A tribal solar project. Terrace mart Alliance for Tribal Clean Energy, in partnership with the John D. and Catherine T. MacArthur Foundation, William and Flora Hewlett Foundation, The Lemelson Foundation and other philanthropies, launched the Indigenous Power & Light Fund for Energy Sovereignty at the Clinton Global Initiative Annual 2024 meeting, where the Fund will be presented by the Clinton Foundation as a commitment to action. Aimed at accelerating the progress of tribal clean energy initiatives, this catalytic pooled fund aims to accelerate tribal clean energy projects by financing upfront costs not typically covered by federal funding. With an initial…

Scientists from Singapore have designed new floating breakwaters that integrate wave energy converters that can be used to reduce the impact of waves on offshore PV systems. Their analysis showed that the wave energy systems can achieve the highest additional power when the wavelength is shorter. September 30, 2024 Lior KahanaResearchers from the Singapore Institute of Technology have investigated the performance of new floating breakwaters (FBs) that integrate wave energy converters (WECs).The breakwaters are intended for use in offshore floating PV parks (OFPV). “As the OFPVs move towards the open sea, they are exposed to severe random waves and therefore…

Korean utility KEPCO completed a 978 MW battery project that we billed as Asia’s largest battery energy storage system for grid stabilization purposes. September 30, 2024 Marija Maisch By ESS newsSouth Korean utility Korea Electric Power Corp. (KEPCO) has officially completed construction work on a major battery energy storage project in Miryang City, Gyeongsangnam-do Province.Billed as Asia’s largest battery energy storage system for grid stabilization purposes, the system has a power of 978 MW and a storage capacity of 889 MWh.The ceremony to mark the completion of construction took place on Thursday, September 27, at the 154 kV Bubuk substation…

Tetracene is a polycyclic aromatic hydrocarbon commonly used in organic field effect transistors (OFETs), organic light emitting diodes (OLEDs) or as a sensitizer in chemiluminescence. Singlet fission solar cells can produce two electrons from one photon, making the cell more efficient September 30, 2024 Emiliano BelliniResearchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) plan to use synthesized tetracenedioic acid (Tc-DA) to develop so-called singlet fission solar cells. Tetracene is a polycyclic aromatic hydrocarbon commonly used in organic field effect transistors (OFETs), organic light emitting diodes (OLEDs) or as a sensitizer in chemiluminescence.Singlet exciton fission is an…

In 2024, electricity generation from the US grid has increased by more than 109 TWh through the end of July, which represents a growth of 4.5%. This increase was caused by an increase in methane production of 52 TWh, while solar energy contributed another 36 TWh. September 27, 2024 John Fitzgerald Weaver Image: Ben o’bro, UnsplashBy pv magazine USAThe U.S. Department of Energy’s Energy Information Administration (EIA) has published the September Electric Power Monthly, with data through July 2024.Solar energy generation has increased by almost 26% year on year, with a 1% increase in electricity consumption in July 2024 compared…

A high energy density Mars battery designed for long-duration missions The extreme environmental conditions on Mars, with an atmosphere of 95.32% carbon dioxide and significant temperature fluctuations, pose major challenges for energy storage systems on the planet. To overcome these hurdles, Prof. Peng Tan and Dr. Xu Xiao from the University of Science and Technology of China have developed a new type of Mars battery, which uses the Martian atmosphere as a fuel source during discharge. This innovative battery system minimizes weight, making it ideal for space missions. Once discharged, the battery can be recharged using solar energy collected from…

Another Origis Energy project. Origis Energy and the Tennessee Valley Authority (TVA) have announced a power purchase agreement to expand their solar and storage portfolio in Mississippi. Origis would develop, build and operate Hope Solar + Storage, a 200 MWAC solar + storage facility of 200 MW (800 MWh) in Clay County, Mississippi, and sell the power to TVA to help fuel some of the fastest growth in the country – both in terms of population and economic development. Commercial operation of Hope is scheduled to begin in late 2028, pending completion of all required environmental and development permits and…

In a new weekly update for pv magazineSolcast, a DNV company, reports that August was an exceptional month for solar production in the southeastern states, while regions such as the Midwest and Northeast experienced cloudier conditions and lower irradiance. September 27, 2024 SolcastAugust 2024 was an extraordinary month for solar energy production in the southeastern states. A dominant high-pressure ridge over most of the US, especially over the Southern Plains and southern states, resulted in record-breaking heat and radiation levels, according to analysis using the Solcast API. Meanwhile, regions such as the Midwest and Northeast experienced cloudier conditions and lower…

Research shows how water systems can boost the adoption of renewable energy New research led by Stanford University highlights how water systems, such as desalination plants and wastewater treatment plants, can help make renewable energy more accessible and reliable. The study, published September 27 in ‘Nature Water’, introduces a framework to assess how water systems can adjust their energy consumption to balance supply and demand from the electricity grid. “If we want to reach net zero, we need demand-side energy solutions, and water systems represent a largely untapped resource,” explains Akshay Rao, lead author of the study and a PhD…

Last week National Grid Renewables organized an event celebrate construction from its Unbridled Solar Project in Henderson and Webster Counties, Kentucky. At 160 MW, the project is expected to be the largest solar farm in the state of Kentucky when it goes online in late 2024. The event brought together a wide range of stakeholders including landowners, community members, neighbors and project partners. “It’s exciting to be here today speaking with local residents and neighbors of the Unbridled Project,” said Gemma Smith, VP of field operations at National Grid Renewables. “We are proud to celebrate the significant economic impact the…
