Prospects & Challenges of Biomass

& Biofuels usage in Power

Generation

Introduction

Enough Biomass resources in the world to cover the world’s

energy demand. (1)

Using Biomass sources for power generation is CO2 neutral.

More economically viable now with CDM and CER cert’s sale (for

certain situations - primarily on methane emission reduction).

Abundant Biomass resources in Asia

More than 30% of the world’s Biomass resources located in Asia. (1)

Cost competitive rates for labor input and transportation.

Various technologies and options available

Direct Biomass combustion

Generation of electricity through heat & steam

Biomass Liquefaction via Pyrolysis

Power generation by combustion of pyrolysis oil

Gasification of Biomass

Power generation using derived producer gas

Organic plant based oil (i.e. Crude Palm Oil - CPO)

Generation of electricity using CPO

Biogas anaerobic digestion

Power generation using scrubbed methane gas

Biomass Combustion

Relatively established and proven technologies

Economically viable for sizes between 6MWe to 15MWe



© SunTechnics 6

Economical viability of Biomass combustion

Example from a high cost country: Japan

Fuel cost around 5000 yen (USD 42) per ton wood waste Construction cost USD 2.7 million per MWe

Electricity selling price USD 12.5 cents per kWh

Estimated break-even (payback) time is 6 years

Eg. low cost: Malaysia

EFB fuel USD 6.3

USD 1.8 mio MWe

Elect sell USD 6.4c

Breakeven 7 yrs

Viable without subsidy

Prospective segments & challenges

Biomass Combustion power plant is attractive to:

Industrial Factories owners Plantation/Mill owners

Sugar cane (Bagasse)

Rice (Rice Husks)

Wood/Paper (Wood Wastes)

Corn (Corn Wastes)

Palm Oil (Empty Fruit Bunches, Shells)

Cassava (Roots, Stems)

Able to supply both Electricity and Heat (steam) for factory use

Main challenges:

securing the long term supply of Biomass fuel source at

stable prices

selling price of electricity, if connected to the grid to sell

electricity

Biomass Liquefaction via Pyrolysis

A process similar to Gasification

Heating of Hydrocarbons in zero oxygen condition

Condenses the vapors to obtain Bio-oil (pyrolysis oil)

Bio-oil is easily transportable, store and handle

Can be combusted in boiler for heat or electrical generation

Economical viability of pyrolysis oil

Quick Comparision

Crude oil (fossil) at

USD 50 per barrel

~ USD 12 per GJ (4)

EFB pyrolysis oil

~ USD 8 per GJ (4)

Suitable for factory

process heat & electric

Ref. (4)

Example solution for EFB pyrolysis oil

Attractive to Palm Oil Mill owners

Coverts EFB wastes into Bio-oil CER credit for better profitability

Closed cycle for mill’s waste

If tap POME for Biogas

Main challenge: Need cheap electricity

supply for the pyrolysis process

(can be obtained from Biogas plant)

Ref. (4)

Gasification of Biomass

Obtain producer gas (syngas) through heating of Biomass in

limited oxygen condition

Stoichiometric (normal) combustion has air-to-fuel ratio of 6:1

Sub-stoichiometric (gasification) has air-to-fuel ratio of 1.5:1

Syngas: H2 20%, CO2 12%, CH4 3%, CO 20%, balance N2

Economical viability of Biomass Gasification

Ref. (5)

USD 35 per ton

USD 25 per ton

USD 16 per ton

Small sized Biomass Gasifiers

Suitable for remote electrification

using wood chips / blocks

Ideal for small factories, mills

Electricity, process heat

Main challenges:

Small sized biomass needs tobe briquetted.

Maintenance in remote region

can be difficult and expensive

Challenges – Evironmental issues

"... carbon released from peat swamps in Indonesia and Malaysia

that had been drained and burned to plant palm oil trees." (8)

"The four-year study found that ... those 2 billion tons of CO2

account for 8 percent of the world's fossil fuel emissions." (8)

"Major power companies are divided on whether to continue or

pursue palm oil generation."(8)

Suitable situations & segments for Biofuel’s use

Non-productive land, plant Jatropha

Small scale CPO for electricity generation

Biofuels use in transportation vehicles

Vehicles difficult to be carbon neutral

Helps to reduce air pollution

Substrate storage and utilization

Output substrate is stabilized and can be applied to fields as a

liquid fertilizer.

Rich in nutrients including nitrogen (N), phosphorus (P),

potassium (K) and other trace elements.

Large sized Biogas system

Suitable for plantations, mills and

factories that has organic solid

wastes or waste water.

Able to produce large amount of

electricity and heat from animal

manure too.

Connect to the grid or for internal

factory use.

Main challenge:

Long term supply of organic

feedstock at reasonable price
