Perth-based wave energy innovator WaveX has joined forces with global engineering consultancy Arup to accelerate the development of its D-Spar wave energy converter through two Memorandums of Understanding (MOUs).
The collaboration aims to refine the design of the floating generator, which harnesses ocean wave motion to produce renewable electricity, and integrate it with Arup’s proprietary shared mooring system for large-scale deployment.
The D-Spar system, a self-reacting wave energy conversion technology, distinguishes itself with no underwater moving parts — a design choice that enhances durability and reduces maintenance costs.
By leveraging vertical wave motion, the device generates electricity to complement intermittent wind and solar power, potentially reducing reliance on grid-scale batteries.
Initial collaboration efforts will focus on optimising electrical systems and power transfer units in partnership with Trident Energy, while a parallel study will evaluate Arup’s shared mooring system for a planned project off Western Australia’s southern coast.
The partnership aligns with WaveX’s goal to deploy a large-scale prototype in WA waters by late 2025, supported by the University of Western Australia’s wave energy facility.
The project seeks to validate the D-Spar’s commercial viability and contribute to the Ocean Energy Systems roadmap target of 300GW of global wave and tidal energy capacity by 2050.
Arup’s mooring technology, designed for scalability across shallow and deep waters, could enhance energy production density and reduce costs for future offshore arrays.
Simon Renwick, CEO of WaveX, emphasised the strategic value of the partnership: “Arup’s expertise in electrical and mooring design will strengthen the D-Spar as a global solution for wave energy projects, pushing innovation boundaries in a sector with vast untapped potential.”
Damon Sunderland, Arup’s Australasia Offshore Wind Lead, highlighted the mooring system’s advantages, stating: “Our approach maximises survivability and profitability for commercial-scale projects, offering a pathway to cost-effective renewable energy generation.”
The collaboration underscores growing momentum in marine renewables, targeting coastal communities worldwide where over three billion people reside near ocean energy resources.
If successful, the D-Spar could mark a turning point in diversifying the renewable energy mix and advancing global decarbonisation goals.
