Project Aims to Improve Photovoltaic Panel Efficiency through Soiling Mitigation
NASA TEERM is working with the KSC Sustainability Program, the University of Central Florida (UCF) Florida Solar Energy Center (FSEC), and Florida Power & Light (FPL) to evaluate coatings developed to reduce soiling impacts on photovoltaic (PV) panel efficiency. Soiling is a build-up of dust, bugs, bird droppings, water spots, and other debris. Current soiling mitigation techniques include regular cleaning or reliance on rain events. Industry has begun developing protective coatings to maintain PV panel efficiency while reducing or eliminating current cleaning needs. In addition to evaluating the effectiveness of several commercial off-the-shelf coatings, an economic feasibility analysis will be included to determine if the cost of the coating is offset by its soiling mitigation performance and durability. The focus of this project will be on coatings that are suitable for application on panels already installed in the field, as opposed to being applied during the manufacturing process. This project was selected and awarded by the KSC Sustainability Steering Committee in February 2015, using recycling funds. The first phase will be a coordinated effort amongst the aforementioned stakeholders that includes selecting, procuring and installing the necessary equipment to collect and analyze the data with in interim test report due by February 2016.

NASA TEERM Testing Shows That Citric Acid is Comparable to Nitric Acid
NASA TEERM is working with NASA Centers (KSC, Stennis Space Center, Wallops Flight Facility, White Sands Test Facility), the NASA Corrosion Technology Laboratory (CTL), the Ground Systems Development and Operations Program (GSDOP), and Department of Defense (DOD) to evaluate citric acid as a safer alternative to nitric acid for passivation of stainless steel alloys. Nitric acid has numerous environmental and safety issues associated with its use. Citric acid is a bio-based alternative that alleviates those concerns and offers additional operational benefits, such as reduced costs. Stage 1 Testing is complete and thus far, citric acid is showing comparable performance to nitric acid with no issues associated with adhesion or corrosion resistance. Additional testing is underway looking at other alloys and expanded performance requirements.

Technology Evaluation for Environmental Risk Mitigation (TEERM) Support Contract Awarded to ITB, Inc.
The Environmentally Driven Risk Reduction (EDRR) contract that includes supporting the TEERM Program and is managed by NASA's Environmental Management Division was recompeted and awarded to the incumbent, ITB, Inc. of Dayton, Ohio. ITB will continue to develop and execute collaborative activities/projects with industry partners and other agencies such as DoD and ESA, to help improve NASA's ability to adopt new environmental or energy-related technologies to reduce unacceptable mission risks in a more proactive and cost effective manner, and to better position itself to respond to new global regulatory and business paradigms.

October 2014

The National Aeronautics and Space Administration (NASA) and European partners held the 12th annual International Workshop on Environment and Alternative Energy, October 21 - 24, 2014 at The Debus Conference Facility at Kennedy Space Center Visitor Complex. The theme of the workshop was “Increasing Space Mission Resiliency through Sustainability.” This event was hosted by NASA, the European Space Agency (ESA), and the Portuguese Center for Pollution Prevention (C3P). The Luso-American Development Foundation (FLAD) sponsored several Portuguese university students to attend the workshop, ESA sponsored one student from France, and NASA sponsored 3 students from universities in Florida.
150 individuals from 15 nations attended the workshop, including 26 students. Thirty-eight U.S. and international subject matter experts presented collaborative activities that are underway and sustainability measures that are being taken to increase resiliency of essential capabilities and space mission critical ground infrastructure required to support future missions.
