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 Advanced Hydrogasification Process (AHP) is being developed at Arizona Public Service (APS) to utilize the America’s abundant western coal supply to address concerns of diminishing domestic oil and natural gas resources as energy providers, while also incorporating a renewable energy and reducing greenhouse gas emissions. The AHP utilizes coal as a source for carbon, and hydrogen produced by renewable energy in the hydrogasification process to produce substitute natural gas (SNG) that can be fed to existing natural gas pipeline. The hydrogen will be produced through water electrolysis using wind firmed with off peak nuclear/coal electricity. The CO2 produced from the process will be recycled through biological approach — algae farming. With water and sun, algae will convert CO2 into starch, protein and lipids by photosynthesis.

Basic Production

The way to decarbonization will be characterized by the huge production of hydrogen through sustainable routes. Thus, the basic production way is water electrolysis sustained by renewable energy sources allowing for obtaining “green hydrogen”. The present paper reviews the main available technologies for the water electrolysis finalized to the hydrogen production. We describe the fundamental of water electrolysis and the problems related to purification and/or desalinization of water before electrolysis. As a matter of fact, we describe the energy efficiency issues with particular attention to the potential application in the steel industry. The fundamental aspects related to the choice of high-temperature or low-temperature technologies are analyzed.

Electrolysis Process

The purpose of this paper is to evaluate the performance of a prototype vehicle that uses a reversible fuel cell capable of producing and storing hydrogen and oxygen by breaking the water molecule - the electrolysis process, made possible with the use of solar panels. The vehicle shown only uses two main sources of energy: solar and hydrogen cells, both clean and renewable energy sources. Water is the only residue generated. The Fuzzy Logic was used in the establishment of linguistic variables and on the composition of inference rules based on power, solar panel area and solar irradiation. The Fuzzy Logic provides a method of translating verbal, vague, imprecise and qualitative expressions, common in human communication in numeric values. This enables the conversion of the human experience in a way understandable by computers. Thus, the technology made possible by the fuzzy approach has a practical value. In view of the severe environmental degradation in which the planet is going through and the scarcity of energy sources, especially fossil fuels, one of the great challenges of the scientific community is to develop new technologies that use clean and renewable energy sources, that are economically viable and promote sustainable technologies and processes.

Road Freight

By considering the weight penalty of batteries on payload and total vehicle weight, this paper shows that almost all forms of land-based transport may be served by battery electric vehicles (BEV) with acceptable cost and driving range. Only long-distance road freight is unsuitable for battery electrification. The paper models the future Indian electricity grid supplied entirely by low-carbon forms of generation to quantify the additional solar PV power required to supply energy for transport. Hydrogen produced by water electrolysis for use as a fuel for road freight provides an inter-seasonal energy store that accommodates variations in renewable energy supply. The advantages and disadvantages are considered of midday electric vehicle charging vs. overnight charging considering the temporal variations in supply of renewable energy and demand for transport services. There appears to be little to choose between these two options in terms of total system costs. The result is an energy scenario for decarbonized surface transport in India, based on renewable energy, that is possible, realistically achievable, and affordable in a time frame of year 2050.
