Grids & Integration

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.

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 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 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.

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.

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.

Conceived by an international research team, the model can also be utilized for hybrid wind-solar projects. According to its creators, it provides a practical solutions for land-use optimization and renewable energy planning.

The researchers conducted a case study on a solid oxide fuel cell system deployed in a nearly zero-energy single-floor villa with a size of 80 m2 located in southern Italy. They found that, in particular conditions of photovoltaic production, the system is not only able to meet the home electric loads, but also to inject surplus energy into the network.

China is building its first gigawatt-scale residential virtual power plant (VPP) in Jiangsu province. The project will connect millions of high-power household appliances to a cloud-based energy pool to improve grid stability and boost renewable energy use.

A group of scientists has developed an open-source dataset comprising three years’ worth of data from Hong Kong’s largest behind-the-meter rooftop solar power project. Power generation was collected at 5-minute intervals, and meteorological data at 1-minute.
