Diverse biomass sources from the Canary Islands (vineyard, tomato plant residues, Canary pine needles and ) were assessed due to their local abundance, availability, and low supply cost. Based on their physico-chemical properties, various thermochemical processes were conducted to assess their thermal degradation behaviour, using simultaneous thermal analysis, and their potential for energy production. The results indicate that while tomato plant biomass is unsuitable for thermochemical processes because of its elevated ash content and limited volatile matter, the other biomass sources show promising potential for pyrolysis and gasification, characterized by high fixed carbon content and reactivity. The yearly production of residual biomass in the Canary Islands was quantified at 87,253 tonnes. This biomass could generate an estimated 88.5 GWh of electricity annually. Considering that electricity consumption in the Canary Islands reached 8750 GWh in 2023, biomass-derived electricity could contribute approximately 1.0 % to the archipelago's energy needs. These findings highlight the significant role of local biomass resources in advancing renewable energy goals and reduce dependence on non-renewable sources, promoting a greener energy landscape for the Canary Islands.

加强加那利群岛的可持续能源生产：通过热化学过程实现当地生物质资源的增值


由于当地丰富、可获得性和供应成本低，对加那利群岛的多种生物质来源（葡萄园、番茄植物残留物、加那利松针等）进行了评估。根据它们的物理化学性质，使用同步热分析进行各种热化学过程来评估它们的热降解行为及其能源生产潜力。结果表明，虽然番茄植物生物质因其灰分含量较高和挥发性物质有限而不适合热化学过程，但其他生物质来源显示出热解和气化的广阔潜力，其特点是固定碳含量高和反应活性高。加那利群岛的剩余生物质年产量为 87,253 吨。这种生物质每年估计可产生 88.5 GWh 的电力。考虑到2023年加那利群岛的电力消耗达到8750吉瓦时，生物质发电可为该群岛的能源需求贡献约1.0%。这些发现凸显了当地生物质资源在推进可再生能源目标、减少对不可再生能源的依赖、促进加那利群岛绿色能源景观方面的重要作用。
