Levelized Cost of Fuel (LCOF) studies for microreactors using TRISO fuel in hydride and beryllium-based composite moderators in open and closed fuel cycles
… moderators can reduce overall fuel-cycle costs by up to about 20% relative to graphite, whereas beryllium-based moderators may remain 40–50% costlier due to higher raw material expenses. Shifting from prismatic blocks to pebble beds decreases moderator usage and increases burnup, thus …

Feasibility and technoeconomic analysis of small-scale biomass to power system with novel producer gas cleanup technology
… at 22kWe. This corresponds to a capital cost of $9,600, which is 34% of the retail price of current similar systems. This results in a levelized cost of energy range of $0.07 per kWh to $0.34 per kWh depending on the cost of biomass feedstock. This range is large for a levelized cost of …

Time-variant solar-powered electrodialysis reversal desalination for affordable off-grid clean water supply
… systems cannot be installed, at no environmental cost. However, the levelized cost of water achieved by state-of-the-art PV-EDR systems is still prohibitively high for cost-constrained communities, due to the large battery capacity required to reshape the solar power profile and accommodate the …

Technoeconomic Assessment of Carbon Dioxide Conversion Projects in a Canadian Context
… in simulation result in high variability for cost and emissions. For example, the levelized cost of production for methanol from CO2 ranged from $645 to $1775 USD/ton (2020) when harmonized, with an emissions range of -1.01 to 1.89 tCO2e/t product. Harmonization resulted in an average increase …

Investigations on Solar Powered Direct Contact Membrane Distillation
… an ideal solution for DCMD applications. A levelized cost analysis is presented for a waveguide powered DCMD plant of a 30,000 capacity. A combination of waveguide and DCMD shows levelized cost of water at $1.80/m³, which is found to be lower than previously reported solar desalination water …

Irradiation effects on mechanical and physical properties of SS304L-nanotube composites
… small amounts of CO2 emissions.[2] The levelized cost of electricity generated by nuclear power plants is dominated by the capital cost of the structural components,[3] therefore extending the operating lifetime of these plants is of high economic and environmental interests. However, …

An Evaluation of The Performance and Comparative Cost of Ground-mounted and Rooftop Mounted Solar Photovoltaic Systems
… interest to be abandoned, largely due to the cost required to replace a building's asbestos roof. An alternative solution to replacing an asbestos roof is to install a ground-mounted photovoltaic system, which is more costly compared to a rooftop mounted system. This study aims to determine if …

Cost-Risk Analysis of the ERCOT Region Using Modern Portfolio Theory
… we study the use of modern portfolio theory in a cost-risk analysis of the Electric Reliability Council of Texas (ERCOT). Based upon the risk-return concepts of modern portfolio theory, we develop an n-asset minimization problem to create a risk-cost frontier of portfolios of technologies within …

A machine learning approach to evaluating renewable energy technology : an alternative LACE study on solar photo-voltaic (PV)
… technologies are often evaluated using the Levelized cost of electricity (LCOE), which is a measure of building and operating a generating plant over an assumed αnancial life and duty cycle. Naturally, instead of only measuring the cost, a more holistic approach would be to also assess the …

Synergistic design of a combined floating wind turbine - wave energy converter
… (FWT) may produce offshore renewable energy cost savings. Attaching the WEC to the FWT greatly reduces the WEC's steel frame, mooring lines, electric transmission lines, and siting/permitting costs, which may comprise 56% of a standalone WEC's cost. A 5 MW FWT currently requires up to 1700 …
