Hydrogen for Cooking: A Review of Cooking Technologies, Renewable Hydrogen Systems and Techno-Economics

Hydrogen research and analysis

A hydrogen cooking system using flameless combustion through a complete oxidation reaction with a heterogeneous catalyst, operating at lower temperatures around 500°C (932°F). This design is safer due to lower temperatures and absence of flashback risk.

Cooking systems that operate on a mixture of natural gas and hydrogen, or use completely different designs combining both fuels.

A hydrogen cooking system using conventional flame combustion design with H2 as fuel, producing temperatures between 1,200°C and 2,100°C. The only emission is water vapor, but requires a built-in flame arrestor to prevent flashbacks.

Hydrogen cooking systems using flameless combustion through complete oxidation with a heterogeneous catalyst, operating at approximately 500°C. Safer due to lower temperatures and no flashback risk.
