Solar storage batteries: Tesla Powerwall and 17 others put to the test

A good news article regarding community batteries.

ā€˜petrifyā€™ is a bit scammy.

Large energy companies can be part of it. If it amounts to nothing in the longer term then it was a small defensive investment. If it represents a genuine sea change in the way the network operates then they didnā€™t get left behind.

These have been talked about for many years. A colleague in the electricity industry I worked with moved to a company promoting similar systems about 8-10 years ago (this particular company didnā€™t succeed). The systems in this particular company he worked for had targeted design capacities or a week to a few weeks, to maintain more reliable supply to those communities at the ā€˜end of the lineā€™.
Such communities are subject to regular voltage underruns, outages etc and the batteries have the potential to stabilise supply in such scenarios. It is also reported that these types of conditions are likely to increase in frequency and duration as the network relies more on renewable generators.

Similar battery systems have also been discussed in urban areas to buffer fluctuations in supplies from renewable generation.

Fossil fuel powered generator supporters have indeed raised that, while those supporting a wider range of renewables and more of them disagree. The latter claim sufficient ā€˜renewable generationā€™ infrastructure would be as reliable as the fossil fuelled variety. He said, she said?

Oops.

If a French company cannot even manage a battery, little wonder that the scrapped submarine project was a fiasco.

No details are available in the link so we cannot guess why the failure occurred or who is responsible. No court case has been held yet but you assume them guilty. There is no link between the operators/builders of submarines and big batteries, so your comment only makes any sense if all French companies are incompetent; you can show us that canā€™t you? Or is it that evidence isnā€™t required because they are furriners?

I can attest many French companies are world leaders in their fields, yet while the British held onto the almighty shim to keep their auto manufacturing alive the French just added more and more parts.

While I love French cars and currently have 2 Renaults, an old saw that has some truth related to life views is if the Germans can make it with 3 parts, the Americans with 4, the Japanese with 2, the French might be able to incorporate 47. The French savour and enjoy, not just treat everything like business where efficiency is the only end.

A mate who was a QF LAME reinforced the ā€˜French attitudeā€™ comparing dealing with Boeing (always happy to talk about it, including with engineering groups) and Airbus (just change the part, click). The latter might have interrupted their factory lunch, complete with wine. (Been in a French factory at lunch circa early 90ā€™s, seen that, absolutely normal at the time and still might be.)
