Carbon Removal Plant

Carbon removal is the process of removing carbon dioxide from the atmosphere by technological or natural processes, which includes methods of capturing carbon dioxide directly from the atmosphere and storing it permanently. This approach is designed to balance or neutralize unavoidable carbon emissions, helping to mitigate climate change.

Nature-based solutions:

For example, afforestation and reforestation enhance the ability to absorb carbon dioxide by increasing forest coverage.‌

Measures to enhance the natural process:

Such as restoring coastal vegetation ecosystems and marine ecosystems to enhance their ability to absorb carbon dioxide from the air.

Technology-based solutions:

Such as direct air capture, special machines are used to extract carbon dioxide from the air and then be pumped deep into the ground to store it permanently through a natural mineralization process.‌

Slowing down global warming:

Carbon dioxide in the atmosphere is a major greenhouse gas, and excessive CO ₂ can cause the earth's temperature to rise, thus triggering climate change. Through carbon removal technology, the CO ₂ concentration in the atmosphere can be directly reduced, thus slowing down the process of global warming.

To achieve carbon neutrality:

Many countries and regions have committed to becoming carbon neutral in the future, reducing greenhouse gas emissions to zero or offsetting corresponding emissions through carbon removal technologies. Carbon removal is one of the most important ways to achieve this goal, especially for emissions that are difficult to completely avoid, and carbon removal technology can fill this gap.

Protect ecosystems:

Climate change poses a serious threat to ecosystems and biodiversity. Through carbon removal technology, the impact of climate change can be mitigated, and ecosystem stability and biodiversity can be protected.

Promoting technological innovation and economic development:

The development of carbon removal technology requires a lot of research and innovation to promote scientific and technological progress in related fields. In addition, the commercial application of these technologies can also drive new economic growth points and create jobs.

Improving air quality:

Certain carbon removal technologies (such as afforestation and Marine carbon sequestration) can also improve air quality and increase the area covered by green vegetation, bringing additional environmental and health benefits.
 

1. Biocarbon sequestration (Biological Carbon Sequestration):
Afforestation and reforestation: By planting trees and restoring forests, plants can absorb atmospheric CO ₂ during growth and store it in biomass and soil.

Soil carbon sequestration: Increase soil organic carbon content and increase soil carbon storage capacity by changing agricultural and land management practices (e. g., reducing farming, planting cover crops, and increasing the use of organic fertilizers).
 

2. Direct air capture (Direct Air Capture, DAC):

Chemisorption method: use a chemical adsorbent (such as sodium hydroxide or amine-based material) to capture the CO ₂ in the atmosphere, and then release and store the captured CO ₂ through heating.

Physical adsorption method: using physical adsorption materials (such as zeolite or activated carbon) to capture and release CO ₂.
 

3. Carbon mineralization (Carbon Mineralization):

Natural mineralization: using calcium and magnesium-containing minerals (such as olivine and seropentine) to react with CO ₂ to generate stable carbonate minerals to permanently fix CO ₂.

Enhanced mineralization: Accelerate the mineralization process by crushing and dispersing minerals and increasing the contact area with its CO ₂ in the atmosphere.
 

4. Biochar (Biochar):

Biochar production: generate biochar by pyrolysis of biomass (such as wood, crop residue) and bury it in the soil. Biochar is highly stable and is capable of storing carbon in the soil for hundreds to thousands of years.
 

5. Marine carbon sequestration (Ocean-Based Carbon Sequestration):

Seaweed farming: grow and breed large-scale seaweed, which absorb CO ₂ during growth, and some of the seaweed can be harvested and used for the production of biofuels or other products.

Marine fertilization: Carbon sequestration is achieved by adding nutrients (such as iron) to the ocean to encourage phytoplankton growth to absorb CO ₂ and settle down to the sea floor after death.
 

6. Carbon capture and storage (Carbon Capture and Storage, CCS):

Industrial emission capture: install capture equipment in industrial emission sources (such as power plants and steel plants), capture and compress the emission CO ₂, and then transported to underground geological repository by pipeline or other means for long-term storage.
 

7. Enhance oil and gas recovery (Enhanced Oil Recovery, EOR):

CO ₂ injection: inject CO ₂ into depleted or depleted oil or gas fields to improve oil and gas recovery, while storing CO ₂ in underground rock formations.
