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 Company Profiles • The consortium will be composed of two companies: • Wave Dragon is a private Danish/UK based company working towards  Wave Dragon the commercialisation of wave energy converter (WEC) technology to  Seaweed Energy Solutions (SES) extract electricity directly from ocean waves. • Seaweed Energy Solutions (SES) is a Norway-based seaweed • The independent organisation, Bellona Foundation will also innovation and business development company. be involved. • Bellona Foundation is an independent non-profit organization that aims to mitigate against challenges of climate change through identifying and implementing sustainable environmental solutions.

☺ 20,000 hours operational track record ☺ Wave energy absorption performance verified ☺ It works! Power delivered to the grid ☺ Offshore wave energy is a reality Why farm seaweed? Rough introduction of seaweed market Total production 28 million ton. Annual growth rate 8-10%. Commodity Mton/y Main production from cultivation in Asia (95%) • 50% of the world primary production (phososynthesis) Marine fish 73 takes place in the sea Market value 8 billion USD Seaweed 28 • Still 99% of our food energy comes from agriculture on Markets: food (75 %), hydrocolloids (13 %), feed, Molluscs 22 land… fertilizers, cosmetics, pharmaceuticals and chemicals. Crustaceans 10 Salmonids 4 • 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

Markets and applications Dominating the entire cultivation cycle 1. Human food 3. Plant health & nutrition – Sea vegetables, snacks – Growth promoters – Salt replacement – Plant defense – Flavour – Macronutrients (N, P, K) – Texturizer – Micronutrients (Fe, Ca, Cu) – Trace elements 2. Health & nutrition 4. Specialty chemicals (humans and animals) – Alginate, carrageenan, agar – Gut health (fibers, prebiotics) – Alginate derivatives – Immune stimulation – Mannitol and derivates – Anti-oxidants – Fiber/textiles – Anti-inflammatory – Minerals – Anti-biotic – Protein – Vitamins 5. Industrial fermentation – Minerals – Biofuels – Fatty acids – Biochemicals – Skin health (cosmetics) – Single cell protein (SCP) – Animal fur and mucus health – Pharmaceuticals/bioactives (Integrated biorefineries) 13 14 SES Pilot 2015/16: 20 tons final food product SES exposed offshore farming vision(s) • Technical challenges (sea operations; wear on equipment; fewer days with work weather) • Logistics: longer journey times and expensive harvest/transport/delivery sequence Two distinct approaches analysed/considered: Passive survivability design (structures moving like seaweed) Active submergence in storms (wave power with classical farm designs) 16

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