Towards Green and Energy Transitions: Techno-Economic Analysis, Optimization, and Innovation Pathways for Sustainability

Dear Colleagues,

The urgent challenges of climate change, resource scarcity, and the global energy transition require a fundamental transformation of energy and production systems toward sustainability, resilience, and efficiency. Achieving ambitious decarbonization targets demands integrated approaches that combine technological innovation, economic viability, environmental performance, and effective policy frameworks.

Techno-economic analysis (TEA) and optimization methodologies play a central role in supporting decision making for the design, evaluation, and deployment of advanced energy systems. These approaches are increasingly enhanced by digitalization, data-driven methods, and artificial intelligence, enabling more comprehensive assessments of complex and interconnected systems.

At the same time, circular economy principles are reshaping the way energy and resources are produced, utilized, and managed. The integration of circularity with energy systems, along with the advancement of green technologies, innovation, and sustainable business models, is essential for accelerating the transition toward low-carbon and resource-efficient solutions across sectors, including energy, industry, and maritime applications.

This Topic aims to bring together interdisciplinary contributions on techno-economic analysis and optimization, addressing the interconnections between energy systems, resource management, and innovation pathways for a sustainable future.
