INNOVATION
We have innovated in affordable, robust and expandable energy recovery devices for small-scale applications.
SUPER FEATURES
We have designed a maintenance-free high-pressure expander, which enables industrial applications for the migration to green energy.
IMPACT
We can potentially install millions of small-scale efficient systems for energy recovery and green energy integration.
Industrial applications with a big impact
Integrating sustainable solutions for the transition of gas networks
Innovation for gas based systems and processes



We love thermodynamics innovations
Our system, in simple terms, allows the production of work, cold and electricity from pressure energy. This can be as complex as turning a gas into a liquid or as simple as allowing a change in pressure...
HIGH PRESSURE ENERGY RECOVERY
Focusing primarily on recovering energy from natural gas networks to do useful work that reduces the energy bill of gas networks in lieu of expensive equipment.
LINEAR GENERATORS
Innovative energy production for local applications by transforming the work of the expander into electricity.
THERMODYNAMICS SYSTEMS
Alowing gases to be liquified in open or closed loops for low termperatures industrial applications.
FREE PISTON EXPANDER
Our linear expanders are capable of working at varying pressure ratios. This allows us to operate at exceptional capacities while providing affordable and durable solutions.
CASE STUDY
Energy Potential of Networks
Gas networks need energy efficiency and new revenue streams, as well as the technological capabilities to adapt to future changes. We can provide that with small expanders.
CHALLENGE
The cost of developing and maintaining turbines makes them difficult to use for small-scale processes.
OPPORTUNITY
Gas networks must adapt to the integration of green energy gases such as biogas and hydrogen.
CASE STUDY
Small-scale gas liquefaction
As the need for small-scale decentralized production of industrial gases such as oxygen and energy gases becomes more and more pressing, we are here to provide an innovative solution.
CHALLENGE
The cost of developing and maintaining turbines makes them difficult to use for small-scale processes.
OPPORTUNITY
Gas liquefaction has enormous potential for green energy applications using biogas and hydrogen.
Applications Portfolio
Gas-based systems using compression, expansion and high-pressure thermodynamic cycles can benefit from our technological innovation to improve their processes.
