Here’s another one of those clean energy concepts that falls under the category: “will ‘work,’ but would be so ridiculously expensive that it will never be built.” It’s an idea in the energy storage space that’s a variant of “advanced …

Energy Storage Is Changing the Game
The integration of large percentages of renewable energy is notoriously limited because of variability, though there are several tacks engineers take to mitigate this. One, of course, is gas peaker plants. In some parts of the U.S., large solar and …
New, Completely Unworkable Concept in Energy Storage
Six or eight years ago, a client paid me a small fee to provide my opinion of a concept called “advanced rail energy storage,” or “ARES.” It’s essentially pumped hydro without the hydro. In other words, it replaces water with …

Feasibility of Hydrogen
Reader Markus Dirnbacher asks, Sustainable hydrogen – amongst all currently available technologies- will be the only possibility for long term storage of power! Do you agree? No, this is extremely unlikely to happen. Batteries are making great progress, and synthetic …
Sulfur Flow Batteries
2GreenEnergy supporter Gary Tulie writes from his home in England: Hi Craig, If these people succeed in their target of achieving long term energy storage at a cost of $10 per kWh using sulfur flow cell batteries, they could change the …

Getting To 100% Clean Energy
How can we achieve our quest for 100% clean energy? Let’s start with the understanding that nuclear, while it’s very clean, is baseload, i.e., it can’t be ramped up to address the quite significantly changing loads that we experience through …
Energy Storage
Here’s a piece on the five most viable energy storage technologies, and I’m happy to see that compressed air (CAES) is among them. By way of update, the CAES project I represent appears very close to getting the funding it …
Green Battery for the Developing World
Here’s a battery energy storage concept that is proposed for cell phone charging and high-efficiency lighting in the many parts of the developing world that, otherwise, have no access to electricity. The product will cost about $12, and the consumables …
Dubious Energy Storage Concept
Can energy be stored by pushing heavy stuff uphill? Of course. That’s what pumped hydro is, which represents over 95% of the utility-scale energy storage current implemented on this planet. It’s also what advanced rail energy storage (ARES) is, which …
