Technical and economic feasibility analysis of a subsea shuttle tanker for CO2 transport to the troll field

The Subsea Shuttle Tanker (SST) was presented by the authors as an innovative and cost-effective solution in several research works. This new approach offers a viable alternative to subsea pipelines and shuttle tanker ships for transporting liquid CO2 from onshore facilities to marginal offshore reservoirs. A previous technical–economic feasibility study found that the SST is generally economically competitive to the subsea pipelines and shuttle tanker ships for distances below 180 km and CO2 transport volumes of one million tons per annum (mtpa). The economic cost models are based on those developed in Maritime UN-manned Navigation through Intelligence in Network (MUNIN) D 9.3 and the Zero Emission Platform (ZEP) projects. This paper will take this previous study further by focusing on performing the technical and economic feasibility analysis for operation in the Troll field on the Norwegian continental shelf (NCS), which has a transport distance of 65 km and a CO2 volume of 1.5 mtpa. Two SST design solutions are investigated by downscaling and upscaling the reference baseline design to evaluate SST’s technical feasibility. Using the abovementioned cost models, the CO2 transportation cost per ton using SST is compared with subsea pipelines and tanker ships. The numerical results show that it is economically feasible to manufacture SST with cargo capacities of 4453 m3 and 2203 m3. Furthermore, the results show that the SST is the most cost-effective option for transporting low-volume CO2 (1.5 mtpa) over short distances.

Economic Feasibility Study of Deploying Green H2 Infrastructure at Los Angeles International Airport (LAX)

Air transportation is among the critically debated subjects, contributing to approximately 2.5% of global CO2 emissions 1. The main strategy for addressing environmental concerns related to aviation emissions is the shift to low-carbon propulsion technologies for aircraft. Hydrogen could be introduced to the aviation sector as a fuel for fuel cell-powered aircraft or for direct combustion jet engines, with anticipated zero- to low-carbon emissions 2. Moreover, the universe lightest element possesses a very high gravimetric energy density of 120 MJ/kg, which will be higher when stored in cryogenic hydrogen form3, making it an ideal alternative to conventional aviation fuels (for example, jet fuel). This study provides a techno-economic analysis of introducing green hydrogen infrastructure to Los Angeles International Airport (LAX) to promote its transition towards sustainability. Preliminary research showed that the largest uncertainty in economic projections for H2-powered aviation hinges on future H2 supply costs, rather than aircraft modifications4. Therefore, the costs of potential hydrogen implementation routes, including off-site production supplied by road tankers or pipelines to the airport, and on-site production, will be assessed. In summary, the implementation of a hydrogen infrastructure at LAX is not only an initiative to reduce its associated carbon footprint but also suggests a practical and environmentally sustainable paradigm for future upgrades to aviation fuel infrastructure.

Technical & Economic Feasibility Study of Proposed Pump Storage Power Plants at Kuda Oya, Mul Oya, Gurugal Oya, and Dambagasthalawa

