Conventionally, hydrogen has many fields of application in industrial processes, including as a protective gas in the manufacture of flat glass, in metallurgical processes such as bell annealing furnaces or as a high-purity carrier gas in semiconductor production. What they all have in common is that the hydrogen is not chemically converted, but primarily “only” contaminated. As a rule, however, this is then subsequently incinerated or, depending on the site conditions/infrastructure, at least partially used to generate energy (local heating network, CHP).
For small and medium-sized requirements, hydrogen generally has to be procured at high cost, whereby the price has risen significantly in recent years in line with natural gas, as hydrogen is primarily produced from natural gas using the steam reforming process.
On June 13, 2024, the Energy Saxony working group “Hydrogen in Industry and Commerce” in cooperation with Silicon Saxony e.V . invites you to a professional exchange on the topic of “Hydrogen recycling and reduction of supply quantities” and highlights the following aspects:
- Under what conditions does it make sense to treat and thus reuse the contaminated hydrogen?
- What technological solutions does the market offer or are currently being developed?
- What small- to medium-scale solutions are available to compensate for hydrogen losses or to substitute hydrogen?

The working group meeting is also intended to provide a platform for networking with representatives of the Dresden semiconductor industry, where hydrogen is already being used / is to be used in the future both as an energy source and as a raw material for industrial processes.
