The technical know-how of John Cockerill in the field of alkaline electrolysers is based on decades of experience and more than 1,000 references. However, this mature technology still has room for improvement. Our ambitious R&D program aims to concretise this tremendous potential with the will to maintain and reinforce John Cockerill’s technical leadership of this technology.
For alkaline electrolysers, the R&D goals are mainly focused on decreasing the capital and operational expenses (CAPEX & OPEX) associated with John Cockerill installations. Key research fields are:
  • increasing the maximum unitary power of our biggest electrolyser from 5 MW per electrolyser, to 10 and 20 MW in the coming years
  • increasing the electrolyser operating pressure 
  • decreasing the electrolyser electrical specific consumption (kWh / Nm³)  

In addition to those R&D topics, John Cockerill is also completing its product range by working on its products certification (among others CE and ASME), and containerised solutions as well as solutions for the mobility market.

In the continuity of its historical activity in hydrogen, John Cockerill is always willing to provide solutions to meet the needs of its time and needs of its customers and wants to stay at the forefront of electrolysis technology. We are constantly creating partnerships with universities, research centres and industrial partners dedicated to alternative technologies for alkaline water electrolysis.



Colombus is an innovative Carbon Capture and Utilisation (“CCU”) project in Wallonia.

In partnership with Carmeuse and ENGIE, this project – the largest of its kind in the world – will concentrate CO2 from an innovative type of lime kiln, combine it with green hydrogen – 75 MW plant – and produce “e-methane”, a renewable gas that can be injected into the gas grid, used in transport or in industry. With this project, John Cockerill and its partners are opening new routes for significant carbon emission reductions in Europe and across the world.

Our ambitious R&D program aims to concretise this tremendous potential with the will to maintain and reinforce John Cockerill’s technical leadership of this technology.
