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 …
New, Completely Unworkable Concept in Energy Storage Read More »
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 …
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 …
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 …
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 …
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 …
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 …
Energy storage consulting group CleanHorizons offers this week’s top five projects in this space:
More than 90% of the energy storage in the United States today is pumped hydro, using surplus energy to pump water uphill, and harvesting that energy by releasing the water to flow downhill through a turbine. There are several variations …
Here’s an article that claims: South Korea wants to build three hydrogen-powered cities by 2022. Though this might sound legitimate on the surface, we need to realize that hydrogen is a carrier, not a source, of electricity. This, therefore, is …
