1、siemens- crucial business on the way to a carbon-free worldWe are happy to share some of our ideas and perspectives through this technical white paper.Power-to-X is a key enabler for the energy transition.Why?Leveraging the potential from hydrogen in Power-to-X means,electricity is converted-prefera

2、bly from renewable energy sources-to hydrogen or to hydrogen-based synthet-ic fuels and feedstock(like methane,methanol or ammo-nia).These can be stored,transported and used in all kinds of energy consuming sectors.This is especially interesting for sectors where decarboniza-tion via electrification

4、er for sector coupling.Additionally,in the longer-term,hydrogen is a viable option to store excess electricity from wind or solar over longer periods and in huge amounts.Alternatively,it can be fed into(already existing)natural gas infrastructures.Demand for hydrogen will potentially further increas

5、e.Sector coupling and further progress in fuel-cell technolo-gies will foster the development of low-emission hydrogen technologies and allow to unlock economic and technologic value to the entire energy system.I strongly believe that the next step of the global energy transition will be based on th
