2 Presentation includes: RheEnergise Innovation: A High-Technology Fluid The Potential Market for Pumped Energy Storage Test Results Mapping studies Supply Chain Opportunities Next Steps 2

3 The High-Technology Fluid Density 2.5 times water Viscosity cp 70 Abrasion: Mohs hardness of 3.0 Benign, non-toxic, non-corrosive, non-reactive Available and affordable 3

4 Why use a High-Density Fluid? Pumped Energy Storage Basics Power = Efficiency x Fluid Density x Flow rate x Gravitational acceleration x Head Already excellent 80% + Who s explored density? A variable affecting cost Too difficult to alter Site Dependent 4

5 Why use a High-Density Fluid? For given head the High-Technology Fluid provides 2.5 times the power. For a given volume of storage it provides 2.5 times the energy. For power equivalence penstocks, valves, turbines etc. will be considerably smaller. Opportunities for pumped energy storage in markets with minimal water resource. 5

6 Opportunity Energy Storage Market To Hit $50bn by 2020 Remember: Hybrid Solar/ Wind and Energy Storage to reach $1.5bn by 2024 Total Global energy storage today is only 175GW of which pumped hydro is 168GW. 30% more than all pumped hydro installed globally to date. Energy Storage CAGR (Annual Growth Rate) of 20% Energy storage investment: 1,291GW by (BNEF) UK: 49GW energy storage by 2050 (4% global total). 83% supplied by renewables. (BNEF) Battery Energy Storage Market To Reach 250GW by 2030 (2.5GW today) 1,000GW energy storage and 5,000GW renewables by 2030 and 3,000GW energy storage by (IRENA) 6

12 Pumped Hydro Locations Pumped Hydro correlated with regions where rainfall is over 100cm/ year. Approx 25% global land mass. RheEnergise opportunities in the other 75% 12

13 Mapping Studies: Site Numbers Constraints: No more than one site in any 5km x 5km square No more that 1.5km between top & bottom store tanks 13

14 Mapping Studies: Site Numbers 3 times as many sites at 100m head than at 250m head (m) 14

15 Mapping Studies: UK Site Numbers Constraint mapping includes: ANOB/ SSSI etc. Rural/ Urban Proximity to: o Grid and demand o Road & ports o RE generators Out of 8,962 identified sites, modeling suggests: 624 on-grid sites 40 off-grid sites 7.5% with suitability rating over 60% 13 GW / 40 GWhstorage potential 15

Penstocks: > 100 sites / annum > 150m annual revenues Civil Engineering: 400,000 / MW construction value. 2,000 MW/ annum installed. 800m / annum revenue. Logistics: 100 sites/ annum > 200m annual revenue. 16

17 Why RheEnergise Pumped Energy Storage? 2.5 x lower head required for power equivalence. > 300% more siting opportunities. Storage size 2.5 x smaller than water. Civil engineering costs lower. Accesses ancillary service markets. On-grid, Off-grid, Renewables Colocation. Eases grid constraints allowing additional connections / utilisation. 60+ year lifespan potential. Overcomes environmental challenges associated with large scale pumped hydro. Levelised cost (at maturity) 35% below Lithium-Ion batteries (20 year calculation). Efficiencies comparable to conventional pumped hydro. No parasitic cooling loads associated with batteries. New markets in hot, dry climates. Smaller distributed projects (5MWp to 50MWp) Fast consents,. Fast construction. No water extraction licenses. Commoditised offering, lowering costs. 17
