Carnegie Clean Energy (ASX:CCE) has released details of its ACHIEVE programme, outlining six technical and commercial objectives for its 80 kW, half-physical-scale CETO wave energy demonstrator, which is designed to validate next-generation technology ahead of potential commercial-scale deployment.

Key Points

  • The ACHIEVE demonstrator is an 80 kW, half-physical-scale CETO unit described as a first-of-a-kind offshore demonstration.
  • Six programme objectives cover commercial viability, energy capture, control systems, survivability, operations and maintenance, and technology development.
  • Future commercial-scale deployments are modelled with an expected capacity factor range of 30–50%, with a forecast spatial density of 30 MW/km².
  • Carnegie is developing plans for a 6 MW project at BIMEP in Spain and has identified additional opportunities with defence and data centres.
  • Carnegie secured top ranking in the EuropeWave programme, which provided cornerstone funding for ACHIEVE.

ACHIEVE Programme Objectives and CETO Demonstrator Design

The ACHIEVE programme is structured around six objectives: commercial objectives, energy capture and power conversion, advanced control system evaluation, survivability and reliability, operations and maintenance, and technology development. The 80 kW CETO unit operates fully submerged beneath the surface, a design feature the company said is intended to enhance safety during storms and avoid visual impact from shore. The filing states the modular architecture is aimed at easing fabrication, transport, assembly and integration using existing industrial supply chains and port infrastructure, with the potential for scalable manufacturing and simpler installation using smaller vessels.

Energy Capture, Control Systems and Survivability Testing

According to the filing, the ACHIEVE demonstrator will test power production against pre-deployment models, targeting a 30–50% capacity factor range for future commercial-scale deployments at selected sites across Spain, Portugal, France, the UK, Ireland, Australia and the United States. A forecast spatial density of 30 MW/km² is cited for commercial CETO, compared to a typical 6 MW/km² for offshore wind. The control system was developed in collaboration with HPE and incorporates AI-based reinforcement learning and machine learning. Survivability strategies include active position adjustment within the water column during extreme sea conditions, with the system designed to continue generating electricity while maintaining structural integrity.

Commercial Pathway, EuropeWave Funding and Market Context

The filing states that design advances developed during Carnegie's Digital Development Pathway underpinned its top-ranked position in the EuropeWave programme and secured cornerstone funding for ACHIEVE. The programme is generating data to support cost-of-energy assessments, with initial economic modelling independently reviewed and verified as part of the EuropeWave funding process. Carnegie disclosed that it is developing plans for a 6 MW project at BIMEP in Spain, and that its business model is designed to demonstrate revenues three to four years prior to commercial project commissioning. The EU has set targets of 1 GW of installed ocean energy capacity by 2030 and 40 GW by 2050, which the filing identifies as the primary market context for Carnegie's commercial strategy.
