A new report authored by Stephen Byrd, a utility and cleantech analyst at Morgan Stanley, and Adam Jonas, its auto analyst, shows that they are bullish on the market for grid storage products. “Demand for energy storage from the utility sector will grow more than the market anticipates by 2019–2020,” the pair says.
They predict the demand for grid-scale storage will increase from less than $300 million a year today to as much as $4 billion in the next 2–3 years because of the low price of wind and solar energytogether with the falling price of grid storage products.

The Future of Energy Storage Beyond Lithium Ion
https://www.youtube.com/watch?v=JxGP9cYbwdk
We have spent so much time digging into grid energy storage solution, and well this, might be the most promising solution we’ve come across. The ESS Iron Flow Battery requires no lithium, nickel, or cobalt. The only ingredients are water, salt, and iron. Flow batteries aren’t perfect, and they aren’t made for every application, but when it comes to grid energy storage, there’s a LOT to love about the ESS Iron Flow Battery! Let’s dig into it, on this episode, of Two Bit da Vinci!

The Future Of Energy Storage Beyond Lithium Ion
https://www.youtube.com/watch?v=EoTVtB-cSps
Over the past decade, prices for solar panels and wind farms have reached all-time lows. However, the price for lithium ion batteries, the leading energy storage technology, has remained too high. So researchers are exploring other alternatives, including flow batteries, thermal batteries, and gravity-based systems.

Uusi virtausakku voi ratkaista aurinko- ja tuulisähkön suurimman ongelman
https://etn.fi/index.php/13-news/14482-uusi-virtausakku-voi-ratkaista-aurinko-ja-tuulisaehkoen-suurimman-ongelman
Aurinko- ja tuulivoimalat tuottavat sähköä ilman päästöjä, mutta niiltä puuttuu käytännöllinen varastointiratkaisu suuren mittakaavan säätövoimaksi. Georgia Techin yliopiston tutkijat ovat kehittäneet uudentyyppisen virtausakun, joka on lupaava ratkaisu ongelman korjaajaksi.
Virtausakussa elektrolyytit virtaavat sähkökemiallisten kennojen läpi. Nykyisissä ratkaisuissa virtausakut maksavat yli 200 dollaria kilowattituntia kohden ja ovat liian kalliita käytännön sovelluksiin. Georgia Techin professori Nian Liun johdolla on kehitetty kompaktimpi akku, joka pienentää kennon kokoa 75 % ja vähentää vastaavasti koko virtausakun kokoa ja hintaa.
Virtausakut ovat saaneet nimensä virtauskennosta, jossa elektroninvaihto tapahtuu. Niiden perinteinen rakenne eli tasokenno vaatii tilaa vieviä virtauksen jakajia ja tiivisteitä, mikä lisää kokoa ja kustannuksia, mutta samalla heikentää yleistä suorituskykyä. Itse kenno on myös kallis.

This shockingly simple battery could store energy forever
https://bigthink.com/starts-with-a-bang/battery-store-energy-forever/?utm_term=Autofeed&utm_medium=Social&utm_source=Facebook#Echobox=1674576501
Capacitors, acid batteries, and other methods of storing electric charges all lose energy over time. These gravity-fed batteries won’t.
KEY TAKEAWAYS
One of the most annoying problems in energy storage is that of the battery: no matter how we improve it, stored electric charges always dissipate/discharge over time. Despite many attempted advances, the ancient “acid battery” and the nearly-as-old concept of a capacitor both remain unsurpassed as far as storing large amounts of energy go. Yet one even older technology, that of gravity batteries, could store enough excess renewable energy to keep the planet in business during off-hours or even off-seasons.
Nuclear fusion reactions, at least as will be achieved through inertial confinement fusion, release all their power in one shot, with significant time lags between successive shots.
The idea of collecting solar power in space and beaming it back to Earth is another future tech that is very promising for meeting energy demands, but that necessarily has significant time lags between the times at which energy is delivered.
Wind power is highly variable, both daily and seasonally, as it’s driven by the speed at which wind flows past the turbines that are designed to harness it. Because doubling the wind speed quadruples the amount of energy a wind turbine can generate, energy storage is needed to harness wind power during peak production, and then to release it at later times.
Solar power suffers from a similar failing as wind, with cloud cover, seasonal sunlight, and day/night variations creating severe differences in how much energy a solar power plant can produce, both over a day and throughout the year.
Many other sources of non-constant energy, including geothermal, (seasonal) hydroelectric, and even ocean-current power will also require similar storage capabilities to provide even levels of power, as required, throughout the varying days, months, and years.
If you want to store large amounts of electrical energy for on-demand use later on down the road, the leading technology for that comes in two forms: banks of either batteries or capacitors. Both of these storage devices are based on the same principle: the separation of different types of electric charges.
If only there were some way to put this generated electrical energy into storage in a way that would not dissipate, but that can then be released on-demand during off-peak times. The idea is that:
nuclear fusion plants produce too much energy to be used all at once, but rather each liberated burst could have its energy stored up and used over time until the next needed burst re-energizes the storage plant,
collected power from other means can be stored indefinitely until used as necessary,
and that wind, solar, and other renewables could have their excess energy accumulated and stored during windy/sunny times, and then released and utilized during still/cloudy/night times.
Perhaps the first type of potential energy we learn about is also the simplest and most straightforward: gravitational potential energy. Whenever anything with a mass drops from a higher elevation to a lower elevation in Earth’s gravitational field, including:
a ball rolling down a hill,
a book falling off a shelf,
a human falling from a standing to a prone position,
or a skydiver jumping out of an airplane,
you’re witnessing an example of gravitational potential energy being converted into energy-of-motion, otherwise known as kinetic energy.

https://www.uusiteknologia.fi/2023/03/08/suomalaisratkaisulla-vetya-tai-sahkoa-kumpaankin-suuntaan/
Suomalainen kiinteäoksidielektrolyysin SOE-polttokennoratkaisun kehittänyt Convion aloittaa öljy-yhtiö Shellin kanssa teknologiayhteistyön vedyntuotannossa. Yritys toimittaa Shellin Amstersamin yksikköön teollisen tason höyryelektrolyysin demolaitteiston, joka voi tuottaa vetyä tai sähköä kumpaankin suuntaan.
Shellin ja Convionin yhteistyön tavoite on tuottaa uusiutuvaa vetyä kiinteäoksidielektrolyysillä (SOE, solid oxide electrolysis), jonka hyötysuhde on huomattavasti korkeampi kuin muilla elektrolyysiteknologioilla. Yhteistyössä aiotaan validoida ja kaupallistaa Convionin kiinteäoksidielektrolyyseriiin perustuva (Solid Oxide Electrolyser, SOEC) polttokennotekniikka.
Suomalaisyrityksen elektrolyyseri voi toimia kahteen suuntaan eli tuottaa vetyä tai sähköä. Tässä hyödynnetään Convionin höyryelektrolyysereiden lisäominaisuutta, joka tukee elektrolyyserin kaksisuuntaista operointia (rSOC, reversible solid oxide cell).

How a Sand Battery Could Revolutionize Home Energy Storage
https://www.youtube.com/watch?v=KVqHYNE2QwE
Sand. It’s coarse, it’s rough, and it can make for a great sand battery. And as weird as that might sound, it’s just one example of the many earthy materials currently used for thermal energy storage (or TES). A while back, we covered the debut of the world’s first commercial sand battery, which is big enough to supply power for about 10,000 people. Now, sand-based energy storage has reached a new frontier: individual homes. Companies like Batsand are currently offering heat batteries that bring hot and fresh sand directly to your door. Seems you can get just about anything delivered these days.
