Hydrogen economy refers to the use of hydrogen as a primary driver for the production and consumption of goods, services, and the supply of money. Hydrogen can be used as a low-carbon fuel for heating purposes, transport, energy storage, and long-distance transport of energy.
In 1900, conventional cars were developed but there was no infrastructure for gasoline. Yet the conventional car became successful due to improving transport efficiency, which resulted in economic growth, and the infrastructure was then developed to meet such demand.
Let’s look into some facts about hydrogen.
How Hydrogen is produced?
Hydrogen is abundantly available in the Universe. Hydrogen can be produced through steam reformation technology, gasification of coal, Natural gas or from the electrolysis of water.
Currently, 75% of H2 is produced from Natural gas, 23% from coal, and the remainder from Biomass and electricity accounts. Challenge is to produce hydrogen economically.
How Hydrogen can be transported?
Hydrogen is not an energy, but an energy carrier, which means its role is a lot like electricity. Because of its molecular structure, hydrogen can be combined with carbon and nitrogen to make hydrogen-based products that are easier to handle and are used as feedstock to reduce emissions. Hydrogen-based fuels and feedstocks can be produced from any source of hydrogen, whether electricity, Biomass or fossil fuel. Ammonia is like chemical feedstock or can be used as a fuel, which is made of hydrogen with nitrogen.
How is Hydrogen compared to Natural Gas?
Energy per unit mass is 3 times of gasoline, energy density is 1/3rd of natural gas, gas density is 1/10th of natural gas, the boiling temperature is 90 Deg below LNG, flame velocity is 8 times of methane, and ignition range is 6 times wider than methane.
Why is Hydrogen gaining popularity now?
Reducing the cost of batteries and growing renewable penetrations offers opportunities to store excess renewable energy in the form of Hydrogen or in batteries and use it whenever required.
In future, Hydrogen and electricity produced thru renewable energy sources has a close association. This close working is needed to avoid energy wastage, improve system efficiency, and for sustainable economic growth without impacting planet earth.
Impact on Economic Growth:
A case study on Japan's economic growth with Hydrogen impact is being studied by IEEJ. The report is derived based on 70% CO2 constraint by the Year 2050 with the Year 1990 as reference. The GDP by the year 2050 is likely to increase by 4.2% with Hydrogen injection as against no constraint case. Fossil fuel and hydrogen spending will increase by 16% but the average energy price will fall by 26% although the primary energy supply will increase by 11.4%. Power generation capacity will be expanded by 9.3% and all this is possible by inducing 23 Mtoe of Hydrogen.
So the future is green with a far reduced impact on our dear plant yet with a positive impact on economic growth.
