Also biogas technology trading, project management and evaluation, feasibility studies market surveys and business plans, innovation and training. Mr. Ahto Oja has moderated several national and the international conferences on bioenergy, biogas and energy efficiency. Presentations are available at: We have identified most of the resources for biogas production in Estonia, potential is 350 million m3, which is 50% of the Estonian annual natural gas consumption, current production is 15 million m3. Currently most profitable is biomethane for transport, which market is emerging, 2 methane gas (compressed natural gas and biomethane CH4 95%) filling stations are in operation and app. 100 vehicles. We are interested on trade on bio-energy and biogas technologies and equipment, also joint companies for biogas/biomethane production, and trade on methane-gas vehicles.

Estonian biogas resource
The aim of the paper is to describe the current situation of the Estonian biogas
sector, to state the most important development obstacles, and to come up with topics relevant
for further discussion.

The six most important resource inputs for the production of biogas are: energy crops from
unused agricultural land; slurry and manure from livestock farms which are registered in
Estonian Agricultural Registers and Information Board; semi-natural grasslands;
larger landfills; biodegradable waste; and waste water sludge. Figure 2 shows the theoretically
producible biogas quantities (Nm3) in Estonia.
The total theoretical annual biogas quantity (545 million Nm³) could supply 264 000 households
(871 000 people, 1.25 MWh/person) with produced electricity (2 kWhel/Nm3) and 153 270
households (505 791 people, 3.23 MWh/person) with heat energy. The same amount of energy
expressed gasoline equivalent (60% methane concentration) would be 327 million litres which is
approximately one-half of the total quantity of transport fuel used in Estonia annually.

The paper also contributes to the development of the Estonian biogas sector in a broader scale – the generalizations that are made in the paper will be used in political analysis, development discussions, and in the work of the Estonian Biogas Association and other biogas institutions.
The biogas sector in Estonia is in an early stage of development, both in the sense of acquiring
know-how and implementing practical solutions. In Estonia, the resources of biogas would
theoretically enable to produce approximately 10% of primary energy based on biogas; the
percentage of resources that could be taken into actual use is around 37%. In reality, the amount
of Estonian biogas production is only around 11 million Nm3 of gas originating from landfills,
sewage sludge and slurry (liquid manure).
The biogas sector in Estonia is emerging. The production of biogas is a commercial activity, but it is
also inseparably connected to environmental protection and waste handling, which depends on subsidies.
