The off-grid energy and long-haul transport sectors, unregulated until the last decade, must be net zero by 2050. Battery technology is unsuitable due to cost and weight. Hydrogen technology is considered to be the only viable solution to decarbonising these sectors. Carnot power units will have greater efficiency, lower total cost of ownership and greater range, reliability and durability than fuel cells. They are the key to unlocking a hydrogen future while minimising the impact to supply chains.
Modern Internal Combustion Engines typically waste a third of fuel energy to cooling systems, which prevent metal components from melting, and therefore have efficiencies of only 35%. Carnot power units are designed with key components manufactured from advanced ceramics which can withstand these high temperatures. This eliminates the need for a cooling system and results in half the fuel use. With efficiencies of 70%, clean Carnot power units are the best solution to unlocking a net zero hydrogen future for large/long-haul applications.
Carnot and Net Zero
Carnot power units will be developed to run on hydrogen and biofuels for net zero operation. They will also enable intermittent renewable energy technologies such as solar, wind and hydro-electric power by providing clean backup power and long-term, bulk energy storage for seasonal variations in supply. In order to facilitate the transition to zero emissions, Carnot power units will also operate on hydrocarbon fuels, halving emissions.
Operating on hydrogen, Carnot power units will produce water as the combustion product. They wil have higher efficiency, lower total cost of ownership, greater range and durability and reduced weight compared to hydrogen fuel cells.
Carnot power units will run on biofuels for net zero carbon operation. Biofuels can be produced from energy crops or simply from the vasts amounts of organic/agricultural waste produced around the world.
Enabling Renewable Energy
Carnot power units will be integrated into renewable energy grids to provide clean backup power during periods of low supply. Guaranteeing continuity of supply is critical to enabling mass adoption of renewable energy technologies globally.
Hydrogen is produced in an electrolyser and stored during periods of surplus renewable energy. This will then be used in a high-efficiency, clean Carnot power unit to generate electricity during periods of low supply. Unlike battery technology, this is ideal for long-term, bulk energy storage to balance seasonal variations in supply and demand.
