Steel Making without Releasing Carbon Dioxide

Written by , on November 10, 2018

Boston Metal has developed a technique for making high-strength steel alloy using an electrolytic cell rather than a blast furnace. The process does not release the huge quantities of carbon dioxide produced in the traditional process.  Read more »

Artificial Mineral Can Remove CO2 from the Air

Written by , on September 10, 2018

Researchers have found a way of making magnesite, which absorbs carbon dioxide, in a matter of days rather than the hundreds of thousands of years which it takes in nature. A tonne of naturally-occurring magnesite can remove around half a tonne of CO2 from the atmosphere.  Read more »

Graphene Makes Concrete Stronger and Reduces CO2 Emissions

Written by , on April 26, 2018

Researchers at the University of Exeter have developed a new technique that uses nanoengineering technology to incorporate graphene into traditional concrete making it more than twice as strong and four times more water resistant than existing concretes while significantly reducing carbon emissions.  Read more »

Speeding Up Carbon Sequestration in the Ocean

Written by , on April 16, 2018

Scientists at Caltech and the University of Southern California have discovered that adding a common enzyme will make the slow part of the chemical reaction that sequesters carbon dioxide into the ocean go 500 times faster. They believe that, if they can scale this process up, it could make a real difference in reducing the level of carbon dioxide in the atmosphere.  Read more »

New Cement Cuts CO2 Emissions

Written by , on December 8, 2017

Solidia Technologies has developed a cement making process that the company says produces 70% less CO2 emissions as conventional cement manufacture while producing a product which is equally as strong.  Read more »

Could Slag Heaps Remove CO2 from the Atmosphere?

Written by , on April 24, 2017

Phil Renforth, a scientist at Cardiff University, is preparing to test the feasibility of using iron and steel slag deposits to remove carbon dioxide from the atmosphere.  Read more »

Solar Cell Produces Fuel from CO2 and Sunlight

Written by , on August 5, 2016

Researchers at the University of Illinois at Chicago have developed a solar cell that cheaply and efficiently converts atmospheric carbon dioxide directly into usable hydrocarbon fuel, using only sunlight for energy.  Read more »

New Process Absorbs CO2 and Excess Salt from Desalination

A new process reacts carbon dioxide with brine to produce sodium bicarbonate.  Read more »

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 »
