Hydrogen is the most abundant gas in the universe and is classified by the World Energy Organization as the cleanest fuel in the world compared to other energy products. Therefore, the hope hangs upon it in achieving the zero fuel emissions strategy, which adopted by the largest countries in the world. Also, it is believed that by 2050, hydrogen consumption will represent 24 % of the global energy sector, with investments estimated at 2.5 trillion dollars, compared to only 139 billion dollars at present. There are three types of hydrogen (gray, blue and green) classified based on their production methods and carbon content. Gray hydrogen is usually produced by burning natural gas at high temperatures and once the carbon is removed or captured, the gray hydrogen turns into blue hydrogen. As for green hydrogen with zero emissions, it is produced through the electrolysis of water or by using renewable energy sources such as solar cell, wind energy, etc. to avoid any emissions during the production stages. Despite the efficiency of green hydrogen compared to other types, its price remains a major obstacle in the promotion and marketing, which is estimated at 3.5 Euro/kg, compared to 1.5 Euro/kg for blue hydrogen. In addition to some other obstacles related to infrastructure and raw materials used in the production stages. Recently, and in order to remove all these obstacles, the leading countries in the energy sector pumped more investments to study all these obstacles and assess the current hydrogen market, which in turn leads to the acceleration of the upscaling of hydrogen production. In this context, this research was developed to study all these current and future challenges. In addition to discussing the traditional and modern methods of its production. Besides taking a look at the projects under implementation in this regard.

“…Appropriate addition of Na 2 HPO 4 can promote the synthesis of NADPH by providing essential phosphorus, thereby improving the yield and production efficiency of PHB. In addition, the appropriate addition of Na 2 HPO 4 will promote the synthesis of ATP, which improves the uptake efficiency of the carbon source, thereby increasing the efficiency of PHB synthesis (Lai and Lan 2021).…”

The effects of NaCl, Na2SO4, Na2HPO4, and Na3C6H5O7 on the production of 3-hydroxybutyrate, polyhydroxybutyrate, and by-products by Burkholderia cepacia. Proper addition of Na3C6H5O7 can significantly promote the production of 3-hydroxybutyric acid and polyhydroxybutyrate. The concentration, productivity, and yield of 3-hydroxybutyrate were increased by 48.2%, 55.6%, and 48.3% at 16 mM Na3C6H5O7. The increases of 80.1%, 47.1%, and 80.0% in the concentration, productivity, and yield of polyhydroxybutyrate were observed at 12 mM Na3C6H5O7. Na2SO4 and Na2HPO4 also have positive effects on the production capacity of 3-hydroxybutyrate and polyhydroxybutyrate within a certain range of concentration. NaCl is not conducive to the improvement of fermentation efficiency. Compared with a single nitrogen source, a mixed nitrogen source is more conducive to enhancing the production of 3-hydroxybutyrate and polyhydroxybutyrate.

“…Anaerobic digestion is a biochemical process that converts biogenic waste/wastewater to sustainable energy (biogas/bio-methane) and nutrients (biofertilizer) [7][8][9]. It has been found that 12 out of the 17 sustainable development goals (SDGs) are directly influenced and contributed to by biogas, as biogas can potentially boost renewable energy, reduce waste, improve waste management, significantly replace natural gas imports and generate employment [10].…”

Waste-Derived Renewable Hydrogen and Methane: Towards a Potential Energy Transition Solution

Anaerobic digestion (AD) is an environmentally friendly process for recovering low-carbon energy from the breakdown of organic substrates. In recent years, AD has undergone a major paradigm shift, and now the technology is not only considered as a “waste treatment” method and is instead viewed as a key enabler of the future “circular economy” with its potential for resource recovery (low-carbon energy, safe water, and nutrients). Currently, waste-derived biogas from AD is the most affordable and scalable source of renewable energy. Biomethane (upgraded biogas) can serve as a significant renewable and dispatchable energy source for combating the problem of global warming. Acidogenesis, an intermediate step of AD, can produce molecular hydrogen (H2) along with green chemicals/platform chemicals. The use of low-carbon hydrogen as a clean energy source is on the rise throughout the world, and is currently considered a potential alternative energy source that can contribute to the transition to a carbon-neutral future. In order to determine the future trade routes for hydrogen, nations are developing hydrogen policies, and various agreements. Hydrogen produced by biological routes has been found to be suitable due to its potential as a green energy source that is carbon neutral for the developing “Hydrogen Economy”. Recently, hydrogen blended with methane to a specific proportion and known as biohythane/hydrogen-enriched compressed natural gas (HCNG) has emerged as a promising clean fuel that can substantially contribute to an integrated net-zero energy system. This review provides an overview of the current state of fermentative hydrogen and methane production from biogenic waste/wastewater in a biorefinery approach and its utilization in the context of energy transition. The limitations and economic viability of the process, which are crucial challenges associated with biohydrogen/biomethane production, are discussed, along with its utilization.
