Impacts of Coal-to-Gas Conversion

Coal-to-gas conversion activities by countries seem to be a good idea for reducing carbon emissions. However, it also has significant environmental, climate, social, and health implications, so governments should carefully consider its pros and cons before implementing such a policy.

For instance, converting coal to gas can reduce carbon dioxide emissions significantly compared to coal alone. This helps with climate change mitigation efforts by decreasing greenhouse gases contributing to global warming. In addition, gas-powered plants are generally more efficient than coal-powered ones, meaning they can produce the same or more energy with fewer resources.

However, converting to gas also poses some drawbacks. First, switching energy sources and building new plants for gas-powered electricity production can be costly. This cost is often passed onto consumers as higher utility bills.

In addition, converting coal to gas can produce byproducts such as carbon monoxide, sulfur dioxide, and nitrogen oxides contributing to air pollution. This could create serious health risks for nearby people, especially those with pre-existing respiratory conditions.

All-in-all, it is crucial that countries consider the environmental, economic, and social impacts of coal-to-gas conversion before making the switch. In some cases, alternative measures such as increased energy efficiency or renewable sources may be more cost-effective and better for human health in the long run.

Specific Case: South Korea

A study by Climate Analytics titled 'Clean power in South Korea' was published in March 2023. The study outlined the main issues in coal-to-gas conversions.

First, the study finds that such conversions pose a climate risk. Switching from coal to gas is likely to increase the country's dependence on natural gas, creating more emissions and thus undermining South Korea's goal of reducing its reliance on fossil fuels. It also entails that it "delays the deployment of zero-emissions electricity generation" needed to achieve a clean power sector.

Second, the study finds that it poses financial risks. Since renewables are outcompeting fossil resources, converting coal to gas could mean South Korea may be locked into costly investments in natural gas-fired infrastructure. One analysis of this activity states that South Korea will have a $60 billion stranded asset (Climate Tracker Initiative, 2020). As the coal-to-gas conversion is an uncompetitive and expensive generation form, it is time to transition to renewables as their cost is plummeting.

Third, according to the Climate Analytics study, coal-to-gas conversion does not align with the 1.5 degrees Centigrade pathway and thus should not be prioritized. Instead, such activities be immediately halted, and transitioning to renewables would be the only reliable pathway to fulfill the country's commitment to the Paris Agreement (2015).

Switching from coal to gas is risky for South Korea's environment, economy, and citizens' health, as it would create more various harmful gas emissions and delay the transition to zero-emissions electricity generation. As demonstrated by specific case studies, coal-to-gas conversion can have serious environmental and health risks. For example, in the United States, the fracking process used to extract natural gas from shale rock has been linked to groundwater contamination and air pollution. In addition, burning natural gas still releases greenhouse gases into the atmosphere, albeit at a lower rate than burning coal. These are just a few examples of the potential impacts of coal-to-gas conversion that should be carefully considered before implementing such policies.

In conclusion, coal-to-gas conversion activities should only be considered when other, more cost-effective alternatives are unavailable. Countries need to weigh the pros and cons carefully before making any decisions on such policies, as the implications of these activities can have wide-ranging effects on the environment, economy, and public health. South Korea is no exception and should consider these considerations when considering such activities.
