Clean hydrocarbon technologies have a key role to play in achieving the circular carbon economy while meeting climate targets in many countries around the world. The aim of this work is to assess which technology, or combination of technologies, is the most cost-effective in achieving climate targets by 2030 leading to a quick and smooth transition to a low carbon energy system in Saudi Arabia and similar oil-based economies. We find that low carbon policy support by banning crude oil in power generation, leads to accelerated underground oil gasification, in the absence of carbon prices. We also find that setting a policy for carbon reduction targets leads to a more flexible energy system transition enabling more technologies in the mix with an increasing transition period. Our results also show that clean hydrocarbon technologies may be sufficient to achieve new climate targets, as shown by the stabilised emissions in scenario 3 by 2025, without the implementation of renewable sources of energy which most studies do not include. We propose that by investing in clean hydrocarbon technologies over the short term, the transition towards a low carbon economy will be accelerated while developing renewable sources of energy over the long term.

The deployment of renewable energy technologies will play a crucial role in the global transition to a low-carbon economy and ultimately in the fight against global warming. However, this transition could face important problems because most of those technologies rely on the steady supply of critical minerals. Colombia, thanks to its hydrological resources, has relied on the hydro­power for electricity generation. However, the government has implemented measures to back-up the energy system in draught periods and, consequently, fossil fuels-based plants have increased the market share and with these, CO2 emissions. This study assesses the mineral demand in Colombia in the period 2020-2050 for the rare earth elements embedded in the deployment of wind power technologies in four different climate policy scenarios in order to establish whether they could face geological bott­lenecks that could ultimately hamper the transition to a low-carbon economy. The Gigawatts (GW) of future capacity additions in the energy system are converted into tons of metal using published metal intensities of use and assumptions of Colombia’s technological pathway. Then, the cumulated mineral demand is compared against current mining production rates and geological reserves to establish geological bottlenecks. The results show that the reserves will not pose any threat to its transition. However, when compared to current mining rates, the mineral demand in 2050 could pose a problem for the supply of minerals. Finally, this study gives some policy recommendations that could be used to mitigate these issues, such as substitution, improved circular economy and sound technological choices.

The article discusses issues related to the transition of the oil and gas industry to a low-carbon economy. Within the framework of the scenario approach the key risks of the transition period are considered. The importance of managing climate risks for organizations in the oil and gas industry is emphasized. The prospect of including climatic risks in the general risk management system of the organization is shown. Examples of the implementation of new approaches to climate risk management and adaptation to climate change in Russia and abroad are given.

This book is written by a retired grid engineer and deals with renewable sources of energy and the instability of the electrical distribution grid. Derek Birkett carefully goes through the arguments about the electrical supply and the effect of intermittent and variable renewable sources of energy on grid stability. As a result of investment in renewable energy and the increasing costs of carbon taxes levied on fossil fuel fired generation, the government has created a situation which is very expensive for consumers and industry, and is unsustainable. The government has intervened in the energy market and provided subsidies and policy support for renewable energy without considering the consequences for the stability of the electrical grid system. The government has no strategic vision of the future for energy generation and no expertise to draw upon. Consumers experience increasing energy costs, power outages and blackouts which will be costly and hard to recover from. Derek states quite clearly that “… the state should no longer use environmental regulation for political purposes unless there is a clear imperative for national well-being and security.”

Energy Share

The paper considers modeling the efficiency of power system with integration large share of variable renewable sources of energy with the account of climate conditions of Ukraine. The proposed methodology with its position between system planning and dispatch simulation contributes to the field of hybrid energy system models. The idea behind the method allows high spatial and temporal resolution as well as the inclusion of the technical details of the power system and its dispatch. The novelty of this method is the usage of a parametric approach is chosen to analyze different variable renewable sources of energy scenarios, precisely every possible its share and mix. This provides insights on the systematic effects of different resource mixes and may serve as a new approach to the analysis of future power system development. The additional novelty aspect allows the optimization of the design of the technical details of the power system with large variable renewable sources shares to have continuous improvement of its energy efficiency. The energy balance model generator is well suited for the analysis of large share of variable renewable sources integration in the power system. The design of technical details of the power system with large variable renewable sources shares was optimized with the energy balance model. The results of numerical modelling demonstrated that at 80% variable renewable sources of energy share, the overproduction is reduced to 20%, down from over 100 % without grid extensions. With it, the necessary wind and solar capacity decreases. Consequently, the possible achievable variable renewable sources of energy share is increased, assuming the same technical potential. According to the results, a Ukrainian grid would allow to increase the possible variable renewable sources of energy share from 50% to 75%.

Hybrid Renewable Energy System

Background: Renewable sources of energy have emerged as a promising eco-friendly alternative to the conventional and non-renewable sources of energy. However, highly variable and intermittent nature of renewable sources acts as a big hurdle in their widespread adoption. Hybrid energy systems provide an efficient and reliable solution to this issue, especially for the non-grid connected or stand-alone systems. Objective: The study deals with the design and optimization of a stand-alone hybrid renewable energy system. Methods: Two different configurations consisting of PV/W/B/DG have been modeled and optimized for lower annualized cost using cuckoo search, a meta-heuristic algorithm. Analysis of these system configurations has been carried to meet the energy demand at the least annualized cost. Results and Conclusion: Using a real world data for an existing educational organization in India, it is proven that the proposed optimization method meets all the requirements of the system and PV/B/DG configuration returns a lower annualized cost as well as leads to lower emissions.

Hybrid Renewable Energy

The diffusion of renewable sources of energy has been increased because they reduce the environmental influence and meet the increase in demand of energy. The key feature of the renewable source of energy is their changeability and irregularity. These draw backs are overcome by combining the non-conventional sources through storage and back up. However the incorporation of renewable sources of energy makes the system more complex in respect of energy sharing, control and analysis. The main objectives of energy management configuration are to ensure the maximum exploitation of renewable sources, continues power supply to the load, lessen the rate of energy production and increase the steadiness of the system. To accomplish these purposes efficient and fast control techniques are required which are proficient of handling information perceptively and captivating acute decisions vigorously inside the operative limitations. This paper presents an explicit review of energy management approaches currently existing and those now in research for the smooth process of hybrid system with renewable sources.
