HELECTOR’s “Dry” Fermentation Technology
Placing the substrates into the empty dry fermenter (e.g. wheel loaders, strewing carriages)
Warming by the start of the aerobic degradation process (aeration from the ground)
Conditioning for the following fermentation
Ventilation stop and start of the percolation
As soon as the required biogas quality in the dry fermenter is achieved the exhaust air pipe is shut
and the biogas pipe is opened.
The biogas production in the dry fermenter reaches the maximum and then decreases slowly. The
methane content increases constantly and reaches values of up to 80 %
Stop of the percolation, dripping and drainage of the substrates
Aeration of the dry fermenters, interruption of the anaerobic process
“Garage” type fermenter
Electricity export
“Dry” vs. “Wet” Fermentation
Significantly lower water requirement No mashing requiredEffluent free operation possible
Lower process energy requirementno mixing mechanism requiredMinimal electric and thermal energy requirement
Less movable machine partsless material wear
Modularly extendable plants
Synergie in the use of agricultural equipment (e.g. wheel loaders, tractors, mixing carriages, manure spreaders etc.)
Simpler (stackable) storage and treatment of digestate
No heating of the dry fermenters
Current status of Biogas Projects in Greece
• Despite the high potential in Greece, currently the greatest percentage of the installed capacity of plants utilize biogas from landfill sites and sewage treatment facilities (39.9 MW)
Athens Ano Liosia Landfill, 23.5 MWel
Thessaloniki Tagarades Landfill, 5.05 MWel
Athens Waste Water Treatment Plant,
Psytaleia Island, 11.4 MW

Contribution of Biogas projects
Use of a renewable & sustainable source for Heat & Power production
Independence from fossil fuels & electricity imports
Creation of working places during the construction & operation process
Profitable activity for local farmers associations
Reduction of animal farming & food industry environmental impact (odors, uncontrolled byproducts disposal, greenhouse effect impact)
Integrated solution for Energy recovery & Management of Waste and Industrial activities byproducts
Constraints in Biogas Projects Development in Greece
Feedstock supply chain issues•Ensuring continuous supply over plant’s lifetime•Great dispersion of primary sources•Need of a well structured logistics mechanism•Dependence on “others” activities (Farmers, Industries, etc.)
Obstacles in Environmental licensing
Insufficient Projects’ financing •Lack of experience in business risks from biogas projects operation•Banks are reluctant for financing due to the current economic situation in Greece
Lack of synergies. Investments in Biogas Plants would be more attractive in case of plant integration with other activities:‐District Heating of local residences or industries‐Green houses heating
Thoughtless Renewable Energy Plants installation requests from anyone ‐Application’s accumulation in authorities‐Commitment of power grid lines ‐Delays in “serious” investments
Financing Issues –Problems Identification & solutions
No risk assessment & management in main issues such as supply chain, licensing obstacles, technology use. Business plans should be very analytical and accurate on these issues
Greek Banks do not have the required experience in relevant projects – And in the current situation nor the necessary liquidity.
Great delays in the absorption of subsidies resources
Sense of insecurity for “feed in tariffs” levels in long term basis – Extra taxation in renewable projects as in 2012. Need of clear warrantees in pricing policies by the state.
Legislation Framework for Biogas Investments in Greece
Land use framework for renewable energy
projects
Law 3468/2006,3851/2010•Licensing procedures•Feed in tariff policies
Legislation for organic waste treatment
Feed in Tariffs
•Biogas plants from animal & agricultural waste < 3 MW – 220 €/MWh•Biogas plants from animal & agricultural waste >3 MW – 200 €/MWh•Biogas plants from other sources (MSW treatment, sanitary landfills, waste water treatment plants) – 99.45 €/MWh
