Solar, wind, and biomass energy are among the alternative power sources used to produce this type of clean hydrogen. The term yellow hydrogen applies specifically to production via solar power.

while the remaining 10% are categorised as “blue” hydrogen, involving fossil-based production methods with carbon capture utilisation and storage (CCUS), and “yellow” hydrogen uses waste as feedstock.

The whole ensemble has been deliberately styled to appeal to the self-sufficient, resourceful technologist, right down to the black and grey colour palette with splashes of industrial yellow and blue.
