How HEMP is Making GREEN Tech
Hemp has already established itself as a green alternative for building and textiles among other things, but most don’t realize that HEMP fibers pack a powerful punch. In fact, scientists have reported that fibers from HEMP can have as much energy and power as graphene and could take its place as the model material for supercapacitors.
What’s a supercapacitor?
Supercapacitors are energy storage devices that can charge and discharge within seconds, unlike standard rechargeable batteries that can take hours to charge. This will revolutionize how we power our appliances and devices. By powering our devices with renewable industrial hemp, we stand to have more power and less waste.
How can hemp be transformed into a supercapacitor?
Scientists are heating hemp bast to 350 degrees Fahrenheit for 24 hours and then blasting the resulting material with even more intense heat, creating carbon nanosheets. These sheets can be used used as electrodes and ionic liquid to build the capacitor.
How do they measure up?
Fantastically! Fully assembled, the hemp derived supercapacitors performed 2-3 times better than commercial supercapacitors made with Graphene and operate over an astonishing range of temperatures. In the not too distant future hemp batteries and capacitors will be widely available, making it a simple task to power our devices in more eco-friendly ways.
