REVOLUTIONIZING STATIONARY ENERGY STORAGE COST: Pilot Plant and Go To Market Plan For Zn-ion Rechargeable Batteries

Periodic Reporting for period 2 - ENERZ (REVOLUTIONIZING STATIONARY ENERGY STORAGE COST: Pilot Plant and Go To Market Plan For Zn-ion Rechargeable Batteries)

Reporting period: 2021-11-01 to 2022-10-31

Enerpoly’s unparalleled zinc-ion battery cell technology enables an ultra-low cost, sustainable, and effective solution to balance energy demand and supply in renewable energy projects including solar and wind power. While existing solutions for stationary energy storage can be unsafe, environmentally unfriendly, expensive, and non-suitable for large-scale storage, our unique patent-pending technology is based on the use of zinc and manganese dioxide, abundant materials on the earth that can be totally recyclable at existing alkaline battery recycling plants. Our cells offer 100% rechargeability well after 2,000 cycles with a manufacturing cost at least 50% lower than its Li-ion and Pb-acid counterparts.
Enerpoly is now ready to demonstrate the scalability of its unique patent-pending technology through 1) a proprietary pilot line that will be used to produce testing batches of cells for our clients (battery manufacturers) and 2) testing and customizing our cell technology for several customers that will license our technology and implement it in their manufacturing processes.
The planned technical and commercial tasks have been successfully developed and the corresponding milestones have been achieved.
At the start of the project, the goal was licensing intellectual property rights (IPR) from our portfolio to a third party. After careful consideration and extensive feedback from end-users of the innovation, we have determined that the correct way to commercialize the innovation is to deliver a product to the end-user. This business model is particularly important in considering the protection of intellectual property (IP) and safeguarding the European Union’s goals to provide affordable, secure and sustainable energy for Europe.
During the project, a small pilot line has been designed and installed to demonstrate the manufacturing of the prototype battery. This provides battery manufactures to evaluate ENERZ demonstrator batteries, which at the same time will provide feedback and allow us to refine our product to overcome technical barriers for the construction of formal production lines.
Furthermore, the work to test and validate the battery performance of ENERZ with key European battery manufacturing partners has yet to be initiated. So far, the internal validation has been completed and external validation will occur beyond this project. Testing agreements with battery system integrators includes testing plans for potential customers to test and validate performance for their respective applications. To this date, Enerpoly has signed three agreements with battery system integrators, and are under negotiation with additional potential customers.
Enerpoly performed their first external testing of ENERZ for safety together with Research Institutes of Sweden (RISE). The tests were successful and showed that ENERZ has no possibility to catch fire and allows Enerpoly to fast-track for UL listing in future stationary energy storage systems.
The IPR, risks and management tasks of the project have been effectively implemented and showed good results by the end of the project. One patent was filed and development of the second patent occurred during the project while it is expected to be filed by the end of 2022. The commercialization tasks have been initiated and agreements has been signed with potential customers interested in purchasing the ENERZ product. Public relations, communication and dissemination actions have been deployed with good results and reception from targeted audiences.
Enerpoly’s innovation in battery cells will enable commercialization of cost-efficient rechargeable zinc-ion battery technology for wide adoption in stationary energy storage applications and reduce cost of energy storage (<$100/kWh).
The ENERZ project will contribute to increase the EU’s climate mitigation/adaptation ambition, and to supply clean, affordable, and secure energy. Energy Storage Systems (ESS) are key to accelerate the transition to cost-effective, reliable, and flexible energy, as renewable energy technologies are highly dependent on storage technologies to be able to compete with traditional fossil fuels because of their inherent intermittent nature.
As ENERZ’s zinc-ion batteries penetrate the stationary energy storage market, the lower cost for energy storage systems will enable companies and individuals to increase the adoption of renewables. These systems can now be decentralized and facile the mass-deployment considering the less geographical constraints compared to other large-scale energy storage alternatives such as pumped hydro power. Decentralized renewables (more distributed storage units) also mean more resilience to climate events and less CO2 emissions. It also leads to an increased production and access to energy in remote regions, creating new job opportunities and supporting in reducing the cost of new electric infrastructure and thus poverty.
