How much hydrogen can be extracted from a litre of water?

Each litre produces 125 grams of hydrogen. So, to produce 1 kg of hydrogen requires 8 litres of water and 41.4 kWh/kg hydrogen.

How much water does a hydrogen fuel cell produce?

The modified fuel cells produced water at a peak rate of 1L/h with a quality close to that of distilled water.

How much water does it take to make a kg of hydrogen?

about 2.4 gallons
Based on the atomic properties of water, 1 kg of hydrogen gas requires about 2.4 gallons of water as feedstock. In one year, 60 billion kilograms of hydrogen would require 143 billion gallons of fresh, distilled water.

How can you increase the efficiency of a hydrogen fuel cell?

“We found that compression makes platinum much more active. We observed a 90 per cent enhancement in the ability of platinum to reduce oxygen in water. This could improve the efficiency of hydrogen fuel cells,” he said. The findings were published in the journal Science.

Can you drink the water from a hydrogen fuel cell?

Still, the company doesn’t recommend drinking it. That’s because the water is created by sucking in oxygen from the surrounding air and bonding it to hydrogen from the fuel tank. But the water is slightly acidic, with a pH around 5 or 6. That’s less acidic than acid rain and even beer.

How much electricity does it take to make 1 kg of hydrogen?

A 100\% efficient electrolyser requires 39 kWh of electricity to produce 1 kg of hydrogen. The devices today require as much as 48 kWh/kg.

How efficient is an electrolyzer?

Electrolyzer efficiency is the efficiency with which the electrolyzer converts electricity into hydrogen. So an electrolyzer that consumes 50 kWh of electricity to produce one kilogram of hydrogen has an efficiency of 39.4 kWh/kg divided by 50 kWh/kg, which is 79\%.

What happens when you mix water and gas together?

When the Two “Mix”. Due to the differing densities of water and gas, mixing cannot occur. As soon as you add water to a tank of gasoline, all of the water will settle to the bottom of the tank. The lighter gasoline will float on top.

How much Ca2+ and Mg2+ do we get from tap water?

For half of the tap water sources we examined, adults may fulfill between 8\% and 16\% of their Ca 2+ DRI and between 6\% and 31\% of their Mg 2+ DRI by drinking 2 liters per day. One liter of most moderate mineralization European bottled waters contained between 20\% and 58\% of the Ca 2+ DRI and between 16\% and 41\%…

What is the maximum amount of oxygen that can be delivered?

What is the maximum liters of oxygen? Standard oxygen sources can deliver from ½ liter per minute of O2 to 5 liters/minute (L/min). Every liter/minute of oxygen increases the percentage of O2 the patient breathes by 3 – 4 \%. Room air is 21\% O2.

What does 2 liters of oxygen mean on a concentrator?

What does liters of oxygen mean? Summary of Oxygen Concentrator Liter Flows. An oxygen flow rate of 2 LPM means the patient will have 2 liters of oxygen flowing into their nostrils over a period of 1 minute.
