Cover Story: There are many pathways for utilizing surplus clean electricity. In this project, we introduce the importance of one of the power-to-gas pathways. The enrichment of natural gas with hydrogen has been identified as a promising pathway for power-to-gas technology, with the potential to reduce emissions while achieving a feasible return on investment. This paper aims to investigate the financial and environmental returns associated with producing and storing electrolytic hydrogen for injection into the natural gas feed of a manufacturer’s combined heat and power plants (CHPs). A mathematical methodology was developed for investigating the optimal operation of the integrated system (power-to-gas along with the current system) by considering hydrogen-enriched natural gas.
