Green Hydrogen 101: What It Is and Why It Matters

Green hydrogen is produced by splitting water using renewable electricity, creating a clean energy carrier that stores power for when the sun isn’t shining and the wind isn’t blowing, strengthening resilience across sectors.

Green Hydrogen 101: What It Is and Why It Matters

Unlike grey hydrogen from natural gas or blue hydrogen paired with carbon capture, green hydrogen avoids fossil inputs and carbon lock-in, aligning long-term climate goals with near-term industrial and grid needs responsibly.

Alkaline, PEM, and Solid Oxide Compared

Alkaline systems offer mature, cost-effective operation; PEM excels at rapid response to variable renewables; solid oxide targets high-temperature efficiency. Matching technology to use case and grid dynamics is crucial for reliable outcomes.

Chasing Higher Efficiency and Lower Costs

Manufacturers target improved catalysts, higher current densities, and modular designs. Efficiency today often ranges near the mid-60s percent (LHV), with innovations aiming to cut electricity use and simplify balance-of-plant components significantly.

Storage, Transport, and Safety: Turning Molecules into a System

Compressed Gas, Liquid Hydrogen, and Energy Carriers

Hydrogen can be compressed for shorter routes, liquefied for higher density transport, or bound in carriers like ammonia or liquid organics. Each option balances cost, efficiency, infrastructure compatibility, and end-use requirements carefully.

Safety by Design and Culture

Hydrogen disperses quickly but requires proper ventilation, detection, and materials selection. Transparent procedures, training, and shared incident learnings build trust, ensuring communities feel confident near production and refueling facilities.

Decarbonizing Industry: Steel, Chemicals, and Beyond

Projects are replacing coal in ironmaking with hydrogen-based direct reduction, producing sponge iron for electric arc furnaces. Early plants suggest substantial emission cuts and a path to premium low-carbon steel markets internationally.

Decarbonizing Industry: Steel, Chemicals, and Beyond

Switching grey to green hydrogen in ammonia plants and refineries removes large emissions sources, while hydrogen or hybrid solutions can deliver high-temperature industrial heat where electrification alone struggles technically and economically.

If you work in industry, tell us about bottlenecks—intermittency, water quality, or certification. We are compiling vendor-neutral guides and want your input to make them genuinely useful for teams making tangible progress.

Clean Mobility: Fueling Buses, Trucks, Ships, and Planes

Fleet pilots show fuel cell buses and trucks delivering quiet operation and predictable routes. One driver noted hearing birds at dawn for the first time at a depot once dominated by idling diesel engines daily.

Policy, Water, and Community: Making Projects Responsible

Incentives and Market Signals

Policies like tax credits, contracts for difference, and robust green hydrogen standards accelerate investment while rewarding measurable emissions cuts. Clear certification helps buyers trust climate claims and suppliers plan credible delivery.

Water Use and Local Context

Electrolysis needs about nine liters of water per kilogram of hydrogen, plus treatment. Using reclaimed or desalinated water and prioritizing local needs can align projects with drought resilience and community priorities thoughtfully.
