With its 100% flexibility, Battolyser® unlocks new ways to significantly reduce your LCOH. It allows production of hydrogen when cheap renewable power is available and to simply turn off production when renewable power is not available. This way it delivers 100% green hydrogen. In addition, its integrated battery functionality unlocks revenues from trading electricity and lowers required investments in off grid renewable projects, resulting in the lowest LCOH.

Battolyser® is intrinsically safe in any operational mode, even at low and rapidly changing loads. Its patented Nickel-Iron technology is inherently robust and has industry leading efficiency and durability. Battolyser Systems can be a major accelerator for the EU to reach its goals on climate, industry, strategic autonomy and economic growth.
We enable greater strategic autonomy and resilience. We build manufacturing capacity of a critical net-zero technologies on European soil, with a European dominant supply chain.

A Battolyser® at its core, is an electrolyser with battery functionality powered by patented Battolyser® technology. With electrodes composed of iron and nickel, we provide a solution that operates 100% flexible and is intrinsically safe and robust. The Battolyser® signifies a breakthrough in technology and is available in modules of 2.5MW, 5MW and 25MW.

Battolyser® 2.5MW Module

The Battolyser® 2.5MW systems is a skid-mounted and fully equipped with Balance of System. Delivery Q1 2025.

Battolyser® 5MW Module

The Battolyser® 5MW is a 5MW/MWh system, skid mounted and can be delivered with a fully equipped Balance of System. Delivery Q2 2025

Battolyser® 25MW Module

Battolyser® 25MW is our large-scale system. It is designed for installations ranging from 10 to 500 MW, generating green hydrogen at scale and at the lowest possible Levelised Cost of Hydrogen. Battolyser 25MW will be in Q3 2026.

Why Battolyser® ?

If you are developing a green hydrogen portfolio, you need a technology that provides the lowest levelized cost of hydrogen, is capable of following any renewable load curve, and is scalable without supply chain constraints. Only a Battolyser® can offer the lowest cost and 100% green hydrogen. Invest in technologies that can meet the scale of the energy transition all the way to net zero. Battolyser® is now available to support achieving this goal.

LOWEST HYDROGEN COST
Battolyser® can achieve the lowest power cost, thanks to its high efficiency and ability to arbitrage between selling power and producing hydrogen.

100% GREEN HYDROGEN
Battolyser® has the unique capacity to produce 100% green hydrogen, instantly following local intermittent renewable energy sources. It is the solution to move towards a net zero energy system.

SCALABLE SUPPLY CHAIN
Battolyser® is a EU compliant electrolyser technology with no dependence on critical raw materials, based on secure supply chains and ‘made in Europe’.

Flexible

By instantly following the intermittent nature of renewable energies, the Battolyser® ensures the production of 100% green hydrogen and enables the lowest cost green hydrogen in comparison to conventional electrolysers. It’s the world’s only commercially available electrolyser 
with battery capacity and produces green hydrogen only when electricity prices are low enough and can sell electricity back to the grid when prices are high to generate additional revenues..

Safe & robust

Intrinsically safe and robust in any operational mode (charge, discharge, idle) without causing any system degradation. The electrodes have a regenerative catalyst that ensures robust and long-lasting electrolysis. Battolyser® electrodes are proven in nickel-iron batteries that have been in operation for over 40 years and the stacks can be easily recycled at end of life.

Versatile

Battolyser Systems’ technology is a platform technology that due to its flexibility and battery capacity can enable lowest cost green hydrogen for a wide array of applications and use cases. Typically, Battolyser Systems can deliver solutions that add value in on and off-grid applications as well as in flexible and base load hydrogen offtake applications.

Techno-economic model

We have developed a techno-economic model of a Battolyser System installation.

Given assumptions on product specifications and multiple energy markets, our model simulates optimal operation of the Battolyser® and competitive products. We use it to show the value of the Battolyser® to customers. It also helps us to challenge and substantiate our strategic and product development decisions.

Our algorithm enables us to simultaneously optimise bids for any combination of energy markets (off-grid, day-ahead, intraday, imbalance, grid services, arbitrage) and different renewable energy sources (off- and onshore wind, solar, PPA) in compliance with recent regulations.
