[font size=3]As renewable energy sources grow, so does the demand for new ways to store the resulting energy at low-cost and in environmentally friendly ways. Now scientists report in ACS’ journal Environmental Science & Technology Letters a first-of-its-kind development toward that goal: a rechargeable battery driven by bacteria.

Solar, wind and other renewable energy sources are gaining ground as nations work to lower greenhouse gas emissions and reliance on petroleum. But sunlight and wind are not constant, so consumers can’t count on them 24-7. Storing energy can make renewables more reliable, but current technologies such as lithium-ion batteries are limited by safety issues, high costs and other factors. Sam D. Molenaar and his colleagues from Wageningen University and Wetsus (The Netherlands) wanted to come up with a less expensive, sustainable solution.

The researchers combined, for the first time, two separate microbial energy systems: one that uses bacteria to form acetate from electricity and one to convert the produced acetate back into electricity. The researchers successfully charged the battery over a 16-hour period and discharged it over the next 8 hours, mimicking the day-night pattern typical for solar energy production. They repeated this cycle 15 times in as many days. With further optimization, they say the energy density of the microbial battery could be competitive with conventional technologies. Someday it could help us store energy from local renewable sources safely and at a lower cost than current options.

1. I certainly hope so

growing my energy in several ways is more appealing than growing some and having to buy others.

2. as long as I don't have to walk my bateria daily I'm good with this.

3. Exciting

I hope this or something like it becomes a real game changer. I applaud the advancements in battery technology and the efforts, such as the Gigafactory, but I am hoping for an energy revolution. The current energy evolution feels too slow.

4. Scientists have been playing around with this nifty idea for a while

But watch out. The biggest advances with this are yet to come. They involve genetic engineering!!!
