Context: energy transition from fossil to renewable
• COP21: Worldwide engagement to stop global warming
• Germany is 20 years away from 100 percent renewable power
• In practice, however, a number of related problems would
need to be solved, especially power storage and grid lines.

Global Warming
We need these:

Focus point: why we need to store energy?
• Sun is shining only during daytime
• Wind does not blow always
• Peak demand is in the evening
• Production and demand are not in the same time,
we need to store energy
• Hydrogen is a clean, available, recyclable energy carrier

Energy carrier: H2 gas, how to make it, how to use it?
• Producing by Electrolyze
2H2O  O2+2H2
• Storing under pressure to reduce storage volume
• Burning in Internal Combustion Engine
2H2 + O2
• Generating electricity using a Fuel Cell
H2
Air


O2
2H2O
• Advantage: burning Hydrogen produces no CO2, only water!!

Storage types - Two main technologies:
Pressurized gas
Metal hydride
• Room temperature storage
• Metallic tanks
• Composite tanks Type III, IV
• Hydrogen is stored in a specific
conditioned metallic powder
• Absorption/Desorption is heat
dependent
• Easy to handle (2-5bar)
• Heavy

Metallic tanks for pressurized gas
• Heavy
• Medium pressure
• Usually big volume or modular stack

Type IV composite tanks for pressurized gas
• Made by filament winding
• Inside: Polymer liner,
Outside: Carbon and glass fiber composite
Ends: metallic bosses for connecting pipes
• After laying down the fibers on the liner,
the structure needs to be dried and cured
in an owen.
• Pressure resistance
• Light weight

Metal hydride storage tanks
• Hydrogen is stored in a metallic
powder compound which stores
the gas in a smaller space than the
gas itself occupies at the same
pressure.
• Absorption needs cooling
• Desorption needs heating
• Low pressure (2-5bar)

Applications: what are the specific needs?
• Mobile : tanks powering transport vehicles: cars, moto-cycles,
scooters, trucks, bicycles
• Nomad: tanks powering appliances that can be transported
• Trolley minibar for a train
• Autonomous lamps or cameras
• Stationary: not moving tanks: telecommunication relay, remote
locations

Applications: Mobile
High pressure composite tanks for
greater autonomy (500km)
• Light weight
• Very high pressure 700bar
• Technical difficulties and higher
costs to handle high pressure
Hydrogen storage solutions by Mahytec
Low pressure metal hydride tanks for
convenience and short distances
• Direct refill from electrolyser (30bar)
• Pressure range 2-5 bar
• Indefinitely recyclable
Hyvolution Paris 04/02/2016
Applications: Nomad
• Small volume
• Low pressure (easy handling)
• Bigger autonomy than battery
• No CO2 emission

Applications: Stationary
• Big volume, traditionally steel tanks have been used
• Low pressure (<50bar)
• Long lifetime,
• Weight may be a priority
H2 autonomous room
Provides power to the
shelter at 2600m high
Composite tank:
Light weight,
Modular
