The data center of the future is made of algae bricks and runs on hydr

Yearly for the foreseeable future, Microsoft expects to construct 50-100 new data facilities to maintain up with buyer demand. That’s a problem for a corporation that has a aim to quickly be carbon detrimental—which means it sequesters extra carbon that it emits—and water optimistic, which means that it returns extra water to the setting than it makes use of. Proper now, regardless that expertise retains getting extra environment friendly, data facilities nonetheless use large quantities of power and water (to maintain the data facilities cool); globally, the business makes use of an estimated 200 terawatt-hours of electrical energy a yr, or greater than some nations.

Inside the firm’s datacenter “superior growth” group, researchers are exploring how future data facilities can change, with options from the comprehensible—hydrogen gas cell backup energy—to the far-out, like constructing the facilities out of algae bricks “We readily say the expertise we’d like for 5 and ten years out doesn’t largely exist but,” says JoAnn Garbin, director of innovation for the datacenter superior growth group. “We examine what’s wanted. After which we create it.”

The firm is shifting to 100% renewable electrical energy by 2025 and persevering with to shrink power use, however to remove its carbon footprint, it additionally has to rethink how datacenter buildings are constructed to keep away from the carbon footprint of supplies like concrete and metal. It’s testing, for instance, structural tubes made from mycelium, the robust root-like threads that develop below mushrooms. Bricks which might be grown from algae could be carbon detrimental, as a result of the algae shops carbon because it grows.

“We’re piloting each of these in small scale,” Garbin says. “They’re actually solely manufactured in lab scale proper now. Our aim in superior growth is to show that they’re one-for-one replacements from a efficiency standpoint, and structural standpoint…and then begin incorporating it and create that market to get them out of lab scale into industrial scale.” The group’s philosophy, she says, is that there are “no dumb partitions”—each part of a constructing and website issues for sustainability objectives, the identical approach each half of a tree performs a helpful function in nature.


The firm is additionally potential new supplies for expertise, together with circuit boards made from renewable materials. “The imaginative and prescient is that basically, you possibly can recycle, reuse, or biodegrade all the things that you just use,” says Karin Strauss, senior principal analysis supervisor in the Microsoft Research group. The firm now has a “round” center in Amsterdam that harvests elements from previous servers in order that the elements could be reused, decreasing digital waste.

Proper now, data facilities rely on diesel turbines for the uncommon events that backup energy is wanted. Final yr, Microsoft examined a proof of idea to make use of hydrogen gas cells for backup as a substitute, operating a row of servers on the new system for 48 hours. The subsequent exams will take a look at how the expertise performs in real-life situations. The firm is additionally working with suppliers to construct up a provide chain for the gas cells that doesn’t but actually exist. “We’re additionally working with the hydrogen business and different gamers which might be transferring into the business to determine how we develop the provide chain to help it, as a result of that’s, of course, one of the issues that is a limiting issue,” says Christian Belady, vice chairman of the Superior Improvement group. “This is the rooster and the egg drawback—the infrastructure isn’t but there.” The infrastructure additionally needs to be constructed to make hydrogen gas utilizing renewable sources slightly than fossil fuels.

Data facilities additionally normally use large quantities of water to maintain servers cool—a typical data center can require 3-5 million gallons of water a day, as a lot as a metropolis of 50,000 individuals. Microsoft studied how servers carry out at greater temperatures, and is adjusting temperatures upward, which it expects will shrink water use by 95%.  It’s additionally testing another known as liquid cooling, a technique that submerges servers in a non-conductive liquid and removes warmth in a closed loop, which additionally saves power.

The firm is additionally eager about new methods to work together with ecosystems exterior every data center. Round a data center in Amsterdam, for instance, it’s restoring a forest and wetland. “It supplies the visible screening, the noise screening, the beautification that we might typically go for in our landscaping, however then it goes additional to unravel for biodiversity and water purification, soil well being, and stabilization and all of these issues that our system solves that nature does inherently,” says Garbin. “That underlying premise of biomimicry is actually how can we perform like nature? So it’s actually a primary pilot of that mindset and these instruments.”
