In Europe, and around the world, renewable electricity generation is being built at pace. However, these sources of energy create a new challenge: they are intermittent, and will not generate power on dark, windless days.

One solution to the challenge is to install grid scale storage. If you’re building an offshore wind farm, with a view to serving distant industrial centres, megawatt- and gigawatt-scale storage may be the answer. 

But much of our energy use happens in the home, or in smaller businesses. Often, with the growth of domestic solar, the power we use in our kitchens is balanced by that generated on our rooftops. As energy supply and demand is increasingly distributed, wouldn’t it make sense to also make use distributed storage?

That’s the question that Mattia Secchi of the Technical University of Denmark is trying to answer. Many of us already have plenty of battery storage available in our electric cars. But these will require the adoption of standardised bidirectional charging, and new metering and grid technology. His work, and that of his colleagues, models community-based V2G, establishing how distributed storage can bring benefits across the economy.
