This two-part paper investigates the potential of ORC (organic Rankine cycles) for the exploitation of low-medium enthalpy geothermal brines. Part A deals with thermodynamic analysis and optimization, while Part B focuses on economic optimization.

This paper presents the design, simulation and optimisation of a small trigeneration plant supplied by geothermal and solar energies. Different technologies are implemented in a dynamic simulation model purposely developed for research scope: a 6kWe micro Organic Rankine Cycle (ORC); a 30kWf...

Latent heat thermal energy storage (LHTES) integrated active free cooling stores night time cold and serves as heat sink for cooling when demand rises. Passive buildings, albeit their advantages in limiting heat loss during winter time, are often paired with excessive internal overheating in...

Standalone renewable energy (RE) systems hold the most promising solution to the electrification of remote areas without utility grid access, while a feasible energy storage is a core part for achieving a continuous and reliable power supply since RE is usually intermittent and weather...

Distributed cogeneration has played a key role in the implementation of sustainable energy policies for three decades. However, increasing penetration levels of intermittent renewables is challenging that position. The paradigmatic case of West Denmark indicates that distributed operators are...

In this paper, safe techno-economic sizing methodology of a standalone photovoltaic system is investigated. It is proposed to size the system on the basis of solar radiation measurements. Then, Markov transition matrices (MTM) are used to simulate stochastic cloud cover sequences. Each sizing is...

The shift from centralized to decentralized energy provision has created an opportunity for a wide range of distributed energy resources. In deciding how to best serve their long-term energy needs, end consumers face a plethora of investment options together with complex regulatory instruments...

As a developing country, Malaysia has always faced the problem of rural electrification in its islands. Rural islands cannot be connected to the grid as it is economically not feasible due to the low number of residents. The high greenhouse gas emission of the diesel generator is unfavorable to...

We are assembled today to discuss the opportunities and challenges for expanding the sales of geothermally-generated electric power in a competitive utility market. First, however, I would like to note that growth in geothermal sales might not be a germane topic were it not for the early...
