Biomass resources maps

This data set contains spatial raster files, plotting biomass resources for the Australian states. Data type: .tif files Spatial resolution: 5x5 km Projection: "+proj=utm +zone=56 +south +datum=WGS84 +units=m +no_defs +ellps=WGS84 +towgs84=0,0,0" Biomass types: (a) Bagasse (bagasse), as remaining feedstock following the extraction of sugar from sugarcane (b) Forestry (native and plantation forestry) resides, summarizing woody biomass sources from forestry (harvest residues) or timber product residues or by-products from sawmills (offcuts, sawdust), as well as recycled wood from municipal waste, commercial waste (e.g. pallets) and residues from construction, demolition sources and from native and plantation forests (c) Stubble residues (cropping), describing crop straw from standing stubble (of wheat, oats, barley, triticale, sorghum, canola, lupins, oil seeds and legumes). These low-moisture feedstocks (moisture content ≤ 50%) can for example be used for steam generation from direct combustion and thermal conversion into electricity in Rankine cycle power plants. Due to the limited research scope, this study does not consider high-moisture feedstocks (e.g. animal waste and livestock residues), for anaerobic digestion (AD). Australian states: New South Wales (NSW), Queensland (QLD), Western Australia (WA), Northern Territory (NT), Victoria (VIC), Tasmania (TAS) and South Australia (SA). The Australian Capital Territory (ACT) is, due to its small size, combined with New South Wales (NSW). To our knowledge, the new biomass site database is the most comprehensive compilation of prospective biomass sites, based on up-to-date biomass resources maps at high spatial resolution. By considering the real-world spatial constraints, this new data set allows for a more realistic description of biomass usage in high-renewable energy supply models to better understand the potential of bioenergy in Australia.

本数据集包含空间栅格文件（spatial raster files），用于绘制澳大利亚各州的生物质资源分布情况。数据格式：.tif文件。空间分辨率：5×5千米。投影参数："+proj=utm +zone=56 +south +datum=WGS84 +units=m +no_defs +ellps=WGS84 +towgs84=0,0,0"。生物质类型如下：（a）蔗渣（Bagasse）：指从甘蔗中提取蔗糖后剩余的原料；（b）林业生物质（原生林与人工林）：涵盖林业采伐剩余物、木材制品残余物、锯木厂副产物（边角料、锯屑），以及来自城市生活垃圾、商业废弃物（如托盘）的回收木材，另有建筑拆除残余物，以及原生林与人工林产生的木质生物质资源；（c）秸秆残余物（种植业）：指小麦、燕麦、大麦、小黑麦、高粱、油菜、羽扇豆、油料作物及豆科作物的直立秸秆残余物。这类低水分原料（含水率≤50%）可用于直接燃烧产蒸汽，也可在朗肯循环（Rankine cycle）发电厂中通过热转化方式发电。鉴于研究范围有限，本数据集未考虑用于厌氧消化（Anaerobic Digestion，缩写AD）的高水分原料，例如动物粪便与畜禽养殖残余物。澳大利亚所辖行政区域包括新南威尔士州（New South Wales，缩写NSW）、昆士兰州（Queensland，缩写QLD）、西澳大利亚州（Western Australia，缩写WA）、北领地（Northern Territory，缩写NT）、维多利亚州（Victoria，缩写VIC）、塔斯马尼亚州（Tasmania，缩写TAS）以及南澳大利亚州（South Australia，缩写SA）。由于面积狭小，澳大利亚首都领地（Australian Capital Territory，缩写ACT）被并入新南威尔士州进行统计。据现有认知，本新型生物质点位数据库是基于高空间分辨率最新生物质资源图谱所编制的最为全面的潜在生物质点位合集。通过考量真实世界中的空间约束条件，本数据集能够在高可再生能源供应模型中更真实地描述生物质利用情况，进而助力我们更好地理解澳大利亚生物能源的发展潜力。
