A virtual International Forum on Hydrogen Production Technologies (HyPT-2), was held from Sept 14-16, 2021.
Following on from the very successful Hydrogen Production Technologies (HyPT) Forum, which was held as a face-to-face event in 2019, the second international forum HyPT-2 was a virtual event, which continued to explore, in depth, a range of current and emerging zero carbon emission (CO2-free) hydrogen production technologies.
This forum presented an in-depth overview of a range of current and emerging zero carbon emission (CO2-free) hydrogen production technologies. The forum explored, through expert opinion and discussion, the different technologies, with emphasis on:
- Appraisal of current technologies, projections and limitations.
- Challenges and limitations of emerging technologies, and barriers leading to cost reduction
- Consideration of system integration, scale-up and effectiveness, as well as life-cycle analysis.
The HyPT-2 forum was sponsored by the Australian Renewable Energy Agency (ARENA) to support interactions with international Mission Innovation (MI) activities. The forum was organised by the Centre for Energy Technology at the University of Adelaide.
The forum was divided into the following 6 themed sessions:
- Large-scale electrolysers - limitations and future prospects
- Emerging electrolysis technology
- Hydrogen from natural gas
- Thermochemical processes
- Hydrogen from bioresources and waste
- Photo-electrochemical (PEC) and photocatalysis (PC)
Each technical session was focussed on a related class of technology. Extensive discussion time was allocated to address the following specific questions:
Can each of the technologies achieve hydrogen production that is internationally competitive over the current benchmark of electrolysis?
- What are the key challenges and limitations to the uptake of each technology (including technology development, upscaling, de-risking, resource and storage variability, cost trajectories and sensitivities)?
- What industry-specific or market-specific drivers exist for each of the technologies?
- What knowledge can be gained from exemplars or case studies in related industries?

Mitigating performance losses in scaling-up solar water splitting devices

Institute for Solar Fuels, Helmholtz-Zentrum Berlin für Materialien und Energie GmbH
Significant progress has been reported in solar water splitting, with solar-to-hydrogen (STH) efficiency as high as 30% already demonstrated. However, two major challenges remain. First, these high-efficiency devices (> 15%) have only been achieved using expensive and non-scalable III-V semiconductors. Low-cost metal-oxide based devices, mainly using BiVO4 as the absorber, have only achieved STH efficiency of < 10%. Due to stability limitations, many of these metal-oxide based devices are operated in near-neutral pH electrolytes, which poses an additional mass transport challenge. Second, the majority of the demonstrated devices are still at the laboratory scale. Reports on large-area devices are limited, and they typically show much lower efficiencies. This is best illustrated in a recent review: even when III-V semiconductor-based devices are considered, there is no report of devices with a semiconductor absorber area larger than 10 cm2 and STH efficiency > 10%. In this talk, we will discuss the scale-up of our photoelectrochemical water splitting devices based on a complex metal oxide absorber. Factors other than the semiconductor itself are found to be responsible for a total voltage loss of > 500 mV and therefore limit the overall performance of the large-area device. We use a combination of multiphase multiphysics simulations (2-D and 3-D finite element analysis models) and validation experiments (e.g., in-situ pH fluorescence, particle image velocimetry, shadowgraphy) to quantify and breakdown the different loss mechanisms (substrate and electrolyte Ohmic loss, concentration overpotentials, product crossover, bubble-related losses) while scaling-up photoelectrochemical water splitting devices.[3-6] Based on these insights, electrochemical engineering strategies to overcome the scale-up related losses are offered.

Photocatalytic water splitting for a large scale solar hydrogen production
Overall water splitting using particulate photocatalysts has been attracting attention as a means of large-scale renewable solar hydrogen production . The author’s group has studied various semiconductor oxides, (oxy)nitrides, and (oxy)chalcogenides as photocatalysts. The apparent quantum yield of overall water splitting using the SrTiO3 photocatalyst has been improved to 95% in the near-ultraviolet region by refining the photocatalyst and cocatalyst preparation (Fig. 1) . This quantum efficiency is the highest ever reported, indicating that particulate photocatalysts can drive the uphill overall water splitting reaction as efficiently as the photon-to-chemical conversion process in photosynthesis. In addition, the author's group has also been developing panel reactors for large-scale applications . A solar hydrogen production system with a light-receiving area of 100 m2 was recently built (Fig. 2), and its performance and system characteristics including safety issues have been examined .
For practical solar energy harvesting, it is essential to develop photocatalysts that are active under visible light irradiation. Ta3N5 and Y2Ti2O5S2 photocatalysts are active in overall water splitting via one-step excitation under visible light irradiation [5.6]. Particulate photocatalyst sheets efficiently split water into hydrogen and oxygen via two-step excitation, referred to as Z-scheme, regardless of size. In particular, a photocatalyst sheet consisting of La- and Rh-codoped SrTiO3 and Mo-doped BiVO4 splits water into hydrogen and oxygen via the Z-scheme, showing a solar-to-hydrogen energy conversion efficiency exceeding 1.0% [7,8]. Some other (oxy)chalcogenides and (oxy)nitrides with long absorption edge wavelengths can also be applied to Z-schematic photocatalyst sheets.
In my talk, the latest progress in the development of photocatalytic materials and their reaction systems will be presented.

E-TAC - efficient and economical decoupled water splitting
Green hydrogen production by coupling renewable energy sources with electrolysis is a promising route for major energy transition, reaching zero carbon emissions and mitigating climate change. Renewable power generation is already cost effective and widely available. On the other hand, electrolysis still faces significant technological challenges to improve efficiency and reduce manufacturing costs. In conventional electrolysis, the oxygen evolution reaction (OER) is a four-electron oxygen reaction which requires a considerable overpotential, leading to energy waste in the form of heat. In addition, hydrogen and oxygen are produced simultaneously in close proximity, hence a complex stack design which includes separator/membrane and sophisticated sealing are required to prevent mixing and mitigate explosion risk. The high complexity and low efficiency lead to costly hydrogen production. E-TAC (Electrochemical – Thermally activated chemical) water splitting technology holds great promise in overcoming these challenges, providing a path for low-cost green hydrogen production. H2Pro is a startup company with a clear vision of using E-TAC technology to enable 1$ per kilogram of hydrogen by 2030.

Challenges and Opportunities in Bringing New Chemistry to Produce Hydrogen to Market
So-called “turquoise” hydrogen promises inexpensive hydrogen by direct decomposition of natural gas to hydrogen and solid carbon. The basic methodology has been around for many decades – one either uses extremely high temperatures to drive thermodynamically efficient pyrolysis, or one uses catalysts at lower temperature. At Johns Hopkins, in collaboration with ETCH, INC (a Johns Hopkins University-affiliated startup), Southern Company, and Cabot Corporation through a US DOE ARPA-E funded program, we have been exploring the first fundamentally new chemical approach to methane decomposition discovered in a long time. In our system, we employ a chemical cycle in which methane is used to reduce a metal chloride salt at moderately high temperatures to metal, hydrogen chloride, and solid carbon. When the temperature of the reactants drop, hydrogen chloride back-reacts with the metal to regenerate the chloride salt and produce hydrogen. It is a chemical cycle in which methane enters, solid carbon and hydrogen leave, and for which the net energy input equals the formation energy of methane. The cycle has the advantage of very high methane decomposition conversion rates and efficiencies. While overcoming many of the challenges in current methane decomposition technologies, new issues in implementation have inevitably arisen. In this context, we will discuss the challenges and imperatives of bringing new hydrogen production chemistry to market.

Modeling and demonstration of a scaled photo-electrochemical co-generation system
Solar energy is the most abundant renewable energy resource and is versatile enough to be converted to heat and electricity, or to drive photo-, thermal-, and/or electrochemical processes (or combinations thereof).
We have developed a thermally integrated photo-electrochemical water splitting device and process, which we have demonstrated at the 30 W lab-scale and subsequently scaled to a ~20 kW demonstrator-scale system. I will review the lab-scale device design process, which incorporated the development of complex transient multi-dimensional models, and highlight some performance metrics in the experimental demonstration under controlled conditions. I will then discuss our approach to scaling the device towards a system that includes tailored auxiliary components. I will show our modeling activities for the scaled system, helping to understand the coupled system dynamics, as well as design decision and demonstration activities. I will review the performance of the system operated on-sun, under varying operational conditions (for example, summer vs. winter) and highlight how this system best be operated as co-generation system. Finally, I will show that the same design approaches can also be used for other chemical reactions, such as photo-electrochemical CO2 reduction.

Technology and Applications of SOEC Electrolysis
With its roadmap for moving to a competitive low-carbon economy in 2050, the European Commission sets greenhouse gas emissions targets for different economic sectors. To achieve international energy and climate policy goals, renewable molecules are required for the replacement of today’s used fossil resources. Using a Solid Oxide Electrolyser Cell (SOEC), Sunfire offers the opportunity to use green electricity as a renewable feedstock for industry and mobility.
Electrolysers based on SOEC are an upcoming technology which are not as mature as the low-temperature counterparts. Nevertheless, due to its outstanding high efficiency and capability of producing syngas via a co-electrolysis of steam and CO2, the SOEC has a very high economic potential if steam or waste heat are available. With a couple of large-scale demonstration projects for both pure steam- and co-electrolysis, Sunfire performs pioneering work in the field of high-temperature electrolysis.
The presentation will provide an overview on the technical background of SOEC, its development status and will summarize the most promising applications. Here, three sectors are addressed, where Sunfire electrolysers are installed. This comprises iron & steel work with the target of replacing blast furnaces by Direct Reduced Iron (DRI process) with hydrogen as reduction agent, the shift form fossil to renewable hydrogen in refineries and finally the generation of renewable fuels (e-Fuel) using the Power-to-Liquid technology.

The Technical and Economic Potential of Hydrogen within the United States
Hydrogen markets have an opportunity to grow as its value as an energy intermediate increases. Hydrogen’s estimated serviceable consumption potential in the United States is 106 MMT/yr which is a ten-fold increase over the current market size. That opportunity is driven primarily by increased demands for metals refining, biofuel and hydrocarbon production, supplementing the natural gas system, seasonal storage for the electricity grid, and fuel cell electric vehicles. The U.S. has many renewable, nuclear, and fossil resources that each could meet that demand itself. The economic potential, which considers both costs to produce hydrogen and willingness of applications to pay for it, is 22 to 41 MMT/yr. The range is impacted by factors that impact the cost to produce including the price of natural gas and the cost of electrolyzers. It is also impacted by competition to provide the same services as hydrogen including electrification.

Progress on sulfur cycles
Sulfur based thermochemical cycles were developed to store nuclear energy in hydrogen in the 1970s and 1980s. Because of low energy prices they were never industrially realized. Today CO2 emission free processes are sought-after not only to store energy but to operate industrial processes. Therefore, sulfur cycles are even more interesting than 40 years ago as they can be integrated into minerals and metals processing where sulfur is available. They can be operated by concentrated solar energy that will provide the necessary heat at about 850 °C. The presentation will give an update on the available reactor technology and on the analysis how a solar heated sulfur cycle can be coupled to an ore processing facility efficiently. An outlook will be given on the next development steps and on how to implement the technology in industry.

Redox-Active Metal Oxide Materials and Reactor: Thermochemical Water Splitting Cycle
High temperature endothermic reduction of redox-active metal oxides that can exchange oxygen between the solid and the gas phase at achievable conditions (where what is achievable remains an open question for the field), converts thermal energy to stored chemical energy. A subsequent re-oxidation step either recovers the stored energy as heat or utilizes it to drive other chemical reactions. If the re-oxidation step restores the material to its original state so that the two-steps can repeat indefinitely, the sequence of reactions constitutes a thermochemical cycle. Two related processes (reversibly re-oxidizing with oxygen or affecting bond breaking by re-oxidizing with CO2 and/or water) are somewhat analogous; the production of energized carriers (H2 and/or CO) is significantly more constrained by thermodynamics and hence subject to greater challenges for achieving high efficiency and low cost.
This presentation will discuss new revelations in the thermodynamics, operating conditions, and reactor design for the redox-active metal oxide water splitting cycle.

Hydrogen production from microalgae via reactive flash volatilisation
Meeting the increasing global energy demand while transiting to net zero carbon emission one of the grand challenges of this century. Hydrogen is widely regarded as a potential solution. However, at present, 96% of the H2 is produced from fossil fuels. Hydrogen production from bioresources and waste is a viable alternative. Microalgae is one of the leading candidates to produce renewable hydrogen due to its ability to grow in brackish water, high CO2 uptake and fast growth cycle. However, dewatering and char and tar accumulation during gasification limits its industrial application. Here we propose a solution in which catalytic reactive flash volatilisation (RFV) eliminates the need for dewatering and results in tar free syngas.
In this work, catalytic RFV of microalgae (Scenedesmus sp.) was performed using steam as a gasifying agent to produce hydrogen-rich syngas. Scenedesmus sp. was selected due to its high CO2 tolerance.
In the presence of Ni-Rh/Al2O3 catalyst at 650°C and Carbon to Steam ratio of 0.12, H2 rich (65% (v/v)) syngas was generated. Gasification efficiency of 85% was achieved without tar formation.
A detailed ASPEN Plus® flowsheet model was developed to perform technoeconomic and life cycle assessments of hydrogen production. A plant located in India, processing 12790 kg/h of microalgae to produce 1350 kg/h of H2 was considered. The results indicated that a payback period of 3.78 years, with 22% IRR was achievable at the current hydrogen price of $10/kg. The life cycle climate change impact was 7.56 kg CO2-eq./kg H2, which was lower than the current processes.

Green Hydrogen Demand Skyrocketing: A Gigawatt-scale Electrolyzer Market in 2022
Manufacturers shipped a record 200 megawatts (MW) of electrolyzers in 2020, 55-60% of which went to low-carbon applications. BNEF expects shipments to double in 2021 and potentially more than quadruple in 2022, driven by demand from industries eager to cut emissions. The year 2022 should see shipments of 1.8-2.5 gigawatts (GW), with China accounting for 60-63% of global installations. Alkaline electrolyzers are to dominate the market due to better economics, holding an 80% share of shipments in 2022. At least 5GW of annual electrolyzer manufacturing capacity should come online by the end of 2021 and 10GW by the end of 2022, corresponding a significant overcapacity. Rising demand for green hydrogen also attracted the attention of some leading Chinese solar companies. The world’s biggest module provider and the second-largest inverter firm are already building new factories to make electrolyzers, which together will have at least 2.5GW of manufacturing capacity commissioned by 2022.
Dr Nigel Williamson, Clean Power Hydrogen Group (CPH2), UK
Dr Nigel Williamson is Co-founder and Technology Director for Clean Power Hydrogen Group Ltd (CPH2) located in Doncaster, UK. Dr Williamson developed membrane-free electrolyser technology and helped to build a 30-strong team of engineers, scientists, administrators and marketing experts, developing world markets for CPH2 technology electrolysers. He has registered numerous patents and patent applications world-wide relating to electrolyser and peripheral technologies.
CPH2 technology is designed around sustainability, using no membranes and no precious platinum-group metal (PGM) catalysts. The system is 95% recyclable or reusable, including the stack, scalable from home refueller to gigawatt scale, and is designed for a 25-year lifetime.
As founder and majority owner of NWD International, Dr Williamson developed leak-free sealing technologies and markets for aerospace, automotive, construction and agricultural equipment manufacturers, which contributed to the elimination of hydrocarbon leaks to the environment. He developed sealing systems for high-pressure hydrogen and other fuel gases and worked with NASA, General Dynamics, Lockheed, Boeing and other automotive industry clients and customers to overcome long-standing sealing problems.
As Managing Director of Pilot Industries, a fuel system manufacturer for European automotive industry customers, Dr Williamson designed, installed and commissioned Europe's largest protective metals coating line.
As Chief Engineer with ITM Power, he established a team of engineers to develop PEM electrolyser systems, resulting in their existing electrolyser technology production.
Why use membrane-free electrolyser technology?
Without a membrane, there is significantly less resistance to ion transfer, requiring no precious metal catalysis to drive the reaction. The technology is made from readily available, ubiquitous materials, which provide an equivalent performance without the need for expensive metal catalysts. Performance does not degrade over time, and materials are 98% recyclable or reusable, as well as being easy to manufacture, with no clean-room assembly required. The CPH2 technology can be licensed for manufacture, where demand is highest, thereby removing production and shipping bottle-necks. The simplicity of the system allows for maintenance by relatively low-skilled technicians. In addition, water supply quality can be relaxed to ‘potable’ standards, and gases are separated by cryogenic (oxygen distillation) technology, which is made super-efficient by use of a 3-stream heat exchanger.
