Sustainable Alloys for Energy Technologies

About


The transition to resilient energy systems requires solutions for material challenges that integrate long-term durability, resource efficiency, innovative and sustainable processing routes, and compatibility with extreme operating environments. Metals and alloys are indispensable for enabling key thermal and chemical energy technologies, yet they face persistent challenges, including the need for sustainable alloy and process concepts that reduce energy consumption and reliance on critical raw materials; exposure to complex and harsh operating conditions involving mechanical loads, extreme temperatures, reactive atmospheres, and corrosive media; and vulnerability to hydrogen-induced degradation. Meeting these challenges is essential for advancing technologies such as concentrated solar power (CSP), gas turbines (GTs), solid oxide fuel cells (SOFCs), and hydrogen-based systems for transport, storage, and conversion.

In this context, we focus on the development, processing, and characterization of sustainable alloys tailored to the demands of thermal and chemical energy technologies. By combining thermodynamic-based alloy and microstructure design, innovative manufacturing technologies, advanced high-throughput experimental techniques, and data-driven approaches, we design sustainable alloys that are resilient under extreme conditions, resource-efficient, and compatible with hydrogen environments.

Our research connects accelerated material discovery, innovative processing, and evaluation of material behavior under representative operating conditions, thereby creating unique pathways for advancing the development of sustainable alloys.
