“READING”
When feeling anxious, instead of going in circles, it is better to turn the pages of a book.
Every step of learning is taking root for the future.
Every moment spent focused today is the confidence for tomorrow.
Don’t be afraid of going slow; just start, and growth will quietly happen.
Cultivate with peace of mind, and time will give you the answers!
Speaking of the technology that captures carbon dioxide directly from the air, known as Direct Air Carbon Capture (DAC), it is gradually moving from concept to reality. Currently, the world is exploring this technology because it can address dispersed and hard-to-collect emission sources, and even reduce the concentration of carbon dioxide already present in the atmosphere. However, this path has just begun, and there are many challenges, such as relatively high costs and energy consumption.
On the technical progress front, there are some good news:
- Capture devices are becoming more practical: For example, the “CarbonBox” developed independently in our country can capture over 100 tons of carbon dioxide per year, and a single module can operate independently, being the size of a shipping container, making it quite convenient to deploy.
- Capture materials are continuously improving: Researchers have developed new materials, such as composite materials using copper ions as a medium, which reportedly can increase capture capacity several times; there is also an electrode that stabilizes active molecules.
- Efforts are being made to reduce energy consumption and costs: Some new systems have reduced energy consumption by 50% compared to similar systems; other research attempts to use hot water instead of electricity to drive the system, or utilize waste heat from data centers, all aimed at conserving energy.
- Application scenarios are becoming more diverse: In addition to storage, the captured carbon dioxide can be used to synthesize green methanol, aviation fuel, and even as building materials or in beverages, attempting to generate economic value. In Nanjing, there is a project that integrates DAC into buildings, improving indoor air quality while also solidifying carbon dioxide into building materials.
- International attention and cooperation are increasing: Overseas technology and petrochemical giants are optimistic about the “negative carbon asset” properties of DAC and are actively investing. Our first seminar on direct air carbon capture technology has also been held, where experts and scholars discussed how to develop this technology.
In the practice of carbon neutrality, DAC is beginning to find some footholds:1. Integration with industries: For example, the cement industry has high emissions and is difficult to decarbonize; DAC technology can utilize the waste heat from cement kilns to reduce regeneration energy consumption, and the captured CO₂ can be mineralized into solid waste to create cementitious materials, forming a carbon closed loop.2. Collaboration with green electricity: Some projects are researching the use of wind power, photovoltaic renewable energy, or even surplus electricity to drive DAC, and the captured carbon dioxide can be used to produce green fuels.3. Modular distributed deployment: Since DAC does not rely on fixed emission sources, it can be arranged more flexibly, such as in buildings or communities, saving on pipeline transportation costs and reducing expenses.
To achieve carbon neutrality goals, DAC technology can serve as a supplementary means, but I believe:1. The fundamental approach is still to vigorously reduce emissions, decreasing the use of fossil energy at the source and accelerating the adjustment of the energy structure.2. DAC technology itself needs to continue to tackle challenges, further reducing energy consumption and costs, improving capture efficiency and material lifespan, making the technology more “user-friendly”.3. Policy support and market mechanisms need to keep pace, such as clarifying carbon pricing and encouraging carbon trading, providing sustainable economic incentives for projects like DAC.4. Strengthening international cooperation and exchanges to jointly promote technological innovation and standard formulation.
DAC technology is somewhat like installing an “air purifier” for the Earth; although its current power is still small and the price is quite high, thinking about the future, it may become a useful tool in our toolbox for addressing climate change. We can keep an eye on it and look forward to its faster maturity and popularization.
