Country Reports

 

In 2018, WavEC, IST, INEGI, University of Algarve and other Portuguese Universities, public and private entities were active partners in national or international research efforts on ocean energy. The granting support by the Blue Fund (Fundo Azul), a new national funding scheme launched in 2017, aimed at developing the blue economy, has been announced during the year.

There has been continuous progress with the oscillating water column and air turbines, following decades of research in Portugal with this type of wave energy technology and its power take-off. A new turbine prototype has been tested in one of the OWCs of the Mutriku breakwater and further on a floating OWC prototype in the Basque country, at Bimep.

AW-Energy continues active in Portugal, progressing with its project to be installed in Peniche. 

 

 

 

SUPPORTING POLICIES FOR OCEAN ENERGY


NATIONAL STRATEGY
In Portugal, the Ministry of the Sea is responsible for defining policies encouraging the development of new activities in the sea that maximize the use of its resources, generating economic value in a sustainable model. In this sense, the Government programme has a medium- and long-term strategy for the use of the resources of the sea, in which renewable marine energy (wave and offshore wind) is of special relevance. 

Portugal’s Industrial Strategy for Ocean Renewable Energies (EI-ERO) was published in 2017 and is based on two main goals: to stimulate export and value added investment and to assist industry in reducing risks. The corresponding action plan defines that business opportunities in wave energy for Portugal should focus on having the right conditions for attracting R&D investment, in terms of infrastructures and financing. At national level it is estimated that there is a potential between 3 and 4 GW, considering other uses of the sea. The approach to the wave energy market is pursued in three stages: (i) technology development and demonstration by 2022; ii) pre-commercial development between 2023 and 2028; and iii) commercial maturity, with significant activity in 2030.
 
 
MARKET INCENTIVES
In Portugal, electricity from renewable sources from plants registered until 2012 is mainly promoted through a feed-in tariff (FiT). Since 2012 no guaranteed remuneration scheme has been approved for new projects.
 
 
 

PUBLIC FUNDING PROGRAMMES

 

Foundation for Science and Technology (FCT)
The funding of the Portuguese research system is mainly conducted through the Foundation for Science and Technology (FCT), under the authority of the Ministry of Science, Technology and Higher Education. FCT has been funding research on ocean energy via the Ocean Energy European Research Area Network (OCEANERA-NET) programme. This was a network of 15 national and regional funders of research and innovation programmes, from 8 European countries, which have received funding from the European Union under the Horizon 2020 Programme for R&I and ended in February 2018. 

Of the ten projects approved by OCEANERA-NET, FCT funded the participation of Portugal in 8 projects listed below, running until 2018, of which the first 3 were coordinated by Portugal (WavEC, IST and INEGI):
  • KRAKEN: Portugal (WavEC and IST), Spain and Ireland
  • ELASTMOOR: Portugal (IST) and  Sweden
  • SE@PORTS: Portugal (INEGI, UPorto, APDL, FORUM OCEANO), Spain and Belgium
  • CAPTWO: Ireland, Spain and Portugal (Cruz-Atcheson Consulting Engineers and IST)

  • OCEANIC: Sweden, Spain and Portugal (WavEC)
  • RECODE: Spain, Ireland, UK and Portugal (WavEC)
  • TUPPERWAVE: Spain, Ireland and Portugal (WavEC)
Built on the work of this programme, the Ocean Energy ERA-NET Cofund (OCEANERA-NET COFUND) was initiated, operating from 2017 to 2021, also supported by the EU’s Horizon 2020 Programme, involving the participation of 8 national and regional government agencies from 6 European countries. The participating countries/regions are: the Basque Country, Brittany, Ireland, Pays de la Loire (France), Portugal, Scotland, Spain and Sweden. The aim is to coordinate support for research and development in ocean energy, to encourage collaborative projects that tackle some of the key challenges identified for the sector as it progresses towards commercialisation. The national funding commitment for the next call (5 April 2019) is €300.000 with a maximum requested funding for each project with Portuguese participation or coordination of €150.000. 
 
 
Sea Policy General Directorate (DGPM) - BLUE FUND
In 2018, the Sea Policy General Directorate (DGPM) announced the results of the call Blue Fund for the topic Ocean Renewable Energy – “Leading Wave Energy Research” aiming to fund research and development projects on demonstration prototypes for wave energy systems and/or components. The budget allocated for this call reached a total amount of €1.000.000 with a maximum grant per application of € 200.000.
 
