Burkina Faso's power generation emits 0.663 kg CO2/kWh, highlighting the impact of fuel choice on carbon footprint.
Category: Resource Management · Effect: Strong effect · Year: 2023
Specific CO2 emission factors for Heavy Fuel Oil and Distillate Diesel Oil in Burkina Faso's power generation are significantly higher than default IPCC values, leading to a more accurate, and higher, estimate of national emissions.
Design Takeaway
When designing energy systems or products, use precise, context-specific emission factor data rather than broad averages, and actively advocate for and integrate renewable energy solutions.
Why It Matters
Understanding precise emission factors is crucial for accurate environmental reporting and for developing targeted strategies to mitigate climate change. This research provides a localized data point that can inform policy decisions and drive the adoption of cleaner energy sources.
Key Finding
Burkina Faso's power generation, particularly from fossil fuels like HFO and DDO, has specific CO2 emission factors that are higher than general estimates. Incorporating renewable energy significantly reduces these emissions, with a 14.25% share in 2018 avoiding 16.7% of CO2 emissions.
Key Findings
- CO2 emission factor for HFO combustion: 76,903 kg/TJ
- CO2 emission factor for DDO combustion: 73,525 kg/TJ
- Estimated CO2 emissions from power generation in 2018: ~580 Gg
- CO2 emission factor for thermal power generation: 0.663 kg/kWh
- CO2 emission factor for the electricity generation mix: 0.569 kg/kWh
- 14.25% renewable energy avoided 16.7% of CO2 emissions in 2018
- Increased renewable energy share reduces the electricity production emission factor.
Research Evidence
Aim: What are the specific CO2 emission factors for power generation in Burkina Faso, and how does the integration of renewable energy impact these emissions?
Method: Quantitative Analysis
Procedure: The study analyzed fuel characteristics (molecular composition, density, water content) for Heavy Fuel Oil (HFO) and Distillate Diesel Oil (DDO) used in power generation. Based on this analysis, specific CO2 emission factors were calculated for these fuels and for the overall electricity generation mix. The contribution of renewable energy to CO2 emission reduction was also assessed.
Context: Energy sector, power generation, climate change mitigation, Burkina Faso
Design Principle
Context-specific data leads to more accurate environmental impact assessments and effective mitigation strategies.
How to Apply
When conducting life cycle assessments or environmental impact studies for energy-related projects, research and utilize the most specific emission factor data available for the region and technologies involved.
Limitations
The study focused on 2018 data and specific fuel types; emission factors may vary with changes in fuel quality, technology, and energy mix over time.
Student Guide (IB Design Technology)
Simple Explanation: This study found that the way electricity is made in Burkina Faso creates more CO2 than expected, especially when using certain fuels. Using renewable energy, like solar or wind, helps a lot to lower the amount of CO2 produced.
Why This Matters: Understanding real-world emission factors helps you make better design choices that genuinely reduce environmental harm, rather than relying on general assumptions.
Critical Thinking: How might the adoption of new energy technologies or changes in fuel sourcing in Burkina Faso alter these calculated emission factors in the future?
IA-Ready Paragraph: This research highlights the importance of using localized emission factors, such as the calculated 0.663 kg CO2/kWh for thermal power generation in Burkina Faso, which can differ significantly from generic IPCC default values. The study also quantifies the substantial CO2 reduction achieved through renewable energy integration, demonstrating a clear pathway for mitigating environmental impact in energy systems.
