Researchers at the solar-cell technology institute Helmholtz Zentrum Berlin (HZB) have developed a tandem solar cell that converts 32.5% of incident solar radiation into electrical energy – a world record. Tandem solar cells increase the efficiency of a solar cell by splitting the spectrum and optimizing each section of the spectrum. The European…

Despite Russia’s ongoing invasion, Ukrainian energy company DTEK Group has finished the construction of the first 114 megawatts (MW) of a 500 MW wind farm. In the spring of this year, 19 Vestas 6 MW wind turbines will begin to generate 114 MW of electricity. The Tyligulska wind farm, which is in the Mykolaiv region in…

The pace of clean technology rollout is set to put the EU at 45% renewable energy by 2030, according to new analysis from energy think tank Ember. That exceeds the 40% target originally set in the Fit-for-55 package. The European Climate Foundation summarizes what the Fit-for-55 package is: Released in two batches in July…

Energy storage developer NRStor has announced that the Independent Electricity System Operator (IESO) has entered into an Energy Storage Facility Agreement (ESFA) for its Oneida Energy Storage Project. With the finalization of the ESFA, NRStor has finalized and executed a battery supply agreement with Tesla, and an engineering, procurement, and construction (EPC) agreement with Aecon…

Wind, solar, and batteries make up 82% of 2023’s expected new utility-scale power capacity in the US, according to the US Energy Information Administration’s (EIA) “Preliminary Monthly Electric Generator Inventory.” As of January 2023, the US was operating 73.5 gigawatts (GW) of utility-scale solar capacity – about 6% of the country’s total. But solar…

Atlis Motor Vehicles has debuted the design of its AC/DC charge handle and charging cable, capable of delivering up to 1.5MW of power. The Atlis team says it has successfully delivered greater than 1,000 volts and more than 1,200 amps of electric current through the cable while maintaining a temperature below 30 degrees Celsius (86…

Princess Elisabeth Island, a pioneering electricity grid at sea, connects offshore wind farms to the mainland, and it also creates connections with neighboring countries. The Princess Elisabeth Zone is a future 3.5 gigawatt (GW) offshore wind farm that will be in the North Sea, almost 45 km (28 miles) off the coast of Belgium.…

Toyota Motor North America (Toyota) and Oncor Electric Delivery (Oncor), a Texas-based electric transmission and distribution company, have agreed to collaborate on a pilot project around vehicle-to-grid (V2G), a technology that allows vehicles to flow energy from their battery back onto the electric grid. The effort will be led by Toyota's Electric Vehicle Charging Solutions…

Swedish power giant Vattenfall did a two-year, €3 million study of seabirds at an offshore wind farm off Scotland – here’s what it found. The aim of the 115-page study, which took place at Vattenfall’s 11-turbine Aberdeen Offshore Wind Farm, aka the European Offshore Wind Deployment Center, was: …to improve our understanding of…
