Scientists Claim Major Advance in Artificial Photosynthesis

Written by , on November 30, 2015

Scientists at the Lawrence Berkeley National Laboratory and the University of California, Berkeley have development of a system that mimics the natural photosynthetic process by which plants use the energy in sunlight to synthesize carbohydrates from carbon dioxide and water. The artificial system can capture carbon dioxide emissions and convert that carbon dioxide into valuable chemical products, including biodegradable plastics, pharmaceutical drugs and liquid fuels.  Read more »

Carbon Capture and Storage 2.0?

Written by , on October 16, 2013

The Global CCS Institute, which is based in Canberra, has reported that since its previous survey a year ago, five carbon capture and storage projects have been canceled, one reduced in size and seven postponed, while three have been added. The leader in capture and storage is the United States – mostly because of the […]  Read more »

How to Help Document Power Plants

Written by , on July 10, 2013

Power plants burning fossil fuels contribute over 40% of global carbon dioxide emissions to the atmosphere. But information about where the world’s power plants are located, and how much each one is emitting, is not well-known outside of a handful of industrialised countries. The Ventus Project, led by Dr. Kevin Robert Gurney at Arizona State […]  Read more »

Removing Top Predators Can Dramatically Change CO2 Emissions

Written by , on February 18, 2013

When Trisha Atwood of the University of British Columbia studied the effect of removing predator fish from ponds and rivers in Canada and Costa Rica, she found a consistent pattern – carbon dioxide emissions increased more than tenfold after the predators were removed. Wiping out the top predator results in a "trophic cascade" in which […]  Read more »

Cool Coal?

Written by , on August 28, 2012

A team of University of Oregon physicists has published a paper recommending the treatment of flue gases from coal-fired power plants by cooling it sufficiently for pollutants to be deposited as "ices". The researchers believe that this cryogenic system would capture at least 98% of sulfur dioxide, virtually 100% of mercury and 90% of carbon […]  Read more »

Process Captures CO2 & Makes Organic Material

Written by , on August 2, 2012

The Japanese electronics manufacturer, Panasonic, has announced that it has developed an artificial photosynthesis process which converts carbon dioxide to organic materials by illuminating them with sunlight at an efficiency which is comparable with plants used for biomass energy. The discovery has the potential to allow the development of simple and cheap systems for capturing […]  Read more »

Beijing Olympics Show Cutting Car Use Could Avoid Warming

Written by , on July 23, 2012

Scientists, led by Helen M. Worden from the US National Center for Atmospheric Research, have published a report which quantifies the extent to which the Beijing government’s temporary controls on urban traffic reduced carbon dioxide levels during the 2008 Olympics. Their study shows that, if made permanent in all large metropolitan areas, the Beijing restrictions […]  Read more »

Renewable Carbon Dioxide “Sponge”

Written by , on November 18, 2011

Scientists at Weinberg College of Arts and Sciences at Northwestern University in Chicago have reported the development of a strong and reversible sponge-like material to capture and store gaseous carbon dioxide. The main component, gamma-cyclodextrin, is a naturally occurring biorenewable sugar molecule that is derived from cornstarch. These sugar molecules are held in place by […]  Read more »

The Ins and Outs of Coal-fired Power

Written by , on September 27, 2010

Take a look at our new video about the amazing amount of coal and water that it takes to run a coal-fired power station – and the huge volume of carbon dioxide emitted, as well as all of the other pollutants.  Read more »
