What a year it's shaping up to be for. Storage manufacturing has taken a hit and some projects are getting delayed for obvious reasons Our analysts that would mackenzie say that. The coronavirus crisis will trim twenty twenty forecasts for Battery Installations. Globally by almost twenty percent. But they still expect it to be a record year and the projects that caught our eye are not going to get built this year but they do show the strength and resiliency of this market a few examples here. A coal plant in North Dakota is going to be replaced. In part with a one acre battery array that uses a new technology capable of discharging for a hundred and fifty hours. That's more than thirty times longer than a lithium ion batteries. The Electric Utility in Hawaii just awarded contracts for sixteen projects that add up to more than three gigawatt hours of storage and those will replace an oil fired. Coal-fired Power Plant in California Southern California Edison signed contracts for seven hundred seventy megawatts of batteries. Many of them paired with solar projects to replace aging gas plants plus in China more hybrid wind solar and battery plants are starting to emerge and wood. Mackenzie expects rapid growth in batteries within China in the coming years. It's the country will lead Asia. This lead Dan Foley who would McKenzie's head of energy storage to proclaim to our journalist at Green Tech Media The utility energy storage market is blowing through milestones faster than we can report them for example those Sei projects are together worth two hundred megawatts more than the entire twenty nineteen market says Fin Foley. So let's go through these. I think we should focus on the bright shiny objects I. What do we know about this form? Energy Project Catherine mentioned this at the end of a recent show so catherine what is Great River Energy who is form energy and what kind of battery could emerge from. This relationship is a great river. Energy is the largest generation and transmission co-op and what that means is it generates and provides power under long-term contracts to a bunch of member. Co Ops like twenty eight member Co ops and this is how a lot of the COP system is formed in the US where they're small co ops that are often serving rural communities. They are very much about keeping costs low for their customers and customers. Own the CO OPS. They are customer owners but then they sign up for long term agreements with these GMT providers. Because it does save the money in the long run and a lot of these. Gmt providers we've seen have these long term contracts For old coal plants and so great river energy is one of those GM GMT's and they made a decision a while back to shut down coal a coal plant call strip and they have been thinking about. How are we going to backfill it? And what are we going to use to do that? And so they've certainly been deploying a lot of renewables and they just recently entered into this agreement with Form Energy and forum is a start up Led by Matteo Harm. Yo who came out of TUSLA. He was the energy storage guru there yet mingchang. Who's an MIT professor? Who has been really another brains behind storage and Ted Wiley who co-founded Aquaman and energy storage company and there are a couple of other. Mit folks. Billy Woodford and Marco Ferrara and there. It's just a team of incredible minds. Who decided to try to calm at storage by thinking about it it as potentially being able to replace all of these Uncaught non cost effective coal plants and so their technology seeks to be super cheap long-duration Nontoxic something you would find everywhere to be able to you know. Put together a type of a flow battery that could just replace the footprint of any fossil fuel plant so that is their goal. And that's what a great river energy has decided to take a bet on. Let's talk about the tech first and then the rural cooperatives piece second jigger. This is a battery. We don't know much about but they call it an aqueous air battery. What does that mean well? Basically in it uses more abundant materials. Because what you find is as that the metals wondering yeah we'll water but also the metals they're using or quite Easy to find and so it's aluminum zinc magnesium etc right. And so so what you find is that they have this ability to use low-cost materials right and they're able to Store lots of energy so when you think about this ad. Matteo talks about this in his interview The way that Lithium. Ion Batteries work is that you can actually charged quickly and discharged quickly but at the same time basically to charge it as to discharge it. And so what you find. Is that these batteries It's around like sort of being able to constrict the nozzle and only making it one megawatt right because you can imagine that you could make a lithium ion battery that's a hundred megawatts incised but only dispatch one megawatt at a time and then make it last one hundred fifty hours now. The problem with that those. It's a super expensive way to get one hundred fifty hour battery whereas this is a much cheaper way. It's it's similar to sort of Etienne redux batteries and others were the basically have this. The fluid that that holds the charge can be expanded at a very low cost. The fuel cell that converts that fluid into energy that's utilized is the expensive
