The urgent need for CO2 reduction is calling upon the industry to contribute. However, changes within local energy supply systems including efficiency enhancement are bound several economical and technical constraints, which results in interfering trade-offs that make it difficult find optimal investment option mitigation. In this article, a new optimization model presented allows optimize design operation of heat recovery system production scheduling simultaneously. was used retrofitting...
Steel production is one of the biggest emitters greenhouse gas in industrial sector with about 8% total global CO2 emissions. Although majority emissions can be attributed to primary steel production, there also potential for reducing downstream processing. Large furnaces, which are necessary heating steel, currently primarily fired natural and by-product gases from offering great heat recovery measures exhaust gases. However, switching alternative climate-neutral fuels could change this...
In this paper the results of a numerical investigation melting and solidification process sodium nitrate, which is used as phase change material, will be presented. For heat transfer to nitrate different finned tube designs, namely helical-, transversal- longitudinal tubes, are used. The for design cases compared. analysis has shown that apart from first period charging natural convection dominant mechanism. also fast exchanger tubes should designed in such way an unrestricted guaranteed....
The melting and solidification process of sodium nitrate, which is used as energy storage material, studied in a vertical arranged device with two different bimetal finned tube designs (with without additional lateral fins) for enhancing the heat transfer.The design consists plain steel while material longitudinal (axial) fins aluminum.The investigation analyses influence on charging discharging process.Three-dimensional transient numerical simulations are performed using ANSYS Fluent 14.5...
Predicting the outcome of possible changes in interlinked industrial energy systems is hard, especially retrofit scenarios. This leads to severe uncertainties when making investment decisions. In this paper, a new combined optimization approach presented that aims support decision-making these cases. Our links models for optimal design supply and heat recovery with operational constraints specifically designed applications. It formulated as single mixed-integer linear programming (MILP)...
Due to increased share of fluctuating renewable energy sources in future decarbonized, electricity-driven systems, participating the electricity markets yields potential for industry reduce its costs and emissions. A key enabling technology is thermal storage combined with power-to-heat technologies, allowing industries shift their demands periods low prices. This paper presents an optimization-based method which helps select dimension cost-optimal a given industrial steam process. The...

The production of silicon is an energy-intensive process, which requires high temperatures. Sudden release high-temperature gas to the exhaust system inevitable part furnace operation and causes strong fluctuations in waste heat recovery system. This makes challenging leads frequent throttling produced steam reducing efficiency To avoid this thus increase efficiency, retrofitting a thermal energy storage existing analyzed for plant Norway. A accumulator installed parallel bypasses, does not...
In this study, we employ an optimization model to optimally design a self-sufficient, independent of any imports and exports, hydrogen infrastructure for Austria by 2030. Our approach integrates key technologies within detailed spatial investment operation – coupled with European scale electricity market model. We focus on optimizing diverse components including trailers, pipelines, electrolyzers, storages meet Austria's projected demand. To accurately estimate demand in hourly resolution,...
In the pharmaceutical industry, energy efficiency has played a minor role compared to other energy-intensive industries. However, there is growing recognition of need address environmental concerns. With ambitious climate targets and increasing demand for significant reductions in CO2 emissions, industry now embracing opportunity enhance its sustainability practices. Mainly fossil fuels are used provide process steam at moderate temperature levels about 160-180°C lesser extent hot water or...
An increasing population with the need of new buildings in combination global warming is important issues ahead.Hence, for defining a clear path towards low and zero-emission building stock EU by 2050, as recently stated EPBD recast, Nearly Zero Energy Buildings are one many necessary measures climate change mitigation.Finding cost optimal solutions important, where short time perspective narrow concept evaluation may be wrong.This study presents Net Building Sweden, verified plus energy...
