Los Angeles is Finally Ditching Coal -- and Replacing It With Another Polluting Fuel (latimes.com) 355

An anonymous reader shares a report: The smokestack at Intermountain Power Plant looms mightily over rural Utah, belching steam and pollution across a landscape of alfalfa fields and desert shrub near the banks of the Sevier River. Five hundred miles away, Los Angeles is trying to lead the world in fighting climate change. But when Angelenos flip a light switch or charge an electric vehicle, some of the energy may come from Intermountain, where coal is burned in a raging furnace at the foot of the 710-foot smokestack. The coal plant has been L.A.'s single-largest power source for three decades, supplying between one-fifth and one-third of the city's electricity in recent years. It's scheduled to shut down in 2025, ending California's reliance on the dirtiest fossil fuel.

But Los Angeles is preparing to build a natural gas-fired power plant at the Intermountain site, even as it works to shut down three gas plants in its own backyard. Although gas burns more cleanly than coal, it still traps heat in the atmosphere. It also leaks from pipelines as methane, a planet-warming pollutant more powerful than carbon dioxide. Critics say Los Angeles and other Southern California cities have no business making an $865-million investment in gas, especially when the state has committed to getting 100% of its electricity from climate-friendly sources such as solar and wind. L.A. Mayor Eric Garcetti has touted his decision to close the three local gas plants as part of his own "Green New Deal" to fight climate change.

          The Molten Salt Reactor [wikipedia.org] design would be much better suited for areas like California.

          The biggest problem with the current Light Water Reactor [wikipedia.org] design in an Earthquake zone is the risk of a cracked cooling pipe and resulting loss of pressure or losing power to the cooling pumps.

          MSR's don't have those issue, the coolant is under much lower pressure, the molten salts themselves would plug any leaks and the core design would allow for a passive shut down system in the result of power to the cooling systems.

          I personally would have no issues with a MSR being built in my City, though I would strongly advocate that it use a Thorium fuel cycle over a Uranium based one.

      It isn't free, but the losses over 500 miles aren't bad at sufficiently high voltage. Quebec is geographically large, and the power is primarily generated in the north, so Hydro Quebec has 11,422 kilometres of 735 and 765 kilovolt transmission lines. Electricity has to travel nearly a thousand kilometers to get to Montreal. The transmission losses are only a few percent. Of course, we do it like that because of geographic restrictions: hydro dams have to go where the rivers and reservoirs are.

    A power grid needs SOMETHING to generate power when renewables don't meet demand. When everyone in LA turns on the AC during the summer, you can't meet this with just wind or solar. You can scream batteries all you want, but wind and solar still only produce so much, and the batteries can run out.

    Natural gas gives off HALF the CO2 per unit energy generated vs big bad coal. These so-called "environmentalists" (really more like hard-liner extremists) need to realize that they can't demand perfection.

      It's L.A. the sky is clear and sunny during a heat wave. That's when you have peak demand.

      There is something to be said about having a higher capacity infrastructure, where the city can temporarily access power from far away at a significant cost that may be fossil fuel. The base line power needs to come from renewable resources and needs to be local and ideally cheap. If they can run on renewable energy for 90% of the day for 300 days a year, that would be huge. It's a fallacy to assume that it's a non-starter if the problem isn't 100% solved by one solution.

      What is needed is a web of redundant and supporting systems that solves the multi-dimensional problem of base line versus peak demand. Politically it's probably impossible to accomplish in L.A. when setting up wind farms outside of the city triggers multiple anti-development activist groups. It's NIMBYism combined with overreaching, ill-conceived environmentalism.

      It's not all bad news. Solar panels work very well in the area. And people get panels installed once they figure out how to finance them. I have far fewer sunny days than LA and I save a ton of money, mostly because I have similarly insane rates.

        I live near the Geysers in NorCal and it's definitely not "the solution". First, it generates an ongoing micro-quake swarm that's easily visible on the USGS quake site. Most of them are 2s and 3s, but occasionally a larger tremor happens. People who lived near there complained for years about slow damage to their houses. Until a wildfire swept through, it was their biggest environmental concern. It's a rural area, so few people are affected.

        On cold days, the steam plumes from the plant are visible for miles around. This is a minor aesthetic concern.

        Finally, vents can shift or become exhausted in various ways. Finding clean water to pump into the holes and maintaining good steam quality can be an issue.

        Don't get me wrong. The Geysers plant is a valuable addition to our grid, but it's not a silver bullet that will work everywhere in the state.
