1 Final Project Presentation 30 & 31 August 2016 Cork, Ireland Seaweed Energy Solutions Wave Energy and Offshore Aquaculture in Wales, UK Consortium Description The consortium will be composed of two companies: Seaweed Energy Solutions (SES) The independent organisation, Bellona Foundation will also be involved. A MUS example: combined wave energy converters with a seaweed producing farm utilizing the calm water behind the Company Profiles 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.

2 The technology SES PilotFrank2014/15: 100 tons Neumann, Technology and Cultivation Hans Christian Soerensen, PhD, Chairman of the board Erik Friis-Madsen, MSc, CEO Flexible system with 16 LLs; 200m each Innovative substrates; industrial hatchery 6 AN OCEAN OF OPPORTUNITIES The Principle Wave climate - Power - Production 12 kw/m 1.5 MW 4 GWh/y/unit 24 kw/m 4 MW 12 GWh/y/unit 36 kw/m 7 MW 20 GWh/y/unit 48 kw/m 12 MW 35 GWh/y/unit Wave reflector Reservoir Turbine outlet Illustration: Ocean Forest - no reproduction without written permission Waves overtopping the doubly curved ramp

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

4 Markets and applications 1. Human food 3. Plant health & nutrition Sea vegetables, snacks Salt replacement Flavour Texturizer 2. Health & nutrition (humans and animals) Dominating the entire cultivation cycle Growth promoters Plant defense Macronutrients (N, P, K) Micronutrients (Fe, Ca, Cu) Trace elements 4. Specialty chemicals Gut health (fibers, prebiotics) Immune stimulation Anti-oxidants Anti-inflammatory Anti-biotic Protein Vitamins Minerals Fatty acids Skin health (cosmetics) Animal fur and mucus health Pharmaceuticals/bioactives Alginate, carrageenan, agar Alginate derivatives Mannitol and derivates Fiber/textiles Minerals 5. Industrial fermentation Biofuels Biochemicals Single cell protein (SCP) (Integrated biorefineries) 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

5 Key figures Description of projects 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 Conclusion Pilot project in Wales 4000 tonnes /y 4000 tonnes/y 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. 45WD@4MW = 180MW SES tonnes/y Pay back 4.3 years IRR 24.4% tonnes/y 3rd commercial project Backup slides

11 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 Mato Grosso, Brazil Need for new designs (structures/equipment) 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 Sanggou Bay, China 42 Gracias! Stepping-stone: IMTA 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 of salmon farming and seaweed! Large challenges ahead One company cannot solve this alone need to work together
