Assertion: The Three-Pillars approach will not be necessary once America builds a 100% clean energy grid.

In a future where America's power grid is entirely composed of green energy, the three pillars of green hydrogen production—additionality, time matching, and geographic deliverability—will become unnecessary. Additionality requirements will no longer be relevant because all electricity on the grid will be renewable by default, and there will be no risk of forcing other energy users to rely on fossil fuels. Time matching will be redundant since every moment of grid electricity will be green. Geographic deliverability will lose its significance as the entire grid will uniformly provide renewable energy, making location-based considerations irrelevant.
