POWER-TO-X TECHNOLOGIES

Abstract

Abstract
The transport, buildings and industry sectors, which still rely on gas and liquid fossil fuels, are the sectors
with the highest carbon reduction costs. In this context, Power-to-X technologies, together with the
development of low carbon electricity generation facilities look promising for full decarbonization by 2050.
This paper describes three types of Power-to-X technologies, the basic principle of Power-to-X systems and
the reactions that occur. Then the technical and economic parameters for Power-to-H2, Power-to-CH4 and
Power-to-Liquids are reviewed, followed by their advantages and disadvantages. An assessment is made of
the conditions under which these technologies can compete with the alternative low-carbon production
processes by 2050.
Key words: Power-to-X technologies, Power-to-H2, Power-to-CH4, Power-to-Liquids.
