DESCRIPTION
Malaysia's pledge: To reduce carbon emission up to 40% in terms of emission intensity of GDP by 2020 compared with its 2005 levels. Green technology refers to product, equipment or system which comply to the following criteria: * It minimise environmental quality degradation * It has low or zero GHG emission * It is save to be used and provide better and healthy environment to all life * Save energy and natural resource * Promote renewable energy resource Cogeneration system is a green technology system since it has high efficiency thus save energy

Malaysia's pledge: To reduce carbon emission up to 40% in terms of
emission intensity of GDP by 2020 compared with its 2005 levels
Green technology refers to product, equipment or system which comply
to the following criteria:
* It minimise environmental quality degradation
* It has low or zero GHG emission
* It is save to be used and provide better and healthy
environment to all life
* Save energy and natural resource
* Promote renewable energy resource
Cogeneration system is a green technology system since it has high
efficiency thus save energy

(Seksyen 1.3 : Dasar Teknologi Hijau Negara)
Sektor Tenaga
• Sektor bekalan Tenaga : Aplikasi Teknologi hijau dalam
penjanaan tenaga dan pengurusan bekalan tenaga,
termasuk penjanaan bersama (co-generation) di
sektor industri dan komersil ; dan
• Sektor Penggunaan Tenaga : Aplikasi teknologi hijau dalam
semua sektor penggunaan tenaga dan dalam program

ADVANTAGES
Advantage
- What Is Cogen
Cogeneration is a process system that produce both electricity & steam (processed for district cooling)
6
(Air conditioning)
7
(air conditioning)
Advantage-
Cogen Versus Power Plant
By having Cogen, Melaka is supporting
green technology industry as aimed by
Melaka Green Technology Council
Melaka owns equity as cogen plant owner ,
contribute long term State income based on
equity.
By having Cogen, HTJ Green City contribute
CO2 emission reduction.
8
Advantage-
Cogen Benefit To Melaka
GHG emission per annum coal plant= KWHe xGHG rate =12,600 x24x365 x0.8x949 = 83,797 ton of CO2
GHG emission per annum gas plant= KWHe xGHG rate = 12,600 x24x365 x0.8x428 = 37,792 ton of CO2
GHG emission per annum gas DC= KWHe xGHG rate =12,600 x24x365 x0.8x148 = 13,068 ton of CO2
GHG emission per annum COGEN= KWHe xGHG rate =12.600 x24x365 x0.8x49 = 4,326 ton of CO2

Advantage-
HTJ Green City Reduce CO2 Emisson

Conventional district cooling Cogeneration
1 District Cooling use Electric chiller (ECC)
& R14 refrigerant harm-full to
environment
Cogen use Steam Chiller &Lithium
Bromide( salt) refrigerant, not harm to
environment
2 ECC use electricity TNB power plant. 1
MWh electricity produced consume
7million BTU gas. Plant efficiency 55%,
4.2 million BTU of gas wasted for each
1MWh
Cogen efficiency 85%, saving 30% gas
fuel compare gas power plant.
3 To run ECC, electricity is used originated
from power plant. 12.6MW coal plant
emit 79,000 ton carbon per annum
Cogen use lesser fuel energy and a
12.6MW cogen plant produced 4,326 ton
CO2 per annum.
4 Even SAC is used (gas direct firing), heat
wasted since NO heat recovery.12.6MW
DC plant produce 13,068 ton CO2 per
annum.
Cogen use HRSG, to RECOVER heat
from wasted to air.
5 District cooling an old version technology,
less value green technology for CO2
reduction to reduce global warming.
Cogen, a green technology initiative
reduce CO2 emission, fuel saving. Reduce
global warming.
Advantage-
District Cooling Versus Cogeneration
