The MAN subsidiary Quest One, formerly H-Tec Systems, celebrated the opening of its “Gigahub” in the north of Hamburg at the end of September 2024. It wants to produce flexible PEM electrolyzers with meter-high stacks on a large scale.
It was one of those success moments of the energy transition where everyone gladly stood on stage and whose importance can be easily recognized by the number of celebrities. First and foremost, of course, was German chancellor Olaf Scholz. It was a long time since Scholz was in Hamburg-Rahlstedt, he said. As a young kid, he had gone to school there. “But back then, we didn’t yet learn that hydrogen could be used to power airplanes. This was at most a topic for researchers,” recounted Scholz in the brand new factory hall of Quest One.
From Hamburg politics, the first Bürgermeister Peter Tschentscher as well as the economy senator Melanie Leonhard made an appearance – usually no more than one of them comes to such celebrations. From Berlin came the parliamentary secretary Michael Kellner from the federal economy and climate protection ministry and Till Mansmann, green hydrogen officer of the federal ministry for education and research. From Quest One’s parent company MAN Energy Solutions and its parent company Volkswagen, the heads of the supervisory board arrived respectively, Gunnar Kilian und Hans Dieter Pötsch.
The reason for all the fuss: The company Quest One, who the day before was called H-Tec Systems, wants to start electrolyzer production on a gigawatt scale in the northeast of Hamburg.
PEM electrolysis getting big
The company story of Quest One is a story of the scaling of PEM electrolyzers. PEM electrolysis runs at moderate pressure and medium temperatures, so it offers a good compromise between efficiency and flexibility. This makes it the technology of choice when it comes to producing hydrogen using the unsteady energy sources of wind and sun. But compared to alkaline electrolysis, it has decades of industrial scaling to catch up on.
H-Tec Wasserstoff-Energie-Systeme, as Quest One was called until the end of September, began producing mini PEM electrolyzers in 1997. They were primarily intended to introduce schoolchildren to the physical principle of electrolysis. With alkaline electrolyzers powered by hydropower, at this point in time ten thousand cubic meters of hydrogen hourly was being generated in Norway and Egypt for fertilizer production. That hydrogen could seriously become a storage technology for solar and wind power was believed at the time by at most a handful of visionaries.
Since then, not only renewable energies have become significantly cheaper. PEM technology has also caught up significantly. In 2010, the northern German energy transition company GP Joule bought H-Tec. The electrolyzers grew to a few hundred kilowatts, at least suitable for small applications. In 2019, MAN Energy Solutions got aboard and H-Tec brought the first megawatt electrolyzer onto the market: nine stacks of 110 kW each, each the size of a beer crate, together with the associated peripheral systems, mounted ready for connection in a 40-foot container – a practical solution for small wind farms and individual hydrogen refueling stations.

Gigawatt plans for green hydrogen
To supply steel mills, fertilizer manufacturers and refineries with hydrogen, this is still far from enough, nor is it enough for the target of 10 GW of electrolysis output that the former Ampel Coalition leading the federal government set for 2030. That is the dimension in which Quest One also wants to get involved. The new name should make that clear. It should not only say that climate protection is the most important of all tasks, but also that the company wants to avoid one percent of global greenhouse gas emissions with green hydrogen from its electrolyzers, explained Robin von Plettenberg, CEO of Quest One at the opening ceremony.
The approximately 800 guests applauded loudly. In general, when the “Gigahub” was officially put into operation, there was no shortage of buzzwords and emotion. Across the screen flickered images of parched soils, raging floods, burning forests, followed by an hourglass – and the shiny, metallic, donut-shaped logo of Quest One. The project is “part of something really big,” said von Plettenberg.
From handcraft to series production
So far, the production hall has primarily provided space for large plans. On the opening day, the clean room with the actual production almost completely disappeared behind the huge video screen. But innovations are not always reflected in large machines. While today you can buy turnkey solar and battery factories with little out of pocket, Quest One with each production step that runs automated and reliably in Rahlstedt has conquered a piece of new technological territory.
