Biomethane for France:
WELTEC Receives Order for Biogas Project with Gas Processing
French agriculture has a wealth of raw and waste materials that
are suitable for biogas plants. However, only half of the available materials
are presently used for energy production. Thus, ambitious development plans
have been drawn up: By 2020, the biomass share in the field of renewable
energies in France is to rise to about 50 percent.
No wonder that that the
number of RFPs for plant projects for the generation of energy from biomass is
on the rise. This affects the order pipeline of established biogas plant
manufacturers like the German WELTEC BIOPOWER GmbH. Meanwhile, the project list
includes about 30 French biogas plants. Some of these projects are rolled out
in cooperation with Méthalac from Lyon, France.
This expertise was one of
the reasons why WELTEC BIOPOWER and Méthalac received an order for a biogas
project with gas processing in summer 2014. The plant in the north of the
Franche-Comté region on the Swiss border will be completed in spring 2015,
after which it is expected to supply biomethane to the French natural gas grid
at a rate of 70 standard m³/h.

Thus, the plant stands
witness to the increasing importance of the processing of biogas to biomethane.
Though France only has five plants with gas feed-in, the population is growing,
especially in view of the ample supply of biomaterials. This is also the case
with the plant in Franche-Comté. The biomethane is processed from 6,000 t of
agricultural waste, such as cattle manure, pig manure, intertillage and starch.
These are digested in a stainless steel fermenter with a capacity of about
“To me, the tax advantage is
a major argument in favour of a WELTEC plant“, says David Peterschmitt, the
operator of the plant. He adds: “Bolted stainless steel containers are not
included in the calculation of the cultivated area. In this way, the assessment
base for the CFE land tax is reduced. This is a significant advantage over
Based on the personal
impression that he gained about the durability of established WELTEC plants
during a visitto Germany, the builder drawsattentionto another positive aspect:“The
tax advantage would evaporate if the maintenance costs were high. Accordingly,
the condition of the two inspected biogas plants built in 2003 and 2010
convinced me of the longevity of stainless steel as a material and confirmed by
decision to work with WELTEC.“
Together with Biogaz Services from
Metz-Tessy, Méthalac will be responsible, not only for the installation and
commissioning, but also for the maintenance of the WELTEC biogas plants. The
team boasts a wealth of experience, especially in connection with the employed
WELTEC material, and will ensure perpetually stable, economic operation. Once
word gets around about the pros of biogas and biomethane plants, the French
will succeed in making consistent use of their wealth of raw materials.
