Need for Energy Storage

Solar energy and wind farm systems would benefit from large-scale energy storage due to three factors, especially with large utility grid penetration of intermittent renewables:

• Limited by electrical transmission line constraints between the

source and demand.

• Lack of adequate electricity load at the time of large renewable

generation potential.

• Increased GHG emissions & local pollution due to use of fossil fuel

generators (e.g. NG turbine) to “firm” intermittent renewables.

– Use of RE & part load NG turbines may actually be worse than using full-load NG turbines alone.

Renewable Hydrogen Impact

• $118 billion in market revenues projected

2% of US energy currently goes through H2 more than 95% by natural gas reforming If 2050 US H2 projections can be produced from renewables, it could cut

45% of all US carbon emissions 2500 M metric tons of CO2

Electronics

Finding the Value Proposition

• Markets are large but customers want solutions

not a set of discrete technologies.

• Creative entrepreneurs are finding ways that

hydrogen fits and provides an investment return.

• Opportunities are very geographically specific.
• Pending incentive adjustments, especially in the

EU can help move things faster.

11

Market Based Opportunities

14

2015 – First U.S. Power-to-Gas Project

• Southern California Gas (SoCalGas), UC Irvine, NREL, & Proton
• Phase 1 – Unique 7 kW electrolyzer with proprietary DC-DC

converter and MPPT control system

• Provides a key research platform for testing PEM electrolyzer in

a direct DC mode of operation

• H2 being fed to four uses:

– Vented – Stored (at various pressures) – Into UCI-ELF natural gas pipeline – Into end-use combustion device

• Phase 2 – 60 kW electrolyzer
• Providing a larger production

rate of hydrogen and allows for 3X scale up

15

• University receives “Transmission Level Service” from

utility (defined by campus peak demand exceeding 500kW in any month during the course of a year)

• Current University demand charges represent 48% of

electricity spend or close to $1M/yr.

• 15MWh of power needed between 2:00pm and 9:00pm

to cover demand charges

• University has 4MW of installed wind power with over

20MWh being curtailed between 9PM and 6AM.

• Excess power from night needs stored for shifting to day

usage eliminating demand charges

• The following options were evaluated:

• Battery Option

– Evaluated but the cost was too high based on expected life target of 20 years – negative ROI at 20 years.

• Electrolyzer with Fuel Cell Option

– Based on fuel cell life of 7-10 years and a high price FC Capex, the project had a positive ROI at 15 years primarily driven by the use of the oxygen from the electrolyzer for the University’s NG boilers.

• Electrolyzer with Gas Turbine Option

– Electrolyzer with economical gas turbine delivered a 4.5 year ROI for this option. As above the oxygen value was considered for use in the boiler enhanced operation.

• 2MW electrolyzer with a 2.5MW gas turbine
• ption selected. Targeting Q2 2017 completion.

H2 Costs versus Li-Ion

CHBC White Paper, Power-to-Gas: The Case for Hydrogen

Key Takeaway: Even with a dedicated fuel cell for converting the stored energy back to electricity, H2 energy storage is cost effective at longer discharge times. Case 1: Dedicated fuel cell for converting stored energy back to electricity. Case 2: Hydrogen is transported via CNG distribution system and used in existing generation asset.

Kunia Village Microgrid Energy Storage Project

• 121 single family homes growing to 200 homes specifically for farm

workers – off grid.

• 200,000 square feet of commercial area leased to help pay for

expenses.

• Sewage wastewater to hydrogen.
• Solar installed on aluminum structures allowing for land underneath

to be used for agriculture and creating a greenhouse environment.

• Reduces price of water used for irrigation of crops by reducing
• verall cost of electricity.
• 20 year PPA with 98% uptime guarantee
• Create substantial reduction in electricity cost and improves power quality

moving from gensets to fuel cells.

KUNIA SUSTAINABLE AGRICULTURE VENTURE

• 16 acres of Greenhouse and AgIndustrial buildings for long-

term lease

• Community-Scale MicroGrid : 10 MW of Solar PV to power

irrigation wells and Village businesses with advanced battery and hydrogen energy storage technologies.

• Fixed energy prices for 20 years keeps costs for water low for

farmers

• Advanced wastewater treatment technology for recycling of farm

and food processing effluents

• Housing in the Village for low-income Farmworkers

Summary

• Real commercial opportunities are presenting

themselves globally to enable hydrogen as one

• ption for renewable energy storage.
• Legislative incentives are still needed to drive

wider adoption of the technology especially in Europe.

• As electrolysis costs come down additional

transportation and other markets begin to further

• pen under commercial terms.
