Hydrogen: Key ingredient to achieve Net Zero.

With carbon emissions set record high, countries are setting up targets and working towards keeping the rise in temperature below 2 degree celsius to limit the rate of climate change as proposed in the Paris Agreement.

VREs (Variable Energy Sources) are playing a key role in advancing technologies for maximum capitalization of available resources to deploy in combating rise in temperature, one key ingredient being Hydrogen.

Hydrogen are of various types based: few of them being Grey, Blue, Turquoise and Green.

In summary, Grey hydrogen is produced from fossil fuels majorly Coal, Blue is generated via coal or methane but carbon capture technology is deployed. Turquoise is generated in a way where no emission can be observed however the most preferred is the Green Hydrogen which is produced from Renewable Energy Sources and hence is the strongest combat tool in this context for lowering the GHG emissions.

Capitalization of these types of hydrogen is essential, direct shift to green hydrogen will put a pressure on installation of REs, hence a model should be proposed with a tight timeline of phasing hydrogen one by one leading to Green Hydrogen
