Presently, we offer solutions pertaining to renewable gases including Syngas, Biomethane (and Biogas) and Green Hydrogen. These solutions are realized through advanced technologies such as the RBE ECHO2 and Panasonic Fuel Cells and sometimes in collaboration with our affiliate company, Optimal Renewable Gas.
Renewable Gas
Optimal Group provides an extensive array of solutions pertaining to renewable gases, which are gases capable of serving as sustainable energy sources, yielding zero net carbon emissions upon combustion. These gases can be efficiently stored in substantial quantities within established distribution networks.
Biomethane & Biogas
Commonly referred to as renewable natural gas, biomethane serves as an eco-friendly alternative to traditional fossil fuel-based natural gas. It results from the refinement and purification of biogas, which is generated through the anaerobic digestion or gasification of organic matter, including agricultural residue, municipal solid waste, plant material, and sewage. Biomethane seamlessly integrates into the existing natural gas infrastructure, offering a direct substitute for fossil-based natural gas across various applications such as heating, culinary use, and electricity generation. The transition to biomethane is advantageous for environmental reasons as it captures methane, a potent greenhouse gas, which would otherwise be released into the atmosphere from organic waste streams. Optimal has vast experience when it comes to delivering biogas solutions, especially for customers with a suitable source of organic waste. Some notable examples of this include the work that we have done at Surbiton Park Recycled Water Plant and McCain Foods’ Ballarat manufacturing facility. Additionally, we have a sister company, Optimal Renewable Gas, which is actively engaged in the development of biomethane projects in Australia.
Green Hydrogen
Green hydrogen holds significant promise for nearly eradicating emissions by leveraging renewable energy sources, even during non-optimal periods, to facilitate water electrolysis. Our company specialises in the utilisation of green hydrogen, which can be incorporated into Panasonic Fuel Cells to generate power with exceptionally low level of greenhouse gas emissions. Furthermore, a testament to this is our involvement in Jemena’s Western Sydney Green Gas Project, which included the delivery of a Capstone microturbine operating exclusively on hydrogen, marking yet another pioneering achievement for Optimal Group on the global stage.
Syngas
Syngas, short for synthesis gas, constitutes the volatile gas fraction derived from pyrolysis. This gas is a renewable, combustible resource with the potential to serve as a substitute for or a means of reducing reliance on fossil fuels such as natural gas, diesel, and LPG. Its primary constituents encompass hydrogen, carbon monoxide, and carbon dioxide. In contrast to many prevailing pyrolysis technologies prevalent in today's market, which yield hot syngas alongside tar and various contaminants necessitating extensive purification procedures, the RBE ECHO2 system, offered and distributed by Optimal Group, generates pristine, cool, and high-quality syngas, with minimal post-processing requirements. This technology also stands as an economical and dependable source of renewable hydrogen.
