Power to charge up the energy transition

A solution in the making, coupling sustainability and circular economy

Storage is undergoing a transition, as its usage is to be regulated by a gradual and case-specific approach, guaranteeing the safety, sustainability and economic soundness of the whole system. 

Basically, it all boils down to the end-of-life management that will need for transparent reuse and recycling processes to be put in place. This is the reason that prompted us to define specific sustainability indicators that drive the entire supply chain in adopting a “design-to-recycle” approach for their products. 

Moreover, we’re currently examining the feasibility of integrating former EV batteries in renewable power plants to provide storage services to the power grid while building the virtuous process also known as the circular economy.

Along these lines of development did the “Second Life Melilla” come to life, as it was selected by the World Economic Forum (WEF) as a member initiative. The system will support the grid’s stability by harnessing power from former Nissan Leaf battery packs.

At the same time, we’re considering possible “green” engineering solutions to define future storage systems, driven by a solid commitment and partnerships with some of the leading suppliers in the business. Among the latest cutting-edge operations we’ll test on our power stations is a thermal storage system developed by Brenmiller - an Israeli energy startup - and designed to stockpile high-temperature energy by using crushed rocks as a means to conserve energy in the form of extreme heat. Furthermore, two long-term storage systems - one based on a flux battery and the other on solid-state Lithium batteries - are being integrated in a newly built solar park in the Balearic island of Mallorca. This trio of innovative solutions is the backdrop to our Innovation Team as it helps suppliers in adapting as much as possible their infrastructure to the specific needs entailed by the energy transition, while setting the stage for widespread use of these technologies to improve Enel’s future competitiveness.
