The Tokyo Institute of Technology has recently secured a patent for a groundbreaking method for enhancing hydrogen storage and transportation. This patent addresses the pivotal need for efficient and safe hydrogen management, a barrier to the wider adoption of hydrogen as a clean energy source. The patented technology revolves around a boron, hydrogen, and oxygen structure characterized by B—H—B, B—H, and B—OH bonds. The innovation leverages these bonds in a unique configuration, ensured by specific transmittance values in Fourier-transform infrared spectroscopy (FT-IR). The formulas specifying these transmittance values are: 1. \( 0.80 \leq \frac{a}{c} \leq 0.96 \)2. \( 0.95 \leq…

The Polish Ministry of Infrastructure has recently issued a tender titled “Construction of a Bus Depot and Accompanying Infrastructure, Including a Hydrogen Refueling Station.” Published on September 2, 2024, this tender invites construction companies to submit their proposals by October 1, 2024. The initiative marks a significant step toward advancing hydrogen infrastructure in Poland, demonstrating the country’s commitment to sustainable public transportation solutions. The primary objectives of the tender are twofold: to build a modern bus depot and establish a hydrogen refueling station capable of supporting the infrastructure needs of hydrogen-powered public transport. This project is set to enhance Poland’s…

Hydrogen has enormous potential as a carbon-free energy source. Countries such as Australia, Namibia, and Patagonia are among the areas where plans are underway to build more than 1,600 plants to produce hydrogen using electricity from the sun or wind. Despite this enthusiasm, almost no one is buying green hydrogen. Lack of Purchase Most green hydrogen projects do not have purchase contracts. Even when contracts exist, they are non-binding and can be terminated. Only 12% of hydrogen installations have customers with actual purchase agreements. Problems with Funding Developers and bankers do not dare to invest without sure buyers. Hydrogen production…

A recent study published in the International Journal of Hydrogen Energy introduces a novel optimization framework to enhance the capacity planning of hydrogen-based residential energy hubs. The research by Alireza Ghasemloo, Aref Kazemi, and Moein Moeini-Aghtaie proposes a comprehensive model highlighting the potential of hydrogen within renewable energy hub systems. The hydrogen industry continuously evolves, with increasing attention to decentralized energy solutions. Distributed Energy Resources (DERs) have been pivotal in modernizing energy networks, promoting more efficient thermodynamic processes, and reducing transmission losses. The study’s relevance is underscored by its focus on integrating hydrogen technologies within these systems, addressing the growing…

A recent study published in the International Journal of Hydrogen Energy by Xin Yang, Wen Wang, Zhao Wang, and Fanhua Ma investigates the optimization of pre-cooling processes in high-pressure hydrogen refueling stations (HRS). The study, in the journal’s October 2024 issue, presents a novel simulation model to enhance the efficiency and safety of hydrogen refueling operations. With hydrogen fuel cell vehicles (FCVs) being a promising solution to reduce greenhouse gas emissions, developing effective and safe hydrogen refueling stations is crucial. The study is particularly relevant as it addresses the thermal management challenges in refueling stations that employ 70 MPa hydrogen…

The governments of Brazil and Germany are exploring the creation of a green hydrogen hub in Cubatão (SP), a city once deemed the world’s most polluted by the United Nations. This hub aims to foster joint actions among local industries to produce green supplies powered by renewable energy sources. Historical Pollution Context During the 1980s, Cubatão’s industries released approximately a thousand tons of pollutants into the atmosphere daily. Historian Welington Ribeiro Borges noted that this substantial pollution earned the city’s title of ‘Death Valley’ and the infamous recognition as the most polluted city globally by the UN. Environmental degradation affected…

Rust as an Energy Storage: A method for long-term storage of H2 is inspired by the centuries-old steam-iron process. Researchers at ETH Zurich have developed a promising method for the seasonal storage of renewable energy: They utilize ordinary iron oxide, also known as rust, to efficiently and cost-effectively store hydrogen. The technology, inspired by the centuries-old steam-iron process, could fundamentally change how we use renewable energy. Excess solar power in summer is used to split water into hydrogen. This hydrogen reacts in simple stainless-steel containers with iron ore, leaving pure iron. In winter, the hydrogen is released by adding steam…

With the global push for more sustainable energy solutions, green hydrogen has become a significant area of focus. Storing this hydrogen efficiently remains a critical challenge. Introducing the innovative concept of a cryogenic flux capacitor as a potential solution. Cryogenic Flux Capacitor Basics A cryogenic flux capacitor is a theoretical device envisioned to store hydrogen at extremely low temperatures, increasing its density and making storage more efficient. The device could operate at cryogenic temperatures (-150°C to -273°C), where hydrogen exists in a liquid or solid state. This method would significantly reduce storage volumes compared to traditional methods. Techno-Economic Analysis 1.…
