Our Customer Value Proposition is that we can deliver zero emission power systems at lower cost, whilst simultaneously offering better durability and operating efficiencies than other systems. This reduces both the CAPEX and OPEX costs of deployed systems.
Clean Power's patent protected architecture affords a number of compelling advantages over traditional PEM fuel cell systems.
Comparative cost analysis, on volume production numbers, conducted by E4Tech shows that our solution is between 33% to 50% cheaper than traditional PEM fuel cells.
Our novel system architecture has designed out almost all of the degradation mechanisms present in conventional PEM fuel cells. Durability studies using both stationary power and automotive drive cycles show almost no reduction in performance after 1,000s of hours of operation.
Our system replaces the slow cathode side chemical reactions with a "battery" like architecture meaning, our system can follow changes in electrical loads "near instantly". When used as part of an electric drive train, Clean Power's responsiveness to changing loads means the battery deployed for managing peak power demands can be smaller - saving additional cost, complexity and weight.
Unlike conventional PEM fuel cell stacks, Clean Power's systems do not deliver hydrogen and air directly to the fuel cell stack. The air circuit is separate - with the oxygen in the air being bound within the liquid catholyte in our system. Since there is no possibility of hydrogen/air gas mixing in the stack, Clean Power's design has enhanced safety.
Our systems are scalable, like other fuel cells where stacks can be ganged together to create larger systems. Clean Power's stacks are the same regardless of application as we do not load the cathode with additional platinum catalyst to improve durability in demanding applications. Our Balance of Plant scales with the power of the system, not to the number of stacks. This has significant positive effects on reliability and reducing parasitic loads associated with Clean Power's systems.
Clean Power's design removes up to 80% of the platinum catalyst used within conventional systems. Our platinum catalysts requirements are very modest and less than the platinum which can be recovered from recycling the retiring internal combustion fleets' catalytic converters. This foregoes the need to mine additional platinum and the associated negative environmental impacts. Clean Power's systems have been designed so many of its components can be recycled/reused. Clean Power has signed the Race to Zero pledge.
This represents a major advantage of the Clean Power technology: performance at low current density. By avoiding the direct reduction of Oxygen, which requires a large overpotential (~200mV). Our liquid catholyte reduction kinetics are much less demanding. Our test cells have achieved 708 mA/cm2 at 0.8V vs. the DOE 2020 target of 300 mA/cm2 for conventional fuel cells.
The technology is protected by a large number of patents which cover all aspects of the novel architecture and liquid catholyte. Patents have been awarded in all the major territories likely to result in large fuel cell markets - see yellow coloured countries above on the world map.
