Re: Coal matters
More coal power generation closed than opened around the world this year,
China continues to increase its coal power, but in India new construction has ground to a near halt
The size of the global coal power fleet fell for the first time on record over the first six months of the year, with more generation capacity shutting than starting operation.
Global Energy Monitor, a US research and advocacy group that tracks fossil fuel development, found the closure of coal generators closing, mostly across Europe and in the US, outstripped stations being commissioned, largely in Asia.

Re: Coal matters
National Grid fires up coal power station for first time in 55 days
Heatwave brings wind turbines to standstill and causes gas plants to struggle
https://www.theguardian.com/business/20 ... in-55-days
So, another year, a few more solar farms, and coal is dead.

Re: Coal matters
Interesting chart in the Telegraph today, showing how the mix of UK energy-generation has changed between 2012 and 2020 -

Re: Coal matters
Most of the 'Other' which has replaced coal is biomass. How much better is it than the coal it replaced?

It is worth reading the ONS note on this
https://www.ons.gov.uk/economy/environm ... 2019-08-30
Renewable and waste sources" category includes Hydroelectric, Wind, Wave, Tidal, Solar photovoltaic, Geothermal aquifers, Landfill gas, Sewage gas, Biogas from autogeneration, Municipal solid waste (MSW), Poultry litter, Straw, Wood, Charcoal, Liquid bio-fuels, Bioethanol, Biodiesel and other Biomass. "
This is why I haven't answered whoever was quibbling about trying to keep the lights on yet, as I don't have time to dig into the biomass segment to calculate all the red stuff. Basically a lot of biomass is indeed US forests (here's looking at you, Drax), but a lot of the other stuff is UK-based biomass wastes which is quite another matter.
Anyway, I'm busy at work right now so must keep going. Looking out over the post-consumer waste biomass power station outside my office window .....

Re: Coal matters
Thanks dspp, I did look at the ONS site but thought it may be one link too many.
Biomass from the States provides quite a lot of work for my business, certainly more than the coal it replaced.
I presume this is because they are burning a lot more of the biomass to produce the same amount of energy?, and with that in mind I wonder if the pollution statistics adequately reflect the extra that is burnt, and is not simply a ton by ton comparison.
So my head says 'ker-ching', but my heart isn't so sure.

Re: Coal matters
A research reporton SIMEC Atlantic's proposed Uskmouth conversion project has some details on p35.
in this case they're burning pellets made up of 50% paper, 50% plastic. They say (for a 220MW plant) coal creates 2.3m tonnes of CO2, these pellets create 1m (and gas is 0.7m). Waste incineration is typically much less efficient as they take little of the high-calorific waste because they prefer to earn money from gate fees than generation, and their boiler design means if they take a lot of high-calorific waste they cannot process as much other waste, and thus is less profitable for them (p27). The electricity generation is a bonus for them, not their main business. (and no, I didn't know that either!)
So its difficult to say what the emissions from biomass as - because the biomass can be all kinds of things, not just forestry offcuts. And then EU rules on CO2 emissions from wood count differently as they're a kind of sustainable pollution. I suppose in the end it depends if the biomass is being created anyway, you might as well burn it. No point sticking it in a hole and letting it rot (or burn whilst underground anyway)

Re: Coal matters
Coal think they are flat until 2025 ......
https://www.iea.org/reports/coal-2020
"Coal 2020 highlights recent global and regional trends in coal demand, supply and trade, and an outlook to 2025.......Global coal consumption is estimated to have fallen by 7%, or over 500 million tonnes, between 2018 in 2020. A decline of this size over a two-year period is unprecedented in IEA records, which go back as far as 1971. Based on the assumption of a global economic recovery in 2021, we expect both electricity demand and industrial output to increase. As a result, we forecast a rebound in global coal demand of 2.6%, led by China, India and Southeast Asia. Higher natural gas prices and electricity demand are set to slow the structural decline of coal use in the European Union and the United States, which both might see their coal consumption grow for the first time in nearly a decade. By 2025, global coal demand is forecast to flatten out at around 7.4 billion tonnes."

Re: Coal matters
Can’t recall precise details, but overnight I was listening to the World Service and heard that some Japanese company which paid £900m for a less than ten-year-old coal-fired plant (in Australia?) has written the value of the ‘asset’ down to zero in its latest accounts.

Re: Coal matters
(Reuters) - China’s effective ban on imports of Australian coal is forcing a realignment of flows between the world’s two biggest importers and two largest exporters.

Re: Coal matters
Australia switches to India
"China has placed an effective ban on imports from Australia, the world’s largest exporter of coking coal used to make steel, and the second-biggest shipper of thermal coal used in power plants.
China is unhappy with Australia over a range of issues, including Australia’s call for an international investigation in the origins of the coronavirus and China’s response to the initial outbreak.
This has led to a series of trade actions by China against Australia, including bans or tariffs on coal, barley, some meat, wine and tourism, among other items.
Ironically, China is spending more than ever on imports from Australia, given its reliance on iron ore and liquefied natural gas, two commodities commanding high prices and for which Australia is the world’s largest exporter.
But while Australian coal exporters have been shut out of China, they have been making inroads in India, with imports from Australia hitting a record high 6.75 million tonnes in January, according to Refinitiv.
This was up from 6.32 million tonnes in December, 5.06 million in November and 5.49 million in October.
Cumulatively, the past four months have been the strongest for Indian imports of Australian coal since Refinitiv started assessments in January 2015."