This paper presents a Technical and Economic Feasibility Study of proposed Pumped Storage Power Plants (PSPPs) at KM (Kuda Oya, Mul Oya), KMG (Kuda Oya, Mul Oya, Gurugal Oya), KG (Kuda Oya, Gurugal Oya), and Dambagasthalawa. Sri Lanka aims to transition away from a coal-dominant electricity sector within the next decade, aligning with sustainability goals outlined by the United Nations. In pursuit of affordable and clean energy sustainability, the Sri Lankan government has opted to shift its long-term energy policy towards renewable sources, departing from fossil fuels. Despite this shift, a significant portion of Sri Lanka's electricity consumption—approximately 600 MW from oil and 900 MW from coal—persists. The country now aims to source 80% of its energy from renewable sources, necessitating a focus on underutilized opportunities. In selecting the best candidate sites for Pumped Storage Power Plant (PSPP) design, comprehensive hydrological and sedimentation studies play a pivotal role. In this endeavor, we endeavor to re-rank the selected candidate sites for pumped storage power plants considering technical & financial feasibility by conducting comprehensive hydrological and sedimentation studies. These studies are pivotal for assessing the feasibility and long-term viability of potential sites, aiming to select the most sustainable candidate site in every aspect. Therefore, the primary objective of this research is to conduct a thorough hydrologic study of the proposed KMG and Dambagastalawa pump storage power plants, focusing on identifying potential energy-saving opportunities in pumping when these plants operate as open-loop systems. This study will analyze the hydrology of the upper ponds of the Kuda Oya, Mul Oya, and Gurugal Oya (KMG) pump storage power plants, and the Dambagastalawa Oya pump storage power plant, assessing the potential reduction in pumping energy. Such insights are essential for optimizing the design and operation of PSPPs to ensure economic viability and sustainable energy generation. Furthermore, this research addresses the importance of studying sedimentation in both the upper and lower ponds of the KMG and Dambagastalawa pump storage power plants. Sedimentation calculations will be performed to determine reservoir lifetimes, offering critical insights into the long-term feasibility and maintenance requirements of these projects. The findings of this study are expected to provide valuable guidance to policymakers, investors, and PSPP designers in selecting the most suitable sites for addressing Sri Lanka's peak power demands and urgent electricity needs. By emphasizing the significance of hydrological and sedimentation studies, this research underscores the importance of thorough site assessment in optimizing the design and operation of Pumped Storage Power Plants.

Energy Storage Solutions to De-Carbonize the Electric Supply in Jordan

This paper aims to estimate the size of Energy Storage Systems (ESS) required de-carbonizing the electrical network in Jordan. Load profile in addition to the PV and Wind energy profiles were studied and used as input data to the simulation model. Different cases of RE penetration levels as a percentage of load demand were considered and entered to the simulation model as well. Other factors, such as allowed over-generation and ESS efficiency also provided and calculations carried out accordingly. In addition to the technical consideration, an economic analysis approach added to the study. Results show that staying with the current level of RE penetrations, i.e. at PV 11% and W 9% (RE level 20% of load demand) and 5% curtailment, no need to install ESS to absorb the RE intermittency and variability. As RE penetration level increases, the need for ESS becomes necessary, i.e. to reach 100% RE penetration and de-carbonize the electrical network accordingly, an ESS of 138,900.00MWH/ 7,386.57MW PHES would be required at PV 65% and Wind 35% penetration level and 25% curtailment with initial CAPEX investment of JOD 15,367,314,444.10. Economic feasibility study shows that with the current RE energy prices and ESS CAPEX, reaching the 100% RE penetration level would not be the optimum solution as there will be a negative cost impact, unless these prices reduced to a certain level making the solution feasible.

Optimising the Economic Feasibility of High-Speed Maglev Systems: A Simulation-Based Approach for Variable and Parameter Analysis

This study introduces an advanced software platform and process for the quantitative national economic evaluation of high-speed maglev systems, overcoming limitations of traditional methods through parameter variation experiments and automated solution search. Utilising the adapted German standardised evaluation, this research demonstrates how integrated modelling, evaluation and optimisation software can deeply analyse the impact of various variables and parameters on economic outcomes. By employing an optimisation algorithm, the software not only determines critical evaluation parameters to ensure benefits exceed costs but also deduces optimised model variables. The macroeconomic benefit-cost ratio guides the optimal design concept, with the research finding a critical value for ensuring economic feasibility. The proposed solution achieves a 22% improvement in this ratio (1.106 vs. 0.909) compared to the existing Hefei-Wuhu route, highlighting its potential for large-scale maglev implementation. Future development directions include integration with micro-simulation systems, support for random behaviour, sensitivity analysis, data-driven machine learning and enhanced user interface design for broader applicability.

