Integrating low-temperature heat sources in industrial-scale heat pumps
The Fraunhofer ISE has designed a novel method for assessing the potential of low-temperature heat sources for large-scale heat pumps. The five-step process was tested on the German city of Fellbach, enabling the identification of heat sources with LCOH lower than €0.1/kWh.
France’s top audit body questions feasibility of EDF’s nuclear plans
France’s Cour des Comptes has issued a warning about rising nuclear energy costs. It is urging state-owned utility EDF to reduce its financial risks in international projects.
Global super grids do not necessarily favor deployment of solar power
New research from Sweden has shown that building global super grids across different continents could not necessarily result in increased investments in solar power. The scientists outlined the One Sun One World One Grid (OSOWOG) concept, which advocates the development of a global super grid covering 18 time zones.
PV energy forecasting based on genetic algorithms, dynamic neural network
Scientists in Spain have used genetic algorithms to optimize a feedforward artificial neural network for the prediction of energy generation of PV systems. Genetic algorithms use “parents” and “offspring” solutions to achieve better results in subsequent generations.”
New aluminum-ion battery with unprecedented long cycle life
Researchers in China have reported a breakthrough in the development of aluminum-ion batteries. They have created a solid-state electrolyte that facilitates the smooth movement of aluminum ions, significantly improving battery performance and longevity.
Enphase Energy, Octopus Energy announce smart tariff for UK customers
In an update to the two companies’ strategic partnership, Octopus customers with Enphase solar and battery systems can now benefit from a smart import and export tariff designed to save money on electricity bills.
Teralight switches on Israel’s largest solar plant
Teralight has activated Israel’s biggest PV project, the 150 MW Ta’anach 1 array, which will produce 310 GWh of energy per year. The facility will be expanded next year with the 104 MW Ta’anach 2 installation, featuring 440 MWh of energy storage.
Toshiba unit launches EneHub platform to support renewable transactions
Toshiba Energy Systems & Solutions Corp. has launched its EneHub platform, a web-based service designed to connect renewable energy producers with buyers. It says the solution will facilitate power purchase agreements (PPAs) and simplify energy transactions.
How to power 4G, 5G cellular base stations with photovoltaics, hydrogen
Scientists have simulated a 4G and 5G cellular base station in Kuwait, powered by a combination of solar energy, hydrogen, and a diesel generator. The lowest cost of energy was found to be $0.0714/kWh.
The case for combining pumped-hydro storage with floating PV
Researchers in Italy have analyzed the techno-economic viability of enhancing three pumped hydro plants in Italy with floating PV on the lower basin. They say that, with their wide results, consequences could be extrapolated to similar regions.
