2024-06-03 LDES Increasingly Competitive But Unlikely To Match Li-ion’s Cost Reductions

The cost of Lithium-ion batteries is still dropping and sodium-ion batteries use even lower cost materials, so it’s likely that the long duration energy storage – LDES – will not catch up for some time.  One LDES is green hydrogen, and hydrogen LDES systems seem to have stagnated, partly due to the falling prices of

2024-05-28 Many More EV Batteries – Solution To Grid Storage

Article about recycling EV batteries versus using EV batteries for stationary storage.  At this time, recycling is not very efficient. Quote: ““Today we are not very good at recovering metals, loosing almost all the lithium, silicon, phosphorus, aluminum, and graphite, while recovering only copper, cobalt, and nickel which are more expensive,” he says.”” This suggests

2024-05-12 Giant Batteries Are Transforming the Way the U.S. Uses Electricity

This link to the article is supposed to be free, and *not* behind a paywall.  This well-researched article is a good article, with some statements that are disputable.  One example is that they state that lithium batteries are flammable.  The LFP cells now used in battery storage systems are low to not flammable.  There are

2024-05-11 New Capacitor With 19 Times Power Density Could Help EV Batteries Last Longer

It looks like this supercapacitor could quickly charge and discharge, thus reducing the cycles on the EV battery.

2024-05-07 Lithium-free Sodium Batteries Enter Production

Natron enters low volume production.  The article says 70 Wh/kg, less than half of lithium.  “”…advantages such as faster cycling, longer lifespan and safer, non-flammable end use have made sodium-ion an attractive alternative…””

2024-04-30 IEA “Batteries And Secure Energy Transitions” Report

Quote: “”The IEA’s “Batteries and Secure Energy Transitions” report finds that capital costs for battery storage systems are projected to fall by up to 40 percent by 2030. This significant cost reduction will make combining solar and wind with battery storage more affordable than building new coal or gas power plants in many parts of

2024-04-07 Esbjerg Changes To Heat Pump City Heating System

The city of Esbjerg, Denmark is replacing its coal fired city heating system with an amazing giant heat pump, biomass boilers and waste burning boilers.  The refrigerant is CO2.  Read the description. This is a long 43 minutes but is very comprehensive and interesting.  The cost is about 40 million Euros. 

2024-03-21 EVs Enable The Global Decarbonization With V2G – Another Myth Debunked

Another myth debunked. This Electric Viking YouTube video under 10 minutes. “Quote from video starting at about the 8:06.  “Now, here is what Climate Energy Finance said about this study.  Batteries on wheels – electric vehicles – should be viewed as one of the most important enablers of the full decarbonization of the global energy

2024-03-20 Claims By House Committee Are Dubious

This is claiming that the grid will be overloaded, but that claim is contradicted by the latest figures that show the grid has use 1% **less** electricity. The following URL claims that the grid will not be able to handle the growing load.  This would be true *if* the grid was the only source of

2024-03-20 EV Myth Debunked, Buried

There is the constant criticism fueled(!) by the Big Oil and fossil fuels industries that EVs – electric vehicles – are going to overload the grid.  But this myth has been proven false by the latest statistics.  The amount of electricity on the grid went down 1% according to the figures from the EIA. Furthermore,
