Researchers use sea water to produce green hydrogen at almost 100% efficiency.

The Adelaide University team found a way to cleanly make H2 without requiring fresh water.

Among the challenges to large scale production of green hydrogen has to do with the use of fresh water in electrolyzers. The reason is that many parts of the world are already facing fresh water supply challenges due to worsening droughts caused by climate change.

Sea water hasn’t been a viable option because the salt in the water is highly corrosive.

The corrosion causes expensive materials such as catalysts made from precious metals to degrade. This not only drives up the expense but also the environmental impact of the process. That said, the researchers claim that they have been able to produce green hydrogen using sea water and have achieved an efficiency rate of almost 100 percent.

The researchers made a breakthrough in the use of sea water for producing renewable H2 when they added a layer of Lewis acid, which is a specific acid type, such as chromium(III) oxide, Cr2O3) on a catalyst made of a transition metal oxide. Not only did this make it possible to use less expensive and more available materials, but the process also proved to be highly effective, according to the researchers.

“The performance of a commercial electrolyser with our catalysts running in seawater is close to the performance of platinum/iridium catalysts running in a feedstock of highly purified deionised water,” said Associate professor Yao Zheng of the University of Adelaide.

“We used seawater as a feedstock without the need for any pre-treatment processes like reverse osmosis desolation, purification, or alkalisation,” added Zheng in an explanation of how the sea water was not required treated so that it was usable to make green hydrogen, as would be the case using existing methods.

“Current electrolysers are operated with highly purified water electrolyte. Increased demand for hydrogen to partially or totally replace energy generated by fossil fuels will significantly increase scarcity of increasingly limited freshwater resources,” said Zheng.

The research was published in the Nature Energy journal.

US regulator completes first SMR design certification rulemaking

The US Nuclear Regulatory Commission (NRC) has issued the final rule certifying NuScale Power’s small modular reactor (SMR), making it the seventh reactor design – and the first SMR – to be cleared by the regulator for use in the USA.

The final rulemaking is the last stage in the design certification process, which allows a utility to reference the design when applying for a combined licence to build and operate a nuclear power plant anywhere in the USA. Site-specific licensing procedures must still be completed and a combined construction and operating licence obtained before construction can begin.

The NRC accepted NuScale’s design certification application for a plant comprising up to twelve 50 MWe power modules in March 2018. The regulator issued its final technical review in August 2020, and the NRC Commission voted to certify the design in July 2022. The company has subsequently uprated the capacity of the power unit to 77MWe and earlier this month submitted an application for NRC approval of a 6-unit configuration based on the uprated design. NuScale’s SMR plant has been known as VOYGR since December 2021.

NuScale Power President and CEO John Hopkins described the rulemaking as “historic” and acknowledged the role of the US Department Energy (DOE), which has provided more than USD600 million since 2014 to support the design, licensing, and siting of VOYGR and other domestic SMR concepts.

Porsche hydrogen engine prototype outperforms 8-cylinder gasoline engine

The luxury automaker has announced that its design matches performance with lower fuel consumption.

Porsche has developed a hydrogen engine prototype for luxury sports cars that will not only match a V8, 4.4-liter internal combustion engine while also reducing fuel consumption and maintaining emissions equivalent to ambient air.

Porsche created a digital version of the hydrogen engine using sophisticated virtual engine simulations. The jumping off point for the H2 drivetrain was the digital data set for its gasoline-powered counterpart. This was used as a benchmark that must be matched as a minimum by the H2 version.

Modifications to the conventional internal combustion engine included a higher compression ratio and combustion alternations to make it appropriate for H2 gas. It also includes a newly designed turbocharging system.

To be able to achieve clean H2 combustion, the turbochargers are required to offer about twice the air mass as is needed in a comparable gasoline-powered model. That said, the design was also required to compensate for lower gas temperatures with the alternative fuel, as this could cause a lack of propulsion energy.

Traditional turbochargers don’t have the capacity to resolve that issue, therefore Porsche Engineering was required to develop alternatives. In fact, they came up with four new turbocharging concepts.

Each of the alternative systems consisted of a number of electrically supported turbochargers. Additional control valves were added some within their electrically powered compressors and their air systems. Each of the alternative configurations had its own advantages and disadvantages according to the automaker. The best option has a heavy dependence on the hydrogen engine’s use. Back-to-back compressors were an important part of the design that rivalled the gasoline-powered model.

