The CAF On Board Energy Storage Systems (OESS-s) will use Skeleton’s graphene ultracapacitor cells for energy recovery, peak shaving and catenary-free applications.

As energy efficiency is now the key design criteria for any public transportation system, ultracapacitors are ready to significantly contribute to the rail industry says CAF, headquartered in Donostia-San Sebastian in Spain

“Skeleton’s cells offer very high efficiency and low heat losses, and their high-power density enables further weight and space savings. Therefore, they are a perfect fit to the rail and tram industry. Adding them to our energy storage systems will greatly benefit our existing and future customers, allowing to maximize energy efficiency at an unprecedented level,” said the company.

“In terms of public transportation, trams are already a very energy-efficient solution. However, our ultracapacitors can take them to the next level allowing the maximum energy recovery,” said Taavi Madiberk, co-founder and CEO of Skeleton Technologies. “We are very glad to now collaborate with CAF Power & Automation and supply our cells to make trams that use their energy storage systems some of the most modern, cost and energy-efficient in the world. Our ultracapacitors are already the most advanced ones on the market but thanks to our curved graphene material, we are planning to increase our advantage even further, offering more reliable, long-life alternatives to high-power batteries.”

Skeleton’s cells will be integrated into Greentech OESS-s, which are already powering trams in dozens of countries including the UK, Australia, Estonia, Luxembourg, and Spain.

Skeleton Technologies has manufacturing in Großröhrsdorf, Saxony, Germany, materials development in Bitterfeld-Wolfen, Saxony-Anhalt and electrical engineering in Tallinn, Estonia.