Underpinnings of reservoir and techno-economic analysis for Himalayan and Son-Narmada-Tapti geothermal sites of India

The high capital cost and risks associated with the extraction process of geothermal energy are key factors in the project economics. This paper presents a comprehensive technoeconomic study based on reservoir heat and flow simulations along with the levelized cost of energy (LCOE) for two geothermal sites (Himalayan and Son-Narmada-Tapti i.e. SONATA) in India.Dual porosity reservoir simulation models were constructed and were used to obtain the cumulative and the dynamic thermal energy potentials of these sites. The simulation studies suggest that both sites are equally potent for geothermal energy extraction. Comparatively, the proven cumulative energy potentials for the Himalayan and SONATA sites are found to be 4.92–5.10 and 3.62–3.7 TW h, respectively, for the 30 years of production at a rate of 92 kg/s. This difference can be attributed mainly to higher temperatures and deeper sites at the Himalayan Province. Sensitivity analyses were conducted to assess the impact of various parameters, including porosity, permeability, fracture spacing, and thermal conductivity. The results suggest that porosity and permeability are the key enablers of efficient energy production. The economic feasibility study suggests that the LCOE costs are high for these sites ($148/MWh for the Himalayan and $137/MWh for the SONATA). These two sites have CO2 mitigation potential in the range of 3.12 and 11.36 Megatons from a single doublet well configuration considering the CO2 emissions from conventional coal-fired thermal power plants. Overall, SONATA can be the better prospect considering the logistics and operational challenges along with reservoir heat potential.

Techno-economic analysis of arsenic (III) removal using spiral wound polyethersulfone nanofiltration membrane at pilot scale

In this work, the influence of initial solution pH on membrane performance was carried out for arsenic (III) removal using spiral wound polyethersulfone (HFN300) Nanofiltration membrane at pilot scale. The rejection percentage was found to increase from 49 % to 96 % while increasing initial solution pH from 4 to 10. Speciation of arsenic, solute-membrane affinity, electric-migration effect along with convection and diffusion were found to be dominant mechanisms for arsenic removal. Donnan Steric Pore Model was selected to estimate the membrane parameters including pore radius (0.313 nm), membrane thickness (2.17 μm), and membrane charge density (−3.56 mol/m3).Excellent agreements were found between the experimental and simulated values for all the studied pH range. Selected model works satisfactorily within 10 % of error for both rejection percentage and permeate flow. Economic feasibility study was carried out for the rural population (India) and total annualized cost was found to be USD 0.90/m3 that seems both reasonable and affordable for arsenic free drinking water. It can be concluded that annualized production cost was dependent on membrane lifespan, electricity tariff, per capita, population size, arsenic feed concentration, etc. The result obtained in the study suggests the feasibility of using the NF process in removing arsenic from contaminated water. Overall, the study provides valuable insights into the mechanisms governing arsenic (III) removal through nanofiltration process using spiral wound polyethersulfone nanofiltration membrane at pilot scale, demonstrating the effectiveness of pH optimization and membrane modelling in improving removal efficiency, which can contribute to the development of cost-effective solutions for safe drinking water in arsenic-affected rural areas.

Economic Feasibility Study For The Setting Up And Utilization Of A Multipurpose Food Irradiation Facility In Jigawa State, North-West Nigeria

One proven and efficient method for processing and preserving food is food irradiation. Irradiation is a productive and economical technique that has several advantages over other technologies used in food processing. The technique helps prevent food loss and ensure food safety by getting rid of parasites and bacteria that can make people sick or even kill them. Produce from agriculture and animal food products can benefit from radiation treatment to increase shelf life while maintaining microbiological safety and quality. Based on more than 50 years of research and testing data, a number of national and international food and health organizations have acknowledged and supported the safety of food and products treated to ionizing radiation. The purpose of this study was to evaluate the economic feasibility for the establishment and utilization of a multipurpose food irradiation facility in Jigawa state and its environ as a post-harvest treatment for major arable crops cultivated in the state and its environ which include millet, sorghum, groundnut, sesame, rice, maize, tomatoes, pepper, onions, wheat, and dried fish. The study explored ways in which irradiation may be employed for each crops and vegetable with the approved dose rate. The cost of irradiation was also calculated for different sources of colbalt-60. The study results indicate one or more technically economically feasible application points for irradiation in the processing of each commodity considered. The most promising points are the potential for disinfestation of large quantity of crops and vegetables which will ensure food availability all year round and at a cheap rate for citizens as well as the potential for export thereby helping to grow the revenue and GDP of the state.

