Many countries currently rely on coal, oil and natural gas to meet

their energy needs.

Depending on fossil fuels on a long term basis is risky as they

will eventually run out.

Fossil fuels cause air and water pollution, including production of

greenhouse gases that could increase global

warming.

The need of the hour is to use alternatives to

fossil fuels such as bio energy.

ESSENTIAL COMPONENT OF BIOENERGY -- BIOMASS

BIOMASS: Material that is derived from living or recently livingbiological organisms. In the energy context it is often used to refer to

plant material, however by-products and waste from livestock

farming, food processing and preparation and domestic organic

waste, can all form sources of biomass. [2]

Biomass is ranked fourth after coal, oil and natural gas with regard to

natural source of energies in the world.

Chemical conversion

Different chemical processes are involved

in the conversion of biomass.

Bio-chemical conversion

Fermentation /Anaerobic digestion of organic matter to produce

biogas.

Example: production of biogas from animal/human excreta.

Enzymes from micro-organisms are used in the breakdown of

biomass.

Example: cellulase and hemicellulase

PRODUCTION OF BIOGAS

Fig.1


12/22

Bioethanol is a liquid form of biofuel.

Bioethanol (bioalcohol) is produced by fermenting simple

sugar components of biomass.

Sources: corn, sugarcane and starch crop.

USES:

Bioethanol is mixed with isobutene which is a non renewable

petroleum derivative to produce ETBE (ethyl tertiary butyl

ether) .

It is used as a gasoline additive.


13/22


14/22

Fuel that is made from natural elements such as plants,vegetables and reusable materials.

SOURCES: Soya bean oil, Canola and Hemp oil.

Used instead of petroleum diesel and heating oil for buildings.

Advantages: Cleaner than diesel

Pleasant odour

Long engine life

PROS:

Available in abundance Cause no/less pollution

Available in solid, liquid and gaseous forms

Abundant energy can be formed and stored for use

Reduces the waste collected in landfills

Produces no harmful waste

CONS:

Competition for land

Use of agricultural crops like cassava, sugarcane

Production of bioenergy is time consuming

Low productivity

Low investment money for research


17/22

Use of plants like switch grass which can be grown in

poor soil conditions.

Also, it is better to use waste and organic residues for

the production of bioenergy so that there is no issues

over the land use.

Moreover, solar and wind energy are more cleaner

source of renewable energy and doesnt require muchland.


18/22

In Brazil, Angra 1 nuclear plant uses stored chemical

energy in sugarcane to produce 657 MW energy.

Korea uses the livestock excretions to produce biogas andthe bioenergy plant can produce 600 KW of energy in 24

hours.

Japan is investing US$ 7 billion in The Sunshine Project.

India successfully produces 10%of bioenergy for use.

Used cooking oil is convertedinto biofuel and is used invehicles in Yeoju-gun.


19/22

Projects are being undertaken in Aston University andUniversity of Manchester, UK, to find a novel way

of producing algal bio fuel.

Research is being carried out in US laboratories to find out

ways of breaking bonds between sugar molecules ofplant cell walls which is then a rich source for

bioenergy production.


20/22

It enhances to develop the Carbon Dioxide neutralpower systems.

Increasing biomass power by 30GW taking intoaccount of the crops and agricultural wastes.

20 MW project near Carlisle which will usepyrolysis to convert forestry residues to liquid biofuel.

Meeting bioenergy demands by overlayingthe global energy demand by increasing energy supply by

1000EJ by the year 2050.

Further 120 million tonnes of oil of biomass needs to be createdby 2020.
