Hydrogen power generation

Technology that generates electricity through an electrochemical reaction between hydrogen and oxygen, with water as the only byproduct.

A method that separates the formation of oxygen and hydrogen into different stages, locations, and rates, allowing hydrogen production directly from seawater without relying on freshwater supplies.

A type of engine being developed by ZeroAvia that uses hydrogen to power an aircraft, aiming for zero greenhouse gas emissions.

ZeroAvia's first product, a hydrogen-electric engine for aircraft.

Clyde Hydrogen's beta-stage prototype demonstrating two-stage hydrogen production with electrochemical reduction and catalytic hydrogen generation. Successfully operated continuously at pressures exceeding 100 bar under manual control.

Clyde Hydrogen's planned fully integrated pilot system incorporating automation for improved efficiency and scalability, scheduled for development by late 2025.

A fuel-cell engine for aviation.

An innovative hydrogen production system that separates electrochemical reduction from hydrogen generation into two distinct stages, enabling hydrogen production at high pressures with intermittent renewable energy sources. The beta-stage prototype has demonstrated continuous operation at pressures exceeding 100 bar.

A 900 kW hydrogen-electric engine developed by ZeroAvia, intended for larger regional planes.
