As the world pushes forward with incentives for green hydrogen and related derivatives, we see typical concept-design-build timelines shrinking. At the same time, electrolysis is a developing technology embedded in a plant which relies on wind & solar inputs that vary by the minute, the day, and the season - unlike any other power plant or chemical process. The costs of power generation, power storage, and hydrogen storage are all complex variables in this equation of capex, opex, and ultimately LCOH.

In this case study, we review highlights of a recent feasibility study for a Green Hydrogen Project in Canada in which we considered the wind and solar variability, the amount of wind and solar power generated, storage size, battery size, electrolyzer overbuild, etc in our journey with the client to develop an end-to-end conceptual design which optimizes the LCOH while ensuring operability and constructability.
