In this study, the thermal characteristics of 3 mangrove biomass (leaf, stem, and roots) of natural and replanted gray mangrove (species: <em>Avicenna marina)</em> reserves have been investigated in an inert medium and compared to assess their fuel production potential. The chemical composition, physiochemical properties, and thermal behavior by proximate and ultimate analyses and thermogravimetric analysis (TGA) were investigated for this. Transplanted stem biomass showed the least ash content, with higher volatile contents when compared to other biomass samples. The higher heating value (HHV) in natural mangrove stems was 16.29 MJ/kg, with a calorific value (CV) of 16.58 MJ/kg, whereas the HHV in replanted mangrove stems was higher at 17.50 MJ/kg, with a CV of 22.41 MJ/kg. The apparent kinetic parameters, including activation energy and frequency factor, were estimated by fitting the experimental data to the n^th-order rate model. The apparent activation energies ranged from 73.2 to 78.5 kJ/mol for leaves, 96.0 to 97.3 kJ/mol for the stem, and 71.5 to 94.5 kJ/mol for roots, which are less than other mangrove species, indicating gray mangrove biomass was more reactive. Statistical analysis (e.g., Pearson correlation, <em>t</em>-test) indicated strong similarities and negligible differences between the experimental and simulation results. Several environmental factors (e.g., pH and salinity of soil) at study locations were investigated, suggesting higher HHV and carbon content of replanted mangrove stem biomass was noticeable due to higher salinity.

Biomass gasification could open the path toward renewable fuel production, waste valorization, and carbon capture, but a fraction of the initial feedstock is burnt for process heat. Hence, allothermal solar heating is an attractive option for a clean and efficient production of syngas, enabling solar energy storage under a chemical form. Solar gasification potentially converts the whole feedstock mass while the produced syngas is not contaminated by combustion by-products and the high temperatures help to ensure high syngas yields with minimized char and tars production. Such results were however obtained under favorable solar power input conditions. In practice, the solar power fluctuations and intermittency must be managed carefully, with a control of the reactor inputs round the clock for stable syngas production. This review aims to provide a state-of-the-art on the variety of scientific topics involved in developing a stable and controllable solar gasification process, and it further addresses the challenges of hybridized solar-autothermal processes. Conventional gasification is first tackled, unraveling the historical background and current applications of the process. Associated chemical mechanisms are described, with some modeling considerations. Concentrated solar power technologies are then described, with a focus on thermochemical applications and existing solar gasification technologies. Finally, the methods to smoothen the effects of fluctuating solar power availability on solar syngas production are assessed, including thermal heat storage and solar-autothermal hybridization for continuous day-night operation. The implementation of dynamic control methods is addressed, to assess the practical application of control strategies, paving the way toward continuous solar fuels production.</div></div>","PeriodicalId":100957,"journal":{"name":"Next Energy","volume":"8 ","pages":"Article 100277"},"PeriodicalIF":0.0,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143800659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hydrogen production mainly relies on fossil fuels (natural gas and coal). Hydrogen production from fossil fuels can result in the significant emissions of carbon dioxide, aggravating the global greenhouse effect. At the same time, fossil fuels are non-renewable, and the use of fossil fuels to produce hydrogen further exacerbates the crisis of fossil fuel shortages. Fortunately, water, as a carbon-free and hydrogen-rich renewable resource, offers one of the best solutions to replace hydrogen production from fossil fuels through its decomposition. Furthermore, hydrogen production by decomposition of water is vital for the realization of the sustainable development. In this paper, we review the current mainstream technologies (electrolysis, pyrolysis and photolysis) for hydrogen production by decomposing water. The principles, processes, advantages and disadvantages and the latest progresses of these technologies are also discussed. At last, this paper provides a summary and outlook on water decomposition for hydrogen production, and thinks that the yield, energy efficiency and cost of hydrogen production from water decomposition are largely dependent on the development of new materials and the improvement of existing materials.

However, utilizing microgrids in a more collaborative manner might greatly enhance the integration of renewable energy sources into the electricity network. The primary objective of this research is to improve the quality of information communicated from MGs to the utility grid to achieve production levelling. Multiple simulation scenarios have been developed to analyse the performance of a grid-connected MG when the grid order update rules are altered. The findings indicate that the suggested scenarios for collaborative MGs, especially the scenario that relies on forecasted demand for precontracted order updates (COU), are enhancing system performance by stabilizing order volatility to the grid (58% less unplanned volatility of orders in the collaborative MG), thereby reducing the carbon footprint of the MG by 67% and increasing storage utilization by 74%. The only limitation was the volume of exported electricity; however, the implementation of long- term storage capacity (seasonal storage) has effectively reduced the exported power to 0. A distinct trade-off exists between enhanced storage capacity at a higher cost and a significant volume of exported power. The optimal resolution for this trade-off is greatly affected by the initial investment in storage technology and the feed-in tariff rate for exported power.

It was also found that the energy storage performance can be improved by using fine mesh electrodes, which increases the effective contact area for energy storage. On the other hand, durability becomes an issue if the mesh opening is too small because smaller mesh opening leads to thinner mesh wires.
