The 'Biogas
to CHP' concept is shown in Figure. Biogas is produced
in a biogas plant converting organic matter
(manure) into biogas. The biogas is
cleaned/upgraded to natural gas standard and
mixed into the existing NG-Grid.
The
biogas/natural gas is transported by the
existing natural gas grid to a region containing
say minimum 300 households that are equipped
with fuel cell systems for combined heat and
power supply.
The natural
gas/biogas is reformed to pure H2 at
a central reforming station located close to a
cluster of households.
The
hydrogen is transported from the reformer
station to the household through a hydrogen
grid.
The
hydrogen is converted to heat and electricity by
a fuel cell
CHP
in the household.
