Hydrogen - Decarbonizing the building sector - Why we can't afford not to have it

Over 90% of the approximately 21 million heating systems in Germany today are still powered by natural gas or oil. Building heat is therefore a major contributor to our energy consumption and CO2 emissions. However, if we were to rely exclusively on electricity to power heat pumps or electric infrared heaters in the future, the grids could quickly reach their limits. So what possibilities could green hydrogen play here? How far have we come technically with hydrogen heating and what is the political framework in Germany and the EU for decarbonizing the building sector with hydrogen? We talk about this with Leonie Assheuer, EU Affairs Manager at Viessmann.


  • 1.40: How mature is hydrogen technology today in order to use it sensibly in buildings?
  • 3.33: What requirements must be met in order to operate a hydrogen heating system?
  • 7.08: What are the advantages of switching to hydrogen for consumers?
  • 14.00: What role should hydrogen play in the decarbonization of the building sector in the EU?
