GrafTech and Antora Energy Partner to Power American Industry with Carbon

ST. MARYS, Pa.–(BUSINESS WIRE)–GrafTech International Ltd. (NYSE: EAF) (“GrafTech”) and Antora Energy (“Antora”) today announced a strategic collaboration to develop and supply carbon-based materials for Antora’s thermal batteries, strengthening the domestic manufacturing base for American energy technology.

Antora’s thermal batteries store energy using carbon—the same material that has been produced in St. Marys, Pennsylvania for generations. Together, Antora and GrafTech will develop carbon-based materials at GrafTech’s St. Marys facility for use in Antora’s battery modules, which help lower energy costs and make American factories more competitive.

The collaboration is already creating jobs in St. Marys, where GrafTech has restarted eight bake furnaces. Antora and GrafTech have hired new workers in St. Marys and are hiring a dozen more across plant operations, machining, maintenance, and a range of additional functions.

“St. Marys has been an important part of GrafTech’s manufacturing footprint since we acquired the facility in 2010, and we are proud to partner with Antora to leverage the facility and our nearly 140 years of experience in carbon and synthetic graphite-based solutions,” said Timothy Flanagan, Chief Executive Officer and President, GrafTech International Ltd. “This partnership is expected to utilize a significant portion of the bake furnace capacity at St. Marys, creating an important new application for the facility while diversifying our end markets and supporting the growth of the domestic energy storage supply chain. We are particularly pleased that this opportunity builds on the skills and experience of the St. Marys workforce, and we look forward to growing our commercial relationship with Antora.”

“By partnering with GrafTech to source carbon-based materials from their St. Marys facility, Antora is strengthening our domestic supply chain,” said Andrew Ponec, Co-Founder and CEO, Antora Energy. “GrafTech is a leading Pennsylvania manufacturer, and we’re excited to work with them to deliver affordable and reliable energy across the country. This is an investment in America’s energy leadership.”

Antora’s thermal batteries store low-cost electricity as heat in insulated blocks of solid carbon. This heat is then delivered around-the-clock as heat or electricity. The same factory-built modules can serve a chemical plant, a food producer, a steelmaker, a data center, or the grid, without supply-constrained critical minerals or multi-year construction timelines.

Carbon has been made in the United States for centuries, and is today widely used across steelmaking, aluminum production, and fireproofing applications. The carbon blocks and insulation in Antora’s thermal batteries are made by heating lower-purity carbon feedstocks—such as petroleum coke and coal tar pitch—in high-temperature furnaces. As the industry scales, thermal energy storage has the potential to create major new markets for U.S. petroleum and coal byproducts.

“This partnership builds upon the skilled workforce, infrastructure, and industrial experience that has made Pennsylvania a leader in our country’s energy future,” said Rep. Glenn “GT” Thompson (PA-15). “GrafTech and Antora are creating good jobs in the commonwealth while helping build a domestic supply chain that supports American manufacturing and energy security. I’m proud to see this investment made in Elk County.”

This partnership comes on the heels of Antora’s oversubscribed $550 million Series C in late July of this year. In May, Antora announced the commissioning of Project Big Stone, one of the largest battery storage systems in the world. The project is already delivering affordable, round-the-clock energy to POET, the world’s largest producer of biofuels, at their Big Stone City, South Dakota facility.

A Memorandum of Understanding is in place, and the parties intend to negotiate and execute definitive documentation regarding the strategic collaboration. The final agreements remain subject to negotiated terms and conditions.
