Energy Storage

Solar manufacturers Longi and Tongwei have frozen next month’s prices.

Engie’s storage subsidiary has unveiled its hydrogen-based energy storage system, built with its proprietary technology, in Agkistro, Greece.

Industrial and academic partners are developing a battery inverter which can be grid connected under normal operation but can also use nearby renewables generators to form an island grid, for whole-area uninterrupted power supply.

The plan envisages to reach a 30% share of renewable energies in the country’s electricity mix by 2030. An intermediate target of 20% has been set for 2025.

The energy company has invested €33 million in UK-based electrolyzer maker ITM and has started a cooperation with the Italian railway operator to test joint hydrogen solutions for transport.

The French authorities have launched two tenders for projects, in line with a new national plan to develop carbon-free hydrogen, announced Sept. 8.

The proposed 26 GW Asian Renewable Energy Hub in Western Australia gained federal government support last week. Construction is expected to start in 2026.

Analysts at Mercom Capital Group have tallied up corporate funding, venture capital and debt and public market investment for battery storage, smart grids and energy efficiency companies. From a financial perspective, the industry appears resilient to the Covid-19 crisis and ready to grow further.

Swedish scientists have developed a redox flow battery with polymer electrodes, based on a special conductive polymer known as PEDOT. The battery features a water-based electrolyte based on a solution of redox quinone molecules, which can be extracted from forest-based materials.

The pilot project, consisting of a 50 MW solar plant and a utility scale electrolyzer, is planned to test how this combination may help reduce grid constraints in the country.
