| Abstract | Unlocking the full economic value of geothermal energy requires innovation not only in technology but in the broader economic systems that shape investment, risk, and value distribution. This paper explores how banks and financial institutions can serve as catalysts for innovation in geothermal economics by promoting lifecycle-aligned strategies that integrate resource exploration, project development, daily operation, decommissioning management, and community reinvestment. Traditional geothermal economics model tends to focus on initial returns, often neglecting long-term environmental and social costs that undermine project viability. In response, this paper introduces a portfolio of forward-looking economic tools, including credit models linked to sustainable performance, geothermal decommissioning reserve mechanisms, and capital allocation methods based on green operational results, all constructed based on ESG principles and climate resilient investment frameworks. Drawing on case studies from Iceland, Kenya, and Indonesia, this paper demonstrates how such innovations improve economic viability, reduce lifecycle costs, and enhance both stakeholder alignment and societal acceptance. The paper further outlines opportunities for banks to collaborate with governments, insurers, and ESG data providers to jointly build adaptive economic models that reflect evolving environmental and policy risks. By aligning banking strategies with the full economic lifecycle of geothermal projects, financial institutions can not only manage capital risk more effectively but also contribute to the formation of a resilient, investable, and socially inclusive geothermal economy, injecting systemic impetus into a just and sustainable energy transition. |
