Electric car start-up Rivian starts Second-Life battery project-start-up

The electric car start-up Rivian Automotive and the Honnold Foundation work together as part of an initiative to use Second-Life batteries as stationary energy storage in a Microgrid project in Adjuntas, Puerto Rico. This is a big step for Rivian, which wants to expand its business activities beyond the production of fully electric luxury adventure vehicles.

Rivian is used for the upcoming energy storage project, which is to start in 2020, expanded 135 kWh battery packs from its developing vehicles. A similar project have recently launched Audi and The Mobility House in Berlin on the Euref-Campus. Rivian has designed its battery packs and modules so that at the end of their vehicle life – at about 70 to 80 percent of their original capacity – can be removed from the cars and installed in a stationary energy storage.

Second-Life batteries are an important factor for accelerating the distribution of renewable energies. It is exciting to imagine that this system makes an important contribution to a community. With this project, we can model a tailor-made energy storage solution that takes into account space restrictions, reliability and energy independence.”- Robert” RJ “Scaringe, founder and CEO of Rivian

The use of older batteries for energy storage is a clever and sustainable way to extend the cells from recycling extensively. While batteries at the end of their vehicle life have a certain wear compared to new electric cars, they can still work for a few years (experts even from more than 20 years off) as stationary energy stores.

Emergency stream for Hurricanes threatened city

Rivian and the Honnold Foundation chose Adjuntas, Puerto Rico, as a location for their microgrid project, which is partly due to the city of help urgently needed. Adjuntas was hit by Hurricane Maria in 2017, and the community has been fighting for a functioning power supply since then. In case of success, the Microgrid initiative of Rivian and Honnold could help many companies in the city. Residents could also rely on this reserve stream if power failures occur.

Adjuntas is a city with 20.000 inhabitants in the middle west of Puerto Rico. Hurricane Maria has hit the island difficult in 2017. In view of the increasing frequency and severity of the storms by climate change, the NGO Casa Pueblo of Adjuntas endeavors to find a robust and affordable source of municipal power supply.

The battery engineers of the Honnold Foundation and Rivian visited Casa Pueblo early 2019 to meet with the responsible persons of the community. Together, design a site-specific system that will supply many companies near the central main square of Adjuntas with electricity. The compensation of daily electricity bills also reduces the high commercial energy costs, which are twice as high in Puerto Rico as in the national average.
