Golden hydrogen

Hydrogen is a colorless compound to which symbolic colors are attributed classify it according the resources used in production, production processes, such as electrolysis, and energy vectors, solar radiation. Green hydrogen produced mainly by electrolysis of water using renewable electricity from an grid powered wind, geothermal, or hydroelectric power plants. For grid-powered electrolyzers tendency go larger reach gigawatt-scale. An evolution opposite direction integration photophysics sunlight harvesting electrochemistry molecule splitting generator units, with each unit working at kilowatt-scale, less. Solar generators intrinsically modular, needing multiplication units To differentiate these two fundamentally different technologies term ‘golden hydrogen’ proposed, referring modular generators. Decentralized golden complementary centralized, energy-intensive green production. The differentiation between will facilitate introduction additionality principle clean policy.
