Summary: The successful use of process modeling and simulation in fast pyrolysis plants has become essential in their design and operation. This study proposes an expanded pyrolysis simulation model for lignocellulosic biomass, which predicts the yield for both slow and fast pyrolysis processes and shows a significant correlation with experimental results. The simulation model is proven to be reliable in predicting pyrolysis yields and product composition.

Summary: Indoor farming, which involves growing crops on vertically stacked layers in a soilless system, offers improved productivity, water use efficiency, and reduction in food miles compared to conventional open-field farms. However, indoor farming facilities require a significant amount of energy to maintain ideal growing conditions. This study evaluated the energy performance of indoor farming operations through measurements and simulations. Energy models were created to assess the effectiveness of energy-saving strategies in improving efficiency. The findings highlight the potential for substantial reduction in energy consumption through the implementation of these strategies.

Summary: We propose a new forward electricity market framework that allows for heterogeneous market participants to express their nonlinearities in costs and constraints through conic bids. This framework also includes a network operator with operational constraints. The inclusion of second-order cone constraints improves the market's awareness of uncertainty, assets, and networks, enabling a successful transition to weather-dependent renewable energy sources.

Summary: Driven by the demand for intermittent power generation, Energy Storage (ES) will be widely adopted in future electricity grids to provide flexibility and resilience. However, existing models are inadequate to address grids with a high percentage of renewables and ES, and there is a challenge in integrating short-term temporal changes in LEPSMs due to model complexity and computational cost. Therefore, there is a need for a novel long-term electrical power system modeling framework that can effectively incorporate ES and low-carbon power generation.

Summary: With the increasing penetration of distributed energy resources (DERs), more consumers capable of producing energy (prosumers) are appearing in the electricity distribution network. To facilitate the active participation of prosumers in the market, a continuous group-wise double auction (CGDA) mechanism has been developed to coordinate energy transactions among prosumers.

Summary: This article explores a two-stage market mechanism for electricity trading with renewable energy, as an alternative to the commonly used multisettlement market structure. The model allows for recourse decisions by the market operator, considers different generation costs in different stages, and incorporates demand response and network constraints. It demonstrates the existence of a sequential competitive equilibrium in such a market, and designs a market mechanism to maximize social welfare when participants are non-strategic. It also shows the existence of an efficient Nash equilibrium under specific conditions.

Summary: This paper examines the impact of real-time pricing and load automation on residential distribution systems. The study finds that implementing real-time pricing can result in an aggregate welfare gain of 39 USD per customer and year. However, it also notes that RTP and load automation may significantly increase peak system load. Introducing a market-based demand management system can further enhance welfare gains and reduce grid investment.

Summary: Household solid fuel use is detrimental to health and the environment. The Indian government's PMUY subsidy has successfully promoted the adoption of LPG by millions of households. However, there is limited understanding of the decision-making process to reduce solid fuel use after transitioning to cleaner fuels. This study found that factors such as household wealth, social status, education level, and the prevalence of LPG use in the village are positively associated with LPG consumption and the discontinuation of solid fuel use. On the other hand, factors such as distance to LPG refill delivery, household size, and the PMUY subsidy are negatively associated with the share of LPG use.

Summary: This paper assesses the performance of differently implemented forward-looking network tariff designs and proposes an innovative coordination mechanism to increase predictability in a future with many flexible customers. The study reveals that if large shares of customers synchronize their responses to highly time-varying and locational-specific network charges, it can lead to unexpected reinforcements.

Summary: Russia's weaponization of gas supplies shook the energy security of Central and Eastern Europe in 2022. The region responded by increasing alternative energy supplies and developing new gas supply routes. Renewable energy, nuclear energy, and hydrogen play important roles in the long-term. Mitigating the impact of this shock requires the EU to prioritize the integrity of its energy market.

Summary: Economic costs are a major political obstacle to investing in climate change mitigation and adaptation measures. The method of financing plays a crucial role in determining public opposition to government green investments, with debt financing being less opposed than broad-based taxes. This study suggests that credit market tools, such as green bonds and debt for climate swaps, can be politically efficient in increasing support for green financing. Carbon taxes and wealth taxes are found to be the most preferred options.

Summary: This paper investigates China's energy trade stability using a survival analysis approach. It finds that the energy trade linkages between China and 153 other countries are complex and unstable, with short periods of trade with many countries. Geopolitically risky regions, such as the Middle East and Africa, have the lowest trade stability. Climate risks have significant effects on energy trade stability. The paper proposes several policy options to improve energy trade stability in China, with special attention to increasing global climate risks.

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: The study finds that oil price shocks have a negative impact on Africa's energy transition, particularly in rural areas and net crude oil exporting countries. However, oil price shocks cannot explain the urban-rural differences in clean energy access. Therefore, increasing investment in clean energy and technologies in rural areas is necessary to enhance the resilience of the energy sector to oil price shocks.

Summary: The Renewable Energy Certificate (REC) is considered an innovative technology for building a green society. This study investigates the impact of REC purchases on stock return and volume in Taiwan between 2017 and 2021. The findings suggest that REC purchases have a positive effect on stock returns of manufacturing firms but not service firms. The frequency of REC purchases is also an important factor in the relationship between REC purchase and firm value. Additionally, the study reveals that public attention to environmental pollution plays a crucial role in positive stock returns and volume, while ESG disclosure is negatively associated with returns and volume.

Summary: This paper addresses the challenges of governing energy procurement from a mix of non-hydropower renewable energy sources supplied by independent producers. Building on political economy analysis and five case studies of independent producer projects from Ethiopia, it seeks to understand the root causes of the protracted delays and limited extent of procurement by independent producers. The key contestations lie in managing long term contracts, risk, uncertainty and in developing the institutional and human capacity to transition.
