India-based energy storage company GoodEnough Energy says it has commissioned a 7 GWh battery energy storage systems (BESS) plant in Noida, with plans to expand capacity to more than 25 GWh over the next three years. January 21, 2026 Uma Gupta By pv magazine India GoodEnough Energy has commissioned a 7 GWh BESS plant in Noida, which the company describes as the largest such plant in India. The factory, established with an investment of over INR 450 crore, is now operational. The company said it plans to expand the facility’s capacity from 7 GWh to more than 25 GWh over…

Octopus Energy and state-owned renewable energy company Masdar have announced a partnership they claim will power “the next generation of data centres” in Britain. The companies signed a Memorandum of Understanding (MoU) during Abu Dhabi Sustainability Week in the UAE last week, which aims to optimize the UK distribution network to “unlock hidden capacity”. Octopus’ technology arm, Kraken, will plan to use its optimization technology to dynamically balance on-site generation, battery energy storage systems (BESS), and grid power to “guarantee” power supply to data centers. The company said it would locate these systems around “areas of available capacity” in the…

The pilot features a reversible solid oxide fuel cell battery and represents the first fully containerized, modular ultra-LDES system that can operate for thousands of hours, achieving an energy storage capacity of more than 200 hours. January 21, 2026 Marija Maisch No. 1 power block, No. 2 charging tank and No. 3 drain tank Image: Afternoon energy By ESS news California-based Noon Energy has announced the successful operation of its first pilot system demonstrating ultra-long duration energy storage (ultra-LDES) with a capacity of more than 100 hours. The pilot features a reversible solid oxide fuel cell battery and represents the…

Earlier this month, Duke Energy Florida unveiled its DeBary Hydrogen Production Storage System in Volusia County, Florida, a system that can produce, store and burn up to 100% green hydrogen. A ribbon cutting ceremony for the DeBary Production Storage System was held on January 7. Duke Energy Florida This system is located at Duke Energy Florida’s existing DeBary solar site, which provides energy for two electrolysis units that separate water molecules into oxygen and hydrogen atoms. The resulting oxygen is released into the atmosphere, while the green hydrogen is delivered in reinforced containers for safe storage. At times when energy…

The Japan Photovoltaic Energy Association (JPEA) has released a voluntary reference guide to support the adoption of vertical bifacial PV in Japan, outlining design, performance and compliance considerations for projects in high snow conditions, high latitudes and limited space. January 21, 2026 Brian Public Japan’s leading solar industry group has given a major boost to the adoption of vertical bifacial PV with the publication of a new voluntary reference guide. The JPEAs vertical two-sided solar guide provides practical guidance for investors, engineers and project developers in a format that is still largely unknown in Japan. This move underlines JPEA’s strategic…

US scientists used density functional theory to reveal how sodium ions are stored in nanoporous carbon anodes for sodium ion batteries, identifying dual ionic and metallic storage mechanisms in the pores. Their findings provide practical design guidelines to improve battery voltage, safety and commercial viability of stationary energy storage. January 21, 2026 Emiliano Bellini Researchers from Brown University in the United States have investigated the behavior of sodium storage in carbon materials used in sodium ion batteries, with the aim of improving their commercial viability for stationary renewable energy storage applications. “Our work provides guidance for synthesizing anode materials that…

While global corporate financing for solar fell to the lowest level since 2020 in 2025, the number of deals rose to the highest level since 2017. According to Mercom Capital Group, investors favored smaller, less risky, execution-ready projects last year amid policy uncertainty, trade pressure and higher financing costs. January 21, 2026 Patrick Jowett Global corporate financing in the solar sector totaled $22.2 billion through 175 deals in 2025, according to data published by Mercom Capital Group in its Annual Report on Solar Financing and Mergers and Acquisitions 2025. The total investment figure, which includes venture capital financing, public market…

Energy storage company Zenobē is currently legally challenging the LDES (Long Dur Energy Storage) cap program, claiming it unfairly favors LDES technologies. The company took the case to the Competition Appeal Tribunal in late October 2025, after previously raising public concerns about the design of the cap and floor scheme. Court documents show the company claims the plan’s design “threatens to distort competition” by pitting subsidized LDES projects against unsubsidized lithium-ion BESS projects.Zenobē told the Tribunal that by giving subsidized LDES projects access to the same markets as established short-term technologies, Ofgem risked “creating an uneven playing field that undermines…

DEC’s ‘Dongchu No. 1’ prototype completed more than 100 charge-discharge cycles at 65 meters depth in a freshwater lake. January 21, 2026 Vincent Shaw Image: China Dongfang Electric Corporation (DEC) By ESS news Dongfang Research Institute, a subsidiary of China Dongfang Electric Corporation (DEC), has announced the completion of a 10-day full-scale underwater trial of China’s first submerged energy system with kilowatt-scale pumped storage, marking a step forward in the development of alternative long-term storage technologies in the country. The system, branded ‘Dongchu No. 1’, was tested in Minhu Lake in Sanming, Fujian Province, at a water depth of 65…

The three new utility-scale projects in Region Ten of Guyana, with a combined capacity of 15 MW, are part of broader plans to deploy 33 MW of large-scale solar power with associated energy storage in four of the country’s regions. January 21, 2026 Patrick Jowett Image: Oskar Kadaksoo, Unsplash The government of Guyana has unveiled plans for three utility-scale solar farms in region ten of the country with a cumulative capacity of 15 MW. The three projects, worth $22.6 million, consist of a 3MW, 4MW and 8MW solar array that will be built on separate sites and will be supported…
