Summary: This study estimates the willingness to pay of Indian urban consumers for a continuous supply of electricity using contingent valuation method. The findings show that the amount consumers are willing to pay depends on the duration of power outages, with households preferring shorter outages. Income and environmental attitude also positively influence higher willingness to pay. These insights can inform policymakers in designing more reliable and customer-centric energy generation and distribution models.

Summary: This paper analyzes the economic potential of Power-to-Gas (PtG) as a source of flexibility in electricity markets, highlighting its ability to reduce electricity price volatility. However, the impact of PtG on price volatility diminishes in scenarios with high external demand for hydrogen. Despite the positive welfare effects in certain cases, challenges remain due to fixed costs and the costs of replacing a cheaper energy carrier with a more expensive one.

Summary: The construction sector plays a crucial role in energy consumption and greenhouse gas emissions. Promoting green buildings could be an effective solution to tackle environmental issues. This study conducted a choice experiment to investigate preferences and willingness to pay for different attributes of green office buildings in Shanghai. The findings indicate that respondents highly value attributes related to indoor comfort and health, as well as power saving and water saving features. People working in higher rental offices are more likely to pay for air purifier installation. Construction and manufacturing firms show higher willingness to pay for power saving and lower willingness to pay for soundproofing. Overall, foreign firms are willing to pay more for eco-friendly materials.

Summary: This paper proposes a stochastic decision-making strategy for the optimal short-term management of a power-to-gas included energy hub in natural gas and electricity markets. The model uses cross-product arbitrage and risk measurement to submit optimal bids, considering price uncertainties. By solving the mixed-integer linear programming problem, the simulation results demonstrate the benefits of implementing power-to-gas equipment and exploiting cross-product arbitrage in terms of decision-making capability and cost savings in energy procurement.

Summary: The compensation for the opportunity costs of capital through the Weighted Average Costs of Capital (WACC) is crucial in the regulation of network tariffs. However, determining the appropriate level for the WACC is problematic due to uncertainty in future conditions of capital markets. By considering uncertainty and trading off consumer surplus and expected disruption costs, it is concluded that in most cases, the optimal WACC for tariff regulation is above the historical mean costs of capital. Only in situations of high uncertainty and quick increase in investment levels, the optimal WACC can be below the historical mean.

Summary: This paper analyzes the most competitive sources of low-carbon hydrogen for the Northwest European market, considering local production, conversion, and transport costs. The production costs of electrolysis are strongly influenced by local renewable electricity costs and capacity factors. For distances under 10,000 km, the lowest transport costs are achieved through pipelines, with costs increasing linearly with distance. For longer distances, ammonia transport is more efficient, despite higher conversion costs. The most competitive sources of low-carbon hydrogen for the Northwest European market are Steam Methane Reforming with Carbon Capture and Storage when international gas prices return to historical levels, and import from Morocco with electrolysis directly connected to offshore wind generation when gas prices remain high.

Summary: This study examines the profitability of producing green hydrogen through electrolyzers in alleviating congestion in medium-voltage distribution grids with high amounts of renewable energy sources. An incentive-based method for improving flexibility in these grids is proposed, and the results show that converting power to hydrogen can be an economically efficient way to reduce congestion when there is a high amount of renewable energy. However, the economic value of electrolyzers as flexibility providers decreases when more options for flexibility provision exist.

Summary: The chemical industry needs to reduce its carbon emissions, and this study examines the economic feasibility of different abatement technologies. The Marginal Abatement Cost (MAC) of CO2 emissions for 24 firms in the European chemical sector from 2015-2020 is estimated using a quadratic directional output distance function (DDF) model. The findings suggest that most firms prefer carbon allowances instead of reducing their own emissions, unless the carbon price significantly increases or financial support is provided for specific abatement technologies such as renewable hydrogen and bio-based ammonia.

Summary: Electrochemical water splitting is crucial for hydrogen production, and improving the hydrogen separation rate from the electrode is essential for enhancing water electrolyzer performance. However, issues such as air bubble adhesion to the electrode plate hinder the process. Therefore, a methodology to investigate the two-phase flow within the electrolyzer is in high demand. This study proposes using a microfluidic system as a simulator for the electrolyzer and optimizing the two-phase flow by manipulating the micro-structure of the flow.

This study proposes a novel day-ahead scheduling model that considers the flexibility limited by irregular vibration zones (VZs) and the probability of flexibility shortage in a hydropower-variable renewable energy hybrid generation system. The model is applied to a real hydropower station and effectively improves the flexibility supply capacity of hydropower, especially during heavy load demand in flood season.
