Sean White‘s Solar and Energy Storage Podcast

World’s Largest Battery Energy Storage Systems (BESS)

There are many ways to define the largest BESS and since the industry is growing so excitingly fast, it is difficult to explain exactly which is the largest.

 

We are going to talk about 7 big ones here:

 

1. Vistra: Moss Landing California US 2021 400MW/1600MWh

2. Crimson Storage: Blythe California US 2022 350MW/1400MWh

3. Manatee: Florida US 2021 (largest with PV) 409MW/900MWh

4. Victorian Big Battery: NSW Australia 2021 300MW/450MWh

5. McCoy Solar / BESS: Blythe California US 2021 230MW/920MWh

6. Elkhorn Battery: Moss Landing California US 2022 182.5MW/730MWh

 

Number 7 on this list is not the 7th largest battery today, but gets mentioned because it was once the largest in the world, first to reach 100MW way back in 2017 and was made because of a crazy social media bet.

 

If you are listening to this podcast in 10 years, it will be funny to compare these largest systems to the new largest BESSs in the world. What will they be? 100GWhs? Crazy to imagine this kind of growth!!

Lithium-Ion Battery Chemistries

Sean is recording this podcast from Australia where he is about to teach a utility-scale battery energy storage systems (BESS) course for CPD International. This is some of the material that will be included in the course.

 

In this podcast, we will go over different battery chemistries, focusing on the three main types of lithium-ion batteries used these days, which include:

 

1. Lithium Iron Phosphate (aka LFP or LiFePo or LiFePo4)

2. Lithium Nickel Manganese Cobalt Oxide (aka NMC or NCM)

3. Lithium Nickel Cobalt Aluminum Oxide (aka NCA)

 

We will talk about the availability of these elements on Earth, the toxicity of them, we will compare and contrast to lead-acid and nickel iron batteries and we will take a dive into the controversial Cobalt, which is said to have a supply chain where child labor is often used in the Congo. Australia does lithium and cobalt mining, which is part of the solution, however the use of cobalt free lithium-ion batteries, which means LFP seems to be the solution, however the batteries with cobalt do have a higher specific energy (not to be confused with energy density).

 

Specific energy = energy per weight (most important for EVs)

Energy density = energy per volume

Microgrids

"Microgrid" is a term that is thrown around a lot and a lot of people using this term are not using it as it is defined in the NEC. The 2023 NEC has a few new microgrid terms. Additionally the 2023 NEC has renamed AC Coupling and DC Coupling  to be AC Interconnected and DC Interconnected.

Herve Billiet, Co-founder and CEO, Ipsun Solar and Ipsun Sunvoy

Herve Billiet is an electro-mechanical engineer who co-designed the first Belgian solar car way back when he was 21 years old. Soon after, he was invited by MIT in Boston to advance its sustainable transportation initiatives.

 

He went on to design his first residential solar PV system in 2009 using the 2008 National Electrical Code. Herve is from Europe but he knows the National Electrical Code he's not an expert over there designing solar systems in Europe.

 

And another thing is he worked for a few consulting firms, Accenture among them, and the US Department of Energy as a Strategy Consultant working on some of the largest renewable energy projects in the world. I bet that's getting bigger every day.

 

He's a business partner with Joe Marhamati whom he met at the Department of Energy’s Headquarters to establish Ipsun Solar. Herve and Joe grew Ipsun Solar from a small local installer to a prominent installer in the Northern Virginia Washington DC area doing both residential and commercial solar and advocacy for solar. Herve and Joe were seen roaming the NABCEP conference. Cool dudes! While they were running a solar business Herve saw the need for better software and co-founded Ipsun Sunvoy and we're going to get into what they do but they make tools and things coordinating different types of software and communications together. It’s awesome!

 

He’s a proud father of three boys, a CEO and he is fighting climate change.

Climate Change Activism Coupling (CCA-coupling)

At the COP 27 conference there was a lot of talk about other issues besides climate change, which I thought was interesting. Here were my notes:

 

I find it interesting at COP27 that there are a lot of other issues that are not directly about solving the CO2 crisis. Human rights, sexual rights, indigenous rights and economic injustice are all very important and all can be indirectly linked to climate change problems, but we need to get the jerks that are against justice on the side of reducing CO2 growth fast in order to move forward fast.

