Perspectives Of Pre-Combustion Ccs Systems For Central Europe, Monika Vitvarova, Vaclav Novotny Apr 2016

Perspectives Of Pre-Combustion Ccs Systems For Central Europe, Monika Vitvarova, Vaclav Novotny

CO2 Summit II: Technologies and Opportunities

Carbon Capture and Storage (CCS) has a potential to play a significant role in the future of power generation in Europe, at least in a short to intermediate term. Among the reasons are necessity and also growing political willingness to limit the CO2 emissions while it appears that fossil fuels are to remain an important source for fuel and electricity production. CCS technologies however mean inevitable technical, energy and economic penalty, especially since most common fossil fuel for power generation in the Central Europe is lignite.

We are presenting the focus and first results of a recently initiated Norway Grants …


Minimizing The Energy And Economic Penalty Of Ccs Power Plants Through Waste Heat Recovery Systems, Vaclav Novotny, Monika Vitvarova, Michal Kolovratnik, Zdenek Hrdina Apr 2016

Minimizing The Energy And Economic Penalty Of Ccs Power Plants Through Waste Heat Recovery Systems, Vaclav Novotny, Monika Vitvarova, Michal Kolovratnik, Zdenek Hrdina

CO2 Summit II: Technologies and Opportunities

Implementation of currently considered and available CCS technologies into fossil power plants brings inevitable technical, energy and economic penalty. This is getting even larger when fossil fuels such as low rank coal are being utilized. All three generally considered CCS technologies were modelled – oxyfuel combustion and ammonia based post-combustion (subcritical power plant with fuel drying) and pre-combustion (IGCC with Rectisol method for CO2 separation).

After traditional methods of system optimization there was considered another way for increasing system efficiency. CCS technologies produce waste heat streams, which can be converted to electricity by small modular units with unit cost comparable …
