Carrier, a US-based heating solutions provider, has introduced a new line of heat pumps from 4 to 14 kW with a coefficient of performance up to 4.90. The system uses propane as a coolant and can reportedly reach a supply water temperature of 75°C. January 13, 2025 Emiliano Bellini Carrier has launched a new range of air-to-water heat pumps for residential and commercial applications. “This monoblock offers an impressive price-performance ratio, has a compact footprint and low refrigerant charge, further minimizing its environmental impact,” the manufacturer said on its Linkedin account, noting that the new product is designed for installation…
Researchers in Switzerland investigated different setups to maximize energy yield per surface area for PV systems on flat roofs. Their work showed that using horizontal tracking and single-axis reflectors could deliver up to 5% better performance. January 13, 2025 Valerie Thompson A group of scientists led by the Zurich University of Applied Science (ZHAW) in Switzerland performed simulations and measurements with the aim of maximizing energy yield in east-west oriented PV arrays installed on flat roofs. One of the experimental setups involved horizontal single-axis tracking (HSAT) with PV panels arranged in an east-west orientation with an atypically high area utilization…
Urgent responsibility was the overriding theme of the 15th annual meeting of the International Renewable Energy Agency (IRENA), which convened in Abu Dhabi on January 12. January 13, 2025 Blathnaid O’Dea Keynote speakers at this year’s IRENA meeting in the United Arab Emirates (UAE) called for a fairer distribution of financial resources to help the global South overcome energy-related challenges causing widespread inequality. ‘Accelerating the transition to renewable energy – the way forward’ was the theme of this year’s IRENA meeting, which took place on January 12 in Abu Dhabi. The agency’s director general Francesco La Camera said it had…
More than 182 MW of the battery energy storage systems (BESS) highlighted in the Spanish Official Gazette (BOE) are earmarked for hybridization with existing solar and wind energy generation capacity. January 13, 2025 Jose Pedrosa By ESS news pv magazine España lists the most notable energy storage projects announced in the Spanish BOE in the fourth quarter of 2024. Prior administrative permit and construction have been approved for the 27.46 MW BESS battery storage module FV Revilla-Vallejera Hybrid and the electricity evacuation infrastructure, for hybridization with the existing 44.199 MW FV Revilla-Vallejera photovoltaic plant in Vallejera, in Burgos, promoted by…
The indicative development area covers 2,400 hectares of agricultural land north-west of Leadenham, Lincolnshire. Image: Leoda solar park. Green energy company Telis Energy UK has unveiled plans for its first large-scale solar development requiring a development consent order (DCO). Telis Energy UK is part of the Telis Energy Group, a European green energy development platform established in 2022 and targeting a development pipeline of 10 GW by 2030, delivered through four subsidiaries in France, the United Kingdom, Germany and Italy. The UK subsidiary’s solar power plant proposals, called Leoda Solar Farm, would deliver a generation capacity of 500MW to 600MW,…
A Chinese research group has developed a new radiant cooling technology for photovoltaic devices. It consists of a chamber made of ethylene-tetrafluoroethylene and polydimethylsiloxane that, when placed above the solar cells, can reportedly achieve an average cooling capacity of around 40 W/m2. January 13, 2025 Lior Kahana Researchers from China have developed a new radiant cooling technology for photovoltaic devices that can reportedly achieve a cooling power density of up to 40 W/m.2 and a photovoltaic power density of up to 103.33 W/m2. Radiative cooling occurs when an object’s surface absorbs less radiation from the atmosphere and emits more. This…
Total reserve revenue reached an all-time high after the new Quick Reserve service went live on December 3. Image: Gresham House. Market analysis platform Modo Energy says December 2024 saw the highest battery energy storage revenues in Britain since January 2023. Modo recorded its highest monthly increase in four years, with revenues rising 65% to £84,000/MW/year between November. Battery energy storage revenues more than doubled in December compared to January 2024, when revenues averaged £36,000/MW/year. Modo said the high revenues were mainly driven by high wholesale price differentials, which rose 32% in December, and record balancing mechanism (BM) levels, with…
Microvast says its new True all-solid-state battery (ASSB) eliminates liquid electrolytes to achieve voltages from 12 V to 21 V, with a bipolar stack design that breaks the connections between cells, modules and packages. January 13, 2025 Emiliano Bellini By ESS news Microvast Holdings, a Texas-based battery manufacturer, said it has developed an all-solid-state battery that overcomes a key barrier to wider adoption: maintaining stable high-voltage operation without sacrificing long-term safety or reliability. “Traditional lithium-ion and semi-solid state batteries, limited by the limitations of liquid electrolytes, typically operate at nominal voltages of 3.2 V to 3.7 V per cell,” the…
Light flexible and radiation resistant organic solar cells for space Radiation tests suggest that carbon-based organic solar cells could surpass traditional silicon and gallium arsenide cells in efficiency and durability for space applications, according to a University of Michigan study. Previous research mainly investigated how radiation affected the energy conversion efficiency of organic solar cells. This new study delved into changes at the molecular level that worsen performance. “Silicon semiconductors are not stable in space due to proton radiation from the sun,” explains Yongxi Li, first author of the study and former UM researcher in electrical and computer engineering. “We…
Conventional silicon solar cells degrade quickly in space, and gallium arsenide cells are heavy and inflexible. Research from the University of Michigan shows that carbon-based solar cells could be well suited for space applications. January 13, 2025 Ryan Kennedy By pv magazine USA A University of Michigan study has found that carbon-based solar cells, also called organic solar cells, may outperform conventional silicon solar cells and gallium arsenide solar cells in space applications. Silicon solar cells used on Earth deteriorate quickly when exposed to the harsh radiation of space. Alternatively, gallium arsenide solar cells are used today on satellites and…
