Contemporary processes producing hydrogen from fossil fiiels or water, contribute to carbon dioxide emission. Thus, they have to be associated with capture and seąuestration of carbon dioxide. If so, eiectricity energy that can be also combined with C02 removal, on one side and hydrogen fuel on the other side. should be compared in a number of issues. The hydrogen large scalę transfer from a manufacturer to end-users requires new technological solutions and ensuring extremely careful safety measiires due to the wide explosive rangę of hydrogen and its high flammability. It is elear that at present, hydrogen transfer cannot compete with eiectricity transfer. Use of engines powered by hydrogen in transportation sector, poses yet unsolved problem of hydrogen storage in cars. Neither compressed, nor liquefied hydrogen might be a good solution. A compression as well as liquefaction reąuires high energy input. Practical hydrogen storage demands a major technology breakthrough, most likely in solid-state materials capable of storing a sufficient amount of hydrogen. Such barriers would not oceur in transportation sector powered by hybrid engines (hydrocarbon fuel drive engine working alternately with electrical motor). Summing up, the technological breakthrough of production and large scalę use of hydrogen could be expected after 30 up to 40 years. However, climate protection is immediately needed.
