Global Warming
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. (http://energytransition.de)
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

H2
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 • Generating electricity using a Fuel Cell
• Advantage: burning Hydrogen produces no CO2, only water!!
2H2 + O2 2H2O

Storage types - Two main technologies: Metal hydride • Hydrogen is stored in a specific
conditioned metallic powder • Absorption/Desorption is heat
dependent • Easy to handle (2-5bar) • Heavy
Pressurized gas • Room temperature storage • Metallic tanks • Composite tanks Type III, IV
Hyvolution Paris 04/02/2016 Hydrogen storage solutions by Mahytec
Metallic tanks for pressurized gas
• Heavy • Medium pressure • Usually big volume or modular stack
Hyvolution Paris 04/02/2016 Hydrogen storage solutions by Mahytec
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
Hyvolution Paris 04/02/2016 Hydrogen storage solutions by Mahytec
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
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 Hydrogen storage solutions by Mahytec
Applications: Nomad • Small volume • Low pressure (easy handling) • Bigger autonomy than battery • No CO2 emission
Hyvolution Paris 04/02/2016 Hydrogen storage solutions by Mahytec
Applications: Stationary • Big volume, traditionally steel tanks have been used • Low pressure (<50bar) • Long lifetime, • Weight may be a priority
Composite tank: Light weight, Modular
H2 autonomous room Provides power to the shelter at 2600m high
