Hi Shashi, To make an impact on Net Zero by 2050 requires a scale of operation that probably replicates the Oil & Gas industry investment to date. Clearly the XPRIZE PURSE will be totally unable to support such a level of investment across all suppliers of components that will meet the areas of Hydrogen, including Production and storage Cylinders, Fuel cells for deliveries of electricity, Residential systems together with local electricity storage panels, Forecourt gas and electricity energy delivery systems, ship loading, transportation of compressed gas plus decompression on arrival port. Then there is EV hydrogen and electrical propulsion systems and Industrial energy systems. The list of new and expansion of existing industries is extensive and the above is just part of what will be needed. I recently heard a VP of Shell Petroleum inform an audience that it will cost around $15 Trillion a year investment between now and 2050, so even a $20 Million XPRIZE is a drop in the ocean. Maybe five Billionaires can be persuaded to each invest $1 Billion to kick-start the necessary changes required to improve the air quality of our planet… but I doubt they would do so… Climate Change will propel the Fifth global industrial revolution. The current XPrize company submissions are probably all going to be needed to meet the objective of net zero, so a grand centre showcasing all their products, systems and skills could become the go-to magnet for all countries interested in signing to meet Net Zero by 2050 pledge.
