State-owned Swedish utility Vattenfall has revised its plan of achieving zero net carbon emissions by 2050, instead saying that it expects to meet the target earlier, perhaps by 2040 or 2045. A number of technical solutions still need to be developed to be able to achieve carbon neutrality, in the view of CEO Magnus Hall, including energy storage. If Vattenfall did manage to achieve its aim before 2050, it is likely to be the first major traditional utility to do so in the world.
