Solar power can offer a superior alternative to nuclear fission for generating oxygen on the moon .This would require "six times less mass to produce the same amount of energy" as the best nuclear option, says the professor: https://interestingengineering.com/science/solar-power-generating-oxygen-moon

Heralds future of low carbon aviation, with the wider sustainable aviation fuel (SAF) industry potentially creating thousands of UK jobs while supporting delivery of net zero aviation emissions by 2050: https://www.gov.uk/government/news/worlds-first-net-zero-transatlantic-flight-to-fly-from-london-in-2023

The United Kingdom government has revealed that Virgin Atlantic will fly a historic net zero London-New York flight in 2023. Virgin Atlantic won a competition to receive government funding for the first net zero transatlantic flight. “For decades, flying from London to New York has symbolized aviation’s ability to connect people and drive international progress. It’s now going to be at the forefront of cutting carbon emissions from flying,” said British transport secretary Mark Harper. The development is a huge step forward for the airline industry's greener dreams.

Rolls-Royce Trent 1000 engines will power the airline's flagship Boeing 787s as it flies green. However, this will not be a typical commercial airline flight; rather, it will be the first passenger flight in the history of commercial aviation that uses only sustainable aviation fuel (SAF). This flight is anticipated to be powered by SAF, which is mostly made from used cooking oil and other waste oils and fats. Compared to conventional fossil jet fuel, SAF can reduce lifecycle carbon emissions by nearly 70% when entirely replacing aviation kerosene: https://www.cnn.com/travel/article/virgin-atlantic-net-zero-transatlantic-flight-saf/index.html
