Burning fossil fuels (coal, natural gas and oil) for energy purposes releases a gas called carbon dioxide (C02)into the atmosphere. The ever-increasing levels of Co2 in the atmosphere contribute to global warming and thus harm the environment. In order to combat global warming, scientists have proposed capturing CO2 from industrial facilities that use fossil fuels and storing it underground. The captured Co2 would be transported to storage sites and injected into deep underground rocks. However, there are several significant challenges that make it difficult to store CO2 underground.
Storage
First, there is the question of whether locations proposed for storing Co2 have enough space. The burning of fossil fuels around the world releases billions of tons of Co2 into the atmosphere annually. In order to make a considerable difference in combating global warming, most of the released Co2 would need to be captured and stored underground. It is not clear whether underground sites suitable for CO2 storage have enough space.
Health Risks
Second, if C02 escapes from underground storage sites, it can pose risks to human health. CO2 leaks may occur if, for example, unforeseen natural processes or forces create cracks in the ground above the storage site. Although the normal atmospheric levels of Co2 are harmless, high concentrations of Co2 may be unsafe, causing headaches, tiredness. and possibly even death.
High Costs
Finally, a wide range of costs are associated with the process of storing CO2 underground. First, new technologies for capturing and storing C02 that currently do not exist will have to be created. In addition, new infrastructure, such as pipelines transporting Co2 from industrial facilities to storage sites. will have to be built. All of these requirements will likely result in very high costs for constructing and operating CO2 storage systems.
The passage discusses the possibility of storing CO2 which makes a significant contribution to global warming but puts forward several challenges that make the process not practical. Whereas, the speaker comes up with solutions for each challenge.
First and foremost, The article explicitly states that finding such locations for storing CO2 which needs a large space difficult, On the other hand, the professor points out the fact that Gases including CO2 when are exposed to high pressure and temperature are transformed into liquid of which requires smaller space to storm. Therefore, finding a suitable location is out of the question.
Secondly, The writer presents the health risks that CO2 will expose if they are released from underground storage. The lecture, Conversely, Clears out that Some credible research has shown that CO2 stays close to the ground thereby people will not be affected unless they sleep on the ground, for example. moreover, the amount of CO2 could be monitored, hence alarming people nearby.
Last but not least, The author contends that storing CO2 involves both new technology and infrastructure which leads to making the process costly. In stark contrast, the speaker calls this contention into question. He refers to deep underground rocks containing methane, a precious gas that could be extracted by pulling CO2. As a result, it makes up for the expensive process of storing CO2.
