Kardinia Energy is a manufacturer and supplier of printed solar modules that use carbon-based semi-conducting polymers printed on recyclable PET plastic (materials that are highly abundant and do not require the energy-intensive manufacturing processes associated with silicon solar panel production). The printed solar modules weigh 300g per square meter and utilise easily sourced, non-silicon-based materials. This enables localised manufacturing that bypasses traditional supply chains and the economic constraints imposed by conventional photovoltaic modules.

EnyGy has invented a line of higher performance ultracapacitors, an energy storage device that rests somewhere between a conventional capacitor and a battery. The company makes its ultracapacitors by melding activated carbon electrodes with a state-of-the-art electrolyte and claims this boosts energy densities up to double the capacity of alternatives, while remaining cost-effective.

Hysata develops ultra-high-efficiency hydrogen electrolyzers that intend to achieve the lowest cost of hydrogen. Thanks to high efficiency in an inherently simpler, cheaper and modular system (according to the company) its electrolyzer achieves 95% efficiency, significantly exceeding the International Renewable Energy Agency's 2050 efficiency target. Hysata's electrolyzer design is based on two key innovations: an ultra-low-resistance separator and bubble-free operation. Together, these factors reduce cell resistance and make the cell highly efficient. With the support of leading global strategic and financial investors, Hysata is rapidly moving toward multi-gigawatt production.
