Sales of battery storage units to residential households in Germany are booming, but it’s the value of services the batteries can provide, rather than the hardware itself that offers a long-term economic opportunity, a Siemens representative has said.

It’s been predicted for some time that the redox flow energy storage space will, after some turmoil and rapid consolidation, find success in providing energy storage at durations of more than four hours. This past couple of weeks have been a tale of both turmoil and success.

The European Council (EC) has agreed a new position on the internal electricity market, placing consumer empowerment, cross-border trading and higher levels of renewables at the heart of the European Union’s efforts to transition to a low carbon economy.

Research firm IHS recently reported that as of the end of 2015, there was a global pipeline of 1.6GW of battery or flywheel-based grid storage projects in place. Andy Colthorpe spoke to principal analyst Marianne Boust, who explained why last year truly saw a “change in stakeholder mentality” in favour of energy storage and why 2016 will be another record-breaking year.
