In the search for more efficient and sustainable energy generation methods, a class of materials called metal halide perovskites have shown great promise. In the few years since their discovery, novel solar cells based on these materials have already achieved efficiencies comparable to commercial silicon solar cells.

SKF and voestalpine Wire Technology, a subsidiary of the leading steel and technology group voestalpine, have successfully produced the first prototype bearing made from steel that contains hydrogen direct reduced iron (H-DRI). This represents a breakthrough in the efforts to decarbonize bearing production as H-DRI is a low emission alternative to conventional iron ore-based steelmaking and one of the important methods to make steel sustainable in the future.
