How does Power-to-X support decarbonization?
By converting electricity into other forms of energy, Power-to-X gives us a way to store electricity in new forms. For example, power can be converted via electrolysis into hydrogen gas, which can be stored or used directly. It is a good fuel in pure form or can be combined with other elements to produce E-fuels or chemicals. Power-to-X is an essential element in the green transition because it facilitates storage of energy from renewable sources, for example in the form of green hydrogen from split water.
Applications
Since all energy for electrolysis is converted from AC to a variable DC, there is a need for intelligent and reliable power conversion, which Danfoss can provide. To reach the greenest hydrogen gas production, the electrolyzer must also be highly energy efficient. Danfoss power converters offer the highly efficient and flexible power conversion required to run these demanding applications – and they also support many auxiliary applications in power-to-x.

During the electrolysis process (using an electrolyzer), excess heat is produced as a by-product and can be utilized by other sectors. In Fredericia, Denmark, the HySynergy project is reshaping the energy landscape through a partnership between green hydrogen producer Everfuel and local district heating company TVIS. This project aims to leverage excess heat generated from Everfuel’s green hydrogen production and supply it to local households. The HySynergy project will convert renewable electric energy for Everfuel’s own hydrogen refueling stations, to hydrogen produced for the neighboring Crossbridge Energy refinery, as well as supplying surplus heat to the local district heating system. The project is ideally situated to supply hydrogen for the pipeline planned to connect European countries, in future years.

Danfoss helps you stay on target from the start. With huge investments involved, and CO2 target deadline to meet, there isn’t much room for experimentation, and failure is not an option. Therefore, it is necessary to choose the right solutions from the beginning. Danfoss technology has been developed and refined to deliver future-proof, guaranteed performance with many added features to lower risk and ensure a stable operation. You can trust that with Danfoss solutions you can be sure that you have made the right choice from the beginning with better total economy and peace of mind for operational excellence of each electrolyzer in your electrolysis plant.
Your hydrogen production electrolyzer must be highly energy efficient in every aspect. This applies to the power conversion to match your stacks, the pumps that supply your water, the heat exchangers that recover your excess heat and your valves and sensors that control it all. Danfoss can help you with the big picture.
Let us take care of your power supply. Power conversion is a complex task. At Danfoss we support OEMs and system integrators with certified intelligent power conversion solutions based on intelligent low-voltage drives, saving time, cost and effort in testing and certification.
We design our heat exchangers in close cooperation with our customers to perfectly match the thermal requirements of any duty. Throughout the years we have developed what has become the largest plate portfolio in the world. Having an option for every application and duty enables us to fine-tune each solution to the specific task at hand.

One green method to produce hydrogen is through the electrolysis of water, using an electrolyzer. . It requires ultra-pure water to ensure the efficiency and longevity of the electrolyzer. In the electrolyzer, electrical energy breaks water molecules into hydrogen and oxygen gas. Production of ultra-pure water can in coastal areas come from SWRO. For electrolyzers and SWRO we offer high-pressure pumps and energy recovery devices.
To achieve an electrified world, industry requires solutions that maximize energy efficiency from renewable sources when capacity is high and convert into firm clean energy for use when capacity is low. That requires high efficiency power conversion with low harmonic distortion while ensuring global scalability and cost-effectiveness.
As Power-to-x and electrolyzer applications increasingly integrate into the energy infrastructure of communities, they are of more interest to hackers. Here, Danfoss supports you in repelling cyberattacks with unique hardware-based cybersecurity.
Today, engineers increasingly speed up and de-risk their design processes by putting simulation to work. Danfoss helps you to reduce complexity in simulation of test and commissioning with a range of integrated facilities management (ifm)-compatible component models and simulation tools.
Case stories
DENMARK: The Everfuel HySynergy facility produces green hydrogen with the help of iC7-Hybrid power converters for efficient, cost-effective electrolysis.
News
Danfoss Drives are announcing the acquisition of the ACE300 product and the takeover of the product team from Finland-based company Ampner Oy, to extend the electrification portfolio with a dedicated 1500 VDC power converter. The product will be integrated within Danfoss Drives’ portfolio of Electrification Solutions with primary focus on Smart Grids and energy storage.
Fuels of the future
Apart from green hydrogen, other potentially sustainable fuels of the future are methanol and ammonia Each of the fuels has its committed defenders and detractors. However green hydrogen is the most likely contender, since it is produced from renewable energy using electrolysis. Green hydrogen can be used in the form of fuel cells or in internal combustion engines. Hydrogen is already used in buses for public transport. In the maritime sector, hydrogen is a fuel best suited to fuel cells, charging batteries onboard battery-electric short-sea ferries, to extend their range.
