Aluminum , one of the most abundant minerals in the Earth ’ s crust , could be the key to unlocking low-cost green hydrogen .
Fueling the future : unlocking low-cost green hydrogen
Hydrogen is well positioned to be the fuel of the future . However , a commercially viable transition to green hydrogen – the environmentally friendly version of the fuel – seems perpetually 10 – 15 years away . While current production techniques like electrolysis continue to improve , they still are not able to unlock the potential of green hydrogen for one simple reason : cost .

Hydrogen , the most abundant element in the universe , is an incredibly efficient form of energy that produces zero emissions when burned . Yet , corporations , investors , and even many governments are hesitant to heavily fund technologies that are not cost-competitive with existing alternatives . Fortunately , two notable advancements in green hydrogen production are promising to close the cost gap .
These innovations differ from the two most common forms of generating hydrogen today by employing one of the most abundant minerals in the Earth ’ s crust to unlock low-cost green hydrogen . The developments , which utilize aluminum and water to produce hydrogen , could enable large-scale operations like power generation plants , along with numerous other applications . As a more near-term solution , cheap ,
