Delta was selected for several reasons:

• Starting small: The customer base and system size/configuration
• Modern system: The community has a modern natural gas system
• Proximity: Delta is close to renewable energy resources and future hydrogen projects

Delta is uniquely positioned to be a leader in this emerging area of energy innovation.

1. Hydrogen Starts Here
2. Control system uses flow information from meter set to determine how much hydrogen to add
3. Hydrogen is added here based on demand
4. Gas chromatograph double checks that hydrogen amount is correct
5. Blended hydrogen travels underground into the Delta system

Customers will continue to receive safe, reliable, and affordable service that will include the environmental benefits of hydrogen blending with traditional natural gas.

Bills will not increase as a result of hydrogen blending. No appliance or equipment changes will be required and appliance performance won’t be impacted.

The demand for clean, renewable energy is growing. Hydrogen is an emerging clean energy source that could reduce the environmental impact of nearly every part of our daily lives. Just like blending ethanol with gasoline in your car, blending hydrogen with natural gas lowers emissions.

Dominion Energy is exploring how hydrogen can help us achieve our goal of net zero emissions and also help decarbonize other industries.

Hydrogen: The Next Frontier Of Clean Energy

• Appliance Compatibility: Appliances operated normally and safely.
• Pipeline Material Safety: No impact to the integrity of existing gas distribution infrastructure. 
• Emissions Reduction: Lower carbon emissions and no increase in other key emissions.
• Leak Detection Technologies: Odorant, which is added to natural gas to allow for detection, was 
  unaffected. In addition, industry-standard leak detection equipment was unaffected. 
• Natural Gas Quality Impacts: No change to quality or heating value of the natural gas
