Our Interest in Energy Storage • There are many benefits from energy storage:

– Time shifting – Must offer, must comply – Less curtailment – Reduced T&D losses – Deferring T&D upgrades – VAR (reactive power) support – Peak shaving – Ramp support – Improved power quality – Improved ancillary services – Renewable energy integration

Alberta Wind and Solar Potential

• Currently >1.1 GW installed wind • Potential to increase significantly • Very little installed solar PV, but • Alberta’s solar resources comparable to

Germany, which has >31 GW installed

AESO Wind Forecasting Study

• Wind power forecasting pilot project (2006-2008): – To trial wind power forecasting methods and

providers – To identify the most effective method(s) to forecast

wind power in Alberta – To identify the most effective providers of wind power

forecasts – To educate industry on the capabilities of

wind power forecasting in Alberta • Industry working group was formed by AESO • Report available on AESO website

Study: Energy Storage: Making Intermittent Power Dispatchable

• Lead by Alberta Innovates – Technology Futures • A primary goal: Assess the financial viability of

energy storage in Alberta • Technologies evaluated • Hind-cast revenue model:

– Behind-the fence storage – 2007-2010 hourly pool price – 2 technologies: CEAS, NaS batteries – 2 wind operations: Castle River, Chin Chute – 2 strategies: time-shifting, firming

Study: Energy Storage: Making Intermittent Power Dispatchable

• Recommendations: – Merchant storage: additional revenue? – Ancillary services market participation? – Nameplate capacity enhancement? – Intertie congestion relief? – Storage size optimization

• Optimum power (MW) to energy (MWh) ratio?

• Further work initiated: – Techno-economics of power-to-gas (AITF,

ADOE) – Presentation this afternoon

Feasibility of high temperature electrolysis for energy storage

• Project co-initiated and co-funded by AI-EES and AITF, conducted by AITF

• Aimed to: – Establish how high temperature electrolysis could

contribute to energy storage in Alberta – Establish status of technology – Develop a path forward towards deployment of

the technology in Alberta

Why high temperature electrolysis

• Hydrogen is seen as a key energy storage medium

• Compared to low temperature electrolysis, high temperature (600°C-1000°C) consumes less electrical energy (more thermal)

• Carried out in a solid oxide electrolysis cell (reversed solid oxide fuel cell)

Current status of high temp electrolysis

• High temperature electrolysis development is ongoing and interest is increasing – Main issues

• Cell reliability • Cell durability

– Key development areas • Cell design • Cell material optimization

• Current development status renders cost estimates highly uncertain

• Outlook – AITF has proposed a set of activities which would aim

to build a field scale demonstration prototype in 5 years
