“…There is also potential in adding hydrogen into existing gas pipelines, where it is estimated that at least 2% by volume of hydrogen can be added without specific technical modifications [3], which means around 250,000 tonnes of H 2 for Europe [9]. This raises the question of hydrogen's competitiveness compared to other energy sources, as at hydrogen's production price, e.g., 6 €/kg H 2 , the price of energy (120 €/MWh) is significantly higher than the price of energy obtained from natural gas (34 €/MWh) [6].…”

This paper discusses the potential of green hydrogen production in a case study of a Slovenian hydro power plant. To assess the feasibility and eligibility of hydrogen production at the power plant, we present an overview of current hydrogen prices and the costs of the power-to-gas system for green hydrogen production. After defining the production cost for hydrogen at the case study hydro power plant, we elaborate on the profitability of hydrogen production over electricity. As hydrogen can be used as a sustainable energy vector in industry, heating, mobility, and the electro energetic sectors, we discuss the current competitiveness of hydrogen in the heating and transport sectors. Considering the current prices of different fuels, it is shown that hydrogen can be competitive in the transport sector if it is unencumbered by various environmental taxes. The second part of the paper deals with hydrogen production in the context of secondary control ancillary service provided by a case study power plant. Namely, hydrogen can be produced during the time period when there is no demand for extra electric power within a secondary control ancillary service, and thus the economics of power plant operation can be improved.

“…The demands for efficient and flexible production have established the importance of an autonomous production-management level acting as a kind of interface between the requests from the businessmanagement level and the factory-floor production control, as presented in Figure 1 (Anthony 1965, Hales 1989, Jovan et al 1998. At the productionmanagement level at least two essential activities are performed: (i) the transformation of a company's objectives into results and (ii) the optimisation of production.…”

“…Discrete and process manufacturing are terms that are often used to describe the nature of manufacturing operations where the process industry has several specifics compared with discrete industry that make it both complex and uncertain (Taylor et al 1981, Jovan et al 1998. The complexity arises primarily from the required linking of various sub-processes, each of which affects the quality of the final product.…”

The synthesis of plant-wide control structures is recognised as one of the most important production-management design problems in the process industries. This article proposes a closed-loop control structure utilising production performance indicators (pPIs) as a possible solution to simplify this problem. pPIs represent the translation of operating objectives, such as the minimisation of production costs, to a set of measurable variables that can then be used in a feedback control. The idea of closed-loop control at the production-management level using pPIs as referenced controlled variables was implemented on the procedural model of a production process for a polymerisation plant, and two types of controllers were tested: an experimental controller based on look-up tables, and an advanced model predictive controller (MPC). Preliminary results show the usefulness of the proposed methodology.
