What do we do?


Make Clean


Hiringa Energy is developing hydrogen production projects using electrolysis.

new renewable electricity 

generation for green hydrogen that can displace the use of fossil fuels for transport and industrial feedstock.

  • Environmental sustainability and economic growth are not mutually exclusive.

  • Hydrogen is a key piece of the puzzle for addressing climate change.

We want to:

  • Create opportunities and wealth for New Zealanders.

  • Create long term competitive advantage for NZ businesses based on low emission energy use.

  • Benefit our communities by creating more efficient, cleaner energy.

We will:

  • Deliver solutions that are operationally efficient, practical, sustainable and convenient.

Our Team

We work with you

The journey to zero emissions is no solo endeavour. It needs to be one of business, 

local authorities, government, and communities all working together.

That's why most of our projects are joint ventures - partnerships between us and other organisations. We are building partnerships with progressive organisations seeking economic, zero emission solutions. 

So let's talk about how, together, we can make hydrogen work for you.
