By summarizing the characteristics of the global energy structure and China’s energy resource endowment, this study analyzes the historical context and opportunities for China to build an “energy powerhouse”, and proposes pathways and measures for its realization. It is indicated that the energy resource endowment in China is characterized by abundant coal, limited oil and gas, and vast renewable potential, coupled with an energy consumption structure characterized by high coal consumption, low oil and gas consumption, and rapidly growing renewable energy use. The “whole-energy system” approach that integrates multi-energy complementarity, green development, stable supply, smart utilization and carbon neutrality is an effective solution to addressing energy transition and energy independence. To build an “energy powerhouse”, China can follow the approach of the steady and orderly low-carbon development of fossil fuels, the safe and scaled development of new energy, the integrated development of a carbon-neutral “whole-energy system”, and the shared development of the “Belt and Road” energy corridor. The construction of an “energy powerhouse” should follow a “three-phase” strategic pathway: from 2025 to 2030, achieving peak primary energy consumption and “carbon peaking”;from 2031 to 2050, energy production will achieve parity with consumption for the first time, striving for “energy independence”;and from 2051 to 2060, aiming for “carbon neutrality”, and establishing an “energy powerhouse”. Building an “energy powerhouse” will fundamentally safeguard national energy security, advance the achievement of carbon neutrality goals, provide Chinese solutions for global energy transition and green Earth construction, and support the modernization and great rejuvenation of the Chinese nation. 展开更多

The understanding of microbial energy acquisition is currently being reshaped.Traditional microbiology has centered on two primary energy acquisition modes:phototrophy,which captures light energy,and chemotrophy,which extracts energy by oxidizing chemical compounds(Fig.1a).While these modes constitute the cornerstone of microbial bioenergetics and the evolution of metabolism,recent discoveries have revealed that microbes can also use alternative energy acquisition strategies that extend beyond this classical dichotomy. 展开更多

The strain energy storage index(WET)is a crucial index for evaluating rockburst proneness.Interestingly,when conducting tests to obtain WET,variations exist in the shape of coal or rock specimens.However,whether shape factors affect WET has not been theoretically and experimentally verified.In this study,to investigate the independence of WET from specimen shape effects,its rationality was first theoretically derived based on the linear energy storage(LES)laws of rock,indicating that WET is influenced by the energy storage coefficient(ESC)of the rock.Two typical rock materials(granite and red sandstone)with different rockburst proneness were selected to verify the migration effect of cubic and cylindrical specimens on WET via uniaxial compression tests.The experimental results revealed that the mechanical behavior characteristics of rocks were affected by the shape of cylindrical and cubic specimens,whereas the WET and ESC were opposite.Furthermore,the practical WET values closely approximate the theoretical values of energy storage-dissipated ratio predicted by the LES law,converging to the peak-strength strain energy storage index(WPET).Based on the LES law,the influence of specimen shape on WET and WPET was further discussed,concluding that WET and WPET are independent of specimen shape effects.Furthermore,the WPET is more stable than WET and reflects the relative magnitude of energy storage and dissipation during the entire pre-peak of rock.Thus,the peak-strength strain energy storage index can be used as a substitute for WET in evaluating the rockburst proneness of rock. 展开更多

In order to address environmental pollution and resource depletion caused by traditional power generation,this paper proposes an adaptive iterative dynamic-balance optimization algorithm that integrates the Improved Dung Beetle Optimizer(IDBO)with VariationalMode Decomposition(VMD).The IDBO-VMD method is designed to enhance the accuracy and efficiency of wind-speed time-series decomposition and to effectively smooth photovoltaic power fluctuations.This study innovatively improves the traditional variational mode decomposition(VMD)algorithm,and significantly improves the accuracy and adaptive ability of signal decomposition by IDBO selfoptimization of key parameters K and a.On this basis,Fourier transform technology is used to define the boundary point between high frequency and low frequency signals,and a targeted energy distribution strategy is proposed:high frequency fluctuations are allocated to supercapacitors to quickly respond to transient power fluctuations;Lowfrequency components are distributed to lead-carbon batteries,optimizing long-term energy storage and scheduling efficiency.This strategy effectively improves the response speed and stability of the energy storage system.The experimental results demonstrate that the IDBO-VMD algorithm markedly outperforms traditional methods in both decomposition accuracy and computational efficiency.Specifically,it effectively reduces the charge–discharge frequency of the battery,prolongs battery life,and optimizes the operating ranges of the state-of-charge(SOC)for both leadcarbon batteries and supercapacitors.In addition,the energy management strategy based on the algorithm not only improves the overall energy utilization efficiency of the system,but also shows excellent performance in the dynamic management and intelligent scheduling of renewable energy generation. 展开更多

