Steam methane reformation hydrogen production costs from

The analysis showed, with various "value adders" (e.g., oxygen sales and carbon-emission-offset credits), the cost of wind-source gaseous hydrogen delivered by pipelines from production point to distant markets (about 200-1000 mi.) at an untaxed wholesale energy unit cost will be competitive with market prices (in 2005) of gasoline and hydrogen fuel made from natural gas by steam methane reforms (SMRs). [Pg.347]

The (additional) costs of C02 capture in connection with hydrogen production from natural gas or coal are mainly the costs for C02 drying and compression, as the hydrogen production process necessitates a separation of C02 and hydrogen anyway (even if the C02 is not captured). Total investments increase by about 5%-10% for coal gasification plants and 20%-35% for large steam-methane reformers (see also Chapter 10). [Pg.183]

Much work remains to be done to determine the most overall cost effective solution and establish the business case for deployment of a hydrogen infrastructure. At least in the early stages, the most likely candidate for the production of hydrogen would be from the steam reforming of methane at stationary sites off the fuel cell vehicle. Unfortunately, many of the potential C02 reduction benefits from hydrogen fuel cell vehicles would not be fully realized until renewable resources are developed. [Pg.189]

The application of membrane reactors to methane reforming has also been evaluated in two recent studies. A technical and economic evaluation of the use of dense Pd-membrane in methane steam reforming has been presented by Aasberg-Petersen et aL [6.10]. They assumed a thin (2 Lim thick) Pd membrane, which exhibited perfect separation and, as a result, the pure hydrogen product was taken from the permeate side of the membrane. No sweep gas was used on the permeate side of the reactor. This necessitated compression of the low pressure hydrogen product. The authors concluded that membrane-based reforming using a dense film membrane became attractive only in the cases where electrical costs were low. [Pg.228]