On the role of building use and operational strategy in integrating ice storage systems: an economic perspective

Ice thermal energy storage has been widely used in different types of building to manage cooling peak loads. In the present study, technical and economic feasibility studies have been performed to evaluate the effect of building use and storage strategy on integrating ice storage. Four different building uses, namely residential, office, educational, and commercial; and nine storage strategies are investigated. For each building type and storage strategy, the hourly cooling load is simulated for a typical day in each month. The appropriate cooling system is then selected and analyzed in terms of energy consumption. The additional capital required to install ice storage and the potential savings obtained by shifting the cooling load from peak to off-peak hours using this installation are estimated to assess the economic feasibility of integrating the storage system. The results show that although the energy consumption in systems with ice storage is generally higher than that in a conventional system, the annual energy costs can be up to about 50 % lower with appropriate storage strategies, albeit at the expense of a higher initial investment. It is also shown that building use and storage strategy significantly impact the economic feasibility of integrating ice storage into building cooling systems. Comparing four building types, the use of an ice storage system in residential buildings is much less economical due to the presence of 24-h cooling loads, so the payback period assuming an electricity tariff of 20¢ and considering the best storage strategy is more than 7 years, which is 62, 66 and 73 months more than the payback period for the office, commercial and educational buildings, respectively. Therefore, implementing different policies for residential and non-residential buildings is recommended to encourage the use of cold storage systems in the building sector.

Implementation of pumped hydro/photovoltaic systems in mining-degraded areas: a case study in Quadrilátero Ferrífero, Minas Gerais, Brazil

This work presents a proposal for the transformation of mining-degraded areas into renewable energy installations, converting deactivated mine pits, in the Quadrilátero Ferrífero (QF) region in state of Minas Gerais (MG), Brazil, into reservoirs for Pumped Storage Hydropower (PSH). Additionally, it proposes the alteration of adjacent areas impacted by mining extraction process, through their conversion into Photovoltaic Power Plants (PV). This measure has the potential to turn mining liabilities into sources of energy with lower environmental impact and sustainability for society. This process allows energy to be stored in the form of hydraulic batteries, which can mitigate the effects of intermittency of photovoltaic generation in the electrical grid. The presented methodology involves mapping deactivated mines, calculating the energy potential of the coupled PSH and PV systems, and conducting an economic feasibility study for PSH implementation. The work includes a case study discussing potential local environmental impacts and the energy potentials of this solution. The case study resulted in identifying a suitable pair of mine pits for a PSH in the QF, capable of supplying the electrical grid with approximately 234.3 MW, with the generated energy cost ranging between U$112.26/MWh to U$167.22/MWh. It is concluded that utilizing inactive mines as PSH reservoirs and installing PV in adjacent mining-degraded areas are innovative and technologically feasible strategies. Economically, their implementation will depend on the market price of energy.

Energy consumption and adverse environmental impacts have increased because of urbanization and intense construction following industrialization. Increasing the number of buildings with green building certification is important and necessary to reduce the negative effects of the construction sector on the environment. One of the significant factors in green building certification scoring systems is the utilization rate of renewable energy sources to meet the building’s energy needs. The generally high costs associated with renewable energy investments often emerge as a restrictive factor, especially in public buildings with limited budgets. It is crucial to utilize project support related to financing to meet the required funding. Conducting a proper feasibility study within the scope of the project application serves as a convincing factor in the project evaluation process and increases the likelihood of project acceptance. This study presents a detailed technical and economic feasibility study conducted for the solar carport planned to be installed as part of the Public and Municipal Renewable Energy Project (KAYEP) carried out by Kocaeli University (KOÜ) Uzunçiftlik Nuh Çimento Vocational School as a step toward becoming a green building. The design and analysis were conducted using PV*SOL software. According to the results of the study, it is projected that the planned 49 kWp photovoltaic (PV) system will generate approximately 55 MWh of electricity annually, resulting in a total income or savings of 183,967₺. It is expected to reduce annual energy costs by 99% and prevent the annual emission of 25,844 kg of CO2 into the environment.
