Access to affordable and reliable energy remains a persistent challenge in rural areas of developing countries, where households continue to depend on traditional fuels such as firewood and charcoal. This reliance contributes to deforestation, indoor air pollution, and household energy insecurity. Biogas technology offers a renewable and sustainable alternative capable of addressing these environmental and socio-economic challenges. However, widespread adoption has been constrained by high upfront installation costs, inadequate financial support systems, and limited access to credit facilities. This study reviews existing financing models that have been applied globally and in South Africa to promote the uptake of biogas technology in rural communities. Using a literature-based analytical approach, the paper identifies and evaluates key financing mechanisms, including government subsidies and grants, microfinance and community-based lending, public-private partnerships, carbon credit schemes, and international development assistance. The analysis reveals that while government subsidies and donor support play a vital role in initiating projects, long-term sustainability depends on integrating market-based solutions such as microfinance, carbon trading, and private-sector participation. Findings also show that community engagement and cost-sharing models enhance ownership and maintenance of biogas systems, reducing dependency on external funding. The paper concludes that no single financing mechanism can ensure widespread adoption. Instead, a hybrid approach that combines policy incentives, capacity building, and innovative financing structures is necessary to overcome economic barriers. Strengthening financial inclusion and promoting partnerships across public, private, and community levels are critical to unlocking the potential of biogas technology for sustainable rural development.
