Theoretical energy by water split technology
Webb16 maj 2024 · The actual splitting itself is usually powered by an electric current or solar power, but because water only captures a small portion of the light spectrum, it's more productive to convert sunshine into energy … WebbTheoretical modelling shows that two-photon water splitting can be used to achieve a maximum solar-to-hydrogen efficiency of 18.8%, which could be increased further to 28.6% through photochemical instead of thermal H 2 release. It is therefore possible to exceed the maximum efficiency of dual absorber systems while only requiring a single catalyst.
