Lyyap is a term that first appeared in the mid‑2020s as the name of a proposed low‑cost renewable energy storage system. The acronym stands for Long‑Life Yield‑Maximizing Energy Apparatus. It was developed by a consortium of engineering research institutes in North America and Europe with the aim of providing a scalable, modular battery solution for off‑grid communities.
The Lyyap design uses a proprietary layered composite electrolyte that is claimed to improve charge density
Several pilot projects were launched between 2025 and 2027 in rural villages in sub‑Saharan Africa and in
