RT Journal Article T1 Environmental Assessment tool in DTOcean+: reducing local and global environmental impacts for ocean energy projects A1 Araignous, Emma A1 Kervella, Youen A1 Michelet, Nicolas A1 Luxcey, Neil A1 Nava, Vincenzo A1 Duarte, Rui A1 Isorna, Rocio A1 Safi, Georges AB — Designing reliable ocean energy devices with reduced costs is crucial for the sector’s development. This development of renewable energies should also be implemented in a sustainable manner and not cause additional environmental stress and related damage. In order for the ocean energy sector to consider environmental impacts at the earliest stage of concept creation, the Environmental Assessment (EA) module was developed and included in an integrative suite of design and assessment tools (namely DTOceanPlus) to support technology innovation processes. Several complementary features were developed in the EA module which provides insight into impacts at different levels. At local scale, environmental impacts are assessed in relation to the different design choices that cover various potential pressures induced by the ocean energy array. Moreover, surveys and mitigation measures are provided regarding endangered species potentially present. At global scale, a life cycle assessment is conducted to evaluate the carbon footprint of a project in terms of its contribution to global warming and the cumulative energy demand. The present paper describes the integration of EA into DTOcean+ and two case studies were used to exemplify the use and relevancy of the EA’s features to evaluate environmental impacts of a wave and a tidal ocean energy projects. Overall the EA module provides insight and support to the ocean energy sector to achieve sustainable development of marine renewable energies.

The goal of the DTO+ project is the acceleration of commercialization within the ocean energy sector (https://gitlab.com/dtoceanplus; it is worth noticing that in the online version, the tool is called Environmental and Social Acceptance “ESA” as it will also include social aspects of ocean energy project in further development). DTO+ was designed to mitigate the technical and financial risks of the technology to achieve the deployment of cost‐competitive wave and tidal arrays. The objective is to underpin a rapid reduction in the Levelized Cost of Energy offered by facilitating improvement of the reliability and survivability performance of ocean energy systems, and analyzing the impact of design on energy yield, operation and maintenance, as well as on the environment, thus making the sector more attractive for private investment. DTO+ aligns innovation and development processes with those used in mature engineering sectors: ‐ Technology concept selection is facilitated by a Structured Innovation tool [25], [26]. ‐ Technology development is enabled by a Stage‐Gate tool [27]. ‐ Technology deployment is supported by a set multidisciplinary design [28]–[34] and assessment tools [35]–[39] that produce metrics used as inputs by the Stage Gate and Structured Innovation tools, as illustrated in Fig.1. Horizon 2020 uses a scale of Technology Readiness Levels (TRL) to evaluate project eligibility [40]. This baseline has been used within the DTO+ project to define the complexity levels of the tool. In this sense, each module can be used at three levels of complexity that reflect the stage of development of the user project and the level of DS TECNALIA Publications RD 30 jul 2024