Foreword.The rising global energy demand, driven by the extensive use of fossil fuels, has led to growing energy scarcity and environmental challenges, such as global pollution and warming. To address the challenges mentioned above, it is urgent to accelerate the development of renewable energy and promote the transition towards sustainable energy systems.However, the inherent instability of renewables, such as solar and wind power, poses significant challenges to existing grid infrastructures. Energy storage technologies have thus emerged as a promising solution by storing excess electrical energy during off-peak hours for later use. 展开更多

In the context of global decarbonization initiatives and the rapid advancement of electrified railways,the efficient utilization of regenerative braking energy(RBE)has emerged as a critical energy policy in China.RBE not only significantly reduces railway energy consumption but also offers substantial potential for providing auxiliary services to the power grid,enhancing the coordination,economic efficiency,and stability of both railway and power systems.In this paper,we first analyze RBE utilization strategies,including the optimization of train operation scheduling,energy storage technologies,energy sharing mechanisms,and energy feedback configurations.Then,from a macro perspective,the hierarchical structure of the RBE control system is explored.The upper-level energy management system of regenerative braking exhibits development trends based mainly on thresholds,optimization,and learning.Meanwhile,the lower-level converter control system tends to adopt strategies that improve the voltage balance and circulating current performance of the modular multilevel converter-railway power conditioner(MMC-RPC)while reducing the computational burden.Finally,based on existing theoretical research and practical engineering applications,rational suggestions are proposed to enhance the utilization efficiency of RBE.These recommendations provide strong support for the efficient utilization of RBE in alternating-current electrified railways(ACERs),as well as for technological innovation and economic development. 展开更多

This study investigates the problem of prioritizing rooftop renewable energy(RE)system configurations for a multi-family residential building in Mediterranean climate.The analysis focuses on fixed-tilt photovoltaics(PV),single-axis and dual-axis tracking PV,and small vertical-axis wind turbines(VAWT),each assessed with and without lithium-ion storage.A co-simulation framework is used,coupling EnergyPlus building-HVAC system simulation with PV and wind generation modeling and rule-based battery dispatch to evaluate hourly demand–supply interactions.Three decision criteria are considered for each alternative:total system cost,annual building electric energy demand reduction,and net avoided life-cycle emissions.Stakeholder preferences are elicited via Analytic Hierarchy Process(AHP),considering the building owner as the decision-maker.The design alternatives are then ranked with three multicriteria decision-making(MCDM)methods(TOPSIS,ARAS,and COPRAS)and a global rank is computed through an ensemble(Borda)aggregation.Results show that due to roof-area constraints,dense fixed-tilt PV system layouts are favored to achieve maximum annual generation(≈60.8 MWh per year),whereas tracking systems achieve higher specific yield but lower system capacity per roof because of increased need of spacing and maintenance corridors.Design alternatives that incorporate energy storage significantly raise self-consumption and demand reduction.Indeed,fixed PV with large storage can reach high annual coverage of building electric energy consumption,while the same PV without storage can reduce it by~43.7%.VAWT options contribute modestly to energy demand reduction given unfavorable urban wind conditions and their shorter lifetime.Under owner-centric weights that emphasize cost,the ensemble ranking prioritizes low-CAPEX PV solutions(dual-axis PV without storage,single-axis PV without storage,single-axis PV with small storage,and fixed-tilt PV).Instead,design alternatives encompassing large energy storage and small-wind alternatives occupy the lower ranks.The findings provide useful insights and a stakeholder-wise tool to select rooftop RE technologies on Mediterranean residential buildings,balancing economic feasibility with energy and environmental performance. 展开更多

