Energy Storage Batteries
There are many technologies for energy storage batteries , including the two most popular forms – lead-acid and lithiumion – and a variety of other battery chemistries , including nickel-metalhydride and sodium-sulphur .
Increasing global demand for minerals : new opportunities for mining companies and mineral rich-countries
The average amount of minerals needed for a new unit of power generation capacity has increased by 50 percent as the share of renewables has risen . As renewable energy technology demand continues to increase , so will demand for the necessary minerals .
Under a 2-degree scenario ( 2DS ) the production of graphite , lithium and cobalt will need to increase from 2018 levels by over 450 percent by 2050 to meet demand from energy storage technologies . Experts predict this global 2DC low-carbon switch will require $ 1.7 trillion of additional investment by mining companies over the next 15 years . The projections do not include the associated infrastructure needed to deploy renewable energy technologies , such as transmission lines and gas pipelines or that needed to support green societies , such as fully electrified public transport . As growth in demand for minerals soars , supply chains will need to keep up . m-mtoday . com 25
