The innovative Czech company RSE s.r.o. has joined the Energy Club. It is a leading manufacturer of cogeneration modules and an official partner of Caterpillar Energy Solutions and the German brand MWM. The company operates steadily in both European and Ukrainian markets. Over the past two years, RSE s.r.o. has produced over 200 custom energy modules. In March, under contract No. 30/01 dated February 12, 2025, it delivered five cogeneration units, each with a capacity of 2.3 MW, to Kharkiv. The units are based on German MWM engines and provide simultaneous generation of heat and electricity, which is critically important for infrastructure facilities under shelling.
RSE wins tenders due to its high-quality equipment, speed of delivery, and competitive prices, making the company a notable player in the Ukrainian market.
Andrii Grinenko, founder of RSE s.r.o., spoke to the Energy Club’s media department about the company’s activities, achievements, strategic goals, the role of innovation in its development, expectations from cooperation with the Energy Club, and the situation in Ukraine’s energy sector:
— RSE is a Czech engineering company with Ukrainian roots, specializing in mobile solutions for autonomous energy. We develop and manufacture high-efficiency cogeneration modules with a capacity of up to 4.5 MW and innovative industrial heat pumps based on turbocompressor technology with the natural refrigerant R290.
Our solutions are already helping communities, industrial enterprises, and government institutions guarantee energy resilience—regardless of external challenges, military risks, or grid instability. We implement fully turnkey solutions in 7–10 days, adapted to the needs of critical infrastructure.
RSE is an official partner of MWM / Caterpillar—one of the most powerful players in the global energy technology market. This partnership allows us to combine local flexibility and speed with global standards of quality, reliability, and service.
Our goal is to create a next-generation European energy ecosystem where decentralization = resilience, and each module is a contribution to a strong and secure infrastructure.
— What are the company’s proudest achievements?
— We have already supplied approximately 400 MW of solutions for critical infrastructure throughout Ukraine. We are trusted by industry leaders, including Ukrzaliznytsia, Epicenter, UPG, Ukrnafta, MHP, Farmak, Vatsak, and others.
And today, we are opening a new front of energy efficiency—RSE heat pumps with turbocompressor technology using a natural refrigerant.
A Coefficient of Performance (COP) of up to 7.2, the absence of a bearing assembly, friction, oil, and minimal maintenance needs—all this makes them an ideal choice for municipalities, hospitals, agricultural complexes, and logistics hubs. Moreover, an industrial heat pump combined with our cogeneration module increases the unit’s efficiency by 40%, which is extremely important for utility and municipal enterprises.
— What are your strategic goals for the next 1–3 years?
— Building a large-scale production and service infrastructure in Europe and Ukraine. — Widespread implementation of cogeneration and heating solutions at critical infrastructure facilities. — Entering new markets with our heat pumps—primarily in Central and Eastern Europe.
— What was the main incentive to join the Energy Club?
— For a company that creates real solutions for the energy transition, it is important to be in an environment of like-minded people. We see the Energy Club as a platform for collaboration, jointly finding answers to energy challenges, and expanding the market for new technologies—including heat pumps.
— What results do you expect from cooperation with the Club?
— Engaging Ukrainian partners in joint projects on energy efficiency and decentralized energy. — Promoting alternative heat sources, particularly heat pumps that use low-potential heat from cogeneration units. — Expanding partnerships around our Energy Resilience Lab initiative at KPI (Igor Sikorsky Kyiv Polytechnic Institute)—as a platform for implementing, training, and testing modern energy resilience technologies. — Joining forces with Club members to jointly present Ukrainian innovations at the international level.
— How do you assess the current situation in Ukraine’s energy industry?
— Ukraine’s energy system is going through a period of unprecedented challenges—from direct attacks on infrastructure to threats to its energy independence. But at the same time, we see a unique window of opportunity: a new energy architecture is being laid right now—more flexible, decentralized, and based on a combination of generation and energy storage.
Our industrial heat pumps are part of this transformation. They allow for the efficient use of surplus heat, geothermal, and atmospheric sources, combining with cogeneration modules into a single system. This is not just energy efficiency. This is a new standard.
— What role do innovations play in RSE’s development, and what are you focusing on in the coming years?
— Innovation is in our DNA. We don’t just adapt existing solutions; we create our own technologies at the intersection of engineering, ecology, and energy.
A prime example is our RSE heat pumps with an oil-free turbocompressor using the natural refrigerant R290, which has a Global Warming Potential (GWP) of 3. They achieve a COP of up to 7.2 and require no technical intervention for over 10 years. Compared to traditional systems, this is a true revolution in heat production.
We aim to be a leader among energy innovators in Central and Eastern Europe. We already have our own production and testing center in the Czech Republic, and we are building the Energy Resilience Lab in Ukraine—as a space for developing new products, pilot projects, and training specialists.
Industrial heat pumps are our next big wave. We want every new school, hospital, or logistics center in Ukraine to have access to systems that generate heat ecologically, efficiently, without emissions, and with minimal costs. And this is not the future—it is already happening.
