This paper evaluates the economic feasibility of an integrated production pathway combining fast pyrolysis and bio-oil gasification. The conversion process is simulated with Aspen Plus® for a 2000 metric ton per day facility. Techno-economic analysis of this integrated pathway has been conducted. A total capital investment of $510 million has been estimated and the minimum fuel selling price (M...

In this work, the hierarchical decomposition methodology was used to conceptually design the production of fuel ethanol from sugarcane. The decomposition of the process into six levels of analysis was carried out. Several options of technological configurations were assessed in each level considering economic and environmental criteria. The most promising alternatives were chosen rejecting the ...

Small modular nuclear reactors (SMRs) represent a robust opportunity to develop low-carbon and reliable power with the potential meet cost parity conventional systems. This study presents detailed, bottom-up economic evaluation of 12 × 77 MWe (924 total) light-water SMR (LW-SMR) plant, 4 262 (1,048 MWe) gas-cooled (GC-SMR) 5 200 (1,000 molten salt (MS-SMR) plant. Cost estimates are derived from...

This paper presents a techno-economic optimization model to analyze the economic viability of photovoltaic battery (PVB) system for different residential customer groups in Switzerland clustered based on their annual electricity consumption, rooftop size, irradiation and location. The simulations static investment are carried out years 2020–2050 comprehensive sensitivity analysis is conducted i...

Hydrogen production through electrolysis from renewable sources is expected to play an important role achieve the reduction targets of carbon dioxide emissions set for next decades. Electrolysers can use energy surplus produce green hydrogen and contribute making electrical grid more stable. be used as medium-long term storage, converted into other fuels, or feedstock in industry thus contribut...

Techno-economics involves the systematic evaluation of economic aspects to provide solutions technical problems encountered. The study techno-economic analysis can a basis for decision-making related factors. This was analyze scope research on education using bibliometric and data mapping approach (i.e., VOSviewer software). Material gathered from application reference manager databases. materi...

Seasonal thermal energy storage (STES) holds great promise for storing summer heat winter use. It allows renewable resources to meet the seasonal demand without resorting fossil-based back up. This paper presents a techno-economic literature review of STES. Six STES technologies are reviewed and an overview representative projects is provided. The key project parameters operation performances, ...
