CPD ROOM 1: TRIGENERATION (phase 1)

In this first phase, has chosen Tissat Distributed Generation. To this end, we have developed a trigeneration system, in which, while generating electricity for the CPD, produce chilled water for air conditioning the same, using waste heat from combustion engines, transferring to a cooling technology "Absorption "high efficiency, which provides for each kWt kWf 1, which corresponds to 1 kWe.

WALHALLA EFFICIENCY

If we compare a conventional CPD, powered by electricity from the power plant more efficient gas in Spain (55%), we find a scenario in which they play the following factors:

Conventional CPD:

High efficiency Combined Cycle = 55%
Electrical network losses = 15%
CPD door Efficiency = (100-15) * 55/100 = 46.75%
Electric chiller EER = 3
Consumption of CPD = 1 MWe
Electricity consumption for cooling the CPD = 1/3 MWe
Total consumption of CPD = 1 + 1/3 = 1.33 MWe
Primary energy consumption = 1.33/0.4675 = 2.84 MWt gas
Annual gas consumption MWt = 2.84 * 8760 = 24,878 h MWht
Production of CO2 = 24,878 MWht * 0204 = 5075 Tn Tn CO2/MWht CO2/year

Walhalla CPD:

Gas engine efficiency = 40.6%
Electrical network losses = 0%
CPD door Efficiency = 40.6%
Absorption chiller COP = 1
Consumption of CPD = 1 MWe
Electricity consumption for cooling the CPD = 0 MWe
Total consumption of CPD = 1 + 0 = 1 MWe
Primary energy consumption = 1/0.406 = 2.46 MWt gas
Annual gas consumption MWt = 2.46 * 8760 = 21,550 h MWht
Production of CO2 = 21,550 MWht * 0204 = 4396 Tn Tn CO2/MWht CO2/year

Primary energy savings:

A = (2.84/2.46*100)-100 = 15.4%
A CO2 = 5075-4396 = 678.8 Tn CO2/year

Equivalence in vehicles:

Average production of CO2 per vehicle = 175 g CO2/km
Average annual Tour = 25000 Km
Production of annual CO2 = 175 * 25000/106 = 4,375 tons CO2 per year
Equivalence per car = 678.8 CO2/year Tn / Tn CO2/year 4375 = 155 cars

CPD ROOM 2: FUEL CELL (phase 2)

In a second phase, Tissat plans to install a hydrogen fuel cell of the same power, with the following advantages:

Walhalla Hydrogen CPD:

Electrical efficiency = 47%
Degree of thermal utilization = 50%
Residual heat high temperature = 100%
Electrical network losses = 0%
CPD door Efficiency = 47%
Absorption chiller COP = 1.4
Consumption of CPD = 1 MWe
Electricity consumption for cooling the CPD = 0 MWe
Total consumption of CPD = 1 = 1 MWe
Primary energy consumption = 1/0.47 = 2.13 MWt gas
Annual gas consumption MWt = 2.13 * 8760 = 18,658 h MWht
Production of CO2 = 18,658 MWht * 0204 = 3806 Tn Tn CO2/MWht CO2/year

Primary energy savings:

A = (2.84/2.13 * 100) -100 = 33.33%
A CO2 = 5075-3806 = 1269 Tn CO2/year

Equivalence in vehicles:

Average production of CO2 per vehicle = 175 g CO2/km
Average annual Tour = 25000 Km
Production of annual CO2 = 175 * 25000/106 = 4,375 tons CO2 per year
Equivalence per car = Tn CO2/year 1269/4375 = 290 cars Tn CO2/year
