Hydrogen offers a sustainable solution to the energy crisis by utilizing agricultural waste for biohydrogen production. This renewable energy source enhances crop growth, soil health, and livestock reproduction, creating a circular agricultural ecosystem.
Area of Science:
- Agricultural Science
- Renewable Energy
- Environmental Science
Background:
- Fossil fuel dependence causes resource depletion and greenhouse gas emissions, worsening climate change.
- Hydrogen presents a sustainable, high-energy-density alternative with environmentally friendly combustion.
- Agriculture can leverage hydrogen for production, storage, and application to mitigate energy challenges and waste.
Purpose of the Study:
- To explore the latest research on hydrogen production, storage, and utilization in agriculture.
- To provide insights into achieving carbon neutrality through the hydrogen cycle in agriculture.
- To guide the development of sustainable agricultural practices via hydrogen technology.
Main Methods:
- Review of current research on biohydrogen production from agricultural waste.
- Analysis of hydrogen storage mechanisms, including crop-growth-stimulating carriers.
- Examination of hydrogen applications in agriculture, focusing on soil, crops, and livestock.
Main Results:
- Conversion of agricultural waste to biohydrogen addresses energy needs and waste management.
- Novel hydrogen carriers improve storage efficiency, crop yield, and stress resistance.
- Hydrogen application benefits soil microorganisms, crop growth, and livestock reproduction.
Conclusions:
- Hydrogen integration in agriculture fosters a self-sustaining, low-carbon circular ecosystem.
- The hydrogen cycle offers a pathway to carbon neutrality and sustainable agricultural development.
- Further research and practical guidance are needed to optimize hydrogen's role in agriculture.

Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.
The hydrogenation process takes place on the...
