Research project: H2E - Hydrogen to Energy

X2E-SE Team — Thu, 17 Jul 2025 11:28:45 +0000

Applicant: X2E System Engineering GmbH
Funding code: EP201233
Duration: 01/2023 – 08/2024

Motivation

The aim of the H2E project was to develop and test an intelligent energy management system (EMS) for hydrogen systems. In view of the complexity and dynamic requirements of hydrogen systems – from generation and storage to reconversion into electricity – the core motivation was to create a flexible and efficient control solution. This should simplify the planning and operation of such systems, particularly with regard to the integration of renewable energies and the optimization of the energy flow.

Hydrogen pilot plant

To test the EMS, the hydrogen pilot plant (Fig. 1) was planned from scratch and installed in a 10-foot container, supplemented by an external fittings cabinet for the fluid technology and central sensors. The core of the plant is an AEM electrolyzer for hydrogen production including a downstream dryer unit. A compressor and a cylinder bundle, supported by a buffer tank, are used to compress and store the hydrogen at up to 300 bar. The stored hydrogen is converted back into electricity using a fuel cell.

Energy management system

The developed energy management system (EMS, Fig. 2) forms the central control instance and thus the “brain” of the hydrogen pilot plant. Its architecture is divided into two main components: a service component (with central database, REST API, React-based web front end for system configuration) and a customer component (with local database, REST API, multi-platform app for monitoring and control by end users). The EMS is characterized by high functional flexibility, in particular by the manufacturer-independent abstraction, integration and utilization of Modbus-capable devices of various types. The energy flows are controlled via individually definable trigger mechanisms, consisting of sensor, limit value and assigned action. These triggers form the decision logic of the EMS and enable an adaptive, status-dependent reaction to variable operating conditions. A mini PC serves as the hardware platform, which is operated in close
coupling with the H2 system control unit to ensure direct, fast-reacting system control.

Conclusion & outlook

The development and integration of the energy management system into the hydrogen pilot plant was successfully completed.
All functions were implemented as planned and put into operation in conjunction with the plant technology. The modular and flexible system architecture enables efficient, scalable control and continuous monitoring of the entire hydrogen process. In the future, the EMS will play a central role in the integration of future
hydrogen plants in order to optimize the use of green energy.

Investing in hydrogen - opportunities and risks

X2E-SE Team — Fri, 04 Jul 2025 13:34:17 +0000

Whether industry, mobility or energy storage – the importance of and demand for hydrogen will increase rapidly in the coming years. For companies, investors and project developers, entering the hydrogen economy offers enormous opportunities – but also challenges.

In this article, we shed light on the economic potential, highlight relevant areas of investment and assess the risks that need to be considered.

Why hydrogen?

With the global goal of climate neutrality, CO₂-free technologies are increasingly coming into focus. Hydrogen enables decarbonization where electrification reaches its limits – for example in the steel industry, chemical production or heavy goods transport. According to the EU Commission and the IEA, global hydrogen demand will increase 6 to 10-fold by 2050. The National Hydrogen Strategy also anticipates massive expansion in Germany – especially for green hydrogen.

Investment opportunities

Generation & Infrastructure

The investment opportunities along the hydrogen value chain are diverse. Particularly in the area of production and infrastructure, there are opportunities in the construction and operation of electrolysers powered by renewable electricity. There are also technologies for the storage, compression and distribution of hydrogen as well as the construction of entire H₂ hubs, energy parks or offshore projects.

Technology & components

At a technological level, developments in fuel cell technology, the production of hydrogen filling stations, valves and digital control systems are in demand. Automation and digitalization are also playing an increasingly important role.

Applications & markets

New application markets are emerging through the conversion of industrial operations, particularly in energy-intensive sectors such as steel, glass and chemicals. In the transport sector, hydrogen-powered trucks, trains, ships and even airplanes are increasingly coming onto the market. At the same time, hydrogen is being integrated into energy systems, for example through power-to-gas applications or intelligent sector coupling.

Subsidies as a catalyst

The investment landscape is flanked by extensive public funding programs, e.g:

IPCEI Hydrogen (Germany & EU)
KfW promotional loans & investment grants
Clean Hydrogen Partnership (EU)
Innovation fund and national transformation programs

These subsidies reduce market risks and accelerate the profitability of new projects.

Risks and challenges

Despite all the potential, however, the hydrogen economy remains fraught with challenges. From a technological perspective, these include the still high production costs – especially for green hydrogen – complex plant technology in some cases and a lack of standardization. From an economic perspective, there are risks due to the dependency on the price of electricity and subsidies, as well as uncertain economies of scale in the development of demand. International competition, particularly with cheap imported hydrogen, must also be taken into account. In regulatory terms, the market is in a constant state of flux – EU directives, national legislation and CO₂ pricing have a direct impact on projects and business models. The timely development of a suitable infrastructure will also be decisive in determining whether potential players gain access to the market at all.

