To make affordable green hydrogen a reality, 3M says ‘bring us your problems’

Hydrogen and oxygen pulse via skinny tubes round a crowded laboratory. Moments earlier than, the gases had been mixed as water.

From a lab bench inside 3M’s Maplewood, Minnesota, campus, huge electrical cables connect with metallic gadgets the dimensions of books. A surge of energy interacts with water shifting via a powder, turning the liquid into gases.

That is inexperienced hydrogen, the long-promised clear vitality. To carry it to a bigger scale and ship on hydrogen’s longstanding promise because the renewable gasoline of the longer term, 3M is investing within the trade and focusing analysis on decreasing prices to make it a cost-effective vitality possibility.

A kilogram of hydrogen comprises sufficient vitality to energy a median dwelling for a day.

“The problem is a kilogram of green hydrogen is about $4 today,” mentioned Invoice Weber, enterprise constructing director at 3M Ventures. “It gets really competitive if we get it down around $1,” which is what hydrogen prices when it’s constructed from fossil fuels and could be cheaper than natural gas.

3M—the corporate behind N95 respirators, Put up-it notes and a litany of digital and industrial parts for telephones, automobiles and producers—is targeted on local weather know-how because it continues to evolve.

This is not the corporate’s first crack at different vitality. It pioneered among the know-how that underpins inexperienced hydrogen manufacturing, however bought off that enterprise years in the past as a result of, Weber mentioned, the market wasn’t prepared.

3M is betting now’s the time to get the corporate deeply embedded within the probably revolutionary trade; a wave of federal assist for hydrogen, together with practically $1 billion for a “hub” in Minnesota and tax credit, helps.

“It’s an era in hydrogen where things are happening both fast and slow,” mentioned Tim Yamaya, a company entrepreneur at 3M Ventures. “We want to help speed the transition.”

This spring, 3M joined a $20 million funding spherical for Evoloh, a California firm that producers electrolyzers, the gadgets that use electrical energy to separate water into hydrogen and oxygen.

3M can be making an attempt to resolve the issue of retailer and transport inexperienced hydrogen. It has additionally partnered with main Korean ship builder HD Hyundai to develop liquid hydrogen storage tanks utilizing glass bubbles 3M makes for insulation.

Liquid hydrogen might be diminished to 1/800th the dimensions of the fuel—important for economical transportation—nevertheless it have to be held at extraordinarily low temperatures.

“We can only handle natural gas because we have a half-trillion-dollar infrastructure,” Pivovar mentioned.

By increase the infrastructure to extra cheaply produce and transfer hydrogen, 3M expects extra industries will be a part of the market. Extra demand will result in extra provide, pushing costs even decrease.

Nevertheless, there stays danger to investing in hydrogen with out the assure of widespread adoption.

Bryan Pivovar, a researcher on the Nationwide Renewable Power Laboratory, known as it a “a chicken and the egg problem where you need a chicken and egg at the same time.”

“The biggest problem with hydrogen is it’s not economical at a small scale, but if there are more players and it’s more ubiquitous all of a sudden it can reach that larger scale,” he mentioned. “We’re at a tipping point.”

To achieve a aim of hydrogen offering about 15% of worldwide vitality wants, Pivovar mentioned present inexperienced hydrogen manufacturing would wish to extend about 500-fold. Some massive steps towards which might be underway; gigawatt-scale vegetation may very well be on-line by the tip of the last decade.

“The good news is it’s more economical than it ever has been before, or at least less economically painful,” Pivovar mentioned.

In the meantime, the conservative Manhattan Institute calls inexperienced hydrogen a “boondoggle,” and says small modular nuclear reactors are a more sensible choice for emission-free vitality.

Almost the entire hydrogen produced right this moment is constructed from pure fuel and utilized in ammonia fertilizer manufacturing. 3M sees a chance to each swap that manufacturing to a extra sustainable course of and open a pathway to extra makes use of like steelmaking and transportation/gasoline cells.

Andy Steinbach’s lab could be the happiest place at 3M because of the surplus oxygen piped out of the mini electrolyzers lining the lab bench.

One of many gadgets has been operating for five,000 hours, and can run one other 75,000 hours to make sure the important thing 3M materials splitting water molecules performs so long as it ought to.

“These are long-term durability tests,” Steinbach mentioned.

That materials, nanostructured-supported iridium catalyst powder, is a traditional 3M innovation: It has been round for many years however solely not too long ago was enlisted to assist with hydrogen manufacturing.

A gram of the powder might help produce 100 tons of hydrogen whereas decreasing the quantity of uncommon and costly iridium wanted in electrolysis. Extra effectivity, decrease price.

“It all comes back to 3M’s goal of supporting the hydrogen economy through materials and processes,” Yamaya mentioned.

Weber mentioned 3M needs to be a go-to useful resource for the hydrogen trade, slightly than knocking on doorways to pitch options.

“We want the problems to come to us.”
