Meteorological Assessment of Vertical Axis Wind Turbine Energy Microgeneration Potentials Across Two Swiss Cities Located in Complex Terrain

Wind energy is the most mature renewable energy technology; however, its exploitation in cities is often met with skepticism. Thanks to their ability to operate at low wind speed regardless of direction, vertical axis wind turbines (VAWTs) offer an attract ...

Estimating the energy return on investment of forestry biomass: Impacts of feedstock, production techniques and post-processing

Louis Marcel Merceron

The Energy Return On Investment (EROI) is a recognised indicator for assessing the relevance of an energy project in terms of net energy delivered to society. For woody biomass divergences remain on the right methodology to assess the EROI leading to large ...

Experimental Study of Underground Heat Storage via Hydraulic Fractures

Jean Vincent Daniel Naftalski, Brice Tanguy Alphonse Lecampion, Mohsen Talebkeikhah, Tristan Liardon, Romain Nicolas Frédéric Möri

We present a laboratory setup to test the energy budget of underground heat storage in an otherwise impermeable rock through engineered fractures, a so-called Fracture Thermal Energy Storage (FTES) system. A hydraulic fracture is first created in a cubic s ...

An occupant-centric control framework for balancing comfort, energy use and hygiene in hot water systems: A model-free reinforcement learning approach

François Maréchal, Dolaana Khovalyg, Amirreza Heidari

Occupants' behavior is a major source of uncertainty for the optimal operation of building energy systems. The highly stochastic hot water use behavior of occupants has led to conservative operational strategies for hot water systems, that try to ensure oc ...

Affinity-Engineered Flexible Scaffold toward Energy-Dense, Highly Reversible Na Metal Batteries

Dou Du

The practical deployment of metallic anodes in the energy-dense batteries is impeded by the thermodynamically unstable interphase in contact with the aprotic electrolyte, structural collapse of the substrates as well as their insufficient affinity toward t ...

Fully Soft-Switched High Step-Up Nonisolated Three-Port DC-DC Converter Using GaN HEMTs

Marco Mattavelli, Elison de Nazareth Matioli, Georgios Kampitsis

In this article, a soft-switched nonisolated high step-up multi-input dc-dc converter is proposed. The proposed converter has overcome the hard switching problem of the conventional boost three port converter (boost-TPC) by providing zero-voltage-switching ...

Modeling of Ion Crossover in Vanadium Redox Flow Batteries: A Computationally-Efficient Lumped Parameter Approach for Extended Cycling

Christopher Raymond Dennison

In this work, we have developed a zero-dimensional vanadium redox flow battery (VRFB) model which accounts for all modes of vanadium crossover and enables prediction of long-term performance of the system in a computationally-efficient manner. Using this m ...

Constrained spectrum control using MPC

Colin Neil Jones, Jean-Hubert Hours

Well-known model predictive control (MPC) theory for constrained linear time-invariant (LTI) systems is extended to accommodate hard constraints and cost penalizations on the spectra of the system’s output trajectories. Thus the proposed method facilitates ...
