No, but I can't remember a time when a solar panel blew up and killed someone. Batteries have killed a few... but compare that to the thousands dead in O&G. Well designed solar fields should only have external risks. O&G seems to have both internal and external risks (both are on topic as it's risk assessment). 1 Quote Share this post Link to post Share on other sites

So a train derails hauling oil is an oil & gas disaster? If it would have been hauling cattle would it have been a ranching disaster? You are obviously in crowd that termed the Exxon Valdez a oil (exploration/production) disaster instead of a transportation/shipping disaster. If the Exxon Valdez had been hauling milk (which deoxygenates water), would it have been a dairy industry issue? Quote Share this post Link to post Share on other sites
butasha + 123 BR July 7, 2019 2653 acres of land to produce 400mw and this article states this is 7% of the LA load during daylight hours. This facility is over 4 square miles of real estate. Just imagine how much land it will take to cover the remaining 93% load covered by thermal generation. I don’t know the actual foot print of a modern 400 MW combined cycle has generator is but my guess would 50-100 acres. Additionally if LA was able to go completely renewable energy they would have to contract with some entity for spinning and non-spinning emergency power in the event this green power was interrupted. Has the real-estate, emergency backup power and probably other unnamed issues been included in this less than 2cents/kWh rate? Before the green religion types get all bent out of shape I am not trying to knock this concept. I just a few questions on what the next steps will actually be. 1 Quote Share this post Link to post Share on other sites

Before the green religion types get all bent out of shape I am not trying to knock this concept. I just a few questions on what the next steps will actually be. The Nevada (nuclear) test site (just northwest of Las Vegas) is about 80 miles by 80 miles, or 6400 square miles. This is the surface area required to power the whole country with solar at 20% conversion efficiency. One doesn't have to look far to see 'four square miles' covered by farmland. Covering 4 square miles of desert would appear to be incidental in comparison. Solar covers 'surface area'. Storage consumes 'volume'. If one assumes that the greater LA area is roughly 18 million people, this would be roughly 7.5 million households. Were one to assume 30Kwh of storage for each household, one would need 225,000,000 Kwh per day for the households. Using LiFePO4 at 120 watt-hours per liter, the volume is 1,875,000,000 liters. There are one thousand liters in cubic meter (10 x 10 x 10), so this translates to 1,875,000 cubic meters. If a 'battery bank were 10 meters (30 feet) high, then it's footprint would be 187,500 square meters. The square root of 187,500 is 13,693, so one side of this bank would be roughly 13.4 kilometers or 8.2 miles on a side. While this looks like a lot, it's still tiny compared to the real estate torn up by coal mines (sometimes 60 miles in extent) or the tank farms one finds in places like the Henry or Cushing hubs. Since most power plants are more than 30 feet high, battery storage could well occupy higher buildings with more compact footprints. I suspect that lithium would not be an economical storage resource at that scale - perhaps salt water or sodium ion batteries would make more sense.

Yes, I include shipping it because of its hazardous properties (flammability, toxicity). If a rail car full of ammonia or pesticide blows up that is only being moved because a farmer ordered it - why not attribute at least some of the damage to the agriculture industry?
