Renewing energy and decreasing the use of fossil fuels is a way to decrease carbon emissions and increase European energy independence.

In some cases, there is introduced the possibility replace fossil gasoline by using canola oil and alcohol along with other hydrocarbons and catalysts (ethanol, methanol, potassium chloride, etc.) mixtures. 

Also, methane that forms in the natural rotting process can use as fuel. The methane is possible to clean. Or the system can remove carbon from methane by using carbon filters. 

Renewable energy and decreasing the use of fuel are key roles in the new energy solutions. In a hydrogen economy, we want to think of hydrogen as fuel. The way how to produce hydrogen determines its carbon emissions. If we use things like geothermal energy for hydrogen production that thing makes that gas very ecologic. In the same way, we can connect hydrogen production with other electrolytic processes.

If we can produce hydrogen with other electrolytic processes, that makes it more energy effective. So if the production of sodium and chloride is connected with hydrogen production, that thing makes it more effective. But there is another way to produce hydrogen. That thing is just removing carbon from natural gas. 

The system can also drive natural gas simply through carbon filters. That filter removes carbon from the exhaust gases of the engines. 

In this process, the carbon will use to remove carbon from methane. The methane will conduct through carbon filters. In the same way, the carbon filters that are used in gas masks can remove carbon from carbon dioxide. 

Engineers created that technology for removing carbon diesel engines' exhaust gas. And that made it possible that submarines could use diesel engines or gas turbines in underwater conditions. 

The diesel-electric submarines required diesel for loading their batteries. When that submarine drives underwater it uses electric engines. But the weakness of that system is that it needs to reload its batteries. 

And if that thing could be made deep underwater the submarine would be less vulnerable. Normally diesel-electric submarines use a snorkel or a tube pair when they load their batteries. Another tube exhaust the exhaust gas. 

And another tube will drive oxygen to the engine. Also driving the inner air of the submarine through carbon filters makes it possible to remove carbon dioxide from the submarine's breathing air. 

Making similar fuel bubbles to that thermobaric vacuum bombs create makes it possible to decrease fuel use. 

When we want to decrease emissions, we must decrease fuel use. The idea is simply the combustion engine must make the needed pressure that makes the piston move by using something more than just fuel. The simplest way to make that is to use water with fuel. In that case, the system injects water along with vaporized fuel in the system. The most advanced method system covers the water droplet by using fuel. In that system the fuel burns on the surface of the water droplet. 

One version of those new systems is to use a system that makes bubbles in the combustion chamber. The idea is taken from the thermobaric vacuum bomb. 

If the system makes a fuel bubble, where the fire front moves on the surface of that fuel bubble that is filled by air. In that version, the injection system will make a bubble of fuel fog, and then the system injects oxygen into that bubble. That makes the hollow fuel core for that bubble. And it decreases the use of fuel.

That thing makes it possible to create high pressure by using a smaller mass of fuel than using normal fuel systems.
