South Africa launches tender for floating, ground-mounted PV
The South African government is looking for independent power producers to build and operate floating or ground-mounted PV projects at selected government waterworks infrastructure or damns. The projects should be operational for 20 years.
Temperature estimates for floating PV modules
Scientists from the United States and Brazil have developed four different ways to estimate the temperature of floating PV modules. They validated the models with temperature measurements from a floating solar plant in Brazil.
Enel starts building 170 MW of agrivoltaics in Italy
Enel Green Power says it has started working on the largest agrivoltaics plant in Italy. It will feature bifacial PV modules mounted on trackers. Olive trees will grow around the solar panel rows.
FERC says 1,700 GW of US renewables still awaiting interconnection
The US Federal Energy Regulatory Commission (FERC) says that just 86 GW of power projects based on fossil fuels are awaiting interconnection, while 1,700 GW of solar, wind, storage remain delayed.
New propane heat pump for district heating
Swedish manufacturer Qvantum has developed a 6 kW heat pump for apartments connected to district heating systems. It uses propane (R290) as the refrigerant.
Novel oxygen-ion battery may offer longer lifespan, claims TU Wien
Austrian scientists have created a lab-scale, solid-state, oxygen ion battery based on mixed ionic electronic conducting (MIEC), which is a special class of non-flammable electroceramic materials. The battery has around 30% of the energy density of lithium-ion batteries but can purportedly achieve a longer lifespan.
New Zealand moves forward with 8.5 TWh pumped hydro project
The New Zealand government will investigate the viability of establishing a pumped hydroelectric facility on the South Island. The project could provide up to 8.5 TWh of annual generation and storage capacity to support the nation’s transition to 100% renewable electricity generation.
New tool to estimate efficiency, savings of ground-source heat pumps
Researchers from Oak Ridge National Laboratory have developed a free, web-based application that calculates the savings and energy efficiency of residential ground-source heat pumps compared to gas heating.
Cape Verde kicks off tender for 3.4 MW of solar
The government of Cape Verde is seeking developers to build four solar plants across four islands in the archipelagic nation.
New global solar capacity additions hit 191 GW in 2022, says IRENA
