PV module performance over time: assessing 26 years at the HSU Telonicher Marine Lab

In 1990, the Schatz Center installed 192 ARCO M75 photovoltaic (PV) modules at the HSU Telonicher Marine Lab in Trinidad, California, 150 m off the Pacific Ocean. Current voltage (IV) tests were performed on each module prior to the array’s construction in 1990, again in 2001 and 2010, and most recently in 2016 after the array was decommissioned.

Sustainable Futures Speaker Series: Debbie Page-Dumroese on August 31

Join us on Thursday, August 31 at 5:30 pm in Founders Hall 118, for a presentation by visiting soil scientist Debbie Page-Dumroese on the use of biochar to sequester carbon and improve soil resilience. Biochar is a porous, high-carbon material derived from exposing biomass to temperatures above 500°C in a low-oxygen environment. The resultant “char” is typically used as a soil amendment to increase water-holding capacity and nutrient retention.

Page-Dumroese has been a Research Soil Scientist with the USDA Forest Service Rocky Mountain Research Station for over three decades. Her work focuses on long-term soil productivity after harvest operation, sustainable harvesting, wood decomposition, and biochar. For the last ten years, she has been investigating the potential to reduce slash pile burns and limit wildfire risks by using onsite biochar conversion technologies.

Visiting Speaker Debbie Page-Dumroese

The Sustainable Futures Speaker Series is cosponsored by the Schatz Energy Research Center and HSU’s Environment & Community graduate program. For details on upcoming events or to request accessibility accommodations, email us at serc@humboldt.edu or call (707) 826-4345.

Waste to Wisdom Webinar: Wednesday, August 9

On Wednesday, August 9 at 10 am (Pacific), join SERC Research Engineer Mark Severy alongside Sevda Alanya, Richard Bergman, and Ted Bilek of the USDA Forest Service’s Forest Products Laboratory as they discuss results from a life cycle assessment and economic analysis of producing torrefied biomass from forest residues.

To register, visit the Waste to Wisdom site.

Energy Ladder Research: Exploring the adoption of off-grid strategies in rural Uganda

SERC is researching solar product use in rural Uganda, to better understand what motivates and empowers low-income energy users to adopt off-grid energy solutions. This year-long study utilizes quantitative and qualitative research methods to explore customer adoption and financing behavior for off-grid energy solutions.

The Energy Ladder Research project is an initiative of the UNCDF’s CleanStart Programme, launched in partnership with SolarAid/Acumen.

Farewell to Jason McMack and Jeff Mosbacher

This month, SERC Research Engineer Jason McMack and SERC Research Assistant Jeff Mosbacher depart for new adventures at the Colorado School of Mines. Both Jason and Jeff are graduates of the HSU Environmental Resources Engineering program, and will be pursuing master’s degrees in Mechanical Engineering at the School of Mines. Jason began as a SERC docent in 2014, and then joined the off-grid energy access team in the summer of 2015. He completed his bachelor’s in December 2016, and has since been employed full-time at the lab. Jeff joined SERC in 2015 as a student research assistant, working on a project examining the quality of LED lights sold in Bangladesh. Jeff has continued to work with the off-grid energy access team since, and completed his bachelor’s this May. We wish them both all the best in Colorado!

SERC and solar power in sub-Saharan Africa

In this week’s New Yorker magazine (issue: June 26, 2017), Bill McKibben reports on solar power development in sub-Saharan Africa, including the role of quality assurance testing offered by SERC and other labs in the Lighting Global network.

Clarification (for the New Yorker piece): SERC Director Dr. Arne Jacobson played a leading role in the creation and implementation of Lighting Global, a program jointly managed by the International Finance Corporation and World Bank. The international testing labs are part of the Lighting Global network, not subsidiaries of the Schatz Energy Research Center (SERC). SERC provides setup and training for Lighting Global affiliated labs in Africa and Asia, as well as off-grid product testing and standards development.

Report from the annual Waste to Wisdom meeting

SERC presented at the Waste to Wisdom annual meeting in Sacramento on May 17th. This public meeting brought together over one hundred academics, policymakers, project developers, community members, and equipment manufacturers from around the country to discuss the opportunities and challenges to increasing utilization of forest residues.

Arne Jacobson, David Carter, and Mark Severy presented on Biomass Conversion Technologies: System Performance, Case Studies, and Implications for California’s Forest Management. Using examples from our research, SERC engineers described the state of biomass conversion technologies with a focus on biochar, torrefied biomass, and densified briquette production. Our presentation hinged around identifying and discussing methods for overcoming the current challenges of scale, site infrastructure, feedstock quality, environmental safety, and market development that are holding back widespread adoption of these biomass conversion technologies.

SERC’s slide presentation and additional reports and presentations from this meeting are available from Waste to Wisdom.
