Limerick Wave Ltd

Limerick Wave Ltd is a specialist wave‑energy research company based in Limerick, Ireland. Founded a decade ago by tool‑design veteran Patrick Kelly and bolstered by the academic expertise of Dr Patrick Walsh, the firm concentrates on creating innovative Power Take‑Off (PTO) systems that convert the mechanical motion of ocean waves into usable electricity.

The flagship offering is the patented Aontreo PTO technology, which uniquely translates the bi‑directional oscillation of a flotation device into a single‑direction rotation, driving a generator that is protected from the harsh marine environment. This system can be integrated with any Wave Energy Converter (WEC) that captures the two‑way motion of the sea, making it a versatile solution for developers seeking efficient, tunable wave‑energy conversion. Limerick Wave’s business model centres on licensing the technology to partners across the national, European and global markets, positioning the company as a key enabler of sustainable offshore power generation.
