JFE Steel, a prominent Japanese steelmaker, has partnered with Exxon Mobil in a groundbreaking collaboration to develop high-pressure hydrogen pipeline technology. The aim is to shape industry standards and address the anticipated increase in demand for hydrogen in the United States. High-pressure pipelines have the capacity to transport significant quantities of hydrogen over long distances, and the JFE-Exxon pipeline is expected to withstand pressures of up to 20 megapascals, a feat that has not been achieved before.The joint project between JFE Steel and Exxon Mobil is set to begin this autumn at JFE's research facility in Chiba, Japan. The focus will be on collecting data on material strength by installing an electric resistance welded steel pipe with 2-centimeter walls and a diameter of 41 cm in a testing apparatus. The objective is to develop durable materials that can withstand the brittleness caused by hydrogen and operate under high-pressure conditions. Once the technology is developed, Exxon will seek certification under U.S. industrial standards.Currently, the lack of established standards and testing methods has hindered the progress of product development in this field. JFE Steel aims to determine the optimal diameter and thickness for high-pressure pipelines, potentially enabling commercialization within a year or two. The research and development expenses for the project in fiscal year 2023 will be approximately 25 million yen, with support from the nonprofit organization Nippon Foundation based in Tokyo.Exxon Mobil, as part of its clean energy initiatives, is considering the construction of one of the world's largest clean hydrogen plants in Texas. The plant would capture carbon dioxide emissions generated during hydrogen production from natural gas. With the projected increase in global clean hydrogen production, the collaboration between JFE Steel and Exxon Mobil positions them to play a significant role in meeting the growing demand for hydrogen.The utilization of high-pressure pipelines is crucial for transporting hydrogen from production sites to remote power plants and factories, supporting the decarbonization efforts outlined by U.S. President Joe Biden. The U.S. Environmental Protection Agency has proposed regulations requiring gas-fired power plants to co-fire with hydrogen, further highlighting the need for efficient hydrogen transportation infrastructure.JFE Steel's expertise in corrosion-resistant steel pipes and their successful track record in offshore oil fields make them a leading player in the industry. The company's pipelines, known for their resistance to extremely low temperatures, have also been utilized in resource development projects in Alaska.
