hela Sverige Sustainability including climate change are the challenges of our generation. Our contribution is to offer leading transport and infrastructure solutions enabling societies to prosper in a sustainable way.
Powertrain Strategic Development at Volvo has the responsibility to explore and develop new sustainable propulsion solutions, including hydrogen-based propulsion technologies. We are focused on developing the vehicle itself, but also in ensuring that the infrastructure can support a commercially viable rollout of hydrogen vehicles. This thesis work will support us in establishing the relationship between the hydrogen fuelled vehicles and the refueling infrastructure.
Thesis Background
At Volvo, we are committed to the ambitions and climate change goals of the Paris Agreement. From a lifecycle perspective, most of the emissions occur during the use phase of our products. Therefore, our priority is to develop solutions that reduce the carbon emissions from transportation. One such transport solution that we are working on today is Fuel Cell Electric Vehicle (FCEV) for demanding long-haul applications, that is to complement the Battery Electric Vehicles (BEV), which have a limited range.
Among its benefits are the low weight of hydrogen and ability to have a quick refuel. But this ability to refuel depends on the location, type, capability and queues at hydrogen refueling stations. Hydrogen refueling stations are also very expensive. So it is important to right-size the infrastructure solution so that it provides maximum benefits at minimum cost.
Problem motivating the project
Hydrogen refueling stations can be very expensive. There is also a possibility that several trucks arriving at a refueling station can cause long queue that could stretch into several hours. We want to understand how extensive such queues would be based on different market penetration of hydrogen fueled trucks and also how such queues can be mitigated in a cost effective manner.
The analysis method will include developing a model of a road network where the traffic density of hydrogen trucks is varied. The road network will also have several hydrogen refueling stations with varying capacity and cost. The simulation model will be used to analyze the build up of queues at different refueling stations based on certain parameters that the truck use to decide where to refuel.
In the next step, we plan to introduce several mathematical models to understand how the cost of hydrogen infrastructure as well as queue times can be reduced. This will involve the use of optimization algorithms as well as potential use of machine learning or other mathematical techniques. We will also investigate the impact of traffic, price difference in hydrogen at different stations, refueling decision making process of the drivers and other factors.
This master thesis student will also interact with other projects at Volvo that focus on driver productivity tools such as navigation, route planning and mission management.
