    Which biomass solutions help climate (few and small), and which make it worse (the ones currently large-scale/subsidised)?

    Wot tony's been saying all along, and people got chucked off GBF because it's been ideological. 'Out-there' wide consensus is growing as to which faction was right all along.

    I've only skimmed and read some highlights, but from what I see, I'm glad to see this kind of report finally published. Lets hope is gets the attention it deserves although our UK government isn't going to like it much, nor is Drax. Historical patterns of scaled use of biomass also support the report and damaging evironmental consequences of large scale reliance on biomass - I'm always bemused by how policymakers ignore history.

    The greater problem for me is that the way we've constructed our current social, economic and political systems, etc. we're backing ourselves into a rather uncomfortable corner with regards to energy and resource use. There's also the particularly evidence of willful blindness by our current government and near future leaders about this situation where they're even speaking of further investment in North Sea oil and gas and fracking....

    The UK's primary legislation is the 6th Carbon Budget under the Climate Change Act, which is based on research and consultations by the Climate Change Committee during 2018-20

    Their research on the role bioenergy should play in the 6th CB, came up with these conclusions, which is the nearest I've seen to a UK government position on biomass:


    "Do not provide further [ie post 2027] policy support... to large-scale
    biomass power plants that are not deployed with CCS technology.

    "Phase out biofuel use in cars and vans in the 2030s.

    "Support deployment of aviation biofuels up to 10% of total aviation fuel demand by
    2050, ensuring all aviation biofuels are produced with CCS

    " In industry... no long-term use of biomass as a
    fuel, unless in combination with CCS.

    " Limit support for bioenergy use in buildings to biomethane produced from
    anaerobic digestion [from domestic waste]"

    https://www.theccc.org.uk/publication/biomass-in-a-low-carbon-economy/

    There's a lot more stuff about increasing carbon stored in land uses, and introducing sustainability limitations on biofuel/biodiesel/biomass imports.

    But the CCC is not the government....nor does it actually set policy.

    Unfortunately the CCC recommendations are verging on fairytale due to CCS. In addition, its statements on forestry practise do not reflect large scale forestry practise as it is today beyond our borders.

    The UK does not hold its own stocks of biomass, especially if considerating biomass derived from forests. However, it could harvest more biomass from other sources for biogas etc.

    In addition, the statement that policy should not support new large-scale biomass plants without CCS seems pretty ignorant of the wider ramifications of such biomass consumption and its poor overall efficiency.

    Drax is the best current example of current government policy. I wonder whether there have been any recent statements about phasing this out as a consequence of its environmental harms.

    https://www.theguardian.com/environment/2022/aug/11/burning-imported-wood-in-drax-power-plant-doesnt-make-sense-says-kwarteng

    "The importing of wood to burn in Drax power station “is not sustainable” and “doesn’t make any sense”, the business and energy secretary, Kwasi Kwarteng, told a private meeting of MPs this week."

    Drax have seen the writing on the wall, but
    "The subsidies are due to end in 2027, but Drax is hoping to gain new subsidies by adding carbon capture technology to its plant. "

    AIUI, Drax are the main force behind the proposed East Coast CCS cluster project

    First hit off Google:
    https://www.carboncapture-expo.com/industry_news/drax-submits-plans-to-build-worlds-largest-ccs-project-in-the-uk/
    "Drax has applied for a development consent order (DCO) for two bioenergy with carbon capture and storage (BECCS) units... The firm plans to invest Ă‚ÂŁ2bn in the facility and begin construction in 2024. "

    Government do seem to be enacting the CCC strategy, eg this published yesterday - submit your opinion!
    https://www.gov.uk/government/consultations/business-model-for-power-bioenergy-with-carbon-capture-and-storage-power-beccs

    Worth remembering that forestry biomass for electricity, is only a part of UK biomass consumption, which includes cereals and oil crops used for blending into retail petrol and diesel. Many concerns about that.

    Interesting video worth watching here;-

    Drax is a dinosaur that should have been put out of its misery with the demise of coal. I am all in favour of biomass plants but they should only be CHP plants with overal efficiency in excess of 80% and electrical efficiency in excess of 40%. Most beneficial use of biomass will be as a renewable alternative to diesel.
