Green Hydrogen Rocket Launch

Prime Lightworks is developing green hydrogen (H2) rocket engines for satellite launch vehicles that are fully reusable with zero carbon emissions. Our vision is to enable sustainable space travel with green H2 fuel for a circular clean aerospace economy.

This Reg CF offering is made available through StartEngine Capital, LLC. This investment is speculative, illiquid, and involves a high degree of risk, including the possible loss of your entire investment.

$23,953.65 Raised


Extraordinary potential of clean spaceflight: We believe our integrated H2 propulsion technology is at the nexus of two burgeoning industries (aerospace and renewable energy) with global applications well beyond the $5.7B annual satellite launch industry.*

Commitment to Earth and our environment: The satellite industry is growing rapidly, and we must address the resulting pollution. In our view, fully reusable launch vehicles using green H2 fuel could eliminate emissions and waste from satellite launches.

Proven aerospace industry experience: Founded by former SpaceX engineers, Prime Lightworks has already raised $2.9M+ in seed funding from Y Combinator, Angel Investors, and StartEngine, and now we are ready for more.

the pitch

Founded by former SpaceX engineers with decades of experience in the field, we believe the Prime Lightworks system may generate a revolutionary advantage in spaceflight environmental and planetary sciences, enabling clean orbital launch by developing a fully reusable satellite rocket launch vehicle based on renewable natural resources that do not produce greenhouse gas emissions. By investing in Prime Lightworks, you could help advance the green movement of the aerospace industry, while holding equity in an innovative company that could soon establish itself in a flourishing multibillion-dollar market.

Investigating the Future of Renewable Aerospace Propulsion Based on Green H2 Fuel

At Prime Lightworks, we are building a prototype hydrogen rocket engine combining green hydrogen fuel and launch vehicle reusability to reduce the environmental impact of satellite launches. We will test at our new facility at Brunswick Landing in Maine, with support from Maine Technology Institute and Midcoast Regional Redevelopment Authority.

Our Founder & CEO, Kyle Flanagan, has a wealth of experience from Harvard, CERN, Caltech/JPL, and SpaceX, having been entrenched in this world for years. Our strategy in the near-term is to identify a vendor of green hydrogen for initial testing, while our long-term strategy is to purchase green hydrogen generation infrastructure so we can produce our own propellant at the launch site.


Eliminating Emissions and Waste from Satellite Launches 

The current growth in satellite launches is causing a rapid increase in greenhouse gas emissions and waste. The average rocket launch using kerosene fuel emits 336 metric tons of CO2. Over 27,000 pieces of orbital debris, or “space junk”, are tracked by the Department of Defense (DOD) Space Surveillance Network (SSN), posing a catastrophic risk to satellites and spacecraft. (sourcesource)

Our plan is to create a sustainable and reusable rocket launch platform by integrating a variety of already existing technologies including green H2 generation, storage, and combustion. The use of green hydrogen as rocket fuel will eliminate CO2 emissions from propellant generation, while full vehicle reusability will mitigate orbital debris from launch vehicle waste.

Our beachhead market will be sales of orbital rocket launch services to SmallSat manufacturers and operators with environmental missions, such as Earth observation, weather monitoring, and climate science, who may be eager to launch on a green platform. In the long term, we believe supporting full launch vehicle reusability with green hydrogen generation infrastructure may further drive down the price of SmallSat launches as we phase out the growing waste from expendable launch vehicles and the rising price of fossil fuel extraction.


The Global Satellite Launch Services Market is a $5B+ per Year Industry

The global space launch services market was valued at $5.7 billion in 2021, and is predicted to grow to $14 billion by 2029 at a CAGR of 12% (Source, Source). Small satellites account for nearly half the global launch market and 94% of all satellites launched last year. Over 1,700 satellites were launched in 2021, with another 11,000 satellites predicted to launch by 2030 (Source, Source).

