Hydrogen is an essential material/fuel for industry and energy conversion. The processes for producing hydrogen depend on the raw materials and energy source used. In terms of climate impacts, the most promising hydrogen production method is water electrolysis. The regenerative electrolysis process depends on the carbon intensity of the electricity and the efficiency of converting that electricity into hydrogen. The development of technologies to extract hydrogen (from conventional and renewable resources) tends to optimise the water electrolysis process using renewable energies by extending material durability, increasing performance efficiency, and reducing precious metal contents in catalysts, thereby lowering the production costs. The article introduces the latest advances in green hydrogen production technologies using renewable energies, particularly focusing on water and seawater electrolysis, combining electrolysis and solar energy as well as hydrogen-based synthetic fuel production, hydrogen production from biomass and biogas.

Hydrogen is an environmentally friendly biofuel which, if widely used, could reduce atmospheric carbon dioxide emissions. The main barrier to the widespread use of hydrogen for power generation is the lack of technologically feasible and—more importantly—cost-effective methods of production and storage. So far, hydrogen has been produced using thermochemical methods (such as gasification, pyrolysis or water electrolysis) and biological methods (most of which involve anaerobic digestion and photofermentation), with conventional fuels, waste or dedicated crop biomass used as a feedstock. Microalgae possess very high photosynthetic efficiency, can rapidly build biomass, and possess other beneficial properties, which is why they are considered to be one of the strongest contenders among biohydrogen production technologies. This review gives an account of present knowledge on microalgal hydrogen production and compares it with the other available biofuel production technologies.

The goal of the US Department of Energy (DOE) hydrogen production portfolio is to research and develop low-cost, highly efficient and environmentally friendly production technologies based on diverse, domestic resources. The DOE Hydrogen Program integrates basic and applied research, as well as technology development and demonstration, to adequately address a diverse range of technologies and feedstocks. The program encompasses a broad spectrum of coordinated activities within the DOE Offices of Energy Efficiency and Renewable Energy (EERE), Nuclear Energy (NE), Fossil Energy (FE), and Science (SC). Hydrogen can be produced in small, medium, and larger scale facilities, with small-scale distributed facilities producing from 100 to 1,500 kilograms (kg) of hydrogen per day at fueling stations, and medium-scale (also known as semi-central or city-gate) facilities producing from 1,500 to 50,000 kg per day on the outskirts of cities. The largest central facilities would produce more than 50,000 kg of hydrogen per day. Specific technologies currently under program development for distributed hydrogen production include bio-derived renewable liquids and water electrolysis. Centralized renewable production pathways under development include water electrolysis integrated with renewable power (e.g., wind, solar, hydroelectric, or geothermal), biomass gasification, solar-driven high-temperature thermochemical water splitting, direct photoelectrochemical water splitting, and biological production methods using algal/bacterial processes. To facilitate commercialization of hydrogen production via these various technology pathways in the near and long terms, a “Hydrogen Production Roadmap” has been developed which identifies the key challenges and high-priority research and development needs associated with each technology. The aim is to foster research that will lead to hydrogen production with near-zero net greenhouse gas emissions, using renewable energy sources, nuclear energy, and/or coal (with carbon capture and storage). This paper describes the research and development needs and activities by various DOE offices to address the key challenges in the portfolio of hydrogen production technologies.

The development of methods for the complete and complex processing of raw food materials is one of the main ways to achieve the efficiency of its use: reduce production costs, expand products range and increase products demand. Over the last years, growing attention is paid to the search and development of new technologies of the processing of non-traditional and underutilized types of food materials, such as meat and by-products from alternative animal species. The research was aimed at studying the influence of the marinating process on the quality of the newly developed food product. The object of research was the tongue of domesticated reindeer, the underutilized raw materials of the Kola Peninsula. Product samples were taken in 2012-2016 on the basis of the agricultural production cooperative ”Tundra”, research was carried out on the basis of the Department of Food Production Technologies of the Federal State Budgetary Educational Institution of Higher Education ”Murmansk State Technical University”. The effects of marinating and duration of heat treatment on the quality of the product samples was studied. The parameters characterizing the generalized indicator of quality were selected - organoleptic (appearance, flavor and taste), physical (cutting force) and microbiological. The optimal composition of the marinade is proposed. The technology of culinary processing of the domesticated reindeer tongue was optimized.

The main purpose of the pretreatment of straw raw materials which used to produce hydrogen is to remove lignin and hemicellulose, reduce the degree of crystallinity of cellulose, as well as improve the porosity of the matrix is the key technology of cellulose into hydrogen,which designed to improve the materials, low the production costs. This paper mainly studies how to process the optimization that used Straw biomass of raw materials which pretreated with acetic acid to hydrogen production. To optimize the process of pretreatment of acetic acid. separat the rate of sugar yield as the ability of straw biomass of raw materials to product hydrogen, The results show that: when the particle size of the agriculture as a straw is straw with 25% acetic acid used and the solid-liquid ratio is 1:20, to pretreat 30min at 121 °C, can get the highest sugar rate.

Hydrogen energy is becoming more and more blooming because of its diversified sources, eco-friendly and green, easy storage and transportation, high-efficient utilization, etc. The use of hydrogen as an energy carrier is expected to grow over the next decades. Hydrogen, like electricity, is a secondary energy. Hydrogen production is the foundation for all kinds of applications. Based on the resources situation in China, potential of hydrogen production is analysed. China has a large potential of hydrogen production from coal, which is about 2.438 billion tons. Potential of hydrogen production from natural gas is less than that from coal, which is about 501 million tons. According to the average consumption of methanol per year, potential of hydrogen production from methanol is about 690, 000 tons per year. Potential of hydrogen production from industrial gas (coking, petrochemical and chlor-alkali industries) is about 866, 400 tons per year. Potential of hydrogen production from abandoned renewable energy power is about 1798.2 million tons per year. Distribution of resources in China differs among provinces. The deployment of hydrogen industry should pay attention to local hydrogen production potential. A green hydrogen production method, such as water electrolysis by renewable energy power, is a promising and environmental friendly way.
