Our mission is to reduce noise, greenhouse gas emissions, local air pollution and provide local energy independence for remote communities.

Hydrocube(TM) Retrofit Services is a subsidiary business of the nonprofit Hydrocube.org, operated at “arm’s length”.

We take existing gasoline snowmobiles, off road vehicles (ORVs) and other light vehicles with minimal regulation, and we upgrade them to run on highly reliable, long range, cold-climate-capable hydrogen fuel cells.

We are setting up a workshop in an industrial area of Whitehorse, Yukon, Canada as well as a small team of traveling vehicle retrofit specialists that can do the work on site using your local workshop, some tools we bring with us, and some of your personnel to perform hands-on labor. Our specialists will conduct staff training before the retrofit proceeds and quality assure every vehicle that is produced.

Who We Are:


Stefan Weissenberg – Founder and lead Zero Emission Vehicle Integration Specialist (ZEVIS).

Hi, my name is Stefan. I have a bachelor’s degree in aeronautical engineering and ran a drone manufacturing company for 5 years.

The company was established to build purpose-made drones for volunteer search and rescue (SAR) teams and back-country wilderness adventurers, but we discovered wider markets for our rugged, weatherproof drone: police departments, the military, oil and gas companies and wealthy agriculturalists.

We made several sales to American clients and were featured on CBC, CTV News Vancouver and Gizmag. For 1 month I lived in Xiamen, Fujian, China working on a licensing and production deal with a Chinese investor.

After taking some time off for personal reasons, I decided to shift and focus my energy on solving climate change, the defining challenge of our time.

In February and March I like to go to Haines Pass, a beautiful remote place to go back-country skiing. I drive there, park, put on touring skins and go enjoy the peace and quiet; that is, until someone revs up a gasoline snowmobile and it echoes throughout the entire valley. This unhealthy noise pollution, along with the reality of climate change impacting my community through increased wildfires and permafrost melting, motivated me to do something about it.

Learning about hydrogen fuel cells was part of my drone business; I was designing a long-range oceanic and Arctic drone named the “Albatross”. Lithium batteries don’t work well in the cold, and they are not good for long range applications. Gasoline or hybrid drives were never even an option I considered; even growing up (when I was still in climate denial) the smell of gasoline made me sick and I never quite knew why.

When I decided to stop attempting to “dronify” the world and start working on the clearly more pressing issue of climate change, I brought my experience in renewable hydrogen with me.

I am currently building a 450 square foot zero-carbon-emission tiny-home in Destruction Bay, Yukon, Canada.

Funding (planned):

Government grants for renewable energy development:

  • Canadian federal government
  • State, provincial and territorial governments
  • First Nation / Inuit / Alaska Native and other indigenous governments

Private investment:

  • Private investors (VCs, Angels, etc. with very strong environmental values)
  • Electric utilities looking to stabilize and de-carbonize their diesel or LNG-powered grids (by using summer surplus energy for hydrogen fuel production and storage that can be put back on the grid in winter or used directly for vehicle fuel)
  • Hydrogen fuel cell vehicle manufacturers (Toyota, Honda, Nissan, etc.) looking to help engage communities about the hydrogen economy and increase uptake of larger scale hydrogen fueling infrastructure


  • We will occasionally run Kickstarter and other crowdfunding campaigns to help raise money for certain clients (especially nonprofits and Indigenous governments) to buy a clean, quiet hydrogen fuel cell snowmobile / ORV fleet. Please check back here regularly

Interested in joining us?

We are currently looking for:

  • CEO / Business Development Manager – commissioned sales manager, customer outreach
  • Electrical Engineer/s – assist with prototype snowmobile integration
  • Part time Legal Assistance – Incorporation, shareholder agreements, regulatory compliance

Currently we are not offering salaries for these positions until we gain more funding. Partners will receive:

  • Commission on sales (for CEO / Business Development manager only)
  • Equity earned for all your unpaid labor
  • The chance to work on something meaningful – climate change mitigation.
  • Extremely flexible hours (part time OK) and work location (work from home or anywhere)

Please contact us with your resume (or a link to your LinkedIn profile) and a brief cover letter.

Statement of Principles:

1. We strive to meet the United Nations’ climate goals, which seek a carbon dioxide emissions reduction (from 2018 levels) of 45% by 2030 and 100% by 2050. Renewable hydrogen fuel technology has the potential to eliminate all carbon dioxide emissions in remote communities by 2050 (except for aircraft and CO2 from natural sources) at a reasonable cost to developed nations.

2. Our renewable energy systems must have zero harmful emissions during operation.  We acknowledge and try to minimize greenhouse gas and other emissions during manufacture and shipping to us of our system components.

3. We are a social and environmental enterprise. Our primary purpose is to reduce greenhouse gas emissions as much as possible. We see monetary profit as a means to realizing our end goals, not as the end itself.

4. We are a small, focused, technology integrator organization. We focus our energy on system-level design, adapting existing technologies to the local climate, and integration of high quality, cost effective components from around the world to form the core renewable energy storage solution that we offer. We do not design or manufacture components.

5. We are committed to local ownership and community control of energy generating assets. We require majority (51%) control of all renewable energy storage and generation infrastructure we help build, by permanent residents of the state, territory or province. Indigenous governments must approve projects within their traditional territory and are expected to be the major stakeholder.
