The BIGGEST problem with clean energy
yt.artemislena.eu
To reach our global goal of being net zero carbon emissions by 2050, we must solve one problem - energy storage. Thank you to Toyota for lending us the #Mirai and for sponsoring this series. Scientists, researchers, and engineers are working to develop innovative ways of addressing the intermittency of wind and solar energy. I got to talk to them in part 3 of my renewable energy road trip with Toyota in their #Mirai Previous videos in this series: The Truth about Driving a Hydrogen Car [https://youtu.be/hghIckc7nrY] Hydrogen vs. Battery Electric Cars [https://youtu.be/dWAO3vUn7nw] Upcoming video in this series: Concentrated Solar Creator/Host: Dianna Cowern Editor: Levi Butner Producer: Hope Butner Production Assistant: Laura Chernikoff Story Consultant: Patrick Muhlberger Research: Sophia Chen and Erika Carlson Support Physics Girl https://www.patreon.com/physicsgirl http://physicsgirl.org/ http://twitter.com/thephysicsgirl http://facebook.com/thephysicsgirl http://instagram.com/thephysicsgirl Special thank you to our X-Ray tier patrons: Carlos Patricio, David Cichowski, Eddie Sabbah, Fabrice Eap, Gil Chesterton, Isabel Herstek, Margaux Lopez, Matt Kaminski, Michael Schneider, Patrick Olson, Vikram Bhat, Vincent Argiro, wc993219 Resources: https://unfccc.int/sites/default/files/resource/LTS1_RKorea.pdf https://highwaysengland.co.uk/netzerohighways/ https://iea.blob.core.windows.net/assets/beceb956-0dcf-4d73-89fe-1310e3046d68/NetZeroby2050-ARoadmapfortheGlobalEnergySector_CORR.pdf https://www.iea.org/reports/net-zero-by-2050

    Yes in a scenario, which you are in a cold climate which it is always cold outside. Then yes, thermal energy storage would be an extremely efficient option.

    I’m not sure I follow why this is an edge case. Space heating indoor areas with surplus wind energy stored in september-november when it peaks is the absolute largest block of inflexible demand for >100 hour storage. With PCM or suitable risk management of high temp. sensible heat it represents the plurality of potential storage demand.

    Batteries may still win due to flexibility and prevalence of solar, but I can’t think of a better use case for thermal storage.

    It’s also probably the oldest storage tech by about 8000-100,000 years

      heating is not done year around (365.25 days/year) for the majority of the world’s population.

      Hence why places which need heating year around are generally considered an edge case.

        (i edited above accidentally hit enter too soon)

        Long duration storage isn’t used year round. Charge with wind in autumn->don’t burn stuff during jan/dec or dunkelflaute isn’t an edge case, it’s about 10% of all energy and the only real use case where renewables absolutely need LDES.
