Bio-hydrogen: a clean energy source from waste

Researchers from the Canadian National Research Center (CNRC) have produced hydrogen from organic wastes and agricultural wastes.

The aim of the researchers is to turn these wastes into a clean source of energy, without causing greenhouse gas emissions and acceptable prices. Much of today's hydrogen is from natural gas, from petroleum, from naphta and from coal. These techniques consume a lot of energy and create greenhouse gas emissions.

'Hydrogen production from organic substances is the best way to protect the environment and at the same time if it comes with low energy consumption when producing hydrogen' , Serge Guiot, Head of Environmental Biological Energy Research The school at the CNRS Biotechnology Research Institute said. The fermentation process releases less hydrogen and the team has thought of deploying and optimizing fuel cells that are impacted by light currents, which are called electric catalysts, increasing the amount of hydrogen produced. export.

Serge Guiot said: 'We want to create biological systems and gather them into continuous processes to produce hydrogen . ' Serge Guiot admitted: "This is really a breakthrough." For a long time, humans have been studying hydrogen production with traditional anaerobic fermentation, using biomass, but this method is extremely difficult because of the low hydrogen content. New research methods can overcome the disadvantages of biochemical processes.

To avoid the risk of causing global warming effects, energy technologies that do not use fossil fuels are attracting interest in many countries. Hydrogen power is one of the promising alternatives.

Hydrogen can be converted into electricity with high efficiency in fuel cells. It can produce energy 3-4 times more than the energy burned from oil and the only product is water.
