Resilience in electricity & charging systems – challenges and opportunities with marine public transport

“Resultaten visar på stor potential och jag ser fram emot fortsatt samarbeten i Karlskrona med verklig provning, simulering och optimering. Tillsammans med BTH, Affärsverken och Karlskrona har vi stora möjligheter att göra något som blir bra!” Tobias Husberg, projektledare & grundare, CSTRIDER.

SLUTRAPPORT

The transport sector accounts for a significant share of the world’s greenhouse gas emissions, and the project’s goal is to reduce these by improving resilience, energy efficiency and environmental impact, and optimizing a marine transport system. Waterborne public transport has great potential to reduce congestion and increase capacity in cities, especially by utilizing waterways in combination with road and rail transport networks.The project has investigated different solutions for a marine transport system, with a particular focus on energy efficiency, charging, energy storage and infrastructure. A central goal has been to develop a model to optimize a system that can withstand disruptions in energy supply. Through simulations, the system’s dimensioning, battery storage and use of fuel cells have been evaluated to improve both resilience and operational reliability.The results show that it is possible to develop a more resilient and flexible transport system by combining electrification, land-based battery storage and fuel cells on board ships. This system has the potential to reduce climate impact, improve accessibility and increase transport efficiency, especially in cities. The simulations indicate that the system can reduce both energy and time consumption in urban traffic. To further develop the system, future tests and optimization using AI for real-time operation are planned, as well as tests of the system in Karlskrona. In addition, the possibility of implementing a dual-use use of the system is being investigated, which would make it possible to use the ferries for other purposes, such as evacuating civilians and animals or transporting supplies and injured people.

“- BTH:s simuleringar indikerar att Cstriders virtuella brolösning mellan handelshamnen och NKT kan spara upp till 20 minuter i restid per dag och minska energiåtgången för resan med cirka 95 procent. Elektrifieringslösningen är dessutom kostnadseffektiv och kräver inga stora infrastrukturinvesteringar, säger Cstriders grundare Dr Tobias Husberg”

About

The project will investigate possible electrical systems for a transport system with passenger ferries in urban public transport. Investigate how a marine transport system can be integrated with energy storage and the power grid, and at the same time be flexible to withstand disturbances. This includes energy efficiency, resilience, charging and land infrastructure. The goal is to increase knowledge about system limitations, requirements for the transport system and the electricity infrastructure in order to maintain transport capacity in the event of disturbances. As well as requirements for flexibility in the transport system to function under different infrastructure conditions.
