Systems and methods are described for powering a load, such as a data center, with renewable energy from a renewable energy source. When the renewable energy is greater than a demand of the load, excess renewable energy is used to power a hydrogen production device or charge a battery depending on whether or not the charge level of the battery satisfies an upper threshold charge level, respectively. When the renewable energy is less than the demand of the load and the charge level of the battery satisfies a lower threshold charge level, the load is powered with energy from the battery. When the renewable energy is less than the demand of the load and the charge level of the battery does not satisfy the lower threshold charge level, the load is powered and the battery is charged with energy generated by the hydrogen-based energy generator.
