News Title: CarbonMiner Collaborates with Chang’an University on CCUS Carbon Removal Technology Development
News Content: CarbonMiner and Chang'an University Successfully Sign Agreement for CCUS Carbon Removal Technology Development
CarbonMiner has innovatively introduced the One-Stop Solution (OSS).
On August 15, a signing ceremony between CarbonMiner’s subsidiary and Chang’an University took place at Chang’an University’s main campus. This is hold for the joint development of CCUS carbon removal technology. Following the progress made in CO2 concrete fixation and mineralization, as well as the initial small-scale production, both parties are deepening their collaboration to jointly advance CCUS carbon removal technology. Increased research investment will lay a solid foundation for the future industrialization and large-scale application of CO2 technologies by CarbonMiner.
CCUS (Carbon Capture, Utilization, and Storage) is a technology designed to reduce carbon dioxide emissions. Carbon capture involves capturing CO2 during the combustion process and storing it in subsurface reservoir. Carbon utilization refers to using captured CO2 for concrete hardening and mineralization, as well as producing fuels, fertilizers, and other products. CCUS technology has garnered significant global attention and is considered a critical solution for mitigating climate change.
CO2 concrete fixation and mineralization is a technique that introduces CO2 into concrete, where hydration transforms moisture into minerals, so that enhancing the concrete structure and extending its lifespan. This method usually be applied after concrete preparation or post-pouring by introducing CO2 gas for hardening. The advantages of CO2 hardening and mineralization include increased compressive strength, durability, and crack resistance in concrete, while also avoided the hollows in concrete. These characteristics could ultimately reducing maintenance costs and repair frequency, as well as making greater contribution to the development of the construction and engineering sectors.
The research team has successfully developed a concrete that uses CO2 for hardening by controlling its composition and constructing techniques. Compared to traditional curing methods, this concrete reduces environmental pollution while improving durability and strength. The introduction of certain organic compounds during this process is the key elements that enhances the concrete’s mechanical properties and longevity.
Currently, these research results have already been applied in related engineering projects under CarbonMiner, and the company continues to explore and refine them. The impact and applicability of CO2 curing and mineralization technology in concrete applications are being actively studied. This technological applications will cover areas such as construction, water conservancy, and road and bridge engineering, with the goal of promoting its use and widespread adoption in the engineering sector.
Regarding the CCUS industry chain, CarbonMiner has innovatively proposed a one-stop solution (OSS) for thermal power plants. This solution integrates the entire energy application process from coal input to post-combustion waste treatment within a thermal power plant. The process includes the following steps:
1. CO2 Capture: Capturing and collecting CO2 emitted from coal combustion in the plant's chimneys.
2. Flue Gas Desulfurization Gypsum Treatment: Using waste heat and steam from the plant to convert flue gas desulfurization gypsum into new eco-friendly construction materials.
3. Fly Ash Treatment: Utilizing captured CO2 to produce aerated bricks from post-combustion fly ash, thereby mineralizing CO2.
4. Concrete Hardening: Fixing the collected CO2 in the curing of concrete precast components, reducing CO2 emissions in the process.
