Optimal Renewable Gas is a part of the Optimal Group, dedicated to solving challenges for energy users. Optimal Renewable Gas was founded to deliver renewable gas to grid, and renewable gas to LNG and CNG solutions for commercial and industrial energy users looking to meet their net zero objectives. Recognising that renewable gas is a critical link in enabling industry, which are often dependent on thermal processes including hot water, steam or drying for up to 70% of their total energy needs. Optimal Renewable Gas is building multiple grid scale organic waste to gas anaerobic digestion systems across Australia, which includes gas clean-up and compression systems. Biogas, a mix of carbon dioxide and methane, is purified into biomethane, and then compressed before being injected into the gas network, alternatively optimal will also develop application where the gas is trucked as compressed natural gas (CNG) or liquefied into liquid natural gas (LNG).
