The report suggests that including smaller batteries in the balance sheet could alleviate pressure on the local network. Image: Nottingham City Council. A new report from energy services provider Joulen, formerly the Electric Storage Company, suggests that 0.1% of UK businesses could supply the equivalent power of both Hinkley Point C and 130 grid-scale battery sites by installing battery energy storage. The report, A better battery strategyoutlines four steps the UK government could take to democratize the energy transition. It was modeled on 70 proprietary data sets and scenarios, taking into account optimization opportunities, existing and potential market mechanisms and…

Silicon-free tandem solar cells are a research topic for commercial, academic, and institutional laboratories in the United States. Researchers at the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) have published a roadmap for tandem technology in the journal Joule including emerging all-organic, all-perovskite tandem combinations and cadmium telluride (CdTe) and copper-indium-gallium diselenide (CIGS) devices.Multiple teams in the United States have announced laboratory-scale fully thin-film cells with conversion efficiencies greater than 27%. “Tandems made entirely of thin film are a logical place to go eventually,” says Andries Wantenaar, solar energy analyst at market intelligence company Rethink Research. “Universities…

In the quest for more sustainable and cost-effective home energy solutions, solar water heating systems have emerged as a powerful and efficient technology. By harnessing the sun’s abundant energy, these systems can significantly reduce both your carbon footprint and your energy bills. Understanding Solar Water Heating Solar water heating systems, also known as solar thermal systems, use the sun’s energy to heat water for domestic use. Unlike solar photovoltaic (PV) panels that convert sunlight into electricity, solar thermal systems directly use the sun’s heat to warm water. This process is highly efficient, often converting 60-70% of the sun’s energy into…

EDF Renewables, Kowepo and Masdar have secured financing to build a 1.5 GW solar power plant near Abu Dhabi, backed by a 30-year power purchase agreement (PPA) with Emirates Water and Electricity Co. September 19, 2024 Patrick Jowett EDF Renewables, Korea Western Power Co (Kowepo) and Masdar have unveiled plans to build a 1.5 GW solar power plant near Abu Dhabi.The project has received financing from six banks and financial institutions: BNP Paribas, Credit Agricole CIB, Standard Chartered Bank, HSBC Middle East, Sumitomo Mitsui Banking Corp. and Export-Import Bank of Korea.A project company – jointly owned by EDF Renewables and…

JinkoSolar wants to expand its activities throughout Africa JinkoSolar, the largest global solar panel manufacturer by shipment volume, is making plans to expand its presence in Africa, focusing on both the solar and energy storage markets. Over the past three years, JinkoSolar has supplied 5.2 gigawatts of solar panels and 100 megawatt hours of energy storage systems to 45 African countries, accounting for 15 percent of the continent’s market share, said Qian Jing, vice president of JinkoSolar. “The company has expanded its local presence by establishing subsidiaries in key markets such as Egypt, Kenya, Namibia, Morocco, Nigeria and South Africa,…

Researchers from TU Delft have modeled a variety of floating PV structures at sea to reveal the design parameters that influence sustainability and yield. September 19, 2024 Valerie ThompsonUsing a multiphysics framework that integrated mechanical and optoelectric properties of offshore floating PV systems, researchers from TU Delft in the Netherlands investigated structural loads experienced by a variety of floating PV structures and the associated electrical power losses .“Simulations like the one we ran shed light on which configurations perform best before being implemented in a pilot system,” corresponding author Alba Alcañiz Moya said. pv magazinenoting that the model allows for…

This year’s edition of the China International Energy Storage Expo (EESA EXPO) has highlighted the latest energy density achievements in battery energy storage, both at the cell and system levels. Meanwhile, the sheer number of commercial and industrial (C&I) systems on display spoke to a growing demand in this market segment. Alternative lithium-ion batteries were not easy to find. September 18, 2024 Marija Maisch By ESS newsSome may argue that China’s commercial and industrial (C&I) battery energy storage market went bankrupt before it took off, but the wide variety of solutions designed specifically for this market segment and showcased at…

It took eight years of field measurements before researchers at RWTH Aachen University in Germany were able to estimate the usable capacity of home battery energy storage systems and develop a data set spanning 106 system years and 14 billion data points. Their key finding was that home battery systems lose on average around two to three percentage points of usable capacity per year, which means good news for the industry as most of the market’s guarantees can be met through the implementation of capacity reserves. September 19, 2024 Marija Maisch By ESS newsAlthough the residential battery energy storage market…

The Hellenic Association of Photovoltaic Energy Producers (Spef) is urging the Greek government to stop issuing new grid connection permits for renewable energy systems to tackle the escalating power curtailment problem in the country. September 18, 2024 Ilias TsagasGreek trade association Spef has asked the national government to halt new permits for large-scale PV installations to curb the increasing clampdown.This is what a spokesperson for Spef says pv magazine that Greece curtailed around 500 GWh of solar energy from January to August, compared to 224 GWh of curtailed energy in 2023.Energy storage is a potential solution to Greece’s electricity constraint…

Data collected by battery storage developers shows that some battery locations are skipped 90% of the time during limited periods. Image: Zenobe. A coalition of battery energy storage developers says skipping restrictions will “hold back investment and drive up consumer bills.” In a letter to the UK government and the ESO before it becomes the National Energy System Operator (NESO), developers including Field, Harmony Energy Zenobē and Eelpower say that ESO is consistently underusing (“skipping”) batteries in its attempts to deal with with the energy oversupply. Even if batteries are the cheapest and fastest way to meet the demands of…
