Hydrogen production plants

Feed gases to most, if not all, methanation systems for substitute natural gas (SNG) production are theoretically capable of forming carbon. This potential also exists for feed gases to all first-stage shift converters operating in ammonia plants and in hydrogen production plants. However, it has been demonstrated commercially over a period of many years that carbon formation at inlet temperatures in shift converters is a relatively slow reaction and that, once shifted, the gas loses its potential for carbon formation. Carbon formation has not been a common problem at the inlet to shift converters. It has been no problem at all in our bench-scale work, and it is not expected to be a problem in our pilot plant operations.

Air Products plans on constructing a new hydrogen production plant in Port Arthur, Texas to supply 110 million standard cubic feet per day of hydrogen to Premcor Refining and others on Air Product s Gulf Coast hydrogen pipeline system. 

Figures 14.9 and 14.10 show the geographical locations of major hydrogen production plants for the REF and REN-CCS scenarios, respectively.

The investments are estimated on the basis of long-term experience in building hydrogen production plants and on the assumption of budding 10 identical units in order to optimize the construction costs. Table 9.4 gives the plant cost estimate as a percentage of the delivered equipment costs [99]. Such an estimate does not... 

H2 Refuelling station in Barcelona. Electrolysis production of hydrogen, which will be supplied at high pressure to three buses participating in the European CUTE project. It will be the first hydrogen production plant with a solar photovoltaic system, producing 10% of electricity needs.

HEEP is expected to be similar to the IAEA software DEEP which is being used to perform economic analysis and feasibility studies related to nuclear desalination in the IAEA and other member states. It is expected that HEEP will have similar architecture to DEEP but with the possibility of easy update and future expansion. Various major processes and technologies are to be incorporated in the HEEP programme as the basis for modelling the performance and cost characteristics of hydrogen production plants. The pre-alpha version of HEEP has been completed and the release of the beta version is expected to be in the first quarter of 2009.
