Using waste biomass for energy presents several challenges, including high costs, logistical difficulties, environmental concerns, and technical limitations. These challenges stem from the need for large areas for plant growth, the complexity of converting biomass into usable energy, storage and maintenance issues, and the environmental impact of biomass energy production. Additionally, the reliance on non-renewable resources for hydrogen production and the health risks associated with biomass combustion further complicate its use as a sustainable energy source.

Key Points Explained:

1. High Costs and Low Productivity

   • Constructing biomass plants requires significant investment, particularly due to the need for large areas of land for plant growth, which is scarce in urban regions.
   • Biomass energy production is less productive compared to other energy sources, making it less economically viable in some cases.

2. Complex Conversion Processes

   • Converting lignocellulosic biomass into high-value chemicals or energy involves technical challenges, such as achieving high selectivity and performance at lower costs.
   • Producing hydrogen from biomass often relies on steam reforming of natural gas, a non-renewable fossil fuel, which undermines the sustainability of the process.

3. Storage and Maintenance Challenges

   • Biomass storage requires high maintenance to prevent decay or energy loss, and constructing storage facilities is costly.
   • Harvesting, storing, and exporting biomass often demand additional energy inputs, such as solar power, which increases the overall energy footprint.

4. Environmental and Health Concerns

   • Biomass energy production emits smoke and gases, which can cause health issues for nearby populations.
   • Inefficient combustion methods, such as open fires, can damage land, emit unclean air, and contribute to deforestation, desertification, and land degradation.
   • The use of moist wood as fuel increases smoke emissions, exacerbating air pollution and health risks.

5. Logistical and Social Challenges

   • Collecting suitable biomass resources often requires significant time and effort, placing an additional workload on communities.
   • The process of transporting and managing biomass can be logistically complex and energy-intensive.

In summary, while waste biomass has potential as a renewable energy source, its utilization is hindered by economic, technical, environmental, and social challenges. Addressing these issues is crucial for making biomass energy a more viable and sustainable option.
