Back in my engineering days, I presented a paper on ๐๐ช๐๐๐ข๐ก, a bladeless wind-based power generation system.
After the presentation, my professor pulled me aside and said:
โ๐๐ฅ๐ฏ๐ข๐ฏ, ๐บ๐ฐ๐ถ ๐ด๐ฆ๐ฆ๐ฎ ๐ฎ๐ฐ๐ณ๐ฆ ๐ฆ๐ฏ๐ต๐ฉ๐ถ๐ด๐ช๐ข๐ด๐ต๐ช๐ค ๐ฑ๐ณ๐ฆ๐ด๐ฆ๐ฏ๐ต๐ช๐ฏ๐จ ๐ต๐ฉ๐ฆ ๐ฅ๐ช๐ด๐ข๐ฅ๐ท๐ข๐ฏ๐ต๐ข๐จ๐ฆ๐ด ๐ฐ๐ง ๐ต๐ฉ๐ช๐ด ๐ด๐บ๐ด๐ต๐ฆ๐ฎ ๐ต๐ฉ๐ข๐ฏ ๐ต๐ฉ๐ฆ ๐ข๐ฅ๐ท๐ข๐ฏ๐ต๐ข๐จ๐ฆ๐ด.โ
He wasnโt wrong.
I told him straight, Iโm all in for renewables, but I genuinely didnโt believe any of them could scale to grid-level integration. Sure, theyโre great for green credits, marketing, and small systems. But can you actually dispatch them on demand? Wind blows when it wants. The sun sets when it wants. Even if we crack efficiency, availability is a whole different problem.
He just smiled and said, โ๐๐๐๐๐ฃ๐ค๐ก๐ค๐๐ฎ ๐ช๐ฅ๐๐๐ฉ๐๐จ ๐ซ๐๐ง๐ฎ ๐ฆ๐ช๐๐๐ ๐ก๐ฎ.โ Then laughed.
More than a decade later, heโs having the last laugh.
I watched solar and wind generation overtake conventional power sources by massive margins across multiple countries. Efficiency clearly improved. But my old question kept coming back: what about availability?
Thatโs when I discovered ๐ฝ๐๐๐ โ ๐ฝ๐๐ฉ๐ฉ๐๐ง๐ฎ ๐๐ฃ๐๐ง๐๐ฎ ๐๐ฉ๐ค๐ง๐๐๐ ๐๐ฎ๐จ๐ฉ๐๐ข.
It was the missing piece. The technology that finally answered my decade-old skepticism and helped renewables go mainstream.
My curiosity led me to Sergey S.โs course on Udemy, an incredibly thorough overview of BESS, covering everything from individual cell chemistry all the way to project finance and bankability.
If youโre in the energy space and havenโt explored BESS yet, itโs worth your time.
