New analysis is presented identifying strong potential for Concentrating Solar Thermal technology (CST) to be a cost-effective contributor to future sources of net zero-emissions, high temperature industrial process heat relative to other emerging options. Nevertheless, significant further development of the technology is needed to realise this potential because the majority of previous investment in CST has targeted lower temperature applications in power generation, which employs different working fluids and typically operates at different scales. A comparison with the flame temperatures typically employed in current industrial processes, together with an allowance for thermal storage, suggests that receiver temperatures in the range of 1100 − 1500 °C will be needed to drive many current high-temperature industrial processes, which is far above the range of temperatures employed commercially and also above the range at which most pilot-scale work for CST has been undertaken to date. Technology development will therefore be needed to realise this potential, both for the solar thermal plant and for the industrial processing plant, since current reactors have been developed to utilise fossil fuels. More work is also needed to advance understanding of the best options with which to hybridise CST with another back-up energy source, such as hydrogen, since it is uneconomical to seek to manage seasonal variability with thermal storage alone.
A case study is then presented of the techno-economic performance of a system based on the solar expanding-vortex receiver, which has proven potential to operate at the required temperature range and also employs air as the Heat Transfer Media (HTM) to facilitate integration into existing industrial processes. This analysis summarises the first major assessment of a fully integrated system that considers the full path from the solar plant to the industrial processes with thermal storage and combustion back-up, using a transient model that accounts for one year of resource variability in 15 min time intervals. The complexity of the system is compounded by the interdependence of the performance of each component, whichmakes it challenging to optimise. For example, the costs of integrating the solar thermal output to the industrial plant can be comparable with that of the heliostat field for a single tower at scales of 50MWth. However, the relative cost of integration decreases with an increase in thermal scale. Importantly, the best of these systems is found to have good potential to provide cost-competitive Levelised Cost of Heat (LCOH) compared with projected costs for other options for net-zero heat, notably green electrical power and hydrogen with storage, provided that the solar resource is good. Furthermore, it is anticipated that further reductions in LCOH will be possible, both with further system optimisation and with future technology development, such as that employing alternative HTM includ

This article is a brief review of inventions, innovations, and commercialization aspects of solar desalination technology for clean water supply. It is estimated that by the year 2025, nearly two-thirds of the global population will be affected by clean water scarcity. Solar desalination is one of the most sustainable ways of facing this global challenge with emerging technological advancements. Highly efficient interfacial solar evaporation that localizes the heat on the evaporating surface has attracted tremendous research interest within the last few years. In addition, notable innovations can be found in adsorption desalination and energy-efficient freeze desalination. The mini review is followed by a list of notable recent patents and articles. However, the list is by no means exhaustive or complete, and quite possibly some important patents and articles are not cited. The mini review and the lists support the objective of this section: to draw attention to the topic of inventions, innovations and new technologies, which can be a major contributor to the global goal of net zero carbon emissions.

Residential and commercial facility users are looking for ways to reduce their energy bills; this has resulted in nano and micro solar energy production in the form of electricity prosumption in contemporary times. Several technical factors characterise rooftop solar projects informing the decision to go solar. Amongst these factors are the solar energy available from the PV system, self-consumption ratio and overall system efficiency. However, from the investor's viewpoint, the most critical factor is the economic viability of the proposed project. Since energy economics is vital to investors, the paper seeks to analyse the economics (financial feasibility and profitability) associated with different types of prosumers in Ghana's residential and commercial classes. The net present value, internal rate of return, profitability index, and discounted payback were the economic indicators used to appraise Ghana's financial feasibility and profitability of electricity prosumption. The study shows that electricity prosumption in Ghana is worth investing in. The best investment option in the residential and commercial classes is the prosumers with grid integration and without storage (type 2). In the residential tariff class, the best investment option is the prosumers, whose energy demands are between 301 kWh and 600 kWh.

