Carbon capture and storage (CCS)

Question

Answered

The company you work for is planning to build a new carbon capture and storage facility in Victoria to offset the carbon produced by their existing coal-fired power plants. There has been considerable opposition to these plans in the media. Your task is to write a media release defending the company’s position against attacks by 1. Supporters of renewable energy solutions 2. Supporters of the existing coal-fired power plant system, who disagree with the need to conduct CCS. 3. Supporters of “human” solutions such as appeals to the public to turn down air-conditioner settings Your article should acknowledge the concerns of each group, and respectfully explain why your plan is the best option. To inform and persuade your audience. Argue your point of view clearly but respectfully. You will have to acknowledge the concerns, fears and values of your readers and use logical argument to convince them rather than alienate them by telling them they are simply wrong. Marks will be awarded for achieving your purpose through successfully using essay structure, style, and language. Keep strictly to the style guidelines below. Quote: “When something is important enough, you do it even if the odds are not in you favour.” (Elon Musk) Intro: – Carbon capture and storage (CCS) is a counterfeit version of carbon sequestration, which is the process that plants carry out during photosynthesis. – CCS is a latest technology used to for the benefits of the environment – It helps to prevent large amount of CO2 from being released into the atmosphere due to the power generations and other industries. The industries that uses fossil fuel as their raw products produce large quantities of CO2 which contributes into climate change – From Australian Bureau of Statistics of 2009, Victoria is accountable for 21% of Australia’s total net emissions. – The most significant greenhouse gas that contributes more than 80% of the total Victorian emissions in 2009 is carbon dioxide (CO2) – Basically, there are three methods to capture the carbon dioxide from a power plant: a) precombustion, which is before the fuel is burned b) postcombustion, which is after the fuel is burned c) oxyfuel, which is by burning the fuel in more oxygen and storing all the byproduct as a result – The carbon dioxide is stored under Earth’s surface. In other terms, geo-sequestration. Besides that, CO2 can also be stored in the oceans or reacting it with minerals, but this method requires a lot of energy. Advantages: – CCS is applied to a modern conventional power plants as it helps to reduce CO2 emission to the atmosphere by about 80 -90 % compared to a plant without CCS. – The solvents used to capture CO2 from the flue gases with excrete some nitrogen oxides and sulphur oxides. Disadvantages: – Increases the emissions of acid gas pollutants significantly – The energy needed to capture, and compress CO2 is high and would increase the fuel needs of a coal- fired plants with CCS by 25-40 % – These and other system costs are estimated to increase the cost of energy from a new power plant with CCS by 21- 90 % – Water consumption, however, may be an issue for carbon capture systems which rely on solvents to remove CO2 from flue gases – This increase in water consumption may make these systems less suited to dry regions. Environmental Impacts Due to Carbon Capture: – In ocean storage, co2 reacts with water to form acid, so the oceans could become significantly more acidic – Another difficulty is that co2 would also eventually return to the atmosphere – In addition to the global climate change impact of co2 returning to the atmosphere, leakage pose local risks to health and ecosystems. – For storage sites under water, there are concerns about chronic expore of marine ecosystems to raised co2 levels, such as might occur near injection sites. – For co2 storage sites on land, there are concerns that large scale leakage could harm people and wildlife in the immediate vicinity. http://debatepedia.idebate.org/en/index.php/Debate:_Carbon_capture_and_storage https://www.sciencedirect.com/science/article/pii/S1462901116300284 http://climatescience.oxfordre.com/view/10.1093/acrefore/9780190228620.001.0001/acrefore-9780190228620-e-444