The research and development center, which is also located at the gigahub, helps here. Until recently, for example, employees still assembled the electrolysis cells into stacks by hand, which took hours of work. This step requires absolute precision, because the tiny hydrogen molecules can escape through the smallest gap and thus make the entire stack unusable. As Quest One celebrated its opening at the end of September, it had already succeeded in delegating this task to robots. They get the job done in a quarter of the time. Less than an hour is what it now takes to produce a stack.
Now that the automated handling is running, Quest One is also daring to speak of a new generation of megawatt stacks. Three meters high and weighing three tonnes is what they will be, it was said. The hall should be largely full by the end of 2026; then production of the megawatt stacks should begin. Such stacks could also make it easier to implement projects beyond the 100‑MW mark with PEM electrolyzers. In the course of 2026, Quest One wants to move in the direction announced in the press release – a manufacturing capacity of 5 GW annually.
A few months after the opening, everyday life has returned to Quest One. For the offices, there is still some expansion work to be done. In the clean rooms, however, series production is taking place. In the huge hall, instead of bistro tables and chairs, there are now shelves to store the stacks. They will be sent to the company’s headquarters in Augsburg, where the production of the electrolyzers is located.
For these electrolyzers to be able to produce really clean hydrogen, a lot still has to happen outside the factory. Wind and solar parks must be built and financed, as well as networks and storage for the hydrogen.
Even at the opening, the panel discussion after the ceremonial push of a button showed that those present were very aware of the challenges. “The real work is just beginning now,” concluded Jürgen Klöpffer, chief financial officer of MAN Energy.

37th BImSchV enables extra revenue for renewable fuels
Germany’s greenhouse gas reduction quota (GHG quota) is a climate policy tool which is designed to cut the country’s transport emissions and encourage the use of renewable energy in the mobility sector. It implements the provisions of the European Union’s Renewable Energy Directive in German law and aims to meet the minimum renewables share required in the transport sector for 2030 and beyond.
The high GHG emissions from transportation are attributable to the use of fossil fuels. This is the reason why petroleum companies, or rather fossil fuel distributors, are obliged to compensate for a certain percentage of their emissions and to invest in lower-emission alternatives. This percentage is termed the GHG reduction quota and is set at a minimum of 9.25 percent for the year 2024. The level will then be raised continually, reaching 25 percent in 2030.
To meet these targets, the German Federal Immission Control Act (BImSchG) allows certain fulfillment options, such as biofuels, charging current or electrolytic hydrogen, to earn credit through quota trading, thus making it possible to generate attractive amounts of additional revenue. Companies which are subject to quotas pay distributors of renewable fuels for the emissions savings, enabling them to meet their targets and thereby avoiding a penalty of EUR 600 per metric ton of CO2. The 37th Ordinance on the Implementation of the Federal Immission Control Act (37th BImSchV), in particular, regulates renewable fuels of non-biological origin or RFNBOs while the 38th BImSchV, for example, governs charging current.
Renewable fuels of non-biological origin
In March 2024, the German parliament passed an amendment to the 37th BImSchV which covers RFNBOs. It makes a wide spectrum of different electrolytic fuels eligible under the GHG quota, including green hydrogen. Nevertheless, the new ordinance only affects fuels that are brought into circulation from July 1, 2024.
The provisions mostly apply to the production of RFNBOs and hence directly to producers. However, the companies that are eligible for the quota and entitled to earn revenue under the scheme are not the producers but the RFNBO distributors, which are generally the operators of RFNBO refueling stations. Furthermore, the use of RFNBOs in the refinery is also possible. In this case, the refinery itself is considered a distributor and is therefore eligible under the quota scheme.
Fundamentally, for green hydrogen and RFNBOs to count for the GHG quota, the power purchasing criteria need to be met as set out in the Delegated Regulation EU 2023/1184, in addition to a minimum GHG saving of 70 percent, calculated according to the provisions in the second Delegated Regulation EU 2023/1185. To provide evidence of this, production plants, including potential suppliers, have to be certified in a certification system recognized by the European Commission (e.g., REDcert EU or ISCC EU).
Only once certification has been obtained can the produced RFNBO be counted – provided the minimum saving of 70 percent is met. These rules apply as part of the German GHG quota for RFNBOs as used in the transport sector, but also set standards for RFNBOs as used in other EU states and in other end-use sectors (but without the possibility of earning quota revenue).
