Company's "Energy-Harvesting Coal Pile Thermal Safety Technology Based on Gravity Heat Pipes" Successfully Passes Scientific and Technological Achievement Appraisal

On November 10, 2025, the project "Research and Application of Key Technologies for Energy-Harvesting Coal Pile Thermal Safety Based on Gravity Heat Pipes" — led by Guangzhou Bluesky Thermovoltaic Micro-Energy Technology Co., Ltd., in collaboration with Guangzhou City University of Technology, Guangzhou Institute of Measurement and Testing Technology, and other partner institutions — successfully passed the scientific and technological achievement appraisal organized by the Guangdong Energy Conservation Engineering Technology Innovation Promotion Association at 

Guangzhou City University of Technology.

The appraisal committee unanimously concluded that the overall technology of this achievement has reached an internationally advanced level and approved its formal acceptance.

Innovation-Led: Building a Closed-Loop System of "Extracting Heat from Coal, Powering Monitoring with Heat"

Centered on the persistent industry challenge of coal pile spontaneous combustion prevention and control, this project transcends conventional technological limitations to establish an integrated, autonomous closed-loop system encompassing efficient heat dissipation, passive self-powering, and intelligent early warning.

By actively extracting internal heat from coal piles via gravity heat pipes to prevent spontaneous combustion, and combining thermoelectric generation technology to realize the principle of "extracting heat from coal to power monitoring," the system leverages low-power energy management and advanced predictive modeling to achieve active heat dissipation alongside a remarkable 91.7% temperature prediction accuracy. This advancement facilitates a critical shift in coal yard safety management from reactive emergency response to proactive early warning.

Scenario-Driven: Actively Responding to National Policies on New Scenario Applications

Recently, the Implementation Opinions of the General Office of the State Council on Accelerating Scenario Cultivation and Opening to Promote Large-Scale Application of New Scenarios (Guobanfa [2025] No. 37) explicitly called for promoting pilot trials of new technologies in typical scenarios to accelerate the transformation of scientific and technological achievements and industrial upgrading.

The energy-harvesting coal pile thermal safety system developed by our company represents a vivid embodiment of the "scenario-driven innovation" philosophy. The system has been successfully deployed across multiple operational scenarios — including enclosed circular coal yards (Huaneng Dongfang Power Plant), open-air strip coal yards (Huaneng Ruijin Power Plant), and enclosed strip coal yards (Huizhou Port) — demonstrating excellent reliability, economic viability, and scalability.

Broad Prospects: Enabling Extreme Environment Monitoring Across Multiple Industries

This technology is not only applicable to thermal safety and prevention across various coal storage facilities but also holds significant potential for expansion into extreme industrial environments, enclosed equipment diagnostics, and distributed unattended monitoring networks. Its defining characteristics — passive, wireless, and weather-resistant — position it as an ideal alternative to traditional thermal management and localized power supply solutions, poised to establish a new intelligent monitoring ecosystem across energy, transportation, municipal infrastructure, and beyond.

Collaboratively Building a New Ecosystem for Smart Energy Security

Looking ahead, Guangzhou Bluesky Thermovoltaic Micro-Energy Technology Co., Ltd. will steadfastly uphold the principle of "technology-driven, scenario-empowered, open and win-win." We will continue collaborating with energy enterprises, design institutes, equipment manufacturers, and other partners to co-build an ecosystem integrating industry, academia, research, and application. Our goal is to promote the standardization and large-scale deployment of micro-energy technologies, injecting new momentum into China's energy security, industrial intelligence, and green development initiatives.
