Austrian Institute of Technology Unveils PH2OeNIX Project for Off-Grid Photovoltaic and Electrolyzer Integration.

Philipp Mayer-Ullmann from the Austrian Institute of Technology discusses the PH2OeNIX project, which focuses on directly coupling photovoltaics (PV) with electrolyzers in an off-grid setting. The motivation behind this research includes technological advancements for renewable energy expansion and policy alignment with Austria's Mission 2030 climate strategy. As a key player in sector coupling, AIT has developed a demonstrator unit at their Seibersdorf campus to explore hydrogen value chain integration using PV technology. Three methods are considered: grid-coupled, on-site AC-connected systems like PH2OeNIX, and direct DC coupling without conversion losses. At Seibersdorf, they installed a 400-kilowatt peak PV system dedicating part of it to electrolysis via two types of electrolyzers within a containerized setup that also features gas storage and fuel cells for electricity reconversion during low solar periods. Research aims include analyzing weather impacts on generation efficiency and developing models for urban applications where rooftop solar is feasible but wind turbines aren't practical—focusing primarily on long-term hydrogen storage solutions derived from surplus PV power.
