China’s Livoltek says it has developed 120 kW electric vehicle chargers with 140 kW input and 100 kWh LFP battery, supporting CHAdeMO, GB/T, CCS1 and CCS2 standards. September 23, 2024 Lior KahanaChinese inverter and battery manufacturer Livoltek has released a new electric vehicle charger with energy storage functionality.The BESS120 DC charging station has a power of 120 kW over two connectors and an input power of 40 kW. It has a 100 kWh lithium iron phosphate battery (LFP).“One of the standout features of this charger is its wide operating voltage range, which extends from 200 to 1,000 V DC,” the…

The Association of Solar Energy Industries (SEIA) released a draft industry standard to increase transparency of the solar and storage supply chain and help companies comply with U.S. Customs and Border Protection (CBP) traceability requirements. Standard 101 provides a section that manufacturers and importers can follow to trace the origin of products, from raw materials to finished products. The standard is based on real-world examples of solar product shipments detained and released by customs officials and includes input from manufacturers, developers and third-party auditors. “The U.S. solar and storage industry has an unwavering commitment to ethical business practices,” said Abigail…

Tokyo-based heavy industry manufacturer IHI Corporation has created a thermal utilization system that can convert excess direct current at solar power plants into carbon-free steam. A test project that started in April has consumed all the electricity generated and is running stably, the company said. September 23, 2024 Patrick Jowett Japan’s IHI Corporation says a pilot of a thermal utilization system that converts all previously discarded excess direct current (DC) at solar power plants into carbon-free steam has “demonstrated stable system performance.”IHI says the Renewable Energy Thermal Utilization System economically and flexibly converts renewable electricity into thermal energy and stores…

Researchers in Italy have devised a dual-source heat pump system that uses both a fin coil evaporator and a solar evaporator made with three photovoltaic thermal panels. The combined operation of the two evaporators allows the heat pump to achieve a higher evaporation pressure and coefficient of performance. September 23, 2024 Emiliano BelliniResearchers from the University of Padua in Italy have designed a dual-source heat pump using CO2 as a coolant and a solar evaporator consisting of three PV-T collectors“The main innovation lies in the combined operation of two evaporators, the fin coil and the PV-T collectors, allowing a choice…

Flexbase plans to build a 500 MW redox power storage project in Laufenburg in early 2025. September 23, 2024 Marian Willuhn By ESS newsA redox flow energy storage facility with a capacity of 500 MW will be built in Switzerland. The development was announced by the company Flexbase, which said the project will be built in Laufenburg, a city on the Rhine that is partly in Switzerland and partly in Germany.Unlike the lithium-ion batteries commonly available on the market, redox flow batteries cannot burn and do not degrade. Flow batteries also do not require critical raw materials such as lithium…

How solar energy keeps a California community alive as the ground shifts The cliffs of the Palos Verdes Peninsula have always been breathtaking and offer beautiful views of the Pacific Ocean. But beneath the natural beauty of Portuguese Bend, a slow and terrifying force is at work. Here, in one of the most geologically unstable areas in California, the ground is constantly moving. The land is sliding into the sea at a rate of a foot a week, threatening every inch of homes and lives. The Portuguese Bend landslide, once a slow-moving anomaly, has become a full-scale disaster, and the…

The Hungarian company said its new products can handle a load of 300 kg. The modules are available with a power of 23.65 W and 59.68 W and can be integrated with wood-plastic composite, wood, stone or ceramic floors. September 23, 2024 Lior KahanaPlatio Solar, a Hungarian green technology company, has announced a new range of walk-on photovoltaic panels.“Solar Deck transforms outdoor spaces such as terraces, rooftops, marinas and event spaces into efficient, energy-generating surfaces,” the company said in a statement. “It is a patio covering solution that can be integrated with wood-plastic composite (WPC), wood, stone or ceramic floors…

The Greek government decided to auction 100 MW less capacity than initially requested and to offer more money to the awarded projects than expected. September 23, 2024 Ilias Tsagas By ESS newsThe Greek government on Friday published details of the country’s third standalone, front-of-the-meter grid-scale battery energy storage auction.The auction aims at 200 MW of battery storage capacity, 100 MW less than initially requested when the subsidy program for this form of energy storage was announced.The auction must be completed by December 15, 2024 and the awarded projects must be connected to the electricity grid by April 30, 2026, according…

Firebrick heat storage technology, not batteries, will be used to store energy for industrial process heat in a 100% renewable energy system, says a Stanford University study. September 23, 2024 William DriscollBy pv magazine USAHeat storage from refractory bricks for industrial processes could replace approximately 14% of battery capacity globally by 2050 in a 100% renewable energy system, compared to a baseline scenario without refractory bricks. a study by Stanford professor Mark Jacobson and three Stanford colleagues.Firebricks are made from common materials and the cost of a firebrick storage system is less than one-tenth the cost of a battery system…

From pv magazine July-August 2024Sometimes things just click. In Chile, market conditions seem perfectly poised for a step change in the number of hybrid projects combining renewable energy technology. The timing couldn’t be better for a country struggling with a growing austerity problem. In Chile, around 1,911 GWh of excess renewable electricity was curtailed in the first five months of 2024, representing a 159% increase in electricity waste compared to the same period of 2023, according to figures from Acera, the Chilean renewable energy association.At the same time, solar energy generation capacity has grown explosively and has more than doubled…
