“…We also hypothesized that the decrease in the flow rate of CO 2 would increase the residence time of the etching reaction resulting in the increased probability of CO 2 diffusion onto the reaction sites and thus enhancing the overlapping of electrostatic potentials across the ultramicropore walls. On the contrary, an increase in activation time results in the attack of pore walls, thus yielding more mesoporous carbons. − …”

In the face of urgent global challenges such as climate change, escalating energy demands, and security concerns, the shift toward sustainable and low-carbon energy is imperative. Hydrogen (H 2 ), recognized as a versatile and clean energy carrier, holds significant promise as a key facilitator in achieving these objectives. However, H 2 encounters challenges in becoming a reliable energy carrier due to issues related to energy density, ease of storage, and compatibility with existing infrastructure. This paper presents a comprehensive investigation of microstructure engineering in high surface area carbon aerogels to enhance H 2 uptake, addressing a pivotal aspect of H 2 storage applications. We report engineering microstructure of ultramicroporous carbon aerogels via sol−gel and CO 2 supercritical drying methods, as potential H 2 sorbent carriers. Microstructural analysis via N 2 , Ar, and CO 2 physisorption measurements revealed that the alteration of microstructure in carbon aerogels through controlled pyrolysis, activation, and pore-forming techniques facilitated the formation of ultramicropores with favorable confinement effects which enhanced intermolecular interactions across the pore walls toward efficient H 2 adsorption. The carbon aerogels, regardless of activation methods, exhibited elevated surface areas between 2970 and 3200 m 2 /g and pore volumes in the range of 0.7−1.39 cm 3 /g, with a microporous surface area ranging from 950 to 2610 m 2 /g. Notably, the double-activated carbon aerogel (CA T20-F25-KOH ) demonstrated the highest H 2 storage capacity of 2.1 wt % and 6.8 g/L under 298 K and 100 bar pressure. At cryogenic temperature (77 K) and 100 bar pressure, CA T20-F25-KOH achieved a H 2 storage capacities of 6.8 wt % and 28 g/L. These findings underscore the pivotal role of porosity and surface chemistry in carbon sorbents for H 2 storage.

“…Of course, for such a multidisciplinary study, agricultural products must be usable material forms for energy storage cells. For example, products such as coconut, walnuts, and hazelnuts can be carbonized and used as electrodes in powder form (Javed et al,2021;Kucuk et al, 2021;Wang et al, 2021). The other products are similarly carbonized and have the potential to be used in energy storage systems in powder form.…”

Nowadays, the energy and agriculture sectors are united for financial efficiency, and it brought the question to minds “can be stored the electrical energy that used in agriculture with an agricultural product?”. In this study, lavender essential oil, it obtained from Lavandula angustifolia, was used as a part of energy storage system. The essential oil was produced by distillation method. To energy storage performance analysis, the simple electrochemical capacitor was formed with platin foils and lavender essential oil. The capacitor application performances showed that the lavender essential oil can energy storage up to 4 Voltages (V). A capacity of 92 milli-Farad per cm2 (mF/cm2) was obtained with Lavender essential oil in the range of 0-4 V, and this value showed that lavender essential oil can be used in capacitors, as an electrolyte material. The results when evaluated in terms of agricultural economics, 1 million capacitors with a size of 1 cm2 can be produced with 1 ton lavender crops production per decare. Moreover, with lavender capacitors, the amount of energy required for a farm of 1000 hectares can be stored with 1000 capacitors of 10 cm2. Also, the stored energy is more than the farm's annual energy consumption, saving the farm ~534 USD annually on energy costs. In the case that all farm energy is produced with renewable energy sources, the annual profit is calculated as ~23697 USD. Also, the exploring of electrochemical capacitor electrolyte property of lavender essential oil could create an alternative sales pitch for agricultural producers.