“The special feature of this design is the coaxial arrangement of two compressor stages, which are driven by the turbine or the supporting electric motor using a common shaft,” said a statement issued by Porsche. “The process air flows through the first compressor, is cooled in the intercooler, and then recompressed in the second stage.”

This allowed the hydrogen engine to achieve a 440kW maximum output as well as a top speed of 261km/h, aligning well with gasoline powered V8 engines.

The New Hydrogen Car that Travels 2,000 Kilometers with a Single Tank

Volkswagen is working on a new fuel cell that is much cheaper than the current ones and promises hydrogen cars that can travel 2,000 kilometers on a single tank. Volkswagen has just applied for the registration of a patent for a new hydrogen fuel cell that, in addition to being cheaper than the current ones , will be able, according to its creators, to give cars a range of up to 2,000 kilometers without refueling

This news represents a turn in the position that Volkswagen usually shows regarding hydrogen. Like Elon Musk does every time he has the opportunity, the German manufacturer’s CEO, Herbert Diess, denied the potential of hydrogen as a power source for electric cars in a tweet published in May 2022.

Herbert Diess, CEO, said: It has been shown that the Hydrogen car is not the solution to climate problem. “In transport, electrification has taken over. Fake debates are a waste of time. Please listen to the science.” The patent application for this new fuel cell, carried out together with the German company Kraftwerk Tubes, shows that Volkswagen does not want to lose the hydrogen train and works outside the public eye in the development of this technology.

Sascha Kühn, Kraftwerk CEO explains in an interview with Business Insider Germany: The main difference with Hyundai and Toyota hydrogen cells is that we use a ceramic membrane instead of the usual plastic one. That’s a big difference. “The big advantage of our solution is that it can be produced much cheaper than polymer fuel cells and it does not require any type of platinum”, a precious metal that makes the final cost of the product more expensive.

This technology, Kühn says, resembles solid-state batteries. According to the executive, both have almost the same electrolytes and a similar material structure. The difference is that, while solid-state batteries use a compact material to store energy, in fuel cells that role is assumed by hydrogen in gas form.

Lower energy cost, more autonomy; In addition, the new ceramic membrane, says Kühn, does not need to be moistened, so it does not freeze in winter, dry out in summer, or attract mold. The manager also points to another advantage that will save costs in the manufacture of vehicles: the fuel cell generates heat that can be used both to replace the car’s heating and air conditioning, which would also mean greater energy savings.

Although this patent has been requested together with Volkswagen, Kraftwerk assures that it does not work exclusively for a brand:

“Regardless of the manufacturer, our goal is for our technology to be launched in a series vehicle by 2026. We are talking about series of about 10,000 vehicles, spread over several car manufacturers,” says the CEO of Kraftwerk.

” Lithium is definitely not a way forward. Solid-state battery would be an option, but it’s not there yet,” explains Kühn, who sees his technology as an alternative for drivers who don’t have a suitable charging option on the go. home or do not want to waste their time at charging stations. According to the executive, with his system “we can travel up to 2,000 kilometers with a single tank of fuel.”

European Hydrogen Week

Saw the conclusion of the European Hydrogen Week, organised by Hydrogen Europe, in cooperation with the European Commission and the Clean Hydrogen Partnership, on 24-28.10.2022 and held in the Brussels Expo centre.

Over 3200 stakeholders of the hydrogen community were brought together to witness more than 120 exhibitors and 150 speakers covering all elements of the sector’s value chain. Across the exhibition room, attendees could get a first-hand view of the latest in electrolyser and fuel cell technologies as well as touch with hand and test hydrogen trucks, buses and cars.

As a member of the Hungarian Hydrogen Technology Association, HYDROGEN EUROPE, he was invited and participated in the event, where István Lepsényi, the president of the association, held a meeting with the leaders of the European and World associations.

On the second day of the event, the GHIAA, which was established in Seoul in 2022 with the participation of the hydrogen industry associations of 18 countries, officially admitted Hungary to its membership. According to their formulation, the international cooperation of key economic actors and the private sector is essential for the transition to the hydrogen economy, to combat global climate change and to achieve carbon dioxide neutrality.

