Bankable and insurable energy storage: a necessary next step for renewable energy

The rapid acceleration in energy storage deployment expected over the coming years will require innovation in the quality and safety standards underpinning new battery and associated technologies. VDE’s Jan Geder looks at the technical work underway to ensure the coming storage boom has firm bankability and insurability foundations.

Case study: Using batteries to reduce the impact of grid maintenance

Batteries are increasingly widely used in grid balancing, but there are many more applications where a battery can play an important role. With electric grids requiring periodic maintenance, batteries can stand in for the grid during downtime in order to reduce the impact on industry and households, writes Dieter Castelein.

SPONSORED: The ‘new animals’ of the grid: why energy optimization is your best investment

A new white paper from Wärtsilä Energy shows that being able to integrate and then optimise all of these different assets is the key to ensuring that your project - and your investment - is going to provide the maximum benefit, longest possible lifetime in the field - and the best business case. Risto Paldanius, Director of Business Development, Energy Storage and Integration at Wärtsilä told us a bit more about what optimization really means in today’s energy market.
