SPP and Member Utilities Successfully Achieve Western Expansion Milestone

LCG, April 2, 2026--Southwest Power Pool (SPP) today announced that the expansion of its service territory into the Western Interconnection has been a success. The milestone makes SPP the first regional transmission organization (RTO) with services spanning the Eastern and Western Interconnections. Its member organizations, which cover all or part of 17 states, can now benefit from a more operationally and geographically diverse integrated system.

Vault 44.01 Receives EPA Class VI Permit Approval for CCS Project in Indiana

LCG, April 9, 2026--Vault 44.01 Ltd. (Vault) announced today that the U.S. Environmental Protection Agency (EPA) Region 5 has issued a final Underground Injection Control (UIC) Class VI permit for the One Carbon Partnership CCS project (the "OCP Project") near Union City, Indiana. The One Carbon Partnership is a joint venture between Cardinal Ethanol and Vault.

Class VI wells are used to inject carbon dioxide (CO2) into underground formations to sequester CO2 and reduce CO2 emissions to the atmosphere. The UIC Program, developed to protect Underground Sources of Drinking Water (or USDWs), may be directly implemented by the EPA regional offices or by states, which then regulate the injection of fluids (e.g., CO2, water, wastewater, brines from oil and gas production) into the subsurface for the purposes of storage or disposal.

Vault states that the OCP Project represents a capital investment of over $60 million in Randolph County, Indiana and will bolster the local agricultural economy by providing corn growers with access to the growing low-carbon ethanol market. Once operational, the OCP Project will capture and permanently store up to 450,000 metric tons of CO2 annually, with sufficient pore space to safely inject approximately 13.5 million metric tons over 30 years.

Vault pursues the development of actionable CCS (carbon capture and storage) projects in partnership with high quality industrial businesses and has over a dozen projects in the US Midwest, US Gulf Coast, and Canada in various stages of development. Vault anticipates projects to come onstream promptly upon receipt of Class VI Permits from the EPA.

Vault's President and CEO stated, "This is a defining moment for Vault and Cardinal Ethanol and a powerful validation of Vault's technical expertise, commitment to stakeholder engagement, and disciplined approach to project execution. We have developed our company with a core objective of advancing the CCS industry in partnership with business, community, government, and capital partners, and with EPA's recent approval, we are excited to build our first project in Indiana. We are particularly grateful to our partners at Cardinal for their support and commitment to our shared vision for this project."

The Chairman of Cardinal Ethanol's Board of Directors said, "Cardinal Ethanol remains committed to improving our world by continuously reducing our carbon footprint and maintaining the highest standards of operational excellence. The EPA's approval underscores our project's soundness, its community support, and reinforces our commitment to value creation for our owners and neighbors. Together with Vault, we are taking an important step toward a zero-emission liquid fuel solution."

"Indiana has a large number of industrial and power facilities that could be suitable for carbon capture and storage under the right technical and economic conditions," said a carbon management research manager at the Great Plains Institute last year. "Over 99% of CO2 emissions in the state are emitted by the 146 facilities that are eligible for the 45Q tax credit and span a number of industrial and power sectors, including cement, ethanol, and steel facilities, which have CO2 emissions intrinsic to their processes and will likely need carbon capture to fully decarbonize."

Vault believes that it is advancing an industry-leading portfolio of CCS projects with ethanol industry partners to deliver CO2 emissions reductions that provide economic benefits to local farmers, communities, and Vault's ethanol partners. Vault states that its pipeline currently includes 10 projects spanning five states. With its CCS experience and core projects in the ethanol industry, Vault states that it is actively pursuing new sectors, with projects in development including decarbonized baseload power, hydrogen, cement, and fiber-based manufacturing.
