Adoption, Deals, and Tech
Eos to Supply 480 MWh of Storage in Frontier Power USA’s First Deal
Frontier Power USA, the independent power producer formed this month as a tie-up between zinc battery manufacturer Eos, Cerberus Capital Management, and corporate insurer Ariel Green, has already secured its first deal.
Frontier has agreed to acquire 480 MWh in Texas-based projects from project developer Bimergen Energy Corporation and will deploy Eos Z3 long duration battery systems for the build-out.

Invinity Tapped for World’s Largest VFB
Flexbase, the Swiss project developer created with the purpose of building out an AI data center with energy storage from the world’s largest VFB, has just signed its VFB partner. The firm has tapped UK-based Invinity to provide a 2.1GWh system. Details in Energy Storage News.
EnerSys Brings Predictability to Remote Telecom Networks
As broadband and telecom operators build out edge networks across North America, they face a critical need for long-lasting, durable backup power that keeps operations running in remote areas.
Answering that need, battery manufacturer EnerSys has launched a thin plate pure lead (TPPL) product for improved service life predictability in outdoor and edge communications networks.
The new AlphaCell 4.0HP+ uses an integrated catalyst for internal gas recombination during float operation to reduce float current demand, moderate sensitivity to operating variability, and boost electrochemical stability over the long term.
Amazinc Funded for 1 GWh Within Three Years
Hong Kong-based aqueous zinc startup Amazinc Energy has secured funding to deliver 1 GWh annual capacity within three years.
Spun out of City University of Hong Kong and aimed at the AI data center and UPS markets, Amazinc already operates automated production facilities in mainland China for pilot manufacturing backup power testing.
The funding comes from Hong Kong’s RAISe+ Scheme.

UV-Grafting to Solve Zinc Dendrites and Separator Wettability
GP Energy Tech has announced a recent paper on using UV-grafting to solve zinc dendrite and separator wettability problems.
Per the abstract, the study “presents a surface modification strategy for inherently hydrophobic polyolefin nonwoven substrates via UV-induced grafting of hydrophilic polymers to enhance separator electrochemical performance.”
Read “Tailoring separator wettability and porosity via UV-Grafting to achieve stable nickel-zinc batteries” in Springer Nature Link.
Ground Fault ≠ Thermal Runaway
ZincFive VP Global Sales & Product Brandon Smith breaks down two battery fire hazards – ground fault and thermal runaway – and explains how any battery carries risks of the first, but nickel-zinc batteries are incapable of the second. Watch on LinkedIn.
Octet Case Study: TRL 3 → TRL 5
Dendrite short-circuiting brought one zinc system developer to an R&D standstill. With the help of nearly 30 tested additive candidates, Octet cleared the way — moving the firm from TRL 3 to TRL 5. Read how at the link below.
