In the desperate search for renewable energy sources scientists are turning to bacteria to more efficiently produce hydrogen. Hydrogen has long been touted as a potential wonder fuel for cars and other energy needs. However, the majority of hydrogen production has been relegated to cost-effective methods involving extraction from fossil fuels. This manufacturing process releases large amounts of CO2 making hydrogen a dirty fuel source. Fortunately, scientists with the Agricultural Research Service (ARS) and North Carolina State University (NC State)   have developed a cleaner technology that produces hydrogen from nitrogen-fixing bacteria. …Read More
