“…In fact, the scarcity of electricity storage may be the “ball-and-chain” that prevents intermittent renewables from breaking free and reaching the implementation levels predicted by mid-century. 27 Indeed, according to Bloomberg Technology News, Germany had to throw away 4% of its wind energy in 2015, China had to discard 17% of its renewable energy, and California had to discard 300,000 MWh of renewable energy in the first half of 2017, all caused by a lack of adequate electricity storage ability. 28, 29 Rapid expansion of renewable energy production might potentially be an unreasonable financial burden without enough electricity storage capacity.…”

Energy systems are progressive and revolutionary for their alternative resources, technical developments, demands, effectiveness and environmental effects. The recently published research's goal is to assess and evaluate the systems that are already in operation and those that will be in the future. Energy can be stored as electrical energy such as supercapacitors (SCs) and superconducting magnetic energy storage (SMES) etc., mechanical energy such as pumped hydro energy storage (PHES), compressed air energy storage (CAES) and flywheel energy storage (FES) etc., chemical energy, electrochemical energy such as batteries and fuel cells etc., and thermal energy. Performance of these energy storage systems (ESSs) have been evaluated in terms of energy density, power density, power ratings, capacitance, discharge-time, energy-efficiency, life-time and cycling-times, and costs. Supercapacitors provide highest power density (>10,0000 W/l), while hydrogen fuel cells provide highest energy density (500-3000Wh/l) among other EESs. Batteries also provide high energy density(200-500Wh/l). The energy efficiency is found highest in SMES system (95-98%), and lowest in TES system (30-50%). Moreover, batteries and supercapacitors have the cycle efficiency above 90%. PHES and CAES seem to be the most cost-effective energy storage systems reviewed in this analysis in terms of $/kWh. In addition, power-based capital cost of supercapacitors is lower (100-300$/kW) compared to energy-based capital cost of supercapacitors (300-2000$/kWh). In comparison with power-based capital costs, the energy-based capital cost of batteries is lower, which is 150-400$/kWh for Lead-acid battery, and <300$/kWh for Li-ion battery. This essay may help researchers in choosing the advanced energy storage technologies for relevant purposes.

“…As higher efficiencies reduce CO 2 emissions, the technology is of interest considering that coal is poised to remain one of the world's main energy sources, at least over the next few decades [2,3]. The exhaust stream from an optimised CFC is expected to have high concentrations of CO 2 and can be easily sequestered and captured compared with a diluted CO 2 stream from traditional coal-fired power plants [4,5]. Despite the technical advantages of CFCs, several technical challenges remain to be addressed, including fuel delivery to the active sites at the fuel electrode/electrolyte interface and continuous supply of solid carbon to the anode chamber.…”

A carbon fuel cell (CFC) is an emerging technology for conversion of solid carbonaceous material into electricity at high theoretical efficiencies (100 %). As carbonaceous material like coal will remain an important energy source for the next few decades, the development of technology that can use it more efficiently is critical to reduce emissions. For practical operation of a CFC, a continual supply or consecutive refuelling of solid carbon fuel is required. Here, we investigated the electrochemical performance and durability of a CFC using a scandia-zirconia tubular electrolyte with Ce 0.9 Gd 0.1 O 2 -Ag electrodes with activated charcoal fuel. We demonstrated that CFCs can be operated in a batch-type process with refuelling and utilisation of fuel. Peak power densities up to 280 mW cm −2 were obtained without major materials degradation. We expect that advances to engineering of fuel delivery will improve the long-term stability and performance of the cells.

“…In this regard, laborious endeavors have been dedicated to inaugurate glucose sensors with excellent selectivity, notable receptivity, good reliability, inexpensive, and fast response due to its growing demands for pharmaceutical analysis, advanced blood sugar detection, for food and ecological monitoring and control of bioprocess. [1][2][3][4][5] Similarly, the non-enzymatic glucose sensors have preference over enzymatic sensors owing to their defects such as difficult enzyme immobilization, operating condition such as critical temperature, pH, high cost, humidity and chemical instability. [6][7][8] To diminish the aforementioned issues, the innovation of enzyme free sensors has been proposed and demonstrated as a promising perspective era.…”

One of the important factors to recover the quality of lifespan of diabetic patients is continuous intensive care of glucose to deliver information for more precise diagnosis and treatment. Up-to-date an incessant glucose sensor uses enzymes with a one-to-twoweek lifespan, which forces episodic replacement. In this context, metal oxide sensor is considered as a substitute to enzymatic sensors owing to the longer lifetime. The present research demonstrate a simplistic conglomeration of nickel hydroxide (Ni(OH) 2 ) and nickel oxide (NiO) nano-particles via a microwave radiation method followed by deposition on a highly porous 3D nickel foam substrate dissipating nickel nitrate Ni(NO 3 ) 2 as the nickel source with sodium hydroxide (NaOH) as the starting material. The resultant polycrystalline NiO films were annealed and characterized by various techniques. Electrochemical studies reveal that the NiO manifested magnificent stability and outstanding catalytic activity for electrocatalytic oxidation of glucose in the aqueous solution of sodium sulfate (Na 2 SO 4 ), enabling an enzyme-free amperometric sensors for glucose designation. The nanorod arrays on distinctive 3D substrate are anticipating to accelerate the sensitivity and efficiency of NiO based electrochemical sensors and heterogeneous catalysts. The NiO based glucose biosensor offered improved properties having extensive linear reciprocation window for glucose concentrations, concise retaliation time, lower recognition level, prominent sensitivity as well as good stability and recyclability.
