Our planet is a place worth preserving and protecting for the future. BORSIG is therefore constantly developing and improving processes that reduce the impact on the environment and protect natural habitats.
Our energy transfer and energy recovery products not only help maintain a healthy level of corporate profitability, they are our contribution towards making the key ecological and social goals of the energy transition a success.
It’s about nothing less than transforming the largest economic sector in the world – the energy industry – into one that is sustainable, secure and affordable for everyone.
Even now, the global energy landscape is rapidly changing and both the energy and climate policy goals demand a fundamental transformation of the current energy system. The actions of governments and major corporations are therefore crucial and have a serious impact on every sector. The economic investment decisions alone will amount to hundreds of billions of euros.

If you care as much about the future as we do, get in touch. We look forward to talking to you.
However, the various energy scenarios can only describe a possible development and are not forecasts. Oil is therefore likely to retain its role as the economically most important source of energy in the coming decades, but which alternative will “win the race” going forward is simply not foreseeable.
In a greenhouse gas-neutral energy system, for example, electricity generated from renewable sources will be the most important form of energy.
The electricity can be used directly (e.g. for electric mobility or heat pumps) or converted into electricitybased sources of energy (such as synthetic energy sources like power-to-gas or power-to-liquid).
Whatever answers we find to the question of energy, huge efforts are required.
As an international company, we are keenly aware of our role in finding these answers – and have been for many years. Our engineers, workers and managers are working together to play our part in making the economy more sustainable.
We, too, need to keep learning and making progress step by step – we will not depart from the path we have already been following for a long time and continue helping to make the world a little better within our means.
Hydrogen is set to play a pivotal role in the energy mix of the future. With the development of a new, oilfree compressor, BORSIG is helping to create the required infrastructure.
The transition to a green hydrogen industry is currently being driven forward at full speed, but before hydrogen can be used on the desired scale, a number of technical challenges still need to be resolved. These issues are the key focus of the MegaLyseurPlus joint research project, in which BORSIG is involved.
The aim of the project is to optimise the individual components of an electrolysis plant in order to make them fit for economic use in large-scale plants generating several megawatts of power. One of the focal points of MegaLyseurPlus is to develop an oil-free compressor for hydrogen. It serves as an interface to end applications, such as the refuelling of fleet vehicles, and to protect the new, eco-friendly propulsion systems, such as fuel cells.
In many compressors, lubricant oils are used in the gas chamber, some of which get into the gas.
However, hydrogen may not be contaminated if it is to be used in sensitive fuel cells. Therefore, up to now, oil-free membrane compressors and, more rarely, hydraulic compressors have been deployed. The disadvantage of membrane compressors is that they are prone to malfunction when operated irregularly, a process that is also difficult to predict.
Maintenance is very time-consuming and cost-intensive. Hydraulic compressors, on the other hand, are very small and only capable of processing small amounts of hydrogen.
The task for BORSIG was to develop a new type of compressor that would meet the requirements of larger hydrogen tank and transport systems in terms of both wear and performance.
Instead of using membranes or hydraulics, BORSIG opted to develop a piston compressor, which is based on technology known from the natural gas sector and that has now been implemented on an oil-free basis and thus hydrogen-compatible for the research project. In the course of development, BORSIG also increased output pressure from the originally envisaged 350 bar to 450 bar.
The advantages of the oil-free piston compressor over the current alternatives are quite considerable. The new piston compressor has a slightly higher output than a membrane compressor and a maintenance requirement that is easy to plan.
The standardisation of components was also part of the project, which promises further savings potential during regular operation going forward. A prototype of the compressor is still undergoing a final series of measurements until the end of 2022. After that, nothing will stand in the way of its deployment in the transformation to a green hydrogen economy.
