Bio - Mass Energy

Bio-Mass Energy:-

Biomass is organic material made from plants and animals. Biomass contains stored energy from the sun. Plants absorb the sun's energy in a process called photosynthesis.Burning biomass is not the only way to release its energy. Biomass can be converted to other usable forms of energy like methane gas or transportation fuels like ethanol and biodiesel. Methane gas is the main ingredient of natural gas. Smelly stuff, like rotting garbage, and agricultural and human waste, release methane gas - also called "landfill gas" or "biogas." Crops like corn and sugar cane can be fermented to produce the transportation fuel, ethanol. Biodiesel, another transportation fuel, can be produced from left-over food products like vegetable oils and animal fats.


Bio-Mass Project Barriers:-
Despite their technical feasibility and multiple benefits, bioenergy technologies have not spread in India, apart from a few isolated demonstration projects. Bioenergy technologies have so far failed to make an impact on the rural energy scene due to a number of technical, market, information, financial and institutional barriers.

Technical Barriers: As a result of the limited success and scale of previous bioenergy demonstration initiatives, the operational feasibility and financial viability of an integrated bioenergy package has yet to be proven. This is a key barrier resulting in high-perceived risks attributed to the technology by the manufacturers, entrepreneurs, and end-users. In addition, the lack of standardization has led to poor reliability of these bioenergy packages. Limited availability of sustainable biomass is yet another barrier to the use of gasifiers.

Institutional Barriers: The insufficient capacity of the village-level institutions for implementation of bioenergy services package in rural areas also serves as a significant barrier. There are also institutionalrelated financing barriers (e.g., the absence or lack of micro-credit facilities at the target users' level).

Information Barriers: The lack of awareness and information on viable technological configurations act as a barrier to promotion of these technologies.
Financial Barriers: The high perceived technical and institutional risks act as major barriers to investments in bioenergy. Furthermore, the lack of capital for investments and the risk involved has acted as a de-motivating factor for private enterprises.

Market barriers: Bioenergy technologies, in general, have to compete with the conventional sources of energy either with subsidized electricity and fossil fuels (kerosene) options or freely accessible fuelwood and biomass residues. In such a situation, absence of a level playing field acts as a key barrier to market penetration.
