As the world accelerates toward a carbon-neutral future, hydrogen energy has emerged as a cornerstone of clean energy systems. From production and storage to transportation and utilization, the hydrogen energy value chain presents numerous technical and economic challenges. Graphene, with its extraordinary physical, chemical, and mechanical properties, offers transformative solutions across these critical segments. This article explores graphene’s applications in the hydrogen energy industry and analyzes its market potential.

Hydrogen Energy Value Chain Overview

The hydrogen energy industry consists of several interconnected stages:

1. Hydrogen Production – Generating hydrogen through methods like electrolysis, natural gas reforming, or biomass gasification.
2. Hydrogen Storage – Storing hydrogen in gaseous, liquid, or solid forms for safe and efficient distribution.
3. Hydrogen Transportation – Moving hydrogen via pipelines, tankers, or hydrogen carriers.
4. Hydrogen Utilization – Using hydrogen in fuel cells, industrial processes, and energy generation.

Each of these segments requires materials and technologies to address efficiency, cost, and scalability challenges. Graphene’s multifunctional capabilities make it a key enabler in optimizing the hydrogen value chain.

Graphene Applications in the Hydrogen Energy Industry

1. Graphene in Hydrogen Production

Graphene enhances hydrogen production by improving the performance and durability of catalysts and electrodes used in electrolysis systems.

• Electrolysis Efficiency: Graphene-based electrodes with high electrical conductivity and chemical stability reduce energy consumption during water electrolysis. Functionalized graphene composites, such as graphene with platinum or nickel catalysts, improve hydrogen evolution reaction (HER) kinetics.Example: Graphene-supported iridium catalysts in proton exchange membrane (PEM) electrolysis systems exhibit reduced noble metal usage while maintaining high catalytic activity.
• Seawater Electrolysis: Graphene’s corrosion resistance makes it suitable for seawater electrolysis, a promising solution to overcome freshwater scarcity.

2. Graphene in Hydrogen Storage

Efficient storage is a major challenge in hydrogen energy. Graphene-based materials, particularly porous graphene structures, enhance hydrogen adsorption and desorption performance.

• Graphene-Based Nanoporous Materials: Graphene’s high surface area and tunable porosity enable significant hydrogen adsorption through physical and chemical interactions. Doped graphene (with elements like boron or nitrogen) further enhances binding energy with hydrogen molecules.Example: Graphene aerogels and graphene-metal organic framework (MOF) composites exhibit superior hydrogen storage capacities at ambient conditions compared to traditional materials.
• Solid-State Storage: Graphene enhances the hydrogen uptake and release properties of metal hydrides by acting as a stabilizing matrix.

3. Graphene in Hydrogen Transportation

Hydrogen transportation systems require materials with high mechanical strength, chemical resistance, and leak-proof properties.

• Composite Pipelines: Graphene-reinforced polymer composites offer lightweight, durable, and corrosion-resistant solutions for hydrogen pipelines.
• Hydrogen Carriers: Graphene-based materials are being explored as potential carriers for reversible hydrogen adsorption and release, enabling safer and more efficient transportation.

4. Graphene in Hydrogen Utilization

Graphene plays a pivotal role in fuel cells, a critical technology for converting hydrogen into electricity.

• Fuel Cell Catalysts: Graphene supports for platinum catalysts in proton exchange membrane fuel cells (PEMFCs) enhance catalytic activity and reduce the amount of expensive platinum required.Example: Reduced graphene oxide (rGO) combined with platinum nanoparticles demonstrates higher durability and performance in PEMFCs compared to conventional carbon black supports.
• Durable Electrodes: Graphene’s mechanical stability and corrosion resistance extend the lifespan of fuel cell components.
• Sensors: Graphene-based hydrogen sensors ensure the safe operation of hydrogen-powered systems by detecting leaks with high sensitivity and rapid response.
