Summary: This study integrates energy storage and low-carbon technologies under stability requirements and different climate conditions to analyze their role in decarbonizing the power system. The results show that batteries and hydrogen fuel cells have low penetration and negligible emission reduction. Compressed air storage has limited effectiveness in the short term but improves in the long term. Flexible generation technologies based on hydrogen turbines and long-duration storage provide the greatest decarbonization potential, covering 11-14% of demand in the short and long term. Decarbonizing the electricity system and achieving Paris targets is possible without significant cost increase.

Summary: Increasing renewable power generation is a way to reduce carbon emissions in the power system. Hydrogen can be used as an energy vector in a Power-to-Power system to optimize the energy flow from renewables to users. The proposed Renewable Energy Community (REC) aims to involve users in energy management and promote local renewable energy development. The PtP hydrogen-based system introduced in this work, with the integration of RECs, significantly enhances users' self-sufficiency despite its economic unsustainability.

Summary: Spain has proposed a plan to reduce conventional energy sources and increase the use of renewable energy, resulting in a surplus of electrical energy in spring and summer but a deficit in autumn and winter. By deploying electrolysers to produce hydrogen from surplus energy and blending it with natural gas for use in turbines, up to 7.27 TWh of surplus renewable energy can be reused annually, avoiding 2.54 million tons of CO2 equivalent emissions.

Summary: This study analyzed decarbonization pathways for space heat and hot water to meet ambitious EU climate targets using the Balmorel framework. The most cost-effective solution was found to be electrification, requiring substantial investment in wind energy infrastructure. Seasonal variation in heat demand poses challenges, leading to extreme high and low prices and substantial curtailment in summer.

Summary: This paper presents a new optimization approach for hybrid heating systems that combine centralized district heating assets and decentralized heat pumps. A modeling tool was developed to assess the impact of adding heat pumps to the existing district heating system. The results show that optimal use of heating assets can significantly reduce operating expenditure. To fully realize the benefits, heat pumps should be utilized to provide ancillary services and receive compensation for feeding heat into the district heating network. Sensitivity analysis was conducted to evaluate the robustness of the modeling results.

Summary: This study investigates the deployment of supply side flexibility options in the future European power system. Different scenarios are explored, and it is found that additional flexibility options are needed for moderate decarbonization levels with high shares of variable renewable energies (VRE). The deployment of power storages grows nonlinearly as the system approaches a zero-emission system, mainly driven by hydrogen storage investments.

Summary: This paper develops a consistent thermodynamic and economic methodology to assess the competitiveness of different options for transitioning away from natural gas in domestic heating. The study compares electrification, hydrogen substitution, and district heating, and shows that electrification with electric heat pumps is the least-cost decarbonisation pathway. However, if hydrogen is produced cost-effectively by methane reforming and carbon capture and storage, the total system cost associated with hydrogen technologies becomes more competitive.

Summary: Fuel cell electric vehicles offer a viable option to utilize surplus energy from renewables and reduce environmental impacts in the transport sector. However, the environmental performance of certain components, like hydrogen storage tanks made of carbon composite materials, remains uncertain. Ongoing studies suggest potential improvements in the environmental performance of the tanks, especially in terms of climate change and human toxicity.

Summary: To achieve the CO2 reduction targets for 2050, extensive measures are needed in all sectors, particularly in transportation which has not yet seen substantial reduction in emissions. Increasing the use of electric vehicles powered by batteries or fuel cells and utilizing synthetic fuels made from hydrogen and carbon dioxide are key strategies. These options require significant expansion of renewable electricity generation capacities. Analyzing various road freight transport options can help improve efficiency and address the challenges in fulfilling long-distance transport requirements.
