Our Principles

Clean energy for all

Hydrogen is the new frontier and we have the power to change the global energy landscape forever. We honor this responsibility and work towards building clean energy systems that are accessible to all, leaving no communities behind.

Energy sovereignty

Decentralization and access are the keys to energy sovereignty. But you can’t empower yourself with something you don’t know or understand. Knowledge is power and along with building cost-effective systems, we educate people on the importance of clean hydrogen.

Real climate solutions

We aim to create hydrogen systems that are zero-emission and reduce the impact of climate change today. We are intentional about every aspect of climate and social care on all of our system designs

Respect and gratitude

We make a commitment to foster an environment of trust, transparency, mutual respect, and gratitude; in our workplace, with our partners, and in the community. Ethical business practices are ingrained in our values and we prioritize employee success, safety, and fulfillment.
