Axion Power International, focusing on “hybrid battery technology” that combines lead acid with the properties of carbon-based supercapacitors, has warned that it is in financial trouble after failed attempts to commercialise its devices.

A containerised flow battery dubbed the ‘largest’ such system in the US has been matched for size by another system dedicated last week in Snohomish, Washington.

On-board batteries are the way of the future. Energy storage is the right approach to make energy systems on board ships more intelligent and efficient. Energy storage systems can be especially beneficial on vessels with a widely fluctuating fuel consumption profile. Nidec ASI discuss two recent projects to bring battery storage onto such vessels.

Compressed air energy storage plants could be rolled out across Canada from energy storage project developer NRStor and advanced adiabatic compressed air energy storage (A-CAES) firm Hydrostor.

Brisbane-based renewable energy investor Lyon Group will soon start building a AU$1 billion (US$767 million) solar-plus-storage farm in South Australia – the world’s largest.

Belectric has developed PV plants on every continent of the globe except Antarctica and also delivers energy storage system projects and offers a wide range of energy storage solutions including in-house battery systems, turn-key large-scale battery storage as well as scalable container solutions. Managing director of Belectric Solar and Battery, Frank Amend, spoke to Energy-Storage.News about the company’s recent acquisition by RWE subsidiary innogy and where the company sees energy storage (and solar) going.

Flow battery manufacturer ViZn Energy Systems has won a contract to provide a 1MWh zinc-iron flow battery to India’s majority network operator and utility Power Grid Corporation of India Limited (PGCIL).

The UK’s energy regulator has taken what appears to be an encouraging viewpoint on “double charging” of energy storage, clarifying the definition of the technology’s role in the grid, according to one expert view.

Solarwatt has unveiled the latest evolution of its MyReseve system, a fully modular storage system that can be customised to suit the demands of any application.

The German state of North-Rhine Westphalia looks set to go ahead with a 200MW pumped hydro energy storage project in a coal mine, as well as a smaller energy storage demonstration project which includes a flywheel from Stornetic.
