I. Overview of SWJTU and NEEC
Founded in 1896, Southwest Jiaotong University (SWJTU) was originally named Imperial Chinese Railway College;
SWJTU was born for rail transportation. So many China’s FIRSTs in rail transportation were from SWJTU:
The first independently designed and constructed Beijing-Zhangjiakou Railway;The first electrified railway ---- Baoji-Chengdu railway;The first internal combustion locomotive;The first electric locomotive;The first manned superconducting trial maglev;……The first fuel cell locomotive

II. Opportunity of Hydrail
the Eighth International Hydrail Conference Ryerson University – Centre for Urban Energy, Toronto, Canada , 2013.06.11~12
Fuel cell rail vehicles vs fuel cell buses and cars:
Duty cycles of rail vehicles are far less flexible and better for fuel cell performance;
Hydrogen delivery infrastructures for fixed rail transportation lines are less;
Investment of rail transportation is huge enough to absorb high cost of fuel cell power systems;
Passenger carrying capacity is much greater and operation cost is lower.

II. Opportunity of Hydrail
the Eighth International Hydrail Conference Ryerson University – Centre for Urban Energy, Toronto, Canada , 2013.06.11~12
Application of fuel cells in hydrail includes switcher locos and rail transportation vehicles:
Switcher locomotive:
Most of the switcher locos are powered by diesel engines, with low efficiency and high air pollution;
Advantages of fuel cell locos include clean, high efficiency and fuel economy;
Challenges include high power requirement, high cost and the market acceptance.

II. Opportunity of Hydrail
the Eighth International Hydrail Conference Ryerson University – Centre for Urban Energy, Toronto, Canada , 2013.06.11~12
Rail transportation vehicles:
Catenary of present rail transportation vehicles destroys modern city scenery greatly;
Catenary-free light rail vehicles (LRV) or trams based on fast charging develop fast these years;
Fuel cell powered LRV or trams will cut down investment of transportation line construction.

II. Opportunity of Hydrail
the Eighth International Hydrail Conference Ryerson University – Centre for Urban Energy, Toronto, Canada , 2013.06.11~12
Construction investment comparison of a fuel cell LRV line and a catenary LRV line:
20km LRV line, with 40 LRVs in operation; Investment of catenary based traction power system
exceeds $60 million*; According to present price, 300kW fuel cell system
costs $1.5 million, cost of 40 LRVs increases $60 million;
3000Nm3/h methane reforming hydrogen production plant cost less than $6 million;
Investment hydrail LRV line is near to that of catenary based LRV line, less than catenary-free LRV line.
* According to Chinese price with 1:6.5 exchange rate between USD and RMB

the Eighth International Hydrail Conference Ryerson University – Centre for Urban Energy, Toronto, Canada , 2013.06.11~12
Operation cost comparison of a fuel cell LRV line and a catenary LRV line:
Average power requirement of 40 LRVs in operation is about 5000 kW;
Electricity for rail traction is about ¥0.75 /kWh, operation cost for catenary LRV line is $577 /h;
Cost of hydrogen from methane steam reforming is ¥0.8~1.5/Nm3, take an average value, operation cost for a fuel cell LRV line is $553 /h;
Operation cost of a hydrail LRV line is also near to that of catenary based LRV line.
