Samenvatting:
Within this paper the technical, economic and environmental potentialof
cofiring of biomass and waste in natural gas fired power plants is addressed.
The aspects that have been evaluated are the availability, contractability
and
costs of biomass and waste for energy purposes, the thermal conversion
concepts that can be used to cofire biomass and waste in natural gas
fired
turbines and combined cycles (CCs), the general economic and
environmental potential of cofiring in natural gas fired turbines and
CCs, the
economic and environmental potential of cofiring fuel gas in the RoCa3
power
plant of E.ON (supplier of electricity and heat at Rotterdam) and the
government's financial incentives for energy investments. Indirect gasification
with advanced fuel gas clean up has been identified as the most attractive
thermochemical conversion technology but still requires a significant
R&D
time. It is concluded that although cofiring in natural gas fired turbines
and
CCs has the potential to fulfil a significant part of the main goal
of the Dutch Renewable Energy Policy, CO2-reductioncosts are relatively
high compared
with cofiring in coal based plants and the contribution to the future
renewable
energy based energy supply system in the Netherlands is limited due
to the
restricted amount of low calorific gas that can be cofired in conventional
gas
turbines and CCs and their limited annual operating hours. By adjusting
the
turbine or CC this amount can be increased, however these adjustments
involve significant investment costs and will make possible sole operation
on
natural gas less evident.
