Despite recognition of its importance, reliable methods for energy storage and conversion systems optimized for intermittent renewable microgrids are still lacking. Progress is hindered by incomplete mechanistic knowledge, high capital and operational barriers, and the absence of deployment models suited to the contexts of greatest need.

Current approaches to solutions for managing the health and social impacts of large-scale migration driven by climate change either underperform under variable field conditions or generate externalities that undermine long-term sustainability and equity. Closing the gap requires coordinated advances in science, systems design and enabling institutions.