The aim of the current study was to provide a review of recent developments in solar desalination from the viewpoint of environmental, regulatory, and economic aspects. The analysis attempted to give better insight into the larger question of why more solar desalination plants are not being established by reviewing different technologies, drivers, barriers, and markets. Critical barriers which were dependent on the level of regional development were found to be uncertainty of government subsidies and a lack of regulatory policies. A new tool called a Pareto frontier may be utilized to generate optimal points in complex scenarios with a high number of variables. This all-inclusive method should be employed in any major decision-making process. Furthermore, in exciting innovative research studies, a sustainable Janus wood evaporator was developed that overcame many of the current solar desalination problems. While subsidies were crucial in the growth of renewable energy programs, barriers in deployment of solar desalination systems still exist such as low electricity tariff structures and fragmented energy policies. The overall trend was towards integration of renewable energy with conventional sources and energy storage systems.

Off-grid power production utilizing renewable sources of power has become more significant and viable to meet the limited demands of remote locations. The primary goal of this study is to develop an economic and optimal hybrid PV/Biogas configuration for power production for rural common facilities including one Primary school, Junior school, and Panchayat Ghar buildings of Sarai Jairam village in Uttar Pradesh, India. Data on the electric load was gathered for two schools and Panchayat Ghar. The PV/biogas hybrid configuration was designed utilizing the Hybrid Optimization Model for Electric Renewable (HOMER) and techno-economic analysis is carried out to fulfill the load requirements. The available biomass potential and the data on solar irradiance of the study area were utilized in the HOMER software to carry out the analysis. The HOMER analysis produced a solution that included total net present cost (NPC) and cost of electricity (COE), and these results were then further improved using sensitivity analysis. The sensitivity analysis employed sensitivity parameters like biomass potential, biomass pricing, solar irradiance, and variation in loads. Based on the NPC and COE, this analysis evaluates the system performance and demonstrates that it is techno-economically feasible.

A technological revolution in both the cost and performance of solar photovoltaic (PV) technology has transformed the landscape of generating electricity directly from the sun in the last decade. Innovation combined with government incentives and policies led to massive investments which in turn fueled a virtuous cycle of declining PV costs with ever larger production volumes. The core electricity producing technology is scale neutral- a single solar module roughly the size of a typical door in a building, or a solar power plant with thousands of door-sized modules, all rely on the same solar cells.
They are all equally efficient at converting the sun's energy into electricity. This paper describes a case study of using the solar PV technology for small farmers in Senegal to reduce their costs, carbon foot print and collaborate with other farmers. The paper also gives recommendations for farmers in other developing countries based on the lessons learnt in this study. The lessons include benefit from bulk procurement, significantly lower per module cost of installation, logistics, transaction costs and interconnection to the grid.

This paper is based on a position paper of the German Industry Association Concentrated Solar Power e.V. to the German government and discusses options on how to decarbonize the heat demand of the domestic industry. Among other option, concentration solar collectors are a suitable option in Germany, which has not been expected by many experts. The paper derives requirements that are needed to ensure a quick and sustainable way to decarbonize industrial heat demand. They are considered to also be relevant for many other countries that follow the same ambition to become climate neutral in the next decades.
They major statements are:
• A mix of different renewable energy technologies in conjunction with efficiency measures is needed to ensure a secure, climate-friendly and cost-efficient heat supply for the industry
• The different technology options for the provision of heat from renewable sources, through electrification and through hydrogen can and must be combined and integrated with each other.
• In this context, concentrating solar thermal represents an important part of the hybrid supply portfolio of a decarbonized industry
This requires:
• The definition of an expansion target for process heat and the flanking measures
• Ensuring the equivalence of renewable heat, renewable electricity and green hydrogen - also as hybrid solutions
• The promotion of concentrating solar thermal reference projects as an impetus for market ramp-up in Germany
• The launch of an information campaign for heat consumers and the establishment of a pool of consultants.

In this article we have briefly reviewed inventions, innovations, and commercialization aspects of paints and coatings that can provide passive cooling without the use of mechanical refrigeration equipment. Solar reflective coatings have been available in the market for a long time and are in use for reflective roofs of commercial buildings. In this paper, we have reviewed recent developments of thin coatings that not only reflect solar radiation but also emit radiation in the atmospheric window, which further cools the surfaces. We reviewed the recent developments in coating fabrication that would lead to commercialization of these coatings. The review is followed by a list of notable recent patents and articles. However, the list is by no means exhaustive or complete, and quite possibly some important patents and articles might be missing. However, the review and the lists support the objective of this section to draw attention to the topic of inventions, innovations and new technologies, which can be a major contributor to the global goal of net zero carbon emissions in the world.
