Content Data

This page contains data entry 75568 from the Axioma AXP content repository. The structured data below represents the complete record for this entry.

This article kind of sucks but this is an actual technical challenge with renewables that we don't really have a great solution for. Solar in particular has a production curve that peaks at a totally different time than the demand curve does. That's a problem, because every major grid in the world uses alternating current and alternating current requires demand be matched closely to supply or else things get hairy really fast. We need ways to offset that supply and right now there aren't a lot of good answers. Chemical batteries are okay but producing them on the scale we need is difficult to do right now. There's a lot of exploration happening with alternative energy storage techniques like thermal batteries and pumped hydro, but nothing we can really work with at scale yet there either. So producers resort to lowering prices to incentivize buyers, even in some cases literally paying someone to take the power (negative pricing, as the article mentions.) But that only works as long as there's a buyer. As more renewables come online finding buyers for the excess production is going to get more and more difficult. We need workable grid scale energy storage ASAP or else renewable deploys are going to stall completely as producers increasingly find it just isn't technically viable to bring even more renewables online and make the existing problem worse.
