Enbridge’s Footprint
• Employ 10,000 in Canada & U.S.
• Largest liquid pipeline operation
• Natural gas transmission and
Canada’s largest gas distributor
• Electricity transmission
• ~ $ 3 Billion in Green and
Alternative energy
• Includes fuel cells, geothermal
power, run of river hydro, heat
to power, etc.
• More than 1300 MW of wind
and solar assets operating or
under construction
• Recent Investments include
Hydrogenics and Temporal
Power for electricity storage &
Morgan Solar for CPV

Investing in Ontario Companies
Morgan Solar – Toronto, Ont.
• Concentrating Solar Photovoltaic (CPV)
– Sun tracking technology
– Good potential for grid parity power costs
Hydrogenics, Mississauga, Ont.
• Electricity Storage with Hydrogen
– Power-to-Gas uses hydrogen electrolyzers for
bulk storage of surplus renewable power
– Store renewable Hydrogen in natural gas grid
Temporal Power, Mississauga, Ont.
• Flywheel Energy Storage
– Flywheels enable correction of short-duration
power imbalances
– Mechanical battery storing kinetic energy

Innovating for Smarter Energy Grids
Energy Exchanges Between Silos
• Energy exchanges
bring new economic,
environmental , and
operating flexibility to
power grids
• Power to Gas converts
renewable energy to
hydrogen with
electrolyzers
• Renewable gas back
to power

Power to Gas; Seasonal Electricity Storage
• Off-Peak electricity to hydrogen with water electrolysis
• Blending of hydrogen in pipeline grids
• Store renewable gas in cavern or pipeline
• Blended gas to electricity at peak time / peak season
• Alternative end-use as green heat or upgrading

Flexibility of Power to Gas
1) converts surplus, non-emitting electricity to hydrogen with electrolyser, 2)
bank energy in pipeline infrastructure, 3) transmit energy by pipeline, and 4)
economic discharge of renewables at the time and place it is needed
