Abstract

Hydrogen energy storage, as a new type of energy storage with zero carbon emission, multi-energy federal reserve and combined supply, has a good development prospect in the integrated energy system. Based on the integrated energy system with hydrogen storage equipment, this paper proposes the operation mechanism of the integrated energy system with hydrogen storage equipment in the environment of electricity market and carbon market. On this basis, considering the time value of money, the life-cycle economic evaluation model of the integrated energy system with hydrogen storage equipment is constructed. The model is applied to calculate the investment benefit of a community integrated energy system with hydrogen storage equipment in the whole life cycle. The result of an example shows that the integrated energy system with hydrogen storage equipment is of good economic benefits.

Highlights

  • In the context of "carbon peaking", "carbon neutral" and large-scale new energy applications, hydrogen energy storage has the characteristics of zero carbon emission,multi-energy federal reserve and combined supply, which help improve the utilization rate of new energy and the stability of power system operation[1]

  • In order to measure the economics of an integrated energy system with hydrogen storage equipment, this paper takes a community-based integrated energy system with hydrogen storage equipment as an example and conducts a full life-cycle cost-benefit calculation of an integrated energy system with hydrogen storage equipment participating in carbon trading

  • The three items with the greatest sensitivity to Net present value (NPV) are all related to hydrogen, indicating that the cost of hydrogen production, hydrogen storage and the price of hydrogen sales are very important in the integrated energy system with hydrogen storage equipment which will have a large impact on the economics of the integrated energy system with hydrogen storage equipment

Summary

Introduction

In the context of "carbon peaking", "carbon neutral" and large-scale new energy applications, hydrogen energy storage has the characteristics of zero carbon emission,multi-energy federal reserve and combined supply, which help improve the utilization rate of new energy and the stability of power system operation[1]. Literature [4] puts forward the optimal allocation model of hydrogen energy storage units in the park integrated energy system with the optimization objectives of investment and operation cost and carbon emission. Most of the existing studies focus on the cost analysis of comprehensive energy systems containing hydrogen storage, and few studies analyze the income composition of such comprehensive energy systems in the market environment and calculate the economic benefits in the whole life cycle. 3.2 Revenue analysis In the environment of electricity market and carbon market, the integrated energy system with hydrogen storage equipment can supply electric energy, hydrogen energy, thermal energy and methane to users, and its carbon emission reduction can participate in carbon trading. Considering the time value of funds, the calculation of life cycle economic benefits of comprehensive energy system including hydrogen storage equipment is shown in formula (1)
