Commercially viable energy storage has the potential to change the game by solving the energy trilemma. Arshad Saleem, from KIC InnoEnergy, which invests in and supports European sustainable energy, says marrying start-up innovation and big business experience could accelerate the journey to viability.
For over a decade, net metering has been a crucial component of the economic puzzle for renewable energy, allowing both residential and commercial rooftop PV owners to realise favourable returns on their solar equipment investment. John Merritt of Ideal Power Conversion looks at some of the arguments and counter-arguments and says solar-plus-storage could be the natural successor to the policy - starting at commercial and industrial (C&I) level.
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.
The anticipated growth in stationary energy storage will be dependent on a significant decrease in costs. Florian Mayr and Hannes Beushausen explain how the relative costs of different storage technologies in different applications can be compared and understood as an intial step towards increasing competitiveness.
Battery energy storage used on the grid for ancillary services has been gaining momentum ever since the United States changed its frequency regulation markets by introducing a concept known as pay-for-performance. Roger Lin of NEC ES takes a good look at how this space is evolving, as the UK’s National Grid prepares a 200MW tender for enhance frequency response.
