News Release (June 28, 2024)
TOYO GLASS’s proposed glass melting furnace with an on-sitehydrogen supply facility has been selected as a NEDO project.
TOYO GLASS CO., LTD. (“Toyo Glass”), a consolidated subsidiary of Toyo Seikan Group Holdings,
Ltd., has been selected to participate in the 2024 Regional Hydrogen Utilization Technology
Development section of the New Energy and Industrial Technology Development Organization’s(NEDO) Development of Technologies for Realizing a Hydrogen Society project, with its proposal forthe development of a glass melting furnace equipped with an on-site hydrogen supply facility. This isToyo Glass’s second NEDO project related to hydrogen utilization, following its Research andDevelopment of the Utilization of an Oxygen–Hydrogen Combustion Flame as the Heat Source forSoda-Lime Glass Melting proposal, which was selected in June 2023 as“Technology Development
Project for the Construction of a Competitive Hydrogen Supply Chain/ Comprehensive Survey andResearch/ Survey and Research on the Application of Oxygen and Hydrogen Combustion Technologyto Heat Demand”.
Glass melting furnaces typically rely on large amounts of fossil fuels, but achieving a decarbonizedsociety will ultimately require a transition to non-fossil fuels, such as hydrogen. To facilitate a transition
to using hydrogen as a fuel, it is first necessary to establish a hydrogen supply system. Toyo Glass
therefore seeks to contribute to the utilization of hydrogen energy in the region by creating an on-sitehydrogen supply facility.
If the glass melting furnaces owned by Toyo Glass were converted to hydrogen, over 6,000 largehydrogen trailers would be needed annually for each furnace. However, obtaining such a large amountof hydrogen from external sources would pose challenges, such as constructing multiple large storage
tanks on factory premises and the consequent requirements for stringent safety management of highpressure and liquefied hydrogen.
Water electrolysis involves passing an electric current through water (H2O) to separate it into oxygen(O2) and hydrogen (H2). Constructing an on-site hydrogen supply facility that uses electrolysis would
make it possible to produce hydrogen according to demand using existing water and electricity sources,
eliminating the need for large storage facilities. Additionally, as a glass melting furnace requires only
the pressure necessary for combustion, there is no need to compress or liquefy hydrogen, making iteasier to introduce. Furthermore, if the electricity needed for electrolysis is supplied from local
renewable energy generation facilities, this could lead to the development of a regionally self-sufficienthydrogen energy utilization system.
In this project, a bench-scale model of the facility will be created, and technology will be developedtoward its future implementation in glass melting furnaces. As a leading company in the glass bottle
industry, Toyo Glass is committed to creating glass melting furnaces that utilize hydrogen energy andthus have minimal environmental impact while continuing to manufacture high-quality glass bottles thatmeet customers’ expectations.
