Hydrogen can be utilised at utility scale power generation in different ways, depending on the specific technology employed.
Here are a few examples:
Clean hydrogen is a clean fuel as it produces no greenhouse gas emissions when used, and its combustion only produces water vapour. It does not contribute to greenhouse gas emissions, making it an attractive option for reducing carbon emissions.
Hydrogen can be used in a wide range of applications, including transportation, power generation, heating, and industrial processes. It can power fuel cell vehicles, provide electricity and heat for residential and commercial buildings, and be used as a feedstock in various industrial sectors.
Hydrogen can facilitate the integration of renewable energy sources into the energy system. By using surplus renewable electricity to produce hydrogen, excess energy can be stored and utilised during periods of low renewable energy availability. This helps to address the challenge of intermittency and variability associated with renewables.
Hydrogen is the most abundant element in the universe. While it is primarily found in compounds such as water or hydrocarbons, it can be extracted through various processes, including electrolysis or reforming of natural gas.
The challenges associated with hydrogen as a fuel include the cost of production of hydrogen using renewable energy, storage and transportation infrastructure, cost-effectiveness, and ensuring safety in handling and storage.
The waste products of hydrogen energy depend on the method of its production and utilisation. Here are the common waste products associated with different aspects of hydrogen energy.
