Hydrogen might burn clean, producing only water as a by-product, but currently over 90% of the hydrogen produced in the US comes from fossil fuels. Although algae can produce hydrogen using photosynthesis, it was believed that this only occurred for a few minutes at dawn, resulting in limited amounts of the gas. However, tests by […]

Changing the way the nation generates and consumes energy is at the heart of a new NSF grant awarded to Arizona State University and Kevin Redding, professor in the School of Molecular Sciences and director of the Center for Bioenergy and Photosynthesis (CB&P). The goal of Redding and his research group is to obtain industrial […]

Researchers at Tel Aviv University (TAU) have performed an experiment to modify algae so that it can be used to mass-produce hydrogen on an industrial scale. Although algae can produce hydrogen using photosynthesis, it was believed that this only occurred for a few minutes at dawn, resulting in limited amounts of the gas. But tests […]

Scientists from China conducted an experiment to regulate H2 production from microalga Chlamydomonas reinhardtii by using artificial miRNA technology. A heat inducible expression vector containing amiRNA targeting OEE2 gene was constructed and transformed into Chlamydomonas reinhardtii. The results showed that the transgenic alga showed higher H2 production due to the knock down of OEE2 gene. […]

Understanding the catalytic mechanism of hydrogenase might help scientists design clean biological energy sources, such as algae, that produce hydrogen. Scientists at the TU Berlin succeeded in explaining the function of a molecular switch in biomolecules. The research was carried out with the Free University Berlin, the Charite and the Humboldt University of Berlin. The findings […]

Scientists at the Energy Department’s National Renewable Energy Laboratory have demonstrated that just two of six iron-sulfur-containing ferredoxins in a representative species of algae promote electron transfers to and from hydrogenases. The finding suggests ways to increase the production of hydrogen by algae, which could help turn hydrogen into a viable alternative fuel for transportation. […]

Research from the Ruhr-Universität Bochum have found out how the cells notice the absence of oxygen and  have stated that when green algae Chlamydomonas reinhardtii  “can’t breathe”, they get rid of excess energy through the production of hydrogen. For this, green algae need the messenger molecule nitric oxide and the protein haemoglobin, which is commonly known […]

Here is an interesting article comparing the potential of algae and nuclear energy for hydrogen production. Link: Hydrogen Production Using Nuclear Energy or Algae or Both

You are at: Oilgae Blog. A team of researchers from the University of Tennessee, Knoxville, and Oak Ridge National Laboratory showed that photosynthesis may function as that clean, sustainable source of hydrogen. The team, led by Barry Bruce, a professor of biochemistry and cellular and molecular biology at UT Knoxville, found that the inner machinery […]

You are at: Oilgae Blog. In 1939 Hans Gaffron, a University of Chicago research scientist, observed that the green algae he was studying, Chlamydomonas Reinhardtii, would occasionally switch from the production of oxygen to the production of Hydrogen. Gaffron was unable to discover why the algae would change to Hydrogen production and the answer would […]
