Hydrothermal carbonization: Sustainable pathways for waste‐to‐energy conversion and biocoal production

GCB Bioenergy, Journal Year: 2024, Volume and Issue: 16(6)

Published: May 15, 2024

Abstract Hydrothermal carbonization (HTC) technology emerges as a sustainable method to convert wet biomass, including food waste and municipal solid into high‐energy dense biocoal. This process, conducted at temperatures ranging from 180 260°C pressures of 10–50 bar, effectively transforms the organic material in biomass solid, liquid, gaseous outputs. The product, biocoal, possesses high carbon concentration heating values on par with lignite coal, presenting cleaner alternative traditional fossil fuels. Despite operational commercial‐scale HTC facilities globally, further adoption across various feedstocks can improve management energy production. process achieve yields up 80%, particularly favoring generation secondary char higher values. not only aids reducing greenhouse gas emissions through sequestration but also promotes environmental sustainability by yielding nutrient‐rich by‐products for agriculture. As versatile energy‐efficient solution, is pivotal innovation waste‐to‐energy conversion, addressing imperative management. Other supplementary benefits are presented; they include employability, reduction nation's reliance imported energy, better control, therefore considering all pillars sustainability. Future research should focus optimizing efficiency exploring broader applicability feedstocks, enhancing its role global pursuit solutions.

The rapid evolution of Li-ion battery technologies and manufacturing processes demands a continual update environmental impact data. general objective this paper is to publish up-to-date primary data on manufacturing, which great importance the scientific community decision-makers. impacts have been calculated estimated based publicly available disclosed under Hungarian government regulations official decrees. gate-to-gate energy use, greenhouse gas (GHG) emissions, water consumption, N-methyl-2-pyrrolidone (NMP) consumption are for three factories in Hungary, with total annual capacity approximately 100 GWh. use around 30–35 kWh per associated GHG emissions 10 kgCO2eq cell production. varies considerably among factories, one plant using 28 L other two 56 67 kWh. specific NMP was resulting close values 0.51–0.56 kg As new approach, we distinguish between global local related main component latter carbon dioxide from combustion natural gas, but transport also source emissions. Our estimations include not only consumptions required directly technology, those social purposes (e.g., heating offices), giving more complete picture factory’s impact. We believe that crucial ensuring transparency holds significant value both

La Doping LiNiO₂ Cathode to Immobilize the Lattice Oxygen for Highly Stable Lithium-Ion Batteries

Nano Letters, Journal Year: 2025, Volume and Issue: unknown

Published: March 25, 2025

LiNiO2 (LNO) with a high theoretical capacity and entirely free of cobalt has aroused much attention as promising cathode material for lithium-ion batteries (LIBs). The rapid decay, however, obstructs its commercialization. We first propose strategy La lattice-doping in the LNO (La-LNO) high-stability LIBs. Density-functional theory calculations suggest that dopant occupies Ni-sites to stabilize lattice oxygen due strengthening transition metal-oxygen bonds mitigation charge compensation. lattice-doped materials were fabricated successfully had specific 159.6 mAh g-1 after 100 cycles at 1 C retention 94.2% voltage 99.9%. Atomic characterization reveals La-LNO effectively inhibits release phase transformation during cycling process. Our provides leading guidance designing practical high-performance advanced
