The fight against climate change involves various strategies. While transitioning to renewable energy is crucial, other approaches like the circular economy are also essential. Imagine a factory that captures and converts COâ‚‚ into a material that strengthens concrete structures. By using carbon dioxide as a raw material, we can make it a valuable asset in the global effort to reduce emissions. Carbon sequestration technologies have been explored extensively, and this article focuses on MIT’s advancements in utilizing captured COâ‚‚ effectively.
Towards more efficient CO2 transformation systems
For carbon dioxide to be a viable resource, the sequestration process and conversion into useful compounds must be highly efficient. MIT has developed a breakthrough technology to enhance these processes.
The innovation involves an electrode design that improves electrochemical reactions converting COâ‚‚ into chemicals like ethylene. The electrode system includes thin copper wires woven through a conductive membrane, allowing for a direct interaction with the catalyst. This design boosts the speed and selectivity of chemical reactions.
Laboratory tests have shown high conversion rates of COâ‚‚ with minimal energy consumption using this system. Additionally, the modular design of the electrode enables scalability in industrial operations without compromising efficiency.
5 applications of CO2 as a raw material
Advancements in carbon sequestration systems and catalysts have led to innovative uses of carbon dioxide. Here are five promising applications:
1. As a component of concrete
Injecting liquid COâ‚‚ into concrete can mineralize the gas within buildings, reducing the material’s carbon footprint.
2. As raw material in the textile industry
COâ‚‚ can be used to produce cellulose for textiles, creating fibers like lyocell.
3. As a component for the development of synthetic proteins
Microbes can use hydrogen and COâ‚‚ to manufacture synthetic proteins, making it suitable for space missions and Earth-based applications.
4. Sodium bicarbonate production
Carbon dioxide can be used in the production of sodium bicarbonate for various applications.
5. Algae and biofuel production
Cultivating algae using COâ‚‚ emissions can create raw materials for compost and cosmetics, offering potential solutions for sustainability.
While these applications show promise in reusing COâ‚‚, the most effective way to combat climate change is still by preventing emissions at their source and shifting towards renewable energy sources like wind and solar power.
