As hydrogen is an integral part of the transition to clean energy, the reliable supply of hydrogen at scale required to support this transition is critical. The hydrogen supply chain should address not only the scale issues, but also should be sustainable (with low carbon footprint) and commercially affordable. This session will address the topics related to ensuring the hydrogen supply for clean energy transition.

• Biological hydrogen production
• Biomass and waste conversion
• Direct hydrogen carrier production
• Electrolysis
• Fossil fuel conversion
• Natural hydrogen
• Photochemical and photocatalytic processes/li>
• Thermal water splitting
• Separation materials and technologies

Establishing large-scale hydrogen energy value chains depends on the cost and efficiency of hydrogen storage and transport. This session will explore technological solutions for storage of hydrogen at various scales and applications, such as for grid stabilisation, seasonal energy storage, or long-distance transportation.

• Liquid hydrogen
• Ammonia
• LOHCs
• Underground storage
• Pipeline storage
• Pipeline materials and performance
• Pipeline design and integrity management
• Pipeline and network operations
• Hydrogen embrittlement
• Hydrogen compression

A feature of the emergence of hydrogen energy systems is the diversity of potential application pathways and industrial sectors. Commonly described as ‘Power-to-X’, there are also opportunities for industrial sectors not traditionally associated with hydrogen to play a role in production (such as the waste sector) or utilization for decarbonization (such as agriculture). This session will explore the different ways that various industry sectors can come together to both support ‘hydrogen at scale’ as well as decarbonization of industries such as metals production

• Electricity—grid balancing & stability, grid integration, stationary fuel cells, distributed power generation, engines & turbines
• Export potential—shipping technology development, loading/offloading, infrastructure optimisation from production site to port loading site
• Gas networks and appliances—appliance testing, metering, hydrogen gas separation
• Heat storage—covers thermal batteries based on metal hydrides
• Industrial heat processes—steel, cement, metals refining, etc.
• Industrial feedstock processes—ammonia, synthetic fuels, and methanol production
• Mobility—mobile fuel cells; onboard storage; refuelling stations; bunkering: land, sea, air mobility forms; vehicle/engine improvements

Emerging of hydrogen industry also results in several questions to be addressed to support this industry. Understanding the environmental impact of large-scale hydrogen production and transport, as well as ensuring that this new industry will have a social acceptance is very important for the deployment of hydrogen-base technologies. The appropriate policies and regulations, as well as safety standards and certification processes will ensure the smooth transition. It also requires good understanding of the socio-technical risks and techno-economic evaluation of various options.

• Environmental impacts
• Safety and standards
• Public acceptance
• Socio-technical risks
• Techno-economic evaluation
• Energy systems integration
• Sector coupling
• Supply chain integration
• Policy and Regulations
• Hydrogen certification schemes
