Harnessing the world’s most abundant element for clean, renewable energy.
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.
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.
Cleaner Natural Gas
Hydrogen can be blended with natural gas to heat homes and buildings and fuel manufacturing – and with significantly fewer emissions.
Clean Electricity
Blending hydrogen into our natural gas power plants can help reduce emissions while producing electricity with the same reliability as natural gas.
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 we can use it later when it is.
Clean Transportation
Hydrogen can be a zero-carbon fuel source for most forms of transportation, including passenger cars, buses and fleet vehicles.
When exploring any new technology, it’s best to start small and then scale up as we gain experience.
Beginning in Spring 2021, our ThermH2TM pilot project will be underway at our Training Academy in Utah. We will blend 5% hydrogen in a test gas distribution system so we can learn how hydrogen works before blending it into the larger system that serves our customers.
Testing will conclude in June 2021 and will help us develop the knowledge and best practices we need to blend hydrogen into the broader system.
Hydrogen is the “Swiss Army knife” of clean energy. Here’s what it can do – all with few or zero emissions.

Renewable Storage
Heating
Transportation
Manufacturing
Cooking
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.
Wind, solar and nuclear energy produce zero-carbon electricity. Some days, they produce more than consumers need.
This excess energy is used to power a simple process called electrolysis, which separates water (H20) into hydrogen (H2) and oxygen (O).
Once the hydrogen is produced, it is safely stored until it is needed.
Hydrogen is then blended with natural gas to heat buildings or produce electricity, or to fuel transportation and manufacturing.
Dominion Energy is an anchor sponsor of this 5-year, $100 million research and development initiative that is focused on advancing the use of hydrogen technology across the economy.
Dominion Energy is a proud supporter of this non-profit that focuses on the use of green hydrogen in all sectors where it can accelerate the transition to a carbon-free energy system.
Dominion Energy is a long-standing member of this advocacy organization that focuses on the commercialization of hydrogen and fuel cells in the energy and transportation sectors.
