Transcripción del abstract original del autor: New natural gas transmission pipeline systems traversing regions rich in renewable-source energy may be built with line pipe capable of 100% gaseous hydrogen (GH2), for future conversion to "renewables-hydrogen" service. Since well-constructed and well-maintained pipelines have very long service lives, the increased investment required for construction with GH2-capable line pipe may be justified. These pipeline systems may be retrofitted with compressors and other fittings necessary for future GH2 service, for the nascent "renewables-hydrogen economy". Although industry has been safely pipelining GH2 for decades, these systems are not designed for >14 MPa and frequently-varying pressure, and for high-capacity, long-distance, cross-country collection, as required by 2renewables-hydrogen" service (RHS). Optimal line pipe material for RHS is unknown, although Nippon Steel has tested extensively for hydrogen-induced-cracking. Thus, a new International Hydrogen Transmission Test Facility (IHTTF) is needed. The Eastern Siberia Far East (ESFE) Pipeline Project provides a unique opportunity to research some of the issues of alternative energy developments.
