Frequently Asked Questions
Our Roots and Mission
Redox One is a proud spin-off of Tharisa plc, headquartered in Cyprus, with dedicated labs and engineering offices in Germany. Our mission is clear: to accelerate the clean energy transition by delivering safe, sustainable, and cost-effective energy storage solutions to industries, communities, and nations around the world. We are passionate about reshaping the future of energy with our proprietary Iron-Chromium Redox Flow Battery technology.
As the world grows capacity of wind and solar to over 1000 GW by 2030, there’ll be a need for Long Duration Energy Storage to grow from today’s installed capacity of less than 200 GWh to over 5000 GWh. As the world increasingly adopts renewable energy sources (ie solar and wind), the widespread adoption of Long Duration Energy Storage (LDES) from 4 to 12 hours is key to manage intermittencies and the temporal differences in peak supply and demand.
The world will need up to 140 terawatt-hours (TWh) of Long Duration Energy Storage (LDES) by 2040 to meet net-zero emissions goals and enable a fully decarbonized power system. This figure has been reported in several major studies, including those by the LDES Council in collaboration with McKinsey & Company.
Safe, sustainable, and cost-effective, Redox One’s Iron-Chromium Redox Flow Batteries are poised to power a decarbonised future in a market growing to $3 trillion by 2040.
Redox One – Switched On. Always.
Why Redox One Matters
The global transition to clean energy hinges not just on generating more renewables — but on making them available when and where they’re needed. At Redox One, we solve the critical bottleneck of reliable, scalable, and sustainable Long Duration Energy Storage (LDES) — without relying on scarce minerals, unsafe chemistries, or fragile global supply chains.
Our Iron-Chromium Redox Flow Batteries are engineered to deliver intra-day energy storage at utility scale, with unmatched safety, longevity, and economic efficiency. Unlike conventional battery systems, our technology decouples power and energy, enabling flexible deployments from behind-the-meter solutions to grid-scale infrastructure.
Redox One matters because we’re not just building batteries — we’re enabling a grid that works when the sun isn’t shining, the wind isn’t blowing, and demand is peaking. We provide the missing piece to a 100% renewable future — one that’s safe, sustainable, cost-effective, and built to last for decades.
Strong Partnerships
We do not walk this path alone. Redox One has secured partnerships with key players like our majority shareholder, Tharisa plc, ensuring multi-generational access to Iron-Chromium. We collaborate with industry giants Chariot Transitional Energy, who serve as our system integration partners.
From Ground to Gigawatt-hour
Our unique partnerships allow us to manage the entire process, from mine to megawatt and ground to gigawatt-hour. We’re not just delivering safe batteries; we’re powering progress and fostering a sustainable, resilient, and abundant world of clean energy, for a switched on tomorrow.
