Energy demand has grown rapidly with increase of global population. Surge in energy consumption is mainly driven by both economic and technological advancement. The conventional fossil fuels sources (coal, oil, and natural gas) and nuclear energy are depleting in nature known as non-renewables. Burning of fossil fuels contribute significant amount of greenhouse gases emissions, which negatively impact the global ecosystem. Access to energy is essential for modern civilization, yet we must seek alternative energy sources to protect our planet by controlling the emissions. Capturing harmful Green House Gases (GHG) with the help of advanced technologies helps reduce the risk to some extent. However, alternative energy sources must be renewable and sustainable. Renewable energy resources vary by geographical location and include solar, wind, hydro, and bioenergy, among others. The most appealing primary benefits of renewable energy include its low environmental impact, consistent availability even in challenging weather conditions, and its effectiveness in reducing pollution. Additionally, renewable energy contributes to economic growth, fosters job creation, and enhances energy security. However, there are challenges associated with renewable energy storage, which scientists are actively working to address. In addition, public opposition for the installation of renewable energy infrastructure also create difficulties. Increasing public education and awareness regarding the advantages of renewable energy can assist increasing the acceptability, which can further help policymakers in making well-informed decisions. This paper provides a comprehensive overview of diverse renewable energy sources and their current advancements in development. This review further finds that effective government policies aimed at reducing carbon emissions, coupled with improved technology and storage solutions, the adoption of renewable energy will expand significantly in the coming years.

“…The first term in the right-hand side of equation ( 4) is the electrostatic force due to free charges, the second term is the force associated with the non-uniformity of the permittivity on the gas liquid interface and the third term is the force due to electric field gradient. Charge on a bubble surface in an electric field could be solved in equation ( 5) [28]:…”

Electrical discharges in liquids with and without gas injection was experimentally studied with two circuits (RC and single spark gap). Electrical breakdown could be initiated from the following mechanisms: electrode initiation; impurity initiation; and Taylor cone driven initiation. Discharges initiated by electrodes were observed only with the single spark gap circuit. Impurities and Taylor cones can initiate discharges when using the RC circuit. With the single spark gap circuit, bubbles were nearly stationary in the gap before and during discharges because of the limited time to respond to the electric field growth (dV/dt = 1 kV ns −1 ). Bubbles and impurities gain significant energy and undergo significant dynamic changes with the RC circuit under a long rising time. Charge relaxation time on bubbles or impurities in the fluids were close to 100 ms, which is comparable with the circuit rising time. Bubble dynamics observed include reduced bubble size, increased bubble speed and shape change. Taylor cones were observed on bubble surface using a high-speed camera during multiple discharge events, and usually led to breakdown. Taylor cones develop on a bubble surface through multiple states over a period of 10-500 μs. State one was typically seen on a bubble surface with a sharp tip caused by the residual charge. A single streamer was initiated on the tip of the cone at state two. State three developed multiple bush-like streamers on the cone and usually triggered a breakdown in the gap. Discharge behaviors in liquids were also investigated with the RC circuit at different pulsing frequencies. At a low pulsing frequency (1 Hz), discharge events are independent from each other. When pulsed above 10 Hz, bubbles created in the gap accumulate and participate in the next discharge event. Bubble accumulation results in a cloud where local secondary discharges are observed with a much higher frequency up to a few kHz for several milliseconds.

“…Replacing high-temperature reactors and furnaces with plasma reactors using carbon-free electricity will significantly reduce CO 2 emissions [17][18][19]. Plasma technologies for refining heavy oils reduce the use of hydrogen and also exclude the use of expensive catalysts [20][21][22][23].…”

A pulsed plasma pyrolysis reactor with an efficient control system was designed for fuel oil processing. Non-thermal plasma pyrolysis was carried out in the liquid phase at low temperatures (not higher than 100 °C) in a 300 cm3 reactor without additional reagents or catalysts. The main process parameters and characteristics of non-thermal plasma fuel oil products were investigated within the DC source voltage range of 300–700 V. An increase in the energy of pulsed discharges led to an increase in the productivity of the plasma pyrolysis process and the yield of hydrogen but reduced the yield of acetylene and ethylene. The resulting gas consisted predominantly of hydrogen (46.5–50.0 mol%), acetylene (28.8–34.3 mol%), ethylene (7.6–8.6 mol%), methane (4.2–6.2 mol%), and C3–C5 hydrocarbons. The solid-phase products were in the form of disordered graphite and multilayer nanotubes.
