And Storage ◽

AbstractThis paper analyzed the current situation and development trends of energy consumption and carbon emissions, and the current situation and development trend of coal consumption in China. In the context of recently established carbon peak and carbon neutralization targets, this paper put forward the main problems associated with the green and low-carbon development and utilization of coal. Five key technological innovation directions in mining were proposed, including green coal development, intelligent and efficient mining, low-carbon utilization and conversion of coal, energy conservation and emission reduction, carbon capture, utilization and storage (CCUS). Focusing on the above technological innovation directions, it is suggested to carry out three basic theories, including the theory of green efficient intelligent mining, clean and low-carbon utilization and transformation of coal, and CCUS. Meanwhile, it is proposed to develop 12 key technologies, including green coal mining and ecological environment protection, efficient coal mining and intelligent mine construction, key technologies and equipment for efficient coal processing, underground coal gasification and mining, ultra-high parameter and ultra-supercritical power generation technology, intelligent and flexible coal-fired power generation technology, new power cycle coal-fired power generation technology, the development of coal-based special fuels, coal-based bulk and specialty chemicals, energy conservation and consumption reduction, large-scale and low-cost carbon capture, CO2 utilization and storage. Finally, necessary measures from the governmental perspective were also proposed.

This article describes how basing on the future behavior of microgrid system, forecasting renewable energy power generation, load and real-time electricity price, a model predictive control (MPC) strategy is proposed in this article to optimize microgrid operations, while meeting the time-varying requirements and operation constraints. Considering the problems of unit commitment, energy storage, economic dispatching, sale-purchase of electricity and load reduction schedule, the authors first model a microgrid system with a large number of constraints and variables to model the power generation technology and physical characteristics. Meanwhile the authors use a mixed logic dynamical framework to guarantee a reasonable behavior for grid interaction and storage and consider the influences of battery life and recession. Then for forecasting uncertainties in the microgrid, a feedback mechanism is introduced in MPC to solve the problem by using a receding horizon control. The objective of minimizing the operation costs is achieved by an MPC strategy for scheduling the behaviors of components in the microgrid. Finally, a comparative analysis has been carried out between the MPC and some traditional control methods. The MPC leads to a significant improvement in operating costs and on the computational burden. The economy and efficiency of the MPC are shown by the simulations.

The Future ◽

The future of Australia’s electricity industry has resulted in significant debate about the mix of electricity generating technologies. The Finkel Review and ensuing National Electricity Guarantee policy discussion have revealed divisions between key stakeholders over the future generating mix between renewable and fossil fuel power generation options. A portfolio of technologies will be required, including the need for gas-fired power generation with and without carbon capture and storage (CCS), to provide dispatchable synchronous electricity. Gas Vision 2050 has stated that CCS, along with biogas and hydrogen, will be one of the three transformational technologies affecting the gas industry going forward. Through the use of a techno-economic model, the costs for a hypothetical new-build gas-fired power plant in the Hunter Valley with and without CCS were estimated. The model is cross referenced with other authoritative publications including the CO2CRC Australian Power Generation Technology Report. The model considers the base-case scenario and sensitivity analysis of key cost drivers such as the domestic gas price and labour. The results of the model will enable key energy and gas industry stakeholders to make informed decisions about the vital role of gas as a power generation technology in Australia to deliver dispatchable synchronous electricity in a carbon constrained environment.

Policy Criterion ◽

The analytical hierarchical process (AHP) was adopted in this study to determine the priority of the policy criterion related to promoting wind energy, considering the environmental practitioners’ points of view. The results were described as follows. The practitioners from environmental organizations suggested that the most important major criteria are in the following order: policy criterion layer, technical criterion layer, economy criterion layer, and energy education criterion layer. For the global weights of the criteria, the criteria with top five weights were in the order as follows: “active development of green energy industry by government”, “supply and consumption method of low-carbon and low-pollution energy”, “increase of percentage of power generation from renewable energy in total power supply”, “encourage manufacturers to develop new wind power generation technology”, and “continually develop the technology projects which has potential and prospects in the future”.

Given a potential increase in low-carbon power generation, assessing the criticality of metals used for its technologies is of significant importance. While several studies analyzed the metal criticality of an individual technology, the national metal criticality for a wide range of low-carbon power generation technologies and the comparison of overall criticality of each technology have yet to be fully evaluated. Therefore, this study firstly evaluates the criticality of 29 metals used in facilities for renewable energy and highly efficient thermal power generation in Japan and then compares the overall criticality for each technology to identify metals that might impose limitations on these technologies and to discuss measures for removal of factors hindering the spread of low-carbon power generation technologies. It was discovered that solar power generation technology is the most critical technology from the perspective of supply risk due to the use of indium, cadmium and selenium, while wind power generation is the most critical technology from the perspective of vulnerability to supply restriction because of the use of neodymium and dysprosium. A developed approach would have a significant potential to contributing to energy-mineral nexus, which may assist in providing policy implications from the perspectives of both specific metals and technologies.
