SEI will be taking a guided tour of Vestas’ North American Headquarters in Portland, OR on Saturday February 22nd. If you are interested please contact Zach Jones at email@example.com.
We will be touring Pacific Biodiesel‘s production facility in Salem, OR on Saturday April 27th. This is an opportunity to see how biodiesel is produced on a commercial scale, right here in Oregon.
We are departing from the parking lot between Gilbert and Winegar hall at 10:00am sharp on Saturday morning. Please arrive by 9:50 at the latest.
To reserve a spot, bring $10 to the main office in Gleeson Hall. We are limited to 20 spots, so get in there before we run out of spaces! Reservations are first-come, first-serve.
The Sustainable Energy Initiative presented a screening of “Switch” in the LaSells Stewart Center on January 29, 2013. Switch is a documentary presented by Dr. Scott Tinker that explores the realities and prospects of renewable energy all around the planet. SEI also presented a sustainability expo and a Q&A discussion panel with energy experts. Keep reading for a summary of the event, pictures, and (soon) a video of the discussion panel.
Prior to the film screening, SEI hosted the OSU Sustainability Expo. University sustainability organizations informed and engaged students and community members about what OSU is doing to promote sustainability and ways to get involved.
Afterward, attendees sat down to watch the “Switch” film. Documentary stereotypes are thrown aside by pleasing camerawork and narration as Tinker guides viewers through a journey in search of the answer to a very important modern question – What will it take to transform our energy infrastructure into something we can sustain responsibly? He visits locales ranging from Iceland to the plains of Texas to urban India, exploring both renewable and nonrenewable energy sources. While he examines many promising possibilities, Tinker also concludes with a hard truth – No single panacea exists for Earth’s energy problem. The physical, economical, and political hurdles Tinker uncovers lead him to predict it will take small steps and many different energy sources to power the future.
SEI concluded the event with a panel of six sustainable energy experts from a variety of fields. Audience members had the opportunity to ask the panel questions about the film and sustainable energy. A video recording of the panel discussion will be uploaded in the next few days. The experts panel included:
- Brandon Trelstad: Sustainability Coordinator, Oregon State University
- Dr. Jose Reyes: Chief Technology Officer, NuScale Power
- Sean Moran: Wave Energy Ocean Test Facilities Manager, NNMREC
- Dr. Paul King: Business and Outreach Manager, National Energy Technology Laboratory
- Bill Drumheller: Senior Policy Analyst, Oregon Department of Energy
- Dr. Steve Potochnik: Co-founder and process engineer, Trillium Fiber Fuels

- The big picture:
- Hydrogen is the most abundant element in the universe.
- It is the 8th most abundant element on Earth.
- Earth has insufficient gravity to maintain free hydrogen.
- Chemical Reactions:
- Steam Methane Reforming
- Hydrocracking (uses H2 to break carbon chains)
- Haber process (uses H2 to produce ammonia)
- Hydrogen as fuel:
- Hydrogen can be burned just like natural gas
- Fuel cells
- Produce electricity at a 40-50% efficiency.
- Have a combined heat & power 70-95% efficiency.
- Protons are separated from electrons by a membrane which creates a potential.
- Use a 0.7 V/cell.
- Made of stacks of cells
- Platinum-based is the traditional
- carbon- or nickel-based
- Hydrogen Stroage
- The good news: Hydorgen has more energy per gram capacity than traditional fuels
- The bad news: Its density is much less than traditional fuels, so it is less useful in that respect
- Current Technologies
- liquid hydrogen
- energy cost 30%
- boil-off losses ~ 50% in 10 days
- compressed hydrogen
- energy cost 15-20%
- low energy density

- metal hydrides
- minimal energy cost, dense hydrogen packing
- very heavy
- expensive (because of the use of rare metals)
- useful for small scale, not large scale
- chemical conversion
- using water or ammonia
- When volume is not an issue, hydrogen storage is very useful
- however, we still need a breakthrough
