California greener with electricity and hydrogen

California greener with electricity and hydrogen. From next June all new buildings will have to have electric cookers. LPG or methane, in fact, are the second cause of greenhouse gas emissions in the Californian city. California, in addition to photovoltaics, wind and hydro, is focusing on hydrogen.

Many hydrogen-powered buses are in service in the main cities of the state, while the number of fueling stations with zero environmental impact are multiplying, like in San Francisco and in San Diego. Hydrogen could provide America with 14% of its total electricity needs.

California Energy Commission will spend on hydrogen projects by the end of 2023. The vehicles currently in circulation and powered by hydrogen are also a negligible number compared to the fleet of petrol and diesel cars but the state program provides to reach over 50,000 vehicles by 2030 and over a thousand refueling stations.

The cost of guaranteeing the presence of the latter on a vast territory.

As is well known, hydrogen vehicles emit only water vapor, bringing to zero the greenhouse gas emissions that are so worrying not only California but the entire globe at this time.

Certainly, however, these vehicles will not be the immediate solution to pollution, both for the costs of hydrogen production and for the difficulties of creating a capillary distribution network that makes the transport of people and things convenient, even over long distances.

distances. The intention of the Californian authorities is to create a virtuous network for travel on cars and trucks based on the use of energy drawn from renewable sources, such as hydrogen, but also lithium-ion batteries supplied by photovoltaic panels or from wind turbines.

the main problem with hydrogen is the poor distribution of refueling points, which leads motorists who have bought vehicles with this fuel to long lines in the few available distributors. The problem remains that of the production costs of hydrogen fuel cell vehicles.

The difference is almost double the amount needed to buy an electric car. The difficulty of refueling without having to travel many kilometers to reach a refueling station is another problem. The difference, however, is ultimately given by the waiting times for the actual refueling.

Electric cars require from 45 minutes to several hours to fully recharge and their range, at the moment, does not exceed 400-500 kilometers. The hydrogen car, on the other hand, fills up in a matter of minutes and has a longer range than cars with lithium-ion batteries.
