The clean energy revolution, despite recent policy developments, is upon us.

The Netherlands’ main train company now runs entirely on wind energy.

Electric cars are making inroads, especially in high density urban areas.
But, to be frank, batteries are not a great replacement for hydrocarbons: their energy density is relatively low, and recharging times are rather long.

Despite it being irrational for most people, range anxiety is a real thing for some.
This is where solar fuels could provide a solution—a transportable fuel generated using nothing but sunlight.

But production of solar fuels is a tediously inefficient process, since the generation of electricity and production of fuel have to be done separately.

Avoiding that separation is why a new form of solar cell that performs electrolysis (splitting water into hydrogen and oxygen) directly may be the future.