Blue Fund is an innovative public financial instrument, managed by the Ministry of the Sea, which started in 2017 focused on the development of the ocean economy, scientific research and protection of the sea environment. It prioritizes the development of sea biotech start-ups, underwater robotics, innovative shipbuilding, ocean energy, aquaculture technology and innovative solutions for ocean protection, safety, monitoring and surveillance.
Six projects have been approved for wave energy demonstration projects and robotic equipment for operations in the sea, led by the following Portuguese institutions: WavEC, IST, inanoEnergy (University of Porto), In2sea, Composite Solutions and Abyssal.
 

National Innovation Agency in Portugal (ANI)
 
Portugal 2020 framework programme is organized into four thematic domains, one of which is dedicated to Sustainability and the Efficient Use of Resources. The global budget for this programme running until 2020 comes from the European Structural Fund aiming to stimulate economic growth and job creation in the country. Within this framework, the Competitiveness and Internationalization Operational Programme (Compete 2020) opens call for all sectors without distinction, not address specific levels of technological readiness. Ocean energy demonstration projects can apply to this programme, managed by the National Innovation Agency in Portugal (ANI).
 
 


RESEARCH & DEVELOPMENT


WavEC Offshore Renewables
WavEC is a private non-profit organization with a strong research and innovation component and a broad spectrum of specialized services in Marine Renewable Energies and Engineering Solutions for the ocean economy, incorporating technological, economic, environmental, social and legislative aspects.  Following is a list of selected R&D projects on ocean energy, running in 2018, in which WavEC has been involved:

In 2018, WETFEET, an European funded project of the H2020 programme led by WavEC, was concluded. This three-year project with a total funding of €3.5millions comprised teams from Austria, France, Italy, Portugal, the Netherlands and the United Kingdom. Using as a starting point the identification of the major constraints that have been delaying wave energy’s progress, WETFEET analysed key pressing issues (technical, economic, financial and environmental) that need to be addressed in order to improve the whole sector. More information at: http://www.wetfeet.eu/
 
In late 2018, three new European funded projects were approved, ETIP Ocean2, an European Technology and Innovation Platform for Ocean Energy, funded by H2020 and BLUEGIFT funded by Interreg Atlantic Area Programme. This last one, managed by EMEC, will give the opportunity to promote open sea testing in Portugal. 
 
 
INSTITUTO SUPERIOR TÉCNICO
Two groups were active on ocean energy at Instituto Superior Técnico (IST):
  • Institute of Mechanical Engineering (IDMEC) with  decades-long history in wave energy conversion studies;
     
  • Centre for Marine Technology and Engineering (CENTEC), whose involvement in ocean energy is more recent.

Following previous years, the activity at IDMEC concentrated on wave energy conversion, especially the development of new types of oscillating water column converters (OWCs) and self-rectifying air turbines. An important area of research at IDMEC is latching control of floating and fixed-structure OWC converters, taking advantage of new types of air turbines fitted with fast valves. 
 
IDMEC/IST was a partner in the WETFEET project coordinated by WaVEC (European H2020 programme) that terminated in May 2018; in 2018 the involvement of IDMEC/IST concerned mainly the development of a multipurpose platform made of OWCs wave energy converters that has been tested at 1:40 scale at Plymouth University. IDMEC/IST is also a partner in the OPERA project (H2020), in which, jointly with the Portuguese company Kymaner, designed a prototype of the biradial self-rectifying air turbine with a new type of fixed guide vanes and a fast valve. The turbine prototype was supplied by Kymaner, and was installed at one of the OWCs of the Mutriku breakwater (Basque Country, Northern Spain), where it was operated under real sea conditions until July 2018. In October 2018, the turbine-generator set was installed on the MARMOK-A-5 spar-buoy OWC of the Spanish company Oceantec/IDOM, and is operating at the BiMEP test site (Bay of Biscay, Northern Spain).
 
Another wave energy converter concept has been under development at IST: the UGEN, a floating device with an interior U-shaped oscillating water column and a self-rectifying air turbine. A 1:24 scale model was tested in 2018 at the wave tank of Plymouth University, UK, within the framework of the European programme MARINET 2.

Ocean energy is a major area in the diversified activity of CENTEC/IST. The activities at CENTEC in ocean energy involved a wide range of topics covering waves, tidal currents and offshore wind. The characterization of the wave energy resource (and to a much lesser extent tidal and offshore wind energies) at various oceanic locations in the world has been one of the dominant topics. The study of ocean energy conversion focused mainly on wave energy converters, with numerical theoretical/modelling and model testing of several types of devices and arrays, and also PTOs (namely hydraulic-circuit PTOs).
 
