Skenaarioiden tavoitteet vaihtelevat 100% uusiutuvan energiajärjestelmän suunnittelusta aina kasvihuonepääs- töneutraalin yhteiskunnan suunnitteluun, ja skenaarion tavoitteella havaittiin olevan vaikutus energiajärjestelmän suunnitteluun. Skenaarioien välillä on suuria eroja biomassan saatavuuden oletuksissa, oletuksissa CCS:än käytöstä sekä synteettisesti tuotettujen energiaintensiivisten kaasujen ja nestei- den (PtG, PtL) tärkeydessä ja roolissa. Myös ei-energiasektoreiden kytkentä energiasek- toreihin vaihtelee skenaarioiden välillä. Keskeisiä tuloksia ovat teollisuussektorin pääs- tövähennystavoitteiden sekä biomassan saatavuudesta tehtyjen oletusten vaikutus PtG/PtL teknologioiden tärkeyteen osana energiajärjestelmää. Tämän lisäksi se, että teollisuus ja liikenne ovat kaikista vaikeampia sektoreita päästöjen vähentämiseen on myös vertauksen tulos. Skenaarioiden vertailusta käy ilmi, että tulevaisuuden energiajärjestelmien suunnitte- luskenaarioihin sisältyy merkittävä määrä epävarmuutta; aina teknisistä ratkaisuista sosiaalisiin, poliittisiin ja taloudellisiin kysymyksiin. Suomailaiseen terästeollisuuteen ja PtL teknologiaan kytkeytyvä investointipäätös analysoidaan Robust Decision Making (RDM) –menetelmällä, jota on suunniteltu isojen epävarmuuksien alla tehtyjen päätös- ten tueksi. Tulokset osoittavat, että PtL –investointi ei ole yhtä robusti vaihtoehto kuin monet muut investointivaihtoehdot, mutta että RDM –menetelmän sovelluksesta vas- taavanlaisiin tapauksiin voi olla hyötyä. RDM voi antaa syvemmän ymmärryksen ris- keistä, mutta sen käyttäminen vaatii enemmän aikaa ja sitoutumista kuin perinteinen teknillis-taloudellinen mallintaminen.

(Tech.) Tiina Koljonen, VTT Date 29.09.2017 Number of pages 99 + 26 Language English Abstract The comparison of four future renewable energy system scenarios yields that energy system design for futures with 100% renewable energy is greatly dependent on whether the objective is to design an energy system with 100% renewable energy or to reduce GHG emissions from society as a whole. The latter seems to increase the relevance of power-to-gas (PtG) and power-to-liquid (PtL) technologies as these have the capacity to abate emissions from some industrial processes. Common factors in the four scenarios compared are higher electrification of the energy system and deeper integration of the enery sectors transport, heating and electricity. Differences between scenarios include biomass availability assumptions, level of electri- fication of transport, the inclusion of CCS, and the role of PtG/PtL as well as the level of integration of non-energy sectors with the energy system. A main finding is that biomass availability assumptions vary greatly illustrating the uncertainty connected to future energy system research, and that these also seem to affect the role of PtG/PtL technolo- gies. In addition, the drivers for investment in PtG/PtL differ between countries, with the technology playing a larger role in balancing intermittent renewable electricity sources in the scenario that relies very little on bioenergy. Furthermore, the transport and industry sectors are found to be the two hardest sectors to decarbonise. A business case related to the integration of PtL technology in an existing steel mill in Raahe, Finland is studied with the decision supporting Robust Decision Making (RDM) method. Results indicate that other investment options are more robust to future uncer- tainties than the PtL option is, but that RDM can be a useful tool when evaluating deci- sions made under conditions of deep uncertainty. RDM can offer a deeper understand- ing of the risks in far-reaching decisions and offer new perspectives in energy system analysis. Simultanoeusly, it also requires more time and commitment than a normal cost-benefit analysis. Keywords Renewable Energy, Robust Decision Making, Power-to-gas , Energy System, GHG neutral, Neo-Carbon Energy 4 Preface This thesis is part of the Neo-Carbon Energy (NCE) project and the premis was to ex- amine if the application of Robust Decision Making sheds new light on investments in the technologies related to the NCE project. In addition to this, a comparison of similar projects in other countries was added to provide a broader context; are other countries projecting similar future energy systems or not? The answer to this question can shed light on the robustness of the assumptions that are part of the NCE project. The research for the NCE project is conducted by the Technical Research Centre of Finland VTT Ltd, Lappeenranta University of Technology (LUT) and Finland Future Research Centre (FFRC) at the University of Turku, and it is funded by the Finnish Funding Agency for Innovation (Tekes). The author wishes to thank the instructor Tiina Koljonen, the supervisor Sanna Syri as well as research scientists Juha Forsström and Eemeli Tsupari for their contributions to the research presented in this thesis as well as for their valuable support and comments. A sincere thank you also to all colleagues in the Energy Systems research group at VTT for their comments and support.

I denna rapport sammanställde och jämförde vi olika produktionsvägar och råmaterial utifrån ekonomiskt-, tekniskt- och klimatperspektiv för långsiktig implementation. En litteraturstudie utfördes för att samla information om hållbara flygplansbränslen. Det finns ett flertal sätt att producera hållbara flygplansbränslen och denna rapport jämför tre olika produktionsvägar: Hydroprocessed Esters and Fatty Acids (HEFA), hydrotermisk förvätskning (HTL) och elektrobränslen. Av dessa har enbart HEFA godkänts för användning som flygbränsle (april 2020). Rapporten jämförde även tre olika råmaterial: biomassa från skogen, matlagningsolja samt matavfall ur ett svenskt perspektiv. Jämförelsen utfördes med en Pugh-matris som var baserad på: minskning i växthusgasutsläpp, teknisk mognadsgrad (hur långt i utvecklingen har produktionsväggen kommit), kostnaden för bränslet, effektivitet och potentiell bränslemängd (hur stor del av svenska jetbränslekonsumtionen kan vardera produktionsväg täcka). För att sätta jämförelsen i ett långsiktigt perspektiv vägdes jämförelseparameterna till: potentiell bränslemängd - 30%, minskning i växthusgasutsläpp - 30%, pris – 20%, avkastning – 10% och bränslet mognadsgrad – 10% av total 100 poäng.

Here, 11we provide an in-depth review of alternative energy sourcing technologies for aviation revealed to date, which we 12classified into three main categories, namely liquid fuels (biofuels, electrofuels), electric aviation (all electric and 13hybrid), and carbon-free options (hydrogen-based, solar-powered). For liquid fuels, 10 pathways were reviewed, for 14which we supply the detailed process flow picturing all input, output, and co-products generated. The market uptake 15and use of these co-products were also investigated, along with the overall international regulations and targets for 16future aviation. As most of the inventoried pathways require hydrogen, we further reviewed six existing and 17emerging carbon-free hydrogen production technologies. Our review also details the five key battery technologies 18available (lithium-ion, advanced lithium-ion, solid-state battery, lithium-sulfur, lithium-air) for aviation, as well as 19the possible configuration schemes for electric propulsion (parallel electric hybrid, series electric hybrid, all electric, 20partial turboelectric and full turboelectric) and reflects upon the inclusion of hydrogen-powered fuel cells with these 21configurations.

  • Assessing the Sustainability Implications of Alternative Aviation Fuels
    WORKING PAPER 2021-11 © 2021 INTERNATIONAL COUNCIL ON CLEAN TRANSPORTATION MARCH 2021 Fueling flight: Assessing the sustainability implications of alternative aviation fuels Authors: Nikita Pavlenko, Stephanie Searle Keywords: Aviation, biofuels, low-carbon fuels Aviation faces large technical barriers to making a transition to hydrogen or electricity- powered airframes, so the industry will probably have to rely on liquid fuels through 2050. That is particularly true for the medium- and long-haul flights that generate two- thirds of aviation emissions. If the industry is to meet its long-term climate goal of cutting greenhouse gas (GHG) emissions 50% by 2050 without curbing traffic growth or using out-of-sector carbon offsets, sustainable aviation fuels (SAFs) will need to play a key role. SAFs can be used to generate in-sector GHG reductions when they supplant conventional petroleum jet fuel. In 2018, less than 0.01% of aviation fuel came from alternative sources (Hupe, 2019; Graver, Zhang, & Rutherford, 2019). While reducing petroleum consumption in aviation is an important objective for decarbonization, the specific types of alternative fuels used to displace petroleum will determine the net climate impact of any alternative fuels policy. A fuel’s feedstock and its conversion process—together called the fuel pathway—determine the fuel’s life-cycle GHG emissions. The European Union’s recently announced Green New Deal framework calls for a clear regulatory roadmap for the decarbonization of aviation, to be achieved using a combination of new technology, SAFs, modal shift, and improved efficiency (European Parliament, 2020). As part of this effort, the European Commission announced the ReFuelEU initiative to deploy SAFs to decarbonize EU aviation (European Commission, n.d.).

