Earthshot
Plan launched June 2021
Hydrogen shot 111
Reduce hydrogen costs 80% to $1 per 1 kilo in 1 decade by improving performance, cost, durability of electrolyzer systems
Hydrogen shot impact
5fold increase in hydrogen use will reduce carbon dioxide emissions 16% by 2050
14 bil revenues, 700k jobs by 2030

Asphyxiant gas
Non toxic gas that reduces or displaces oxygen concentration in air, potentially leading to asphyxiation
Combustion factors
Ignition spark, oxygen, fuel
If these 3 are present, there is risk of combustion
Hydrogen ignition risk
Ignites more easily than gasoline or natural gas
Needs better ventilation and leak detection
Hydrogen
Energy carrier that can be used to store, move, deliver energy from other sources
Can be produced by electrolysis, natural gas reforming, solar, etc
Fuel cells in US
In 2021, 166 fuel cell generators at 113 facilities in US, capacity to producing 260 megawatts of electricity. Largest in CT with 16 MW capacity. Next largest is 6 MW capacity
Fuel cell efficiency
Can be 2-3 times more efficient than combustion engine on gasoline
