“…Based on calculations by (Antony et al, 2017), who calculated the levelized cost of hydrogen production using nuclear reactors, capital costs are the largest component at 71% including debt as component. O&M costs constitute 28.9% of the overall cost, while decommissioning cost stands is at 2.85% and front end and back end fuel cycle cost at 2.5%.…”

Industrialization on renewable energy is needed to begin to avoid dependence on fossil fuels. West Nusa Tenggara (NTB) Province has the potential for the development of bioethanol which is integrated with the Small Modular Reactor (SMR) nuclear reactor. Through this study, the economics of sugar- ethanol plant and SMR reactors was calculated, as well as development schemes supported by policy recommendations will be presented. This study uses cash flow modelling from a sugar-ethanol plant and SMR to determine the economics of the project. The potential site is mapped by using scoring method to obtain the best location. The SMR reactor can operate with Internal Rate of Return (IRR) of 9%, Net Present Value (NPV) USD 2,325,347,181, and payback period 13 years. The sugar-ethanol plant has IRR of 12.6%, NPV 441,278,716, and payback period of 10 years. The appropriate locations for the construction of the SMR reactor are in Bima and Dompu districts, based on mapping analysis both locations have potential for future development.

“…It is the case because all annual revenues with a weighted average value S w ave are accumulated in the range of years 0, τ expl -Figure 3-and therefore, in Formula ( 14), the factor 1 − e −rτ expl discounting revenues S w ave backwards for the moment 0 reaches its top level. In practice, the annual revenues of S are randomly distributed in years 0, T -Figure 1-while profit NPV from the use of RES, as already mentioned above, takes the value intermediate between profits NPV min and NPV max (see Formulas (19) and ( 23)). After substituting Equations ( 8) and (9) to Formula (18), and after performing the integration operation, the following is obtained:…”

“…The first one uses discrete notation by means of geometric series to evaluate economic efficiency, since the discount calculus is essentially a geometric progression. Currently, in many works we can see the predominance of this direction of research [13][14][15][16][17][18][19]. However, these models require complicated and sometimes tedious calculations or sophisticated optimization algorithms, making certain assumptions which simplify the model and thus give only approximate or uncertain results.…”

Due to the constant trend of building wind turbine sets and photovoltaic cells, the so-called renewable energy sources, it is important to develop a mathematical model that will allow us to analyse the economic viability of their operation. By using this model, multivariate calculations should be carried out and developed in the form of universal nomograms that will allow us to estimate this viability almost on an immediate basis. In this paper, such a model for the unit cost of electricity production from renewable energy sources is presented. It is based on a continuous-time Net Present Value notation. The multi-variant calculations performed with it take into account different subsidy levels and operating time of the renewable energy sources. The paper presents values of unit costs of electricity production from renewable energy sources and values of maximum subsidies for this production. It turns out that subsidies are necessary for renewable energy sources to exist on the energy market. An additional disadvantage is the fact that renewable energy sources are not able to provide a stable electricity supply throughout the year.

“…In Reference [4], a possibility and assessment of thermodynamic efficiency for NPP expansion is considered using, among other things, production of thermochemical hydrogen for its further commercial utilization. In Reference [5], an assessment is made of the technical and economic competitiveness of hydrogen production at NPPs for the transport needs based on alkaline electrolysis and boiling water reactor, and in Reference [6], an approach is proposed relating the use of hydrogen in the production of additional electricity at NPPs with pressurized water reactor. It is noted that approaches focused on upgrading flexibility of low power NPPs 7,8 and using hydrogen technologies for power generation systems at cogeneration stations gain recognition among scientific community 9,10 …”

The paper presents the new results of experimental and theoretical studies of combustion processes in hydrogen-oxygen mixtures. Considered the impact of pressure in the combustion chamber on the efficiency of hydrogen fuel combustion. Experimental research results showed that the hydrogen content on the exit from the first and second sections of the experimental combustion chamber was 5.674% mass and 0.719% mass, respectively, at the pressure of 1.0 MPa. The proposed pressure range extension is based on computational experiments relating mathematical modeling of the processes occurring in the experimental setup, in particular, for the pressure in the combustion chamber and flame tube ranging from 0.25 to 6.0 MPa. The obtained results were verified. The accuracy in estimating the temperature of combustion products found due to the computational and physical experiments is in the range of 98.89%-102.37% at the outlet of the first section, and is in the range of 97.38%-97.86% at the outlet of the second section. Meanwhile, the accuracy in estimating the hydrogen underburning is in the range of 100.37%-101.53% at the outlet of the first section, and is in the range of 98.81%-99.05% at the outlet from the second section. Computational experiments show that an increase in the combustion products pressure leads to an increase in the combustion products temperature at the exit from the first section was within 1264 C-1713 C range, and on the exit from the second section was within 937 C-1386 C. It is shown that the recombination rate achieved in the experimental setup and computational experiments was 10.718 to 10.814 kg/(kgÁs) at the pressure from 0.25 to 6.0 MPa. In this case, the minimum time necessary to complete recombination of combustion products was 0.5478 to 0.55 s under given conditions of external cooling. The pressure range in the combustion chamber does not significantly affect the mass fraction unreacted hydrogen.