Recently, we have achieved the following milestones: 

  • We’ve raised $2.9+ million in seed funding from Y Combinator, Angel Investors, and StartEngine
  • Graduated from Cleantech Open Northeast 2022 Accelerator with support from Maine Technology Institute
  • Relocated to 2,000 square foot facility at Brunswick Landing in Maine + TechPlace prototyping space
  • Begun assembly of our prototype hydrogen combustion chamber system for static fire testing


Help Us Launch into the Future of Space

The vision of Prime Lightworks is to help satellite manufacturers and operators achieve zero emissions spaceflight by developing a fully reusable launch vehicle for small satellites using green hydrogen propellant. With your support, we plan to complete hydrogen rocket engine testing and arrange for launch vehicle testing, sub-orbital flight testing, and re-entry testing, as we prepare for our first pilot customer satellite launch. Join us in building a sustainable future where air and space transportation are fully renewable based on natural resources with zero emissions footprint. Thank you for believing in our mission – we truly appreciate your support!

Glad to see you back on StartEngine but also kind of rude that investors in the last round (2021) have literally not heard a single peep from you since.. When we invest and don't hear anything for two years, we assume our money is gone. Please fix this moving forward Kyle

Hi, I see no mention of patents. What protections do you have for this technology you are developing? Thanks. Blessings




Cancel anytime before 48 hours before a rolling close or the offering end date.



We want you to succeed and get the most out of your money by offering rewards and memberships!


Your info is your info. We take pride in keeping it that way!


Invest in over 200 start-ups and collectibles!

With Regulation A+, a non-accredited investor can only invest a maximum of 10% of their annual income or 10% of their net worth per year, whichever is greater. There are no restrictions for accredited investors.

With Regulation Crowdfunding, non-accredited investors with an annual income or net worth less than $124,000, are limited to invest a maximum of 5% of the greater of those two amounts. For those with an annual income and net worth greater than $124,000, he/she is limited to investing 10% of the greater of the two amounts.

At the close of an offering, all investors whose funds have “cleared” by this time will be included in the disbursement. At this time, each investor will receive an email from StartEngine with their Countersigned Subscription Agreement, which will serve as their proof of purchase moving forward.

Please keep in mind that a company can conduct a series of “closes” or withdrawals of funds throughout the duration of the campaign. If you are included in that withdrawal period, you will be emailed your countersigned subscription agreement and proof of purchase immediately following that withdrawal.

StartEngine assists companies in raising capital, and once the offering is closed, we are no longer involved with whether the company chooses to list shares on a secondary market, or what occurs thereafter. Therefore, StartEngine has no control or insight into your investment after the close of the live offering. In addition, we are not permitted to provide financial advice. You may want to contact a financial professional to discuss possible investment outcomes.

For Regulation Crowdfunding, investors are able to cancel their investment at any point throughout the campaign up until 48 hours before the closing of the offering. Note: If the company does a rolling close, they will post an update to their current investors, giving them the opportunity to cancel during this timeframe. If you do not cancel within this 5-day timeframe, your funds will be invested in the company, and you will no longer be able to cancel the investment. If your funds show as ‘Invested’ on your account dashboard, your investment can no longer be canceled.

For Regulation A+, StartEngine allows for a four-hour cancelation period. Once the four-hour window has passed, it is up to each company to set their own cancelation policy. You may find the company’s cancelation policy in the company’s offering circular.

Once your investment is canceled, there is a 10-day clearing period (from the date your investment was submitted). After your funds have cleared the bank, you will receive your refund within 10 business days.

Refunds that are made through ACH payments can take up to 10 business days to clear. Unfortunately, we are at the mercy of the bank, but we will do everything we can to get you your refund as soon as possible. However, every investment needs to go through the clearing process in order to get sent back to the account associated with the investment.

Both Title III (Regulation Crowdfunding) and Title IV (Reg A+) help entrepreneurs crowdfund capital investments from unaccredited and accredited investors. The differences between these regulations are related to the investor limitations, the differing amounts of money companies are permitted to raise, and differing disclosure and filing requirements.
