ZeroAvia is a developer of zero-emission powertrain for commercial air travel.  In September they made their first test flight in Cranfield in the UK using a 6-seater hydrogen-fueled aircraft for taxiing, taking off, circling and landing.  ZeroAvia’s first commercial product will be the powertrain for 20-seater planes and aims to demonstrate that it can fly a plane over 800km with as many as 20 seats by 2023. They want to scale up to 1,600km with over 100 seats by 2030.   Aviation is a challenging industry to decarbonise and will increasingly contribute to unwanted carbon emissions.

Think about the warm water in your shower, dishwasher, washing machine and more. All that heat is wasted as it goes down your drain. It is even worse in hotels or industrial applications like dairies, food manufacturing and breweries. So why not intercept the warm/hot water as it exits the building and before it goes into the sewers? Via a holding tank with a heat pump, you can then extract the heat and re-direct it to where it is needed rather than wasting it - saving money and GHGs .
