Stationary Fuel Cell System
Fuel cell technologies have several applications in stationary power production, such as units for primary power generation, grid stabilization, systems adopted to generate backup power, and combined-heat-and-power configurations (CHP). The main sectors where stationary fuel cells have been employed are (a) micro-CHP, (b) large stationary applications, (c) UPS, and IPS. The fuel cell size for stationary applications is strongly related to the power needed from the load. Since this sector ranges from simple backup systems to large facilities, the stationary fuel cell market includes few kWs and less (micro-generation) to larger sizes of MWs. The design parameters for the stationary fuel cell system differ for fuel cell technology (PEM, AFC, PAFC, MCFC, and SOFC), as well as the fuel type and supply.

Artificial Intelligence in the Effective Battery Life Cycle
The rapid growth of battery production and usage will cause waste and disposal-related issues as these batteries reach end-of-life. Moreover, it also causes the depletion of natural mineral resources. Thus, effective battery reuse and recycling procedures are highly important because they contain metals of critical importance. The recycling of batteries causes the return of valuable materials, including lead, lithium, nickel, cadmium, and copper, back to the value chain, partially easing the need to extract new resources. Moreover, recovering metals from batteries reduces the burden on landfills, the burden on the environment, and the negative impact on human health. The critical material’s recirculation also leads to a reduction of the ecological CO2 footprint, which is connected with battery cell production and may provide CO2-neutral battery cell production. Improper battery waste disposal causes harmful effects on human and animal health, as well as the environment, as they contain a huge number of heavy metals. These waste compounds contaminate water, soil, and vegetation.

Biomass Feedstock
The importance of energy demands that have increased exponentially over the past century has led to the sourcing of other ideal power solutions as the potential replacement alternative to the conventional fossil fuel. However, the utilisation of fossil fuel has created severe environmental issues. The identification of other renewable sources is beneficial to replace the energy utilisation globally. Biomass is a highly favourable sustainable alternative to renewable resources that can produce cleaner, cheaper, and readily available energy sources in the future. The palm oil industry is essentially ideal for the availability of abundant biomass resources, where the multifaceted residues are vital for energy production through the conversion of biomass waste into value-added products simultaneously. This article discusses the utilisation of palm oil and its residues in the energy and transportation sector. Assessment and evaluation on the feasibility of palm oil and its residues were made on the current valorisation methods such as thermochemical and biochemical techniques. Their potential as transportation fuels were concurrently reviewed. This is followed by a discussion on future challenges of palm oil industries that will take place globally, including the prospects from government and non-government organisations for the development of palm oil as a sustainable alternative replacement to fossil fuel. Hence, this review aims to provide further insight into the possibilities of palm oil and its residues towards sustainable development with reduced environmental-related issues.

Evaluating Geothermal Systems through Life Cycle Assessment
In these days of heightened environmental consciousness, many countries are shifting their focus towards renewable energy sources for both large-scale uses (such as power plants that generate electricity) and smaller-scale applications (e.g., building heating and cooling). Taking into account a holistic method, LCA on the one hand allows to display the whole life cycle of a system from the extraction of raw materials, its creation to the production phase and finally to its disposal. On the other hand, it reveals through multiple environmental impact categories, the hot spots that account for the different stages of the cycle defining the environmental identity of the system and consequently driving policy makers on taking final decisions. Geothermal energy is an extremely viable alternative that, combined with other renewable energy systems, may mitigate the negative effects of the existing energy mix worldwide.

Nanocatalysts Used in AOPs for Wastewater Treatment
The increase in population demands for industrialization and urbanization which led to the introduction of novel hazardous chemicals in our environment. The most significant parts of these harmful substances found in water bodies remain in the background, causing a health risk to humans and animals. It is critical to remove these toxic chemicals from the wastewater to keep a cleaner and greener environment. Hence, wastewater treatment is a challenging area these days to manage liquid wastes effectively. Therefore, scientists are in search of novel technologies to treat and recycle wastewater, and nanotechnology is one of them, thanks to the potential of nanoparticles to effectively clean wastewater while also being ecologically benign. Advanced oxidation processes (AOPs) have been extensively studied. Advanced oxidation processes can be defined as the processes and technologies which involve the generation of active species such as hydroxyl radicals (•OH) which act as efficient oxidants to decompose pollutants in wastewater treatment.

EU Road Transport Carbon Emissions
To accomplish the 1.5 °C and 2 °C climate change targets, the European Union (EU) has set up several policy initiatives. Within the EU, the carbon emissions of the road transport sector from the consumption of diesel and gasoline are constantly rising. (1) Background: due to road transport policies, diesel and gasoline use within the EU is increasing the amount of carbon in the atmosphere and adding to climate risks. (2) Methods: sustainability analysis used was based on the method recommended by the Intergovernmental Panel on Climate Change. (3) Results: to meet its road transport requirements, the EU produces an estimated 0.237–0.245 billion tonnes of carbon per year from its total consumption of diesel and gasoline. (4) Conclusion: if there is no significant reduction in diesel and gasoline carbon emissions, there is a real risk that the EU’s carbon budget commitment could lapse and that climate change targets will not be met. Sustainability analysis of energy consumption in road transport sector shows the optimum solution is the direct electrification of road transport.
