How SpaceX Influenced Critical Energy's Geothermal Innovation
Spencer Jackson, once a key engineer at SpaceX, is now placing a bold $19 million bet on geothermal energy. What’s striking isn’t just the cash—though it’s a big sum—but the intent: taking hard-won lessons from rocket engineering and aiming them right at one of climate tech’s most stubborn frontiers. After years of watching aerospace talent migrate to new industries, it feels like the renewable sector is finally getting the expertise (and seriousness) it deserves. There’s a sense that the old barriers keeping geothermal from the energy spotlight are starting to crack—and frankly, it’s overdue.
VTechX Intelligence: Engineers are on the move. They're shifting from aerospace to the renewables sector at an impressive rate. This influx of talent—coupled with established technologies—could spark a wave of innovation. Particularly, geothermal energy, which hasn’t seen much progress, stands to gain a lot. Transformation in energy hardware could happen sooner than expected, reflecting a much-needed catch-up to modern standards.
Why Geothermal Energy Is Gaining Investor Attention
Geothermal power is the perennial underdog of renewables, usually playing second fiddle to solar and wind in the headlines. But the scale of what’s untapped here is honestly eye-opening: more than 42 terawatts of geothermal capacity lies dormant, according to the International Energy Agency—yet most investors seem distracted by nuclear fusion moonshots. The Critical Energy fundraise, led by Susa Ventures and Upfront Ventures, feels like a strong signal that this pattern could finally be shifting. Their focus on modular turbines for geothermal plants isn’t flashy, but it’s exactly the kind of practical step this field needs. If money and attention start flowing in, geothermal could finally get out of its holding pattern. For me, the question is why this didn’t happen sooner.
How Aerospace Innovations Propel Geothermal Technology Forward
Jackson’s SpaceX pedigree isn’t just for show—it’s shaping the entire playbook at Critical Energy. The company is borrowing from rocket engine design and adapting it for geothermal turbines, chasing higher efficiency and reliability. There’s something refreshing about seeing aerospace manufacturing principles—mixing custom components with off-the-shelf parts—applied to an industry that’s felt stagnant for too long. Their first 2.5 megawatt plant, set for 2027, doesn’t sound huge, but the ambition is obvious: iterate, scale, and move fast, just like in rocket launches. I like that they’re not chasing hype—they’re working on things that might actually get built.
Bridging the Turbine Shortage in Geothermal Energy
It’s wild that in 2024, geothermal’s biggest bottleneck is still the time and cost of building turbines. Jackson is blunt: traditional turbines take ages to build, which kills momentum for new projects. Critical Energy’s answer—factory-assembled modular turbines—could finally break this logjam. If they pull it off, it’ll make geothermal genuinely appealing to developers who’ve been burned by delays. I’m skeptical of silver bullets, but this is the kind of hardware fix that could open up the whole sector. It’s about time someone tackled the nuts-and-bolts problems head-on.
What Critical Energy's Vision Means for Geothermal Power
Jackson’s ambitions are nothing if not audacious. He wants to see Critical Energy cranking out turbines capable of delivering gigawatts of power every year by the early 2030s—shooting for 300 gigawatts annually by 2045. Those numbers are staggering, not just for geothermal but for the entire renewables landscape. If even half of this vision materializes, it could force governments and utilities to seriously rethink how they approach energy planning and infrastructure. For me, it’s the sheer scale of the goal that stands out—this is the kind of moonshot thinking geothermal has always lacked.
What Challenges Lie Ahead for Critical Energy's Geothermal Plans?
There’s no shortage of obstacles here—geothermal still gets overlooked by investors, and the field badly needs more technological breakthroughs. Yet, the pace of change is picking up, and companies like Critical Energy are pushing the sector in the right direction. I think the real wild card is the oil and gas industry. With their drilling know-how, they’re uniquely positioned to accelerate geothermal growth—if they choose to get serious about it. As capital pours in and new players jump aboard, it’s worth wondering how competition and control will evolve in what’s suddenly becoming a crowded field.
VTechX Take
Critical Energy, led by Spencer Jackson, is poised to disrupt the geothermal sector by leveraging aerospace engineering principles to develop modular turbines, which could significantly reduce project timelines and costs. If successful, this approach will likely compel traditional turbine suppliers to innovate or risk losing market share, as the demand for faster, more efficient geothermal solutions grows. Watch for shifts in investment patterns and project development timelines in the geothermal sector as new capital flows in.
What's Next for Critical Energy's Geothermal Ambitions?
Critical Energy is making headlines, but the real test is yet to come. If they can ramp up production and prove their modular turbines deliver on both cost and speed, the next five years could see geothermal finally break out of its niche status. Is this the tipping point where geothermal steps out of the shadows—and if so, will the industry be ready for the added scrutiny and competition? The stakes have never felt higher for a technology that, until now, has been flying under the radar.
