Greenhouse Gas Emissions

Stanford's heat-recovery system, or SESI, will cut greenhouse gas emissions by 68 percent ...

At Stanford University in California, it’s normally the Nobel-winning researchers who make the news. But with the commissioning of a novel renewable energy system, the campus’s humble heating and cooling system has grabbed some headlines. Using a first-of-its-kind heat recovery system, and drawing a substantial percentage of its electricity from solar, the university is greening up its operations in a move that will see greenhouse gas emissions cut by 68 percent and fossil fuel use cut by 65 percent.  Read More

In order to minimize the amount of human-produced greenhouse gases entering the atmosphere, numerous scientists have studied materials that could be used to capture excess carbon dioxide at one of its main sources – industrial smokestacks. Such substances have included metal-organic framework materials, ionic liquids, and even a sea urchin-inspired material. Unfortunately, however, not everything that's been suggested is inexpensive or easy to produce. That said, Norwegian researchers now believe that humble clay could do the job just fine.  Read More

30-cm (11.8-in)-deep moisture projection based on NASA's high carbon emission scenario in ...

A new NASA study is predicting the occurrence of severe "megadroughts" across the United States in the second half of this century, that are set to be more extreme and prolonged than any droughts that have taken place in the region for the past 1,000 years. According to the study, one of the key driving forces behind the devastating droughts will be the prolific creation of human-produced greenhouse gasses.  Read More

A study carried out at MIT suggests that altering the quantities of materials in cement mi...

As one of our most relied upon construction materials, concrete makes a significant contribution to our overall carbon emissions. Calcium-based substances are heated at high temperatures to form the cement, a process that produces carbon dioxide. But by slightly altering the quantities of materials used, scientists from MIT have uncovered a new method of cement mixing that could reduce these emissions by more than half.  Read More

EcoCAR 3 tasks students with updating the iconic Chevrolet Camaro muscle car into a hybrid...

For the past 26 years, the US Department of Energy (DOE), in partnership with the North American auto industry, has sponsored Advanced Vehicle Technology Competitions (AVTCs) to provide the next generation of automotive engineers with a practical learning experience. The previous EcoCAR Challenge saw students convert and massage GM Malibus into super-efficient models, and this time for EcoCAR 3, teams are tasked with updating the iconic Chevrolet Camaro muscle car into a hybrid-electric vehicle.  Read More

An artist's impression of California's new high-speed train

When people grumble about how they think the US isn’t as technologically advanced as it should be, they like to bring up bullet trains – Europe and Asia have them, so why doesn’t America? Well, it’s getting one. Work is starting this summer on a high-speed rail line running from San Francisco to Los Angeles, that will carry a passenger train traveling at over 200 mph (322 km/h).  Read More

Researchers at University of Texas at Arlington have developed a novel means of creating m...

Most previous methods of producing methanol from carbon dioxide have involved lots of electricity, high pressures and high temperatures, and used toxic chemicals or rare earth elements like cadmium or tellurium. A team of researchers at the University of Texas at Arlington (UTA) has developed a new method they claim is safer, less expensive, and simpler than current approaches and can be scaled up to an industrial scale to allow some of the CO2 emitted from electrical power plants to be captured and converted into a useful fuel.  Read More

Graduate student Zachary Baer works with a fermentation chamber to separate acetone and bu...

Researchers at the Energy Biosciences Institute (EBI) are generating bio fuels from renewable sources, such as sugar and starch, using a process that could be commercialized in as little as five to ten years. Although the fuels are currently more expensive to produce than those made from petroleum, they contain more energy per gallon than ethanol and the researchers say that, if adopted, could help to cut greenhouse gas emissions from transportation.  Read More

Hestia is a software system that shows building-by-building CO2 emissions

As the old adage goes, knowledge is power. Following this principle, Arizona State University researchers have developed a computer program called Hestia, that is capable of estimating the greenhouse gas emissions of specific roads and even buildings. With its high level level of detail and accuracy, the software can help cities make more precise calculations about their GHG footprint as well as more informed decisions related to carbon mitigation efforts.  Read More

A new material called NOTT-300 could help reduce emissions from coal-fired power plants, s...

Researchers at the University of Nottingham have developed another weapon in the ongoing war to reduce the amount of greenhouse gases emitted from fossil fuel-burning power plants. The researchers have created a new porous material called NOTT-300 that they claim is cheaper and more efficient than existing materials at capturing polluting gases, such as carbon dioxide and sulfur dioxide, from flue gas.  Read More
