    As a mean to reduce climate emissions and lower air pollution, electric vehicles has been embraced as one part of the solution. In recent years, electrification of the maritime sector (electric boats, ships and ferries) has also been prioritized by the Norwegian government and is a popular topic in research. One of the challenges, is how to charge these vessels efficiently. In Norway, the main focus has been on electric ferries, but also smaller electric boats for the fish farming and fishery industry has been developed. Charging solutions developed for large ships and ferries might not be suitable for smaller vessels. Their operation schedule and power/voltage level differ and other solutions should be evaluated.

    Small electric vessels today uses standard industrial socket outlets, where the vessel itself determines the charging power without taking grid capacity into account. Just as dedicated charging stations are highly recommended for electric vehicles due to safety reasons, a similar principle can be applied to electric maritime vessels. In addition to grid monitoring and safety, a charging station could communicate with the power grid and utilizing the available capacity without causing overload.

    The question is how to these functionalities should be developed and integrated, and according to what standard. Would international standards on shore connection (IEC/ISO/IEEE 80005 series) be viable solution, or should we look towards other sectors such as electric vehicles?

    This presentation discusses existing standards and charging solutions in the transport sector and their applicability to small electric maritime vessels. If charging solutions for onshore and offshore transportation could be based on common standards, the same fast-charging station could be used for electric boats and cars alike. This could reduce the total investment cost and allow faster electrification of the transport sector.

    Society depends on fossil resources such as oil, gas, and coal to satisfy our demand for energy as well as the thousands of products made out of carbon originating from oil (e.g. plastics, pharmaceuticals, paints). As fossil resources are not sustainable, alternative sources of carbon are needed. One such alternative source is the waste product of our oil consumption - carbon dioxide (CO2). In analogy to natural photosynthetic processes, CO2 can be used as a carbon source in the laboratory and industry for synthesis of organic molecules and fuels.

    The conversion of CO2 into useful products is generally referred to as Carbon Capture and Usage (CCU). This presentation will discuss the potential impact and challenges of chemical CCU. In particular, in order to employ CO2 as a carbon source, novel chemical processes have to be developed. I will present our CO2 conversion project CHOCO (site.uit.no/choco), alongside a brief overview of the status of CCU research in the Nordic countries and the research goals of the recently established Nordic Centre for CO2 Conversion (site.uit.no/nordco2).

    Electric vehicles (EVs) can contribute to reduced greenhouse gas emissions, as well as a reduction of local article and noise pollution. In order to contribute to reduced greenhouse gas emissions, EVs should be charged using electricity from renewable sources, such as solar energy, wind power, or hydropower.

    The number of electric vehicles (EVs) have increased rapidly in Norway, and battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs) now make up around 40% of the new sales of personal vehicles.

    The number of solar photovoltaic (PV) systems in Norway have also increased in the last few years, but the total installed power is so far low. There are only a handful of PV systems in the northern-most counties of Norway (Troms and Finnmark). However, studies at UiT The Arctic University of Norway has shown that the energy yield of a PV system in Tromsø is comparable to that in Northern Germany.

    We have conducted a scenario study of different integration levels of EVs and PV systems in Tromsø, and simulated the EV load and PV electricity yield. The energy balance, power peaks and load match between charging load and PV energy yield were studied.

    The EV load was simulated using a stochastic model based on travel survey data, and the scenarios were 10-100% penetration of EVs in the personal vehicle fleet. The current number of EVs (BEV + PHEV) in Tromsø is around 1400, accounting for around 4% of the personal vehicle fleet.

    The PV electricity yield was simulated using the simulation software PVsyst. The scenarios were PV integration on 10-100% of the available and suitable building area on roofs and facades. The suitable area was calculated using a method based on building statistics and rule-of-thumb utilization factors.

    The simulations were performed for spring and summer. The simulation study showed that the PV energy could cover the EV load for most combinations of scenarios, except those with a high EV level and low PV level. However, the temporal load match was not perfect, especially for home charging. Methods to improve the load match include local battery storage, smart charging strategies and combination with other renewable energy sources.
