Review of Design Coefficients№3 (SpecialA)Example of summary

of road map

Objective

of road map

• Japan uses larger design coefficients than Europe and the U.S., which have caused the following problems.

Difficult to import and use overseas products– Difficult to import and use overseas products.– Difficult to reduce hydrogen station construction costs– Pipes and valves are thick and large, which causes problems in

terms of operability and performance.• Review ministerial ordinances and exemplified

standards etc to enable construction of hydrogenstandards, etc. to enable construction of hydrogen stations using design coefficients similar to the U.S. and Europe.

【Legal measures】Revision of High Pressure Gas Safety Act, general laws (ordinances), g y , g ( ),

and specific laws (ordinances), and exemplary standards.

• Liquid hydrogen storage: Power consumption for collecting BOG※ s causes lower efficiency than other off-site type stations.※BOG:Boil Off Gas

Prediction of Station Efficiency in the Future

70MPaEfficiency HHV(LHV)%

Natural Gas reforming 64.0(60.0)% → 78.3(73.2)% 62.1(58.0)% → 76.8(71.8)%

※ The improvement prediction is calculated based on the actual average value measured in January and September 2009 at Senju.

Breakdown of efficiency improvement

◆Hydrogen production efficiency (natural gas steam reforming & PSA purification):60~65%HHV(Senju results) ⇒ 80%HHV expected

◆O ll di b ti ffi i f◆Overall adiabatic efficiency of compressor :52%(Senju 70MPa results) ⇒ 73% expected

Malfunction Case 2Hydrogen manufacturing unit malfunction1. State

・Through open inspection of the reaction tube, checkg p p ,for damage of the aluminum ball, deformation of the reaction pipe, and cracks near the elbow.

・Through the micro and fractured surface inspectionThrough the micro and fractured surface inspectionof cracked area, check for intercrystalline cracks andstriation.

2 CausesReaction

pipe2. Causes・The structure was one where thermal shrinkage at start/stop was

absorbed by the up/down movements of the reaction pipe, however the /d t i d d h th i t b i d b th

pipe

up/down movements are impeded when the inner tube is covered by the catalyst and heat exchange alumina ball.

・The repetition of start/stop in this state causes deformation of the top part of the inner tube, resulting in defects.

3.Measures/Improvements・Reduce the filling amount of the alumina ball to reduce covering of theg ginner tube.

・Increase material strength to reduce inner tube deformation and damage.44
