Assessment of liquid biofuel potential from energy crops within the sustainable water–land–energy–carbon nexus

Abstract

With the rapid development of biofuels, doubts about their sustainability have also been raised.

Land and water requirements for the supply of renewable heating and transport energy using anaerobic digestion and water electrolysis. A case study for the UK

“…type of soil, moisture, temperature). By comparison, a spatial distribution of the potential yields of cassava and sweet sorghum was obtained for five provinces in China, obtaining biomass yields in the wide range 0.07-60 t/ha.year, with an average value of approximately 30 t/ha.year [13]. Since the scenarios with miscanthus require much larger areas than the other scenarios, in the rest of the sensitivity analysis (Figures 2b)-f)) the scenarios with miscanthus are excluded, in order to focus our analysis on the more interesting scenarios based on WE.…”

“…Various constraints have so far limited a wider uptake of renewable energy for transport and household heating. An important factor is the land requirement of renewable energy technologies [9], which has been considered in several studies [10][11][12][13]. Land is required to generate renewable electricity, to be used directly in electric vehicles or indirectly for hydrogen generation via WE and for the growth of energy crops to be used in AD.…”

Biodiesel Synthesis From Cucumis melo Var. agrestis Seed Oil: Toward Non-food Biomass Biorefineries

“…Biofuels such as biogas, bioalcohols, bioether, and biodiesel have attracted great attention as promising stand-ins for traditional fossil fuels because of human health hazards and climate change over the past 25 years (Ahmad et al, 2011b;Callegari et al, 2020). Among these options, biodiesel has emerged as a promising replacement for petrodiesel because its consumption is linked with nitrogen oxide emission, which grasps greenhouse gases in extra amounts (Wang et al, 2021;Yusuff et al, 2021). Pre-combustion and post-combustion techniques can be altered to reduce nitrogen oxides (Ahmad et al, 2011c).…”
