Climeworks currently operates the largest plant in Iceland to scrub CO2 directly out of the atmosphere. Dirk Nuber is responsible for the company’s project development. He is looking for locations for further plants and preparing everything so that they can go into operation. Important points include large amounts of renewable energy for the capture process, […]


Interview with Fritz Vahrenholt

7. April 2023

The German energy transition as currently planned will fail. That is the opinion of Fritz Vahrenholt, former senator for the environment in Hamburg. 80 per cent electricity from renewable energies, as planned by the German government for 2030, cannot be achieved.

Interview Hansjörg Lerchenmüller

3. February 2023

Biochar is produced through pyrolysis – a low-oxygen process of biomass conversion. Residual materials are used in this process, for example waste from the timber industry or straw. Biochar is used as a soil conditioner in agriculture. This way, carbon is permanently stored in the soil. Pyrolysis is an exothermic process. Once started, it produces […]


Interview with Jens Wagner

30. December 2022

Green hydrogen or blue hydrogen, the terminology is of little importance to Jens Wagner of GasConTec. What matters to him is how much CO2 is released in the production of one tonne of hydrogen (or ammonia or methanol). In this sense, fossil-based hydrogen can even be better than hydrogen from renewables, thanks to carbon capture. […]


When will the German hydrogen economy arrive? Interview with Thomas Frewer from BP

2. December 2022

In 2030, 1500 kilometres of pipelines for hydrogen transport in Germany should be ready. From the north, where most of the gas is produced, it will reach consumers in the west and south of the country. The customers will be steelworks and the chemical industry, for example. But there is still a long way to […]
