    Hi zoomup, are you aware that there are other sections of the forum that might suit this topic better, try the power generation section :)

    Indeed WHJ, gas still seems to be essential. Now if the methane could be captured from the big mountainous landfill site in Ghazipur in Delhi we would be laughing. It is not really a land fill site more a land rubbish mountain site. It is now 65 metres tall and methane fueled fires regularly form on it, taking days to extinguish. It grows taller by 10 metres per year. It is the size of 40 football fields. It could soon be taller than the Taj Mahal in Agra.


    About 2000 tonnes of rubbish is dumped on it every day, and there are concerns about its height. India's supreme court warned that soon red lights will have to be installed on top of it to warn passing jet aircraft.

    Hi Zoomup,


    As stated by WHJ still using other fossil fuels in the form of gas: "on average gas made up nearly 40% of Britain's suppliers" ( BBC News).

    With the issue of fracking causing controversy, coal is around for a little while, but the government has agreed to be coal free by 2025.


     Drax power station is still a big feeder,: " Two thirds of the power station can now produce renewable electricity – with just two coal generating units remaining" https://www.drax.com/press_release/drax-closer-coal-free-future-fourth-biomass-unit-conversion/https://www.drax.com/press_release/drax-closer-coal-free-future-fourth-biomass-unit-conversion.


    Regards

    Anyone know how much coal is used keeping coal fired power stations on standby and how long it takes to power up a coal fired station from cold and from hot?

    Ghazipur  is a very interesting example, as it (and the other dumps around Dehli) has a relatively new waste to energy program that is essentially an incinerator and generator, making ~ 12 Megawatts output, for  ~ 1500- 2000 tonnes of rubbish per day. This is not doing much in terms of reducing the original pile, but is at least reducing  some of the incoming material to a smaller volume of less offensive ash, and supplies some power on the side.

    If could be better if burnable rubbish was presorted, but there is no effective city wide separation of rubbish (unlike the brown bin black bin type of schemes we have in the UK) and this is exacerbated by a historical culture system that seems to encourage the upper classes who create the bulk of the mixed waste to think the problem of sorting it by type belongs to the lower classes who should collect and sort through it, but really sorting at source would be better.

    It also makes you realise that while things are not perfect here, there is scope for a lot bigger problems.

    I gather that methane is being collected from a number of old land fill sites in the UK (partly as it's useful, partly because if it's left there it tends to seep underground to neighbouring properties and do no end of damage - e.g. persistent underground fires) - also from sewage works (traditionally they generated enough electricity to run all their on-site equipment) - but the scale is small compared with what we're currently dragging out from under the North Sea (or shipping in from the far east).
