PO081: Optimized scalable electrolyzer plant concept for wind to H2 production offshore
Irina Tanaeva, VP Hydrogen, Global Key Account Manager, Aker Solutions
Abstract
The expansion of offshore wind is expected to play a key role in the energy transition by providing domestic, clean power at competitive prices. Offshore wind to hydrogen production is an enabler of that expansion, complementing its variable production profile in times of surplus and low e-prices. Various studies have demonstrated the socio-economic benefits of converting electricity to hydrogen in offshore energy hubs where it can be easily transported via pipelines to shore and stored or injected into the onshore hydrogen network. Aker Solutions has developed and optimized a scalable concept for offshore hydrogen production based on the HyLYZER Proton Exchange Membrane (PEM) electrolyzer technology developed by Accelera by Cummins over the last 25 years. Accelera’ s technology has been validated in onshore industrial plants up to 35 MW, while plants of 100 MW are currently under construction. A centralized concept with 160 MW of input power has been identified as the most optimal building block for 2+ GW offshore energy hub developments. The concept is based on decades of Aker Solutions’ experience in offshore platforms safety, design layout, construction and unmanned reliable operation and maintenance. It is a three-floor solution with hydrogen equipment, power electronics and utility systems on the top, middle and bottom floors respectively. The concept has been optimized for size and weight while maximizing hydrogen production through careful electrolyser arrangement, smart operating philosophy, minimized piping and cabling, rational system redundancy and unmanned operation principles. Close collaboration with an offshore wind developer for this work has brought important business case and operational design considerations such as reliability, availability, operations, inspection and maintenance into the system architecture during the critical early stages of development. The resulting concept’s size and cost enable a feasible Levelized Cost Of Hydrogen (LCOH) for demonstration projects such as DEMO2 or SEN1.
