Hydrogen is a key piece of our plan to reach our goal of delivering carbon neutral energy by 2050. It’s a versatile energy source that can do many of the jobs natural gas does today but with less of a climate impact. In fact, it emits no carbon emissions when burned and can be blended with natural gas into existing pipelines, distributed in a dedicated pipe network, or combined with waste carbon dioxide and converted to synthetic natural gas.[1]https://www.hydrogen.energy.gov/docs/hydrogenprogramlibraries/pdfs/us-national-clean-hydrogen-strategy-roadmap.pdf?Status=Master
We see unprecedented opportunities in the future for bringing hydrogen into our energy mix at a large scale and we are working hard on a variety of options to help our customers decarbonize. Emerging technologies can also play a role in decarbonizing non-renewable gas supplies through the direct capture of carbon dioxide at the point of combustion. These emissions can be sequestered or utilized, giving rise to the category of carbon capture, utilization, and storage (CCUS).
What is hydrogen?
Hydrogen is an odorless and colorless chemical element. Though abundant, hydrogen does not exist independently in nature and therefore is produced from various energy sources and methods.[2]https://www.nrel.gov/research/eds-hydrogen.html
A growing amount of gas utilities in North America, the United Kingdom and Europe have started to blend hydrogen into portions of their distribution systems to demonstrate its viability as an emissions reduction solution.
Outside research and company field tests show that blends upwards of 20% hydrogen are compatible with existing natural gas infrastructure and appliances.[3]Examples of research include, https://www.nrel.gov/docs/fy13osti/51995.pdf; Glanville P, Fridlyand A, Sutherland B, Liszka M, Zhao Y, Bingham L, Jorgensen K.

Our hydrogen and carbon capture projects
Starting with our own facility
Starting with our own facility
We have been successfully blending hydrogen at our largest facility for more than two years, starting out at 5% and now blending 20% hydrogen directly into our pipes to test our distribution system materials, leak detection equipment and to ensure normal operations of end uses, including furnaces, water heaters, fireplaces, and cooktops.Hydrogen projects underway around the globe
More than a dozen North American utilities are actively working on hydrogen as a resource. Some are already safely delivering hydrogen-blended gas to customers, such as Enbridge Gas, New Jersey Natural Gas, and CenterPoint Energy, and others are advancing pure research and development, like SoCalGas, who is developing a clean hydrogen home.[6]/https://newsroom.socalgas.com/press-release/socalgas-successfully-tests-microgrid-demonstration-project-in-downey
The HyDeploy consortium in the UK is demonstrating the potential for hydrogen blends of up to 20%, beginning with a Keele University project (2019-2021) that achieved a 15% blend delivered to ~100 buildings. The success of the Keele University project led to the second phase which successfully expanded delivery to a 650-home project. Now, HyDeploy is working on its submission to the UK Government for final approval of the use of hydrogen blending across the gas distribution network.[7]/https://hydeploy.co.uk/project-phases/#phase-1-keele
In Italy, the largest gas utility, SNAM, successfully ran a trial blend of 5% and then 10% in sections of its pipelines system.[8]https://www.bakerhughes.com/company/news/snam-and-baker-hughes-successfully-complete-first-trial-use-hydrogen-fuel-gasTheir work continues.
