ANNOUNCES MAJOR VANADIUM FLOW BATTERY CONTRACT
Pu Neng Energy has been awarded a contract for construction of a 12-megawatt-hour vanadium flow battery as phase 1 of a larger 40-megawatt-hour energy storage project in Hubei province, China.
This is a major milestone for Pu Neng and represents significant value to Sparton Resources Inc. (SRI.V) Sparton's 89.8-per-cent-owned subsidiary, VanSpar Mining Inc. holds a minority interest in Pu Neng.
"We are delighted with Pu Neng's progress this year," stated Lee Barker, Sparton's chief executive officer. "All of the staff are to be commended on achieving this milestone in Pu Neng's development as the vanadium redox battery (VRB) manufacturer of choice for the energy storage industry."

Pu Neng wins contract for the largest vanadium flow battery in China as the China National Development and Reform Commission initiates a major push for energy storage in support of renewable energy
Vanadium redox (flow) battery (VRB) systems are poised to transform the largest utility grid in the world with low-cost, long-life performance in support of significant growth in solar and wind energy.
Pu Neng, the leading provider of vanadium flow battery technology in the world, has been awarded a contract for a three-megawatt 12-megawatt-hour VRB as phase 1 of the Hubei Zaoyang 10-megawatt 40megawatt-hour storage integration demonstration project. This first phase will be installed in Zaoyang, Hubei, to integrate a large solar photovoltaic system into the grid. Following this 10-megawatt 40megawatt-hour project, there will be a larger 100-megawatt 500-megawatt-hour energy storage project that will be the cornerstone of a new smart energy grid in Hubei province. This large project will serve as a critical peak power plant, delivering reliability and emissions reductions.
This type of project is a glimpse of the future of the Chinese electricity grid as the country is halting construction of many coal-fired power plants and pushing the integration of renewable energy with energy storage. On Sept. 22, 2017, the China National Development and Reform Commission (NDRC) released Document 1701, "Guidance on the Promotion of Energy Storage Technology and Industry Development," aimed at accelerating the deployment of energy storage. The policy calls for the launch of pilot projects, including deployment of multiple 100-megawatt-scale vanadium flow batteries, by the end of 2020, with the aim of large-scale deployment over the ensuing five years.
Pu Neng signed the Hubei Zaoyang project contract with Hubei Pingfan Vanadium Energy Storage Technology Company on Oct. 18, 2017, at a signing ceremony attended by Zaoyang City Deputy Mayor Chen Dong. Pu Neng's president, Dr. Huang Mianyan, commented: "We are delighted to work with Hubei Pingfan for the development of this leading-edge project, which is a demonstration of their leadership in this sector." Pingfan Xie Guangguo, chairman of Hubei Pingfan, said: "We selected a vanadium flow battery because they have superior safety, reliability and life cycle economics compared to lithium-ion and other battery types. We selected Pu Neng because it is the leader in China with its VRB technology and has a track record of performance with State Grid Corp. of China."
The project will be located in Zaoyang, and installation of the VRB system will commence in November, 2017. When phase 1 is completed in early 2018, Pu Neng's VRB will be the largest flow battery installed in China. As part of the initial agreement, Pu Neng and Hubei Vanadium will jointly develop a vanadium electrolyte supply from local vanadium sources, helping revitalize the local industrial base to meet future demand for energy storage.
Robert Friedland, chairman of Pu Neng, commented: "China has the largest and highest-grade vanadium resources in the world and is poised to use this miracle metal to fundamentally transform its electricity grid. With massive amounts of renewable energy and storage coming on line, China will create the most modern, clean and efficient grid in the world."
Regarding this initial contract in Hubei, he added: "Earlier this year, Chairman Xie and I discussed the opportunity to utilize Hubei's abundant vanadium resources and Pu Neng's next-generation technology to set a new benchmark for the global energy storage industry. This is just the first step of what will be many projects working together."
On the newly released NDRC policy, he commented, "This new policy will result in vanadium flow batteries revolutionizing modern electricity grids in the way that lithium-ion batteries are enabling the global transition to electric vehicles."
Flow batteries store energy in liquid electrolyte, which is held in tanks external to the cell stacks that contain the cathode (positive) and anode (negative) sides of the battery. When charging or discharging the battery, electrons are added into or drawn out of the electrolyte as it circulates across membranes inside the stacks. Unlike other types of batteries, vanadium flow batteries use the same electrolyte solution on both the positive and negative side of the battery, yielding a nearly infinitely repeatable electrochemical process.
While lithium-based batteries are well suited to consumer electronics and electric vehicles, their lifetimes can be limited. Pu Neng's VRB technology can be fully drained over an almost unlimited number of charge and discharge cycles without wearing out. This is an important factor when matching the daily demands of utility-scale solar and wind power generation.
