The Truth Behind The Hydrogen Hype

Is hydrogen really a zero carbon fuel that we dream of?

The Truth Behind The Hydrogen Hype

Hydrogen is being touted as the fuel of the future, but new information suggests hydrogen could have serious implications for the climate. 

By D.S. Mitchell

Maybe Not The Golden Ticket

As the hydrogen hype machine revs up to a roar, investigators are discovering potential, undisclosed  hazards to the climate. Scientists are warning that hydrogen is not the golden ticket to stabilize the earth’s climate that supporters claim. One big problem is that hydrogen leaks and those leaks are harmful to the environment.

EDF’s Solutions Magazine Vol.54 No.2/Spring 2023

Hydrogen’s promise as a climate solution has fascinated Hollywood screenwriters, entrepreneurs, scientists, and governments, including China, India, the U.S. and EU for decades. According to McKinsey  & Co. investment in hydrogen manufacture is coming fast and furious as governments and individuals embrace hydrogen. Over the next decade 680  large scale hydrogen projects will be commenced worldwide at a projected cost of $240 billion.

Zero Carbon? Yes and No.

When hydrogen is burned or used in a fuel cell it produces zero carbon emissions. Wha-hoo, that fact is why hydrogen has become the holy grail of climate friendly energy. But as with all things, not so fast. Pure hydrogen is rarely found in nature. Because of that, hydrogen must be EXTRACTED from another source. Today nearly all hydrogen is extracted from coal and natural gas and that process releases carbon dioxide into the environment. Damn, that doesn’t sound good and it isn’t good. Investigators claim if “hydrogen production were a country it would rank as the world’s fourth largest source of carbon dioxide.” Staggering numbers when the small amount of hydrogen being produced is taken into consideration.

Green Hydrogen

Green hydrogen can be produced from water, using renewable energy. Unfortunately, less than 1% of hydrogen production is green. But, even green hydrogen isn’t harmless. When burned hydrogen creates nitrous oxides. Those pollutants can cause asthma, bronchitis, and heart disease. Furthermore,  hydrogen is leak prone with a potent climate warming effect that is not talked about, but needs to be addressed. As  EDF scientist, Ilissa Ocko said, “If hydrogen is going to deliver what its backers promise, we need to keep it from escaping (leaking) into the atmosphere.”

A Fully Hydrogen Powered World is Unlikely

Currently, hydrogen is used primarily in oil refining and the chemical industry. Otherwise, hydrogen use is on a very small scale in buses, cars, trucks, trains, and homes.  Ocko believes a fully hydrogen powered world is “unlikely and unnecessary.” In most cases renewable electricity is a more efficient choice. If hydrogen isn’t going to be universal where does its production make the most sense? The experts say it makes the most sense in heat-intensive industries, such as cement production, or in ships where electrification is difficult.

Keep ‘Em Close

Scientists are recommending the manufacture of hydrogen be close to where it will be used. It is important to minimize leaks during transportation. Experts agree that a hydrogen system that’s as leaky as the current natural gas system could lead to major problems for the environment and the climate. Locating, measuring, and sealing hydrogen leaks is a critical issue that will need to be solved.

How Dangerous Are Hydrogen Leaks

Hydrogen leaks are a safety hazard because hydrogen gas molecules are tiny and flammable.  Because hydrogen is an indirect greenhouse gas when it leaks it creates a chain of chemical reactions that raise levels of greenhouse gases in our atmosphere. Small hydrogen leaks are serious because they exacerbate global warming. Finding those small leaks, until recently was impossible. Today however a new sensor is showing success. By detecting tens of parts per billion of hydrogen within seconds, the sensor represents a technological breakthrough in hydrogen emissions detection. Tianyl Sun, an EDF scientist says, “right now we know very, very little about how much hydrogen leaks. Filling that gap in our understanding is critically important for the climate.”

The Future of Hydrogen

The future of hydrogen is up in the air. Hydrogen can be a key tool to cut climate pollution, but its dangers may outweigh its positives. As with most things, time will tell.

Carbon Capture Is B.S.

Carbon Capture Is B.S.

“Carbon capture and storage is a process in which a relatively pure stream of carbon dioxide from industrial sources is separated, treated and transported to a long-term storage location. For example, the carbon dioxide stream that is to be captured can result from burning fossil fuels or biomass.” Wikipedia

 

CARBON CAPTURE IS DANGEROUS BULL SHIT

By D. S. Mitchell

Oil companies are woke to the fact that carbon capture allows them to remain in business longer. I’m  sure there are CEO’s at the big oil companies who believe that all they have to do is bury their emissions and they can stay in business forever. CO2 is their industry waste, in other words, their damn garbage. It is the biggest driver of climate crisis and the greatest threat to our food and water supply. Carbon capture is a scheme of the fossil fuel industry that has found supporters in Washington, D. C.

