From March 29th to 30th, 2025, the 2025 International Conference of Renewable Energy & Heating Technology, hosted by the National Solar Thermal Energy Industry Technology Innovation Strategic Alliance, commenced grandly at Handan, Hebei Province. Professor Qi Pengcheng, General Manager of Hotran is invited to attend and delivered a keynote speech titled "Green Factory Practices: Energy Transformation and Innovation at the Budweiser Xinxiang Brewery." The presentation systematically explains the company's cutting-edge achievements in promoting large-scale applications of renewable energy within the industrial sector.

Focusing on the "Dual-Carbon" Strategy to Outline the Energy Transition Blueprint

The conference, themed "Green Thermal Energy: Driving the Future", brought together over 350 participants, including leaders from the National Energy Administration, Hebei Province government, as well as experts and scholars from domestic and international universities and research institutes. In the opening remarks, Qiao Yong, Director of the New Energy and Renewable Energy Department of the National Energy Administration, emphasized that renewable energy heating is a core pathway to achieving the "dual-carbon" goals. It’s necessary to strengthen technological research and regional collaboration. Academician He Yaling of the Chinese Academy of Sciences highlighted that technologies such as industrial medium- and low-temperature heat utilization and solar seasonal thermal storage will become key points for future development. 

Hotran Unveils "Trinity" Zero-Carbon Solution

In the report, Prof. Qi gives a deep analysis of the green transformation case at the  Budweiser Xinxiang Brewery. Through a multi-energy complementary model integrating "Photovoltaic + energy storage + solar thermal," the brewery increased its clean energy usage from 10% to 52%, enhancing overall energy efficiency by 40%.

 Photovoltaic System: 3.6 MW rooftop photovoltaic installation generates 3.3963 million kW annually, covering7% of the brewery's electricity demand and reducing carbon emissions by 1,936 tons per year.

 High-Temperature Heat Pump: Innovative programslike "ice-water linkage" and "washer and Pasteurizer interconnection" achieve a 75% waste heat recovery rate, replacing 16,742 tons of steam consumption annually and cutting carbon emissions by 2,085 tons.

 Parabolic Solar Thermal System: As the first solar thermal project in China's brewing industry, it replaces 3,400 tons of steam per year andreducing carbon emissions by 424 tons annually.

Prof. Qi also notes that this model is reproducible in high-energy-consuming industries such as food and beverage, textile dyeing, and printing, offering a customized best Solution for different industries.

Industry Recognition and Future Perspective

Hotran 's innovative practices received high praise from attended experts. Su Yanhua, Vice Mayor of Handan City, pointed out that the company's technology synergizes with Handan Kunle Bay's "solar thermal + cultural tourism" project, jointly promoting scenario-based applications of new energy. Hu Runqing, an expert from the Energy Research Institute of the National Development and Reform Commission, asserted that coupling industrial waste heat recovery with renewable energy is a core direction for decarbonizing.

Prof. Qi proposes three strategic directions from long-term perspective:

 Technological Breakthroughs: Developing high-temperature liquidsalt as working fluids and high-reflectivity coatings to enhance solar thermal system efficiency.

 Model Innovation: Establishing a multi-energy complementary system integrating "Photovoltaic+ heat pump + solar thermal + energy storage" to reduce energy dependence.

 Policy Coordination: Advocating for including"solar thermal + energy storage" in green electricity trading and exploring mechanisms for reinvesting carbon quota revenues.

Hotran will continue to drive green transformation through technological innovation, assisting the industrial sector in achieving the "dual-carbon" goals and contributing Chinese solution to the global energy revolution.
