2022年6月2日 · In this paper, we model all major RNG pathways using a single, consistent framework. This work is a life cycle assessment (LCA) of three RNG pathways with multiple feedstocks and technologies. The three pathways evaluated are anaerobic digestion (AD), thermal gasification (TG), and power-to-gas (P2G).

2023年2月15日 · Renewable natural gas (RNG) can be produced from landfill gas, wastewater sludge, and animal waste. Triple bottom line performance of waste-derived gaseous fuel was assessed using LCA and LCC. Animal manure-derived RNG production provides the best environmental performance.

2021年8月15日 · In this study, we evaluate the life cycle greenhouse gas (GHG) emission reduction benefits of renewable natural gas (RNG) and lactic acid (LA) production from four types of wet waste feedstocks (wastewater sludge, food waste, swine manure, and fats, oil, and grease [FOG]) via anaerobic digestion (AD) and LA fermentation, respectively.

2024年5月22日 · The study conducts a LCA following the principles outlined in ISO 14040 and ISO 14044 (Finkbeiner et al., 2006) to understand the emissions associated with the RNG produced from AD and upgrading. LCA is an established method for evaluating the environmental impact of systems and processes (Finkbeiner et al., 2006 ).

LCA of Tucker RNG technology for producing syngas and biochar from forest and sawmill residues and estimated the primary energy con-sumption and environmental impacts in a holistic life cycle starting from raw material extraction. In this study, pyrolysis and thermochemical conversion were used interchangeably because

2024年1月23日 · RNG, derived from organic waste sources through anaerobic digestion, serves as a potent force in decreasing carbon emissions (methane). By displacing fossil-based gas, RNG becomes a catalyst for transforming waste materials, both from food and animal sources, into a valuable resource.

LCA quantifies high powertrain efficiency and low -GHG fuels in transportation decarbonization Current (2020) and Future (2050) GHG performance shows reductions due to both technology advancement and fueling GHG intensity. Battery technology progression a major influence in GHG reductions seen in BEVs.

2021年5月27日 · In this study, we evaluate the life cycle greenhouse gas (GHG) emission reduction benefits of renewable natural gas (RNG) and lactic acid (LA) production from four types of wet waste feedstocks (wastewater sludge, food waste, swine manure, and fats, oil, and grease [FOG]) via anaerobic digestion (AD) and LA fermentation, respectively.

2024年2月22日 · This article presents a framework that focuses on structural considerations within gas networks to evaluate and rank various feasibility options for renewable natural gas (RNG) cases. Specifically, the analysis examines and compares a range of methods for producing RNG using natural gas from waste (NGFW), considering different types of waste as ...

2022年9月20日 · A life cycle assessment (LCA) of the RNG production process was performed. A comparative study showed that the proposed process is capable of reducing the emissions by 70% in comparison to a biomethane production via High Temperature Water Scrubbing of biogas.
