A new biofuel production process created by Michigan State University researchers produces energy more than 20 times higher than existing methods. The results, published in the current issue of Environmental Science and Technology, showcase a novel way to use microbes to produce biofuel and hydrogen, all while consuming agricultural wastes. Gemma Reguera, MSU microbiologist, has developed bioelectrochemical systems known as microbial electrolysis cells, or MECs, using bacteria to...

New catalyst dramatically cheaper without sacrificing performance Engineers at the University of Wisconsin-Milwaukee (UWM) have identified a catalyst that provides the same level of efficiency in microbial fuel cells (MFCs) as the currently used platinum catalyst, but at 5% of the cost. Since more than 60% of the investment in making microbial fuel cells is the cost of platinum, the discovery may lead to much more affordable energy conversion and storage devices. The material —...

  A grain of salt or two may be all that microbial electrolysis cells need to produce hydrogen from wastewater or organic byproducts, without adding carbon dioxide to the atmosphere or using grid electricity, according to Penn State engineers. "This system could produce hydrogen anyplace that there is wastewater near sea water," said Bruce E. Logan, Kappe Professor of Environmental Engineering. "It uses no grid electricity and is completely carbon neutral. It is an inexhaustible...

Scientists have been hard at work harnessing the power of microbes as an attractive source of clean energy. Now, Biodesign Institute at Arizona State University researcher Dr. Prathap Parameswaran and his colleagues have investigated a means for enhancing the efficiency of clean energy production by using specialized bacteria. Microbial electrochemical cells or MXCs are able to use bacterial respiration as a means of  liberating electrons, which can be used to generate current and make...

The first demonstration of a renewable method for hydrogen production from wastewater using a microbial electrolysis system is underway at the Napa Wine Company in Oakville. The refrigerator-sized hydrogen generator will take winery wastewater, and using bacteria and a small amount of electrical energy, convert the organic material into hydrogen, according to a Penn State environmental engineer. "This is a demonstration to prove we can continuously generate renewable hydrogen and to study the...

U.S. scientists say they've discovered microbes can directly convert carbon dioxide and water to methane without generating hydrogen. Pennsylvania State University Professor Bruce Logan said his team made the discovery while studying making hydrogen in microbial electrolysis cells. We kept getting all this methane, he said. We may now understand why. Methanogenic microorganisms produce methane in marshes and dumps but scientists thought the organisms turned hydrogen or organic materials, such...

A tiny microbe can take electricity and directly convert carbon dioxide and water to methane, producing a portable energy source with a potentially neutral carbon footprint, according to a team of Penn State engineers. "We were studying making hydrogen in microbial electrolysis cells and we kept getting all this methane," said Bruce E. Logan, Kappe Professor of Environmental Engineering, Penn State. "We may now understand why." Methanogenic microorganisms do produce methane in marshes and...

Platinum is highly desired in jewelry and as a catalyst, but in both cases it is expensive. Now, Penn State researchers have found a way to replace the platinum catalyst in their hydrogen generating microbial electrolysis cells with stainless steel brushes without losing efficiency."Stainless steel brush cathodes can produce hydrogen at rates and efficiencies similar to those we have achieved with platinum-catalyzed carbon cloth," says Bruce E. Logan, Kappe professor of environmental...
