source heat pump for harsh, cold climates
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.
UK developer acquires Europe’s largest PV project
UK independent power producer Rezolv Energy has acquired the late-stage development rights to a 1,044 MW solar project in Arad county, Romania. The Eastern European country is preparing to roll out a contract-for-difference (CfD) scheme early next year to deploy 3.5 GW of solar and wind.
New standardized guidelines for solar O&M
IEA-PVPS has standardized guidelines for O&M programs for large-scale solar plants. It defines O&M performance indicators and standard O&M operator services, as well as tools to analyze PV plant performance and safety.
