Tesla Megapack Battery Caught Fire At PG & E Substation In California
The title of this post, is the same as that of this article on CNBC, which was published in September 2022.
The article starts with these three key points.
- A Tesla Megapack caught fire at a PG&E energy storage facility in Monterey, California on Tuesday.
- The fire caused road closures and shelter-in-place orders for residents nearby.
- Richard Stedman, an air pollution control officer for the Monterey Bay Air Resources District (MBARD) said in general lithium ion battery fires can emit toxic constituents like hydrochloric and hydrofluoric acid.
The article goes on to say, that there were no power outages and no on-site personnel were injured.
In the late 1960s, I worked for ICI at Runcorn.
One of the instruments, I helped to develop was a detector for water in bromochlorodifluoromethane or BCF, as it is commonly known.
- You may have seen BCF on a fire-extinguisher, as that is the chemical’s main use.
- In those days, ICI made BCF on a plant that also manufactured the anaesthetic; Fluothane.
- The plant was in Rocksavage works by the Mersey.
It should be noted, that Rocksavage works had one of the best safety records in the whole of the company.
When the instrument was ready, I was told to go to the plant and see Charlie Akers, who was the foreman electrician on the plant. He would arrange fitting the instrument to the plant.
- Charlie was a short stout man and the first thing he did was to get a proper mug out of a box of perhaps two dozen new ones and write my name on it.
- He then made us both mugs of fresh tea with fresh milk from a bottle.
- He said something like. “Now you’ve got no excuse to come and see me before you go on the plant or have any questions!”
- He also said that everybody, who worked in Rocksavage was very proud of its safety record and proceeded to give me a tour of the plant pointing out its hazards.
One lesson, I learned that day and still do was to walk up stairs in a hazardous environment using the stanchions of the rails. You never know what has fallen on the handrails. On the BCF plant this could have been hydrochloric and hydrofluoric acid.
- At one point to illustrate the danger of the latter, he took a pair of tweezers and put a spec of hydrofluoric acid (HF) dust on the tip of my finger, which was painful.
- He also said that HBr was a lot more dangerous.
I didn’t disgrace myself on that plant and the lessons, I learned that day have stayed with me all my life. I even think, that they have had positive effects on my stroke recovery, as I was given tips about how to get out of a chemical plant, after a fire or serious spillage.
Thank you Charlie!
One of the key points in the CNBC article, is that lithium-ion battery fires can emit hydrochloric and hydrofluoric acid.
It makes me wonder, if our high levels of usage of these batteries for where there is an alternative is a good idea.
Gore Street Energy Storage Fund’s Portfolio Increases To Over 1GW
The title of this post, is the same as that of this article on the Solar Power Portal.
By any measure a GW is a substantial amount of power and the article gives all the figures for the fund.
One thing, I feel, I can say, is that large grid-connected lithium-ion batteries, as deployed by Gore Street, are more reliable than the similar smaller batteries in e-bikes and e-scooters.
The media and especially the financial pages would have had a field day, if a lithium-ion battery caught fire. Certainly Gore Street and others building large batteries, don’t seem to have any planning permission problems from Nimbys.
Hydrogen ‘The Only Option’ For Metrobus Fastway ZE
The title of this post, is the same as that of this article on Route One.
This is the introductory paragraph.
Hydrogen fuel cell-electric remains the most realistic zero-emission technology for usage cases requiring very high mileage and utilisation capabilities. That is the verdict from the Go-Ahead Group after its Metrobus subsidiary launched 20 Wrightbus GB Kite Hydroliner single-deckers on 29 June.
This paragraph gives more details.
Go-Ahead Group Chair Claire Hollingsworth, who was present at the launch alongside Under-Secretary of State for Transport Richard Holden and other stakeholders and dignitaries, underlines the need for hydrogen on Fastway. “These are the most intensive routes in the Go-Ahead network,” she explains. “We need 300 miles of range and have little time to plug in.”
Let’s face it, a bus that takes a lot of time to fuel-up can’t be as efficient, as one that takes just a few minutes. Especially, if the buses are running a large number of hours per day.
The whole article is a must read and surely Go-Ahead’s conclusion to other modes of transport, that do long distances, like heavy trucks, long-distance coaches and railway locomotives.
