Hydrogen is an emerging clean energy source that could reduce the environmental impact of nearly every part of our daily lives. It can generate electricity, heat homes and buildings, power manufacturing and fuel transportation – all with few or zero emissions. Dominion Energy is exploring how hydrogen can help us achieve our goal of net zero emissions and also help decarbonize other industries like transportation and manufacturing.

Hydrogen 101

Advancing America's Path To Net Zero Emissions

When hydrogen is produced from wind, solar or nuclear, it generates zero greenhouse gas emissions. The only emissions are water vapor. Here are a few ways hydrogen can help Dominion Energy and other industries on our path to a clean energy future.

Natural Gas

Cleaner Natural Gas

Hydrogen can be blended with natural gas to heat homes and buildings and fuel manufacturing – and with significantly fewer emissions.

Electricity

Clean Electricity

Hydrogen can be blended with natural gas to fuel electric power stations with less emissions. 

Electricity

Renewable Storage

Renewables are not always available when our customers need electricity. Hydrogen helps by storing energy from wind and solar when it isn’t needed so customers can use it later when they do need it. 

Electricity

Clean Transportation

Hydrogen can be a zero-carbon fuel source for most forms of transportation, including passenger cars, buses and fleet vehicles.

Utah Hydrogen Blending Project

Just like blending ethanol with gasoline reduces emissions from your car, blending clean hydrogen with natural gas reduces emissions from your home.

We’re getting started with three pilot projects that are testing a 5% hydrogen blend at our training facilities in Utah, North Carolina, and Ohio. This will help us learn how clean hydrogen works in our system and with gas appliances before we begin blending for our customers’ homes and businesses.

We successfully completed the first phase of our Utah pilot in 2021 and will begin the next phase of blending hydrogen into the system that serves our customers in Delta, Utah in 2023. The first phase of our North Carolina and Ohio blending pilots began in the summer of 2022.

How Does It Work?

There are different ways to produce hydrogen. “Grey” and “blue” hydrogen are the most commonly used today and involve some emissions. As Dominion Energy develops more wind and solar, and continues relying on zero-carbon nuclear, we will increasingly use a process known as electrolysis, which results in zero emissions.

Step 1

1. Renewables

Wind, solar and nuclear energy produce zero-carbon electricity. Some days, they produce more than consumers need.

Step 2

2. Electrolysis

This excess energy is used to power a simple process called electrolysis, which separates water (H20) into hydrogen (H2) and oxygen (O).

Step 3

3. Storage

Once the hydrogen is produced, it is safely stored until it is needed.

Step 4

4. Distribution

Hydrogen is then blended with natural gas to heat buildings or produce electricity, or to fuel transportation and manufacturing.
