Researchers in South Korea have successfully demonstrated the use of free ambient air as a fuel, using a sodium-based solid electrolyte to tackle the carbonate problem holding back the rollout of metal-air batteries. Their sodium-air battery cell has demonstrated high efficiency, increased energy density and a wide voltage range. June 4, 2024 Marija Maisch Battery diagramImage: Pohang University of Science and Technology (POSTECH), Nature Communication, Common License CC BY 4.0From pv magazine ESS news placeMetal-air batteries, using lithium or sodium, have been of great interest because of their exceptionally high theoretical gravimetric energy densities. These batteries rely primarily on the…
The PDR revision removes the 50 kW upper limit for permitted solar rights on roofs of domestic and non-domestic buildings. Image: SolarEdge The Scottish Government’s review of Permitted Development Rights (PDRs) for rooftop solar has officially come into effect, eliminating the need for planning permission. The long-awaited legislation is expected to have a “real significant benefit for business and commercial rooftops to help reduce energy costs”, according to Solar Energy UK, with the PDR revision removing the 50 kW upper limit for permitted rooftop solar allowances on domestic and non-urban area. domestic buildings. Solar Energy UK also announced that the…
The European Commission says it has started work on a new pilot mechanism, and Italy has agreed to expand cooperation with Austria and Germany, while supporting cooperation between Italian companies and Finland’s Wärtsilä. June 4, 2024 Sergio Matalucci Kadri SimsonImage: EC – Audiovisual service, Jennifer Jacquemartthe European Commission has started work on a pilot mechanism to collect, process and make accessible information on the supply and demand of renewable, low-carbon hydrogen and derivatives, to support the continent’s hydrogen market. “The new mechanism has been created under the recently adopted low-carbon gases and hydrogen package And aims to accelerate investments by…
It’s quite something to unexpectedly find yourself in the eye of the storm. One day I was CEO in a niche sector, the next day I was in the middle of a heated public debate. My sector, the Voluntary Carbon Market (VCM), and my former organization work with carbon credits and set standards for their generation. Over the 25 years I have worked with carbon credits, I have witnessed the evolution of perceptions about this once small but innovative climate solution becoming increasingly polarized – with market stakeholders arguing that carbon finance is diverting critical funding to important mitigation efforts…
American farmers reported increased interest in leasing land for solar energy production, according to the monthly magazine Purdue University/CME Group Ag Economy Barometer Table of contents. In addition, views on agricultural land values also saw a boost thanks to clean energy production at agricultural sites. This month’s Ag Economy Barometer survey was conducted May 13-17.The index shows that interest in leasing agricultural land for solar energy production is increasing, according to recent research results. In both April and May, about 20% of respondents (compared to just 12% in March) discussed leasing agricultural land for solar energy production in the past…
China’s National Energy Administration (NEA) says the utilization rate of solar and wind power projects in specific provinces should not fall below 90%. June 4, 2024 Vincent Shaw Image: Jason Blackeye, UnsplashOn June 4, the National Energy Administration (NEA) of China has issued new rules to determine the target for renewable energy use in each of the country’s provinces. This policy adjustment is intended to enable China’s provincial power grid operators to increase the curtailment threshold for wind and photovoltaic energy from 5% to 10%. The NEA said that in areas with favorable resource conditions, the requirements for the renewable…
Numerical weather forecasting company (NWP) Climavision has released its new one Horizon AI range of products for the sustainable energy sector. The company has steadily expanded the application of machine learning and AI to increase the accuracy and reach of its prediction models. Now, with the recent acquisition of Intersphere, provider of AI-driven sub-seasonal to seasonal (S2S) forecasts, Horizon AI will fully integrate Climavision’s offering. “Bringing a complete range of solutions like this to market is an important development for the industry and for our customers, but it is a very natural step for us as a company,” said Chris…
Chinese polysilicon producer GCL Tech says it is working with state-owned Mubadala Investment Co. from the Emirates to build the Middle East’s first polysilicon factory in the United Arab Emirates. June 4, 2024 Emiliano Bellini GCL Tech said it has signed a strategic partnership agreement with MDC Power, a unit of UAE-based Mubadala Investment Co., to build a polysilicon manufacturing facility in the United Arab Emirates.GCL Tech did not reveal the location of the factory, which will be the first polysilicon production facility in the Middle East.“The company expects to continuously develop the partnership with Mubadala with a view to…

Cumberland Council has granted planning permission for a 200MW/400MWh BESS project from developers Recurrent Energy and Windel Energy, which will not start construction until 2029 unless a new grid connection date is agreed. The two-hour Harker project is located between the villages of Todhills and West Linton on the outskirts of Carlisle and will be connected to the Harker National Grid Substation via an underground 400kV cable. Construction is expected to begin in…
The German research institute said the new heat pump was developed in collaboration with ZAE Bayern and Mafac E. Schwarz. The system uses propane (R290) as a refrigerant and is suitable for industrial processes with a temperature range of 50 C to 70 C. June 4, 2024 Emiliano Bellini Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) has unveiled a new heat pump intended for use in industrial processes with heating and cooling requirements.The German research institute said it developed the system in collaboration with the Bavarian Center for Applied Energy Research (ZAE Bayern) and Germany-based industrial equipment supplier…
