In the pursuit of “dual-carbon” goals—reducing both carbon emissions and carbon intensity—researchers have made significant strides in optimizing the economic and environmental performance of integrated energy systems (IES). A recent study, published in *Power Technology*, introduces a novel approach to low-carbon economic scheduling that could reshape the energy sector’s landscape.
The research, led by Dr. Ma Kai from the Key Laboratory of Renewable Energy Generation and Grid-Connected Technology at Xinjiang University, focuses on the diversified utilization of hydrogen energy within IES. The study addresses a critical gap in existing models: the often-overlooked energy losses during hydrogen production via power-to-gas (P2G) technology.
“Existing models frequently ignore the energy losses that occur during the hydrogen production process,” Dr. Ma explains. “Our study aims to rectify this oversight by integrating a heat recovery device into the two-stage conversion process of P2G, thereby minimizing energy waste and enhancing overall system efficiency.”
The proposed model incorporates several innovative components, including hydrogen-blended combined heat and power generation, P2G systems, hydrogen fuel cells, and hydrogen storage tanks. Additionally, the study establishes a mathematical model for demand response and a green certificate-carbon trading mechanism, which are crucial for the system’s low-carbon economic scheduling strategy.
One of the most compelling aspects of this research is its potential commercial impact. By optimizing the total system cost—including expenses on green certificate trading, carbon trading, coal-fired power generation, electricity procurement, and natural gas purchases—the model offers a viable pathway for energy providers to reduce operational costs while adhering to stringent environmental regulations.
“The results are promising,” Dr. Ma notes. “Our model reduces the total system cost by 55% and achieves the full utilization of wind power. This not only enhances the economic viability of IES but also significantly contributes to the reduction of carbon emissions.”
The implications of this research extend beyond immediate cost savings. By demonstrating the feasibility of integrating diverse hydrogen energy technologies into IES, the study paves the way for future developments in renewable energy utilization and carbon-neutral power generation. As the energy sector continues to evolve, such innovations will be instrumental in achieving global climate goals and fostering a sustainable energy future.
This groundbreaking work, published in *Power Technology*, underscores the importance of interdisciplinary research in driving technological advancements and shaping the energy landscape of tomorrow.
