Agenda
Problem Statement
Current Solution and its issues
About Biomass Gasification
The Business model
Automated system developed for Rural
Electrification & Off-Grid applications

About Ankur Scientific

Problem Statement
No / Bad Energy Access in rural areas.
Limited supply of grid electricity and
extensive use of diesel gensets.
No / Limited Rural Development due to
lack of Modern Renewable Energy systems.
Lack of Employment Opportunities.
Migration to Urban areas leading to
infrastructural stress.

Solution?
OFF-GRID, Decentralized
Renewable Energy Systems for
Cheap, Sustainable power to
all.

RE Solution?
 Solution should be –

Simple
Sustainable
Scalable
 Sustainable from the point of view of
Individual and Community involvement
Environment
Health & Safety

Current Electricity Options for
Rural Areas
Diesel based gensets

Diesel based Power Generation

operating in the
space
4. Good After Sales
service

1. Very high cost of
power
2. Environmentally
unfriendly
technology

3. Battery disposal issues
and thus
environmental issues
4. Very site and season
dependent

Biomass Gasification Technology
One of the best options of Off-Grid RE.
Most relevant at the level we are looking at.
Wide range of power generation systems
available right from 10-kWe to 1.6-Mwe
levels.

Can use different available Biomass / agriresidues that are available in the specific
rural areas.

What is Biomass Gasification?

What is Gasification?
Gasification is conversion of various
biomasses to a combustible (something
that can be burnt) gas called Producer
Gas.
This gas can then be burnt in Engine
Gensets to produce electricity or can be
used for process heat applications.

Applications
Power Generation
Village Electrification
 Irrigation Pumping
 Captive Power (Industries)
 Grid-fed Power from Energy
 Plantations on Wastelands
 Simultaneous Charcoal and
 Power Production

Thermal
Applications
Hot Air Generators
 Dryers
 Boilers
 Thermic Fluid Heaters

 Ovens
 Furnaces & Kilns

Modes of Power Generation
1. Dual Fuel Mode (Fuel = Diesel + Biomass)
 Uses a Diesel engine genset.
 60-75% of diesel replacement
 Typical consumption of about 5 – 6 kgs of rice husk or
about 4 kgs of woody biomass for each litre of diesel
saved.
 Sensible, if and only if diesel mode operation is
practiced.

2. 100% Gas Mode (Fuel = Only Biomass)
 Uses a Producer Gas engine genset.
 Need 1.3 kgs of wood/ 2 kgs of rice husk to generate 1
unit of electricity.

Environmental Aspects
Water

Air

Used in re-circulation mode with
zero discharge. Occasional ph
adjustment and simple treatment
may be needed.
Gasifier does not release gas to the
atmosphere.
Combustion in user equipments
(connected to gasifier) is much
cleaner compared to liquid fuels

Environmental Aspects(contd.)
Solid
Waste
Noise

Charcoal can be used for any thermal
heat application.

Biological ash can be returned to the
soil

In case of major user equipment i.e.
genset, noise level is lower than with
100% liquid fuels.

Biomass materials contain negligible Sulphur

The Ideal Models
 Set up multiple small systems of 11-kWe and 40-kWe level

ratings for Rural Electrification with Centralized control and
monitoring if required.
 Set up 200-kWe or higher level Off-Grid power plants

 Use locally available wastes / agri-residues
 Provide / Sell Power to Communities / Private Industries /
Utilities
 Generate high energy, high value charcoal & biochar as byproduct

Features of ‘Ankur’ Plug & Play
systems
(specifically developed for Multiple systems in a
Cluster be it for Rural Electrification, Islands &
also for Telecom Towers)

To

‘Ankur Plug & Power - Features
