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.

Solar Thermal Power Generation

China is a big consumer of energy resources. With the gradual decrease of non-renewable resources such as oil and coal, it is very important to adopt renewable energy for economic development. As a kind of abundant renewable energy, solar power has been widely used. This paper introduces the development status of solar power generation technology, mainly introduces solar photovoltaic power generation technology, briefly describes the principle of solar photovoltaic power generation, and compares and analyzes four kinds of solar photovoltaic power generation technology, among which photovoltaic power generation technology is the most mature solar photovoltaic power utilization technology at present.

Over the years, several means of electrical power generation have been in place ranging from wood, coal, to fuel. All these means have at its point served purpose at the needed time. This work presents the historical research of solar power in space, an insight into some literature pertaining to Solar Power Satellite (SPS) and Wireless Power Transmission (WPT) and an insight into the working principle of solar power generation was presented. It was observed that despite the various prospects that were identified by the various researchers less attention was paid to the means of enhancing the range of transmission of solar power satellite

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”.

Capacity Structure

The paper dwells upon the problem of multi-criteria choice of ways to develop generating capacities to supply power to remote consumers. We herein propose a two-step multi-criteria analysis method: choosing promising power-generation technology first, and then specifying the generating-capacity structure. The paper describes the structure of the proposed multi-criteria methods: the interval TOPSIS method for Step 1; for Step 2, an upgraded analytic hierarchy process based on identifying the structure of the decision maker’s preferences. We demonstrate the use of this method with evidence from the Penzhinsky District, Kamchatka Krai. Thermal power plants, hydroelectric power plants, diesel power plants, as well as solar and wind power are analyzed as power sources. Step 1 includes: analyzing the potential power-supply loads in a specific area; formulating alternative power-generation technology; formulating goals and criteria; criterion-based evaluation of alternative options using objective and subjective models; multi-criteria evaluation of alternatives; analyzing the sensitivity of results and the selection of promising technology. Step 2 includes: formulating goals and criteria on the basis of the selected power-generation technologies; formulating the available alternatives; criterion-based evaluation of alternatives; multi-criteria evaluation and final decision-making.

Thermoelectric technology offers the opportunity of direct conversion between heat and electricity, and new and exciting materials that can enable this technology to deliver higher efficiencies have been developed in recent years. This mini-review covers the most promising advances in thermoelectric materials as they pertain to their potential in being implemented in devices and modules with an emphasis on thermoelectric power generation. Classified into three groups in terms of their operating temperature, the thermoelectric materials that are most likely to be used in future devices are briefly discussed. We summarize the state-of-the-art thermoelectric modules/devices, among which nanostructured PbTe modules are particularly highlighted. At the end, key issues and the possible strategies that can help thermoelectric power generation technology move forward are considered. This article is part of a discussion meeting issue ‘Energy materials for a low carbon future’.