With the deep integration of energy and information networks,the low-carbon,efficient,and economical oper-ation and management of integrated energy systems are increasingly driven by digital twins and large artificial intelligence models,which rely heavily on the robust support of the Internet of Things and big data.However,the data interaction process within energy systems faces issues such as varying privacy protection demands and conflicts of interest among participating entities,leading to development bottlenecks like prominent data silos,a lack of secure sharing mechanisms,and low collaborative efficiency.As a novel infrastructure for data resource circulation,the energy data space integrates various software and hardware encryption methods to construct a trusted execution environment,providing solutions for the secure sharing and value realization of energy data re-sources.Based on a decentralized yet adjustable underlying architecture,the energy data space can be adaptively designed according to the coupling characteristics of energy and information flows,meeting the real-time,effi-ciency,and scalability requirements of cross-entity systems and large-scale businesses.This paper investigates,analyzes,and summarizes technical routes through which the energy data space can facilitate the digital and intelligent transformation of integrated energy systems.It also elaborates on the supporting role of the energy data space in the conceptual architecture,technical support,application scenarios,and value creation of energy industry upgrading. 展开更多

To investigate the energy relief effect of real-time drilling in preventing rockburst in high-stress rock,a series of high-stress real-time drilling uniaxial compression tests were conducted on red sandstone specimens using the SG4500 drilling rig.Results showed that the mechanical behavior(i.e.peak strength and rockburst intensity)of the rock was weakened under high-stress real-time drilling and exhibited a downward trend as the drilling diameter increased.The real-time drilling energy dissipation index(ERD)was proposed to characterize the energy relief during high-stress real-time drilling.The ERD exhibited a linear increase with the real-time drilling diameter.Furthermore,the elastic strain energy of post-drilling rock showed a linear relationship with the square of stress across different stress levels,which also applied to the peak elastic strain energy and the square of peak stress.This findingreveals the intrinsic link between the weakening effect of peak elastic strain energy and peak strength due to high-stress real-time drilling,confirmingthe consistency between energy relief and pressure relief effects.By establishing relationships among rockburst proneness,peak elastic strain energy,and peak strength,it was demonstrated that high-stress real-time drilling reduces rockburst proneness through energy dissipation.Specifically,both peak elastic strain energy and rockburst proneness decreased with larger drill bit diameters,consistent with reductions in peak strength,rockburst intensity,and fractal dimensions of high-stress real-time drilled rock.These results validate the energy relief mechanism of real-time drilling in mitigating rockburst risks. 展开更多

Shared energy storage helps lower user investment costs and enhances energy efficiency,which is considered a pivotal driver in accelerating the green transition of energy sectors.In view of the increasing demand for hydrogen,this paper proposes a bi-level optimization of configurations and scheduling for combined cooling,heating,and power(CCHP)microgrid systems considering shared hybrid electric-hydrogen energy storage service.The upper-level model addresses the capacity allocation problem of energy storage stations,while the lower-level model optimizes the operational strategies for the multi-microgrid system(MMS).To resolve the complexity of the coupled bi-level problem,Karush-Kuhn-Tucker(KKT)conditions and the Big-M method are applied to reformulate it into a solvable mixed-integer linear programming(MILP)model,compatible with CPLEX.The economic viability and rationality of the proposed approach are verified through comparisons of three cases.Numerical results show that the proposed approach reduces user annual costs by 20.15%compared to MMS without additional energy storage equipment and achieves 100%renewable absorption.For operators,it yields 5.71 M CNY annual profit with 3.02-year payback.Compared to MMS with electricity sharing,it further cuts user costs by 3.84%,boosts operator profit by 60.71%,and shortens payback by 15.88%. 展开更多

The global energy landscape has undergone a dramatic transformation since 2021,with solar photovoltaic(PV)technology emerging as the cornerstone of decarbonization efforts.This study provides a comprehensive and forward-looking analysis of solar deployment trends,cost dynamics,and the integration of energy storage as a resilience enabler in smart energy systems.This work offers a comprehensive synthesis of multi-dimensional drivers—technological innovation,policy frameworks,and market dynamics—and quantifies their combined impact on cost competitiveness and grid stability,advancing beyond the scope of previous studies that often treat these factors in isolation.We highlight the unprecedented convergence of ultra-low levelized cost of electricity(LCOE),hybrid solar-plus-storage adoption,and digital grid solutions,supported by recent data from IRENA,Lazard,and BloombergNEF.Furthermore,we introduce a conceptual framework linking storage deployment to grid flexibility and resilience,offering actionable insights for policymakers and industry stakeholders.By integrating technical,economic,and policy perspectives,this paper advances the discourse on achieving net-zero targets and positions solar energy as the backbone of a resilient,equitable,and digitally optimized energy future. 展开更多

