Summary: Achieving high or ultrahigh carbon-free or renewable energy mixes requires combining multiple flexibility options, including renewable curtailment, short-duration, long-duration, and seasonal storage. The cost competitiveness of seasonal storage becomes crucial between 80% and 95% energy mix targets, depending on the specific power system. Additionally, using storage-to-storage operation and decoupling of charging and discharging storage power capacity are cost-effective options for integrating high shares of carbon-free or renewable power sources.

Summary: Increasing the share of renewable energy in the global energy system requires more flexibility, with customer-sited energy storage systems being a promising measure. A case study in Sichuan Province, China, showed that customer-sited energy storage can partially replace coal power plants, reduce CO2 emissions, but currently cannot generate profits. Further reduction in storage costs, improved technology, and policy support are needed to enhance the development of customer-sited energy storage systems.

Summary: The increase in renewable energy production, particularly from wind, has led to grid variability, necessitating the use of clean, reliable back-up electricity generation. Although nuclear power is a clean and reliable option, it lacks the flexibility to compensate for uncertainties in renewable energy production. Therefore, appropriately sized energy storage solutions are needed to maintain grid stability while utilizing both renewable and nuclear energy sources.

Summary: The uncertainty of wind power output increases the probability of supply-demand imbalance and weakens the frequency response capability of the power system. A risk assessment method considering the governor ramp rate of conventional units is proposed to address the lack of attention to response speed in previous studies. The method includes a comprehensive risk index and an optimal power flow model to quantify the consequences of stochastic system states.

Summary: With the increasing penetration of variable renewable energy (VRE) like wind power, it is challenging to ensure the flexible and secure operation of the power system solely relying on conventional sources. This research proposes a robust energy and reserve dispatch method that considers the flexibility of wind power. It establishes a model to measure the output and reserve margin of wind power under uncertain scenarios and links the reserve capacity of wind farms between base and uncertain scenarios, ensuring deliverability of wind power reserve even in uncertain situations.

Summary: This paper discusses the importance of blackstart capability for wind turbines to recover power systems from blackouts and proposes a grid-forming controller for Type 4 wind turbines to enhance their ability to restore power. It also introduces an active protection system to prevent turbine stalling during recovery. Simulation results demonstrate that Type 4 wind turbines with the developed controllers and protection subsystem can successfully re-energize a wind-dominant grid, withstand asymmetrical faults, and survive low-wind-speed events.

Summary: Western Denmark is an independent bidding area in the Nord Pool power market, where wind power contributes over 50% to the annual production. We analyze hourly market data from the Danish Transmission System Operator (TSO) for the period of 2009-2021. Prior to the energy crisis in 2021, the Nordic power market has shown relatively stable prices, while extreme events have only moderately increased. The value factor of wind power remains stable, indicating that the current infrastructure and market organization can effectively handle the installed wind power capacity.

Summary: There is controversy regarding the mechanisms behind the changes in brain shape during the evolution of modern humans. Recent studies suggest that high levels of covariation between brain cortical areas in modern humans and Neanderthals evolved under distinctly higher evolutionary rates than in any other primate, indicating that the highly integrated brain played a critical role in the evolution of unique cognitive capacities and complex behaviors.

Summary: Low-carbon energy transitions worldwide are driven by integrating renewable energy sources like wind and solar power, requiring energy storage options. This article proposes using decommissioned underground mines as storage reservoirs and a gravitational-based energy storage method called Underground Gravity Energy Storage (UGES). UGES can discharge electricity by lowering sand into the mine and store electricity by elevating sand from the mine. Unlike battery storage, UGES has zero self-discharge rate and uses sand as the storage medium, reducing the risk of contaminating underground water resources. It offers weekly to pluriannual energy storage cycles with investment costs of 1 to 10 USD/kWh and a global energy storage potential of 7 to 70 TWh, supporting sustainable development through seasonal energy storage services.

Summary: Technology-rich integrated assessment models (IAMs) provide high resolution of the energy-related climate impacts but usually ignore industrial linkages and other environmental pressures. This manuscript presents a method for coupling energy system models (ESMs) with multiregional input-output models (MRIOs) based on the Make and Use framework, which improves both models simultaneously. An exemplary case study is carried out to illustrate the usefulness and challenges of this approach, and further steps are identified for systematic prospective analyzes.

Summary: To comprehensively analyze and achieve climate mitigation goals, factors of justice and fairness as well as new carbon dioxide removal technologies should be considered. Introducing novel carbon dioxide removal technologies, including direct air capture of CO2 and institutional capacity, can enhance the feasibility and fairness of mitigation scenarios. However, relying solely on carbon removal measures in developed countries is not sufficient to achieve the 1.5℃ target of the Paris Agreement, and further technical and financial transfers are needed for equitable achievement.

Summary: The Finnish Government's target of carbon neutrality by 2035 poses a challenge for the district heat systems of Finnish cities, which still heavily rely on fossil fuels and peat. To address rising heat prices and prevent energy poverty, affordable low-carbon district heat solutions need to be developed. This study investigates the feasibility of various low-carbon scenarios utilizing biomass combustion and waste heat recovery technologies in different energy renovation levels. Economic and sensitivity analyses were conducted from utility and end-user perspectives, highlighting biomass HOB and waste heat-heat pump + electric boiler as cost-effective options.
