For a cleaner and cheaper hydrogen future.
Our Hollow Core alkaline electrolyser stack is built on a novel, patented gas diffusion electrode. By extracting hydrogen without bubbles or a membrane, it combines high efficiency with abundant materials, making green hydrogen affordable.
Until now, cost and scalability have limited the adoption of green hydrogen. Three things are holding back conventional electrolysers.
Bubbles and resistive losses cap conventional stacks at roughly 70 to 80% efficiency, leading to large electricity costs.
PEM electrolysers depend on scarce iridium and Nafion membranes, tying cost and scale-up to fragile supply chains.
Low power density and limited load cycling hold alkaline systems back when paired with fluctuating renewable power.
Pora's Hollow Core membrane-free electrolyser delivers a new way to generate hydrogen while overcoming the challenges facing standard green hydrogen electrolysers.
Fewer components and no membrane cut the cost of the stack and the balance of plant around it.
Removing bubbles from the cell removes the resistive losses that hold conventional stacks back.
Stable operation across a wide load range, matching the swings of wind and solar power.
Cheap electrolysis unlocks decarbonisation in industries where hydrogen is the feedstock.
Fertilizer production is one of the largest hydrogen consumers on Earth.
Direct reduced iron with hydrogen replaces coal in steelmaking.
Refineries, methanol, and hydrogenation processes already run on hydrogen at massive scale, with e-fuels adding demand next.
Gas-breathing electrode concept developed in the Electrochemical Materials and Systems group at Eindhoven University of Technology. Laboratory pilot setup built and patent filed on the core invention.
Over 100 conversations with industrial hydrogen users, developers, and OEMs, alongside the construction of a first pilot system.
Pora Technologies is founded as a TU/e spin-off and brings the Hollow Core Electrolyser to industrial scale.
We are open for discussions with industrial partners, pilot sites, and early investors.
