Recently, Hubei Green Cold Hi-Tech Group Co., Ltd. (hereinafter referred to as Green Cold Hi-Tech) officially signed a cooperation agreement with Hungary’s Kap Group. This marks not merely a business partnership between the two enterprises, but another tangible achievement as China’s green and low-carbon technologies go global. Centered on the overseas export of green technologies, Green Cold’s air-source heat pumps serve as a vivid example of green development under the Belt and Road Initiative.
Extreme cold regions demand robust green solutions
Located in the heart of Central Europe, Hungary is affected by Black Sea storms in winter, with temperatures dropping to nearly minus 30 degrees Celsius. For a long time, coal and other traditional energy sources have dominated residential winter heating in the country. Like Poland and the Czech Republic, Hungary faces severe air quality challenges stemming from solid-fuel heating among residents, with coal remaining one of its primary fuel sources.
Against the backdrop of accelerated energy transition across the European Union, Hungary’s demand for clean heating technologies has been rising rapidly. As an efficient electrified heating technology, air-source heat pumps represent a critical alternative to fossil-fuel-based heating.
Green Cold Hi-Tech delivers proven Chinese solutions capable of withstanding extreme cold.
Leveraging self-developed nano eco-friendly refrigerants and its multi-connection and multi-supply system, Green Cold’s air-source heat pumps maintain stable heating performance in frigid environments, with energy efficiency far exceeding domestic and international standards. The reliability of this technology has been repeatedly verified through large-scale domestic application practices.
From China’s Coal-to-Electricity Program to the Belt and Road: Technology Takes Root, Experience Goes Global
Green Cold Hi-Tech’s strengths originate from real-world practices in China.
The large-scale coal-to-electricity clean heating project implemented across northern China has created the world’s largest testing ground for air-source heat pump technologies. Since 2016, clean heating has been listed as a key livelihood project and advanced under the principle of prioritizing gas or electricity based on local conditions. During this process, air-source heat pumps, boasting cleanliness and high efficiency, have become a core technological alternative to bulk coal combustion.
It was within such field practices that Green Cold Hi-Tech developed its multi-connection and multi-supply system. Built upon heating, cooling and ventilation equipment and renewable energy sources, the system enables automatic switching between cooling, heating and hot water supply via pipeline layout and control panels, achieving industry-leading comprehensive energy efficiency ratios. The system’s adaptability and stability have been tested under complex operating conditions, ranging from heating for individual households to community central heating, rural coal-to-electricity projects and urban gas-to-electricity initiatives.
Today, this Chinese expertise is being brought to Central and Eastern Europe along the Belt and Road.
Kap Group of Hungary chose to partner with Green Cold Hi-Tech precisely for its fully validated technological maturity and reliable performance under extreme cold working conditions. For Hungary, Green Cold brings not just products, but replicable and customizable clean heating solutions.
Overseas export of green technologies aligns with the underlying logic of the Belt and Road
Green Cold Hi-Tech’s entry into Hungary is well-timed.
In 2022, four authorities including the National Development and Reform Commission issued the Opinions on Promoting Green Development under the Belt and Road Initiative. The document explicitly calls for deepening cooperation on green and clean energy, advancing the green and low-carbon transition of international energy cooperation, and encourages enterprises to go global to deliver best-practice green energy projects. It specially highlights that green development should serve as the defining feature of the Belt and Road Initiative.
The cooperation between Green Cold Hi-Tech and Hungary’s Kap Group offers a lively sample for this national policy.
Technically, Green Cold’s heat pump nano eco-friendly refrigerants stand at the cutting edge of refrigerant technology. The typical traits of fourth-generation refrigerants include an extremely low global warming potential (GWP) and negligible ozone depletion potential (ODP), delivering outstanding environmental performance. Green Cold adopts self-developed nano eco-friendly refrigerants whose environmental indicators meet the world’s strictest standards. This means its products can avoid green trade barriers when entering overseas markets and instead gain environmental advantages.
From a market perspective, Europe’s heat pump market is witnessing policy-driven growth. The European Union has set a strategic target of reaching 60 million heat pumps in stock by 2030. In 2024, the installed base stood at 25.537 million units, leaving a gap of over 34 million units. Countries such as the United Kingdom and Germany have recently ramped up heat pump subsidies; Germany’s maximum subsidy rate for heat pumps can reach up to 70%. China’s heat pump exports have maintained year-on-year growth for 20 consecutive months, hitting 16.46 billion RMB in export value for 2025.
By entering the Hungarian market at this juncture, Green Cold keeps in step with policy trends and seizes market opportunities.
Made by China, Serving the World
“Green Cold, invented in China, serves the world.” This brand declaration encapsulates its development philosophy.
Drawing on practical experience accumulated through China’s domestic coal-to-electricity campaign to deliver customized overseas solutions; relying on self-developed nano eco-friendly refrigerants and the stable performance of its multi-connection and multi-supply system under extreme cold conditions — Green Cold Hi-Tech is building a bridge for green cooperation with cutting-edge technology.
At one end of this bridge lies China’s technological expertise and industrial capacity developed in clean heating; at the other end are the genuine needs for green and low-carbon development among countries along the Belt and Road.
When Hungary’s cold winter winds meet Green Cold’s heat pumps, what flows is not only heat but also shared wisdom for pursuing carbon peaking and carbon neutrality goals. Within the grand narrative of green development under the Belt and Road Initiative, stories like this are materializing through one cooperative project after another.
Green is becoming the most distinctive hallmark of the Belt and Road Initiative. As a pioneer, Green Cold Hi-Tech continues to brighten this hallmark.
