A Chinese firm is to use a 2 MW energy storage system developed in the US. China’s Ray Power Systems will use Massachusetts firm A123 Systems’ storage solution in a project to regulate grid frequency.

Ray Power said it will assess whether the storage system can help overcome “ramp-management” challenges and integrate renewable power sources into the grid.

Eldon Mou, CEO of Ray Power, said: “The project in China will be designed to validate the technical capabilities and benefits of energy storage as a fast-ramping, accurate and clean resource for providing frequency regulation services.”

Robert Johnson, vice president of the Energy Solutions Group at A123, said: “We believe that China represents a large market opportunity for our energy storage technology, including as a solution to address the ramp-management challenges associated with the increased deployment of wind and other renewable energy generation assets.”

A123’s nanophosphate system includes the use of lithium iron phosphate batteries. 

The company said: “Our proprietary Nanophosphate lithium iron phosphate technology is built on novel nanoscale materials initially developed at the Massachusetts Institute of Technology and is designed to deliver high power and energy density, increased safety and extended life.”

Mou added: “A123 Systems has demonstrated the viability and reliability of its product through a number of successful global commercial deployments, and we expect this project to showcase energy storage as a valuable resource for meeting China's growing frequency regulation demand.”
