Synthetic energy carriers like chemically produced methane can make green energy transportable and storable for long periods. The problem: The production is associated with relatively high energy losses. On top of that, the processes up to now also require additional purification of the methane...
More than four billion tonnes of cement are produced worldwide every year. In the process, the building material inevitably releases large quantities of the carbon dioxide bound in the lime. Cement manufacturers, such as CEMEX from Mexico, are meeting the gigantic challenge of decarbonizing the...
