FURTHER ELECTRIFICATION OF ASSETS:

• Compression assets are vital to efficiently flowing natural gas through ONEOK’s pipelines. Electric-powered compressors produce no Scope 1 combustion emissions and provide opportunities to reduce ONEOK’s Scope 1 and Scope 2 greenhouse gas (GHG) emissions. ONEOK’s Natural Gas Gathering and Processing segment’s compression currently is nearly 70% electric, with the Rocky Mountain region’s compression more than 80% electric. In ONEOK’s Natural Gas Liquids segment, more than 95% of pump stations are electric.

 

SOURCING RENEWABLE ENERGY FOR OPERATIONS:

• ONEOK’s existing assets and extensive operations provide opportunities to take advantage of energy produced from wind and solar. We have installed solar powered equipment at some of our facilities, and ONEOK purchases electricity generated by solar, wind and other renewables from electric providers located in regions conducive to renewable energy production. Approximately 30% of the current electrical supply in the regions we operate is sourced from renewables.

 

LOW CARBON LIQUID FUELS:

• Biofuels, such as ethanol, biodiesel, renewable diesel and sustainable aviation fuel, play an important role in accelerating America’s energy transformation by providing alternative low-carbon liquid fuels. These biofuels, made from renewable feedstocks such as corn, soybeans, sugarcane, vegetable oils, recycled cooking oils and animal fats, are blended with refined products to comply with U.S. EPA renewable fuels standards.
• ONEOK’s existing infrastructure can connect renewable fuels production to major airports, railroad depots and truck racks. Our assets position us to help address the growing market demand for low-carbon liquid fuels and provide opportunities to build new infrastructure to transport and store these products.

HYDROGEN:

• Midstream service providers will be needed to transport and store low-carbon hydrogen, provide connectivity between production and demand centers, and potentially help export hydrogen or hydrogen derivatives to international markets. Low-carbon hydrogen development is still in early stages, but as the technology and markets develop, we recognize the importance of providing hydrogen-related solutions to current and future customers. Examples of our hydrogen-related activities include:

 

• • Regional Clean Hydrogen Hubs – We provided Letters of Support for two hydrogen hubs that were selected in 2023 for funding by the Department of Energy (DOE). The HyVelocity hub centers on Houston, Texas, and the U.S. Gulf Coast. The Heartland Hydrogen Hub includes projects to produce low-carbon hydrogen across Montana, North Dakota, South Dakota, Minnesota and Wisconsin. Both hub awardees include areas where ONEOK has extensive operations, and as projects develop, we will evaluate opportunities to participate.

  • H2@Scale Texas and Beyond –Part of the DOE’s larger H2@Scale initiative to advance affordable hydrogen production, storage, distribution and use across multiple industry sectors. H2@Scale’s focus includes renewable hydrogen generation, vehicle fueling, market demand and economic analysis, and a study to determine the effects of hydrogen blending in natural gas pipelines.

  • Developing and Investigating Subsurface Storage Potential and Technical Challenges for Hydrogen (DISSPATCH H2) – ONEOK is a funding partner on a study, led by GTI Energy, to evaluate the potential for underground hydrogen storage in the Anadarko Basin in Oklahoma. A hydrogen economy will require large amounts of storage to accommodate fluctuations in demand, and as a partner in this study, ONEOK is providing insights from our underground storage engineering team based on our experience with natural gas storage in the state.

 

CARBON CAPTURE, UTILIZATION AND STORAGE (CCUS) OPPORTUNITIES:

• We are evaluating opportunities to capture CO₂ from our operations and either sequester it permanently underground or use it to produce more valuable products. As CCUS technologies continue to advance, we will evaluate our operating assets for opportunities to further reduce CO₂ emissions.
• We are also evaluating CCUS projects as part of the energy transformation. As a midstream service provider, we are evaluating opportunities to capture, transport and store CO₂ for existing and new customers that need those services. Examples of these projects include:

 

• • Roughrider CO₂ Storage Hub – We partnered with the Energy and Environmental Research Center to complete a feasibility study for large-scale CO₂ sequestration in North Dakota that is expected to be completed in 2026.
  • CUSP Midstream Operator Storage of CO₂ – We partnered with the Kansas Geological Survey to complete a feasibility study for CO₂ sequestration around our midstream assets in Kansas. The study will evaluate the geologic potential to store CO₂ from our existing operations and other potential sources. This project was also partially funded by the DOE and includes contributions from several of the DOE’s National Laboratories.

 

NATURAL GAS INFRASTRUCTURE INNOVATION

• We recognize the importance of using natural gas infrastructure to accelerate the energy transformation. The U.S. has an extensive network of natural gas gathering, transmission and distribution assets that provide fuel for our communities. We are participating in several studies and initiatives to explore how these assets can contribute to the energy transformation.

 

• • Pipeline Blending Cooperative Research and Development Agreement (CRADA) – A HyBlend Project – A DOE Initiative to research opportunities for hydrogen blending in natural gas infrastructure. The project includes more than 20 energy industry participants, national labs and academic institutions. Focus areas of the study include materials compatibility research, hydrogen life-cycle emissions analysis and evaluation of the economic performance of technology.
  • GTI Energy Net Zero Infrastructure Program – A GTI Energy-led consortium made up of academia, industry, environmental non-governmental organizations (NGOs) and technical experts working together to determine the most practical opportunities for integrating low-carbon solutions within the current natural gas infrastructure.
  • Renewable Natural Gas (RNG) – Natural gas produced from landfills, wastewater treatment and agricultural sources is a “drop-in” alternative to fossil fuel natural gas. We are supportive of the development of this industry and the low-carbon alternative it presents. We will continue to use our existing infrastructure to connect RNG production sites and facilitate the movement of RNG to markets and users on our system.