 
University of Algarve
At University of Algarve there is one active group on tidal current energy, the Marine Offshore Renewable Energy (MORE) team, which has been involved in the following three projects:
  • OpTiCA – Optimisation of Tidal Energy Converter Arrays: a 2-years project funded by H2020 that aims to provide a significant contribution towards the understanding of (a) the effects of Tidal Energy Converters (TECs) interactions with the environment; (b) the capabilities and limitations of common strategies used for the numerical modelling of TECs; and (c) how to mathematically formulate optimisation models to solve the TEC array layout problem considering technical, socio-economic and environmental constraints. This project is led by the Marine Offshore Renewable Energy (MORE) team from the University of Algarve (https://www.msca-optica.eu).
     
  • SCORE - Sustainability of using Ria Formosa Currents On Renewable Energy production: this project funded by the national Foundation for Science and Technology (FCT) started in 2016 and will run for 3 years. The general objective of SCORE is to examine a small scale tidal current turbine Evopod E1 (1:10th scale), from UK-based tidal energy developer Oceanflow Energy, to be deployed in a shallow-water estuarine environment at Ria Formosa, a coastal lagoon in the south of Portugal, looking at both the impacts of the turbine on its environment and the effects of the flow conditions on the turbine (http://w3.ualg.pt/~ampacheco/Score/aboutscore.html)
     
  • MONITOR - Multi-model Investigation of Tidal Energy Converter Reliability: a 3-years project  funded by the European funding programme INTERREG Atlantic Area, that started in 2017, led by Swansea University, whose objectives are to investigate the reliability of tidal energy converters and develop tools to increase it. The roles of the University of Algarve are: 1) to plan and coordinate field work activities from two full scale tidal turbine deployments: Sabella D10 at Passage du Fromveur (France) and Magallanes Renovables’ ATIR platform at EMEC (UK); 2) to collect and process the resulting data; and 3) to publish the findings in a suitable format (https://www.monitoratlantic.eu/).
 
 
INEGI - Institute of Science and Innovation in Mechanical and Industrial Engineering 
INEGI is an Institution at the interface between the University of Porto and the Industry, oriented towards the activities of Research and Development, Innovation and Technology Transfer. INEGI has been involved in nationally and internationally funded and subcontracted projects related to Marine Renewable Energy (mainly offshore wind and wave energy). 
 
Since 2017 INEGI is coordinating the SE@PORTS project, funded by the national Foundation for Science and Technology (FCT) through the funding programme Oceanera-net. In addition, INEGI has been involved in a number of R&D projects related to sea activities mainly funded by the European Commission. Two new projects related to the ocean energy were approved during the year 2018:
  • I.nano.WEC: a 2-year project, which started in May 2018, funded by the national fund “Fundo Azul”, aiming to develop the first marine buoy prototype integrating highly efficient energy harvesting systems based on triboelectric nanogenerators. The coordinator of this project is the InanoEnergy (www.inanoe.com) which is a start-up company created in 2016 to develop, prototype and produce energy harvesting solutions with applications on the internet of things.
     
  • PORTOS: a 3-year project, with start date scheduled to April 2019, funded by the European funding programme INTERREG Atlantic Area, aiming to develop and promote the implementation of renewable energy (RE), especially marine energies at ports in the Atlantic Area, targeting two environmental priorities for ports: reduction of greenhouse gases emissions and air pollution, by providing RE-based solutions to harvest the Renewable Energy potential of the Atlantic coastal areas. Moreover, PORTOS aims to increase the energy efficiency of the ports, establishing a roadmap to a more competitive and sustainable sector, mitigating climate change. PORTOS project will be lead by the University of Porto.

AW Energy’s First-of-a-Kind (FOAK) WaveRoller, which has been fully licensed in 2017, is currently in its final stage before deployment along the coast of Peniche, in Portugal.

 
 

 

35679-pico.jpgPico Plant book

Pico Plant
Pico Wave Power Plant, at Azores, on the island of Pico, was disconnected from the network on April 17, 2018 due to the partial collapse of the plant. The project to dismantle the plant had already been started, being prepared by both Portuguese utilities, EDA and EDP. 

