An Overview of Hydrogen Production from Renewable Sources and Its Main Applications
Summary
This review provides an overview of hydrogen production methods from renewable sources and their main technological applications in energy generation and organic synthesis. Researchers discuss alternatives to fossil fuel dependence, noting that fossil fuels currently supply about 87% of global energy demand. The study highlights hydrogen as a key component of a sustainable energy future, addressing multiple dimensions of sustainability beyond just greenhouse gas emissions.
Abstract There is a misconception that sustainability is only related to greenhouse gas emissions into the atmosphere, and that this is the only risk to which the planet is exposed. Sustainability is a multidimensional concept and must advance simoutaneously on several fronts, such as the urgent need to increase energy, clean water, clean air, food, mobility, health, and poverty reduction. All the problems of these multi‐dimensions are aggravated by the continuous growth of the world population, mainly in economic and socio‐environmental issues. However, the biggest challenge is to increase the supply of clean energy from renewable sources, as all other dimensions of sustainability depend on energy supply and policy decisions. The consumption of fossil fuels has supplied the current energy demand by approximately 87 %. Still, there are predictions of depletion, and the effects caused on the environment by the production of greenhouse gases bring significant economic losses. In this review, we will address the most common methods for hydrogen production, as well as its main technological applications in organic synthesis and for energy generation.

Hydrogen from Waste Gasification
This review examines how gasification technology can convert waste materials, including municipal solid waste, tires, and plastic waste, into hydrogen fuel. Researchers found that hydrogen production potential varies widely depending on the feedstock, ranging from 15 to 300 grams of hydrogen per kilogram of waste. The study highlights gasification as a promising pathway for producing renewable hydrogen, though supportive regulations are needed to bring the technology to market.
Sustainable-green hydrogen production through integrating electrolysis, water treatment and solar energy
Researchers evaluated the feasibility of producing green hydrogen by integrating electrolysis with solar energy and treated sewage water instead of purified water. They found that solar-powered systems reduced CO2 emissions by approximately 88% compared to grid electricity, though capital costs were significantly higher. The study suggests that the process could become economically sustainable if hydrogen production costs fall to around two dollars per kilogram.
