A geospatial method for estimating the levelised cost of hydrogen production from offshore wind

A method to map the levelised cost of hydrogen from offshore wind farms coupled to onshore electrolysers via HVDC

“…This research uses information on natural conditions such as water depth and wind resources and port facility locations in Ireland according to Ref. [9].…”

“…This is indicative of the typical size of OWF being considered in Irish waters. The foundation technology is selected depending on the water depth of the OWF location [9]. The most widely used layout for OWF is radial cluster topology.…”

“…The distance from the port to the OWF is used to calculate the installation cost and HVDC cable length. The total electricity loss is assumed to be about 14% of annual electricity production (including 10% wake loss [9], and 4% transmission system loss [13]). For this reason, the electrolyser capacity is selected to be 14% less than the OWF capacity.…”

“…The decommissioning cost of an OWF is about 0.37 M€/MW (0.33 M£/MW) [11]. The annual operating and decommissioning costs of the electrolyser are estimated to be about 2% of the 𝐶 𝐸𝐿 [5,9].…”

“…The installation cost is estimated by multiplying the installation vessel's rental rate the total rental time of the vessel, which includes the installation times for the foundation (𝑡 𝑓_𝑖𝑛 ), the turbine (𝑡 𝑤𝑡_𝑖𝑛 ), and the transport (𝑡 𝑡𝑟𝑎𝑛 ). The cost functions of wind farm components were expressed in Ref [9]…”
