2021-06-01 Hydrogen Electrolyzer For Quebec

I’m hopeful that more of these green hydrogen electrolyzer systems are going to be installed. The hydrogen is accomplishing more than one thing. The electrolyzers are putting to good use the excess renewables power that would otherwise be wasted. The green hydrogen is, of course, being used to replace fossil fuels, and thus reducing CO2

2021-05-30 Rooftop Solar+Batteries Make A Clean Grid Vastly More Affordable

This article (or video) has some good graphs for future distributed PV plus batteries.https://www.volts.wtf/p/rooftop-solar-and-home-batteries A map of generation sources in the US. https://mobile.twitter.com/VibrantCE/status/1338560961280618502/photo/1

2021-05-25 Solar, Wind + Batteries Are The Cheapest

This YouTube video from Tony Seba of RethinkX shows the incredible cost reductions that have been and will be made to the cost of solar, wind plus battery storage. “SWB100” is his acronym for 100% solar, wind plus battery storage. Seba states that SWB100 will be so low, per kWh, that it costs less than

2021-05-21 Green Hydrogen And 100% Renewables Plus Storage

The halting of climate change requires that fossil fuels be replaced; the CO2 must be stopped from entering the atmosphere. The consensus is to build wind and solar farms to generate electricity instead of using fossil fuels. Since renewables are intermittent, there must be some way to store and supply electricity when renewables are not

2021-05-19 Renewables Plus Storage Are Outcompeting Conventional Power

From YouTube replies @Aleksandrs Naumovs I forgot to mention PPAs. The utilities are entering into power purchase agreements with solar and wind contractors for per kWh rates that are lower than conventional thermal power plants. These often include short term 4 to 8 hour storage. Any new generation has to compete against renewables plus storage

2021-05-15 Million Mile Battery Is Not Moot Or Irrelevant

From FB group TSLA Shareholders De Bits Said, “…analysts … are focused on million mile battery which is moot if not irrelevant.” To you, Mr. De Bits, it may be irrelevant because you are apparently clueless about how important the lives of batteries are going to be for the V2G – vehicle to grid –

2021-05-07 Relithiation To Make Old Batteries Like New

If the old cells were made easier to take apart and reassemble it would be helpful. I think that someday the battery makers may do what Eagle Picher did for batteries on spacecraft. There is a container of electrolyte inside the battery. To activate the battery a small charge blows the electrolyte out of the

2021-05-07 LAVO 30 Year Hydrogen Fuel Cell System

This short story gives the price of a Lavo green hydrogen fuel cell system as AU$35,000, I’m assuming it’s Australian dollars. It says the system is good for 30 years. https://amp.9news.com.au/article/4cb3ebca-0515-419a-b298-ee491bbccb2f Here is JHAT channel’s video about it. Skip first 2 mins. https://youtu.be/0_bTjcjqN6c A comment in the above video said this (quote): << owmid 6rgy.

2021-05-03 Storing Energy In Rocks, And Other Storage Systems

This 43 minute YouTube video is about solving renewable energy storage. It is mostly in Dutch with English subtitles. This is a very innovative pilot plant that uses basalt rock to store high heat. After the 30 minute point they interview the guy who explains that the Siemens Gamesa system they developed can replace the

2021-04-24 LADWP’s Plans For Intermountain (Coal) Power Plant

This is a .PDF document from the CPUC about LADWP’s future plans for converting the IPP coal fired power plant in Utah to a solar and wind generating facility, a green hydrogen generation and underground storage site, replacing the coal plant with CCGTs – combined cycle gas turbine generators that will run on hydrogen, and
