Clean Coal Technologies

Sustainable Energy Solutions for Africa

Introduction

Energy is vital for economic growth and industrial transformation, especially in regions like Africa, where coal deposits provide a potential source for affordable electricity. However, traditional coal combustion produces high emissions including carbon dioxide (CO₂), nitrogen oxides (NOₓ), and sulfur dioxide (SO₂).

Clean coal technologies (CCTs) aim to improve combustion efficiency and minimize these pollutants, promoting access to cleaner and sustainable energy. This page highlights key CCTs that can help address Africa’s electricity gap, where over 43% of the population lacks access.
