“…Renewable energy is a good initiative but it seems hard to harvest so much energy to replace fossil fuels. However, nuclear fusion and artificial synthesis are Lexus Nexus to rescue global energy systems 12 . Conventional fossil fuels, biomasses, nuclear and biochemical technologies are piling up air pollution, plastics, nuclear and biochemical wastes worldwide.…”

“…Humankind needs fresh air, clean water, and nutrient food to survive. Air pollution issue has arisen from the long hauled combustion of fossil fuels, but food and water have remained the central raison d'être behind most ancient wars 11‐14 . As food and water are necessary for continuity of life, clean air is also basic need of humans to survive on planet.…”

We present the role of heat and electricity storage systems on the rapid rise of renewable energy resources and the steady fall of fossil fuels. The upsurge in renewable resources and slump in fossil fuel consumptions is attributed to sustainable energy systems, energy transition, climate change, and clean energy initiatives. The fast growth of renewables brings new design and operational challenges to transition towards 100% renewable energy goal. Energy storage systems can help ride‐through energy transition from hydrocarbon fuels to renewable sources. Nuclear fusion and artificial photosynthesis are the ultimate Holy Grails for permanent clean energy solutions. Plants harvest light and store it in chemical energy to regulate the food supply chain that may be a guideline for an energy transition from fossil fuels to renewables. Heat and electricity storage devices can account for the periodic nature of solar and wind energy sources. Solar thermal systems for water and space heating are also a viable solution for subzero temperature areas. This study presents the transition of world's energy prospect from fossil fuels to renewables and new advances in energy storage systems.

“…A risk of 0.15 million additional causalities is expected due to severe environmental conditions, water shortages, hunger, flooding, and desertification. [1][2][3][4][5] Fossil fuels are limited in quantity and are being depleted at a rate higher than discovery which not only projecting fuels prices but will also engender a plummet in lifestyle by their increased demand over more than 50% till 2035. 6 Moreover, burning of these fossils in power and automotive industry contributes at least 90% of total carbon dioxide (CO 2 ) emissions in earth's atmosphere.…”

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.

In the quest of renewable energy technologies, solar photoreforming emerges as one of the affordable yet challenging process for converting biomass into hydrogen, hydrocarbon fuels, and chemicals. This review highlights the state‐of‐the‐art photoreforming, elucidating its underlying mechanisms for the conversion of dissipated polymers into H2 and valuable chemicals. Biomass feedstocks such as carbohydrates, agricultural residues, glycopolymers, food wastes, and waste plastics are evaluated based on their chemical composition, energy content, and sustainability aspects, exploring the selection of appropriate bio‐renewable resources, considering their abundance, availability, and potential for hydrogen production. The impact of diverse process parameters on photoreforming efficiency is explored, encompassing factors like reaction temperature, pH, catalyst loading, reactor design, solvent effect, and light intensity across various sacrificial substrates. The discussion also considers their correlation with hydrogen production rate, selectivity, and energy efficiency. This review buckles on the design and synthesis of functional photocatalysts for biomass‐derived feedstock, highlighting their photocatalytic (PC) properties in biomass reforming processes and related feedstock into valuable chemicals and biofuel. The review also delves into potential pathways for future advancements including artificial intelligence (AI) and machine learning (ML), alongside addressing the challenges and insightful perspectives within this evolving field of future green energy.