Conclusion

In summary, it can be said that investments in hydrogen offer great opportunities – for climate protection, for technological innovations and for opening up new markets. However, as with any future technology, the same applies here: Success requires sound planning, technical know-how and a good understanding of market and funding structures.

Development of hydrogen prices

X2E-SE Team — Fri, 04 Jul 2025 13:31:39 +0000

How expensive is hydrogen at the moment? What factors influence the costs? And how will prices develop in the future?

In this article, we take a look at the current price structure and provide an assessment of future developments.

Current hydrogen prices: Large differences depending on origin

The price of hydrogen depends heavily on the production method. A basic distinction is made between

Hydrogen type	Production method	Price range (2025)
Gray hydrogen	Steam reforming from natural gas	approx. 1.50 – 2.50 €/kg
Blue hydrogen	Like gray H₂, but with CO₂ capture	approx. 2.00 – 3.50 €/kg
Green hydrogen	Electrolysis with renewable electricity	approx. 4.00 – 8.00 €/kg

Current cost driver

The current cost drivers for hydrogen production – especially for green hydrogen – are diverse and have a significant impact on its economic viability. Electricity prices, which can account for up to 70% of the total costs of green hydrogen depending on the location and technology, make up the largest share. Added to this are the investment costs for electrolysers and the necessary infrastructure, such as compressors, storage or grid connections.

Economies of scale are another decisive factor: Larger plants can produce hydrogen much more cheaply, as the specific costs per unit fall as the production volume increases. Transportation and distribution costs also play an important role – these vary considerably depending on distance, infrastructure and aggregate state (gaseous, liquid or chemically bound). Finally, political and regulatory framework conditions have a significant impact on the cost structure. These include grid fees, levies, CO₂ pricing and subsidy measures, which can either reduce or increase costs.

Hydrogen prices tomorrow: where will the journey take us?

Experts from research, industry and international organizations such as the IEA, the EU Commission and the Fraunhofer Institute expect that green hydrogen will soon be much cheaper to produce – especially in regions with very cheap renewable energies. In countries such as Australia, North Africa or Chile, the price of green hydrogen could fall to less than 2 euros per kilogram by 2030. Wind and solar energy are so cheap and constantly available there that hydrogen can be produced economically on a large scale.

A cost parity between green and gray hydrogen is also expected in Europe – depending on the expansion of the infrastructure and the development of the CO₂ price. Estimates assume that this so-called “parity point” could be reached from around 2035. Rising CO₂ costs are making fossil production methods more expensive, while green technologies are becoming increasingly cheaper through scaling, automation and innovation.

Another building block is hydrogen imports: the development of international supply chains – by pipeline or ship – makes it possible to bring green hydrogen from particularly favorable production regions to Europe. The necessary infrastructure (e.g. the European hydrogen network) is already being planned or built.

Political measures as price drivers and price sinks

The economic viability of hydrogen does not depend solely on technical innovations and economies of scale – political framework conditions also have a significant influence on supply, demand and price development. Policymakers can actively promote and accelerate the market ramp-up of green hydrogen through targeted measures.
One key instrument is CO₂ pricing, which is making fossil fuels – and therefore also conventionally produced (grey) hydrogen – increasingly expensive. The higher the CO₂ price, the more attractive green hydrogen, which is produced entirely without greenhouse gas emissions, becomes in comparison.

At the same time, government funding programs and investment grants ensure that production facilities for green hydrogen become economically viable. Subsidies for electrolysers, infrastructure projects and research reduce initial costs and enable companies to bring new technologies to market faster.

In addition, politicians are creating targeted demand with so-called hydrogen lead markets – for example in industry, heavy goods transport and energy supply. Clear guidelines and long-term strategies create investment security for companies along the entire value chain. Anyone investing in hydrogen technology today can count on stable political support and a growing demand base.

Instruments such as the EU’s hydrogen bank or national tenders for subsidy premiums (“H₂ contracts for difference”) are also intended to help bridge the price gap to fossil alternatives.

Conclusion

The price of hydrogen is currently still heavily dependent on technology and location – and represents an economic challenge for many applications. However, with a growing market, technological progress and targeted subsidies, prices will fall noticeably in the coming years.

Climate protection with hydrogen

X2E-SE Team — Fri, 04 Jul 2025 11:15:44 +0000

Climate change is one of the greatest challenges of our time. In order to drastically reduce global CO₂ emissions and achieve the goals of the Paris Climate Agreement, far-reaching changes are needed in the energy, industrial and mobility landscape. Hydrogen plays a central role in this – as a versatile, clean energy carrier and key technology for a sustainable future.

