Special Issue Information

Dear Colleagues,

Biomass, a versatile and readily available resource, stands at the forefront of energy innovation, offering a pathway to climate-friendly energy alternatives. This Special Issue aims to showcase cutting-edge research and insights on biomass energy, exploring both its potential and challenges in contributing to a greener and more resilient energy landscape.

We invite submissions that advance understanding of the following topics:

  • Advances in biomass conversion technologies;
  • Bioenergy and carbon sequestration (carbon capture and storage (CCS));
  • Sustainable biomass production and sourcing;
  • Biomass and rural development;
  • Environmental and social impacts of biomass energy;
  • Integration of biomass with other renewable sources;
  • Economic viability and policy implications;
  • Technological challenges and future prospects.

This Special Issue welcomes original research articles, comprehensive reviews, and thought-provoking perspectives that illuminate the role of biomass in shaping a sustainable energy future.

We look forward to receiving contributions from researchers, practitioners, and policy experts that offer innovative solutions and critical perspectives on the future of biomass energy.

Organic wastes from households, private gardens, the maintenance of urban greenery, and active nature conservation measures are often difficult to manage. This lignocellulosic biomass may be suitable for anaerobic digestion (AD). However, the mono-digestion of plant material, such as waste from active conservation measures for wetlands, results in a low methane (CH4) yield. The aim of this study was to assess the feasibility of using common reed silage for co-digestion with plant-based biowaste from households. The specific methane yield (SMY) was determined in biochemical methane potential (BMP) tests performed on biowaste, reed silage, and combinations of reed silage with 10%, 30%, 50%, 70%, and 90% of biowaste on a fresh weight basis. The lowest SMY was observed for the mono-digestion of reed silage (160.40 ± 4.09 NL kgVS−1), while biowaste had the highest CH4 yield (284.03 ± 7.03 NL kgVS−1). The subsequent addition of biowaste enhanced CH4 production from 158.57 ± 7.88 NL kgVS−1 (10% of biowaste) to 233.28 ± 11.91 NL kgVS−1 (90% of biowaste). A key advantage of biogas production is its role in reducing CO2 emissions into the atmosphere, which result from the use of conventional fuels for energy generation. The avoided CO2 emissions generated in electricity and heat production range between 378.62 kgCO2 tTS−1 and 676.36 kgCO2 tTS−1 depending on the reed silage-to-biowaste ratio used for biogas production. This study reveals that reed silage is not an optimal feedstock for biogas production, and its share in co-digestion with biowaste should not exceed 10% of the total input to the biogas plant.

This paper explores the integration and advancements of artificial neural networks (ANNs) in modeling diesel engine performance, particularly focusing on biodiesel-fueled engines. ANNs have emerged as a vital tool in predicting and optimizing engine parameters, contributing to the enhancement of fuel efficiency and a reduction in emissions. The novelty of this review lies in its critical analysis of the existing literature on ANN applications in biodiesel engines, identifying gaps in optimization and emission control. While ANNs have shown promise in predicting engine parameters, fuel efficiency, and emission reduction, this paper highlights their limitations and areas for improvement, especially in the context of biodiesel-fueled engines. The integration of ANNs with big data and sophisticated algorithms paves the way for more accurate and reliable engine modeling, essential for advancing sustainable and eco-friendly automotive technologies. This research underscores the growing importance of ANNs in optimizing biodiesel-fueled diesel engines, aligning with global efforts towards cleaner and more sustainable energy solutions.
