Large scale, integrated hydrogen plants represent the next logical step in water electrolysis to decarbonize large industries currently dependent on fossil based hydrogen. Electric Hydrogen will present their solution that reduces the total installed cost based on the worlds most advanced PEM water electrolysis. By integrating controls and standardizing the balance of plant, Electric Hydrogen has taken on scope that is bespoke in other systems. In this presentation, I will discuss specific design choices that lower the initial cap-ex and operating expense which ultimately lead to the lowest levelized cost of hydrogen.
