FT - Can hydrogen help the world reach net zero? 14062023

The global push for net zero carbon emissions is one of humanity's greatest challenges. In this film, the FT's Simon Mundy explores how hydrogen - the lightest, most abundant element in the universe - could play a crucial role. From southern Spain to Swedish Lapland, we meet those at the forefront of this fast-growing space - all seeking a share of the billions to be made in the emerging hydrogen economy.

Matallurgy Data - Steel Making and Casting (Principles of Metallurgy), 12112020

Steel making is the first step in getting steel into a useful form. After steel making, casting in a foundry enables a steel producer to get the steel into a useful form. This can be done via sand casting in the foundry or in the melt shop via ingot casting or continuous casting. This video takes you through the science of steel making and casting, and looks at the processing involved.

Metallurgy Guru - Sustainability Materials Science - Making Green Steel with Hydrogen, 13022022

In terms of 'direct sustainability', the steel-making process can be significantly improved to reduce energy consumption and CO2 emissions by using ''green power' and Hydrogen. This lecture considers the use of hydrogen (in lieu of coal or natural gas) when manufacturing steel in blast or electric arc furnaces and the corresponding redox reaction that provides water as a reactant instead of CO2. Key mechanisms of hydrogen-based direct reduction & hydrogen-based plasma reduction are explained
