Affordable Carbon Capture from the Air

Written by , on June 13, 2018

A Canadian company has published results of a pilot study that shows that CO₂ can be captured from the atmosphere for less than $us100 a tonne – far less than previous estimates of $600 to $1,000 a tonne. The company is commercalising technology which uses the captured CO₂ to produce liquid hydrocarbon fuels.  Read more »

Carbon Capture & Storage More Expensive than Thought

Written by , on January 5, 2016

Researchers at the University of Michigan have found serious flaws in previous statements about the economics of carbon capture and storage.  Read more »

Jet Fuel from Seawater

Written by , on December 15, 2013

The US Navy is developing a technology that it expects will allow it to produce jet fuel out of seawater. Carbon is abundant in seawater, with the concentration in the ocean being about 140 times greater than in air. Most of the carbon is in the form of bicarbonates with about 1% being carbonates. The […]  Read more »

Making Steel without CO2 Emissions

Written by , on July 5, 2013

Steelmaking is one of the world's leading industrial sources of greenhouse gases. It is produced in furnaces fed by vast amounts of coke, distilled from coal. Now, researchers at MIT, who were looking for a way to extract oxygen from Moon rocks, have developed a new process to produce steel with no CO2 emissions. The […]  Read more »

Biochar Less Useful Than Thought

Written by , on July 5, 2013

Biochar has been regarded as a possible way of reducing atmospheric carbon by locking it up in the soil for a very long time. But a new study suggests that it may not be nearly as effective as previously thought. Biochar is charcoal produced from biomass. It is a high-carbon, fine-grained residue which can be […]  Read more »

UN Agency Recommends Stopgap for Climate Change

Written by , on February 23, 2011

A new report by the United Nations Environment Program and the World Meteorological Organization, proposes a climate-change stopgap: by controlling two noxious ground-level pollutants, black carbon (or soot) and ozone. Reducing levels of these substances would slow the rate of climate change in the first half of the 21st century while carbon dioxide levels are […]  Read more »

China Orders 2,087 Polluting Factories to Close

Written by , on August 10, 2010

The Chinese government has ordered over 2,087 firms in high-polluting and energy-intensive industries to shut down outdated plant by the end of September. Companies that fail to do so risk having bank loans frozen, approvals for new projects and land purchases refused and their electricity cut off. Companies effected produce steel, coal, cement, aluminium, glass […]  Read more »

40% Decline in Marine Phytoplankton

Written by , on August 3, 2010

Researchers led by Boris Worm, a marine biologist at Dalhousie University in Halifax, Canada, have published a paper in the journal Nature showing that marine phytoplankton have declined substantially in the world’s oceans over the past century. Phytoplankton are the basis of the entire marine food chain. They produce around half of the oxygen in […]  Read more »

Coal Fires Burning for 50 years To Be Put Out

Written by , on June 9, 2010

The world’s worst underground coal fires are in Inner Mongolia. Some have been burning for 50 years. The amount of coal being burned is estimated to be about 20 million tonnes a year. The Inner Mongolia regional government has now announced plans and financing of 200 million yuan ($au36 million) to begin extinguishing the fires. […]  Read more »

Using Light to Turn CO2 Back into Fuel

Written by , on March 19, 2010

Scientists from the University of Michigan and Oxford University have reported in the Journal of the American Chemical Society that they have developed a way of efficiently turning carbon dioxide into cabon monoxide (which can be used as a fuel) using visible light. The scientists used an enzyme-modified titanium oxide and a photosensitizer to make […]  Read more »
