Carbon Dioxide

Miniature Factories from the Sea

Algae are exceptionally gifted chemists and help climate protection. This is because algae take in carbon dioxide (CO2) and sunlight to produce chemicals such as carbohydrates, lipids, and amino acids. In special cases they even produce bioethanol, which is a...



Carbon Negative Power Plants

Global Thermostat LLC (GT) (www.global thermostat.com) was formed in 2006 to develop and commercialize a unique technology for the direct capture of carbon dioxide from the atmosphere and other sources. The GT process “co-generates” carbon capture with other industrial processes—such as power...



In the United States today, there are approximately 189 ethanol plants. CryoGas International estimates that about 25 percent of these recover CO2. (See “US Carbon Dioxide Market Report,” on p. 24 of this issue.) Ethanol plant development in the US had been growing steadily...


Measuring and Reporting Greenhouse Gases

Companies in the United States that emit more than 25,000 tons/year of carbon dioxide (CO2) equivalent must now report greenhouse gas (GHG) emissions. The US Environmental Protection Agency (EPA) will require large emitters of heat-trapping emissions to begin...



A Company Scales Up

The Gerhart Scale Corporation (Gerhart) (www.gerhart.com) began as an industrial scale distributor that supplied the transportation and manufacturing sectors. For the industrial gas sector, Gerhart’s scales service highway- and plant-located truck scale systems for merchant bulk weight and fill control systems for...


The Case for Recycled Carbon Dioxide

With the on-going political discussion of carbon cap-and-trade, sequestration, and other environmental initiatives, Cool Clean Technologies, Inc. (www.coolclean.com) has witnessed confusion among its customers that are considering the purchase of carbon dioxide-based equipment for cleaning, cooling, and extraction applications.
