Hydrogen is a necessary element in the transition to sustainable energy systems and plays crucial role achieving net zero emission targets. However, current methods of hydrogen production are characterized by high carbon intensities. For instance, responsible for approximately 1.05 billion tons CO2 annually. This equates about 11 kg emitted per produced, significantly higher than many other industrial processes like ammonia, iron steel, methanol, ethylene, cement production. To address urgent need meet global decarbonization goals, it develop scale up low-carbon technologies, especially given significant emissions currently associated with existing methods. review investigates strategies decarbonizing steam methane reforming (SMR) process, exploring multiple pathways reduce its footprint. These approaches include SMR capture storage, electrolyzer, standalone electrification (e-SMR), improving efficiency within infrastructures. Additionally, alternative such as dry pyrolysis emerging techniques that utilize natural gas produce hydrogen, offering reductions compared traditional SMR. study presents comprehensive analysis production, valuable insights into this goal. It identifies key opportunities challenges commercializing these technologies provides strategic recommendations enhance their feasibility market adoption, which enhanced ongoing research development efforts. Achieving can be realized through integration utilization use low- or high-temperature electrolyzers, overall footprint unit short term. In medium long term, produced effectively via water electrolysis e-SMR. The offers pathway aligning environmental economic goals.

Microwave heating converts electromagnetic energy directly into thermal within the heated material, thereby overcoming limitations of traditional indirect heat transfer methods. However, microwaves are well-known to have limited penetration depth, which remains a significant challenge that inhibits use in processes requiring uniform heating. Here, we show fluidized beds particles with sufficient electrical conductivity break imposed by microwave enabling large-scale reactors. Results suggest alternating magnetic field penetrates entire studied reactor induce eddy currents everywhere, causing each particle be heated. The power absorption density for Geldart A and B across bed is uniform, no evidence exponential attenuation, introducing unexpected depth under component. Utilizing energy, sourced clean electricity, offers transformative solution decarbonize industry, significantly reducing greenhouse gas emissions.
