Running simulations at NERSC, the research collaboration found that the effect of climate change on future storms in the San Francisco Bay Area will be significant, leading to more powerful storms unleashing substantially more water.

Hydrogen Fuel Cell Electric Vehicles: How they Work Hydrogen fuel cell electric vehicles (FCEVs) are similar to electric vehicles in that they use an electric motor instead of an internal combustion engine to power the wheels. However, while electric vehicles run on batteries that must be plugged in to recharge, FCEVs generate their electricity onboard. In a fuel cell, hydrogen gas from the vehicle’s fuel tank combines with oxygen from the air to generate electricity with only water and heat as byproducts of the process. Fueling a hydrogen FCEV is similar to refilling a vehicle’s gas tank, but using a nozzle from a designated hydrogen dispenser at a public station. Refueling times are also similar: FCEVs can be refueled in as little as 5 minutes. Some FCEVs can go more than 300 miles on one tank of hydrogen fuel — greater than the distance from St. Louis to Chicago — and fuel economy close to 70 MPGe (miles per gasoline gallon equivalent).
