Turning to the substance of the news item,
"According to SMM statistics, the global energy storage system shipments in 2023H1 reached 72.4 Gwh. China’s shipments were 47Gwh, accounting for 65%; overseas shipments were 25.4Gwh, accounting for 35%; global energy storage system shipments were still dominated by Chinese integrators. Tesla’s shipments in the first half of the year exceeded 7Gwh, ranking first in the world."
This is an area that is desperately short of good data in either the public domain or in proprietary reports. Over the years I have put together a table of what I think the shipments were, plus my own forecast, but I have always been concerned about the possibility of significant under-reporting of actual shipments for all sorts of reasons. The news item is most useful and shows how industry/media are taking the topic more seriously, and can usefully be compared with my
previous historical & forecasts.
The most obvious thing is that they (SMM) are suggesting 2023-H1 shipments were 72 GWh, which implies it will likely be approx 150 GWh for the full year. In comparison my forecast was only 47 GWh, so I now tend to think I have been undercounting in the past as it is not credible that volumes leap from 30 GWh to 150 GWh in one year. Also the SMM data includes 7 GWh attributed to Tesla which corresponds well with Tesla's Q1+Q2 public reports of 3.9 + 3.6 = 7.5 GWh and in turn suggests that the SMM data is reasonably solid. Looking at the list of companies and the corresponding volumes also suggests to me that the data is reasonably reliable.
The language (Chinglish) is slightly ambiguous but looking at the company list and the volumes I am fairly sure that there is no doublecounting of vehicle mobility product going on. These volumes appear to be purely stationary storage, for a combination of consumer-scale and utility-scale usage. Confusingly this also gets termed domestic storage so one needs to be careful about terminology.
The implication is that stationary market is aready taking approx one quarter of the volume versus the vehicle market, i.e. FY 2023 will be approx 150 GWh vs 626 GWh, approx. This is great news in terms of overall stationary storage adoption/scaling/deployment and further suggests to me that we are significantly underestimating the speed of the transition. I did not think that the (historical data + my projections) stationary market would reach that relative fraction until approx 2030.
Again this is the
previous forecast I had, which I now think I will have to very substantially revise.
Does anyone have access to the SMM historical data to compare with my own scrapings of the various datapoints I have amassed out there, which now seem to be confirmed as a significant under-count ?
Oh, and by the way, this is another new-world industry where Chinese dominance is fully-locked in. It also happens to be one that is of vital strategic importance for the Chinese in their internal use as well as for Chinese exporting.
