A team of researchers from Harvard have developed a breakthrough in battery technology that can store renewable energy in a non-toxic, non-flammable, safe, and low cost way
Batteries of this nature are paired with the collection of renewable resources “to store massive amounts of energy sources from solar and wind so that we can reuse it when the sun goes away, or the wind stops blowing," according to Kaixiang Lin, a member of the research team and a Harvard graduate student.
Many members of the research team believe that the development of a cost-effective, environmentally friendly flow battery can have significant implications in the energy and resource issues the future.
"This is the greatest problem facing humanity this century," said Professor Michael J. Aziz, the project’s principal investigator. "Any efforts to mitigate this problem could be very well appreciated."
According to Qing Chen, a postdoctoral fellow in Materials Science and Mechanical Engineering who is also a member of the research team, the improved battery is already on par with its less green alternatives, but the team plans on continuing to improve its efficiency.
With the ability to store energy, people will not need constant access to a power grid, which cuts down on cost, and allows for local production of energy, said Lin.
According to Aziz, one-fifth of the world’s population does not have access to electrical grids on a day-to-day basis. This technology could revolutionize their energy accessibility, while remaining eco-friendly.
The team’s principal goal is to make alternative renewable sources less expensive than non-renewable energy, explained Roy G. Gordon, one of the lead researchers of the battery’s chemistry and a professor of chemistry and materials science at Harvard. "Then we'll have a real stampede to clean energy sources, when it is actually less expensive.”
In three years, the research team hopes to have fully developed a commercially ready battery suitable for single family homes.
They have sufficient funding for now, but after the spring of 2017, Aziz said he is unsure who will provide capital. They will seek funding to sustain research through at least 2020.
Currently, the team is working to continue to find additional compounds to integrate into the battery. Though he didn’t specify the details of the compounds, Lin said that they might be “greener and cheaper.”
