Why lithium-ion is NOT the new silicon

To date, the vast majority of the entries into the energy storage market have depended on lithium-based battery chemistry, but, the idea that lithium-ion is the technological and economic front-runner in the stationary storage space is a myth that is in dire need of de-bunking, claims Ron Van Dell.

The hope invested in rural microgrids deserves better returns

Microgrids—distributed systems of localised generation, distribution network and load—are being increasingly deployed particularly in rural areas of emerging and under-developed countries to achieve energy access. However, a “fragmented and unorganised” sector still faces significant challenges, writes Harsh Thacker.

Transforming the market for virtual power plants with advances in energy storage

From the outside, the VPP looks like a single power production facility that publishes one schedule of operation and can be optimised from a single remote site. From the inside, the VPP can combine a rich diversity of independent resources into a network via the sophisticated planning, scheduling, and bidding of DER-based services. Peter Asmus examines the role energy storage can play within this architecture.

Where micro-grids, emerging markets and flow batteries intersect

Energy storage could have a ‘highly critical’ role to play in emerging economies, Aloke Gupta of Imergy Power Systems says. Gupta, who was previously with California’s Public Utilities’ Commission, the state’s regulator, talks about the uses and applications of micro-grids, from his vantage point of view as a flow battery and storage system maker.
