When I Google large recent projects, I see 4hrs [1][2] or (at 1.3GWH!!) 2 hours[3] of storage at much more than 10MW, and at lower prices today than the people selling nuclear hope to reach in 10 years. Nuclear is good! We should deploy it as fast as we can! That happens to be quite slow relative compared to our deployment of utility scale solar and wind. Let's go faster if we can. But for heavens' sake, nuclear advocates should, well, advocate for nuclear, not badmouth the clean energy coming online today at grid scale.

That's at $80-120/MWh though, much higher than the GPs $35. Agreed though it is exciting to see the cost drops - but it's important to compare like for like wrt to intermittency.

  That's the price range for the Hawaii projects. The cost for the (much larger) Eland and Gemini projects is $35 MWh (previous and [4], respectively). WRT intermittency, the point of this conversation is that hydrogen generation is a solution: over-provision and generate combustible hydrogen (or ammonia, etc) that can be used later and / or where electricity performs poorly: long haul transport and high-temperature industrial processes.

    Isn't hydrogen one of the hardest things to transport?
