Achieving flexibility through energy storage will be a key element in the transition to a low carbon energy grid. Decision making around investment in energy storage assets is a challenging task, and is typically reliant upon evaluating the expected performance of the planned asset on the basis of a...

The performance of battery energy storage systems (BESS) along their lifetime is significantly influenced by their degradation. The rate of degradation depends on stress factors such as the state of charge, charge-discharge rate, and depth of cycle, but evolves differently for every individual battery....

Solar photovoltaics (PV) on building rooftops is a major contributor to the decarbonization of energy systems and provides electricity close to consumption. However, high shares of PV challenge distribution grids and require energy storages due to the fluctuating daily and seasonal production profile....

Inverter based resources (IBRs) are capable of providing grid services to ensure system stability. Manufacturers of such IBRs are required to certify their products according to the testing procedures of each individual country to meet the grid connection requirements of the target markets. When various...

A novel model was used to simulate how an existing district heating (DH) network for Holywell Park, Loughborough University (Loughborough, UK) could be transitioned to low/zero carbon heat. A simulation which includes heat pumps (HPs) and evacuated-tube solar thermal collectors (ETSTCs) to both provide...

As data centers (DCs) are the backbones of information and communications technology (ICT), internet and big data, the utilization of energy by DCs has increased exponentially, which presents a significant impact on the environment. To simultaneously solve the dilemma of DC huge amount of electricity...

This study investigates the methanation of green electricity from a combined wind and PV power plant with a peak capacity of 250 MW in three different countries (Chile, UAE, Tunisia) and the transport of the produced methane to Austria. The production costs were calculated through a simulation on an...

Renewable energy can significantly reduce global CO2 emissions, both directly by reducing the use of fossil-based energy sources and indirectly through power-to-X pathways. These pathways facilitate the production of various fuels and chemical feedstocks, offering alternatives to fossil-based products....

Renewable Metal Fuels (ReMeF) have great potential to store renewable energy for several months. A thorough criteria evaluation of possible candidates was conducted, considering (1) abundance in the Earth's crust, (2) world reserves, (3) market price and its development, (4) energy density, and...

Mid-sized thermal energy storage (TES) systems, especially in the distributed sector, have received little attention for public buildings. Validation of such systems, especially for the use of multiple renewables with different operating modes using CFD simulations, is still pending. The objective of...

An experimental study was undertaken to evaluate the thermal performance of a novel compact latent heat thermal energy storage (LH-TES) system.

Within the Collaborative Research Center 1244 at the University of Stuttgart, a facade-integrated solar cooling system for lightweight buildings is being developed. It addresses the reduction of CO2 emissions twofold. First, lightweight buildings require less concrete but require cooling due to their...

One problem with utilising solar renewable energy sources, for domestic space heating and domestic hot water in the UK is the mismatch between energy supply and energy demand due to the seasonal variation. One way to mitigate this phenomenon is to utilise seasonal thermochemical heat storage. 13X molecular...
