EcoJustice Radio, Ashley kosakIs Hydrogen the Clean Fuel of the Future? With Ashley Kosak from FracTracker Alliance

The fossil fuel industry has been promoting hydrogen as a reliable, low carbon, next-generation fuel to power cars, heat homes, and generate electricity. However, currently 99% of the annual supply of hydrogen comes from fracked methane gas. So will switching to hydrogen only lock us into continued fossil fuel use and additional investments in fossil fuel infrastructure?

The Truth About Hydrogen: Green Fuel or Greenwash? EcoJustice Radio

Proponents argue that when hydrogen is made using renewable power it can cut climate-warming industrial carbon pollution from the steel, oil, and agricultural industries. However, does hydrogen measure up when compared to powering our cars and homes with alternative renewable energy generated directly from wind and solar? Well, Ashley goes in depth. The following points summarize what is wrong with hydrogen as a carbon free energy source.

From Renewable Energy World: The top five fossil fuel industry myths that have been used to greenwash irresponsible hydrogen projects include:

Myth No. 1 – Hydrogen is emissions free: While hydrogen does not produce carbon dioxide (CO2) when combusted, it does produce high amounts of the air pollutant nitrogen oxide (NOx). In fact, hydrogen produces six times the amount of NOx as natural gas when combusted.

Myth No. 2 – Green hydrogen can help meet decarbonization goals: Green hydrogen is produced by using renewable energy to power a process called electrolysis. However, electrolysis is an extremely energy intensive process, and once green hydrogen is made, it must then be re-converted into electricity before it can be used. While there may be very specific uses for green hydrogen in hard-to-decarbonize sectors such as aviation, it is also a huge energy user undercutting renewable energy that could be going directly towards decarbonizing the grid.

Myth No. 3 – Hydrogen can be safely blended in existing pipelines: Even at very low levels of blending, hydrogen can crack steel pipelines through a process known as embrittlement, leading to explosions and high amounts of leakage.

Myth No. 4 – Hydrogen will save money: Hydrogen behaves very differently than natural gas. In addition to the pipeline issues mentioned above, most emissions control technologies in natural gas power plants are not equipped to handle large amounts of hydrogen. This means that beyond very low levels of blending, any pre-existing infrastructure will need to be retrofitted to safely use hydrogen, a very expensive endeavor.

Myth No. 5 – Hydrogen does not contribute to global warming: Hydrogen is an indirect greenhouse gas that extends the lifetime of methane in the atmosphere. Due to its small molecular size, hydrogen is extremely prone to leakage. A recent study found that based on current projections, global hydrogen leakage rates could be up by 6.5% by 2050 – producing the warming equivalent of 100 million to 200 million tons of CO2 in the atmosphere.

Our guest, Ashley Kosak, Research and Project Management Fellow with FracTracker Alliance, explains how hydrogen is generated, transported, stored, and burned; the environmental and social impacts; and what it means for the future of clean energy.
