Hybrid solutions that combine multiple renewable energy sources, such as solar power and hydro power, are gaining popularity as a means of meeting the growing energy demands while minimising environmental impacts, but also as an opportunity of connecting solar power plants to the grid in areas where this might not be possible unless large investments are made. This master thesis aims to evaluate t
The carbon intensity is an important metric that provides a clear measure of the environmental impact associated with the electricity use. Carbon intensity of electricity use is differentiated into CO₂ equivalents per kilowatt-hour, which standardises the measurement by expressing the emissions of various greenhouse gases in terms of the equivalent amount of CO₂ based on their global warming poten
The interest in self-consumption of PV electricity from grid-connected residential systems is increasing among PV system owners and in the scientific community. Self-consumption can be defined as the share of the total PV production directly consumed by the PV system owner. With decreased subsidies for PV electricity in several countries, increased self-consumption could raise the profit of PV sys
The transition towards renewable energy and electrification is expected to accelerate in the coming decades. This change is being studied by several actors, in Sweden most notably by Svenska kraft- nät, the Swedish TSO. They have recently constructed four different scenarios, two of which explore a future with a doubling of electricity consumption from year 2022 to year 2045. These two scenarios h
In order to decrease the dependence on fossil fuels it is of paramount importance that renewable sources are used as effectively as possible. Therefore it is necessary to store excess energy when supply is higher than de-mand. One way to do so is by storing the energy as compressed air in a porous aquifer. The Lund Sandstone in the Kyrkheddinge area, Skåne, southern Sweden, has previously been inv

The free energy of binding between avidin and seven biotin analogues has been calculated with the molecular mechanics Poisson- Boltzmann surface area (MM/PBSA) method. We have studied how the force field and the method to generate geometries affect the calculated binding free energies. Four different force fields were compared, but we saw no significant difference in the results. However, mixing t
Hur akviferlagers miljöpåverkan beskrivs i ansökningar och hur det påverkar tillstånd Akviferlager är den större och effektivare kusinen till jord- och bergvärme. Systemet använder sig av grundvattnet och ger både värme och kyla. Miljöriskerna är större än för enskilda villors jord- och bergvärme. Men hur väl utvärderas detta? Det finns ett hundratal akviferlager i Sverige som betjänar allt frå
Framtidens energilagring banar väg åt förnyelsebar elenergi Andelen förnyelsebar elenergi på marknaden ökar ständigt. En negativ aspekt med dessa källor är att vi inte kan kontrollera när energin skall vara tillgänglig – vindkraften behöver vind och solkraften behöver strålande sol. För att överkomma dessa motsättningar och göra energin mer tillförlitlig behöver vind och solenergi kompletteras meIn this study, different membranes were tested for their use in a vanadium redox flow battery (VRB). The membranes were first tested under charge-discharge operation of the VRB over four charge-discharge cycles at different current densities (20 mAcm-2, 40 mA cm-2 and 60 mAcm-2) and the corresponding cell performance was evaluated in terms of total energy efficiency (EE), coulombic efficiency (CE)
One of the world’s brightest and most powerful lights is created at MAX IV. Using the lights from MAX IV, scientists can understand how materials are built and how they can be used better than ever before. Exploring materials with lightsAt MAX IV, scientists accelerate electrons in a linear accelerator so that they travel at nearly the speed of light. The electrons then enter storage rings where

The need for sustainable renewable energy has been increasing due to the negative impact of non-renewable energy sources. With the unstable and sporadic nature of sustainable renewable energy, flow batteries show immense potential in mitigating these issues. Traditional vanadium and zinc-based flow batteries, as well as new flow battery systems, are now being researched extensively. Vanadium and z
Pneumatiska bromssystem i tunga fordon är oeffektiva ur energiperspektiv, artikeln beskriver mätningar som jämför pneumatiska och elektromekaniska bromssystem för en batterielektrisk buss.
Sverige har som mål att, år 2040, ha ett helt förnybart elsystem. Idag utgör solceller ungefär 0.2 procent av den totala elproduktionen, men deras marknadsandel ökar hastigt, och antas ha potentialen att leverera 5-10 procent av elproduktionen år 2040. Till följd av den växande solcellsmarknaden har även energilagring, i form av batteri, blivit allt intressantare eftersom man med batterier kan ökaSweden aims to have a completely renewable electricity system by 2040. Today, photovoltaics (PV) account for about 0.2 percent of total electricity production but are estimated to have a potential to deliver between 5 and 10 percent of total electricity production in 2040. The expansion of the PV market share has already started and is increasing rapidly. Because of the growing PV market, energy s
