When it comes to the 21th century the most important market is the one in the core of the energy transition. While green technology and sustainability market was valued at $10.32 billion in 2020, this is projected to reach almost $75 billion by 2030. Solar panels, wind turbines, electric vehicle (EV) batteries and other clean energy devices have one thing in common: critical materials. As noted by a report from the International Renewable Energy Agency (IRENA) the most important critical materials for the energy transition are copper, rare earth elements (REEs), lithium, cobalt, nickel and graphite. Their demand for the future is set to grow exponentially.
