Agromethane HELLAS was founded in December 2010 by Konstantinos and Alexandros Alexandridis, engineers with many years of experience in natural gas transmission and distribution technologies.

The initial scope of the company’s activities was to transfer the research wealth that exists in the field of Bioenergy at a domestic and international level to the real needs of production, in view of the objectives of effective environmental and energy management.

The two main areas on which the research and construction activity of the company was initially focused were the anaerobic digestion of biomass and the co-generation of electrical and thermal energy. Of course, the complex production plants had to incorporate various additional and auxiliary functions such as the collection, storage and pre-treatment of the feedstocks (biomass), the treatment, intermediate storage and disposal of the residue (digestate), the treatment (desulphurization, dehydration, compression) of the biogas before entry in the cogeneration unit, as well as numerous safety facilities against overpressures, overheating and leaks of methane to the atmosphere.

With the accumulated experience in the organization, construction, operation and management of biogas units, Sustainable Engineering reorients and expands the scope of its activities in the production of Biomethane (renewable natural gas) as a final product, diversifying both the production methodologies (to the anaerobic digestion are added the gasification and methanation of hydrogen) as well as in the end-use sectors of biomethane (transportation, heating and industry are added to power generation).

Already in the middle of the decade, it had been established internationally that the choice of Biomethane production instead of electricity generation was not only more energy efficient, but also had a greater contribution (about 4 times more) to the reduction of greenhouse gases (GHG). But it took the recent escalation in natural gas prices to lead European Union states to mandate the production of large amounts of biomethane as one of the measures to address the gas supply crisis (REPowerEU).

Agromethane HELLAS, anticipating that soon this need will be recognized by the Greek state which will determine the measures and the institutional framework for supporting Biomethane, has the ability to offer integrated solutions for the production and distribution of biomethane on the market.

With the accumulated experience in the organization, construction, operation and management of biogas power plants, Sustainable Engineering reorients and expands the scope of its activities in the production of Biomethane (renewable natural gas) as a final product, diversifying both production methodologies (gasification of biomass and methanation of Hydrogen are added to the traditional Anaerobic Digestion) as well as the end-use sectors of biomethane (transportation, heating and industry are added to power generation).

The gas transmission and distribution networks do not have the density and coverage of those of electricity. As a result of this, it is difficult to transport the energy product (biomethane) produced in the units to the consumers. For this reason, various transport methods are applied (injection into transmission networks, injection into distribution networks, land transport in compressed form, transport in liquid phase, etc.). In these sectors, Sustainable Engineering, thanks to the 30 years of experience of its  in the distribution of Natural Gas, can offer integrated solutions for the production and distribution of Biomethane.
