Introduction

Biomass is biological material derived from living, or

recently living organisms .In the context of biomass for

energy this is often used to mean plant based material, but

biomass can equally apply to both animal and vegetable

derived material.

Chemical composition

Biomass is carbon based and is composed of a mixture of

organic modules containing Hydrogen, usually including

atoms of Oxygen, often Nitrogen and also small quantities

of other atoms including alkali, alkaline earth and heavy

metals. The combustible gas comprises mainly of carbon

monoxide (18-22%), hydrogen (15-20%), methane (1-5%),

carbon dioxide (10-12%) and nitrogen (45-55%).

Categories of Bio mass materials- There are five basic categories of Bio mass material: 

•Virgin wood- From Forestry arboricultural activities or from wood

processing.

•Energy crops-High yield crops grown specifically for energy

applications.

•Agricultural residues-Residues from agriculture harvesting or

processing.

•Food waste-From food and drink manufacture, preparation and

processing, and post-consumer waste.

•Industrial waste and co-products-From manufacturing and

industrial processes

. Need for biomass power in India

• More than 70% of India’s population depends on biomass and

about 32% of the total primary energy use in the country

mainly in rural areas is still derived from biomass. Biomass

gasification based power production, is relevant today

especially in the Indian context.

• In India more than 2000 gasifiers are estimated to have been

established with a capacity in excess of 22 MW and a number

of villages have been electrified  with biomass gasifier based

generators.

Indian Power production Scenario•The average electricity consumption in India is still among the lowest in the world at just 630 kWh per person per year, but this is expected to grow to 1000 kWh in the near future. Some of the highlights of the current power production status in india:-

•India’s current installed capacity (end of 2010): 1,70,229 MW, from all sources•Power generation capacity is mainly based on thermal and hydro, with about 11% from renewable energy.•Electricity demand is expected to rise by 7.4% a year during the next quarter of a century.

Total Installed Capacity of Renewable Power Sources•As of Feb 2011, India has over 18.3 GW of installed renewable energy capacity. Wind represents about 13 GW, small hydro represents 2.8 GW, and the majority of the remainder is from biomass installations

Projected biomass demandIn India, the biomass demand for fuelwood, industrial wood and sawnwood in 2000 was 226 Mt, of which fuelwood accounted for 86.9 percent , industrial wood 7.68 percent and sawnwood, 5.4 percent. It is projected that the biomass demand will increase to 290 Mt by 2010, fuelwood accounting for 241 Mt; industrial wood, 26 Mt and sawnwood, 23 Mt. The sawnwood demand is projected to nearly double in 15 years.

However, a large percentage of this biomass utilized is used as fodder for livestock and for rural energy needs.  As shown in the graph below, only around 20% of the biomass is potentially utilized by the industrial and commercial sector.

16

The main objectives of the Biomass Energy

To encourage the deployment of biomass energy systems in industry for meeting thermal and electrical energy requirements.

To promote decentralized / distributed power generation through supply of surplus power to the grid. To conserve the use of fossil fuels for captive requirements in industry. To bring about reduction in greenhouse gas emissions in industry. To create awareness about the potential and benefits of alternative modes of energy generation in industry.

17

Barriers to accelerated Biomass power Development.

The following specific barriers to development of biomass power projects

have been identified-

•Absence of Effective Institutional and Financing Mechanism.

•Lack of Adequate Policy Framework.

•Lack of Effective Regulatory Framework.

• Lack of Technical capacity

•Absence of Effective Information Dissemination.

•Limited Successful Commercial Demonstration model Experience.

18

Policy and Regulatory Frame work

•In 1981, india created a government commission with overall

responsibility for developing renewable energy and a separate

department of Non-conventional Energy sources.

•The Ministry of new and Renewable Energy issued the Renewable

Energy power Purchase Guidelines to all states in 1993.

•The Electricity Act of 2003 guaranteed interconnection for renewable

energy sources.

•Almost all states have implemented some form of preferential tariffs

for renewable energy generation.

•These measures have been strengthened by the National electricity

policy 2005.the Tariff policy of 2006, the Rural electrification policy

2006 and the integrated energy policy report of Planning commission

of india in 2006

•Today India’s power market mostly comprises regulated prices with a

few states introducing open bidding on electricity through ten to

fifteen year power purchase agreements.

Economical and Technological Aspects of Bio Energy Production

• Biogas gasification works well for small scale power production, upto a maximum capacity of 2 MW. Combustion, on the other hand, works well at MW scales.• The capital cost per MW for a biomass gasification plant is about Rs 5.5 crores, while the operational expenses (excluding the cost of biomass) are about 0.75 Rs per kWh. The levelized cost of power from biomass gasification will be in the range of Rs 2.25-4/kWh, depending mainly on the cost of the biomass.• Under optimal conditions, biomass gasification based power production presents a good business opportunity with attractive IRRs (over 25%) and payback periods (fewer than 3 years). •It can operate at small scales (10-25 kW) as well as medium scale (upto 2 MW).•India has an estimated potential of over 30,000 MW of power from biomass, but less than 2500 MW has been exploited. Thus, over 90% of capacity from potential still exists.

As per The India Biomass Gasification Report-May 2011

Managerial concerns observations and Suggestions • Compared to coal, and indeed compared to almost any other combustion fuel, biomass is expensive to handle and move, and cost of transportation looms large in assessments of financial viability.• The distributed nature of the wood fuel source and the relatively high cost of wood movement suggest that in general, wood-chip burning power plants will be relatively small and dispersed. •Yet the other major influence on plant size is economies of scale in plant operation: larger plants generally use less labor, operate at higher efficiencies, and have lower costs per kWh generated than smaller plants.

The implications for rural development could be far reaching if bioenergy can supply a significant proportion of this modern energy requirements. Many commercial possibilities could be created with many social and economic benefits. In addition, there is a considerable potential for improving the environment.

Thus replacing fossil-derived energy with biomass can reduce greenhouse gases and mitigate global climate change. 

24

CONCLUSION• Bioenergy should not be regarded as the panacea for solving agricultural and energy problems in the rural areas, but as an activity that can play a significant role in improving agricultural productivity, energy supply, the environment and sustainability. Its final contribution will depend on a combination of social, economic, environmental, energy and technological factors.

•The potential role in bioenergy production should receive greater recognition, together with the need for positive political encouragement, and socio-cultural adaptations.

•The scenarios considered for estimating the biomass potential as per the above study are incremental biomass demand, sustainable biomass demand and the full biomass demand. Under these scenarios, two situations namely no increase in cropland by 2010 and increase in cropland by 10%..

•Annually 62–310 Mt of wood could be generated from the surplus land, after meeting all the requirements of biomass, such as domestic fuelwood, industrial wood and sawnwood, with an investment of Rs168–780 billion
