Description

The study conducted by EMEC and AREVA H2Gen is exploring the feasibility of adding a sea water reverse osmosis unit to the Eday hydrogen system. The aim is to replicate the system in areas with water scarcity. The report outlines factors affecting reverse osmosis systems, technical challenges, and associated costs. The study concludes that utilising the current water supply on Eday or a newly drilled local borehole is a more viable solution for the electrolyser system, emphasizing cost-effectiveness and practicality over the challenging implementation of a sea water reverse osmosis system.
