Considering the highly ambitious GHG reduction targets that both the German government and the European Union have announced for 2050, it seems hardly enough to transform only the electric power market. Each part of the economy must see dramatic changes if the goal is a zero-carbon future. This also includes the steel industry, which produces around 6 percent of the carbon dioxide emissions in Germany

In the 1960s and 1970s, the UK put in enormous efforts to replace the ubiquitous town gas with natural gas supplies. The former, manufactured locally, contained more than 50 percent hydrogen. The proportion dropped to zero once the network was converted and about 40 million appliances were adapted for natural gas, delivered from the country’s North Sea fields. But today, something old could be new again, as one city is planning to switch its pipeline system to pure hydrogen and serve as a model for the rest of the country.

Over the past years, Erlangen, in the German state of Bavaria, has become known as the world’s epicenter of LOHC research. It was here that Wolfgang Arlt, a professor at the Friedrich-Alexander University of Erlangen-Nürnberg, conducted his initial experiments on carbazole and other LOHCs, short for liquid organic hydrogen carriers, in 2011. The city is also home to companies such as Hydrogenious and Framatome
