Two of SINTEF Energy's sommerforskere (summer scientists) this year are working for the ZeroKyst project. Marie Sølvik and Anette Guddal Øvreeide have both recently completed bachelors' degrees in renewable energy. They will start working on their masters' this autumn, but before that, they will work for ZeroKyst.
Both students will look at fishing vessels' energy needs. If the project is to achieve zero-emission propulsion, it needs to know about fishermen's use patterns, and how much energy they need on the boat to do their jobs. Marie Sølvik will also look at how the boats will be charged – how often, how fast, and where on the vessel the charging equipment should be located.
– The project is even more exciting than I expected, says Marie. It's also important. A lot of transportation on land is already electrified, but we need to achieve this at sea as well.
She adds that finding out how much energy a fishing vessel needs on a "typical day" is challenging because it can vary greatly, depending on factors like the weather, where the fish is located, and which wholesaler offers the best price.
Anette Guddal Øvreeide will look at the hydrogen aspect.
– My focus is on the barges that will be used as bunkering stations. How much hydrogen should we store on them? Where should they be located?
She explains that how much hydrogen should be stored on the barges is not just a function of energy needs, but also of available space and technical requirements, since hydrogen needs to be stored at a high pressure.
The students are doing their work under the guidance of SINTEF Energy scientists Eirill Bachmann Mehammer and Ingrid Snustad.
