Production via Electrolysis 

This area focuses on best practices for high, intermediate, and low temperature electrolysis processes, standard operating procedures and balance of plant operations, including: 

• Water purification standards 
• Interconnections with power electronics, storage, or distribution hardware 
• Standard assessment practices for system reliability and risk 

Production via Non-Electrolysis Pathways

This area evaluates the use of alternate hydrogen production systems, including:

• Renewable methane and biogenic pathways involving feedstock like woody biomass, municipal waste, and wastewater 
• Thermal pathways like gasification and pyrolysis

Distribution and Storage

This area focuses on the high-potential pathways to storage and distribution as identified in the Pathways to Commercial Liftoff Report, including:

• Gas and liquid hydrogen storage 
• Geologic storage 
• Distribution pipelines and networks

Transportation Applications

This area focuses on direct hydrogen use in transportation, including: 

• Fuel cells and internal-combustion engines 
• Vehicles (trucking, rail, shipping) and their infrastructure 
• Standardization of stations (nozzles, compression, delivery and storage methods)
• Shared balance of station components and procedures (e.g. leak detection)

Derivatives and Transformations

This area will focus on technologies related to near-term hydrogen derivative fuels and products like ammonia and methanol, and their possible applications in aviation, maritime and other industries.

Heating, Power and other Industrial Applications

This area will focus on markets, regions, and applications where hydrogen is a viable solution for power and industrial heat compared to electricity or synthetic natural gas. This includes, but is not limited to: 

• Displacing natural gas through hydrogen combustion in turbines (peaking power and intermediate range capacity factor)
• Fuel cells for power applications (firm power source, grid resilience)
• Residential heating (<300 C) decarbonization options
• High-temperature industrial process heat decarbonization (>300 C) (Iron, Steel, etc.)
