The German lime industry emits 6 million tonnes of CO2 per year . Two thirds of this cannot be avoided because they are produced when the lime is burnt. Another third comes from the fuels used in the processes. In order to bring the emissions of the lime industry (and those of the cement industry […]

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, […]

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. There will not always be wind and the sun only shines during the day. […]

The first carbon capture plant in a German cement plant is in operation, in the Bavarian town of Rohrdorf near Rosenheim. Using the captured CO2, a product for the chemical industry is created, namely formic acid. With the pilot plant, the operator wants to open up a way to use CO2 as a valuable material, […]

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 […]

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. […]

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 […]

Climate-friendly transport is a service that is increasingly in demand. The logistics company Kuehne+Nagel offers a range of instruments to achieve this goal. For example, the compensation of CO2 emissions from conventional fuels. Kai Miller of Kuehne+Nagel is convinced that there will not be one solution for climate-friendly transport by sea in the future. This […]

In 2002, Urs Weidmann founded the Silent-Power AG in Switzerland. He wants to help the methanol industry achieve a breakthrough, develop a CO2-neutral value chain and expand his company into an energy service provider. For Weidmann, methanol, not hydrogen, is the ideal synthetically produced energy carrier. He has been convinced of this for 40 years. The entrepreneur relies on the fundamental findings of George A. Olah, who was awarded the Nobel Prize for Chemistry in 1994. Now, the hour of practice has come for Weidmann.

According to Ineratec it is currently building the world’s largest production plant for synthetic fuels. The output of the pioneering plant at the Industriepark Höchst in Frankfurt is to be up to 3,500 tonnes per year. Ineratec is currently primarily targeting air traffic – a risk-free market. After all, the EU Parliament demands fixed blending […]
