“…Figure 6 shows the impacts of economic factors on MJSP. As in previous studies, 62,65,66 feedstock cost was the most significant parameter controlling the price of the product, followed by the catalyst life, the co-product selling price, and the catalyst cost. Increasing the cost of the feedstock from $0.1/kg to $0.3/kg resulted in a 30% increase in MJSP.…”

In this study, process simulation and techno‐economic analysis (TEA) were conducted to evaluate the production of renewable jet fuel (RJF) through the pyrolysis‐to‐RJF process. The process model was developed based on experimental results for the renewable jet fuel production process using the fast pyrolysis of rice husk, hydro‐processing of pyrolytic oil, and hydro‐cracking / isomerization of hydro‐processed oil. The mass and energy flows were input into the TEA model, which was established based on local conditions in Taiwan. The study included three parts: (1) the mass, energy and carbon balances – the major product, RJF, gave an energy yield of 26.8%, a mass yield of 9%, and a carbon yield of 21%; (2) an economic analysis – the MJSP of RJF for the pyrolysis‐to‐RJF process was $3.21/L, based on the plant capacity of 600 tonnes per day; (3) a sensitivity analysis: the impacts of the feedstock cost, catalyst life, co‐product selling price, catalyst cost, hydrogen cost, and plant capacity were discussed. This study demonstrated the economic potential of locally developing a pyrolysis‐to‐RJF process to produce RJF from solid biomass. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd

“…Kangas et al [27] defined a steady state simulation model of a kraft pulp mill and evaluated the economic feasibility of the process. In the field of biorefineries, steady state simulation has been used for process modelling and evaluating the economic performance of biomethane [28], bioethanol [29], biodiesel [30], and renewable diesel production [31]. Barbosa et al [32] used steady state simulation to study carbon capture and utilization opportunities in a sugarcane biorefinery.…”

Towards Semi-Automatic Generation of a Steady State Digital Twin of a Brownfield Process Plant

Researchers have proposed various models for assessing design alternatives for process plant retrofits. Due to the considerable engineering effort involved, no such models exist for the great majority of brownfield process plants, which have been in operation for years or decades. This article proposes a semi-automatic methodology for generating a digital twin of a brownfield plant. The methodology consists of: (1) extracting information from piping and instrumentation diagrams, (2) converting the information to a graph format, (3) applying graph algorithms to preprocess the graph, (4) generating a simulation model from the graph, (5) performing manual expert editing of the generated model, (6) configuring the calculations done by simulation model elements and (7) parameterizing the simulation model according to recent process measurements in order to obtain a digital twin. Since previous work exists for steps (1–2), this article focuses on defining the methodology for (3–5) and demonstrating it on a laboratory process. A discussion is provided for (6–7). The result of the case study was that only few manual edits needed to be made to the automatically generated simulation model. The paper is concluded with an assessment of open issues and topics of further research for this 7-step methodology.

“…In recent decades, the strategy of maintaining a single energy supply pattern has been developed into a comprehensive strategy with multiple strategic goals and interactions [30]. Current economic policies and technology applied in Korea [31], Malaysia [32], Ghana [33] and China [34] were investigated. Usually, the investment cost of the transition from the traditional energy-dependent strategy to a renewable one should be carefully evaluated, and the economic feasibility is highly determined by raw materials, output quantity and output price [35].…”

The global COVID-19 pandemic has had strong impacts on national and international freight, construction and tourism industry, supply chains, and has resulted in a rapid decline in the demand for traditional energy sources. In fact, research has outlined that urban areas depend on global supply chains for their day-to-day basic functions, including energy supplies, food and safe access to potable water. The disruption of global supply chains can leave many urban areas in a very vulnerable position, in which their citizens may struggle to obtain their basic supplies, as the COVID-19 crisis has recently shown. Therefore, solutions aiming to enhance local food, water and energy production systems, even in urban environments, have to be pursued. The COVID-19 crisis has also highlighted in the scientific community the problem of people’s exposure to outdoor and indoor pollution, confirmed as a key element for the increase both in the transmission and severity of the contagion, on top of involving health risks on their own. In this context, most nations are going to adopt new preferential policies to stimulate the development of relevant sustainable energy industries, based on the electrification of the systems supplied by renewable energy sources as confirmed by the International Energy Agency (IEA). Thus, while there is ongoing research focusing on a COVID 19 vaccine, there is also a need for researchers to work cooperatively on novel strategies for world economic recovery incorporating renewable energy policy, technology and management. In this framework, the Sustainable Development of Energy, Water and Environment Systems (SDEWES) conference provides a good platform for researchers and other experts to exchange their academic thoughts, promoting the development and improvements on the renewable energy technologies as well as their role in systems and in the transition towards sustainable energy systems. The 14th SDEWES Conference was held in Dubrovnik, Croatia. It brought together around 570 researchers from 55 countries in the field of sustainable development. The present Special Issue of Energies, specifically dedicated to the 14th SDEWES Conference, focuses on four main fields: energy policy for sustainable development, biomass energy application, building energy saving, and power plant and electric systems.
