New Energy Storage Systems From Thin (Compressed) Air Can Compete With Li-Ion Batteries
A new analysis indicates that compressed air energy storage systems can beat lithium-ion batteries on capex for long duration applications.
Compressed Air Energy Storage (CAES)
Compressed Air Storage Redux — LightSail & Hydrostor
The other day, I published my doorstop assessment of the thermodynamics and operational challenges that limit compressed gas storage solutions, pushing them into the 100 GW of also-ran capacities. In comments in various places, people reminded me of the long-defunct LightSail and the now-getting-press Hydrostor. A bit of followup with … [continued]
Long Duration Energy Storage From Thin Air: Just Add Water
New long duration, large scale compressed air energy storage system leverages simple water pressure to cut costs.
Texas Shatters Own Solar Power Record, Weird Political Situation Or Not
Texas continues to rack up the renewable energy wins with a record-breaking month for solar power capping a surge past coal.
Benefits of Hydropower for Grid-Scale Energy Storage Highlighted in New NREL Analysis
Assessment Shows Global Warming Potential Lowest Among Technologies Studied
Curtailment Is The Easy Answer
In a recent article, we found that curtailment of renewables may be cheaper than grid scale energy storage. Sometimes, the simplest solution is the best solution. However, given the complexity of electrical grids around the world, we should also look at all of the available solutions to make sure we … [continued]
New UK Energy Storage Idea Is As Dumb As A Box Of Rocks
Researchers in the UK claim injecting high pressure air into the porous sandstone beneath the North Sea could store enough energy to meet all the country’s energy needs during the winter. It might be the ideal way to store energy from offshore wind turbines.
12 Gigawatts Of Battery Storage In UK Is Possible By 2022
A new report published last week by the All-Party Parliamentary Group on Energy Storage concludes that installing 12 gigawatts of battery storage is achievable in the United Kingdom by the end of 2021, but that a “medium” target of 8 gigawatts is more likely.
Ruh-Roh: New Texas Wind Energy Storage System Should Make Coal Nervous (And Natural Gas, Too)
The nation’s first compressed air energy storage system in almost 40 years spells yet more trouble for coal industry stakeholders.
Getting The Last 20% Of Our Energy From Renewables
A number of people made some really interesting comments on my recent CleanTechnica article, “Mark Z. Jacobson & The 100% Renewable Energy Naysayers.” Some of these had to do with the problem of getting the last 20% of our energy from renewable sources, after we got to the 80% mark.
