2020-09-25 Anaheim Will Get Electric Buses

The electric vehicle revolution is already happening. Hopefully it will occur much quicker that 2035, which is when Gov. Newsom has signed a law mandating all new vehicles sold must be zero polluting. The only problem is people are avoiding mass transit systems because of CoVID19. I’ve read that ridership is down. That should change

2020-09-21 Hydrogen Fuel Cells V. Battery Electric Vehicles

My take in a comment >> @mfhberg Said, “[Hydrogen Fuel Cell vehicles] will die…” Right now, it looks like Toyota’s Mirai, Hyundai and Honda all have a sizeable stake in the HFC market future. These are not backyard grease monkeys, these are car companies that have done a lot research and development. Toyota has had

2020-09-12 Hydrogen Fuel Cells Add Excessive Complexity, Cost

This doesn’t seem to be good for Toyota FCEV, Honda FCX or Hyundai. Toyota has been making FCEVs for more than 2 decades. It would seem they would know what the realities were and are regarding FCEVs. The Honda FCX Concept in 1999 and FCX Clarity from 2008. The future of heavy vehicles, trains airplanes

2020-09-11 Nikola Fraud Investigation

This doesn’t look good. GM just agreed to exchange $2 Billion of Nikola stock for services rendered in making the Badger (truck) EV. Hindenberg claims Nikola is a scam https://www.businesswire.com/news/home/20200910005912/en/Law-Offices-Frank-R.-Cruz-Announces-Investigation Nikola fights back. https://mobile.reuters.com/article/amp/idUSKBN2621WR

2020-09-10 Model Of Least Cost All Renewables Grid

This is supposed to be a least cost model. Solar reaching up to 4.3 times capacity. I would expect that much of the curtailment would be replaced by “flexible loads” controlled by the grid, most of which would be hydrogen generation. The hydrogen could be stored and used for longer term storage/generation and/or transportation fuel.

2020-09-08 Nikola GM Partnership; Hydrogen

From my comments. From what I’ve seen, Nikola is really trying to get rolling with heavy trucks with hydrogen. That’s where Milton doesn’t have to compete with Tesla. The badger pickup with batteries is kind of a hard sell because it will be competing with Tesla, and that’s nearly an impossibility without some biggie like

2020-09-05 Ammonia To Hydrogen For Fuel

This 2017 article is on a website dedicated to ammonia as a the mechanism for transporting hydrogen to be used as fuel. There is a large amount of hydrogen made into ammonia for fertilizer, so it’s an established industry. But this uses methane AKA natural gas as the source for the hydrogen, so it is

2020-09-04 Power Outages Caused By Misoperations

This graph is for thevwestern US, I think it said 80 million population. The Misoperations is explained in the text. I noticed that most of the problems seem to be with microprocessors. That must mean there are bugs in the systems. Maybe hardware? Or if the hardware is redundant, then probably software? https://www.wecc.org/epubs/StateOfTheInterconnection/Pages/Misoperations0706-4202.aspx

2020-09-03 Distributed Generation And Islanding

There is a lot of concern for safety when DGs (distributed generators) are connected to the power grid. The grid operators must ensure that none of the DGs feed back into the grid when the grid generator is not operating. They go through several scenarios in this article. https://electrical-engineering-portal.com/protection-impacts-intentional-islanding-distributed-generation From what I see the DG
