Artificial Intelligence Applied to Variable Renewable Energy Systems
The development directions of artificial intelligence (AI) for variable renewable energy (VRE) are of paramount importance in navigating the challenges and optimizing the utilization of renewable energy sources. As the global energy landscape undergoes a transformative shift towards increased reliance on VRE, AI offers strategic avenues to enhance the efficiency, dependability, and eco-sustainability of these systems. The integration of AI methodologies in VRE management addresses complexities related to data quality, model transparency, and system optimization. The burgeoning digitalization of energy supplies, coupled with the dynamic nature of VRE, necessitates innovative solutions to harness the full potential of renewable sources. AI has the potential to contribute significantly to overcoming inherent challenges, not only paving the way for improved energy forecasting, distribution, and system control but also through fostering a more sustainable and resilient energy paradigm in line with the demands of a rapidly evolving global climate and energy landscape.

Renewable Energy and Decarbonization in Canadian Mining Industry
Mining in Canada stands as one of the most energy-intensive sectors, playing a pivotal role as a significant provider of copper, nickel, and cobalt to the international market. Anticipated growth in the global population, coupled with the transition of several low-income economies to middle-income status, is poised to escalate the demand for essential raw materials. This surge in demand is expected to drive an increase in energy consumption across various stages of the Canadian mining industry, encompassing exploration, extraction, processing, and refining. Due to their geographical constraints, most Canadian mining operations rely heavily on fossil fuels such as diesel and heavy fuel. Considering the global shift towards decarbonization and the pursuit of net-zero emission targets, exploring avenues for adopting electrification solutions and integrating renewable energy technologies, particularly in sizable surface mines, is imperative.

Electrochemical Energy and Carbon Cycle
Green hydrogen, green ammonia, and green methanol are being widely discussed for shipping. Because green methanol and ammonia have higher energy densities and are relatively easier to transport and store on ships, they have become the most promising near-zero-emission marine fuel. In addition, since most of the production pathways for green fuel require green power, the production methods for green power are analyzed in detail.

Energy Storage Systems in Microgrids
Energy storage systems (ESSs) are commonly used to shift the electric energy time and reduce operation costs by storing electrical energy during low-cost and excess power periods and injecting power during peak hours. Energy storage technologies have a wide range of applications in microgrids, including providing backup power and balancing the supply and demand of energy.

Low-Emission Waste-to-Energy Method of Liquid Fuel Combustion
Waste-to-energy approaches, aimed at using cheap energy carriers (oil production and refining waste, etc.), require the creation of new technologies with high energy efficiency and low emissions. One of the environmentally friendly methods is a superheated steam injection (SIM) into the combustion zone. At the same time, trends in CO2 reduction and recycling make carbon dioxide more attractive to use together with, or instead of, steam.

Two-Sided Matching in Coal Mining and Power Generation
Under the current marketized coal and planned electricity price systems, barriers to price shifting between coal and electricity are created and conflicts between the two sectors are aggravated. The stable trading matching between coal mining and power generation companies is not only an effective means to resolve the conflict in the coal trading market, but also a ballast stone for price stabilization and supply guarantees in coal trading.

Reuse of Wind Turbine Blades
The sustainability of wind power has been called into question because there are currently no truly sustainable solutions to the problem of how to deal with the non-biodegradable fibre-reinforced polymer (FRP) composite wind blades (sometimes referred to as “wings”) that capture the wind energy. The vast majority of wind blades that have reached their end-of-life (EOL) currently end up in landfills (either in full-sized pieces or pulverized into smaller pieces) or are incinerated. The problem has come to a head since many countries (especially in the EU) have outlawed, or expect to outlaw in the near future, one or both of these unsustainable and polluting disposal methods. An increasing number of studies have addressed the issue of EOL blade “waste”; however, these studies are generally of little use since they make predictions that do not account for the manner in which wind blades are decommissioned (from the time the decision is made to retire a turbine (or a wind farm) to the eventual disposal or recycling of all of its components).

Pyrolysis Technologies
Biomass-based solutions have been discussed as having the potential to replace fossil-based solutions in the iron and steel industry. To produce the biocarbon required in these processes, thermochemical treatment, pyrolysis, typically takes place. There are various ways to produce biocarbon, alongside other products, which are called pyrolysis oil and pyrolysis gas. These conversion methods can be divided into conventional and non-conventional methods.

Hydrogen Energy Systems and Renewable Energy Sources
The global energy production is currently characterized by an unprecedented shift to renewable energy sources (RES) and their technologies. However, the local and the environmental benefits of such RES-based technologies show a wide variety of technological maturity, with a common mismatch to local RES stocks and actual utilization levels of RES exploitation. Among contemporary sources of energy production, hydrogen can be characterized as an efficient and clean fuel. The role of hydrogen as a clean energy source is a promising but also a contentious issue. This multifaceted role of hydrogen utilization for clean energy production is literature-reviewed and technology-conveyed.

Electric and Hydrogen Automobile
The negative consequences of toxic emissions from internal combustion engines, energy security, climate change, and energy costs have led to a growing demand for clean power sources in the automotive industry. Developing eco-friendly vehicle technologies, such as electric and hydrogen vehicles, has increased. The researchers investigate whether hydrogen vehicles will replace electric vehicles in the future. The results showed that fuel-cell cars are unlikely to compete with electric cars. This is due to the advancements in electric vehicles and charging infrastructure, which are becoming more cost-effective and efficient. Additionally, the technical progress in Battery Electric Vehicles (BEVs) is expected to reduce the market share of Fuel-Cell Electric Vehicles (FCEVs) in passenger vehicles. However, there are significant investments in hydrogen cars. Many ongoing investments seem to follow the sunk cost fallacy, where decision-makers continue to invest in an unprofitable project due to the already invested resources. Furthermore, even with megawatt charging, fuel-cell trucks cost more than battery-powered electric trucks. The use cases for fuel-cell electric trucks are also much more limited, as their running expenses are higher compared to electric cars. Hydrogen vehicles may be beneficial for heavy transport in remote areas. However, it remains to be seen if niche markets are large enough to support fuel-cell electric truck commercialization and economies of scale. In summary, researchers believe hydrogen vehicles will not replace electric cars and trucks, at least before 2050.
