Large DC Distribution

Trondheim Høgskoleringen 5, Trondheim

    Presenter: Dr. William Gullvik from The Switch / Yaskawa Environmental Energy Topic: DC distribution: advantages and challenges, with some solutions from The Switch Abstract: In the last 5-10 years we have seen a rapid increase in the demand for DC distribution in the marine market. This presentation gives a quick introduction to the difference between AC and DC distribution, advantages, and challenges. The Switch has dedicated solutions for DC distribution, and these are shown with special focus on the Electronic DC Breaker (E-DCB) and Electronic Bus Link (EBL) products.   Below is the recording and attached is a PDF of the presentation.

Professional meeting regarding Norway’s hydrogen strategy

Trondheim Høgskoleringen 5, Trondheim

  NEF Trondheim group and IEEE Power & Energy Norway invite to Professional meeting on Norway's hydrogen strategy Wednesday 5 May 2021, 18: 00-19: 30 Webinar on MS Teams Chair Erick F. Alves, NEF Trondheim / IEEE PES 18:00 Introduction Erick F. Alves 18:05 Hydrogen electric aviation: hype or flop? Jonas K. Nøland, NTNU Aviation is now at an intersection. Hydrogen as a fuel has recently been estimated as one important factor in enabling zero-emission aircraft. The presentation examines the competitiveness of different hydrogen-electric propulsion systems. It is shown how the choice of technology is very dependent on the flight segment one is looking at. The ordering solutions are those that adequately combine energy efficiency and power density, and maximize possible synergies on board. The most fuel-saving solution is to go for all-electric propulsion. 18:25 HAEOULUS and Raggovidda: How to start a hydrogen valley? Federico Zenith, SINTEF Digital A fundamental difference between battery and hydrogen is that hydrogen infrastructure does not exists in the first place. It is therefore extra challenges to use hydrogen, as more actors must coordinate their measures, preferably under the auspices of public bodies. We will see how the construction of a hydrogen factory in Finnmark will be completely up and how experiences can be transferred to other areas. 18:45 Green hydrogen: benefits and challenges for the electric power system Espen Flo Bødal, NTNU / SINTEF Energy Hydrogen production by electrolysis can help balance energy bar and enable the utilization of remote, high-quality renewable resources. In order to achieve a high proportion of renewable energy in the power system, we may be dependent on flexibility from electrolytic hydrogen production, but this depends on local conditions. 19:05 Discussion 19:30 Closing NEF Trondheim and IEEE-PES Webinar Norway's hydrogen strategy 5 May 2021 Background Hydrogen is an energy carrier that can contribute to emissions and to create value for Norwegian business and industry. In order for hydrogen to be a low- or emission-free energy carrier, it must be produced with no or very low emissions, such as by electrolysis of water with pure power, or from natural gas with CO2 management. Technology maturity and high costs are today key barriers to increased use of hydrogen, especially in the transport sector and as an input factor in parts of the industry. If hydrogen and hydrogen-based solutions such as green ammonia are to be used in new areas, the technology and solution must become more mature. Further technology development is important. In its recently published strategy, the government set an important goal to increase the number of pilot and demonstration projects in Norway, by contributing to and supporting technology development and commercialization. There is a broad focus on zero-emission technologies and solutions throughout the policy instruments, and many see hydrogen as and of the possible new industrial events in Norway. But what is the challenge we have ahead? We have gathered several talented people from the research community in Trondheim to give you a better overview. Information The seminar is open and free for everyone. Access via the link: NEF (Norwegian Electrical Engineering Association) is Norway's leading network of technical professionals specializing in electrical and energy engineering. We have around 850 members and hold approx. 25 events divided into 6 local groups around the country. The local groups meet regularly to listen to exciting lectures, socialize, discuss professional issues, build networks and promote collaboration between professional environments. The association is based on volunteerism and commitment, and our membership consists of people from both the power industry, industry, oil & gas, the consulting industry, construction and civil engineering. Ordinary membership costs NOK 795 a year. There are reduced prices for students, juniors and retirees. Membership is arranged via IEEE (Institute of Electrical and Electronic Engineers) is an international non-profit organization that promotes most people in the past for technology related to electrical engineering. The IEEE has approximately 420,000 members in 160 countries. The Power & Energy Society is the part of the IEEE that is involved in electricity and energy. IEEE PES 'goal is to be a leader in disseminating scientific information about electricity and energy. The Norwegian department offers for this purpose to organize meetings on current topics. Membership in IEEE costs $ 171 + $ 35 per year for PES. New member gets 50% discount first year. Own prices for students. Membership is arranged via the IEEE's website
