Hydrogen value chain covers production (PEM, ALK, SOEC electrolysis), storage and transport (70 MPa, LH2, ammonia carrier), refueling (70 MPa) and fuel cells (FCEV, stationary). Nel ASA, Linde (liquefaction), Siemens Energy (PEM electrolyzer), Plug Power and Hexagon Purus (high-pressure tanks) are key players.

FAQ
Q PEM, ALK or SOEC?
A
ALK: mature, cheap, runs on pure water (large-scale + wind/solar curtailment). PEM: compact, dynamic (distributed + refueling, but precious-metal catalysts). SOEC: highly efficient (85%+, 700°C steam, R&D).
Q Grey, blue, green hydrogen?
A
Grey: from natural gas/coal (CO2-intensive), 95% of today's H2. Blue: grey + CCS. Green: electrolysis with renewable power (zero-carbon). EU RED III subsidizes green.
Q Hydrogen refueling stations?
A
Compressors (Howden, Hofer), storage (Hexagon Purus, CIMC), dispensers (Linde, Air Liquide), chillers (Bauer). EU mandates stations every 200 km, backbone network by 2030.