The high-level policy conferences featured panels consisting of some of the most prominent stakeholders in the hydrogen industry and covered the most pressing topics facing this new industry: the need for both urgency and pragmatism in creating the regulatory framework, the unique challenges different sectors face to decarbonise and how hydrogen can help, and how to remain a leader in an industry that has caught the attention of the rest of the world.

Day two of the event was highlighted by a visit and speech from Mr. Frans Timmermans, Vice President of the European Commission, wherein he announced the release of €3 billion in new funds as part of the upcoming Innovation Fund call in November. These are on top of the €3 billion for the Hydrogen Bank already announced by President von der Leyen. EVP Timmermans said that green hydrogen is now “at the top of our agenda for the European Green Deal, but also for the recovery from the pandemic” and, that following the war in Ukraine, it would “play a key role in the energy transition and creating European energy sovereignty”.

About the success of the event, Jorgo Chatzimarkakis, CEO of Hydrogen Europe, said: “We accomplished something that is a landmark for our sector and a new reference point when it comes to energy related developments in Europe and globally. Thank you to all our exhibitors, speaker and attendees and we look forward to seeing again at next year’s edition on 20-24 November 2023.”

Another big day for European hydrogen

Members of the European Parliament have decided to support a hydrogen-based green transition in the transport sector, because they can see the bigger, long-term picture: that hydrogen is a necessary and opportune tool to achieve carbon neutrality and energy security in Europe. With this vote, the EP has sent a strong signal that clean hydrogen mobility is a viable and realistic solution to move away from fossil fuels in the transport sector.

In 19 oktober 2022 plenary vote, parliamentarians opted to keep the targets proposed by the Rapporteur Ismael Ertug and their committee colleagues in a vote earlier in October. A maximum distance of 100km between each hydrogen refuelling station, along both the core and comprehensive TEN-T networks, will mean that by the time the infrastructure is in place by end of 2027, up to 1,780 HRS could be available across Europe, suppling up to 1million ton of hydrogen per year, sufficient to power up to 59,000 trucks (assuming 60kg/truck per day). Under the council position in its General Approach, no more than 8,000 trucks could be supplied, and the lack of HRS coverage would make it unattractive for drivers and fleet operators.

With this vote, the EP has sent a strong signal that clean hydrogen mobility is a viable and realistic solution to move away from fossil fuels in the transport sector. We believe that a strong rollout of hydrogen refuelling infrastructure in Europe will act as a catalyst for similar policies around the globe. The AFIR vote also solves the “chicken and egg” problem – so often faced by new technologies. The roll-out of these stations will encourage vehicle manufacturers to bring more and better fuel-cell vehicles to the market, improving their performance and reducing their cost, which in turn will lead to uptake in fuel cell vehicle adoptions by both commercial and private users.


Thirty international and domestic large companies, enterprises and research workshops working in Hungary in hydrogen technology and related developments have also exhibited at the V4 PLUS international conference, hydrogen technology presentation and career guidance professional day entitled “Hydrogen – present and future in mobility”.
The two-day event at the ZalaZone Automotive Center focused on ongoing developments in hydrogen technology, V4 strategies, major national projects, H2 mobility processes, and the training of technology professionals.
On the day of the event conference (June 9), the leaders of the Hydrogen Associations of the Visegrád countries presented the novelties of the sector, after which the participants could listen to presentations on the European hydrogen-based mobility, hydrogen technology sector and its growth.
István Lepsényi emphasized in the greeting of the President of the Hungarian Hydrogen Technology Association; “Our world has changed drastically in recent years, but especially this year, because of the war. transition to energy. One of the most spectacularly evolving areas of this competition is hydrogen technology and related mobility.

In her opening remarks, Daniella Deli, Undersecretary of State for Energy and Climate Policy at the Ministry of Technology and Industry, emphasized the importance of developing new legal environments, certification schemes and guarantees of origin related to hydrogen technologies, education and domestic developments. He said “the government is currently working on both the necessary changes within the legislative process and the incentive schemes.” The first package of legislative proposals is expected in the second half of this year, and the first calls for proposals will be published in the autumn


The representative of the Minister of Industry and Trade of the Czech Republic, Jozef Síkela, emphasized the importance of international co-operation and the importance of common thinking. Said; “We can really learn a lot from the automotive industry in the development of hydrogen technology because of the amazing development and international cooperation in the sector.” He emphasized that the ZalaZone track, which will host the conference, is a good illustration not only of the growth of the Hungarian automotive industry, but also of the developments and innovations in the sector.


