TETRA Technologies, Inc.and Eos Energy Enterprises, Inc., a leading provider of safe, scalable, efficient and sustainable zinc-based long duration energy storage systems, announced that they have signed a strategic term sheet regarding a long-term supply and collaboration agreement to support the manufacturing of Eos’ innovative Znyth® aqueous zinc battery. Key to the operational success of the Zynth system is high purity zinc-bromide, which is part of Eos’ patented electrolyte system. TETRA’s U.S. based patented manufacturing process produces some of the highest purity levels of zinc-bromide (PureFlow™) globally. TETRA and Eos will collaborate for improved battery performance, cost and system life including an end-of-life solution using TETRA’s extensive experience with reclaiming and recycling zinc bromide.
As reported during its third quarter 2021 earnings call, Eos had a backlog in excess of $150 million at the end of September 2021 with an opportunity pipeline of $3.7 billion representing 22 GWh. Eos is projected to expand manufacturing capacity to 800 MWh in 2022. Aligning Eos and TETRA’s resources is expected to optimize sourcing and support the growing stationary storage market. TETRA’s source of bromine and manufacturing operations are based in Arkansas, further strengthening Eos’ domestic supply chain and supporting current U.S. initiatives for domestic manufacturing of clean energy solutions. Additionally, TETRA’s recently reported bromine exploration target of between 2.5 million and 8.6 million tons in the Smackover Formation in Arkansas, provides Eos with assurance of having access to the key minerals required to expand.
Eos Chief Executive Officer Joe Mastrangelo commented, “We are pleased to partner with a U.S. based supplier like TETRA that will enable our supply chain continuity and provide access to untapped reserves of bromine as our Company grows. Further, they allow us to continue to produce a product that is recyclable at the end of life and accelerates the shift to clean energy.”
Brady Murphy, TETRA’s Chief Executive Officer, stated, “We are very pleased to partner with Eos and support cost effective, safe, long duration energy storage technology such as the Eos Znyth® aqueous zinc battery. This relationship aligns well with our strategy to utilize our aqueous chemistry core competency to enable the supply chain for low carbon energy solutions.”
