Discussion Overview

The discussion centers around China's current coal supply situation, specifically the report that the country has only 12 days' worth of coal available for consumption. Participants explore various factors contributing to this situation, including overpopulation, energy production methods, and the implications of coal dependency. The conversation touches on theoretical and practical aspects of energy production and supply chain management.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Exploratory

Main Points Raised

  • Some participants attribute the coal supply issue to overpopulation, suggesting it is a primary factor.
  • Others challenge the notion that overpopulation is the sole cause, pointing out that the article mentions "multi-dimensional" reasons.
  • One participant notes that a week's supply of coal at a local power plant has been typical for decades, questioning the urgency of the situation.
  • There are claims that China imports a significant amount of coal from the US, which is contested by another participant who states that most imports come from Australia and ASEAN countries, with Vietnam being a major partner.
  • Some participants discuss China's aggressive construction of nuclear power plants and other energy sources, debating whether this will sufficiently offset the reliance on coal.
  • Concerns are raised about the environmental impact of China's coal plants, which are said to use less clean processes compared to those in Europe and the US.
  • One participant argues that the coal supply will not run out in 12 days, suggesting that the reported figure pertains to surplus stored coal lead time rather than total availability.
  • There are discussions about the implications of supply chain management and storage practices in relation to energy resources.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding the causes of the coal supply situation, the implications of the reported 12-day supply, and the effectiveness of China's energy diversification efforts. The discussion remains unresolved with no consensus on the primary factors at play.

Contextual Notes

Participants note the complexity of the energy supply chain and the potential risks associated with coal storage, highlighting that the reported supply duration may not fully represent the urgency of the situation.

CHINA only has enough coal for 12 days of consumption, three days less than a month ago, state media reported Wednesday, sounding the alarm bells over the nation's most important source of energy.

This certainly came as a shock to me.. since this situation is clearly due to overpopulation.. and my country India, suffers from the same problem. Hence, tomorrow it could be my country in the news for it's lowering energy resources...

It's clear that there can be no other major factors? Even the article said the reasons were "multi-dimensional".
 
The power generation plant closest to my home has at most a week's supply and has run that way for decades except when strikes have threatened. Why the alarm? Twelve days is a lot of coal to store.
 
China imports a lot coal from the US.

Although 70% of China's electrical energy is produced by coal, they have an aggressive program to build about 40 or so nuclear power plants, but these take about 5 to 6 years to bring online - assuming one can get the large forgings, e.g. RPV and steam generators, built on schedule.

Not really. Over 80% of their coal imports come from Australia and ASEAN countries. Vietnam is their single largest import partner, accounting for about half of China's coal imports. Also, China exports almost as much coal as it imports. It was a net exporter until just last year.

They have aggressive programs to build pretty much *all* types of power plants. A new coal plant goes online in China every two weeks. As a result of this, the percentage of Chinese power generated by coal is expected to *increase* slightly over the coming decades. 40 nuclear power plants is, unfortunately, not even close to enough to keep up with growth in demand. On top of that, almost all of their coal plants use dirty pulverization processes, instead of the cleaner gasification and liquifaction processes used in, for example, Europe and the US.

Not really. True, coal consumption is increasing, but because aggressive building of nuclear, wind, solar, and those monstrous hydro projects the actual percentage of coal is expected to go down somewhat.
 
The Chinese coal supply will not run out in 12 days as some may presume. There is more on the way. It is their surplus stored coal lead time that is down.

Most of Americas bulk storage of gasoline could be used up in a short period of time, probably less than a month. I can't seem to find a link.

The only bulk storage of crude oil is in the National Strategic Reserve for the military.

Well, I haven't been able to find a good reference that says either way, but everything I've read has indicated that the expansion in coal power is at least as aggressive as the expansion of other types of power. We're talking about a new coal power plant every week or so, for years on end.
 
Wow, if only the coal and other industries were intertwined, then perhaps the communists could be convinced to show a little more respect towards our laws of business.

That brings up an interesting point. It really depends on where in the supply chain you make the cut, from tankers put to sea, to what's left in our collective gas tanks. The closer to the consumer the shorter the backlog. "Lean" business practices expound the virtues of limiting storage and backlog to it's minimum.

Yes, that is correct. And, coal can't simply be piled up and left till it's needed; it at least represents a significant fire hazard unless it's ventilated, turned, compacted, on a regular basis. So, twelve days doesn't sound so dire, but it all depends on the lead time (especially the variability) in their supply chain.
