1 MICROGRID 2015 Minimizing Environmental Impact in an Off-Grid System: Solar + Sustainable Storage TERRY HOLTZ OCT 2015

2 What are we talking about today? A tremendous amount of development, both technical and market, is being directed for adding energy storage to PV in grid-connected homes, commercial buildings, and at utility-scale. There is another set of applications, typically off-grid, where the value of energy storage integrated with PV offers both economic and substantial environmental benefits. This presentation will highlight several project installations and the resulting environmental benefits using Aqueous Hybrid Ion (AHI) batteries with PV across multiple geographies worldwide.

8 Typical Off-Grid Installation Modeled using software from: + Modeling the thought process of a typical off-grid residential application: 1. Start with a diesel generator just how bad is it? 2. What happens when we add PV? Costs / fuel usage (CO 2 ) 3. How much better is it when adding energy storage? 4. What do the cost and economics look like if we eliminate the diesel altogether? 1. Diesel 2. Diesel + PV 3. Diesel + PV + Storage 4. PV + Storage 10 kw diesel generator 10 kw diesel generator 5 kwp PV array 10 kw diesel generator 5 kwp PV array 3 kw / 25 kwh storage No diesel generator 10 kwp PV array 4 kw / 50 kwh storage 10,500 L diesel used = MT CO 2 PV saves 3,400 L fuel 30% CO 2 reduction from diesel only Storage saves an additional 6,500 L fuel 95+% CO 2 reduction from diesel only It s possible to eliminate diesel altogether by doubling size of PV array and energy storage Aquion Energy, Inc.
