Environmentally Friendly Energy Future in Australia Essay

2569 Words 11 Pages
Introduction
The development of industrialisation and advanced technology has played an important role in increasing energy consumption in the world. This increasing use of energy pattern has also brought a number of both environmental and human health problems such as greenhouse emissions. Despite this fact, most of the world’s energy is produced using fossil fuels such as coal, oil, and gas. For example, in 2008, Australian energy production was 302.13 million tonnes of equivalent oils (Mtoe) while the consumption of energy was 240.40 terawatt hours (TWh) and these amounts of energy consumption and production caused 397.54 million tonnes of carbon dioxide (Mt CO2) emissions to the world’s atmosphere (Drachman & Richard, 2010, p. 48).

Thus, clean coal technologies such as either called carbon capture and storage or geosequestration can significantly reduce environmental problems such as carbon dioxide emissions to the atmosphere and effectively produce energy without future damage to the environment in Australia. This essay will explain geosequestration technology, compare with nuclear or renewable energy sources, identify the future challenges of geosequestration, and explain how it can meet the sustainable environmental policy in Australia.
CO2 Capture and Storage (Geosequestration)
Currently, this technology is the most reliable technology in terms of sustainable environmental policy and economic factors. This technology has demonstrated effectively in the industry of oil and natural gas to enhance the extraction of oil and gas. Furthermore, geosequestration technology can be defined as the capture, transport, injection, and geological storage of carbon dioxide (CO2). Firstly, CO2 needs to be separated and captured to the CO2 compression unit, where CO2 emission changes into liquid condition, from the source such as coal-fired power plants or industrial facilities. After that, the captured CO2 is transported to a selected geological site by mostly using pipelines and injected to deep underground into a geological reservoir where CO2 will be stored for a long time and the depth of underground is usually at least one kilometre. Finally, there must have regular monitoring to ensure the…
