Repository of problems worth solving
World Solve is a public institutional repository for identifying real unresolved problems across science, society, health, governance, economics, and local systems. Each entry is intended to be citable, inspectable, and actionable.
Publicly citable
Every problem has a stable citation code for reference and discussion.
Filtered by relevance
Search by category, geography, status, and keywords.
Builder-oriented
Use the repository to find startup ideas, policy leads, and research agendas.

Storing renewable energy at the scale needed to fully support national power grids still requires battery technology that remains too expensive for widespread deployment. Closing this cost gap remains one of the biggest barriers to a fully renewable grid.

Hospitals, power plants, and water systems increasingly run on connected computer systems that can be targeted remotely. A serious attack on any of these could cause harm far beyond the digital world.

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.
