Coal is somewhat notorious for not being the cleanest of fuels. Similarly all combustion systems release a good deal of carbon dioxide. A new form of clean coal technology reached an important milestone recently, with the successful operation of a research-scale combustion system at Ohio State University. The technology is now ready for testing at a larger scale. (more…)
It sounds like magic but it’s actually based on sound science. A British start-up called Air Fuel Synthesis is developing a technology to make gasoline using renewable energy to capture carbon dioxide and water from the air. It then electrolyzes the water to make hydrogen and reacts the carbon dioxide and hydrogen together to make (more…)
Putting a speed limit on cargo ships as they sail near ports and coastlines could cut their emission of air pollutants by up to 70 percent, reducing the impact of marine shipping on Earth’s climate and human health, scientists have found. Their evaluation of the impact of vessel speed reduction policies, such as those proposed by the California Air Resources Board, (more…)
As Fall turns leaves to colorful displays, starting in northern New England, and moving ever southward as Fall progresses, we think of the approaching Winter. We might also think of all the carbon that the once green leaves contain that will be released to the atmosphere as they decay. (more…)
The rapid expansion of palm oil plantations in the world’s tropical regions, particularly Indonesian Borneo, is becoming an increasingly significant source of global carbon emissions, a new study says.
Writing in the journal Nature Climate Change, researchers from Stanford and Yale universities project that the continued expansion of plantations will add more than 558 million metric tons of carbon dioxide (more…)
There is deep concern over air quality in China especially during the 2008 Olympics held there. Concern was raised over the air quality, and its potential effect on the athletes. Beijing committed then to remove 60,000 taxis and buses from the roads by the end of 2007 and relocate 200 local factories, including a prominent steel factory, China’s Olympian attempt (more…)
