Systematic and Bibliometric Review of Biomethane Production from Biomass-Based ...
Tiago, Gonçalo A. O.; Rodrigo, Naresh P. B.; Lourinho, Gonçalo; Lopes, Tiago; Gírio, FranciscoABSTRACT: Fossil fuels drive global warming, necessitating renewable alternatives such as biomethane (or renewable natural gas). Biomethane, primarily produced through anaerobic digestion (AD), offers a cleaner energy solution but is limited by the slow AD process. Biomass gasification followed by syngas methanation has emerged as a faster alternative. This review examines advancements in these processes over t...

Production of sustainable aviation fuel precursors using the oleaginous yeast R...
Saraiva Lopes da Silva, Maria Teresa; Dutra, Francisca; Gomes, Miguel; Costa, Paula; Paradela, Filipe; Ferreira, Frederico CasteloABSTRACT: Sustainable aviation fuels (SAF) obtained from renewable sources of carbon can reduce carbon dioxide emissions and contribute for mitigating climate changes. In the present study, the yeast Rhodotorula toruloides PYCC 5615 was found to be highly promising for the bioconversion of eucalyptus bark hydrolysate and the accumulation of intracellular lipids which were further thermochemically processed to b...
Integrating social aspects in microalgal biorefineries: a Product Social Impact...
Ortigueira, Joana; Lopes, Tiago; Reis, Alberto; Gírio, FranciscoABSTRACT: The ongoing climate change phenomenon requires the reduction of atmospheric CO2 concentrations. Microalgal biorefineries, which convert atmospheric CO2 into chemical energy, offer a viable alternative to fossil fuel-based industrial systems. This study assesses the social impacts of microalgal biorefineries using the Product Social Impact Life Cycle Assessment database approach, focusing on an industr...
Alternative feedstocks for high-quality biodiesel: Lipid production from eucaly...
Dias, Bruna; Lopes, Marlene; Marques, Susana; Gírio, Francisco; Belo, IsabelABSTRACT: Microbial lipids produced by yeasts from lignocellulosic biomass are a promising feedstock for the biodiesel industry, providing a renewable energy source as an alternative to traditional fossil fuels. This study investigated the potential of Yarrowia lipolytica W29 to produce lipid-rich biomass from undetoxified sugar-concentrated eucalyptus bark hydrolysate (EBH). The lipid concentrations achieved i...
Portugal Offshore Wind, Green Hydrogen, and Sustainable Fuels: Power-to-X Pathways
Simoes, Sofia; Portillo, Juan C. C.; Simões, Teresa; Estanqueiro, Ana; Catarino, Justina; Costa, Paula; Oliveira, Paula; Ribeiro Pinto, Paulo JorgeABSTRACT: Portugal has a vast coastal area and significant offshore wind resources. The country has set ambitious targets and designated specific areas for offshore wind development. Current national policies are actively encouraging investment in these projects. This report compiles the latest strategies for offshore wind and green hydrogen in Portugal. It introduces the Power-to-X (P2X) concept, explores pote...

Economia do Hidrogénio Verde: Ferramentas para o Apoio à Decisão [Poster]
Simoes, Sofia; Simões, Teresa; Quental, Lídia; Catarino, Justina; Amorim, Filipa; Brás, Teresa; Patinha, Pedro; Lopes, Tiago; Rodrigues, CarlosRESUMO: O Hidrogénio (H2) Verde perspetiva-se como um vetor energético indispensável para alcançar a neutralidade carbónica em 2050, porém a economia deste vetor está em desenvolvimento e os agentes económicos precisam de fontes de informação confiáveis e ajustadas ao contexto nacional e Europeu. Neste sentido, o LNEG desenvolve investigação em vários domínios relacionados com o H2 verde, desde o estudo e desen...
Sustainability Assessment of 2G Bioethanol Production from Residual Lignocellul...
Correia, Bárbara; Matos, Henrique A.; Lopes, Tiago; Marques, Susana; Gírio, FranciscoABSTRACT: The development of sustainable biofuels can help to reduce the reliance on fossil fuels and mitigate the impact of climate change. This study analyzes bioethanol production from agro-forestry residual biomass, namely eucalyptus residues and corn stover. The study includes process simulation using Aspen Plus software, followed by economic analysis and life cycle assessment (LCA) with the help of SimaPr...
