Researchers from Egypt and Great Britain have developed a new floating PV system concept that uses compressed air for energy storage. The system has a round trip efficiency of 34.1% and an exergy efficiency of 41%. December 11, 2024 Emiliano Bellini Scientists from Port Said University in Egypt and the University of Strathclyde in the United Kingdom have proposed combining compressed air energy storage (CAES) with floating solar photovoltaics through a new energy management strategy. “To overcome the intermittency and availability problems of solar energy, the proposed floating PV system is equipped with an environmentally friendly hybrid compressed air energy…
Battery prices continue to fall due to lower metal costs and increased scale, putting pressure on margins for manufacturers. Further price declines are expected over the next ten years. December 11, 2024 Marija Maisch By ESS news Battery prices saw their biggest annual decline since 2017, with lithium-ion battery pack prices falling 20% from 2023 to a record low of $115/kWh, according to analysis from BloombergNEF (BNEF). Factors driving this decline include overcapacity in cell production, economies of scale, low metal and parts prices, the adoption of cheaper lithium iron phosphate (LFP) batteries and a slowdown in electric vehicle sales…

An international research group has developed a light upconversion system that can reportedly improve the efficiency of crystalline silicon solar cells by as much as 0.87%. The technology consists of multilayer nanoparticles that act as near-infrared absorbers over different spectral ranges. December 10, 2024 Lior Kahana An international research team has developed a multiband near-infrared (NIR) upconversion (UC) system to improve light output in silicon solar cells (SSCs). The system is based on the idea of lanthanide-doped upconversion nanoparticles (UCNPs), which convert low-energy photons in the infrared range into higher energy photons in visible light. “We have developed an efficient…
As the German battery energy storage sector booms, developers should be aware of the various hurdles they need to overcome and can learn lessons from the UK battery market. December 11, 2024 Baris Serifsoy, Thomas Dörmer, Tim Heitling Eco Stor is planning many large storage facilities in Germany Image: Eco Stor By ESS news Germany’s renewable energy industry is in full swing, delivering new generation capacity to the electricity grid at unprecedented levels. With an installed capacity of 90 GW by mid-2024, of which 7.5 GW newly installed in the first six months of 2024, the solar energy market is…
Netherlands-based Volta Energy has launched a 15 kVA portable solar generator to provide off-grid power equipment for use on construction sites. The system includes solar panels, an inverter, battery, trailer and a backup biodiesel generator. December 11, 2024 Valerie Thompson The Dutch Volta Energy has launched a 15 kVa hybrid solar generator with integrated biodiesel for construction sites and water pump installations. It is the latest in its line of rental systems that range in size from 6 kVA to 120 kVA. For example, the smallest is suitable for powering a security camera on a construction site, while larger units…

The American Legislative Exchange Council (ALEC), America’s largest membership organization of state legislators committed to the principles of free markets and federalism, unanimously adopted the “Resolution in Support of Agriculture and Energy Production” last week at the States & Nation Policy Summit in Washington. accepted. The resolution, introduced by Weld County Republican Commissioner Lori Saine, supports allowing community solar and agrivoltaic energy projects on farmland. The resolution will boost consumer choice and energy options that support family farms, while also increasing domestic energy production, such as community solar. “American farmers and ranchers deserve to have choices about how they produce…
