Carbon dioxide removal (CDR) from the atmosphere is likely to be needed limit global warming 1.5 or 2°C and thereby for meeting Paris Agreement. There a debate which methods are most suitable cost-effective this goal thus deeper understanding of system effects related CDR effective governance these technologies. Bio-Energy with Capture Storage (BECCS) Direct Air (DACCS) two methods, that have d...

this paper is concerned with the estimation of total factor productivity (tfp) growth for the iranian electric utilities during the period 1980-1993 on the basis of panel data. a translog cost function is used which accommodates firm - specific variability through a one - way error component model. the results show that the iranian electricity supply industry experienced increasing returns to s...

In our previous work (Part I), we evaluated the thermodynamic models of biomass-fed integrated gasification solid oxide fuel cell system with a carbon capture and storage (BIGFC/CCS) unit. this II), techno-economic analysis proposed negative emission power plants is carried out. Levelized cost electricity, net present value (NPV), payback period, internal rate return (IRR), levelized (LCNC) are...

Recently perovskite/crystalline Si (cSi) tandem cells draw considerable attention because their high efficiency can reduce the levelized cost of electricity and increase power density photovoltaics (PVs) to accelerate energy transition. While theoretical limits for are well known, practical less clear. Herein, a new method is presented calculate four-terminal (4T) based on performance single-ju...

Expansion of telecommunication networks even to the most remote areas where connection to the utility grid could never be justified, especially in touristic regions, has led to the increasing need for stand-alone power systems. In Adriatic coastal area employment of hybrid photovoltaic-based systems is straightforward due to high sun potential. Inherent intermittent nature of renewable sources ...

Incorporating thermal energy storage (TES) into a concentrating solar power (CSP) system extends the power production hours, eliminating intermittency and reducing the Levelized Cost of the Energy (LCOE). The designed TES system was integrated with a 3 kW free-piston Stirling convertor. A NaF–NaCl eutectic salt was chosen as the phase change material (PCM) with a melting temperature of 680 ◦C. ...

We develop a novel hypothesis around the impact of related technology on development an experience curve. explore implications this in case wind energy, which has been historically developed onshore and is currently experiencing rapid growth deployment offshore. look at modelling offshore energy as (1) fully new technology, (2) direct offshoot wind, (3) hybrid. Focusing levelized cost electrici...

This paper describes and validates the HydroCalculator Tool developed by Conservation Strategy Fund. The HydroCalculator Tool allows researchers, policy-makers and citizens to easily assess hydropower feasibility, by calculating traditional financial indicators, such as the levelized cost of energy, as well as greenhouse gas emissions and the economic net present value including emissions costs...
