Ready to go? Technology Readiness and Life-cycle Emissions of Electric Road Systems

A discussion paper from the CollERS2 project

The present discussion paper is the result of an international collaboration on ERS research, the CollERS2 project. It summarizes key results of the first workshop with Swedish and German participants held in November 2021. This paper thus has a focus on one of these low-carbon road transport technologies: Electric Road Systems. The main aspects discussed at the CollERS workshop have been the life-cycle greenhouse gas (GHG) emissions of ERS in comparison with other technologies and Technology Readiness Level (TRL) of ERS. The former is key to understand the potential long-term contribution in GHG emission reduction and the latter is important to identify the remaining technical challenges and thus indicating when ERS could contribute.
