ʻO UK ka ʻāina mua loa o ka honua e hoʻokō i ka mana o ka mana o ka lanahu, a ʻo ia wale nō ka ʻāina i hoʻokō i ka hoʻololi ʻana mai ka nui o nā mea hoʻoulu mana lanahu me ka biomass-coupled power generation a hiki i ka lanahu nui- nā mea kanu mana me ka 100% wahie biomass maʻemaʻe.

I ka makahiki 2019, ua hoʻemi ʻia ka nui o ka mana lanahu ma UK mai 42.06% i 2012 a i 1.9% wale nō. ʻO ka paʻa ʻana o ka mana lanahu i kēia manawa ma muli o ka hoʻololi paʻa a me ka palekana o ka pā, a ua hōʻea ka mana biomass i ka 6.25% (ka mana biomass China ʻO ka nui ma kahi o 0.6%). I ka makahiki 2020, ʻelua wale nō nā mea kanu i puhi ʻia i ka lanahu (West Burton a me Ratcliffe) i waiho ʻia ma UK e hoʻomau i ka hoʻohana ʻana i ka lanahu i wahie no ka hana mana. I ka hoʻolālā ʻana o ka mana mana Pelekania, e helu ʻia ka mana biomass no 16% i ka wā e hiki mai ana.

1. ʻO ke kumu o ka hana mana biomass-coupled ma UK

I ka makahiki 1989, ua hoʻolaha ʻo UK i ka Electricity Act (Electricity Act of 1989), ʻoi aku ma hope o ke komo ʻana o ka Noe-Fossil Fuel Obligatio (NFFO) i loko o ka Electricity Act, ua loaʻa i ka UK kahi hoʻonohonoho piha piha o nā kulekele hoʻoikaika hou a me ka hoʻopaʻi ʻana. hana ikehu. Ua koi ʻia ʻo NFFO ma o ke kānāwai e koi aku i nā mea kanu mana UK e hāʻawi i kekahi pākēneka o ka ikehu hou a i ʻole ka ikehu nuklea (non-fossil energy power generation).

I ka makahiki 2002, ua pani ka Renewable Obligation (RO) i ka Non-fossil Fuel Obligation (NFFO). Ma ke kumu kumu, kāpae ʻo RO i ka ikehu nuklea, a hoʻopuka i nā hōʻaiʻē hōʻaiʻē Renewable Obligation (ROCs) (Note: e like me China's Green Certificate) no ka uila i hāʻawi ʻia e ka ikehu hou e hoʻokele a koi ʻia nā mea kanu Power e hāʻawi i kekahi pakeneka o ka mana ikehu hou. Hiki ke kūʻai ʻia nā palapala hōʻoia ROC ma waena o nā mea hoʻolako mana, a ʻo kēlā mau hui hana mana i lawa ʻole ka ikehu hou e hana ai i ka uila, e kūʻai paha lākou i nā ROC keu aku mai nā hui hana mana ʻē aʻe a i ʻole e kūʻē i nā uku aupuni kiʻekiʻe. I ka wā mua, ua hōʻike ʻia kahi ROC i hoʻokahi kaukani degere o ka mana ikehu hou. Ma ka makahiki 2009, e maʻalahi ka ROC i ka ana ʻana e like me nā ʻano ʻenehana hana mana ikehu hou. Eia hou, ua hoʻopuka ke aupuni Pelekāne i ka Energy Crop Scheme i ka makahiki 2001, e hāʻawi ana i nā kōkua no ka poʻe mahiʻai e ulu i nā mea kanu ikehu, e like me nā kumu lāʻau ikehu a me nā mauʻu ikehu.

I ka makahiki 2004, ua ʻae ʻo United Kingdom i nā kulekele ʻoihana kūpono no ka paipai ʻana i nā mea hoʻolahu ahi nui e hana i ka hana mana biomass-coupled a hoʻohana i ka wahie biomass e ana i nā haʻawina. Ua like kēia me kekahi mau ʻāina ʻEulopa, akā ʻokoʻa mai nā haʻawina kālā a koʻu ʻāina no ka hana mana biomass.

I ka makahiki 2012, me ka hoʻonui ʻana i nā hana biomass, ua hoʻololi ʻia ka mana o ka mana biomass-coupled ma United Kingdom i nā mea kanu ahi ahi nui e puhi ana i ka 100% wahie biomass maʻemaʻe.

2. Alanui ʻenehana

Ma muli o ka ʻike a me nā haʻawina o ka hana mana biomass-coupled ma ʻEulopa ma mua o 2000, ua hoʻohana ʻo United Kingdom i ka biomass-coupled power generation i ke ala ʻenehana hoʻopili ʻana. Mai ka hoʻomaka ʻana, lawe pōkole ʻo ia a hoʻolei koke i ka biomass mua loa a me ka hāʻawi ʻana i ka lanahu. ʻO ka wili lanahu (Co-Milling coal mill coupling), i ka biomass direct combustion coupling power generation generation of coal-fired power plants, nā mea a pau e hoʻohana i ka ʻenehana Co-Feeding coupling a i ʻole Dedicated burner furnace coupling technology. I ka manawa like, ua kūkulu pū ʻia kēia mau mea hoʻolale ahi i hoʻonui ʻia i ka mālama ʻana, ka hānai ʻana, a me ka hānai ʻana i nā wahie biomass like ʻole, e like me ka ʻōpala mahiʻai, nā mea kanu ikehu, a me nā ʻōpala ululāʻau. Eia nō naʻe, hiki ke hoʻohana pono ʻia ka hoʻololi ʻana o ka mana hoʻoheheʻe biomass i hui pū ʻia me ka lanahu nui i nā boiler, nā mea hoʻoheheʻe mahu, nā pūnaewele a me nā mea kanu mana ʻē aʻe, nā mea kanu mana, nā hana hana a me ka mālama ʻana, nā hale hana a me nā mākeke mana, etc. ., hiki ke hoʻomaikaʻi maikaʻi i ka hoʻohana ʻana i ke keʻena. ʻO ia ke kumu hoʻohālike maikaʻi loa no ka hoʻololi ʻana a i ʻole ka hoʻololi ʻāpana mai ka lanahu a hiki i ka hana mana biomass.

3. E alakaʻi i ka papahana

I ka makahiki 2005, ua hōʻea ka mana o ka mana biomass-coupled ma United Kingdom i 2.533 biliona kWh, e helu ana no 14.95% o ka ikehu hou. Ma 2018 a me 2019, ʻoi aku ka mana o ka mana biomass ma UK ma mua o ka hana mana lanahu. Ma waena o lākou, ua hāʻawi aku kāna papahana alakaʻi Drax power plant ma mua o 13 biliona kWh o ka mana biomass no ʻekolu mau makahiki.
