Hyliion’s story is certainly one of alternative. Alternative embraced quite than prevented.
The corporate was based over a decade in the past with a transparent mission. CEO Thomas Healy had earned a Mechanical Engineering diploma from Carnegie Mellon and had recognized potential in a enterprise that helped transition 18-wheel semi-trucks from diesel to electrical.
In 2020, this ‘stereotypical start-up journey’ was given the prospect to speed up through a $1.5b SPAC-enabled public itemizing, and the next 12 months, GE Aerospace had been in contact to gauge Hyliion’s curiosity in coming into a brand new discipline, commercialising an in-development know-how, and adopting an additive manufacturing workflow that may be fully new to the corporate.
Although a frightening prospect, the timing was good. Six years into the corporate’s electrical automobile (EV) efforts, Hyliion’s hierarchy was turning into much less sure in its future as an EV entity.
“We noticed that the EV area was not heading in a great path,” Healy instructed the Additive Perception podcast. “Lots of our friends had been going bankrupt, it was robust to boost capital, the tempo at which fleets had been adopting new electrical autos was slowing down, prices had been larger, the mandates had been softening.”
The deal to accumulate GE Aerospace’s KARNO energy era know-how was accomplished in 2022 at a really palatable $37m, and quite than make KARNO a component of the enterprise, Hyliion has ‘gone all in’ on the know-how.
At the moment, it presents itself as an influence era firm and has taken KARNO from the midst of a product growth part to a commercialised product. When GE bought the know-how in 2022, it had iterated on the design of the primary KARNO product thrice. Hyliion went by way of one other couple of iteration cycles earlier than launching the KARNO 200 kilowatt energy module to market.
This product is a linear warmth generator that makes use of warmth as a gas supply to provide electrical energy. The premise, as Healy explains it, is to permit customers of the KARNO 200 kilowatt energy module to make their very own electrical energy on web site, quite than being reliant on the grid.
“For information centres the place the grid doesn’t have the capability that information centres want, now they’ll transfer to on-site energy era, and transfer quicker than they might earlier than,” Healy defined. “For those who take a look at a shopping center, it allows them to make their very own electrical energy cheaper than shopping for grid electrical energy. After which for those who take a look at purposes just like the navy, we’re the facility plant on board the brand new unmanned navy ship.”
Hyliion can also be within the means of creating energy era options that may ship megawatts of energy, with the know-how stated to be inherently scalable.
The problem, if there’s one, is the tactic of manufacture. Additive manufacturing was the popular methodology of manufacture at GE Aerospace, and has remained so subsequent to the transition into Hyliion. Technically, the complexity of the warmth exchangers means you’d wrestle to make the product every other method, however what Hyliion can also be having to content material with is the dimensions of AM machine construct volumes.
Hyliion’s 200kW KARNO module has been designed to suit throughout the 250 x 250 mm construct plate dimension of its Colibrium Additive M2 system (one of many older generations of the machine). There are M Line and X Line machines in operation at Hyliion – each of which boast larger construct volumes than the M2 – however whereas growth on bigger modules is ongoing, customers with vital energy era wants are being serviced with a number of 200kW items ‘strung collectively’ like an EV automobile battery pack. That works out as one unit per construct on the M2 machines, two items per construct on the X Line, and 4 items per construct on the M Line.
As Healy explains on the Additive Perception podcast, the KARNO energy era merchandise work equally to Stirling engines, whereby a heating and cooling course of is carried out 20 occasions per second. When the gasoline contained in the chamber is heated, it drives a piston to generate electrical energy. The cooling then resets the cycle.
Whereas this can be a 200-year-old class of engine, they’ve usually been troublesome to fabricate. Additive manufacturing, nonetheless, has been capable of deal with the complexity of the design and permit the likes of Hyliion to take these options to market.
“These machines are fairly common in what they’ll print,” Healy stated. “One of many nice issues about additive is it doesn’t actually care if it’s printing a block of steel or an especially advanced half. It’s simply lasers going round which might be melting layer by layer and increase no matter construction you need. And it behoves you to make as advanced a component – clearly, if they’ve a profit – as attainable.”
Hyliion has managed to commercialise the KARNO energy era know-how inside only a few years, regardless of having little-to-no additive manufacturing experience previous to the KARNO acquisition. When the transaction was full, nonetheless, Hyliion built-in not simply the IP, however the crew behind the IP. Josh Mook, now the Hyliion CTO, was among the many founding members of the KARNO know-how inside GE and is credited with having assembled a ‘rockstar engineering crew’ with ‘the most effective designers for additive’ on this planet as Hyliion regarded to carry KARNO to market. This crew shouldn’t be solely pushing ahead with the event of KARNO merchandise, however because the crew grows, working to coach new recruits on Hyliion’s additive manufacturing ‘secret sauces.’
On the newest Additive Perception podcast, Healy goes on to share views on the AM enterprise case for the KARNO energy era know-how, constructing out an inside AM functionality, and the place he’d prefer to see AM know-how enhance.