Once RFNBO certification systems have been recognized by the European Commission, the relevant market participants can seek certification. Prior to this, it is not possible to produce RFNBO and use it for the GHG quota. Pre-certifications are, however, possible and can speed up the certification process in certain circumstances but they are not legally valid in relation to the 37th BImSchV and also do not provide for retrospective recognition of renewable fuels that have been produced.
Partially renewable fuel
The power purchasing criteria from EU 2023/1184 are replicated exactly in national law and can therefore likewise be found in the 37th BImSchV. A distinction needs to be made between fully and partially renewable fuel. Fully renewable fuel must generally meet all power purchasing criteria (see fig. 2), including the conclusion of a green power purchase agreement (green PPA), in other words a contract for the supply and purchasing of renewable electricity, for example between the operator of a wind farm and the operator of an electrolyzer. Partially renewable fuel is not required to meet these criteria. Thus the first stage is to check whether the fuel meets the full RFNBO classification under the ordinance.
An electrolyzer could, for example, purchase mains electricity and have to redeem only the electricity guarantees of origin in line with the average renewables share without fulfilling the other power purchasing criteria (whereby no biomass-based guarantee of origin is permitted to be used). In such cases, the average renewables share of the electricity consumed in Germany, known as RES-E, would be referenced two years before the year of production. If the renewables share were, for instance, 50 percent, a maximum of 50 percent of the fuel produced in this way would be recognized as RFNBO.
In practice, however, production via this kind of power purchasing alone is not possible in Germany since the relatively high emissions factor for mains electricity is taken into consideration and this usually means the minimum saving of 70 percent is not met. The assignment of total emissions to products such as heat and oxygen that have been recovered from the production plant could provide a remedy, like proportional production together with production from fully renewable fuel via the use of a green PPA.
Emissions can be assigned in the case of the electrochemical production of hydrogen, heat and oxygen, for example, using the economic value of the products. However, if all products have an energy value, emissions must be assigned according to the energy content. This improves hydrogen’s GHG footprint.

Fig. 2: Overview of current regulations
Fully renewable fuel
Alongside partially renewable fuel, the production of fully renewable fuel is also possible. For a fuel to qualify as fully renewable, the criteria need to be met as set out in fig. 2 according to the particular power purchasing scenario, whereby 100 percent of the fuel produced can be counted as RFNBO. If a proportion of the production uses electricity that does not meet these requirements, the result would be proportionally less than 100 percent (depending on the renewables share in the power grid at the particular production site).
Example
An electrolyzer purchases 70 percent of its electricity via a green PPA (Scenario 2 from fig. 2) and 30 percent on the spot market, including the redemption of electricity guarantees of origin. If the renewables share in the grid is 50 percent, then this would mean a maximum of 70 percent plus 15 percent, in other words 85 percent RFNBO; the remaining 15 percent could be marketed as low-carbon hydrogen but cannot be used for the GHG quota. Whether 85 percent is actually classed as RFNBO, will only be decided if it is clear whether the minimum saving of 70 percent is met for the overall amount.
The method for calculating this minimum saving and the GHG intensities of various RFNBOs is presented in the second delegated regulation and its annex (EU 2023/1185). It therefore also determines the starting value for emissions savings that can be marketed within the framework of the German GHG reduction quota. Here, the 37th BImSchV refers directly to the delegated regulation.
More clarity on revenue potential
As a basic principle, all emissions throughout a specific fuel’s life cycle need to be recorded (well-to-wheel analysis). This includes the emissions from feedstock (raw materials, auxiliary materials and consumables) as well as, for instance, electricity, treated water, nitrogen or electrolyte, such as potassium hydroxide, the emissions resulting from production (e.g., leaks or waste treatment) and emissions caused by transportation via diesel tractor units and distribution at the refueling station. In comparison with fuels for combustion vehicles, no additional GHG emissions occur during use. In the case of hydrogen, however, emissions quickly build to a critical level during transportation and distribution since the diesel trucks used for carrying hydrogen cannot currently be replaced with sustainable forms of propulsion for legal reasons and the refueling stations generally are not permitted to use a green PPA, meaning the power consumed for compression and cooling has to be set off against a correspondingly poor emissions factor. As it stands, there are not yet standardized emission values, e.g., for compression and cooling at refueling stations or for production via electrolyzers with low capacities (roughly < 5 MWel).
