By Brooks Hays for UPI: Researchers at the University of North Dakota believe geothermal energy production should be a significant part of America's future energy portfolio.
But to get the industry off the ground, proponents are looking to an industry not normally associated with renewable energy -- gas and oil drillers.
"Oil- and gas-producing sedimentary basins in Colorado, Illinois, Michigan, and North Dakota contain formation waters of a temperature that is adequate for geothermal power production," researchers wrote in their new study on the subject, published this week in the journal Geosphere.
Geothermal energy requires heat, and natural sources of heat lie deep within the ground. Gas and oil drillers have already built the infrastructure to access deep-lying natural resources. Of course, gas and oil drillers want gas and oil, not heat. But in their quest for gas and oil, they get heat nonetheless. Cont'd...
By Teresa Meng for The Chronicle: A Duke University professor has been awarded a $5.2 million U.S. Department of Energy grant to explore ways of making algae a cost efficient fuel source.
The Duke-led Marine Algae Industrialization Consortium, comprised of both universities and energy companies, aims to lower the cost of algae oil, which can be used in place of fossil fuels. The team is working to identify algae proteins that can be used in protein-based nutritional products in order to make the entire algae farming process more cost-efficient. Zackary Johnson, Arthur P. Kaupe assistant professor of molecular biology in marine science, is the principal investigator of MAGIC and has been researching algae biofuels for eight years.
“The goal of the research is to drive down the cost of algae biofuel by increasing the value of proteins within algae,” Johnson explained.
Johnson and his team at MAGIC are trying to use multiple ways so that algae grown for biofuel extraction can also be sold after oil is extracted from the algae. Proteins in algae could be used for nutritional products such as poultry feed, fish feed or even food for humans. Extracting and selling these proteins would lower the overall production cost of extracting oil from the algae. In the future, algae proteins as food sources might even be a sustainable approach to feed the world.
Algae biofuel has the potential to become a major source of sustainable energy because it can be produced quickly, easily and in high quality, Johnson said. Cont'd...
