This paper analyzes a novel, cost-effective planar waveguide solar concentrator design that is inspired by cellular hexagonal structures in nature with the benefits of facile installation and low operation and maintenance cost. A coupled thermal and optical analysis of solar irradiation through an ideal hexagonal waveguide concentrator integrated with a linear receiver is presented, along with a cost analysis methodology, to establish the upper limit of performance. The techno-economic model, coupled with numerical optimization, is used to determine designs that maximized power density and minimized the cost of heat in the temperature range of 100–250 °C, which constitutes more than half of the industrial process heat demand. Depending on the incident solar irradiation and the application temperature, the cost of heat for the optimal design configuration ranged between 0.1–0.27 $/W and 0.075–0.18 $/W for waveguide made of ZK7 glass and polycarbonate, respectively. A techno-economic analysis showed the potential of the technology to achieve cost as low as 80 $/m2 and 61 $/m2 for waveguide made of ZK7 glass and polycarbonate material, respectively, which is less than half the cost of state-of-the-art parabolic trough concentrators. Overall, the hexagonal waveguide solar concentrator technology shows immense potential for decarbonizing the industrial process heat and thermal desalination sectors.

It is already 10 years since the (European) High Temperature Reactor Technology Network (HTR-TN) launched a program for development of HTR technology, which expanded through three successive Euratom framework programs, with many projects in line with the network strategy. Widely relying in the beginning on the legacy of the former European HTR developments (DRAGON, AVR, THTR, etc.) that it contributed to safeguard, this program led to advances in HTR/VHTR technologies and produced significant results, which can contribute to the international cooperation through Euratom involvement in the Generation IV International Forum (GIF). the main achievements of the European program, performed in complement to efforts made in several European countries and other GIF partners, are presented: they concern the validation of computer codes (reactor physics, as well as system transient analysis from normal operation to air ingress accident and fuel performance in normal and accident conditions), materials (metallic materials for vessel, direct cycle turbines and intermediate heat exchanger, graphite, etc.), component development, fuel manufacturing and irradiation behavior, and specific HTR waste management (fuel and graphite). Key experiments have been performed or are still ongoing, like irradiation of graphite and of fuel material (PYCASSO experiment), high burn-up fuel PIE, safety test and isotopic analysis, IHX mock-up thermohydraulic test in helium atmosphere, air ingress experiment for a block type core, etc. Now HTR-TN partners consider that it is time for Europe to go a step forward toward industrial demonstration. In line with the orientations of the “Strategic Energy Technology Plan (SET-Plan)” recently issued by the European Commission that promotes a strategy for development of low-carbon energy technologies and mentions Generation IV nuclear systems as part of key technologies, HTR-TN proposes to launch a program for extending the contribution of nuclear energy to industrial process heat applications addressing (1) the development of a flexible HTR that can be coupled to many different process heat and cogeneration applications with very versatile requirements, (2) the development of coupling technologies for such coupling, (3) the possible adaptations of process heat applications required for nuclear coupling, and (4) the integration and optimization of the whole coupled system. As a preliminary step for this ambitious program, HTR-TN endeavors to create a strategic partnership between nuclear industry and R&D and process heat user industries.

This paper aims to analyze the planning method of low carbon technologies. It is a follow up to our previous analysis of sustainability assessment of low carbon strategies concerning economic, environmental and social terms. Construction sector in Chongming Island, Shanghai is analyzed as a case study. Eleven main building energy saving technologies are evaluated, and CO2 emission reduction amount and required building areas in 2030 in Chongming Island are set by using Decoupling Theory and Goal Programming method. The minimum emission reduction cost is found as 7.87×108 RMB under low carbon scenario and 9.52×108 RMB under ideal scenario. Planning analysis result also show that the low carbon scenario is possible to meet as the required building area is around 20% of the estimated building area in 2030. The ideal scenario will require more intensive energy saving technology application as the building area requirement is found around 40%.

This study examines the occurrences of thunderstorm and rainfall as indicator of climate change in Potiskum and its environs through exploring the decadal recorded data of rainfall and thunderstorm. The data obtained were used to analyze the changes and activities of thunderstorms with rainfall, and thunderstorms without rainfall for each month of the 30 years under study. A descriptive and Inferential statistics was employed to determine the frequency and trend of thunderstorm activities as well as the intensity of rainfall. The analysis indicated that there was decrease in thunderstorm occurrences from first decade (1987 - 1996), second (1997 - 2006) to third decade (2007 - 2016). The results also showed that there was an increase of rainfall intensity in the third decade and decrease in second decade. The results further indicated that there was a climatic change in thunderstorm and rainfall activities in Potiskum and its environs during the study period, and this serves as good indicator of climate change in the study area. Therefore, it is recommended that Nigeria should develop capacity for research and data collection, to monitor climate change impacts, formulate and implement policies to protect natural resources, including forests, and conserve energy based on clean and low carbon technologies.

To overcome the negative environemental impact of the actual power system, an optimal description of quasi-static electromagnetics relying on a reversible interpretation of the Faraday’s law is given. Due to the overabundance of carbon-free energy sources, this description makes it possible to consider an evolution towards an energy system favoring low-carbon technologies. The management for changing is then explored through a simplified linear-programming problem and an analogy with phase transitions in physics is drawn.
