An transition is underway in most regions, predominantly power sector. This research highlights technical feasibility viability 100% renewable systems power, heat, transport desalination sectors. It presents technology-rich, multi-sectoral, multi-regional cost-optimal pathway for 145...
Abstract The global energy system has to be transformed towards high levels of sustainability in order comply with the COP21 agreement. Solar photovoltaic (PV) offers excellent characteristics play a major role this transition. key objective work is investigate PV transition based on respective scenarios and newly introduced model developed by authors. A progressive group present results fast growth installed capacities supply share solar total primary demand world decades come. These can...
Abstract Seawater reverse osmosis (SWRO) desalination is expected to play a pivotal role in helping secure future global water supply. While the reliance on SWRO plants for security increases, there no consensus how capital costs of will vary future. The aim this paper analyze past trends expenditures (capex) as historic cumulative online capacity based learning curve concept. capex found 4,237 that came from 1977 2015. A rate 15% determined, implying reduced by when was doubled. Based...
This work presents a pathway for Saudi Arabia to transition from the 2015 power structure 100% renewable energy-based system by 2050 and investigates benefits of integrating sector with growing desalination sector. can achieve energy 2040 while meeting increasing water demand through seawater reverse osmosis (SWRO) multiple effect distillation (MED) plants. The dominating sources are PV single-axis tracking wind plants 243 GW 83 GW, respectively. levelised cost electricity (LCOE) is 49 €/MWh...
Energy security analysis is a strong tool for policy makers. It allows them to formulate policies that would enhance energy systems by targeting necessary actions. In this study, the impacts of transitioning from fossil fuels renewables dominated system on analysed Jordan. A Best Policy Scenario was developed Jordanian trace transition 100% renewable system. future qualitative approach utilising colour codes. The results reveal primary demand increases 64 TWh in 2015 130 2050, electricity...
The aim of this research is to analyse the impact renewable energy (RE) technologies and sector coupling via analysing transition pathways towards a sustainable system in Chile. Four scenarios for power, heat, transport desalination sectors were assessed using LUT Energy System Transition model. current policy scenario was modelled compared with three best scenarios. results showed that 100 % renewable-based by 2050 technically feasible. Further, such an would be more cost-efficient than...
This is a discussion and response to "Global 100% energy transition by 2050: A fiction in developing economies?" authored Anthony Afful-Dadzie published Joule 5 (2021) 1634–1643. The preview has raised concerns around the feasibility of transitions towards renewable sustainable technologies economies, after examining article Bogdanov et al. (2021). Although, author rightly pointed out disparity recent growth across developed countries world, along with highlighting pertinent issue...
Abstract Afforestation is one of the most practised carbon dioxide removal methods but constrained by availability suitable land and sufficient water resources. In this research, existing concepts low-cost renewable electricity (RE) seawater desalination are built upon to identify global CO 2 sequestration potential if RE-powered plants were used irrigate forests on arid over period 2030–2100. Results indicate a cumulative 730 GtCO during period. Global average cost estimated be €457 per tCO...
The cost-optimal pathway for moving from the current fossil-fuel based energy system to 100% renewables is still an open question. This work presents first study that analyses transition towards a renewable under different spatial resolutions (1-node, 6-nodes electrically isolated and interconnected) various coupling configurations power, heat, transport desalination sectors. With LUT Energy System Transition Model case of Chile, 12 scenarios were investigated in hourly resolution...
Transitioning to 100% renewable energy mitigate climate change requires solutions for hard-to-abate sectors. It must also be complemented with negative emissions technologies ensure security. Previous studies have investigated the feasibility of e-fuels and e-chemicals production export some carbon dioxide removal in several regions. This study investigates, first time, techno-economic impacts offering such services on an exporting country’s system as it transitions by 2050. Egypt is used a...
This study analyses the role that renewable energy based desalination, in conjunction with improvements water use efficiency irrigation sector, can play towards securing future global supplies. It is found desalination demand by 2050 be reduced as much 30% and 60%, depending on growth rate. India, China, USA, Pakistan Iran account for between 56% 62% of demand. Decarbonising sector 2050, will result average levelised cost decreasing from about 2.4 €/m3 2015, considering unsubsidised fossil...
Under the Paris Climate Agreement, sustainable energy supply will largely be achieved through renewable energies. Each country have its own unique optimal pathway to transition a fully system. This study demonstrates two such pathways for Bolivia that are both technically feasible and cost-competitive scenario without proper targets, significantly more cost-efficient than current would driven by solar PV based electricity high electrification across all sectors. Simulations performed using...
Abstract Pakistan is currently undertaking a substantial expansion of electricity generation capacity to provide for all its end‐users and satisfy fast‐growing economy. Adoption low‐cost, abundant clean renewable energy will not only fulfil growing electricity, heat, transportation desalinated water demand but also help achieve the goals set under Paris Agreement. A technology‐rich system model applied in hourly resolution has been used investigating transition 5‐year periods until 2050....
Imported fuels used up to 50% of Sri Lanka's export income and contributed the recent crippling energy crisis. This study explores possibility using island's indigenous renewable resources secure supply for power, heat, transport desalination sectors by year 2050. The costs, CO2 emissions land use requirements system transition pathways are examined. An model in technology-rich, hourly multi-region resolution was applied. In an entirely renewables-based system, cumulative cost 2050 is...
In this paper, we present issues of electricity storage requirements based on comparative studies various results. It was found that when increase energy from VRE, the use and its capacity increases until reach some threshold. After threshold, starts to decline even if size. An optimally utilized about daily average demand would be sufficient grid penetration 90% total demands VRE. The understanding physics economics future system is mandatory build operate it optimally.
Resource complementarity carries significant benefit to the power grid due its smoothing effect on variable renewable resource output. In this paper, we analyse literature data understand role of wind-solar in future energy systems by evaluating impact penetration, corresponding curtailment, storage requirement and system reliability. Results show that significantly increases penetration compared stand-alone wind/solar without need storage. However, as capacity increases, capability increase...
