there’s nothing worse than a flat battery. alright, maybe there’s a few worse things - but they do suck nonetheless.
to paint the picture:
you’ve just received a message that reads “netflix and chill?”. before you can respond_____________your phone dies. damn.
you’re on your afternoon jog, vibing to your “toned, tanned and terrific playlist” and then all of a sudden______________ dead. there goes that summer bod.
you’re on the phone to your significant other, hearing about their day, what they had for lunch and _______________. ok, we don’t mind that one.
but even more seriously, batteries are the key to our sustainable energy future. we’ve got no problem generating enough power to transition the world to a future where our cars, homes and phones are powered by the sun, wind and water, but storing all that power is a little trickier.
since the sun doesn’t shine all the time, and the wind doesn’t blow 24/7, we need to be able to store excess energy so that we can keep the lights on when mother nature can’t produce it.
but as we know, our batteries today kinda suck.
maybe that’s a bit harsh, but better batteries will be critical to our success in overcoming our fossil fuel addiction.
enter, hemp-based graphene.
you may have heard of graphene, which is this new high-tech material (one atom thick carbon) that may be the answer to all of our energy storage prayers.
it displays storage capacity well beyond that of traditional lithium-ion batteries, and its use in supercapacitors (charging devices) has been proven to drastically reduce charging times.
imagine charging your phone for 5 minutes for a week's worth of battery. graphene might make this possible.
the catch: it’s super expensive and extremely difficult to manufacture.
where it gets juicy is the research that shows that hemp fibre can be used to manufacture graphene for a fraction of the cost of traditional methods.
this is all thanks to hemp’s extremely high carbon content.
it’s still super early days, and way too soon to say whether it will see commercialisation, but the research is very promising.
a world powered by renewables and stored with hemp - now that’s a version of the future we can get excited about.