The U.S. government, actually the U.S. taxpayer, is offering big bucks to companies working on carbon capture projects. The most conclusive thing we know so far about carbon capture is that it is a failure; a dangerous failure.  The dream of carbon capture “keeps the U.S. addicted to fossil fuels, degrades our agricultural land, threatens our water, and puts our communities and climate at risk.” Emma Schmit.

Summit Carbon Solutions, Navigator Heartland Greenway and Wolf Carbon are proposing nearly 4,000 miles of hazardous pipeline that will cross Iowa, Illinois, Minnesota, Nebraska, South Dakota and North Dakota. Hopefully activists in those states will pressure state authorities to deny permits to applicants for these dangerous projects. In many cases these pipelines are seeking eminent domain to force landowners to deed them private property for the pipeline.

The question really is why when we know the safety concerns and the technology is a failure, why is our government still trying to make carbon capture happen? It is time to stop the scam. Time to stop the fossil fuel industry from playing games with our future.

5 Reasons Carbon Capture is Dangerous Bull Shit

  1. Carbon Storage And Transport Are Not Safe. When carbon pipelines rupture they can expel lethal levels of carbon dioxide, an invisible asphyxiant literally for miles surrounding the break. CO2 displaces oxygen, stalling combustion engines and impairing emergency response. CO2 can leak from storage containers and contaminate groundwater and soil.
  2. Carbon Capture A Colossal Failure. Billions of public and private monies have been spent over multiple decades developing carbon capture projects and it has proven a complete folly. The Densbury Pipeline outside Satartia, Mississippi and the Petra Nova coal plant in Texas are just two examples of leaks, ruptures, frequent shut offs and persistent technological problems.
  3.  Carbon Capture Is Energy Intensive. The United States emits approximately 5 billion tons of carbon into the atmosphere annually. To capture a mere 25% of that figure would require nearly the entire electrical output of the nation.
  4. Carbon Capture Increases Emissions.  Due to both the life cycle of fossil fuels and the huge amount of energy required to capture carbon such projects in the U.S. have emitted more CO2 than it ever removed.  95% of the captured carbon is currently being used to extract more oil in a practice known as ‘enhanced oil recovery.”
  5. Carbon Capture Diverts Investments From Renewable Energy. Time is of the essence. We need to move to renewable energy to stop the worst effects of climate change, the greatest threat to our water, food, and a livable future. The switch from fossil to renewable sources will be slowed as long as the fossil fuel industry can convince the public and government officials to continue investing in carbon capture schemes instead of focusing on safe and proven clean energy solutions.

If you have little knowledge about the subject of carbon capture, now is the time to learn about it. Then once you understand the dangers please tell your Senator and your Congressperson that you want to stop wasting time and money on this bogus plan by the fossil fuel industry to stay in business forever.

ENERGY SAVING TIPS THAT COST NOTHING

By D. S. Mitchell

My PUD

I was on my local PUD (Public Utility District) website to make my monthly electric service payment, when for the first time I noticed they had a tab for Energy Saving Tips. Whoopee! So, without hesitation I opened the tab and found a treasure trove of no cost to moderate cost energy-saving tips. I was so impressed I printed it off for later reference. Hopefully you will find it helpful and will share all your new knowledge with friends and family.

No Cost Options

Saving money and addressing environmental issues are both good things.  Some of the tips may be familiar and obvious while others are not. Take a look and see if you can’t find something that will help you save energy and benefit the environment. An energy-efficient home will be a pleasure to come home to while saving you money.

Jump Start Energy Saving Now

  • Lower your thermostat when you go to bed or when you are away from home. Use a programmable thermostat, so it is automatic. Every degree lowered can decrease the heating portion of your energy bill by 2%.
  • Get in the habit of shutting off lights as you leave a room. Don’t forget to shut of PC’s and other devices when not in use.
  • Close your fireplace damper when there is no fire. Leaving it open is like having a 48 inch square hole in your house.
  • Set your water heater to 120 degrees F. (which is comfortable for most people). When going away for any length of time set it to vacation mode, or simply turn it down.
  • When washing cloths or dishes, wash only full loads and those in cold water.
  • Air-dry your dishes or use air-dry feature on the dishwasher. When weather permits, hang your clothes outside on a clothesline to dry.
  • Use kitchen and bathroom fans to cut moisture, as needed.
  • Set your refrigerator between 36-39 degrees F.
  • In the winter, open south-facing drapes/blinds during the day to let heat in and close all window drapes and blinds at night.
  • Unplug laptop or cell phone battery chargers when not in use. Most draw power continuously, even when there are no devices plugged into the charger.
  • Vacuum refrigerator coils of lint and clean the lint from clothes dryer often to increase efficiency.
  • Use a toaster over or microwave for cooking and heating small portions.
  • Use zonal-heat (baseboard, ceiling or wall heat) to your advantage by only heating rooms that are in use.
  • Consider using jugs of water to occupy the space in your refrigerator. It takes more energy to cool an empty fridge than a full one.
