This high concentration means that when it undergoes combustion, a substantial amount of CO2 is generated per unit of energy released. Examples include varying types, such as anthracite, bituminous, subbituminous, and lignite, each with differing carbon contents. This directly influences the amount of CO2 emitted during combustion. The implication is a strong contribution to greenhouse gas emissions.
- Inefficient Combustion
Complete oxidation of the carbon within a fuel results in the formation of CO2. However, incomplete combustion processes can lead to the production of carbon monoxide (CO), a toxic gas, and unburnt hydrocarbons. Examples can include older, less efficient power plants where complete combustion is not always achieved. The implication is exacerbated pollution through the generation of both CO2 and other harmful pollutants.
- Energy Density vs. Emissions Ratio
Despite possessing relatively high energy density, its carbon intensity means that other energy sources may offer a better balance between energy output and environmental impact. Examples of comparison include natural gas, which has a lower carbon-to-hydrogen ratio, and renewable energy sources, which have negligible direct carbon emissions during operation. This comparative disadvantage poses a challenge for achieving climate targets.
- Contribution to Global Warming
The cumulative effect of burning it worldwide has made it a major contributor to the increase in atmospheric CO2 concentrations. Examples of these effects include rising global temperatures, sea-level rise, and ocean acidification. The implication is an amplified risk of extreme weather events and long-term ecological damage.
The multifaceted nature of this carbon intensity, from its fundamental composition to its global impact, underscores the challenges of continuing its widespread use.
