The main attraction of BECCS lies in its ability to drive negative CO2 emissions. Capturing carbon dioxide from bioenergy sources effectively removes CO2 from the atmosphere. Bioenergy is obtained from biomass which is a renewable energy source of Power to Choose Texas and serves as carbon dioxide during its growth. During the production process, burning or converting biomass releases CO2 back into the atmosphere.
Carbon Capture and Storage (CSS)
Carbon Capture and Storage (CCS) technology is used to prevent the release of CO2 into the atmosphere and transport it to landfill or solid waste storage sites. The system thus results in zero CO2 emissions, although this can change positively or negatively depending on the carbon emissions associated with the growth, transport, and transformation of biomass, see below the environment. Not only CO2 from biomass comes from the biomass power plant, but also during the production of the pulp used in paper making and the production of biofuels such as biogas and bioethanol. BECCS technology can also be used in industrial processes such as cement production. BECCS technology captures carbon dioxide in a sustainable landscape, where a plant only stores its carbon during its lifetime. The IPCC special report on CCS technology predicts that more than 99% of the carbon dioxide stored in the atmosphere will remain in place for more than 1000 years. Although other forms of carbon emissions such as oceans, trees, and soil may involve the risk of negative feedback to high temperatures, BECCS technology can provide better longevity by storing CO2 and landscaping.
Industrial processes have released so much CO2 that it is absorbed by water sources such as plants and soil to meet the low-carbon targets. In addition to the production currently collected, there will be other large crops during this century, even under the most demanding climate conditions. Therefore, BECCS is recommended as a technology to change production behavior and create a global system of poor air quality. This means that it is not only zero, but negative, so that not only the atmosphere, but the total amount of CO2 in the atmosphere will decrease.
Applications:
I Ethanol production
The production of biomass such as sugar cane, wheat, or corn emits CO2 as a by-product.
II Pulp and Paper Mills/Cement Manufacturing
- CO2 is produced in the recovery boiler.
- CO2 is produced in lime kilns, as during the production of cement. For gasification technology, CO2 is produced during the gasification of black liquor and biomass such as tree bark and wood.
- A large amount of CO2 is also released from the combustion of syngas, a product of gasification, in the combined cycle. biogas production
- In the biogas upgrading process, CO2 is separated from methane to produce high-pressure gas.
III Power plant
Burning biomass or biofuel with steam or gas produces CO2 as a by-product.
IV Firewood
Burning biofuel for heat production releases CO2 as a by-product. District heating is often used.
Cost
The IPCC said BECCS price estimates range from $60 to $250 per tonne of CO2.
Research estimates that the electrochemical method that combines salt water electrolysis with climate recovery of electricity obtained from non-fossil fuels can, on average, increase both energy production by more than 50 times CO2 removal compared to BECCS, the same or even lower. notification. cost, but further research is needed to develop such methods.
