Rongke Power, technically invested by Dalian Institute of Chemical Physics, was elected to the China-US Eco-Partnership, a platform established based on the Ten Year Energy and Environment Cooperation Framework. Rongke Power and UniEnergy Technologies (UET) signed the letter of Intent for cooperation under the program of China-US Eco-Partnership on June 6th 2016 in Beijing.

According to the letter of Intent for cooperation, Rongke Power and UET will co-develop the vanadium flow batteries, upgrade the key technologies, optimize energy storage solutions and establish economic models for both China and U.S. markets. In addition, the effective mutual collaborations are expected to further promote renewable applications and enhance the clean, efficient and safe electricity network.

"The collaborations between Chinese and American enterprises will help partners of both sides to better face the challenges from climate changes and to promote renewable energy applications," said John Forbes Kerry, American Secretary of State. He also highlighted that the technology of energy storage will bring fundamental changes to future electricity grids and energy supply system.

Large-scale flow battery energy storage systems generally consist of hundreds of stacks and dozens of energy storage inverters. Integration and control technology for energy storage systems directly affect the reliability and stability of flow batteries. Therefore, DICP proposed a modular technological route and developed the flow battery modules with different power rates. Moreover, DICP has successfully developed the operational monitoring, predictive diagnostics, and a self-repairing control system. They have also created a multisystem coupling control technology to improve system safety and reliability under operating conditions.

In recent years, DICP together with Rongke Power, have actively pursued demonstrations in different fields. More than 10 energy storage demonstration projects have been implemented for island and other remote areas; distributed power supply and smooth output of wind farms and planed generation. The world’s largest 5 MW/10 MWh VFB storage system developed by DALIAN RONGKE POWER CO. Ltd and technologically supported by the DICP Energy Storage Division, successfully integrated to the grid in March 2013.

China State Councilor, YANG Jiechi stated the eco-partnership between China and U.S. has made remarkable achievements since the establishment seven years ago. China government will consistently push forward the sustainable growth and take active measures to tackle the problems of climate changes.
