Carbon Market and Atmospheric CO2 Capture Technology Could Reduce Global CO2

Last updated on by

Global Thermostat, where Chichilnisky is CEO and co-founder, has what they believe to be a commercially viable atmospheric CO2 capture technology, which uses readily available process heat to remove carbon dioxide from the air, essentially converting a power plant from a CO2 producer into a carbon-negative facility.

“Global Thermostat’s (GT) patent-pending technology uses low-cost left over process heat as energy for the capture of CO2 from the atmosphere. It can be installed at new or legacy power plants, cement smelters, refineries, etc. Since energy typically accounts for two-thirds of the total operating cost with other carbon capture technologies, Global Thermostat’s solution allows for dramatic cost efficiencies in reducing carbon emissions.” – Global Thermostat

GT’s air capture solution, especially when combined with a carbon market, could be part of an effective path to reducing global CO2, as Chichilnisky explains:

In order for a carbon market to be effective, there has to be cost-effective methods for removing CO2 from the atmosphere, essentially creating more ‘carbon-negative’ technologies, such as that developed by GT. According to the results of the company’s pilot plant at SRI International in Menlo Park, CA, the air capture process used by GT for removing CO2 enables the reduction of “more CO2 than it generates during the production of electricity.”

The GT solution is said to be modular and scalable, requires only heat and air to operate, and uses existing technology with mostly off-the-shelf equipment. The system could be installed or integrated across a number of industries, helping them to lower their emissions or to even become carbon-negative. For example, GT points out these potential applications of their technology:

Legacy power plants, which become carbon sinks: Unlike other carbon capture methods, GT’s air capture technology can be retrofitted into an existing facility, eliminating the need to redesign the plant’s processes.

Renewable energy plants: Rather than simply avoiding the creation of more CO2 emissions, GT’s direct air capture technology makes it possible for renewable energy plants such as concentrated solar power to be carbon negative.

Manufacturing facilities become carbon sinks: GT’s air capture technology allows the capture of CO2 in conjunction with heavy industrial processes such as aluminum smelters, cement producers and refineries.
