Advanced Power Systems

Advanced Space Power Systems (ASPS) will develop technologies and components to provide safe, reliable, and abundant advanced battery energy storage for deep-space human and robotic missions (and dual-use terrestrial applications). NASA’s efforts to pack more energy into today’s lithium ion batteries safely for use in space means astronauts can increase extravehicular activity from a few to more than 8 hours, and the technology advancements will likely be of benefit for commercial uses such as smartphones and hybrid cars.


Advanced Space Power Systems (ASPS) supports NASA’s technology goals in the NASA Technology Road Map Technical Area 3, Space Power and Energy Storage, and specifically subgoal 3-2: Store energy at the highest possible specific energy with sufficient durability in the mission environment and, in the case of rechargeable storage, sufficient cycle life. ASPS will develop technologies and components to provide safe, reliable, and abundant power for deep-space human and robotic missions (and dual-use terrestrial applications), including low-cost solar arrays, advanced batteries, and regenerative fuel cells. These technologies will be used in components and systems appropriate for a variety of applications that include extravehicular activity (EVA) life support systems, spacecraft, habitats, and rovers. ASPS technology development emphasizes advanced high specific energy and energy density batteries with flame retardant electrolytes, that will be matured and then demonstrated in prototypes of appropriate size, power, and mass relevant to the end application.

Abundant power expands the capabilities of every human and robotic mission, including missions to asteroids, planets, moons, libration points, and orbiting structures. Furthermore, abundant power provides benefits for all phases of space flight: vehicle operations, electric propulsion systems, and destination applications.

The Advanced Energy Storage Systems technology element, which is ASPS’s focus, has been divided into two categories of interest. Category One: “High Specific Energy System Concepts” focuses on system level battery technologies such as packaging and cell integration. Category Two: “Very High Specific Energy Devices” focuses on energy storage technologies that have the potential to go beyond present capabilities characterized by Li+ chemistry, while maintaining the required duty cycle and safety of any system operating in space.

Next-gen battery collaboration to develop ‘beyond lithium-ion space’ in space

(Source: The American Ceramic Society) There are few situations in life where two aren’t better than one. So the recently announced collaboration between the Department of Energy’s Joint Center for Energy Storage Research (JCESR), located at Argonne National Laboratory (ANL), and NASA Glenn Research Center spells good things for batteries, which are poised to receive […]

Women at NASA: Meg Nazario

As a senior in high school, I took a physics class. I loved the challenge of figuring things out, and I loved how math could be used to predict where a ball would land as it rolled off of a table. My teacher was amazing and helped keep my interest by making the subject so […]

Space Technology and Innovation | NASA Banking on Solar Electric Propulsion’s Slow but Steady Push

WASHINGTON — The list of technologies NASA says it needs for a crewed mission to Mars notionally envisioned for the 2030s includes large-scale electric propulsion systems that dwarf those used today aboard many satellites. Read Full Story

Hydrogen-Fueled Bus serves Cleveland RTA customers

CLEVELAND — The Greater Cleveland Regional Transit Authority (RTA), in coordination with NASA Glenn Research Center, has ‘launched’ a hydrogen bus project in Cleveland. Customers on various routes may now experience a quieter and greener ride, powered by hydrogen, not diesel. This vehicle began carrying customers in January 2013. Read Full Story

Cleveland’s RTA to unveil nonpolluting hydrogen-fueled bus

CLEVELAND, Ohio — RTA buses burn millions of gallons of diesel fuel yearly, their tailpipes belching nasty pollutants. But a potentially cleaner future is now on display, when a 40-foot coach fueled by hydrogen takes the road. Its tailpipe emits only water. Read more

NASA Partners with Community to Demonstrate Hydrogen Bus

What swallows Lake Erie water, motors quietly through the streets of Cleveland, and expels water good enough to drink from its tailpipe? It’s a brand new Greater Cleveland Regional Transit Authority (RTA) bus, part of a demonstration of clean, alternative transportation. NASA’s Glenn Research Center is supporting a community-based partnership with RTA, the Cleveland Foundation, […]
