Cap and trade programs to reduce emissions do not provide enough incentives to induce the private sector to develop innovative technologies to address climate change, according to a new study by Lawrence Berkeley National Laboratory.

China’s
output of so-called “green” technologies has grown by a 77% a year,
reflecting the country’s pace of growth. On a political level, China has
made a conscious decision to capture and develop markets in renewable
energy and other clean technologies. The U.S. is also growing in this
sector, but not nearly as quickly.

A scientist from Iceland who is presenting his findings this week at the University of Tennessee is leading an international team of scientists on the Carbfix Project, which aims to pump carbon deep underground in southwest Iceland where it will mix with minerals, particularly basalt, and become rock.

A new study indicates that major chemicals most often cited as leading causes of climate change, such as carbon dioxide and methane, are outclassed in their warming potential by compounds receiving less attention. Purdue Univ. and NASA examined more than a dozen chemicals, most of which are generated by humans, and have developed a blueprint for the underlying molecular machinery of global warming.

A new mobile air research laboratory will help a team of researchers led by a Michigan State Univ. professor better understand the damaging health effects of air pollution and why certain airborne particles—emitted from plants and vehicles—induce disease and illness.

Researchers at MIT have shown the benefits of a new approach toward eliminating carbon-dioxide (CO2) emissions at coal-burning power plants. Their system, called pressurized oxy-fuel combustion, provides a way of separating all of the carbon-dioxide emissions produced by the burning of coal, in the form of a concentrated, pressurized liquid stream. This allows for carbon dioxide sequestration: the liquid CO2 stream can be injected into geological formations deep enough to prevent their escape into the atmosphere.

It’s hard to believe, but for all the studies that have taken place to gauge the effects of man-made emissions, we have yet to understand how organic compounds from plants interact with the atmosphere. Caltech researchers have been looking at these biogenic emissions and say they have a first-ever glimpse into this dynamic.

Under the current pollution control funding structure, one big cleanup can break the bank while smaller projects that could provide greater benefits go unfunded. To better allocate limited resources, a biological engineer has built a genetic algorithm that works with best management practices tool to identify the best ways to address non-point source pollution in watersheds.

Even above the driest deserts, water molecules exist in the air. A new system captures it without drawing outside power. The system uses a combination of saline solution to absorb moisture, a solar cell or concrentrator to boil the moisture, and a vacuum tank which collects condensed water because of its lower boiling point.
