NTPC demonstrates zero-emission ‘hydrogen cooking’


NTPC Energy Technology Research Alliance (NETRA), the R&D wing of India’s largest integrated power utility NTPC, has demonstrated successful hydrogen cooking with the supply of hydrogen from an existing green hydrogen plant at its campus in Greater Noida.

“Burning characteristics of hydrogen are much different from LPG or PNG wrt flame color (almost invisible), flame temperature (1200-1500 degrees C), flame propagation speed, etc. Also, unlike LPG or PNG, hydrogen cannot be premixed with air before its ignition – else it would form an explosive mixture,” stated NETRA.

“Considering the above, a hydrogen burner was designed and used in a modified cookstove to prepare food. It may also be mentioned that the emission from hydrogen burner is only water vapor with zero carboneous element.”

NTPC has successfully commissioned a blending project that incorporates green hydrogen with PNG (piped natural gas) at Kawas. A green hydrogen mobility project in Leh is set to be commissioned. Besides, another project for setting up green hydrogen-based microgrids in remote locations for Indian Army is in progress.