Pico Plant has made a very valuable contribution to the promotion of wave energy research, development and innovation, both at national and European level and internationally, attracting more than 11 national and European projects. Pico Plant was part of two European networks of test infrastructure for wave energy technologies (MARINET AND MARINET2), promoting the access of international teams to the plant. The plant originated more than 100 international scientific articles and was associated with more than 8 doctoral theses and numerous master's theses and scientific internships.

In 2018, a book with the story of the plant and testimonies from those that visited or worked at the plant was published by WavEC (in Portuguese): https://www.wavec.org/contents/reports/brochura-central-do-pico-2018.pdf

WavEC Offshore Renewables organised its Annual Seminar 2018 on the challenges and opportunities in the offshore renewable and aquaculture industry in collaboration with the British Embassy in Portugal. The event took place on 4 December 2018.

 

 

 

MARINE SPATIAL PLANNING POLICY
The Marine Spatial Planning (MSP) policy is used as a decision making tool.

In March 2015, the Portuguese Law 38/2015 was created laying down the bases for the Planning and Management of the National Maritime Space (LBOGEM), defining the legal framework that allows for the implementation of marine spatial plans in the whole national maritime space, including the continental shelf beyond 200 nautical miles.

AUTHORITIES INVOLVED
The authorities involved in the consenting process are:

• Portuguese Environmental Agency (APA);
• Coordination Committee on Regional Development (CCDR);
• Energy and Geology Directorate-General (DGEG);
• Portuguese Electricity Utility (EDP).

CONSENTING PROCESS
Ocean energy projects in Portugal require the following licenses:

• License for water resources utilization – managed by the Portuguese Environmental Agency (APA). This license is the main consent required and can be authorized through a license or concession:
- A license is required for devices deployed for less than one year and for installed capacity below or equal to 25 MW;
- A concession is mandatory for more lengthy time periods. In this case, a competitive public examination must be carried out, starting with a public announcement by the competent authority.
• Environmental license – managed by the Coordination Committee on Regional Development (CCDR), which is the regional authority;
• License for the power production or grid connection – a request made by the developer to the Portuguese Electricity Distribution (EDP);
• Building license for infrastructure on land (e.g. substation, cable routes) administered by the municipal council of the area where the project is to be installed.

ENVIRONMENTAL IMPACT ASSESSMENT
An Environmental Impact Assessment (EIA) is not required if the project, including marine and terrestrial parts, is to be located outside the national ecological reserve, Natura 2000 sites and/or the national grid of protected areas.

However, this decision still has to be confirmed by the licensing authority. If any part of the installation is located in an ecological reserve, Natura 2000 or a protected area (within one of the previous location/sites), an Environmental Effects Assessment (EIncA) has to be performed. The EIncA is a less demanding administrative instrument than the so called EIA. The entity responsible for the decision on whether an EIA/EIncA is required is the CCDR if it is a license, or APA if it is a concession.

The baseline survey is usually made through desk based studies although some developers of the few projects that have been installed in Portugal have carried out some baseline studies as required in the declaration of the EIA.

Monitoring is usually part of the EIA declaration issued as part of the environmental license. In Portugal the onerous post-deployment monitoring have been required for some marine renewable energy projects. Evidences should be given in periodic reports that monitoring in being carried out, and its results are usually analyzed by the Portuguese Institute for Nature Conservation (ICNF).

LEGISLATION AND REGULATION
Whilst there is no over-arching dedicated consenting system for ocean energy, all the required consents have been adapted to better suit wave energy developments.

Decree Law 225/2007, of 31 May, amends previous legislation on electricity production to accommodate electricity production from renewable sources and establishes regulation on the EIA process for such kind of projects.

CONSULTATION
Consultation is usually required as part of the legal licensing process. It is usually made after the Environmental Impact Statement is delivered to the authorities for approval.

Advices are asked by the licensing authority to a number of statutory consultees namely Institute of Nature Conservation, port authorities and a number of public authorities responsible for marine resources management.

There are informal consultation activities implemented during the licensing process: usually developers prepare a number of informal public events to disseminate the project and collect the public feed-back on their activities at sea.

GUIDANCE AND ADVICE
Some information on parts of the licensing process exists in the internet as part of the authorities’ website. However there is no compiled information on all process and the developer is usually the manager of the project licensing procedures.

TEST CENTERS
Specific regulation for the Portuguese Pilot Zone – Ocean Plug – has been produced and provisionally approved by DGEG.
