Abstract
The energy transition towards renewable energy is one of the main challenges towards a greener planet. However, due to the intermittency of renewable energy, part of the energy production needs to be stored for later use. One of the inventions that can be used is the Ocean Battery, a hydro pumped storage system designed by Ocean Grazer B.V. The Ocean Battery is mainly used for short term storage; a hydrogen production with a subsequent conversion to methane or methanol has the potential to add over-seasonal storage. However, the interactions between the Ocean Battery and a hydrogen production have not yet been assessed. This thesis aims to show the added value of the Ocean Battery on the energy efficiency of an offshore hydrogen production. Next to this, it aims to show the energy efficiency of the transportation to shore of the produced energy. To achieve this, a simulation model was made in Simulink using technical input data found in literature. The simulation model allowed to analyse and compare different scenarios. The results showed that the Ocean Battery has a short term influence on the hydrogen output of the electrolyzers. It was also established that in the current methane and methanol production and transportation through pipelines, CO2 capture from air is by far the most energy consuming.
