AI Technical Summary

Technical Problem

Existing hydrogen production technologies suffer from problems such as excessive reliance on agricultural and food resources, stringent water quality requirements, and high energy barriers, making it difficult to achieve low-cost, low-energy-consumption green hydrogen production.

Method used

A multi-enzyme reaction system using formaldehyde and water as co-substrate is employed. High-temperature enzymes generate hydrogen gas in a buffer solution. Through the synergistic action of enzymes such as α-glucan phosphorylase and phosphogluconomutase, glucose 6-phosphate is generated, and hydrogen gas is produced through a multi-step enzymatic reaction. This simplifies the process of utilizing carbohydrates in smaller molecules and reduces the energy barrier of water resources.

Benefits of technology

It achieves a highly efficient hydrogen production reaction without the addition of exogenous ATP, reduces costs, simplifies the hydrogen production process, is applicable to different water quality conditions, especially seawater or sewage, and avoids excessive dependence on agricultural and food resources.

Abstract

This invention provides a hydrogen production reaction system using formaldehyde and water as co-substrates, comprising a buffer solution, maltodextrin, formaldehyde, magnesium chloride, manganese chloride, NAD, benzyl viologen, sodium phosphate, α-glucan phosphorylase, phosphogluconomutase, glucose-6-phosphate dehydrogenase, phosphogluconate dehydrogenase, phosphogluconolactonease, flavoxase, hydrogenase, 6-phosphate hexulose synthase, phosphogluconose isomerase, and phosphogluconose isomerase. This invention also provides a corresponding hydrogen production method. This invention utilizes formaldehyde and water to generate hydrogen, avoiding excessive dependence on agricultural resources; simultaneously, by replacing traditional carbohydrates with high-energy formaldehyde as the substrate, it lowers the energy barrier of the co-substrate water and simplifies the process of carbohydrate miniaturization and hydrogen production; furthermore, it has the advantages of being less demanding in terms of water quality conditions and having low cost.
