Engineering for sustainable future

I enjoy working in sustainable energy system design as a Principal Engineer in the Advanced Mechatronics group based in the Gracefield Innovation Quarter, Lower Hutt. Energy has always been important to me and my working life began working in civil nuclear power designing robot arms (manipulators) as an electronics engineer and system designer.

Nowadays, locally produced hydrogen from renewable electricity is a major focus of mine, supporting our HyLink System. This generates hydrogen from electricity produced by a renewable energy system. It is stored underground from where it can later be drawn for heating or cooking, providing safe, clean, and reliable power. We hosted a pōwhiri for distinguished International Energy Agency guests from the USA and Japan at which we used the HyLink System to power a barbeque that fed 50 guests.

I was delighted to join the Clean Technology team, led by Alister Gardiner, investigating local hydrogen generation and storage that led to HyLink. My work is directed towards enabling a cleaner, more sustainable world in which people have access to the energy they need for life.
