CONVERGE Solving the energy distribution in road construction

Purpose and goal:

Förstudien CONVERGE gathers the lessons learned in previous and ongoing electrification projects with the ambition to lead to a large demonstration project that handles identified challenges for larger infrastructure projects. The overall goal was to create a system solution for the use and transfer of electrical energy to a fleet of machines. The constellation in the project has progressed, based on the results of this project, to a full-scale proposal within FFI Nollemission.

Expected results and effects:

The project mapped the conditions at demo sites, further developed decision support for system dimensioning, studied the consequences on the electricity grid and electricity infrastructure. Both the Electrified Infrastructure project and CONVERGE point to the advantages of a system solution for the use and transfer of electrical energy to a fleet of machines with an exchange system for batteries.

The projects also showed the potential to reduce the total amount of batteries in the system, with cost and environmental benefits as results, as well as system benefits in weak power grids. Approach and implementation:

The project was run with frequent project meetings with work divided into different milestones / work packages. Site visits have been made by both academic and industrial parties. One of the lessons learned is that an underestimation of the time required to obtain material from network owners, etc. An important lesson going forward as it needs to be easier in the future for contractors at e.g. procurements.
