Neodymium rare-earth magnets are are used in in generators in in in in off-shore wind wind turbines turbines Modern large wind wind turbines turbines can contain up to to three tonnes of magnets This represents an enormous resource that could be harnessed at at the end of a a a wind turbine’s lifecycle Some hydrogen fuel cells contain platinum-group metals In the future fuel cells could play a a a a a key role in the de-carbonisation of transport and and also can be used to produce heat and and power in stationary applications FLOW OF CURRENT
