An overview of the IAEA HEEP software and international programmes on hydrogen production using nuclear energy

Recent years have witnessed an increasing interest in hydrogen production using nuclear energy. A number of countries are actively exploring the option of nuclear hydrogen production and have established concrete roadmaps for near and far term achievements. This paper presents a summary of information presented at some IAEA technical meetings on status of nuclear hydrogen production including ongoing related R&D activities in Member States. The paper highlights, in addition, the IAEA hydrogen economic evaluation programme (HEEP) which has recently been developed under agreement and in collaboration with the BHABHA Atomic Research Centre (BARC). HEEP software can be used to perform the economics of the most promising processes for hydrogen production. Current processes considered in HEEP are: high and low temperature electrolysis, thermo-chemical processes including S–I process, conventional electrolysis and steam reforming. HEEP software is also suitable for comparative between nuclear and fossil energy sources, and for solely hydrogen production or cogeneration with electricity. The HEEP modelling includes various aspects of hydrogen economy including storage, transport, and distribution with options to eliminate or include specific details as required by the users.
