The document summarizes a joint project between Wave Dragon and Seaweed Energy Solutions to develop a combined wave energy converter farm and seaweed cultivation operation in Wales, UK. The consortium involves Wave Dragon, which develops wave energy technology, Seaweed Energy Solutions, a seaweed innovation company, and the Bellona Foundation, a non-profit environmental organization. The project aims to establish a 1 MW wave farm paired with an initial 80 tonne per year seaweed farm, and expand to larger commercial scale operations co-locating 45 Wave Dragon converters generating 180 MW paired with a 20,000 tonne per year seaweed farm. The combined operation is estimated to have significantly lower costs than individual wave or seaweed farms alone.

- 1. Final Project Presentation 30 & 31 August 2016 | Cork, Ireland Wave Dragon Seaweed Energy Solutions Wave Energy and Offshore Aquaculture in Wales, UK A MUS example: combined wave energy converters with a seaweed producing farm – utilizing the calm water behind the Wave Dragon Consortium Description • The consortium will be composed of two companies: Wave Dragon Seaweed Energy Solutions (SES) • The independent organisation, Bellona Foundation will also be involved. Company Profiles • Wave Dragon is a private Danish/UK based company working towards the commercialisation of wave energy converter (WEC) technology to extract electricity directly from ocean waves. • Seaweed Energy Solutions (SES) is a Norway-based seaweed innovation and business development company. • Bellona Foundation is an independent non-profit organization that aims to mitigate against challenges of climate change through identifying and implementing sustainable environmental solutions.

Power delivered to the grid ☺ 20,000 hours operational track record ☺ Wave energy absorption performance verified ☺ Offshore wave energy is a reality Why farm seaweed? • 50% of the world primary production (phososynthesis) takes place in the sea • Still 99% of our food energy comes from agriculture on land… • Seaweed farming is sustainable: no freshwater, land area or fertilizers are needed (limiting factors on land) • Wide range of market opportunities for seaweed biomass • Rapidly increasing interest in seaweed products and seaweed cultivation “Seaweed is possibly the largest unexploited resource in Europe…” 12 Rough introduction of seaweed market Total production 28 million ton. Annual growth rate 8-10%. Market value 8 billion USD Markets: food (75 %), hydrocolloids (13 %), feed, fertilizers, cosmetics, pharmaceuticals and chemicals. Main production from cultivation in Asia (95%) Commodity Mton/y Marine fish 73 Seaweed 28 Molluscs 22 Crustaceans 10 Salmonids 4

Description of projects Pilot project in Wales 1st Commercial project in Wales 2nd Commercial project; new location 3rd commercial project Wave Dragon 1 WD; 4MW 9 WD; 30MW 9 WD; 30MW 45WD; 180MW SES 80 tonnes/y 4000 tonnes /y 4000 tonnes/y 20 000 tonnes/y Key figures 3rd commercial project Wave Dragon 45WD@4MW = 180MW SES 20 000 tonnes/y Pay back 4.3 years IRR 24.4% • Wave Dragon and SES have solid track records in their fields • Joint MUS project WD/SES has been initiated upon invitation of MARIBE • SES can cultivate in areas otherwise difficult to work in or inaccessible • WD can serve as operational base for (seaweed) aquaculture • The combined wave energy and aquaculture farm has a significant better economy than stand alone solutions (~10% reduction in levelised cost). • MARIBE has facilitated significantly the exploration of this MUS, and provided valuable help and contacts for development of this vision • A WD/SES pilot seems realistic in Welsh waters within a short time frame, provided that appropriate funding can be obtained.

Land plants vs. seaweed cultivation 41 Sanggou Bay, China Mato Grosso, Brazil Challenges for cultivation in Europe 42 Situation: • Suitable (protected) sites limited move offshore • High labour cost mechanisation needed To realize the potential of seaweed biomass, new and innovative cultivation technology is needed… Exposed waters seaweed farming: Develop industry in easier waters and gradually move farther out to sea • Technically possible – shown in Frøya and Portugal • Forces and wear on the equipment • Need for new designs (structures/equipment) • Operation and Safety - fewer work days at sea • Logistics – transport and fuel; buffer storage Stepping-stone: IMTA 43 • Bioremediation Residual nutrients capture (seaweed as a biofilter in integrated aquaculture; large part (50%?) of the feed nutrients are lost in the sea) • Recreation of the natural ecologic processes (increased biodiversity) Attracts marine life, provide shelter and habitat www.salmonfarmscience.com • Positive effect on seaweed Better growth of the seaweeds close to the fish farms (nutrient availability) Aquaculture Technology Logistics and Operations Obvious synergies of salmon farming and seaweed! ¡Gracias! 44 Large challenges ahead… “One company cannot solve this alone” – need to work together www.seaweedenergysolutions.com
