Carbon Capture GE Develops a New Technology for CO2 Capture
Developers of GE found the same of amino silicones which are used in hairspray, are able to capture CO2 from a gas stream. How the new technology works.
Oklahoma City--GE chemists have developed a solution that effectively uses a class of amino silicone compounds at various temperatures to capture carbon. These compounds are the same as those found in hair conditioners and fabric softeners. In hair products and washing machines, these compounds are used to soften your hair or clothing. GE is using them attach to and essentially wash out CO2 gas from a power plant flue stack.
Calling it CO2 “Capture Technology in a Bottle,” a team of researchers at GE’s Oil & Gas Technology Center in Oklahoma City, Oklahoma have been awarded close to $1 million in Phase I funding by the U.S. Department of Energy’s National Energy Technology Laboratories (NETL) to plan and propose a large scale pilot testing of its CO2 Capture technology solution
How it works
At temperatures of around 105 degrees F, the amino silicone materials attach to CO2 gas. When the heat is increased another 100 degrees F, these materials release the carbon and can then be re-used to capture more.
One of the big advantages of the new technology is that it does not require any water, which substantially reduces the energy required to capture the carbon.
“For decades, scientists from around the world have focused their efforts on finding more effective, less expensive ways to reduce CO2 emissions in the atmosphere,” said Phil DiPietro, Technical Manager, CO2 Capture and Separation, GE’s Oil and Gas Technology Center in Oklahoma City. “GE scientists have developed an innovative solution to realize both goals, which works well in the lab. Through this project, we will have the opportunity to perform tests at a much larger scale to learn how to make it work in a power plant.”
Testing of the new CO2 capture solution will take place at the CO2 Technology Center at Mongstad (TCM), Norway, which is the world’s largest industrial scale test facility. This $1 billion (USD) facility is fully instrumented and designed to provide technology developers with an infrastructure to subject their technologies to all the stresses that real-time operations would entail. GE is partnering with the CO2 Capture Centre in Mongstad.
TCM Managing Director Mr. Roy Vardheim said: “We are very satisfied that the close co-operation between the US and Norway now facilitates bringing leading technologies and companies to our world class testing arena at Mongstad. We are impressed with the technological developments by our US partners, and are confident that they will benefit from the unique qualities of the TEST facilities and services that TCM will provide.
As part of Phase 1 funding, GE will advance planning of their Amino-silicone CO2 capture technology towards large scale pilot testing. It is expected that two of the six phase 1 projects will be selected for Phase 2.
The Phase 2 awards for construction and execution of pilot testing is anticipated by mid-2016. The large scale testing will aim to demonstrate the technology at industrial scale and provide final confidence in the maturity of the Carbon Capture technology for full scale commercial deployment, reducing emissions from power plants and other large industrial point sources of CO2.
GE’s technology development taps into decades of expertise working with amino silicone materials when GE operated a silicones business. The NETL project is part of a decade long joint cooperation between the US and Norwegian energy authorities on CO2 Capture and Storage technologies.
The co-operation between the US and Norwegian Energy authorities in the area of carbon capture and storage dates back to 2004, when the two governments signed a memorandum of understanding (MOU).
