The following reports have been produced discussing the progress, potential and challenges being faced in the marine renewables industry:
The potential for wave and tidal stream to make a material contribution to the UK’s energy mix is well recognised, and is reflected in the level of UK activity. As the industry moves from full-scale prototype stage to first arrays, the key challenge facing the marine energy industry is lowering the cost of energy generation. The Marine Energy Accelerator (MEA) has supported technology innovation over the past four years, and has set out clear pathways for future cost of energy reduction: with sufficient focus on innovation we believe the costs of energy from marine generators can be competitive with other renewable technologies by the mid 2020s.

To help meet the EU’s goal of climate neutrality by 2050, the European Commission presents the EU Strategy on Offshore Renewable Energy. The Strategy proposes to increase Europe’s offshore wind capacity from its current level of 12 GW to at least 60 GW by 2030 and to 300 GW by 2050. The Commission aims to complement this with 40 GW of ocean energy and other emerging technologies such as floating wind and solar by 2050.

This report highlights the key areas where space-based applications and technologies can play an important role to overcome challenges such as effective and efficient location scouting, bankability estimations, environmental policy decision making, monitoring and maintence and system planning and transmission activities.
Energy Technologies Institute (ETI)
Technology roadmaps are tools that provide a framework for stimulating innovation in specific technology areas in order to achieve a long term vision, target or goal. The aim of this roadmap is to facilitate the establishment of a commercially viable marine energy sector in the UK, supported by an extensive supply chain, thereby building the skills and capacity necessary to enable the sector to make a material and cost-effective contribution to the delivery of the UK’s energy and climate change goals.
ETIP Ocean undertook extensive economic modelling work to establish the economic and jobs impacts of ocean energy deployments under two contrasting scenarios: Europe leading the global market, or Europe following the global market. It reports that by taking the lead in the global ocean energy market, Europe will benefit from economic activity worth €140bn by 2050
This Strategic Research and Innovation Agenda (SRIA) for ocean energy outlines the priority research, development and innovation challenges that must be focused upon in the years ahead. The SRIA gives guidance to all funders of innovation – industry, EU, national and regional – by presenting concrete research and innovation actions that will allow ocean energy to meet its SET Plan targets.
The report analyses the challenges faced by the sector on the route to industrial roll-out and proposes four actions to overcome them. Dedicated revenue support at national level is essential to attract investment for ocean energy farms. Alongside revenue support, a model for ‘blended’ public finance will allow the next round of ocean energy projects to reach financial close. The report highlights ocean energy’s recent successes, with record volumes of power being supplied to the grid by tidal stream technology, and several promising scale and full-sized wave devices going into the water. It reiterates ocean energy’s potential of providing 10% of Europe’s current electricity consumption by 2050.
IRENA (International Renewable Energy Agency)
This outlook from the International Renewable Energy Agency (IRENA) examines the status and prospects of ocean energy technologies. It examines the operating principles, current installed capacity and projected project pipeline, along with markets and theoretical energy potential for each ocean energy type. The report also identifies challenges and offers recommendations to accelerate the deployment and commercialisation of each technology.

Wales has experienced an unprecedented surge in spending and investment, with a staggering £103.4 million recorded. The primary catalysts for this are infrastructure expansions, which are paving the way for upcoming deployments.
National Hydropower Association (NHA)
Report set industry deployment targets for ocean energy and calls on the U.S. Federal Government to accelerate commercialization of marine energy technologies (wave, tidal, ocean current, ocean thermal, and riverine) by increasing financial support for research and development, reducing market barriers and creating financial incentives for technology deployment.
Ocean Energy Europe
Public financing of ocean energy must be designed to create a ‘pull’ for private investment in a global market that could reach 350 Gigawatts by 2050, says a new report co-authored by the International Renewable Energy Agency (IRENA) and Ocean Energy Europe (OEE). By making sure funding instruments are adapted to meet the sector’s needs, governments around the world can leverage private financing, speed up technological development and drive down costs.
The annual key trends and statistics publication from Ocean Energy Europe gathers data from the sector to present the latest state-of-play in Europe and worldwide.
The twin geopolitical and energy crises have thrown into sharp relief the high costs of Europe’s continued fossil gas dependency. Rising prices and supply threats clearly highlight the necessity to quickly decarbonise and diversify our energy mix. Ocean energy is now more relevant than ever.
This report identifies the key environmental research needs and consenting challenges that require action at an EU and national level, to facilitate the roll out of ocean energy. It analyses the latest environmental research and the current EU and national level policies and regulations regarding ocean energy. It makes environmental research, policy and regulatory recommendations and proposes a concrete Strategic Action Plan.
Ocean Energy Europe’s vision for 2030 sets out the sector’s plans for ambitious deployments, dramatic cost reductions and exciting industrial growth over the coming decade. The document outlines high and low growth scenarios, maps the extensive supply chain and make recommendations for policy actions.

Ocean Energy Forum
This Strategic Roadmap was commissioned by the European Commission Directorate-General in collaboration with the Ocean Energy Forum. The Ocean Energy Forum has been set up to bring together stakeholders to develop a shared understanding of the problems faced by the Ocean Energy sector and to collectively devise workable solutions. The Forum is supported by a Secretariat whose main role is to help ensure the production and timely delivery of the Strategic Roadmap. The Secretariat previously publicised the Draft Ocean Energy Forum Strategic Roadmap dated 12 October 2015. The period October 2015 through to 2016 focused on the analysis of the Roadmap evidence-base and progress on implementation of the Roadmap Key Recommendations with the final update of the Roadmap published in November 2016.
Ocean Energy Systems (OES)
This comprehensive report provides an overview of national policies, research, and technology demonstration on ocean energy in member countries across Australia, Asia, Europe, and the Americas. Additionally, the report highlights the achievements and progress of IEA-OES collaborative projects.
This report reflects the most current and pertinent published information about interactions of marine renewable energy devices and associated infrastructure with the animals and habitats that make up the marine environment. It has been developed and reviewed by over 60 international experts and scientists from around the world as part of an ongoing effort supported by the OES collaboration that operates within the International Technology Cooperation Framework of the International Energy Agency (IEA).
Many ocean-based applications and markets are located far from the coast, facing important offshore challenges, such the need for clean power. From the experts interviewed by OES there is a consensus that ocean energy can meet these anticipated needs and unlock the growth potential of the blue economy.
OES report shows that islands and other off-grid markets may present opportunities for ocean energy developers to deploy their technologies while providing sustainable energy to local communities
