GECST

Green Energy Conversion and Storage Technologies (GECST) is an early-stage applied engineering initiative focused on metal-based pathways for renewable energy conversion, hydrogen generation, long-duration energy storage, and clean industrial heat.GECST explores the use of recyclable metals, particularly iron-based materials, as solid energy carriers that can interact with water, air, oxygen, hydrogen, or steam in controlled thermochemical processes. A key area of interest is hydrogen generation via metal–water reactions, in which reactive metals can produce hydrogen from water while being converted to metal oxides. This concept may offer a complementary route for decentralized, on-demand, backup, or site-integrated hydrogen generation, especially in applications where compact solid energy carriers, safer storage, and flexible hydrogen availability are valuable. In parallel, GECST studies the regeneration of metal oxides back to reduced metals using low-carbon pathways, including hydrogen-based reduction, electrochemical routes, and other renewable-energy-driven processes. This creates the basis for a circular metal/metal-oxide loop in which hydrogen is not only a product, but also a strategic enabler for closing the energy-carrier cycle. Beyond hydrogen production, GECST investigates iron-air and metal-air reactions for oxygen removal, nitrogen-rich gas generation, and high-temperature heat release. These concepts may have potential relevance to industrial decarbonization, inerting and purging, controlled atmospheres, process safety, and hard-to-electrify thermal applications.GECST is not positioned as a conventional electrolyzer, fuel-cell, or compressed-hydrogen company. Instead, it aims to develop complementary technologies at the interface of hydrogen, solid energy carriers, industrial heat, gas management, and long-duration renewable energy storage. The current focus is on feasibility assessment, reaction-system design, mass and energy balances, safety evaluation, techno-economic analysis, and pilot-oriented development. By combining founder know-how, published scientific foundations, applied engineering, and potential collaboration with industrial and research partners, GECST seeks to contribute to a future hydrogen ecosystem in which renewable energy can be stored, transported, converted, and used through safer, recyclable, and industrially compatible solid materials.
