Description
The Australian energy landscape is undergoing perhaps the biggest shift since electrification began over 140 years ago. An overwhelming and urgent shift to decarbonise the energy needed for businesses, homes, and transport systems requires a mix of solutions including renewable energy, energy efficiency and energy storage solutions, in order to meet climate goals for industry and government alike.
Optimal Group, an Australian-owned energy solutions business, is at the forefront of innovation and application in the energy sector and prides itself on “being in the problem-solving business” for our customers and partners. We offer a one-stop shop for our clients with services from feasibility, engineering to project delivery and lifetime service, support and monitoring.
We are a dynamic business who have delivered world-first technical solutions for urban and remote energy users across Australia and the South Pacific. Our team has pioneered and developed solutions in Capstone Microturbine combined heat and power, microgrids, ultracapacitor energy storage, gas microturbines & hydrogen fuel cells. We have active technologies in both CO2 capture and CO2 recovery for protected cropping fertigation.
Our business continues to expand into new and exciting areas of renewable energy through the development of biogas solutions, green hydrogen, and syngas from biomass to displace fossil fuels for power and thermal energy applications. Optimal Renewable Gas was formed in 2020 to develop grid-scale biomethane plants to produce and deliver renewable gas via the gas network and virtual network (rLNG & rCNG) pathways. Optimal Renewable Gas is targeting the delivery of over 10 biomethane plants by 2030.
Can you see yourself working with an organisation that values its people, leads the industry in delivering practical sustainable solutions, and is actively working on and developing new and innovative technologies?
If so, we would love to talk with you!
