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

6. Advantage
- What Is Cogen
(Air conditioning)
6
Cogeneration is a process system that produce both electricity
& steam (processed for district cooling)

7. AdvantageCogen Versus Power Plant
(air conditioning)
7

8. AdvantageCogen Benefit To Melaka
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.

9. AdvantageHTJ Green City Reduce CO2 Emisson
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

11. Advantage-
District Cooling Versus Cogeneration
Conventional district cooling
Cogeneration
1 District Cooling use Electric chiller (ECC)
& R14 refrigerant harm-full 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
3 To run ECC, electricity is used originated
from power plant. 12.6MW coal plant
emit 79,000 ton carbon per annum
11
Cogen use Steam Chiller &Lithium
Bromide( salt) refrigerant, not harm to
environment
Cogen efficiency 85%, saving 30% gas
fuel compare gas power plant.
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.
5 District cooling an old version technology,
less value green technology for CO2
reduction to reduce global warming.
Cogen use HRSG, to RECOVER heat
from wasted to air.
Cogen use lesser fuel energy and a
12.6MW cogen plant produced 4,326 ton
CO2 per annum.
Cogen, a green technology initiative
reduce CO2 emission, fuel saving. Reduce
global warming.
