    They are the predicted figures for each financial year, not accumulative.

    Posted By: fostertomI'm sceptical about hydrocarbon cellulose decomposing to pure carbon - surely endothermic, so where does the input of energy come from? Why doesn't it prefer the more 'downhill' (exothermic) oxidation route (or in absence of oxygen, decomposition to methane)?
    Actually, not sceptical, just wondering how it occurs...Here's me been saying for years that it makes no difference, all organic matter decomposes by oxidising to CO2 and H2O just the same, whether burnt, composted or left to rot - only the timescale differs.

    But of course, that would mean that any compost heap would be just an inert lifeless pile with all the goodies evaporated - far from true. So obviously much (most) of the carbon gets locked into higher-embodied-energy (what's the correct term?) carbon compounds rather than deteriorating exothermically to lowest-possible-energy CO2. Same goes for forest floor.

    Hm, this changes everything - even the theoretical 'no added CO2' principle of biomass as fuel (which already is seriously flawed in practice). Obviously far better, then, to burn nothing, not even biomass. Vindication, tony! Instead either sequester it warm and dry 'forever' as building material etc, or compost it or let it rot on the forest floor.

    ... but methane as a by-product of the decomposition is a much worse 'GreenHouseWarming' gas than CO2? :confused:

    Thanks Ted. When I get a few hours spare (end of holiday season), I may try and pick this up in more detail. Seems policy is changing weekly anyway.

    Has it only just sunk in :bigsmile:

    The H2O (or water) will just evaporate normally, or seem out. If it was 100% dry matter, virtually nothing will change in the long term and it will be mostly (C) and a little hydrocarbons (CH of some flavour) and a little oxidized material (something with an O in it). There will also be other elements, but tiny amounts.
    If there is some moisture, then bacteria, fungi and critters will convert some of it to CO2, via Methane. There will also be some Sulphur compounds. That takes quite a while though.
    Not only does burning produce CO2 and particulates, it also can produce Nitrogen oxides, which are not good.

    Posted By: SteamyTeaThe H2O (or water) will just evaporate
    Sure, that's barely in the process, is just the 'sea' that "bacteria, fungi and critters" need to swim in - it's the H in the hydrocarbon cellulose that's of interest. In that mass of cellulose, you say
    Posted By: SteamyTeait will be mostly (C) and a little hydrocarbons (CH of some flavour) and a little oxidized material (something with an O in it)
    Surely no uncombined C at all, nearly all CH, and initially no oxides. Then
    Posted By: SteamyTeabacteria, fungi and critters will convert some of it to CO2, via Methane
    so where/when/how does the cellulose get converted to non-gas non-oxide high-embodied-energy C compounds, in a compost heap or forest subsoil, and where does the endothermic energy come from?

    Only taken 4 months for Amber Rudd to give her budget away to the treasury and decimate the small RE companies.
    I think she ha done herself out of a job.

    I'm sure she's doing to to ensure she gets a better job at the next reshuffle!

    Not just the small companies, Southern Solar, Mark Group and Climate Energy have all gone into administration over the last few weeks. Speaking with a local installer their bank called in the overdraft facility, fortunately they are able to survive.

    Every time I read the name 'Amber Rudd' I think it refers to an Australian brand of beer. Apologies for this slightly irrelevant comment.

    I do think that these companies are not 'going bust' but are simply getting off the gravy train before it is finally halted. Made excellent profits - now move on to the next one.

    Yes, there will be an element of that, and under our business rules it is easier and cheaper to go bust than shut down legitimately.

    In the case of Southern Solar I know this not to be true but can't comment on the other businesses. If the banks are concerned and pull loans / overdraft facilities then for most companies this would be the end as they are no longer liquid regardless whether they are profitable. The speed this has been done I believe is the main problem and their is no confidence in the Solar or even renewable market. That is the fault of Rudd who seems to be doing as much as she can to get in George Osbourne's good books.