Jan Weiterschütz, a special adviser to the Slovak Ministry of Economy and Minister Richard Sulík, explained that Slovakia, like Hungary, has limited opportunities for hydrogen production, but sees a very good chance of creating a hydrogen network connecting the V4 countries. He said “there are still many steps to be taken to reach the 2030 climate targets, but that can be done in partnership. He added that the current conference is also an important starting point for this work.


Tomoho Umeda, President of Hydrogen Poland and the Chamber of Commerce, highlighted that we are facing the biggest historical crisis, the global energy crisis, in which no one can predict the future of their own business or economy. In this situation, it is very important to be able to pinpoint the role of hydrogen.
He said that hydrogen is not the end product, the solution, but something that helps us store and transmit energy from renewable sources to end users.
He added that hydrogen-related developments and technologies are already available and we need to apply them, as we are already at a disadvantage.
Jae-do Moon, President of the World Hydrogen Association, and Maja Bakran Mrcich, Director-General for Mobility and Transport of the European Commission, welcomed the conference in a video message.


Recent events, rising energy prices, are accelerating the transition to green and renewable energy. The basis of the sovereignty of every country is to produce as much energy as possible domestically and to obtain imports from as many sources as possible. And this will mobilize a lot of resources in the coming years, so there will be countless ideas, innovations and developments competing for the money. One of the most spectacular areas of this competition is mobility, as technical progress in this area, various vehicle technologies and their availability on the market appear very quickly from week to week.

There are no ready-made business models in the field of hydrogen mobility yet, so learning about common thinking, each other’s plans and existing good practices is extremely important for Hungary. As the study of the Green Truck Project prepared by the Association points out, hydrogen-based mobility cannot be solved as a country’s own “internal affair”: expensive charging infrastructure and the utilization of expensive vehicles should be maximized as early as possible, and this should only be it is possible to create well-functioning hydrogen corridors and then networks, at least in the neighboring EU Member States, but even more so throughout the EU. For this reason, it is advisable to get to know at least the development plans of the hydrogen filling infrastructure in the neighboring countries and to coordinate them as far as possible. This is required not only by the relevant EU regulations (eg the Alternative Fuel Infrastructure Directive) but also by common sense.

The Hungarian Hydrogen Technology Association with the Ministry of Technology and Industry will organize the V4 PLUS international conference and hydrogen demonstration “Hydrogen – present and future in mobility” on the ZalaZone test track and event center on June 8 and 9, 2022. professional day.

The aim of the event is for the participants to get acquainted with the current developments in the Hydrogen sector, the most significant V4 national projects and strategies in progress. The conference will focus on the processes taking place in the field of H2 mobility, the fastest growing areas of the hydrogen technology sectors. The exhibiting large companies and research workshops present their pioneering ideas and innovations that provide a competitive advantage.

It is extremely important that the training of professionals dedicated to technology is continuously strengthened, therefore on the first day of the event (June 8) the Hungarian Hydrogen Technology Association organizes professional lectures for universities and students participating in their training, Zala Zone test track and related exhibition crawl.

On the day of the conference (June 9), following the opening speech of the Minister of Technology and Industry, the Hydrogen Associations of the Visegrad countries will present the sector, followed by presentations on the European hydrogen-based mobility, hydrogen technology sector and possible growth. other cross-border cooperation programs.

Invitees can be active participants in the panel discussions, view our outdoor and indoor industrial exhibition and try out a wide variety of hydrogen-powered vehicles at the Zalazone test track.

The hydrogen train was introduced by Siemens Mobility and DB

The Mireo Plus H locomotive and its associated infrastructure have been set up to replace multi-unit diesel locomotives in both suburban and regional transport. The aim is to reduce CO2-related CO2 emissions.

The locomotive was developed and created for the H2goesRail project in Germany. The entire project also included the development of a new H2 storage tank trailer from DB to accommodate mobile refueling. The units presented by the companies were designed for the H2goesRail hydrogen train project.

The German Federal Ministry of Digital and Transport (BMDV) supported the H2goesRail project with € 13.74 million under the National Hydrogen and Fuel Cell Technology Innovation Program (NOW GmbH). This program coordinates funding guidelines while Jülich monitors implementation.
