Hydrogen
Hydrogen is the simplest and most abundant element in the universe. It is a gas but occurs primarily in combination with oxygen in water and in organic matter. There are an estimated 400 to 500 hydrogen-fueled vehicles in the US, mostly in California, that store hydrogen to power electric motors, producing almost no pollution. Pure hydrogen can combine explosively with other elements to form compounds and is used in many industrial processes like ammonia and oil production.
Fuel for today’s energy transition and the future
This document discusses different types of hydrogen production and their classifications. It also discusses the importance and potential of green hydrogen due to climate change goals and increasing renewable energy. Green hydrogen, produced through electrolysis using renewable electricity, is seen as an important storage solution for excess renewable energy and a potential replacement for fossil fuels. The document outlines some historical uses of hydrogen and fuel cells as well as current and potential future applications across sectors like transportation, power generation, and industry.
Future towards renewable hydrogen storage and powered applications
Future renewable hydrogen storage and applications rely on metal hydrides and nanomaterials. Metal hydrides can store hydrogen at low pressures and ambient temperatures, making them suitable for portable consumer products. Nanocrystalline metal hydrides exhibit faster hydrogen absorption/desorption kinetics and altered thermodynamic stability compared to bulk materials. Catalysts also help accelerate hydrogen sorption reactions in metal hydrides. Sodium borohydride is a commonly used complex hydride for hydrogen storage but requires a catalyst and produces waste that limits recyclability.
Hydrogen
The document discusses hydrogen as a fuel source. It provides background on hydrogen, including that it is the most abundant element in the universe and has been used as a fuel for decades, including by NASA for rocket fuel. The document also outlines four key benefits of hydrogen as a future fuel: it is clean burning, can be produced domestically, and is well-suited for transportation and electricity generation applications.
Physical and chemical properties of hydrogen
Hydrogen is the simplest and lightest element, composed of one proton and electron. It exists as a colorless and odorless gas that is lighter than air. Hydrogen reacts easily with oxygen to form water, making it useful as an energy medium by burning to release energy. It has the highest energy content by weight of any fuel. Some key properties include its low boiling point of -252.88°C, low density as a gas, and wide explosive range when mixed with air.
The manufacturing and storage of hydrogen
The document discusses hydrogen production and a potential hydrogen economy. It outlines that hydrogen is mainly used today in the Haber process for ammonia production and hydrocracking of petroleum. The hydrogen economy proposes using hydrogen as an energy carrier produced from water using energy rather than being an energy source itself. The main challenges to a hydrogen economy are high costs, developing efficient hydrogen storage methods, and building the necessary infrastructure including production, transportation and distribution. Current hydrogen is mainly produced via natural gas reforming, but other methods discussed are electrolysis, gasification, and biological and photolytic production.

a presentation Hydrogen energy by MUKESH RAM
Hydrogen can be used as an energy carrier but must be produced from other substances like water or fossil fuels. It is commonly extracted via electrolysis of water or steam reforming of methane. Steam reforming currently accounts for most hydrogen production but results in greenhouse gas emissions. Hydrogen fuel cells combine hydrogen and oxygen to produce electricity and water. They have potential applications to power vehicles and off-grid locations. However, widespread adoption of hydrogen energy faces challenges including high costs of production and fuel cells as well as greenhouse gas emissions associated with current production methods.

CAKE: Sharing Slices of Confidential Data on Blockchain
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.
