文摘

Greenhouse gas emission reductions using power-to-x processes are studied using life cycle assessment. Surplus electricity use led to greenhouse gas emission reductions in all studied cases. Highest reductions can be achieved by using hydrogen to replace fossil based hydrogen. High reductions are also achieved when fossil transportation fuels are replaced.
