But….

Hydrogen Capability Currently Exists for Industrial

Units

Siemens has considerable experience in refinery gas fuels containing

high levels of H2

Some experience with Synthetic Fuels containing H2 and CO; heavily

diluted with Nitrogen (not commercial)

Package changes necessary due to H2 fuel

Wet injection methods applied to provide exhaust emission

suppression

Package Consideration

Hydrogen Embrittlement

Ensure fuel system pipework and fitting of suitable material

Martensitic steels particularly susceptible

Stainless steel (“300” series) used as standard (pipework and fittings)

Slide 19

Hydrogen Use For Power Production ?

Conclusion

Wait

DOE’s long-term program for use of H2 fuel (from coal) in large-scale

utility power projects

Don’t Wait

Use commercial products suitable for high-content H2 fuel in

industrial-sized Distributed Generation/ Cogeneration

Allows proof of concept for high H2 content fuels

Provides high efficiency projects for municipalities, universities, etc.
