Strategic Partnership in ORC Technology On January 22, 2025, Rockfin and Siemens Energy signed a cooperation agreement that marks a new direction in the development of innovative energy technologies. This partnership focuses on the implementation of ORC (Organic Rankine Cycle) systems, which are one of the key solutions for decarbonization and efficient utilization of thermal energy. For Rockfin, this represents another step in expanding its product portfolio following the success of last year’s launch of the HyVentive line, dedicated to hydrogen technologies. Siemens Energy, as a leader in the production of steam turbines and turboexpanders, gains the opportunity to further develop its core business, particularly in C-type turbines.
ORC Technology as the Foundation of Collaboration
What is ORC Technology?
ORC (Organic Rankine Cycle) systems are advanced technologies that convert thermal energy into electricity using an organic working fluid. These cogeneration setups can simultaneously generate both electrical and thermal energy, significantly enhancing overall efficiency. Unlike traditional steam cycles, ORC systems operate effectively with medium- and low-temperature heat sources below 350°C, making them ideal for:
- Waste heat recovery in energy, heavy industry, and district heating,
- Renewable energy sources such as biomass, geothermal energy, and large-scale solar systems.
Rockfin and Siemens Energy Partnership
Rockfin and Siemens Energy have joined forces to implement ORC systems with electrical production capacities ranging from 0.5 to 3 MW.
In Poland, this technology is particularly important due to the European Emissions Trading System (ETS), where high CO₂ emission fees significantly impact energy costs. ORC systems provide an opportunity to reduce emissions and lower electricity production costs by converting waste heat from industrial processes into electricity.
Scope of the Partnership
The agreement between Rockfin and Siemens Energy clearly defines their roles:
- Rockfin: Responsible for the comprehensive design, delivery, and installation of turnkey ORC systems, ensuring smooth commissioning and testing.
- Siemens Energy: Supplies high-performance C-type turbines, bringing advanced thermodynamic expertise to maximize system efficiency.
- Joint Service Support: Both companies will provide service for the systems through a global service network covering Europe and beyond.
Target Markets and Potential Customers
Initially, the partnership will focus on European markets, where both companies have established operations. Future expansion plans include North America, South America, and Africa. The primary customers for ORC solutions include:
- Energy operators,
- Industrial power producers,
- District heating companies seeking waste heat utilization and greenhouse gas emission reduction.
Key Benefits of the Collaboration
The Rockfin and Siemens Energy partnership offers multiple advantages:
- Technology synergy: Combining expertise to develop cutting-edge energy solutions,
- Cost efficiency: Reducing energy costs through waste heat recovery,
- Sustainability: Supporting decarbonization efforts and a cleaner energy future.
By working together, Rockfin and Siemens Energy are driving a sustainable energy transformation, where efficient utilization of thermal energy will play a crucial role in the decarbonization of industries and economies worldwide.
