1. A unique technology innovation to produce renewable
fuels and store energy.
Green Energy Technology

2. Storing Renewable Energy Difficult?
• Currently there is a need for alternative energy solutions of
high efficiencies, low costs and without technological barriers
• Major problem concerns renewable energy storing
• Wind and solar energy are produced when there is no use for the
produced energy
• Current methods of storing renewable energy are high cost and low
capacity
• Renewable energy is not a viable option unless the energy
can be stored cost effectively on a large scale
• Need to produce carbon neutral renewable transportation
fuels is also a growing trend

3. New Green Energy Technology by MTT
• Our solution to mitigate climate change is to utilize renewable
energy sources to produce synthetic natural gas via microbial
methanation of hydrogen that is produced by renewable energy
• With our carbon neutral technology it is possible to convert
renewable energy, e.g solar and wind power to synthetic
natural gas
• Our technology can also be used to reform biogas and syngas
to pure methane
• Produced methane can be utilized in the readily available
natural gas infrastructure

4. New Green Energy Technology by MTT
• MTTs technology provides a simple, low cost solution to
produce clean methane fuel
• We have a specifically designed solid support bioreactor
which forms methane (CH4) by using known natural
methanogenic archaea
• Methanation of hydrogen occurs with the aid of carbon dioxide
(CO2) for example from an industrial emission
• The advantage is that the CO2 is not discharged into the
atmosphere resulting into completely closed CO2 cycle

6. Exploitation Possibilities
• There are several exploitation possibilities depending on used
feed gas sources and intended application
• When storing renewable energy or producing transportation
fuel from renewable energy source there are three main steps
1. The production of hydrogen by electrolysis using a renewable energy
source
2. Produced hydrogen is converted to methane via microbial methanation.
The required CO2 can be obtained for example from an industrial
emission
3. The utilization of the produced methane gas

7. Exploitation Possibilities
• The technology can be used to reform CO2 containing syngas and
biogas to pure methane with the aid of hydrogen
• Hydrogen can be produced by renewable energy sources
• Importantly our technology can be used to capture of CO2 from CO2
emission source
• The basic method is the same as in previous examples: hydrogen reacts with
the aid of CO2 to form methane
• The feed gas sources of hydrogen and CO2 can be selected freely
which makes our technology extremely flexible
• Methane can be futher utilized for example in bacterial protein
production or chemical industry (plastics, polymers etc.)

9. Methane has major advantages
• Methane as energy carrier has major advantages concerning the
safety and storage issues
• Hydrogen forms highly explosive mixtures with air at very low quantities and
storage of hydrogen is a difficult task
• The energy density by volume of hydrogen is very low and hydrogen
permeates through materials, even steel
• Because of these limitations it is more convenient to transform the produced
hydrogen to methane gas which is safer to store, transport and utilize
• When using methane gas the existing natural gas infrastructure can
be utilized
• additional cost of building a completely new infrastructure can be avoided
• Methane gas also has the highest energy storage capacity of the
current energy storage technologies

10. Simple, Cost-Effective and Robust
• Compared to metal catalyst based technologies our solution is
simple, cost effective and robust for impurities
• Cost on average <$10 000 + automation
• Our solid support reactor is maintenance free and energy
losses can be minimal
• Energy losses from stirring of the microbe mass can be avoided as the
stirring is not required
• Advantages of our technology are also the low operating
temperature and pressure
• Microbial methanation reaction occurs at 55°C (131°F) and at
atmospheric pressure.
• The reaction releases energy in the form of heat. Heat can be captured
and utilized which improves the total system efficiency
