The delivery of the 10 5MW alkaline electrolyser stacks netted the Swedish firm €14.9m ($17.3m).
It comes as part of two orders for the hydrogen production technology placed by Motor Oil: one for 30MW and one for 20MW.
Once fully installed, the 50MW plant will produce green hydrogen to replace partial volumes of grey hydrogen already used in the Corinth refinery, as well as supplying a recently opened refuelling station.
The hydrogen production plant is being supported by €111.7m ($129.7m) in EU funding.
The electrolysis system is based on pressurised alkaline technology licensed from China’s Peric, and is assembled at Metacon’s factory in Patras, Greece.
Metacon said work on the manufacturing and delivery of the remaining 30MW is continuing “according to plan.”
The delivery comes after the company reported SEK 56.7m ($5.38m) in net sales for Q2 2025, which it said was primarily driven by the Motor Oil project.
