2 Vision and Mission Our Mission: Develop, sell and integrate large Li-Ion battery packs for maritime/offshore applications Deliver consultancy services in this and adjacent sectors. Our Vision: We want to be unique and leading in cost-effective and customized Li-Ion battery solutions, first in Norway and later globally.

3 Why batteries in maritime applications? Reduced fuel consumption Reduced emissions Reduced maintenance costs Enables utilization of renewable energy Improved dynamic response Improved cost effectiveness

4 History of Li-Ion battery technology Initial work on Li based rechargeable batteries, original patent for LiCoO2 in 1979 by John Goodenough First demonstration of a Li-ion battery in the laboratory LiMn2O4 intercalation demonstrated LiFePO4 and LiMn2O4 intercalation demonstrated First mass production of Li-ion battery cell: LiCoO2-Soft carbon for Sony TR-1 camcorder. Long life EV batteries based on NMC chemistry High Power Li-ion for power tools: Sony, E-One Moli Energy, A123 Maritime usage of NMC based Li-ion batteries for hybrid operation Commercial introduction of NMC battery chemistry in EV & PHEV 1970 s 1980 s 1990 s 2000 s 2010 s Grenland Energy delivers the world s first large high-power maritime battery pack Li-Ion batteries are still a comparably «young» technology and the potential has not yet been fully exploited. There are still unknown factors and lots of innovation potential

7 The main factors for a safe and cost effective battery system Safety aspects: A large variety of cell chemistries and formats exist on the market, and not all are perfectly suited for maritime applications. Thermal events can have catastrophic impact with large battery systems. Operational conditions for the battery need to be carefully considered when designing the system. Monitoring and control systems need integrated functional safety features and proper system integration with other vital control systems in the application. Safety is the sum of balanced system properties (cells + mechanics + electric + control system) - «Intrinsically safe chemistries» do not exist! Cost aspects: A battery system is a considerable investment. Correct dimensioning to satisfy operational profiles over lifetime is key to profitable applications. An optimized energy-to-power ratio on cell level helps to avoid oversizing of battery systems. Lifetime modelling and testing with operational profiles gives indication on expected lifetime under given operational conditions.

8 Fully customizable system, yet modular and based on standard components. Power-to-Energy Ratio: large variety of available cell chemistries to satisfy exactly the applications needs. Modular: series or parallel configuration possible to achieve desired voltage or power characteristics Scalable: Multiple parallel string architecture to achieve capacity requirements Expandable: redundant systems with multiple MWh possible High Energy High Power Expandable Adjustable Power-to-Energy Ratio on cell level Other System level features: Dynamic Master/Slave architecture: String-individual monitoring with built-in redundant system control functionality makes additional controller unnecessary Optional remote logging and diagnostics Highly adaptable to customer interface and functions Scalable Modular

9 The importance of the right Energy-to-Power ratio Apart from uncompromised safety and redundancy, space and weight are important factors in maritime and offshore applications. The right energy-to-power-ratio is the key to the optimal solution. Example Applications Solution with High Energy System Solution with Medium/High Power System kwh (0,4 0,8 C) Optimal solution - Economically Unattractive kwh (0,5 1 C) Non-Optimal space/weight 600 kwh (0,7 2 C) Customized power/energy ratio Adaptable to retrofit applications Optimal solution kwh (0,4 0,8 C) Oversized battery needed to satisfy power demand Non-Optimal solution <400 kwh (>2 C) High power from small systems Optimal solution

10 Not just paperwork A comprehensive guideline In a cooperation project with DNV GL (TRANSNOVA funded), Grenland Energy has contributed to the recently published Guideline for maritime battery systems. The existing tentative rules for battery powered vessels are fully consistent with the newly published guideline.
