Special Issue Information

Dear Colleagues,

Climate change is one of the critical challenges of the 21st Century. Combustion of fossil fuels are the main source of greenhouse gases (GHGs). At present, hydrogen is produced primarily from catalytic steam methane reforming (SRM) and coal gasification processes. Both of these processes lead to GHG emissions. Zero-carbon hydrogen is observed as a promising fuel to decarbonize energy, transportation, industry, and agricultural sectors which account for more than 80% of the global GHG emissions. To meet the rising demands of global hydrogen economy, the emphasis has been on producing carbon-neutral or carbon-negative hydrogen at a low cost.

The carbon-neutral or carbon-negative hydrogen production pathways are in the early stages of development. The potential pathways are thermochemical conversion of waste, such as biomass, coal, MSW, and plastics waste, electrochemical water splitting, and microbial fermentation of biomass.

The overall focus of this Special Issue is zero-carbon and low-cost hydrogen production for decarbonizing energy, transportation, power, and agricultural sectors. The scope mainly includes hydrogen production through gasification of biomass and waste resources, electrochemical water splitting, and microbial fermentation of biomass.

This Special Issue is looking to publish review, experimental, modeling, and simulation research papers on the following topics:

  1. Gasification of waste resources;
  2. Co-gasification of coal and biomass;
  3. Proton Exchange Membrane Water Electrolysis;
  4. Alkaline and Anion-Exchange Membrane Water Electrolysis;
  5. Solid Oxide Water Electrolysis;
  6. Photoelectrochemical Water Splitting.

This research studies the current state of the Colombian industrial sector, which is focused on self-generation processes. The study’s objective is to search for viable technological strategies that strengthen this particular sector’s competitiveness and sustainable development. The analysis shows that internal combustion engines represent 49% of the technologies used for self-generation. The main fuel used in the sector is natural gas, with a percentage of 56%. The lack of strategies for the use of residual heat and technological inefficiencies caused a loss of 36% in the energy used in the Colombian industrial sector. Thermoelectric generators are a feasible way to recover energy from exhaust gases in engines used for self-generation. Additionally, they allow a 4% reduction in fuel consumption and an improvement in the engine’s energy efficiency. The use of hydrogen as fuel allows a 30% reduction in polluting emissions, such as CO2, CO, HC, and particulate matter. Hydrogen production processes, such as water electrolysis, allow the participation of Colombia’s solar energy potential, leading to sustainable hydrogen production, efficiency (60–80%), and a lower economic cost. In general, the application of thermoelectric generators and the use of hydrogen gas allow the improvement of the Colombian industrial sector’s environmental, social, and economic aspects due to greater competitiveness and the reduction in emissions and operating costs.

Hydrogen is a source of clean energy as it can produce electricity and heat with water as a by-product and no carbon content is emitted when hydrogen is used as burning fuel in a fuel cell. Hydrogen is a potential energy carrier and powerful fuel as it has high flammability, fast flame speed, no carbon content, and no emission of pollutants. Hydrogen production is possible through different technologies by utilizing several feedstock materials, but the main concern in recent years is to reduce the emission of carbon dioxide and other greenhouse gases from energy sectors. Hydrogen production by thermochemical conversion of biomass and greenhouse gases has achieved much attention as researchers have developed several novel thermochemical methods which can be operated with low cost and high efficiency in an environmentally friendly way. This review explained the novel technologies which are being developed for thermochemical hydrogen production with minimum or zero carbon emission. The main concern of this paper was to review the advancements in hydrogen production technologies and to discuss different novel catalysts and novel CO2-absorbent materials which can enhance the hydrogen production rate with zero carbon emission. Recent developments in thermochemical hydrogen production technologies were discussed in this paper. Biomass gasification and pyrolysis, steam methane reforming, and thermal plasma are promising thermochemical processes which can be further enhanced by using catalysts and sorbents. This paper also reviewed the developments and influences of different catalysts and sorbents to understand their suitability for continuous clean industrial hydrogen production. Full article
