Abstract

Direct use of geothermal energy is the oldest and most versatile form of utilizing geothermal energy. In the last decade, this utilization has significantly increased, especially with the installation of geothermal (ground-source) heat pumps. Many current and inactive mine land sites across the U.S. could be redeveloped with clean energy technologies such as direct use geothermal, which would revitalize former mining communities, help with reducing greenhouse gas emissions, and accelerate the transition to a clean energy economy. We present a multicriteria screening framework to evaluate various aspects of direct-use geothermal projects on mine lands. The criteria are divided into three categories: (1) technical potential, (2) demand and benefits, and (3) regulatory and permitting. We demonstrate the framework using publicly available data on a national scale (continental U.S.). Then, using an example of abandoned coal mines in Illinois and focusing on resource potential, we illustrate how this evaluation can be applied at the state or more local scales when a region’s characteristics drive spatial variability estimates. The strength of this approach is the ability to combine seemingly disparate parameters and inputs from numerous sources. The framework is very flexible—additional criteria can be easily incorporated and weights modified if input data support them. Vice versa, the framework can also help identify additional data needed for evaluating those criteria. The multicriteria screening evaluation methodology provides a framework for identifying potential candidates for detailed site evaluation and characterization.

矿区地热资源直接供暖多标准筛选评估
直接利用地热能是利用地热能最古老、最广泛的形式。在过去的十年中,这种利用方式显著增加,特别是随着地热(地源)热泵的安装。全美许多现有和闲置的矿区都可以利用直接利用地热等清洁能源技术进行再开发,这将振兴以前的采矿社区,有助于减少温室气体排放,并加快向清洁能源经济的转型。我们提出了一个多标准筛选框架,用于评估矿区直接利用地热项目的各个方面。标准分为三类:(1)技术潜力;(2)需求和效益;(3)监管和许可。我们使用全国范围(美国大陆)的公开数据来演示该框架。然后,我们以伊利诺伊州的废弃煤矿为例,以资源潜力为重点,说明当一个地区的特征驱动空间变异性估计时,如何在州或更多地方尺度上应用这种评估方法。这种方法的优势在于能够将看似不同的参数和来自多个来源的输入相结合。该框架非常灵活--如果输入数据支持,可以很容易地纳入额外的标准并修改权重。反之亦然,该框架还能帮助确定评估这些标准所需的额外数据。多标准筛选评估方法提供了一个框架,可用于确定潜在的候选地点,以便进行详细的地点评估和特征描述。

期刊介绍: Geothermal Energy is a peer-reviewed fully open access journal published under the SpringerOpen brand. It focuses on fundamental and applied research needed to deploy technologies for developing and integrating geothermal energy as one key element in the future energy portfolio. Contributions include geological, geophysical, and geochemical studies; exploration of geothermal fields; reservoir characterization and modeling; development of productivity-enhancing methods; and approaches to achieve robust and economic plant operation. Geothermal Energy serves to examine the interaction of individual system components while taking the whole process into account, from the development of the reservoir to the economic provision of geothermal energy.
