Grolleman, Sven (author)At the moment, Tata Steel emits 12.6 Mt CO2 per year while producing 7.2 Mt steel per year. To reduce these emissions, Tata Steel has decided to replace the blast furnaces with direct reduced iron (DRI) plants in combination with reducing electrical furnaces. The DRI plants will first operate with a 100% natural gas feed. Whenever green hydrogen...master thesis 2022

Bai, Y. (author), Wu, Jiansong (author), Yuan, S. (author), Reniers, G.L.L.M.E. (author), Yang, M. (author), Cai, Jitao (author)As a kind of critical infrastructure of energy transportation, so-called ‘utility tunnels’ have been developed around the world. Hosting a natural gas pipeline inside the natural gas compartment of a utility tunnel facilitates its maintenance but also brings potential explosion concerns due to the confined space. Although some work focuses on...journal article 2022

Burgers, Iris (author), Dehdari, Leila (author), Xiao, Penny (author), Li, Kevin Gang (author), Goetheer, Earl (author), Webley, Paul (author)Logistics of hydrogen is one of the bottlenecks of a hydrogen economy. In this study, a pressure swing adsorption (PSA) system is proposed for the separation of hydrogen from natural gas, co-transported in the natural gas grid. The economic feasibility of hydrogen supplied by a PSA system at a refuelling station is assessed and compared with...journal article 2022
