Energy Storage
Energy drives all processes.
Producing and using energy efficiently
and cleanly is essential to our future.
Our technology will reduce waste within the existing energy infrastructure, and unlock the potential of renewables for a sustainable future.
Less than 1% of the daily energy used in the US can be stored on the grid.
95% of this storage is pumped hydroelectricity, a legacy technology where excess energy is used to pump water uphill to a reservoir, for later release through a hydroelectric generator.
This is very geographically limiting.

We aim to bring widespread
electrochemical storage to the grid
for use anywhere, anytime.

XL Batteries and Stolthaven Terminals announce a partnership to develop an industrial-scale flow battery.
“While there has been significant focus on renewable power generation there has been less focus on long-term energy storage, which is critical for the global transition to ‘greener’ energy alternatives. Stolthaven Terminals has been working on finding a partner in electrochemical storage and in XL Batteries we have found one that shares our vision to use innovation and skills partnerships to develop energy solutions for the future.”
– Guy Bessant, President, Stolthaven Terminals

XL Batteries welcomes Bart Riley as Chief Commercialization Officer. Bart is leading the transition of XL Batteries’ novel technology from prototype to market. Bart was the co-founder and CTO of A123 systems, a major lithium ion battery manufacturer, where he led the transition from idea to prototype and through IPO to full scale commercialization. After 11 years at A123, Bart was the Chief Strategy Officer at QuantumScape from 2012 to 2016, developing the strategy to bring solid state lithium ion batteries to viability. After QuantumScape, Bart founded metalenz, a chip-scale lens manufacturing company, and Conamix, a sulfur cathode technology company. Bart now brings his extensive energy market experience to XL Batteries.
