Harnessing hydrogen at life's origin

Though humans are just now coming to realize the benefits of hydrogen gas , microbes have known that H2 is good fuel for as long as there has been life on Earth. Hydrogen is ancient energy.

How an energetically uphill reaction could have worked in early evolution, before there were enzymes or cells, has been a very tough puzzle."Several different theories have proposed how the environment might have pushed electrons energetically uphill to ferredoxin before the origin of electron bifurcation," says Martin,"we have identified a process that could not be simpler and that works in the natural conditions of hydrothermal vents.

A new energy-efficient way to produce hydrogen gas from ethanol and water has the potential to make clean hydrogen fuel a more viable alternative for gasoline to power ...

New study uncovers how hydrogen provided energy at life's originHydrogen gas is a clean fuel. It burns with oxygen in the air to provide energy with no CO2. Hydrogen is a key to sustainable energy for the future. Though humans are just now coming to realize the benefits of hydrogen gas (H2 in chemical shorthand), microbes have known that H2 is a good fuel for as long as there has been life on Earth.