 

There are many jerks, especially in Florida (that’s a joke), that see human rights as something called “woke” and then when you combine it with CO2 problems, they are automatically against both at once. We need to fix the emergency, make the race to lower the CO2 rate an economic issue that even greedy selfish people can stand behind. Greedy selfish people can stand behind energy security, energy independence, ramping up the cheapest form of energy production, factories in America, good paying jobs, making it a made locally issue. We are not going to get there without the greedy selfish people on our side. We must get along!  We are at a time when doing the right thing is also doing the greedy thing, since renewable energy is the future and will make the next wave of millionaires and billionaires.

 

This podcast was originally written at the UN COP27 conference in Egypt in November 2022 and then tied up back at home.

Egypt COP27

This podcast was recorded at the COP27 climate conference in Sharm El Sheikh Egypt on November 16 2022. 

 

COP stands for something boring, Conference of the Parties, which means that countries and other organizations are the parties. Sometimes I look at what our countries are doing and it is like we are having a big fossil fuel party! It is literally powering parties like Burning Man with flames of fuel! Anyway, this is the 27th year of COP, so it is called COP 27 and the more famous one was in Paris, when they made the Paris Accord or Paris Agreement, back when we had a very famous and likable Kenyan President at COP 21. This is where the US, China and all of the other big CO2 emitters made an agreement to do things to limit temperature rises to 1.5C over preindustrial levels. Being an American, I do not like the 1.5C number, since we use F for Fahrenheit and a change of 1C is the same as a change of 1.8F, so 1.5C x 1.8 = 2.7F. Anyone that uses F for the temperature of their house or the beach should not use C only when they are talking about climate temperatures, unless they are trying to downplay the emergency. Not since the rock that took out the dinosaurs (except for the birds, which are dinosaurs) has the climate changed so fast. Humans are extremely smart and can tell the temperature of the earth throughout the ages and the CO2 in the atmosphere. There have always been slow gradual changes, but nothing like this without an asteroid. We humans are so smart, that we can also fix this emergency very fast.

 

The big topic in the news this year is about having the rich countries that have contributed the most to CO2 in the atmosphere to help pay for the other countries that are too poor to do much about it. They have high interest rates, to the point where it is like financing things on a high interest credit card, which is financially impossible to make and investment world form.

 

The problem I see is that in the biggest polluting country of them all, my country, the USA, we have something called politics and there are enough people against paying for our original sin (we are in a biblical place here), that it is not going to happen on a big scale, no matter how bad the US President wants it.

 

So what is going to make this happen?

 

Here is my solution…

I see that humans and other organisms can grow like a virus (go viral). You see doubling rates and as many of you may know, of you double a dollar for a month, you have over a billion dollars. In fact if the month has 31 days, you get 2x more than a 30 day month.

 

Now we can translate this to a disruptive technology, such as solar, wind and storage. We are getting doubling rates and the trick here is to speed up the doubling rate. Not to accept a 4 year doubling rate, to go for a 1 year doubling rate. Some pessimists will have plenty of reasons why this cannot happen, and the answer is that the reason that this cannot happen is if we listen to pessimists.

 

We have to scale like we are putting the effort of a world war into it and the big thing here is instead of having a war and having a lot of people die, we have seen that wars can be good for the economy, so we can have a huge economic boom, without the war deaths.

 

It is inevitable that we will scale up solar, wind and storage, the question is how slow (or fast) are we going to go? If we go fast, there are many benefits, plus we are going to do it anyway, so let’s get it done.

 

Solar and Wind are already the cheapest forms of energy in the world. Energy storage is getting less expensive and in a few years, it will economically stupid to buy a new car that is not an EV and these EVs can easily be plugged in and wired for grid support, which will happen. The question is, are we going to sit around and whine, or are we humans going go get it done!

 

We are humans. We are the smartest thing in the universe. We can easily figure this out. If we put in an effort, we can pick a temperature and dial it in. We can put CO2 from the atmosphere back underground where it came from and set a thermostat. We are humans. We can do anything we set our minds too. It will happen, the question is when. Waiting is stupid. Getting it done now is smart and makes big money.

 

If the poor countries want a strategy, they can align themselves with the counties that help them set up solar, wind and storage. If the US wants to set up a base on some island, then it needs to come with solar, wind and storage. Perhaps if the island nation has a low credit rating, the US (or other country) can bring their credit rating to the base.

 

There are other low CO2 solutions, but we see right now that solar and wind are the least expensive, so it is a scaling solution. We need factories, good labor, robots making robots that make PV, wind and solar. 

 

If we distract ourselves with excuses, neat ideas that do not come to fruition and blame for what someone did 50 years ago, then we will keep walking in circles. The solution is here. The solution will bring us out of any recession. The solution will create jobs, the solution will help children breathe clean air. The solution is scaling up big time solar, wind and storage. No excuses. All positive. Let’s get going.