Several countries all over the world are interested in the energy business.The scientific community is creating new energy-saving experiments in response to the present fossil fuel problems.Buildings are one of the components that use more energy,so it is highly desirable that knowledge is being generated and technology is developing to provide answers to this energy demand.When used in building elements for heating and cooling like coatings,blocks,panels or wall panels,phase change materials(PCMs)have been demonstrated to enhance the capacity for heat storage by absorbing heat as latent heat.Thus,during the past 20 years,research has been done on the application of phase change materials(PCMs)in latent heat storage systems.The most practical way to incorporate PCMs into construction parts is through the macro encapsulation approach,which is examined in this review together with the microencapsulation method.Furthermore,given that additional research is required to process biobased PCMs,we must pay greater attention to them,as evidenced by our examination of the literature on the encapsulation process of PCMs.Due to the lack of information provided in other reviews,there is a section dedicated to the superior PCM with lightweight material to ascertain its macro and microscale thermophysical and mechanical characteristics as well as to determine whether it would be feasible to switch from PCM that are made from petroleum to more ecologically friendly bio-based ones.Above all,this study also focuses on reviewing recent PCM research and evaluating the thermal performance of prototypes used in experimental PCM investigations,i.e.,how the layout of design affects several variables and potential applications of PCM. 展开更多

This paper evaluates the role of aggregated demand-side flexibility from public buildings in supporting renewable energy integration and decarbonization of the Slovenian energy system.Using high-resolution monitoring data from over 100 public buildings and the H2RES energy system optimization model,two long-term scenarios are analyzed for the period 2020-2050:a reference scenario without public building flexibility and a flexibility scenario in which public building heat demand is electrified via heat pumps.The year 2020 is used as an internally consistent optimization reference for demand levels and technology availability,rather than as a statistical reconstruction of the observed national energy system.Reported CO2emissions represent modelled energy-system emissions within the covered sectors(power,heat,and industry)under exogenously imposed policy constraints and therefore may differ fromnational inventory totals.The results showthat aggregated public building flexibility affects the temporal allocation of electricity demand and sectoral emission distribution,leading to moderate changes in renewable curtailment and heat-sector CO2emissions while maintaining identical renewable energy targets.The findings demonstrate that electrification and aggregation of public building demand can play a strategic role in supporting national climate objectives and system operation under high renewable penetration.It should be noted that the analyzed dataset,while based on high-resolution monitoring of more than 100 public buildings,is not statistically scaled to represent the full national building stock.The results should therefore be interpreted as indicative of system-level effects of aggregated flexibility rather than a direct national-scale quantification. 展开更多

The present research focuses on passive and active concepts applied to a house located in a remote area of the Ghardaïa region.Passive architectural concepts refer to a set of design approaches that focus on using the natural environment instead of purchased energy such as electricity or natural gas to provide heating,cooling,ventilation and lighting to a building.On the other hand,active design strategies use purchased energy to maintain the comfort in the building.The aim is to reduce the energy requirements for heating and air conditioning so as to make this habitat more energy efficient.On the other hand,the cost-effectiveness of photovoltaic installations is frequently questioned in these climatic regions,resulting in a significant initial investment,hence the main objective.As a result,it was deduced that passive architectural concepts have priority over active ones from an energy and financial point of view.The sun is not the only parameter to be taken into consideration when testing the profitability of stand-alone photovoltaic systems in Algeria,whatever the energy class of the residential premises.The lifespan of batteries and the very low price of conventional electricity are major obstacles to developing this technology.Subsidies and financial aid for these actions can be an alternative to subsidizing conventional electricity at a high rate,sometimes in excess of 60%.This approach can eventually make photovoltaic systems profitable,and systematically rationalize the use of the country’s exhaustible,non-renewable natural resources.For nominal voltages of 48 V,it makes more sense to avoid a costly electrical storage system,instead deploying a hybrid inverter that intelligently manages electricity consumption and determines whether it’s best to use the electricity generated immediately or to feed it into the grid. 展开更多
