Interview: Behind Spanish island’s ‘100% renewable energy’ project headlines

The International Renewable Energy Association (IRENA) recently released its electricity storage technology roadmap, looking at how electricity storage can support the increased deployment of renewable energy.

The roadmap highlighted the necessity of electricity storage in remote areas and on islands, but also cited this as an economic opportunity.

For some time IRENA and other experts have said that islands could act as test cases and models for energy storage in the wider market.

Last week, PV Tech Storage reported that Spain’s El Hierro, the most southerly of the Canary Islands, managed to use a combination of only wind, hydro and energy storage to meet the energy needs of all of its 10,000 locals for a total of four hours.
