The impact of solar photovoltaics on the energy-industry transition in the Nordic and Baltic countries
(Elsevier, 29.07.2026)The Nordic and Baltic countries are transitioning towards net-zero energy systems relying on hydropower, bioenergy, and wind power, while rapidly falling solar photovoltaics costs are positioning it as a credible and ... -
Offset-free model predictive control for an active magnetic bearing system
(2026)Active magnetic bearing systems are challenging to control because the rotor is open-loop unstable, the magnetic force is nonlinear, and the coil currents are limited by the actuator hardware. Model predictive control is ... -
Flexible electric boilers as part of the energy system of the future
(2026)Decarbonising district heating through electrification is widely advocated, but its value within a carbon-neutral biomass combined heat and power (CHP) system is ambiguous. This thesis examines the cost and emissions effects ... -
Assessing energy justice in renewable energy scenarios for Sub-Sahara Africa
(2026)Transition to RE raises certain opportunities but also threats for the Sub-Saharan Africa (SSA) where enormous renewable energy potential coexists with energy poverty. The current thesis is intended to address the problem ... -
Materiaalin kuljetusputkiston sekundäärikannattimien suunnittelu
(2026)Tässä tutkimuksessa tutkittiin erilaisten sekundäärikannattimien soveltuvuutta materiaalin kuljetusputkistojen kannakointiin. Tutkimuksen tavoitteena oli selvittää erilaisissa sekundäärikannattimissa ilmenevät rasitukset, ... -
Sähkökattilan ja lämpöakun kannattavuus kaukolämmön erillistuotannossa
(2026)Voimakkaasti sääriippuvaisen uusiutuvan energiantuotannon osuus on kasvanut merkittävästi eteenkin viime vuosina. Tästä on seurannut myös sähkön hintavaihteluiden voimistuminen. Edullista, jopa negatiivishintaista sähköä ... -
WACC assumptions and sector coupling concept in 100% renewable energy systems
(2026)The transition to 100% renewable energy systems depends not only on technological choices but also on the financial assumptions used in modelling and the terminology applied to interactions among energy sectors. This ... -
Biomassan energiakäyttö nyt ja tulevaisuudessa Euroopan unionissa
(2026)Biomassa tarjoaa loistavan ratkaisun ilmastonmuutosta vastaan taistelemiseen ja fossiilisista polttoaineista irtautumiseen. Biomassalla tarkoitetaan biologista alkuperää olevaa tuotteiden, jätteiden ja tähteiden biohajoavaa ... -
LDR-50 liten häiriö- ja onnettomuustapauksien analyysi TRACE-laskentaohjelmalla
(2026)Energiantarve olosuhteista riippumattomiin energianlähteisiin on lisännyt kiinnostusta ydinvoimaan, etenkin uudet pienet modulaariset ydinreaktorit (Small modular Reactors, SMR) ovat olleet kiinnostuksen kohteena niiden ... -
Keravan Energian luontojalanjälki vuonna 2024
(2026)Luonnon monimuotoisuus heikkenee nopeammin kuin koskaan aikaisemmin ihmiskunnan historiassa, kun käynnissä on kuudes sukupuuttoaalto, jonka aiheuttajana on ihminen. Luontokadon hillitsemiseksi on tärkeää tunnistaa sitä ... -
Datakeskusinvestointien lämpöpotentiaali Suomen kaukolämpösektorille
(2026)Datakeskuskapasiteetin kasvu lisää sähkön kysyntää, mutta luo myös mahdollisuuksia hyödyntää hukkalämpöä kaukolämpöjärjestelmissä. Tämän diplomityön tavoitteena on tarkastella Suomeen suunniteltujen datakeskusinvestointien ... -
Utilizing a novel technology arc suppression coil in MV distribution network
(2026)This master's thesis investigates the applicability of a novel arc suppression coil (ASC) technology in a U.S. medium-voltage (MV) distribution network. Single-line-to-earth faults are the most common fault type in MV ... -
Revealing global opportunities for carbon dioxide removal through a spatially high resolved techno-economic assessment
(2026)Carbon dioxide removal (CDR) will require a portfolio of options, but their availability and cost vary strongly by location. This thesis presents a spatially resolved techno-economic assessment of geological carbon dioxide ... -
Electromagnetic assessment of a 2.7 MW, 15 000 rpm axially laminated anisotropic synchronous reluctance machine as an alternative to an induction machine
(2026)This thesis presents the electromagnetic design and comparative finite-element analysis of two magnet free high-speed machine topologies: an induction machine (IM) and an axially laminated anisotropic synchronous reluctance ... -
Systemwide carbon return on investment during the energy transition towards net-zero emissions
(2026)Attaining carbon neutrality goes beyond mere emission curtailment. It demands strict life cycle and upstream supply chain carbon investment reductions. In this study, seven global energy transition pathways by 2050 are ... -
Techno-economic analysis and environmental considerations of agrivoltaics in Southeast Finland
(2026)Agrivoltaics can combine solar photovoltaics generated electricity and agricultural production on the same land area. This thesis assesses the techno-economic feasibility of selected agrivoltaics configurations in Southeast ... -
Sulfanilic acid-functionalized kraft lignin as a multifunctional additive for poly(vinyl acetate)-based wood adhesives and composite film applications
(Elsevier, 01.07.2026)Many domestic and industrial applications, particularly wood adhesives and polymer composite films, continue to depend on petroleum-derived additives, which pose environmental and health risks. To overcome these challenges, ... -
