Design Intelligence Fostering Formidable Energy Reduction and Enabling Novel Totally Impactful Advanced Technology Enhancements

In the 250 years since the dawn of the Industrial Revolution, the pace of technology-driven economic growth has dwarfed that achieved in prior centuries. The emerging artificial intelligence revolution has similar transformational potential, which we seek to leverage to help resolve the energy and environmental challenges that are tied to the modern industrial age.Artificial intelligence (A.I.) makes it possible for machines to learn from experience, adjust to new inputs and perform like humans. Machine learning is a core part of A.I., and it is the study of computer algorithms that improve automatically through experience. Incorporating machine learning into the energy technology and/or product design processes is anticipated to facilitate a rapid transition to lower-carbon-footprint energy sources and systems.

Lawrence Berkeley National Laboratory

Deep Learning and Natural Language Processing for Accelerated Inverse Design of Optical Materials

Over the past 50 years, progress in optical metamaterial device design has led to the manipulation of light over a wide range of wavelengths spanning the ultraviolet to the far infrared, resulting in technological advancements such as selective radiative absorbers for solar energy and daytime passive cooling using deep space. Further advances in optical metamaterial devices could enable increased energy efficiency, reduced national primary energy consumption, inexpensive long duration energy storage, and next generation solid-state heat engines. Lawrence Berkley National Laboratory (LBNL) will develop an optical metamaterial design tool to increase energy efficiency and reduce national primary energy consumption. Besides creating high-quality datasets, LBNL will train physics-informed generative adversarial networks that automatically suggest candidate structures to produce desired optical properties within the constraints of cost of materials and manufacturing. Currently, finding an optimal design can take years and is based mostly on intuition and iteration. The team's machine learning tool will be 10,000 to 100,000 times faster than existing technology.

Machine Learning Assisted Models for Understanding and Optimizing Boiling Heat Transfer on Scalable Random Surfaces

The Massachusetts Institute of Technology (MIT) will develop a machine learning (ML) approach to optimize surfaces for boiling heat transfer and improve energy efficiency for applications ranging from nuclear power plants to industrial process steam generation. Predicting and enhancing boiling heat transfer presently relies on empirical correlations and experimental observations. MIT's technology will use supervised ML models to identify important features and designs that contribute to heat transfer enhancement autonomously. If successful, MIT's designs will lead to more readily adopted scalable surfaces in energy applications, enhancing performance and shortening deployment timetables.

National Renewable Energy Laboratory

End-to-End Optimization for Battery Materials and Molecules by Combining Graph Neural Networks and Reinforcement Learning

The National Renewable Energy Laboratory (NREL) will develop a machine learning-enhanced approach to the design of new battery materials. Currently, such materials are designed in part via numerous expensive high-fidelity computational simulations that predict the performance of a given composition. However, at present, humans must sift through the vast amounts of data generated and manually identify new compositions. To accelerate this process, NREL plans to develop a machine learning enhanced prediction tool that uses existing simulation data to predict the performance of new material compositions at high fidelity but lower cost. NREL plans to combine this tool with reinforcement learning techniques to automate the identification of new candidate compositions. It is expected that these design tools will enable the identification of new battery materials faster and thereby accelerate the rate at which battery performance is improving.

To overcome challenges with the use of traditional DNNs in this application, NREL will develop innovative techniques to sparsify the neural network using active subspaces that will ensure that the model is invertible and can quickly zoom in on relevant designs at minimal cost. The models will be trained using data from computational fluid dynamics simulations, running on NREL's supercomputers, which in turn use machine learning assisted turbulence models to predict flow separation and stall observed in wind turbine flows.
