A generic term for technologies that convert renewable electricity into another form of energy, such as fuels and, where appropriate, back into electricity. The essential raw material is green, i.e. hydrogen produced with renewable electricity. 

The challenge of renewable electricity production is its variability.  Power-to-x enables, among other things, the storage of renewable electricity as hydrogen or further refined synthetic fuel.

• Hydrogen is produced by electrolysis from water using wind or solar energy  
• Hydrogen can be utilized at a later date, further refined or converted back into electricity 

Projects underway

Finland’s first industrial-scale green hydrogen production plant is about to be built in Harjavalta. 

• The P2X Solutions plant is estimated to reduce Finland’s carbon dioxide emissions by 40,000 tonnes annually 
• The oxygen and heat generated as by-products in the production process are utilized in other industries in the area 
• The plant is expected to start production year 2024

Sweco has also been selected to design dozens of other power-to-x projects at different stages. 

Aim for the world

Power-to-x and hydrogen will play an important role in the green transition. It will enable Finland to reach its ambitious emission targets, but the possibilities are even wider: 

 A well-functioning hydrogen economy and solutions can be both a know-how and product-based export asset for Finland. As always, there may be bumps along the way, but in the long term I am convinced that hydrogen will play a key role in managing climate change. There is demand for solutions around the world.
