Flying high on hydrogen
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.
Shower Power - harnessing the heat in your wastewater
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 .
Combining biogas & batteries
Batteries can provide high levels of power but only for a short period. Biogas plants are mechanically inert but can store en
