1, ‘Heat batteries’. A Finnish company will supply a 100 MWh heat battery to a municipality near Helsinki. This battery contains a type of sand that is heated up by electricity when supplies are abundant and the high temperatures can be retained for weeks or months if necessary. The heat is then transferred to the water in the town’s district heating system in winter. The transfer outwards can be up to 1 MW, not a huge flow but which helps reduce the costs of running the heating system. A conventional battery would be able to deliver a much faster energy transfer but the land area taken by the heat battery - about 230 sq metres – is far less than would be needed for lithium ion.
Re low-carbon cement, how does the Fortera process compare to Brimstone's product, which reportedly has the potential to be carbon-negative and less expensive than conventional cement?
