A Unique Capture Process
GT uses custom equipment and proprietary (dry) amine-based chemical “sorbents” that are bonded to porous, honeycomb ceramic “monoliths” which act together as carbon sponges. These carbon sponges efficiently adsorb CO2 directly from the atmosphere, smokestacks, or a combination of both. The captured CO2 is then stripped off and collected using low-temperature steam (85-100° C), ideally sourced from residual/process heat at little or no-cost. The output results in 98% pure CO2 at standard temperature and pressure. During the process only steam and electricity are consumed, without the creation of emissions or other effluents. This entire process is mild, safe, and carbon negative.
Global Thermostat’s Carbon Capture & Utilization Plants can reliably produce unlimited amounts of CO2 at a low cost, and on-site as needed. This results in commercial-use ready CO2, eliminating the need for long pipelines and/or transportation costs.
Modular & Small Footprint: GT plants are completely modular – from a single 50,000 tonne/yr. Module to a 40-Module, 2MM tonne/yr. Plant, and larger – a GT plant grows by adding more modules. GT Plants also have a small footprint – capturing from 20-500 tonnes of CO2/yr./m2 or more, depending on the embodiment used.
Plants can be Stand-Alone (Pure Air) or Co-Located with large emitters – both new & existing. In fact, integrating GT’s post-combustion process with an existing power plant is quite simple, and has been done with just a single day of power plant down-time. GT enables a true Carbon Negative electricity generation: a GT plant utilizes the residual heat of an adjacent fossil fueled power plant, while simultaneously capturing the CO2-rich flue gases it produces. This process allows the plant to capture substantially more CO2 than it emits. Similarly, GT can utilize the “harmful” heat byproduct of PV solar farms to power its plants, turning the farms into giant carbon sinks, while increasing their profitability through CO2 sales.
Unlike some other green initiatives, GT requires no government subsidies or Carbon Credits to be economical and profitable.
