NASA is seeking information from potential sources for ASME certified high-pressure storage vessels for hydrogen, methane, and nitrogen, with a total capacity of 1,250 cubic feet across two vessels. The required vessels must meet 15,000 PSIG ASME standards using SA372 Grade J material or equivalent, with configurations including an assembly pack or individual vessel option. Performance of services will be at NASA’s John C. Stennis Space Center in Mississippi. Respondents must submit capability statements, past performance summaries for three similar projects within the last five years, and estimated delivery schedules. No budget amount is specified, and this is a sources sought notice, not a solicitation.
