BIOENERGY

AND

SUSTAINABILITY

2012

Biomass materials meet myriad human needs including

energy. Sources of biomass energy are trees, crops and

animal waste. Thermo and Bio Conversion technologies

would make efficient bioenergy end use available.

With rapid increase in fossil fuel use, the share of

biomass in total energy declined steadily through

substitution by coal in the nineteenth century and later by

refined oil and gas during the twentieth century.

2

Oil & Gas: The twentieth century ushered in oil which

developed into one of the most vibrant global energy for

agriculture, transport and industries including electric power.

One hundred years later, this industry has reached its zenith

with the panorama of entering its twilight years in the second

half of this twenty-first century. How far in the future can the

happening of this event be deferred depends on how much

we can decelerate a runaway demand and how

expeditiously we can implement specialized renewable

technologies. These measures will give us more breathing

space to develop alternate energy forms, non hydrocarbon

fuels like biomass.

With a rapidly growing economy and rising population,

India is the fifth largest and one of the fastest growing

petroleum oil consumers in the world. With limited

domestic crude oil reserves, India meets over 72 per cent

of its crude oil and petroleum products (diesel, aviation

fuel, etc.) requirement through imports. Energy demand in

the transport sector is growing relatively high due to the

growing economy and rising private vehicle ownership,

particularly four-wheelers. Due to rising oil consumption

and relatively flat domestic production, India is increasingly

dependent on imports to meet its petroleum demand. 4

• What is bioenergy?

– Energy from trees, plants, crops

or from human, animal, municipal

and industrial wastes – Woody and

Non Woody Biomass.

• Woody - derived from forests,

plantations and forestry residues

• Non Woody - comprises agricultural

and agro industrial residues, algae,

and animal, municipal and industrial

wastes.

What is Sustainability?

Bioenergy- In a social, economic, legal

and political setting 9

Power, Lighting, Heating, Operation of Kilns,

Transportation, Milling, Motor Usages, Cooking.

• Solid biomass combustion and gasification for

electricity

• Slurry biomethanation for electricity and

cooking energy (gas)

• Efficient wood-burning devices for cooking

• Liquid biofuels for local usages and

transportation 10

MATURE TECHNOLOGIES:

Biofuel stoves for home & institutional cooking

Biogas digesters for cooking & lighting

Briquetting for producing ‘biocoke’ from

particulate agro residues

Thermal gasification system to generate producer

gas for diesel substitution in stationary engines

for water pumping and rural industry.

What are the connections between

Bioenergy and Sustainability in India?

To meet sustainability goals – social,

environmental domains

GOALS OF BIOENERGY TECHNOLOGIES

In India, policies aim to promote modernization

and commercialization of biomass production,

combustion, densification, and electricity

generation.

A long-term techno-economic analysis using the

MARKAL model shows that biomass electricity

technologies have significant potential to penetrate

Indian market under a fair competition with the

fossil technologies. Under an optimal greenhouse

gas mitigation regime, biomass electricity

penetration can be reached in next thirty years. 13

14

Myriad economic, social, technological and institutional

barriers remain to be overcome. The future prospects

of biomass technologies depend considerably on

removing these barriers. The key issue before

the Indian policy makers is to develop the market for

biomass energy services by ensuring reliable and

enhanced biomass supply, removing the tariff

distortions favouring fossil fuels and producing energy

services reliably with modern biomass technologies at

competitive cost.

RESOURCES FOR BIOFUELS IN INDIA

India's biofuel strategy continues to focus on use of

non-food sources for producton of biofuels: sugar

molasses for production of ethanol for blending with

gasoline, and non-edible oilseeds for production of

biodiesel for blending with petro-diesel.

The government's current target of five per cent

blending of ethanol with petrol has been partially

successful in years of surplus sugar production, but

falters when sugar production declines.

15

• The cornerstone of India's energy security

strategy is to focus efforts toward energy self-reliance

and developing renewable energy options like biofuels

vis-à-vis fossil fuels.

• Adoption of environmentally friendly biofuels to

meet improved vehicle emission norms.

• Developing an alternative usage for crops like

sugarcane and its byproducts as feedstock for biofuels

to support farm income.

• Improve utilization of wastelands and other

unproductive land for cultivation of biofuel feed stock.

• Enhance rural employment and livelihood

opportunities by promoting production and marketing of

biofuel feed stocks

POTENTIAL SOURCES FOR BIOMASS

o Agricultural Residues

Forest Waste - forest, forest tree

twigs,

Crops – Rice, Maize, Cotton,

Sugarcane

Dung – Cattle, Buffalo - cattle dung,

leaf litter

Oil bearing seeds, crops - Jatropha

curcas, Neem, Mahua, Wild Species,

Sweet Sorghum, Rice Bran, Neem,

Sal, Karanja

Energy forms which are available –

– gaseous (biogas, producer gas)

– liquid (ethanol, methanol, biofuels)

– solid (briquette) fuels

Penetration of bioenergy technologies has been

marginal in comparison to the target inspite of

large number of programmes

Lignocellulosic ethanol technologies by biochemical

conversion using enzymes are the focus of a

considerable amount of research, notably in the

United States. Thermochemical conversion, by

gasification and the Fischer Tropsch synthesis of

the gases into petroleum substitutes, is also under

evaluation at a demonstration scale. There is no

clear consensus about when lignocellulosic

technologies will be commercially competitive.

26

The National Programme for Improved Cook stoves

(NPIC) was launched to disseminate mud based improved

cook stoves, equipped with chimneys, and portable metallic

stoves to increase the fuel use efficiency and to reduce

indoor air pollution.

ƒThe National Project on Biogas Development (NPBD),

to set up family type biogas plants.

ƒThe Village Energy Security Programme (VESP) was

started by the MNRE with an objective to provide total

energy requirement of villages_ lighting, cooking, and

motive power with the involvement of local community.

27

Biomass based power systems come under the

purview of the Electricity Act. Further, the Rural

Electrification Policy (2006), National

Electricity Policy (2005) and the Integrated Energy

Policy (2005) provided the required enabling

environment for the promotion of electrification to

the entire country. The National Policy on Biofuels

was approved by the Government of India (GOI)

on December 24, 2009.

PRACTICAL CONSIDERATIONS

alternative use of biomass as fodder or

industrial raw material

collection efficiency

actual availability of so-called waste

lands, forest lands and other types of

lands

availability of water, geographical and

weather conditions

28

29

The most vital issue for biomass energy in India is

the development of market for biomass

energy services.

Two broad responses to this are:

i) ensuring reliable and enhanced biomass

supply, and

ii) provide energy services reliably with biomass

technologies at competitive cost.
