When EEnotech was founded as a Startup foundry in 2017, the founders had only one aim in mind—spinning out many new exciting technology Startups in the space of energy and environment to support the sustainability of the world. Since then, the company has licensed multiple innovative technologies developed in Professor Yi Cui’s—the co-founder of EEnotech—lab at Stanford University. They have provided financial and infrastructure resources, built up the team to develop these innovations into scalable commercial prototypes. “We are spinning out four Startups during phase 1 in four exciting areas: Energy storage, water filtration, thermal textile, and building materials. In phase 2, we will license many game-changing technologies broadly from Stanford University and other institutions in the area of energy and environment,” says Meng Sui, the CEO, and co-founder of EEnotech.
As the first spinout of EEnotech, EnerVenue makes an extensive effort to meet the high demands for stationary energy storage. “Our energy storage product is cost-effective with long cycle and calendar life as well as eco-friendly and safe for the environment,” says Meng. On top of these characteristics, EnerVenue’s product has a fast-charging capability within six minutes and can also operate in wide ranges of temperature from -40°C up to +60°C. “We truly believe that our storage product can be infused with solar energy storage, wind farms, home storage, commercial building, as well as a variety of other storage applications,” mentions Meng.
At its core, EnerVenue's product is based on nickel-hydrogen (Ni-H2) gas batteries. In this battery chemistry, the cathode is NiOOH and Ni(OH)2 during charge and discharge, respectively. This Ni cathode chemistry, which could run up to 100,000 cycles, is probably one of the longest lifetime cathode chemistries ever invented throughout human history. On the other side, the anode chemistry is H2 gas transforming into water reversibly using a catalyst.
This hydrogen anode chemistry might be one of the longest life anode chemistries ever invented. “At EnerVenue, we combine the longest life cathode and the longest life anode to produce nickel-hydrogen gas batteries.
We have seen the cycle life of this chemistry can be as long as 30,000 cycles,” states Professor Yi Cui. Additionally, the calendar life can go up for 30 years, and the energy storage cost per kilowatt-hour per cycle can get down to as low as one penny.
The Ni-H2chemistry is based on the aqueous solution and the hermetically-sealed canister, making it very safe against overcharge and in abused environment settings. It can be fast-charged within minutes. The performance of the Ni-H2 chemistry was also proven in the past by 40 years of research and application in the aerospace industry. However, the cost of batteries was too high due to the high cost of several components inside. Now EnerVenue has developed ways to reduce the cost by hundreds of times.
Speaking of applications, EnerVenue’s Ni-H2 batteries can be used for storing solar cell electricity and wind farm electricity, and also for individual homes storing electricity. For example, after midnight until 6 AM, a home can store low-cost electricity up to six hours then use the stored electricity when needed outside those time frames. This method is eco-friendly as well as reduces a significant amount of cost for each individual’s home. These types of Ni-H2 batteries could be used for commercial building too. The battery chemistry is also suitable for the use in electric grid companies to do peak shaving and stabilizing the frequency.
By delivering energy storage solutions for stationary use, EnerVenue is currently not only offering cost and performance efficiency but also helping to fight climate change. “We are raising funding to build our pilot-scale manufacturing facility. Given the maturity of this technology, we will expand fast to a large scale manufacturing company. We plan to expand into Silicon Valley by 2021,” concludes Meng.
