Manuals, examples and quick start.
The workstation, the design basis, all drawings and documents, the annual simulation, economics, the component library and impact assessment, tools and licensing.
Step-by-step examples: new projects from scratch and from components, from a 10 MW grid-connected PEM plant to a 100 MW islanded ammonia project whose components are chosen by their impacts.
External benchmark of Hasim against measured plants, NREL SAM, HOMER Pro, US DOE H2A and HDSAM and the reference values of the Clean Hydrogen Partnership, the US DOE, IRENA and the IEA.
1. Load an example (Home ▸ Example). 2. Edit the design basis in the Properties panel. 3. Review drawings, tables and the annual simulation. 4. Print the design report.
If Hasim helped your work – a paper, a thesis, a report or a feasibility study – please cite it, so that others can find and check the method. Name the version you used; it is shown in Help ▸ About.
The plant was sized and its 8760-hour operation, levelised cost of hydrogen and design checks were computed with Hasim 2.3.0 (Muhsen, 2026; www.hasim-software.com).
