This work presents the modeling and thermodynamic analysis of two novel small-scale polygeneration systems that are capable simultaneously converting residual biomass to methanol (MeOH), electricity, heat a CO2-rich stream for agricultural greenhouses. The first system is based on downdraft gasifier, while second relies dual fluidized bed (DFB) gasifier. Both configurations leverage H2, O2, ele...

In order to keep the +1.5 °C over-temperature, previously predicted with high confidence by IPPC Sixth Assessment, as minimal feasible, it is more than vital achieve a low-emission energy system. Polygeneration systems based on thermochemical processes involve biomass conversion in multi-output of bioenergy carriers and chemicals. Due reduced input input/output diversification, polygeneration a...

Schemes of polygeneration plants based on carbon dioxide are presented, in which the energy source secondary resources and a gas turbine plant. These schemes make it possible to simultaneously produce electricity, heat, cold, liquid gaseous aggregate state, as well dispose part emitted into atmosphere, due its absorption from combustion products use for commercial technological purposes. The st...

To meet the CO2 reduction targets and ensure sustainable energy supply, the development and deployment of cost-competitive innovative low-carbon energy technologies is essential. To design and evaluate the competitiveness of such complex integrated energy conversion systems, a systematic thermo-environomic optimisation strategy for the consistent modelling, comparison and optimisation of fuel d...

In the present context of energy transition towards a carbon neutral society, residential sector plays an important role to combat climate change since it represents about 40% global final consumption and 30% direct CO2 emissions in European Union. Polygeneration systems, facilitating integration renewable energies, are feasible alternative enabling efficient use natural resources with low envi...
