Abstract
Systems and methods for producing green hydrogen from a source material (e.g., biowaste) are contemplated. The source material is at least partially dehydrated to produce a dried intermediate and recovered water. The dried intermediate is pyrolyzed to produce syngas and a char. The recovered water is electrolyzed to produce oxygen and green hydrogen.
Claims18
A method of producing green hydrogen, comprising:
- at least partially dehydrating a source material to produce a dried intermediate and recovered water;
- feeding a first portion of the recovered water to a hybrid chiller to be used as a cooling stream for a condenser;
- feeding the dried intermediate to at least one thermal convertor via an airlock mechanism, wherein the airlock mechanism ensures the at least one thermal convertor remains oxygen-free for pyrolysis;
- pyrolyzing the dried intermediate to produce a syngas and a char;
- and
- electrolyzing a second portion of the recovered water to produce oxygen and the green hydrogen.
3 more elements
A system for producing green hydrogen from a biowaste, comprising:
- a dryer configured to use a dried hot air stream to at least partially dehydrate the biowaste, and produce recovered water and a dried biowaste;
- a hybrid chiller configured to receive a first portion of the recovered water to be used as a cooling stream for a condenser;
- at least one thermal convertor configured to receive the dried biowaste via an airlock mechanism, wherein the airlock mechanisms ensures that the at least one thermal convertor remains oxygen-free for pyrolysis;
- an electrolyzer configured to electrolyze a second portion of the recovered water to produce oxygen and the green hydrogen;
- the at least one thermal convertor configured to pyrolyze the dried biowaste to produce a syngas and a char;
- and
- a co-generation facility configured to utilize the syngas to produce electricity.
