Hosted by The University of California, this talk on bacteria producing hydrogen. We all know that hydrogen is a clean and efficient source for energy, for example used in future cars with fuel cells. However, production of hydrogen is actually dirty and expensive using current mainstream methods – something that bacteria could change in the future.

The most ancient forms of life – bacteria – are exceptionally tiny organisms, yet they have contributed in big ways to our planet. Although long recognized for causing disease, microbes have had a tremendous impact on our survival, and now can help us solve some of our urgent energy problems. Unlike fossil fuels, the microbial production of biofuels represents a new source of energy that can be constantly renewed.
