Techno-Economic Analysis and Market Potential of Geological Thermal Energy Storage (GeoTES) Charged With Solar Thermal and Heat Pumps into Depleted Oil/Gas Reservoirs and Shallow Reservoirs: A Technology Overview
枯竭的油气储层不仅代表了地下资源和钻井投资的浪费，同时也对地球环境构成潜在风险。为了解决这个问题，地热能存储（GeoTES）被提议用于将枯竭油气储层转化为长期季节性能源存储场所。GeoTES可以与其他技术结合使用，例如1）集中式太阳能电站（CSP）的集热器和2）利用多余可再生能源的热泵，以实现商业化部署。本文提供了两种GeoTES技术的技术概述，包括系统概述、技术经济模型和案例研究。研究表明，这两种GeoTES技术在经济学和适用性方面具有巨大潜力，能够在整个美国范围内得到广泛应用。
Abstract
Depleted oil/gas reservoirs represent a waste of underground resources and investments of drilling, and also a potential risk to the earth’s environment. Geologic thermal energy storage (GeoTES) is proposed as a solution to convert depleted oil/gas reservoirs into long-term seasonal energy storage. GeoTES can be hybridized with other techniques for viable commercial deployment, such as 1) concentrating solar power (CSP) collectors and 2) heat pumps with excess renewable energy. Here, a technology overview is given on the two GeoTES technologies, which includes system overview, techno-economic models, and case study. Both GeoTES technologies show great potential in the economics of individual project deployment and applicability across the US
