“…The German "Energiewende" poses demanding challenges with regard to the development, operation and maintenance of flexible, regenerative energy converters and storage systems (e.g. pumped thermal electricity storage [1,2], concentrating solar power [3,4], biomass firing, power-to-X technologies [5], etc...) and conventional back-up power plants. At present, development is focused on process related issues, with development of new materials, suitable to meet future requirements, not playing a major role.…”

Future, flexible thermal energy conversion systems require new, demand-optimized highperformance materials. The High performance Ferritic (HiperFer) stainless steels, under development at the Institute of Microstructure and Properties of Materials (IEK-2) at Forschungszentrum Jülich GmbH in Germany, provide a balanced combination of fatigue, creep and corrosion resistance at reasonable price. This paper outlines the scientific background of alloy performance development, which resulted in an age-hardening ferritic, stainless steel grade. Furthermore, technological properties are addressed and the potential concerning application is estimated by benchmarking versus conventional state of the art materials.

“…Fresnel lenses replace the curved surfaces of conventional lenses with a series of concentric grooves, printed on a thin and light plastic sheet. Slots act as individual refracting surfaces, like small prisms when viewed in a cross-section, bending parallel rays in estimates that are very close to the typical focal length [20][21][22].…”

Energy-saving technologies and equipment 31 in Indonesia comes from fossil energy sources. Until 2019, power plants in the country are still dominant from conventional energy sources, including coal (50 %), followed by natural gas (29 %), fuel (7 %). While the use of renewable energy is only about 14 %, and for solar energy, utilization is less than 1 % [1]. Currently, the largest energy user in Indonesia is the industrial sector by 36 %, the transportation sector by 40 %, the household sector by 16 %, and the commercial sector by 6 %. 1. Introduction Solar thermal energy is one of the potential energy to be managed and developed further as a source of energy reserves, especially for countries located on the equator, including Indonesia, where the sun shines throughout the year. The potential of solar power in this region can reach 5.1 kWh/m 2 /day (Eastern Indonesia) and 4.5 kWh/m 2 /day (Western Indonesia). However, the majority of energy use

“…For CSP plants with central receiver system, heliostat field is the optimum option as this configuration provides higher temperatures for the central receiver as compared to line focus systems. 54 The central receiver collects radiations and converts them to thermal energy depending upon the receiver design and heat transfer mediating fluid. The thermal energy by the central receiver is absorbed by the heat transfer fluid by convection and the mediating fluid circulates in solar thermal loop and exchanges heat by the working fluid present in power loop.…”

To meet heating demand without global warming is a huge target for the energy community these days. To attain this challenge, solar energy harvesting to meet domestic hot water demand is a promising solution. Carbon dioxide (CO 2) is becoming ever more significant as heat transporting fluid. Simulationbased efficiency assessment models are requisite for analogous advances. This research presents a dynamic simulation model of high temperature concentrated solar plant using directly heated molten salt to indirectly power a supercritical CO 2 Brayton cycle. Target of the study is to achieve 1 MW generation and simulation work is performed in TRNSYS computer software. The operating conditions for the plant cycle and efficiency for indirectly heated CO 2 recompression Brayton cycle are also calculated with the help of engineering equation solver. The system is divided into three major loops: solar thermal heat collection, power generation, and heat recovery. Results have shown overall cycle efficiency up to 40%. During the day hours from 4688 to 4697, receiver provides a constant outlet temperature of 700 C with a fluid inlet flow rate of 15 kg/s and mediating fluid after exchanging heat enters the receiver's end at 524 C. An optimized value of 2.9 is selected as pressure ratio to meet supercritical conditions at the compressor inlet. Output power generated is 3.035 MW with turbine efficiency is 92%. The power calculated for main compressor and recompressor are 0.68 and 0.228 MW, respectively.
