A Global Review of the Hydrogen Energy Eco-System

Climate change primarily caused by the greenhouse gases emitted as a result of consumption carbon-based fossil fuels is considered one biggest challenges that humanity has ever faced. Moreover, Ukrainian crisis in 2022 complicated global energy and food status quo more than ever. The permanency this multifaceted fragility implies need for increased efforts to have independence requires long-term solutions without through use clean, zero-carbon renewables energies. Hydrogen technologies strong potential emerge an eco-system its production-storage-distribution-utilization stages, with synergistic integration solar-wind-hydraulic-nuclear other zero-carbon, clean renewable resources, existing infrastructure. In paper, we provide review hydrogen need, related policies, practices, state art production, transportation, storage, utilization.
