Exploring everything within energy storage like lithium ion battery technology, pumped hydro, hydrogen and more.
Hydrogen and fuel cells are often held up as one of the big solutions to getting off fossil fuels, but what if I told you that 95% of hydrogen is currently produced from fossil fuels? 1 This is when green hydrogen typically comes up. But what is it and how
Thanks to the rise of intermittent renewable energy sources, we’ve seen increased demand for new energy storage technologies, like batteries, pumped storage hydropower, and flywheels. But what if I told you that this little toy, a 200-year-old invention, combined with thermal energy storage might be
What you need to know before getting a Tesla Powerwall (first impressions and early review). There’s a few things I learned going through the installation process that might be useful if you’re thinking about getting a home battery installed. So let’s go through what you should know before getting a
When it comes to energy storage, our first thought usually is lithium ion batteries. But what if we went old school ... like just spinning things really fast and capturing that kinetic energy, old school. I thought I’d explain an example of a mechanical battery: the flywheel. And are they making a c
The lithium ion battery is great. They power much of the world around us and in our pockets, but trying to scale the technology up for renewable energy grid battery storage is challenging. What if there was another way? A method that used air to store energy? This ... could change everything.
Tesla opened a fire hose of engineering, manufacturing, and battery advancements in their Battery Day event. Not to mention the new Plaid Model S and a future $25,000 electric vehicle. But I think we can break the jam-packed event down into three big takeaways. And it's really not about batteries.
Exploring Tesla Powerwall and home batteries - worth it? I just got a Tesla Powerwall ... well, more like I've got a Tesla Powerwall ready to be installed. But with home batteries like this being so expensive, why would anyone want one? It goes beyond a simple "return on investment" discussion. In f
Supercapacitors explained - the future of energy storage? With Tesla’s battery day event not too far off, and their acquisition of Maxwell Technologies last year, I thought it was worth taking a closer look at what a supercapacitor is. Some believe that supercapacitors might be integrated into futur
Let’s talk about some hints that Tesla dropped in the last quarterly call around cell production, scaling manufacturing, and EV range expectations. And how Tesla is pulling something from Apple’s playbook.
If we want to replace fossil fuels entirely, we need to build batteries that can store enough renewable energy to power entire cities for much longer periods. With liquid redox flow batteries, there's a viable path forward for city-scale renewable energy storage. But where do we currently stand with
There’s been a lot of hype around solid state batteries for years now, but where do things stand today? And how much longer do we have to wait before seeing solid state batteries take hold in the technology we use every day? Let's take a look at the latest research, lithium ion batteries, and John B
Thinking of getting solar panels or already have them? You might be looking at a solar battery like a Tesla Powerwall, Sonnen Eco, or LG Chem RESU. How do they work? Why would you want one? How much do they cost? While there’s some good options available, there’s a lot to chew with this one. Let’s s
