Existing fossil gas infrastructure such as pipelines and appliances are “mostly unusable” with hydrogen, without either major investment, or changes in operation that would significantly reduce the amount of energy delivered to customers, a new peer-reviewed study has revealed.

The paper, A review of challenges with using the natural gas system for hydrogen, published yesterday (Monday) in the Energy Science and Engineering journal, examined the risks and potential solutions for the use of hydrogen in existing long-distance and distribution pipelines, storage and end-use appliances — as well as re-iterating the risks of explosions, fires and asphyxiation caused by hydrogen leaking from poorly adapted infrastructure.

Abstract

Hydrogen, as an energy carrier, is attractive to many stakeholders based on the assumption that the extensive global network of natural gas infrastructure can be repurposed to transport hydrogen as part of a zero-carbon energy future. Therefore, utility companies and governments are rapidly advancing efforts to pilot blending low-carbon hydrogen into existing natural gas systems, many with the goal of eventually shifting to pure hydrogen. However, hydrogen has fundamentally different physical and chemical properties to natural gas, with major consequences for safety, energy supply, climate, and cost. We evaluate the suitability of using existing natural gas infrastructure for distribution of hydrogen. We summarize differences between hydrogen and natural gas, assess the latest science and engineering of each component of the natural gas value chain for hydrogen distribution, and discuss proposed solutions for building an effective hydrogen value chain. We find that every value chain component is challenged by reuse. Hydrogen blending can circumvent many challenges but offers only a small reduction in greenhouse gas emissions due to hydrogen’s low volumetric energy density. Furthermore, a transition to pure hydrogen is not possible without significant retrofits and replacements. Even if technical and economic barriers are overcome, serious safety and environmental risks remain.

Dumping The ‘Clean’ Energy Mess Right In Your Backyard

The anything inevitable about the so-called wind and solar transition is that people inevitably conclude the whole thing is an environmental and economic fraud.

There’s nothing ‘clean’, ‘green’ or even vaguely ‘renewable’ about solar panels and wind turbines. Which are utterly pointless, because they can’t deliver power as and when we need it.

Solar panel are a veritable cocktail toxic gunk, so are wind turbine blades – which are all headed for landfill, where they will leach their poisonous entrails into the atmosphere and water tables for centuries to come.

In the piece below, Kristen Walker is one who is finally coming to grips with the fact that she and all of her fellow environmentalists have been lied to, for years.

Coming Clean on Clean Energy: It’s a Dirty Business
Watts Up With That?
Kristen Walker

Unless you’ve been living under a rock, you are probably aware of the massive push to transition to green energy. The goal is to have wind and solar replace coal and natural gas; the electric vehicle (EV) will supposedly replace internal combustion engines. Directives are coming from the highest office in the land; the current administration has made green energy a large part of its agenda.

We are being told that these technologies are clean and will save the planet from climate change. However, these alternative forms of energy being espoused are riddled with their own problems.

Hidden behind the solar panels, wind turbines, and EV batteries are some dirty secrets that get swept under the rug and ignored by climate enthusiasts.

Fossil fuels are constantly put under a microscope and condemned as an evil destructive polluter; green energy is typically put on a pedestal. Green energy, however, is not as perfect and wonderful as we are made to believe. Yet, we are putting a lot of trust into these energy sources, without considering their ramifications.

The American Consumer Institute just released a report detailing many of the environmental impacts associated with the so-called green energy forms being heavily promoted. The life cycle of all three—the wind turbine, solar panel, and EV battery—involve significant environmental consequences that should not be overlooked and need to be part of the discussion when implementing energy policies.

One of the biggest issues involved with these forms is the extraction and manufacturing processes of various critical minerals that are required for wind turbines, solar panels, and EV batteries. Many underdeveloped nations, where there’s an abundance of minerals, are at risk. The operations and procedures not only overtake land but contaminate surrounding soil and water sources. In the worst cases, this work is accomplished through slave labor.

Various toxins and other greenhouse gases are released into the atmosphere, where workers and even nearby communities are potentially affected. Landscape is tarnished and various animal habitats are shrinking and/or experiencing stress. The massive amount of land occupied by both wind and solar may never be recoverable.

China dominates the green energy supply chains, but their environmental standards are subpar. CO2 emissions associated with refineries in China are 1.5 times greater than those in the EU or U.S.

All three energy sources are also creating a huge waste problem. Since any kind of recycling is very limited on a large scale, more than 90% wind turbine blades, solar panels, and EV batteries end up in landfills. By 2050 it is predicted that used turbine blades will exceed 43 million tons of waste worldwide. Solar waste is predicted to be close to 80 million tons. And with the U.S. projecting 33 million EVs on the road by 2030, that is a lot of batteries to end up in landfills.

Ironically, the same folks who want to charge customers for every plastic bag they use at the grocery store, out of fear of single-use plastics ending up in landfills, don’t seem to have a problem with potentially toxic machinery filling that space instead.

In a penchant for trying to solve one crisis, we are creating others.

Some of the environmental impacts and hazards posed by green energy are far more detrimental than fossil fuels, and yet the latter is often dismissed. Such risks associated with green technologies should actually be an argument against vigorous pursuit of them.

It is past time to come clean on so-called clean energy. The real-life consequences and detrimental effects of it demand more honest conversations and a thoughtful course of action.

LEADING ATMOSPHERIC SCIENTIST, RICHARD LINDZEN, SUMMARISES THE DEBATE ON GW

Richard Lindzen is not a household name ,like David Attenborough,  but that does not mean he is not a great scientist. On the contrary, his achievements are outstanding, (see his Wikipedia entry here: Richard Lindzen – Wikipedia ) He is someone who should not be ignored, as he has spent decades studying the physics of the atmosphere. His latest speech gives a good analysis of the state of climate science at the link below:

 “Those who can make you believe absurdities, can make you commit atrocities” – Clintel

The following section provides a neat summary of where we are today:

So here we are, confronted with policies that destroy western economies, impoverish the working middle class, condemn billions of the world’s poorest to continued poverty and increased starvation, leave our children despairing over the alleged absence of a future, and will enrich the enemies of the West who are enjoying the spectacle of our suicide march, a march that the energy sector cowardly accepts, being too lazy to exert the modest effort needed to check what is being claimed.
