Conventional hydrogen production is expensive. A cheaper method involves using algae. The algae live in a series of ponds. Hydrogen is collected as it bubbles to the surface. An advantage is microalgae can be located on non-arable land and don't compete with food production.
Ben Hankamer: One question we often get is; is it actually feasible to produce any biofuel, whether it's hydrogen or oil or whatever, on the scales that we need globally? Say if you had a solar voltaic panel right now at 12% efficiency, the area you would need for global energy, to supply the entire global energy demands would be about 4% or 5% of the Sahara desert. It's actually doable. Every year we receive 8,000 times the amount of energy we require to drive our economy from solar energy, which we just really don't use.
