In addition, it provides a description of current European legislative framework and the potential biomethane business models as well as the main biogas production issues to be addressed to fully deploy these upgrading technologies. Biomethane could be competitive due to negative or zero waste feedstock prices, and competitive to fossil fuels in the transport sector and power generation if upgrading technologies become cheaper and environmentally sustainable.<\/jats:p>","DOI":"10.3390\/en14102742","type":"journal-article","created":{"date-parts":[[2021,5,11]],"date-time":"2021-05-11T10:20:36Z","timestamp":1620728436000},"page":"2742","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":79,"title":["Biogas from Anaerobic Digestion as an Energy Vector: Current Upgrading Development"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7857-3330","authenticated-orcid":false,"given":"Raquel","family":"Iglesias","sequence":"first","affiliation":[{"name":"Department of Energy, Research Centre for Energy, Environment and Technology (CIEMAT), 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1207-6275","authenticated-orcid":false,"given":"Ra\u00fal","family":"Mu\u00f1oz","sequence":"additional","affiliation":[{"name":"Institute of Sustainable Processes, University of Valladolid, 47011 Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2597-1199","authenticated-orcid":false,"given":"Mar\u00eda","family":"Polanco","sequence":"additional","affiliation":[{"name":"Institute of Sustainable Processes, University of Valladolid, 47011 Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8174-9264","authenticated-orcid":false,"given":"Israel","family":"D\u00edaz","sequence":"additional","affiliation":[{"name":"Institute of Sustainable Processes, University of Valladolid, 47011 Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9050-6870","authenticated-orcid":false,"given":"Ana","family":"Susmozas","sequence":"additional","affiliation":[{"name":"Department of Energy, Research Centre for Energy, Environment and Technology (CIEMAT), 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4131-7704","authenticated-orcid":false,"given":"Antonio D.","family":"Moreno","sequence":"additional","affiliation":[{"name":"Department of Energy, Research Centre for Energy, Environment and Technology (CIEMAT), 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1541-1262","authenticated-orcid":false,"given":"Mar\u00eda","family":"Guirado","sequence":"additional","affiliation":[{"name":"Department of Environment, Research Centre for Energy, Environment and Technology (CIEMAT), 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3309-4889","authenticated-orcid":false,"given":"Nely","family":"Carreras","sequence":"additional","affiliation":[{"name":"Department of Environment, Research Centre for Energy, Environment and Technology (CIEMAT), 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4326-2185","authenticated-orcid":false,"given":"Mercedes","family":"Ballesteros","sequence":"additional","affiliation":[{"name":"Department of Energy, Research Centre for Energy, Environment and Technology (CIEMAT), 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,11]]},"reference":[{"key":"ref_1","unstructured":"EC (2016).
