[Gasification] Bongo: Putting biogas in to the grid

[Bruno M.]

Maybe not of interest to all, since many gasifiers and AD systems
are mend for direct and local use of the gas,

This 12 page PDF document dd 2006 is about how
European gas utility companies should prepare to
allow al kinds of biogas in to the grid ( of natural- ) gas.
And about how the quality of biogas should be, to be fit to go into the grid.
BONGO is a project under development, so not finished jet.

BIOGAS AND OTHERS IN NATURAL GAS OPERATIONS

                     A PROJECT UNDER DEVELOPMENT

ABSTRACT
There is a strong political drive to develop gas from biomass and all 
other types of nonconventional
gases (in this paper summarized as "biogas") as an important energy 
source in the nearfuture
energy system. Biogas has the potential to increase the security of 
energy supply and, taking
into account the total energy and emission chain, the utilization of 
biogas will not contribute to the
global emission of greenhouse gases. Therefore there is an obvious 
need to examine the potential of
the existing natural gas system for the accommodation and delivery of biogas.
Also, there exists a legal framework in which biogas is important for 
the natural gas industry.
The European directive 2003/55/EC aims to open the existing natural 
gas grid for gas from sources
other than natural gas, including gas from renewables.

As the initial composition, and consequently the physical and 
chemical properties, of biogas
may differ significantly from those of natural gas, the organizations 
involved in the chain of
transmission-distribution-end user should be prepared to cope with 
biogas. In order to be able to use
biogas widely in domestic, residential and industrial applications, 
the technical consequences and, in
particular, the safety and pipeline integrity aspects related with 
the addition of biogas to natural gas
need to be addressed. As biogas will be an increasingly important 
fact of life in Europe in the near
future, and as the potential problems associated with it are very 
complex and broad, it is in the interest
of the European natural gas industry that this issue be tackled 
jointly and in strong collaboration with
all stakeholders. With networks becoming increasingly interconnected 
a pan-European approach and
a common position on the definition of technical rules and safety 
standards is required.
Under the guidance of GERG - the European Gas Research Group, and 
following the actions
carried out by MARCOGAZ concerning technical requirements for biogas 
injection in gas grids,
Gasunie took the initiative to raise the BONGO project: "Biogas and 
Others in Natural Gas Operations"
and it is our view that the BONGO project will be THE project that 
prepares the wider European
natural gas industry for biogas.

BONGO is a project under development, aimed at defining quality 
specifications for biogas
access to the gas transmission and distribution system. This will be 
done by overall risk assessment,
which will fill the gaps in our knowledge related to the addition of 
large volumes of biogas to the
existing natural gas system. It will investigate whether biogas will 
affect the safety of normal gas
operations including, storage, injection, transmission and 
distribution and end-use. A thorough system
analysis will ensure that these activities can take place with 
acceptable effects on the integrity of the
existing natural gas grid, the value of the product as a feedstock 
and, most important, with
acceptable operational, safety, health and technical consequences for 
the end-user.
This paper describes the BONGO project in more detail, with 
objectives, approach, scope,
basic set-up, planning and partners explained.
