Could this new development make renewable hydrogen cheaper?

In 10 seconds? Scientists have developed a new kind of solar panel that has achieved 9% efficiency in converting water into hydrogen and oxygen. This development is a major leap in technology as it is nearly 10 times more efficient than other solar-water splitting experiments to date!

Ok, but what exactly does this mean? Scientists have long been trying to mimic a crucial step in photosynthesis that converts water into hydrogen and oxygen. This new development has achieved just that at a rate that is parallel to that achieved by plants in a natural environment. Why is this important? Well, artificial photosynthesis can help us on the road to carbon neutrality by enabling us to produce hydrogen for fuel without the carbon emissions that are currently produced by obtaining hydrogen from fossil fuels.
