This projects show a good potential for success in using carbon geosequestration as a process for checking carbon emissions (Goulder. and Mathai, 38). High costs pose a great challenge to carbon sequestration. It is estimated that a ton of carbon dioxide costs more than 30 dollars to sequestrate (Grübler, Nakicenovic, and Nordhaus, eds. There are great technical difficulties in reducing these costs given current levels of technology. There is technological knowhow and mechanisms of separating carbon dioxide and hydrogen. However, the capital and costs of operations are quite high. This is mainly because these technologies are preferably applied in fossil fuel combustion.
There are is need for more research and development in this field in order to reduce the costs of carbon sequestration. Costs of mitigating leakages of carbon dioxide form the ground are also very high. If this gas’ concentration is stabilized at double preindustrial levels, a 1% leakage is tantamount to around 850 billion dollars annually up to 2095 (Kauppi 98). therefore, a leakage of around 1 percent or less poses an intolerable transfer of cost to future generations. However, there is no empirical evidence that 1 % or less carbon dioxide is leaked from reservoirs.
This further increases the uncertainty of costs meaning that the economic burden of carbon sequestration might even be higher than anticipated (Kauppi 105). There are three main problems of carbon sequestration. These are; Storage security, heightened energy consumption and lack of large-scale practicality. Storage security involves the potential danger of storing carbon dioxide at very high pressure levels. Any technology used in injecting carbon dioxide is susceptible to human errors. Such an error would cause loses in property worth millions and thousands of mortalities.
A release of the gas back into the atmosphere would be disastrous like the Cameroon’s Lake Nyos disaster. There is high energy consumption associated with carbon sequestration. A coal burning is likely to require an amount as high as 15% of the energy it creates to inject carbon dioxide to the ground Here, it is assumed that the gas in=s injected I the ground right below the coal mine. However, if instances occur where the gas would need to be transported in order for it to be
