Hydrogen is the most abundant element in the universe and a versatile energy carrier. The hydrogen generation market encompasses the technologies that produce hydrogen from various feedstocks: natural gas, coal, biomass, and water. As the world seeks to decarbonize, the hydrogen generation market is projected to grow. The color of hydrogen matters: grey (from natural gas, without carbon capture), blue (from natural gas with carbon capture), and green (from water electrolysis using renewable electricity).
The growth trajectory of the hydrogen generation market is heavily influenced by the need to decarbonize hard-to-abate sectors: steel, cement, chemicals, and heavy transport. The hydrogen generation market for "green hydrogen" is the fastest-growing segment, driven by falling renewable energy and electrolyzer costs. The hydrogen generation market for "blue hydrogen" is also growing, as it provides a lower-carbon option using existing natural gas infrastructure. The hydrogen generation market for "grey hydrogen" is still the largest (by volume), but its share is declining.
Furthermore, the hydrogen generation market is segmented by technology. The hydrogen generation market for "steam methane reforming" (SMR) is the most mature and lowest cost, but produces CO2. The hydrogen generation market for "SMR with carbon capture" (blue) adds cost but reduces emissions. The hydrogen generation market for "electrolysis" (using electricity to split water) is the greenest, but currently the most expensive. The hydrogen generation market for "alkaline" electrolysis is mature; "PEM" electrolysis is growing; "solid oxide" (SOEC) is emerging.
The hydrogen generation market is also segmented by application. The hydrogen generation market for "petroleum refining" (hydrocracking, desulfurization) is the largest current use. The hydrogen generation market for "ammonia production" (fertilizer) is the second largest. The hydrogen generation market for "methanol production" is also significant. The hydrogen generation market for "transportation" (fuel cell vehicles) is small but growing. The hydrogen generation market for "power generation" (gas turbines burning hydrogen) is emerging.
The hydrogen generation market for "distribution" is a key enabler. Hydrogen can be transported as a compressed gas (by tube trailer or pipeline) or as a liquid (cryogenic). The hydrogen generation market for "liquid hydrogen" (LH2) is energy-intensive. The hydrogen generation market for "carriers" (ammonia, LOHC) are being developed for long-distance transport.
Looking ahead, the hydrogen generation market will see the deployment of "gigawatt-scale" electrolyzers. The hydrogen generation market for "offshore" hydrogen production (using wind power) is being piloted. The hydrogen generation market for "underground" hydrogen storage (in salt caverns) will enable seasonal storage. As the energy transition progresses, the hydrogen generation market will become a cornerstone.
