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.

Green Hydrogen
Matching renewable electricity with electrolyzer operation
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.
Fuel Cells
Fuel-cell electric vehicle refueling and duty-cycle realities
Refueling speed is only one part of a fleet decision. The useful comparison connects route, payload, dwell time, station design and seasonal conditions.
Fuel Cells
Stationary fuel cells for backup power and microgrids
A backup system earns its place through availability and recovery, not nameplate output alone. Load shape and fuel logistics are the starting point.
Infrastructure
Pipeline blending limits, materials and conversion questions
A blend percentage is a starting point, not a complete engineering answer. The network, meter, appliance and customer use must be read together.
Infrastructure
Safety codes, venting, detection and first-responder planning
Safety planning is a chain of controls and communication. Codes, physical layout, detection and response need to agree before a site opens.
Policy & Markets
Industrial demand clusters: steel, fertilizer and refining
A demand cluster is more than a list of customers. It is a shared system of volume, timing, infrastructure, quality and risk.
Policy & Markets
Offtake agreements that make clean hydrogen bankable
Bankability lives in the details that connect a product promise to delivery, measurement, certification and remedies when conditions change.

Where the transition is actually lived.
Hydrogen is one thread in a much wider energy conversation. These independent French-language publications cover the everyday end of it, and the desk reads them for that reason.
