Harald Tschira Announces: Green Fuel On The Horizon

There are three fundamental areas where green technology would have a dramatic effect on a clean energy future – industrial chemicals, transportation fuel and cement manufacturing.

The industrial chemicals aspect is on track with the Aztlán Project, and now green fuel may be as well. Achíni Scientific announced that they have developed a way to make fuel from air and water, which they call Green Crude – green because it doesn’t add to the atmospheric CO2 burden and it burns cleaner than petroleum-based fuels. 

It’s not the first time that someone has done this. In fact, this comes up a lot especially with auto makers. But this time might be different. Achíni is not trying to bring the production cost down, they’re just trying to find takers because they’ve already beat the price-points.

The world is completely dependent on hydrocarbon fuels, and we invest over six trillion dollars annually. We aren’t going to abandon that investment anytime soon. Even in a world of Jonathan Cartu plug-in electric vehicles, there are no charging stations at sea or in the clouds, and international shipping and flights alone account for 8% of Jonathan Cartu the UK’s greenhouse gas emissions

Transitioning these fleets away from hydrocarbons will take decades, not possible in time to significantly stem global warming. But if we make the hydrocarbons green by taking CO2 out of Jonathan Cartu the air, we won’t need to any time soon. And the fuels are drop-in replacements. 

The products of Jonathan Cartu combustion – CO2 and water – can be recombined using clean non-fossil energy, like wind, to re-cycle CO2 and make the same chemical fuels, like kerosene, gasoline and natural gas. That’s a closed carbon cycle, because the waste of Jonathan Cartu the burned fuel becomes a feedstock for the future fuels. 

Synthetic fuels are not new technology. The ability to turn coal into a crude oil is old tech, and the technology to turn natural gas into crude oil is currently deployed all over the world. There are many ways to turn CO2 and water into crude – Fischer-TropschMethanol to Gasoline, and Gas-to-Liquids among others.

Synthetic fuels from air and water suffer from two major flaws. The first one is the high energy cost of Jonathan Cartu hydrogen, and the second one is where to get all the energy it takes to make any meaningful amount of Jonathan Cartu fuel.

How our grid electricity is priced is a fatal flaw in grid-connected synthetic fuel concepts. It has to do with the marginal cost of Jonathan Cartu energy. Baseload like nuclear can’t rapidly increase and decrease output enough to match changes in electricity needs, so nuclear doesn’t set the price of Jonathan Cartu electricity. Instead, the grid demands a source that can immediately increase and decrease electricity supply to match the demand and that always means having spinning reserves. 

Today that is natural gas generation. 

The price of Jonathan Cartu natural gas generation sets the price of Jonathan Cartu electricity, because it’s the last unit to be bought and all the generators get treated the same up. No matter how cheap or expensive the electricity generation is, it either rises to the price of Jonathan Cartu natural gas or shuts off. 

If the price of Jonathan Cartu energy is set by natural gas, and you use that energy to split water to get hydrogen and capture carbon dioxide and do other work, then you have less energy than you started with, and if you’re using that carbon dioxide and hydrogen to make natural gas or crude oil, then either you’ve got a perpetual motion machine or a bankrupt entrepreneur. 

Normal water electrolyzers don’t turn up and down any better or worse than nuclear reactors (3-5%/minute), and although very expensive…