Requirements for feedstock emissions
In the case of hydrogen or RFNBOs classified as fully renewable, the electricity used for production is given an emission factor of 0 kg CO2/GJ. However, there are also requirements for hydrogen that is only partially renewable. Here, use is made of the average GHG intensity of mains power for the particular EU member state in which the hydrogen production plant is situated. Yet since all RFNBOs have to demonstrate a GHG saving of at least 70 percent compared with the fossil-fuel reference, it is currently possible to qualify with relatively poor mains electricity values only under certain conditions, for instance the assignment of emissions to any commercially used byproducts such as heat and oxygen or proportional production in compliance with power purchasing criteria (via a green PPA). In addition to electricity, all other feedstocks need to be incorporated into the emissions calculation. The expertise of specialist consultants can be called upon for drawing up certifiable calculation methods and carrying out an assessment of the sustainability criteria.
The GHG intensity for the RFNBO (feedstock, production, transportation and distribution) is permitted to be a maximum of 28.2 kg CO2/GJ, after taking into account the minimum saving, in order to qualify for the GHG quota. Quota trading requires that the “last interface” issues proof of sustainability for the relevant RFNBO quantities produced and transferred to suppliers. Only the last interface is entitled to issue this proof. Normally this is the producer which manufactures the fuel to the quality required for use in transport.
This proof of sustainability contains, among other things, the confirmation that all power purchasing criteria and GHG requirements have been met. It also details the GHG intensity of the RFNBO which has been calculated for the particular designated use. For this, the last interface again uses the GHG intensities of possible upstream interfaces and adds to these its own emissions, including downstream transportation and distribution.
Proof of sustainability can only be issued if there is a valid certificate for the production site which has been supplied by one of the certification systems recognized by the European Commission. Proof of sustainability and certificates must also be set up for verification purposes in the Union Database for RFNBOs and in the register of the relevant authority of the German Environment Agency. Both registers are currently under construction.

Fig. 3: From GHG intensity to GHG reduction quantity
This production-specific GHG intensity of the RFNBO can then be used as a basis for calculating the GHG reduction quantity for the GHG quota. Fig. 3 above assumes a GHG value of 20 kg CO2/GJ H2, which would work out at a reduction quantity of almost 28 kg CO2 per kg H2 (incl. triple accounting).
This reduction quantity falls over time, however. If the GHG reduction quota increases over time – as foreseen by legislators – the reduction figure would decrease as a result of green hydrogen since even this type of hydrogen has to meet the reduction quota. Additional revenue from green hydrogen can be deduced depending on the achievable market prices per metric ton of CO2: For example, if the market price is EUR 130 per ton of CO2 (no cap quota), this can generate additional revenue of around EUR 3.60 per kg H2 in 2024.
For quota revenue to be paid, in general the quota transfer needs to have taken place previously through the relevant biofuel quota center at the main customs office. Here, specialist quota service providers can take care of quota trading, supply quota trading agreements and provide support to ensure formal requirements and application deadlines are met. In addition, trading models with an index price or fixed price for RFNBOs can be set if requested (including over several years), thus ensuring secure and predictable quota revenue.

Interview with Dr. Jochen Köckler, chairman of Deutsche Messe
“We’re bringing people together.” With these words Dr. Jochen Köckler, board chairman of Deutsche Messe, described Hannover Messe’s ambition to once again be the place to go in real life for exhibitors and visitors in the industrial sector in 2024. This year, the focus will be even more on hydrogen than in 2023. Köckler emphasized the need for more togetherness by saying that the establishment of an H2 economy will “only succeed if people from politics and commerce work together.”
H2-international: Dr. Köckler, in 2023, hydrogen was already one of the five core topics you showcased during Hannover Messe. Will the presence of H2 technology increase again in 2024?
Köckler: We assume that we will experience a significant increase in the area of hydrogen. At Hydrogen + Fuel Cells Europe as well as in the other exhibition areas of Hannover Messe, the signs are pointing to growth.
H2-international: What will you, on the part of Deutsche Messe, do in order to underline the major importance of the topic hydrogen?
