Wärtsilä study examines the potential of Power-to-X fuels for power generation

Wärtsilä’s comprehensive new whitepaper explores the potential of Power-to-X fuels for enabling a decarbonised future.

Posted on June 21, 2023

A newly published whitepaper by technology group Wärtsilä provides an in-depth study on the potential of Power-to-X (P2X) fuels in enabling a decarbonised future for the global energy sector. Entitled “The feasibility of Power-to-X fuels for power generation”, the study examines the entire value chain of P2X fuels, analyses cost predictions, and provides detailed analysis of P2X fuels in energy systems via Wärtsilä’s extensive modelling capabilities. The new and comprehensive analysis brings clarity to the economic feasibility of P2X fuels.

P2X technologies convert electricity into carbon-neutral synthetic fuels. Combined with balancing power generation such as engines or energy storage, this process is widely viewed as being a viable means to achieve sustainable power production. The main P2X fuel options for power generation in the study are green hydrogen, synthetic methane, ammonia and methanol.

“For power systems to be fully decarbonised we need to go beyond the solutions that are widely utilised today,” says Business Development Manager Tuomas Paloviita from Wärtsilä. “We need technologies that provide greater operational flexibility and facilitate the seamless integration of renewable energy. We believe that P2X fuels will be essential for meeting both the seasonal and shorter-term balancing requirements of the grid.”

Wärtsilä has invested heavily in the development of engines capable of operating with sustainable fuels, including P2X fuels. The company has outstanding testing facilities and capabilities, as well as years of in-house experience. Wärtsilä’s Sustainable Technology Hub features a dedicated fuel laboratory where testing and engine compatibility assessments can be carried out under one roof.

Wärtsilä has considerable expertise in power system modelling. Wärtsilä’s in-house modelling team utilise PLEXOS, a third-party techno-economic simulation software, allowing Wärtsilä to assess the feasibility of utilising P2X and energy storage under actual operating conditions. Wärtsilä supports its partners with project level analysis using PLEXOS and Excel tools. The study provides a comprehensive feasibility analysis on the cost of using sustainable fuels for reliable power generation and long-term storage in the future.

The whitepaper can be read on Wärtsilä’s website:
