Griffith University researchers have reported a breakthrough in clean hydrogen electrolysis using CoSe₂ nanobelts, ultrathin sheets made out of a lattice of cobalt (Co) and selenium (Se), as highly-efficient water splitting electrocatalysts. To fully unleash the power of CoSe₂ nanobelts as an electrocatalyst for the oxidation or breakdown of water, the researchers have combined two separate processes.

In a paper published in Nature Communications, the Griffith University researchers describe how they have implemented both ‘Iron (Fe) doping’, replacing some of the cobalt on the nanobelt with iron, and ‘Cobalt (Co) vacancy’, removing some of the cobalt. When applied individually, the two processes improve the nanobelt’s ability to speed up reactions to a small degree but put together their combined effect dramatically increases catalytic activity.

The new Renewable Hydrogen Market Report, produced by ANT Energy Solutions and backed by the Australian Renewable Energy Agency (ARENA), features a number of key findings in the race to develop an Australian renewable hydrogen economy. The main conclusion is that on-site solar is the only way to go.

The report’s authors ran two models for renewable hydrogen produced by electrolysis, The first is a high OPEX, low CAPEX model (grid-connected, high capacity-factor), while the second is a high CAPEX, low OPEX model (behind-the-meter, low capacity-factor). The analysis indicated “that despite the much lower utilization rate, behind-the-meter solar renewable hydrogen generation can produce hydrogen at approximately half the cost per kilogram to a grid-connected system” with an electricity cost of AU$0.11 (US$0.07) per kilowatt-hour.

What this means is that the most cost-effective way of producing renewable hydrogen is by powering an electrolyzer with on-site solar. Indeed, the report suggests that hydrogen can be produced via on-site solar at a cost of $3.19 per kilogram of hydrogen versus $6.08 if produced from the grid.

Of course, considering that the costs of solar continue to decrease as efficiency rises, the cost of behind-the-meter solar hydrogen will only continue to drop, possibly below the AU$2 mark.

“Based on this alone, Australia has great potential to drive forward an increase in renewable energy and renewable hydrogen production,” the authors of the report said. “The impetus from ARENA is continuing to drive the cost of solar down with a continued reduction in the cost of large scale solar expected over the next five to 10 years.”

The call then, is for states and the federal government to support large-scale solar electrolysis as the cleanest and most obvious way to drive down the capital costs of a hydrogen economy.

Economic ecosystem

On-site solar is the most cost-effective way to build a domestic and export hydrogen industry, but it also might be the only way. “Commercialization of hydrogen as an end product requires the development of an entire economic ecosystem,” according to the report. “As with all ecosystems, they cannot function until there is critical mass in the system, so the faster scale can be developed, the more chance there is for the ecosystem to form and advantage to be generated.”

If Australia doesn’t act on its competitive advantage sooner rather than later, other countries might develop their hydrogen economies and start exporting first. The report points to Australia’s solar panel industry as an example of “where Australia failed to develop this ecosystem and competitive advantage has been lost to China and the United States, where scale of development has occurred in technology research, equipment design and fabrication.”

Businesses have already noticed the obvious competitive advantage. Toyota is installing a solar-electrolyzer at its site in Melbourne. Indeed, the company recently celebrated Earth Day by unveiling the first completed stage of its green hydrogen hub, with the help of ARENA funding.

Export potential

The CSIRO National Hydrogen Roadmap expects demand for hydrogen imports by Asian nations to reach 3.8 million tons by 2030. At the same time, ACIL Allen Opportunities for Hydrogen Exports model suggests that 10% to 20% of Japanese and South Korean hydrogen demand could be met by Australian exports. In other words, hydrogen means big business.

However, before we can talk about how much hydrogen countries such as Japan and Korea might want from us – let alone how we’ll manage to get the hydrogen up there – we must first decide how we’re going to produce said hydrogen.

In November, the COAG Energy Council adopted the National Hydrogen Strategy, our pathway to a domestic and export hydrogen economy. The strategy, however, remains “technology-neutral,” which is to say it is not solely to produce green hydrogen, but to keep Australia’s options open to fossil-fuels as well — playing the field, as it were. Although, as the ANT report shows, fossil-fuel-produced hydrogen is rather senseless compared to renewably produced hydrogen. Energy Minister Angus Taylor may think he is playing the field, but these are Flanders Fields, not Elysian ones, which is to say that Taylor is pursuing a senseless policy for the comforting sake of outdated norms.

Future forecasts

The ACIL Allen Opportunities for Hydrogen Exports model projected a mid-case forecast of 500,000 tons of hydrogen per annum by 2030. To put that in perspective, if we continue only with what we have already and what we have under construction, by 2025 we will have less than 3,000 tons per annum by 2025.

This is to say, if we don’t scale up renewable hydrogen production capacity by 160 times by 2025, we’ll be just 497,000 tons short of the ACIL Allen mid-case.

For an increase of that scale, Australia needs to put multiple industry-scale (100 MW-plus) renewable hydrogen projects in place over the next few years or the cost of production will remain too high and the hydrogen opportunity will be tentative, if not lost.

The renewable hydrogen opportunity cannot afford to be lost, as the scope of its Promethean potential is unfathomable, but there is much that can be understood already. If renewable hydrogen breaks the $2 per kilogram barrier, for example, it could immediately replace the domestic market for natural gas feedstock and provide a low-cast pathway to a green ammonia export industry, let alone Australia’s grander export ambitions. But, of course, “industry-scale renewable hydrogen development will require government and industry support to enable the adoption and the continued reduction in the cost per kilogram of renewable hydrogen … At levels below A$1.95 between 2025 and 2030, Australia will be able to transition a domestic market and be competitive in the forecast export markets.”

Currently, it is estimated that only 2% to 4% of the world’s hydrogen is produced via electrolysis.

Iberdrola will develop a large green hydrogen project from renewable energy sources in Puertollano, according to what the city council has made public, which, in turn, mentions an article published in the economic newspaper Expansión.

The project will involve an investment of up to 150 million euros in a plant that will be one of the largest in Europe of its kind, that is, production of hydrogen from photovoltaic energy, unlike other systems, which are based on fossil fuels pollutants. The group's goal is to achieve decarbonisation and cheaper hydrogen in the future, which is now basically used in industry, but is beginning to have other applications, such as electric vehicles.

According to Iberdrola estimates, published last week by Expansión, the Puertollano plant will consist of a 100 MW experimental photovoltaic plant that will incorporate bifacial panels and string inverters, as well as a 20 MWh lithium-ion battery storage system. and 5 MW. It will also have a green hydrogen production system through electrolysis: divided into stackable modules that allow the plant to be expanded, according to the identified hydrogen demand needs. In this regard, different technologies will be tested: alkaline, proton exchange membrane, and solid oxide.

It will also have a main hydrogen storage system in pressurized tanks and an experimental storage plant for other technologies such as LOHC (organic liquid carrier hydrogen), as well as a control system that allows the optimal balance between renewable production, use of the battery and the energy dedicated to the production of green hydrogen.

Ideal location

"The choice of Puertollano as an enclave to launch the project is not accidental", they explain from the town hall. “It is a strategic place from which Iberdrola will not only be able to produce hydrogen, but will also be able to commercialize it for industrial use to adjacent companies for their production processes. The project will be located on the land that Iberdrola has had in Puertollano for years, and where it had already begun to build the photovoltaic. In Puertollano there is also the National Hydrogen Center. To distinguish itself from other hydrogens, Iberdrola will promote the creation of a green label for those produced with electricity before the authorities ”, they add.

Together with the project, Iberdrola will promote the creation of a 'green' label for the hydrogen produced that ensures that its carbon footprint is zero, thus helping hydrogen users to reduce their CO2 emissions.

The power company claims that decarbonising global hydrogen through its production with renewable electric energy would mean an increase in electricity demand of more than 10%, which would allow for the flood of renewable energy projects that the Government plans to incorporate with the new energy plan. .

Other pioneering projects

This project joins those that have been announced in recent weeks: the green hydrogen production plant in Lloseta, a pioneer in Spain, will start operating from 2021 thanks to the Power to Green Hydrogen Mallorca project, and will allow a generation of up to 10 MW of production.

The Fundación Hidrogen Aragón coordinates a project to promote decarbonisation in Europe: The HIGGS project, which is now being launched in Huesca, will study for 36 months the possibilities of injecting hydrogen into current natural gas networks as a way to reduce emissions of CO2 in sectors difficult to electrify.

Enagás and Ampere will be the first to produce hydrogen with solar energy in Spain: both companies have signed an agreement for the joint development of several R&D projects for hydrogen production with solar and batteries.

Tecnalia, Engie and the University of Eindhoven (TUe) create in Bizkaia H2SITE, a startup to produce green hydrogen on site.

The Australian Renewable Energy Agency (ARENA) has announced a $1.25 million (US$807,495) grant to Queensland government-owned electricity generator Stanwell Corp. to assist a feasibility study for a renewable hydrogen demonstration plant, which will be located next to the company’s existing power station near Rockhampton. Stanwell’s $5 million study, which started in July 2019, is investigating the technical and economic feasibility of hydrogen electrolysis projects above 10 MW in size. If built, it will be the largest green hydrogen electrolysis plant in Australia.

To offset 100% of the emissions associated with running the electrolyzer, Stanwell will procure energy and green certificates from renewable energy projects in the region. This will be yet another innovative deal for the publicly owned generator, following last year’s network support agreement between Stanwell’s Kareeya Hydro Power Station and Pacific Hydro’s 100 MW Haughton Solar Farm. Under that deal, the services provided by Kareeya will strengthen the regional grid, which is subject to lower system-strength levels, to operate the solar project in line with generator performance standards.

A key outcome of the study will be to define the most valuable end use for renewable hydrogen. The utility-scale electrolyzer will enjoy the advantages of the existing power station to use pre-existing land approvals, network connections, and access to demineralized water, which is required for hydrogen production.

The project could demonstrate the role that renewable hydrogen production can play in an electricity system. In particular, the hydrogen electrolyzer could be used as a complementary energy market load that can ramp up in times of excess energy supply, such as peak solar output during the day. It could also aid system security through participation in Frequency Control Ancillary Services (FCAS) markets or future markets such as Fast Frequency Response (FFR).

“Through Stanwell’s feasibility study we’re showing a new option for producing and using renewable hydrogen. This will create opportunities across the domestic economy and help to position Australia to become a major renewable energy exporter,” ARENA CEO Darren Miller said. The ongoing study is expected to be completed later this year.

The hydrogen industry in its infancy in Australia, but the study will determine the optimal conditions for electrolyzers operating at high capacities. “The construction and operation of a utility-scale electrolyzer is important to demonstrate the costs associated with producing renewable hydrogen at scale,” Miller said. “If feasible, this could help underpin future commercial scale deployments leveraging existing network infrastructure at other power stations, and play a role in driving down the cost of domestic hydrogen production.”

ARENA has committed approximately $50 million towards hydrogen initiatives so far, including more than $22 million to R&D projects, and almost $28 million to demonstration, feasibility and pilot projects. In some of its earlier Queensland initiatives, ARENA announced it was providing $2.9 million in funding to two studies looking at the potential to use solar and wind-powered hydrogen produced via electrolysis to increase ammonia production at facilities which currently rely on gas as feedstock.

Ten years ago, the Tecnalia research and development center and the EIndhoven University of Technology (TUe) began collaborating on European projects around metal deposition technologies, and in 2018 they won the second EARTO Innovation award. A year later, they created a limited company, H2SITE, which French power company Engie has just joined through its corporate venture capital fund, Engie New Ventures.

The new company will be located in Bizkaia and will develop a technology for small and medium-scale distributed hydrogen generation, of high purity and low cost, using advanced membrane reactors. “For the creation of this new company, the strategy developed by Tecnalia in the field of gas separation membranes has been key. This technological excellence is combined with the strategic collaboration established together with the University of Eindhoven, for the development of advanced membrane reactors ”, the company states in a statement.

The project will represent the first investment by Engie New Ventures, one of the largest global funds in the utilities sector, in start-ups in Spain.

The new company has received from the beginning the support of the Provincial Council of Bizkaia, and will have an initial staff of 3 people for the first year of activity. H2SITE will provide low cost, high purity small and medium scale distributed hydrogen for both stationary applications and isolated areas requiring energy and mobility. "H2SITE will facilitate the deployment of 100% green electric mobility, opening up the possibility for on-board systems, within the vehicles themselves, to generate hydrogen," says the company, adding that "as a hydrogen technology platform, H2SITE will be capable of producing hydrogen from various compounds, such as biomethane, ammonia, bioethanol, etc. "

H2SITE will exploit a technology developed by Tecnalia and TUe, based on the intensification of processes, through advanced membrane reactors, maximizing the efficiency of the hydrogen production process and minimizing the necessary resources.

As for its industrial customers, H2SITE will offer a reduction of up to 40% of its current costs associated with the consumption of hydrogen, while reducing environmental impacts and avoiding regulatory and safety problems associated with the storage of hydrogen as it is an spot on demand.

“The main business objective of the startup is to become a state and European benchmark in the generation of green hydrogen and therefore, a relevant lever in the necessary energy transition. To do this, the challenge is to become the main supplier of hydrogen generated in situ for industrial use in stationary applications in prioritized industrial sectors, which are chemical, food, metallurgical, glass and electronics, which together represent a great part of the regional and national GDP ”, the statement ends.

Enagás and Ampere Energy recently announced the signing of an agreement for the joint development of several R&D projects for hydrogen production with solar and batteries.