Climate neutrality requires new solutions

Around three quarters of global greenhouse gas emissions are caused by the use of fossil fuels – in electricity generation, industry, transportation and heat supply. Many of these sectors cannot be fully electrified. This is precisely where hydrogen comes in:

As an emission-free energy source
As a storage medium for renewable energies
As a bridge between electricity, heat, industry and mobility

Green hydrogen: CO₂-free right from the start

The production of green hydrogen – through electrolysis with electricity from renewable energies such as wind, solar or hydropower – is crucial for climate protection. This process does not produce any CO₂. If this hydrogen is used instead of fossil fuels, even areas that are difficult to decarbonize can become climate-neutral.

Examples:

Steel production without coke
Truck traffic without diesel
Heat supply without natural gas

CO₂ savings through hydrogen applications

Depending on the application, the use of hydrogen can save significant amounts of greenhouse gases. Studies show that hydrogen could avoid up to 70 million tons of CO₂ per year in Germany alone – this corresponds to around a third of current industrial emissions.

Hydrogen as a link in sector coupling

A successful energy transition requires the linking of the electricity, heating, mobility and industrial sectors – so-called sector coupling. This is exactly what hydrogen makes possible: it can be generated from electricity, stored, transported and reused in a variety of ways – as a fuel, process gas or base material for synthetic fuels.

Conclusion

Hydrogen is a key building block for climate protection. It makes renewable energy storable, replaces fossil fuels in industry and transportation and brings the sectors together. With green hydrogen, we can drastically reduce CO₂ emissions – and actively shape the path to a climate-neutral future.

Hydrogen storage and transportation

X2E-SE Team — Fri, 04 Jul 2025 11:07:31 +0000

In order for hydrogen to be used as an energy carrier on a large scale, it must be stored and transported efficiently – whether from the production site to industrial plants, to filling stations or to the energy infrastructure. Various technologies are used for this, each of which has its own advantages and disadvantages. In this article, we present the most important methods: Pressurized tanks, liquid hydrogen, LOHC and pipelines.

Pressure tanks – compact and flexible

One of the most widely used forms of storage is compressed gas storage. Hydrogen is stored in specially reinforced containers at high pressure – usually at 350 to 700 bar.

Advantages:

Technologically proven and safe
Quickly available (e.g. for mobile applications such as fuel cell vehicles)
Modular use, also for decentralized supply

Areas of application: Hydrogen filling stations, mobile applications, transportation by truck

Challenge: The energy required for compression is relatively high, the volume remains larger than with liquid hydrogen despite compression.

Liquid hydrogen – high energy density through liquefaction

Liquid hydrogen (LH₂) is produced by cooling hydrogen to -253 °C, whereby the gas changes to a liquid state. This method enables particularly compact storage with a high energy density.

Advantages:

High energy density
Ideal for long-distance transportation and applications with high energy requirements (e.g. aviation, space travel)

Areas of application: Large filling stations, aviation, shipping, intercontinental transportation

Challenge: The extremely low temperature requires complex insulation and causes high energy losses during liquefaction.

LOHC – Liquid hydrogen carriers for safe storage

LOHC stands for Liquid Organic Hydrogen Carriers – liquid organic carrier substances that can chemically bind hydrogen. The hydrogen is incorporated into the carrier material (hydrogenation) and released again if required (dehydrogenation).

Advantages:

Storage and transportation at ambient pressure and temperature
Use of existing infrastructure (e.g. tank trucks, tank farms)
Low risk of explosion

Areas of application: Long-distance transportation, stationary energy storage, import solutions

Challenge: Releasing the hydrogen requires additional energy and special equipment.

Hydrogen pipelines – infrastructure for the future

Hydrogen pipelines are ideal for large-scale transportation over longer distances – either newly built or by converting existing natural gas pipelines.

Advantages:

Continuous supply to large customers (industry, chemicals, energy)
High transport capacity
Low ongoing operating costs

Areas of application: Industrial sites, hydrogen networks, cross-border transportation

Challenge: Establishing a suitable infrastructure, material requirements due to hydrogen embrittlement

Conclusion

The storage and transportation of hydrogen are crucial for a functioning hydrogen economy. Depending on the application, different technologies are used – from flexible pressure tanks and compact liquid hydrogen systems to large-volume pipelines and safe LOHC solutions.

How does a fuel cell work?

X2E-SE Team — Fri, 04 Jul 2025 09:59:18 +0000

The fuel cell is a key technology for the use of hydrogen as a clean energy source – whether in cars, trains, buildings or industry. But how exactly does a fuel cell work? In this article, we explain how it works and the advantages of this fascinating technology.

