HYDROGEN JET FLAMES AND HYDROGEN EXPLOSIONS

As an energy carrier, hydrogen plays a crucial role in decarbonization and the future of a low-carbon society, where hydrogen production is one of the most important steps in the hydrogen chain. Hydrogen itself can be produced from different processes, and different colors were used to identify the environmental impact, where green hydrogen has been identified as the best in the future. However, the green hydrogen covers only about 1% of the world's production, even with increasing interest. Therefore, learning more about the green hydrogen production will be essential to reach the goal. In the course of hydrogen production, different technologies will be briefly discussed, and the green hydrogen production via water electrolysis or biomass gasification will be the focus, where the principle, component, process, together with sector coupling, will be discussed, and the state-of-the-art and the potential will be covered. To combine with specific implementation and special interests, one seminar, together with a report, will be arranged. It is expected that after this course, basic knowledge of hydrogen production technologies as well as their state-of-the-art and challenges will be clarified; Specific knowledge on the green hydrogen product from principle to the process will be provided, and the students can propose their ideas on how to promote green hydrogen production.

Vatten är den i särklass vanligaste miljön på jorden och vad som sker i haven påverkar allt liv på jorden. Även om människan inte bor i eller på vatten så nyttjar vi många ekosystemtjänster från vatten som matproduktion, transporter, elförsörjning och rekreation, och därmed påverkar eller förstör ekosystemen. För att kunna fortsätt nyttja resurser från hav och vatten eller utveckla nya värdekedjor krävs en omställning mot resursutnyttjande utan att riskera viktiga ekosystemtjänster.
