Combustor Computations for CO₂-Neutral Aviation

This method can be used to determine synthetic and biological fuels and blends.

Knowing the pure component Cp0 or mixture Cp0 as computed by a flexible code such as NIST-STRAPP or McBride-Gordon, one can, within reasonable accuracy, determine the thermophysical properties necessary to predict the combustion characteristics when there are no tabulated or computed data for those fluid mixtures or limited results for lower temperatures. (Note: Cp0 is molar heat capacity at constant pressure.) The method can be used in the determination of synthetic and biological fuels and blends using the NIST code to compute the Cp0 of the mixture.

Looking to Cow Rumen for Better Biofuels Enzymes

A cow's digestive system allows it to eat more than 150 pounds of plant matter every day. Now researchers report that they have found dozens of previously unknown microbial enzymes in the bovine rumen – the cow's primary grass-digestion chamber – that contribute to the breakdown of switchgrass, a renewable biofuel energy source.

Fuel Cell Research and Development Funding Opportunity

Fuel cells use the chemical energy of hydrogen or other fuels to efficiently produce electricity or heat with minimal byproducts, primarily water. The DOE is accepting applications for a total of up to $74 million to support the research and development of clean, reliable fuel cells for stationary and transportation applications.

High-Resolution Wind Measurements for Offshore Wind Energy Development

A mathematical transform, called the Rosette Transform, together with a new method, called the Dense Sampling Method, have been developed. The Rosette Transform is invented to apply to both the mean part and the fluctuating part of a targeted radar signature using the Dense Sampling Method to construct the data in a high-resolution grid at 1-km posting for wind measurements over water surfaces such as oceans or lakes.

Measuring Air-Sea Exchange of Carbon Dioxide in the Open Ocean

A team led by scientists at the National Oceanography Centre of Southampton, UK have measured the air-sea exchange of carbon dioxide in the open ocean at the highest wind speed to date. Their findings are important for understanding how interactions between the ocean and the atmosphere influence climate.

Desalinate Water, Produce Hydrogen, and Treat Wastewater?

Water purification requires a lot of energy, while utility companies need large amounts of water for energy production. Researchers from the University of Colorado Denver College of Engineering and Applied Science have found a way to generate pure hydrogen gas and desalination facilitated by an external power supply.
