The inception of the journal Carbon and Hydrogen is driven by the imperative to align with the global energy transition towards a low-carbon economy and to provide a forum for the evolving scientific discourse in the field of energy and chemistry. The journal aims to provide a high-level platform for the discussion and exchange of scientific and technological research findings related to carbon and hydrogen, which are pivotal elements in the energy sector.

Carbon and Hydrogen represents a strategic evolution of the original journal, China Petroleum Processing and Petrochemical Technology (ISSN 1008-6234), within the international academic community, emphasizing an elevation of its global visibility and academic standing. The new title reflects the essential nature of petroleum chemical engineering, rooted in the chemistry of carbon and hydrogen, while maintaining full continuity with the established academic domain of the original journal.
