Article Selection My group decides to do several research and reads some reliable articles related to Bio-energy with carbon capture and storage (BECCS), which is new technology that can significantly reduces the carbon dioxide emission.

Post-combustion technique:

During the process, CO2 is separated from the other gases in the flue gas stream after the biomass fuel is burnt and undergo separation process. Because it has the ability to be retrofitted to some existing power plants such as steam boilers or other newly built power stations, post-combustion technology is considered as a better option than pre-combustion technology. According to the factsheets U.S. CONSUMPTION OF BIOENERGY WITH CARBON CAPTURE AND STORAGE released in March 2018, the efficiency of post-combustion technology is expected to be 95% while pre-combustion and oxy-combustion capture CO2 at an efficient rate of 85% and 87.5% respectively. Development for current post-combustion technologies has not been entirely done due to several problems. One of the major concerns using this technology to capture carbon dioxide is the parasitic energy consumption. If the capacity of the unit is designed to be small, the heat loss to the surrounding is great enough to cause to many negative consequences. Another challenge of post-combustion carbon capture is how to deal with the the mixture’s components in the flue gases from initial biomass materials after combustion. The mixture consists a high amount of alkali metals, halogens, acidic elements, and transition metals which might have negative impacts on the efficiency of the process. Thus, the choice of specific solvents and how to manage the solvent process should be carefully designed and operated.

Evaluate an article: "Carbon Capture with Storage: A New Frontier for Biomass?" http://biomassmagazine.com/articles/15217/carbon-capture-with-storage-a-new-frontier-for-biomass

The article overviews how the government makes effort to pass many laws that give the subsidies for renewable energy technology companies. A company can earn up to $50 per ton of CO2 emission captured from burning fossil fuel. Because of new federal and state laws on taxes and grants, the renewable energy technology companies have an incentive to do research and development on alternative energy which are eco-friendly. Thus, the investors tend to look for future investment opportunities in new energy areas. The article is related to BECCS topic; therefore, it helps to strengthen the ideas and points in BECCS topics.