Basic principle: electricity from hydrogen and oxygen

A fuel cell converts the chemical energy of hydrogen directly into electrical energy – without combustion, almost silently and without harmful emissions. The only “waste product” is water vapor. The energy generated can be used directly to drive an electric motor, to supply electricity or to generate heat.

Structure and function of a fuel cell

A single fuel cell essentially consists of three components:

Anode (negative pole)
Cathode (positive pole)
Electrolyte membrane separating the two sides

This is how the process works:

Supply of hydrogen: Hydrogen gas (H₂) is supplied at the anode. There, catalysts split the hydrogen molecules into protons (H⁺) and electrons (e-).
Separation of protons and electrons:
- The protons migrate through the electrolyte membrane to the cathode.
- The electrons cannot pass through the membrane – instead they flow via an external circuit to the cathode, generating an electric current.
Reaction with oxygen: The electrons, protons and the oxygen (O₂) supplied from the air come together again at the cathode. Water (H₂O) is produced – in the form of water vapor.

Types of fuel cells

There are different types of fuel cells, depending on the application and the technology used:

PEM fuel cell (Proton Exchange Membrane): Frequently used in vehicles and for mobile applications. It works at low temperatures and reacts quickly to load changes.
SOFC (Solid Oxide Fuel Cell): High-temperature fuel cell, particularly efficient for stationary applications such as power plants or building supply.
AFC, MCFC, PAFC: Other types with special areas of application, e.g. in aerospace or industry.

Advantages of fuel cell technology

Zero emissions: Only water vapor is produced – no CO₂, particulate matter or NOx emissions.
High efficiency: Significantly more efficient than classic combustion engines.
Quiet operation: No moving parts such as pistons or turbines.
Versatility: Suitable for vehicles, buildings, emergency power supply and industrial applications.

Conclusion

The fuel cell enables the direct use of hydrogen – efficiently, quietly and emission-free. This makes it one of the key technologies for the energy transition and for a climate-friendly future.

Why does hydrogen play an important role in the energy transition?

X2E-SE Team — Fri, 04 Jul 2025 09:45:00 +0000

The energy transition requires a fundamental change in the way we generate, store and use energy. Alongside renewable energies such as wind and solar, hydrogen (H₂) is increasingly seen as a central element of this transformation. But why is hydrogen so crucial for a climate-friendly future? The answer lies in its versatile application potential – particularly in CO₂ savings, as a storage technology and for sector coupling.

CO₂ savings – decarbonization of areas that are difficult to electrify

Many areas of industry and mobility are difficult to electrify directly – such as the steel and chemical industries or heavy goods transport. Here, hydrogen offers a climate-friendly alternative to fossil fuels. If hydrogen is produced from renewable electricity using green electrolysis, its use is virtually CO₂-free.

Exemplary applications:

Steel production: hydrogen replaces coke as a reducing agent and enables almost emission-free production.
Industrial heat: In high-temperature processes, hydrogen can substitute fossil fuels such as natural gas.
Traffic: Fuel cell vehicles only emit water vapor and are a clean solution, especially in heavy traffic or shipping.

In this way, hydrogen can help to save millions of tons of CO₂ emissions per year – especially in sectors where alternatives are lacking.

Storage technology – balancing supply and demand

Renewable energies such as wind and solar are dependent on the weather and do not always generate electricity when it is needed. This is exactly where hydrogen comes into play as an energy storage medium. Surplus electricity from renewable sources can be converted into hydrogen using electrolysis and stored – whether in pressurized tanks, caverns or even in existing gas grids.

The stored hydrogen can later be converted back into electricity or used directly in industry, transportation and heating buildings. Hydrogen therefore makes a decisive contribution to security of supply and grid stability – a key building block for a resilient energy system of the future.

Sector coupling – connecting electricity, heat, mobility and industry

One of the biggest challenges of the energy transition is the intelligent linking of the various energy sectors. This is exactly what hydrogen makes possible: it can convert electricity from renewable sources into chemical energy and thus efficiently connect the electricity, heating, transportation and industrial sectors.

Examples of sector coupling with hydrogen:

Power-to-gas: surplus electricity is converted into hydrogen and fed into the gas grid.
Hydrogen heating systems: In combination with fuel cells, buildings can be efficiently heated and supplied with electricity.
Mobility: H₂ filling stations can convert surplus electricity into emission-free fuel for buses, trains and trucks.

This cross-sectoral use makes hydrogen a central link in the energy transition.

Conclusion

Hydrogen is much more than just an alternative energy source – it is a multi-talent that reduces CO₂ emissions, makes energy storable and connects different sectors.
