Samenvatting:
As part of the International Energy Agency Hydrogen ImplementingAgreement, an evaluation tool to assist in the design, operation and
optimisation of hydrogen demonstration facilities is under development. Using
commercially available flowsheet simulation software (ASPEN- Plus) as the
integrating platform, this tool is designed to provide system developers with
a comprehensive data base or library of component models and an integrating
platform through which these models may be linked. By combining several
energy system components a conceptual design of a integrated hydrogen energy
system can be made. As a part of the tool and connected to the library are
design guidelines which can help finding the optimal configuration in the
design process. The component categories considered include: production,
storage, transport, distribution and end use. Many component models have
already been included in the initial test platform. The use of the tool will
be illustrated by presenting the results of a specific sample system that has
been designed and assessed with use of the tool. The system considered is a
decentralized renewable hydrogen system in which the hydrogen is produced by
biomass gasification or pyrolysis, the produced hydrogen is transported
through a pipeline or with a tank truck. The storage options that are
considered are liquid hydrogen and compressed gas. The hydrogen is dispensed
through a refueling station. Several options for integration are conceivable;
i.e. storage of the hydrogen can take place centrally or district heat of a
gasification unit can be used to generate electricity for liquefaction, etc.
With use of the tool several configurations with different components and
various integration options have been examined. Both the results of the
modeling effort and an assessment of the evaluation tool will be presented. 5
