Combining different energy sources and uses by  David Teichroeb Combining different energy sources and uses by David Teichroeb Presentation Transcript

  • Smart Energy NetworksDavid TeichroebBusiness Development, Alternative & Emerging TechnologyFuture of Energy Summit, Toronto, June 8, 2012 1
  • Innovating for Smarter Energy Grids Energy Exchanges Between Silos • Energy exchanges bring new economic, environmental , and operating flexibility to power grids • Power to Gas with H2 from electrolyzers • Renewable gas back to power Source Data: Rethinking Energy Conservation in Ontario, May 2010 Report 2
  • Established Green Energy • Approximately $3 billion invested in green and alternative energy • Wind Power - 1000 MW operating or under construction in Alberta, Sask, Ontario , Quebec & Colorado • Eight Projects • Solar – 150 MW in Ontario and Nevada • Three Projects • Sarnia Solar project at 80 MW is one of the largest in North America 3
  • Diversity with Alternative TechnologyComplement renewables, reduce costs, increase environmentalbenefits, and support technology innovation • Canada’s largest stationary fuel cell at 2.2 MW – Urban power for 1700 homes – Runs on natural gas or renewable natural gas without burning fuel Hybrid Fuel Cell @ Enbridge, Toronto, Ontario • Waste heat to Power – Four, 5 MW projects recovering gas pipeline compressor heat (NR Green Power) – Investment in Genalta Power to develop lower-cost technology for smaller sizes 5 MW Heat to Power Plant on Alliance Pipeline 4
  • Power to Gas; Seasonal Electricity Storage• Off-Peak electricity to hydrogen with electrolysis of water PEM Electrolysis• Blending of hydrogen with methane in gas grid Natural Gas Network• Blended gas in cavern or pipeline Cavern Storage• Blended gas to electricity at peak time / peak season CC-Turbine 5
  • Storing & Transporting Electricity with Same Solution Distributed nature of pipelines affords Power to Gas TWh-Scale with connectivity across province Can charge and discharge by leveraging high pressure gas networks • Power to Gas breaks many of the technical limitations of conventional storage • Charging is possible through a distributed network of pipelines • Seasonal, TWh storage is possible with extensive gas cavern storage assets Extensive gas transmission from southwestern and northern Ontario • Power is managed in both offers congestion relief time and geographyExtensive Gas Storage in Southwestern Ontario- Ontario underground storage in excess of 200 billion cubic ft 6
  • Conclusions “Power to Gas” part of smart energy grids• Align the flexibility and scale of natural gas grids with the needs of the electricity network.• Stabilize power grids with growing mix of intermittent renewables• Cost efficiencies - pipelines, storage and gas power plants already exist• Seasonal electricity storage with hydrogen• Alternative transmission network with pipelines (relieve congestion) Source: 7