  • Extracellular Electron Transfer from Cathode to Microbes: Application for Biofuel Production Okkyoung Choi and Byoung‑In Sang*
    Choi and Sang Biotechnol Biofuels (2016) 9:11 DOI 10.1186/s13068-016-0426-0 Biotechnology for Biofuels REVIEW Open Access Extracellular electron transfer from cathode to microbes: application for biofuel production Okkyoung Choi and Byoung‑In Sang* Abstract Extracellular electron transfer in microorganisms has been applied for bioelectrochemical synthesis utilizing microbes to catalyze anodic and/or cathodic biochemical reactions. Anodic reactions (electron transfer from microbe to anode) are used for current production and cathodic reactions (electron transfer from cathode to microbe) have recently been applied for current consumption for valuable biochemical production. The extensively studied exoelectro‑ genic bacteria Shewanella and Geobacter showed that both directions for electron transfer would be possible. It was proposed that gram-positive bacteria, in the absence of cytochrome C, would accept electrons using a cascade of membrane-bound complexes such as membrane-bound Fe-S proteins, oxidoreductase, and periplasmic enzymes. Modification of the cathode with the addition of positive charged species such as chitosan or with an increase of the interfacial area using a porous three-dimensional scaffold electrode led to increased current consumption. The extracellular electron transfer from the cathode to the microbe could catalyze various bioelectrochemical reductions. Electrofermentation used electrons from the cathode as reducing power to produce more reduced compounds such as alcohols than acids, shifting the metabolic pathway. Electrofuel could be generated through artificial photosynthe‑ sis using electrical energy instead of solar energy in the process of carbon fixation. Keywords: Bioelectrochemical synthesis, Extracellular electron transfer, Cathodic electron, Electrofuel Background and/or cathodic reactions. BES has two categories An eventual replacement of fossil energy source with according to the direction of electron flow, microbial fuel sustainable energy system is unavoidable.

The study is made by CIT Industriell Energi on assignment of the Norwegian environment agency. The report complements an earlier report that gives an overview of value chains for the production of liquid advanced biofuels. Together these two reports give a quite complete picture of potential renewable fuel production in the shorter (5- 10 years) term. In addition, they describe the most relevant value chains for this time perspective and some of their more vital linkages. The current report includes two very different groups of transport fuel value chains – partly bio- methane which is fairly well-established; partly synthetic fuels, which are currently on a much lower technology readiness level. It should be pointed out that there is no specific logic behind putting these two groups into the same report, other than that they were not included in the former report. Consequently, the scope and methodologies for each of the groups differ, and they are therefore summarized separately below. Production of bio-methane for use in the transportation sector Production of bio-methane, currently as well as in the near future, is mainly based on the value chain of anaerobic digestion.

  • Sustainable Synthetic Carbon-Based Fuels for Transport: Policy Briefing
    Sustainable synthetic carbon based fuels for transport POLICY BRIEFING Policy briefing Politics and science frequently move on vastly different timescales. A policymaker seeking evidence on a new policy will often need the answer in weeks or months, while it takes years to design and undertake the research to rigorously address a new policy question. The value of an extended investigation into a topic cannot be understated, but when this is not possible good evidence is better than none. The Royal Society’s series of policy briefings is a new mechanism aiming to bridge that divide. Drawing on the expertise of Fellows of the Royal Society and the wider scientific community, these policy briefings provide rapid and authoritative syntheses of current evidence. These briefings lay out the current state of knowledge and the questions that remain to be answered around a policy question often defined alongside a partner.

Liao, Chair Man-made photovoltaic device is relatively efficient in converting sunlight to electricity, but the electrical energy generated is difficult to store. Current methods, such as chemical batteries, hydraulic pumping, and water splitting, suffer from low energy density or incompatibility with current transportation infrastructure. The biological systems, on the other hand, can store sunlight in high energy-density carbon-carbon bonds. However, the photosynthesis has low solar energy harvesting efficiency, for which no near-term improvements are in sight. One way to solve both problems is to combine man-made solar cells to biological Carbon dioxide (CO2) fixation and fuel production. Therefore, a microbial process to produce biofuels from CO2 and electricity is needed. In this work, we first used metabolic engineering methods to achieve the production of isobutanol, n-butanol, and 3-methyl-1-butanol (3MB) in a lithoautotrophic bacterium Ralstonia eutropha H16, which can utilize formate as the sole carbon and energy source.
