Green Hydrogen

Green Hydrogen may help the world get to a fully decarbonized energy sector. Hydrogen is an energy carrier and key chemical in processes. Today the world uses between 120-140 million tons a year, almost all of it made from coal or natural gas, leading to large GHG emissions. There are a rainbow of colors of hydrogen including:

  • grey (made with natural gas)
  • blue (using carbon capture)
  • pink (made with nuclear)
  • green (made with water and renewable energy)

More than 40 Gigawatts of new hydrogen production have been announced in the last 2 years with Australia leading the way.

Hydrogen is storage, a fuel, a key component of fertilizer and a feedstock for many processes. In short it is potentially one of the most flexible ways to store excess (or even dedicated) renewable energy. Issues remain in storage, round trip efficiency, and conversion of existing infrastructure to use hydrogen, which creates opportunities for IEEE members.

To help our members keep up with the latest developments in the emerging area of grid resilience, IEEE Power & Energy Society has created a number of resources on hydrogen. Below, we highlight a few notable contributions.

In this edition there are 3 articles on Hydrogen which are good introductions to what is happening and some of the issues:

Green Hydrogen: Challenges for Commercialization

Written by Sivapriya Bhagavathy and Jagruti Thakur

Hydrogen has been in use for many decades in sectors like refining and chemical industries. However, its use as an energy source has started receiving increased interest only in recent years. As this interest and end-use grow, the demand for hydrogen will also grow with an expected compound annual growth rate of 5.48% from 2019 to 2025 [1].

Green Hydrogen and Transportation Industry – An Overview of Its Applications

Written by Vishalya Sooriarachchi

Green hydrogen, a major part of the transformation towards 100% renewable energy, is considered an important source of energy. It currently is of considerable cost as of now, and only comprises a minimal amount of energy percentage in the U.S. energy market. However, there is higher interest in determining the level of significance green hydrogen is capable to play in the development of the transportation industry considering a revolutionary development is needed in the sector. The usage of Green Hydrogen in the transportation sector has created a novel requirement to initiate the development of cost-efficient extraction methods and the share of renewable sources rendered for the production of Hydrogen is expected to increase in order to comply with a considerable percentage of energy demand in the transportation sector.

Using Curtailed Renewable Energy to Produce Green Hydrogen

Written by Doug Houseman

In 2020 California curtailed more than 1.3 Tera-watthours (TWH)1 up from 1 TWH in 20192. Curtailment is rising faster than installation of new renewables and will continue to grow until storage catches up with renewable production.

Here is an article on hydrogen for vehicles and why hydrogen might be a better choice.

The automotive future belongs to fuel cells range, adaptability, and refueling time will ultimately put hydrogen fuel cells ahead of batteries

Microgrids might be a good place to use hydrogen as well, as discussed in this technical paper:

Optimal Load Sharing of Hydrogen-Based Microgrids With Hybrid Storage Using Model-Predictive Control
Authored by F. Garcia-Torres; L. Valverde; C. Bordons

 

And another good look at Microgrids and hydrogen

Coordinated Control Strategies for Fuel Cell Power Plant in a Microgrid
Written by L. Sun; G. Wu; Y. Xue; J. Shen; D. Li; K. Y. Lee

 

Green Hydrogen can be made from more than just water and electricity as is discussed in the following paper:
