Short payback periods for PV-powered heat pumps in Spain
Spain’s National Confederation of Installers has released a technical paper about the advantages of coupling rooftop PV with heat pumps. It says that the payback time for a solar-powered heat pump can range between two and five years.
Iberdrola moves forward with Portugal’s largest pumped-hydro storage project
The Spanish energy company is building a huge hydropower complex across three water reservoirs in northern Portugal. The project will rely on 880 MW of pumped-hydro storage and is expected to become fully operational in 2024.
Storing solar power with grid-scale molten hydroxide
Seaborg Technologies, a Danish manufacturer of molten salt nuclear reactors, has turned a technology that was originally developed for nuclear power into a large-scale storage solution for wind and solar. It has developed a storage system that uses renewable energy to heat salt with electrical heaters, based on two-tank molten salt storage designs developed for concentrated solar power plants.
Grazing animals increase carbon sequestration by up to 80% in PV projects
Temple University researchers have found that managed sheep grazing on an acre of recovering agricultural soil with native plants may sequester 1 ton of carbon per year, which could accumulate for 12 to 15 years before reaching saturation.
Australia’s battery capacity to double in 2022
After the deluge of announcements last year, 2022 will see the trickle of big batteries actually operating in Australia turn to a flood. According to Rystad Energy, the country’s battery capacity is set to double before the year is out.
Robot dog for PV plant monitoring
Spanish renewable energy company Acciona is using a robot dog, instead of drones, to monitor a solar park in northern Chile. The device has a built-in thermal vision system that generates thermographic reports on the status of the different PV plant components, as it walks between the panel rows following a programmed route.
Taiwan sets solar FITs for 2022
The new feed-in tariffs range from NT4.0031 ($0.14) to NT5.8952 ($0.21) per kWh. PV systems of all types will be applied a grid tariff of NT0.0656 ($0.002)/kWh and the funds raised through this fee will be used to set up a PV module recycling scheme.
Italian region devotes €22 million to ‘energy communities’
Italy’s Lombardy region will use €22 million to build up to 6,000 “energy communities,” for a total installed capacity of up to 1.3GW.
Net metering would offer a solar rooftop alternative to uneconomic Kenyan utilities
Commercial and industrial clients across the continent are turning to solar amid fears ever more cash-strapped conventional electricity companies will be unable to invest in their creaking grids, an online event has heard.
Large-scale storage options for compressed hydrogen
Researchers from Finland and Sweden have reviewed different ways to store compressed gaseous hydrogen, including storage vessels, geological storage, and other underground options.