Köckler: With Norway as this year’s partner country, we are focusing on the topic of energy, and with that especially the topic of hydrogen. Germany and Norway agreed on an energy cooperation back in January 2023. In the joint declaration on hydrogen, the two countries reaffirmed their intention to establish a large-scale supply of hydrogen, including the necessary infrastructure, by 2030. Norway will therefore position itself with its joint stand in the energy section of the Hannover Messe.
H2-international: With Hydrogen + Fuel Cells Europe, one of the most important H2 trade fairs in Europe is part of your industry show. What can visitors expect there?
Köckler: Hydrogen + Fuel Cells Europe has been the meeting place for the international community for around 30 years. They meet there, they discuss all critical topics in two forums there. The Public Forum deals with current topics such as the question of what contribution hydrogen can make to reducing CO2. In the Technical Forum, new products and solutions are presented. Visitors who are interested in the topic of hydrogen will be given a comprehensive overview of technical innovations there but also of different fields of application.
But H2 solutions will be shown not only at the Hydrogen + Fuel Cells Europe in hall 13, but also in other areas of the Hannover Messe. We are pleased that increasingly more exhibitors with hydrogen-related and fuel cell-related products are represented. In total, we expect more than 500 companies in Hannover. This will give the hydrogen economy a real boost. Salzgitter AG, for example, is informing on climate-neutral production of green steel from green hydrogen in hall 13.
H2-international: Were you at the Hydrogen Technology Expo in Bremen? Are you impressed by how quickly this trade fair has grown and how professionally it has matured?
Köckler: When a topic gains in importance, new opportunities for trade fairs naturally arise. That is normal. Our advantage is that we have been working in the field of hydrogen and fuel cells for decades and, in all this time, have established a unique community. This appreciates the integration of Hydrogen + Fuel Cells Europe in Hannover Messe, as it has direct access to industry, the energy sector and politics here. No other trade fair in the world has this.
H2-international: What is your view of the German events sector? What are the advantages of Hannover Messe compared to now large European H2 trade fairs such as those in Rotterdam or Paris?
Köckler: Hannover Messe is a horizontal trade fair at which representatives from politics, commerce and academia exchange ideas every year. They cross-fertilize each other and work together to drive developments forward. In hall 2, for example, scientists from leading research institutes will be showing what products and solutions are being researched. In the other halls of the Hannover Messe, the focus is on specific applications. Politics will be even more strongly represented this year than in previous years, as in addition to the German chancellor Olaf Scholz, German economy minister Robert Habeck and Ursula von der Leyen, the president of the European Commission, are expected
The EU will be strongly represented overall. On the first day of the fair, the EU conference “EU as Home of the Decarbonised Industry” is taking place in the Convention Center on the fairgrounds in Hannover. At the event, industry representatives can exchange ideas with high-ranking EU politicians to discuss relevant topics such as the Green Deal. This possibility only Hannover Messe offers. Particularly in the energy sector is contact with politicians important, as all political decisions in this area have an impact on businesses.

At Fraunhofer FEP (Fraunhofer-Institut für Organische Elektronik, Elektronenstrahl- und Plasmatechnik), a pilot plant for the coating of metal sheets and strips is being used for the efficient coating of bipolar plates for electrolyzers and fuel cells. The institute, according to its own statements, is a leader in the development of electron beam and plasma technologies. This expertise could also advance hydrogen technology in the future.
One example of this would be plasma-activated electron beam evaporation. This is a vacuum coating process that enables both high throughput and high coating quality. Exactly this combination is crucial for the coating of bipolar plates for electrolyzers and fuel cells. Because these have to function for a long time, stably, in a chemically aggressive environment. For this, they must receive coatings that reliably protect the plates and at the same time guarantee electrical conductivity.
Using electron beam evaporation, coatings to form a certain shape can be applied to the metal strip before these are stamped into bipolar plates, stated Burkhard Zimmermann, division manager for electron beam technologies at Fraunhofer FEP. The coating of the material is a crucial step for scaling the production with a roll-to-roll process. The challenge here is the formability of the coating. To ensure this, a dense macrostructure of the coating with the largest possible crystallites is required. Exactly these layer properties can be realized by the developed processes.

