This document describes an invention called SHIR for storing hydrogen in coal through treatment with ionizing radiation. SHIR aims to use coal as a hydrogen absorber to create an improved fuel. It details how ionizing radiation can increase the coal's hydrogen storage capacity and lists the technical specifications and estimated costs of building a SHIR plant. The document argues that SHIR could help address issues with South Africa's coal industry and lower its greenhouse gas emissions by producing more energy from coal. It introduces the inventors, Antonio Madroñero and Pilar, and their relevant expertise in materials science and renewable energy.
