Green Hydrogen
Electrolyzer efficiency metrics from kWh to levelized cost
Efficiency is not one number. It is a chain from electricity input to usable hydrogen, shaped by loading, balance of plant and replacement timing.
Section desk
How electricity, water, certification and operating choices shape hydrogen production. Read the WHEC Hydrogen explainers and follow each question into the wider system.
04 explainers
A measured, practical starting point.
This desk connects equipment, operating conditions and decisions. Each explainer starts with a clear boundary, names the trade-off that matters and points to another part of the system so a reader can keep testing the idea.

Green Hydrogen
Efficiency is not one number. It is a chain from electricity input to usable hydrogen, shaped by loading, balance of plant and replacement timing.

Green Hydrogen
The quality of a renewable supply is a time series, not a label. Matching the supply to the electrolyzer reveals the operating decisions a project must make.

Green Hydrogen
How switching fuel in a forge changes fire, heat treatment and metal behaviour, and what industrial process heat decarbonisation means for shops.

Green Hydrogen
A hydrogen project that sits near a mine, a concentrator or a legacy impoundment shares one resource with it: water, and the documents that describe where that water goes. Reading a tailings management plan is therefore not a courtesy to the neighbour. It is a way to check transport assumptions, recovered water volumes and the governance chain that a hydrogen site will also be asked to document. The vocabulary matters first: what a plan calls thickened tailings, paste or filtered tailings changes what is being claimed about water and about the deposit itself.