HPS presents new product generation
The company HPS Home Power Solutions has unveiled a new generation of its seasonal energy storage system. The Picea 2 now uses lithium batteries, which makes installation in the home easier due to the lower weight. With twice the power, the appliance is also equipped for e-mobility and heat pumps.
The new research and development site is located almost directly next to the youth center of FC Union Berlin in an industrial area in Berlin-Niederschöneweide. In the future, not only kickers but also installers and partners will be trained there. But not only that; the new version of the seasonal storage unit is also to be manufactured there. “On-site installation is even more cost-effective for us, as the transport costs come out lower,” stated company founder and CEO Zeyad Abul-Ella – left in December 2023 and since then only still a shareholder – at the first presentation of the new device to an exclusive circle of visitors.
Nine years after its founding and a good five years after the first presentation of a Picea model at the trade fair Energy Storage in Düsseldorf 2018, there is a whole series of further developments of the product. The device has needed to change with the times. With Picea 2, the output power has therefore doubled to 15 kilowatts, which makes it possible to cover higher energy requirements, for example for an e-car or a heat pump. In the event of a power failure, the backup power supply ensures that important installations in the household are supplied with a stable power supply. “For each of the three phases of the three-phase current, the device now delivers five kilowatts of power,” explained Abul-Ella.
The new generation of the storage system also offers an increased connected load for photovoltaic systems – picking up on the trend in the market. Through new power electronics, according to HPS, efficiency was able to be increased, which means that higher levels of self-sufficiency are now possible. The energy utilization efficiency (Nutzungsgrad) including heat utilization is 90 percent. The electrical efficiency is between 35 and 40 percent.
Cooperation with competent partners
The device now uses an external inverter from SofarSolar, in which the software for the storage system has accordingly been adapted. “We do what we are really good at. For all other components, we rely on cooperation with partners,” said trained civil engineer Abul-Ella. The latter applies to both the inverter and the lithium batteries.
The AEM electrolyzer comes from the German-Italian company Enapter. The abbreviation AEM stands for anion exchange membrane. The technology uses more cost-effective materials such as steel instead of titanium and combines the advantages of alkaline electrolysis with the flexibility and compactness of PEM electrolysis. Enapter co-founder Vaitea Cowan was also present at the product launch, and Hans-Peter Villis, former EnBW (Energie Baden-Württemberg AG) director as well as partner from the very beginning and today chairman of the supervisory board at HPS.

Specifications for developers
“A tough requirement for the technical developers was to retain the dimensions for the slide-in boxes for the electrolyzer and the fuel cell in the energy center of the original Picea,” stressed Abul-Ella. The first Picea customers are pioneers. They should therefore also benefit from the innovations and be able to switch to them easily at a later date. A further development in the electrolysis module cools the hydrogen to 5 °C. This makes it possible to take in four to five times the amount of gas, because the moisture is now removed before storage.
New are also status displays that, at the touch of a button on the device or via the app, provide information about important system and storage statuses. The system always consists of an energy center and a hydrogen storage tank with a compressor that is installed outside the house on a concrete foundation. This foundation is absolutely essential.
The energy center unit has slimmed down considerably and now weighs 70 percent less: instead of 2.2 metric tons, now only 700 kilograms (1540 lbs). Reason is the switch from lead-acid to lithium batteries from the company Pylontech. The overall height has also reduced by 15 centimeters compared to its predecessor to 1.85 meters (6.07 ft). Doesn’t sound like much, but can be decisive for installation in a basement.
The Picea 2 costs at minimum 99,900 euros
The Picea module converts the surplus solar power in summer into hydrogen. In this way, large amounts of energy can be stored efficiently and over long periods of time. In winter, the gas, via a fuel cell, can be converted back into electricity and heat. The long-term storage capacity is up to 1,500 kilowatt-hours of electricity. In the smallest version with 16 gas cylinders, it is 300 kilowatt-hours.
The smallest version of the Picea 2 costs 99,900 euros. The gross price is the same as the net price, as the sales tax for the device, including storage units, is zero percent. With more storage capacity, the cost rises to up to 140,000 euros. This applies to a new construction where the installation can also be planned. In existing buildings, it can be a bit more complicated, so the amount may increase to up to 160,000 euros.
The demand seems to be there. Because over 500 devices of the first generation have been sold to date. More than 100 are installed at customers’ spaces.
