Johnny heath corpus christi Affordable Hydrogen Fuel Cells News Natural gas versus diesel: Examining the climate impacts of natural gas trucks

Some major trucking companies are turning to natural gas to fuel their fleets -- and to earn 'green' credit among customers. But celebrating lower emissions could be premature, according to a recent analysis. Researchers have found that converting heavy-duty trucks to run on natural gas could lead to negative climate impacts if steps are not taken to improve engine efficiency and reduce methane emissions from the fuel's supply chain.

Johnny heath corpus christi Affordable Hydrogen Fuel Cells News Electricity generating nano-wizards

Quantum dots are an ideal nanolab to study the means to turning heat into electricity. Just as alchemists always dreamed of turning common metal into gold, their 19th century physicist counterparts dreamed of efficiently turning heat into electricity, a field called thermoelectrics. Such scientists had long known that in conducting materials the flow of energy in the form of heat is accompanied by a flow of electrons. What they did not know at the time is that it takes nanometric-scale systems for the flow of charge and heat to reach a level of efficiency that cannot be achieved with larger scale systems.

Johnny heath corpus christi Affordable Hydrogen Fuel Cells News Artificial photosynthesis: New, stable photocathode with great potential

Scientists have developed a new composite photocathode for generating hydrogen using sunlight. The photocathode consists of a thin film of chalcopyrite coated with a newly developed thin film of titanium dioxide containing platinum nanoparticles. This layer protects the chalcopyrite thin film from corrosion, it acts as a catalyst to speed-up formation of hydrogen even shows photoelectric current density and voltage comparable to those of a chalcopyrite-based thin film solar cell.

Johnny heath corpus christi Affordable Hydrogen Fuel Cells News Ethanol refining may release more of some pollutants than previously thought

Ethanol fuel refineries could be releasing much larger amounts of some ozone-forming compounds into the atmosphere than current assessments suggest, a new study finds. Airborne measurements downwind from an ethanol fuel refinery in Decatur, Illinois, show that ethanol emissions are 30 times higher than government estimates. The measurements also show emissions of all volatile organic compounds, which include ethanol, were five times higher than government numbers, which estimate emissions based on manufacturing information.

Johnny heath corpus christi Affordable Hydrogen Fuel Cells News Can biodiesel damage your car in colder climates?

The oil industry believes biodiesel is not to blame for problems that some car owners are experiencing. But the nature of the fuel means that it has to be handled differently than regular petroleum-based diesel, a researcher says, especially in colder climates or if it is stored for longer periods.
