User:Genetics4good/Comparison of alternative ICE fuels

From Wikipedia, the free encyclopedia

This article compares the alternative fuels currently available for use in internal combustion engines, after conversion. Specific focus has been put on home production of the fuel and the amount of emissions.

ICE fuel Greenhouse Gas Emissions Energy output/m³ Fabrication requirements Difficulty to convert IC-engine to this fuel Storability Toxicity Remarks
Compressed air Emissionless ?W/m³ no land required, only air and accessibility of energy needed easy, only possible with certain IC engines such as quasiturbine. Other engines can (supposedly) not be converted long storability not toxic Compressed air works more or less as a energy storage, meaning that you need a fair amount of power first to convert to compressed air. Best option if you have a quasiturbine-engine
Pure Hydrogen Water ?W/m³ no land required, accessibility of water and electricity (in higher quantities than what is obtained in hydrogen) required. No electricity required if produced by microorganisms.[1][2][3] intermediate, depends on whether DIY or by kit short storability; needs to be stored under pressure in tanks to increase gas amounts and thus energy output. This can be done by either carbon nanotube tanks or keratine-based tanks.[4] not toxic none
Oxyhydrogen Water ?W/m³ no land required, accessibility of water and electricity required. No electricity required if produced by microorganisms.[5][6][7] intermediate, depends on whether DIY or by kit ? not toxic none
Liquid nitrogen Emissionless ?W/m³ no land required, accessibility of water and electricity required. No electricity required if produced by microorganisms. intermediate, depends on whether DIY or by kit ? not toxic none
Water Emissionless ?W/m³ no land required, accessibility of water and energy needed intermediate, depends on whether DIY or by kit ? not toxic no official documents, could still be a hoax
Hydrogen peroxide [8] Emissionless ?W/m³ no land required, accessibility of water and energy needed intermediate to hard, depends on whether DIY or by kit ? very toxic, make sure to eliminate potential skin contact hydrogen peroxide may also be mixed with ethanol (ratio 68%-32%)[9][10]
Hydrogen or oxyhydrogen-fossil fuel mixture[11] Yes. ?co² ?W/m³ fossil fuels not producible at home, accessibility of water and energy needed easy, by DIY method or by kit relative long storage of fissil fuels (several months), hydrogen/oxyhydrogen is made just before use toxic Dough ICE conversion is easy and relatively cheap to do, the use of the fossil fuels still makes mixture non-self producible and still polluting. Therefore a full hydrogen/oxyhydrogen is always preferred.
Ethanol, Biomethanol and Butanol fuel Yes. ?co² ?W/m³ arable land required, planted with trees for fruit or wood (depending on whether its used to produce ethanol or methanol/butanol intermediate to hard, depends on whether DIY or by kit ? dough ethanol is safe, methanol is very toxic, avoid inhalation, skin contact, ... aldough ICE conversion is very easy, much work to produce base fuel itself. Perhaps usable for eco-projects as trees

may clear area of possible pollution and as emissions may be directed underground with stationary engines using Carbon capture and storage. Besides using trees, other crops as straw can also be used and converted using elephants yeast.[12][13]

Gases as Syngas, Compressed natural gas (CNG) and HCNG Yes. ?co² ?W/m³ access to gas supplies required intermediate to hard, can be outsourced to professional ? ? access to gas reserves are mostly not available, not worth the conversion due to still fair amounts of pollution
Vegetable oils as Jatropha Yes. ?co² ?W/m³ arable land required, planted with trees for wood intermediate, somewhat harder than ethanol/methanol, ... as the engine needs to be preheated and is best a diesel ? not toxic much work to produce base fuel itself. Perhaps usable for eco-projects as trees

may clear area of possible pollution and as emissions may be directed underground with stationary engines using Carbon capture and storage. Also usable for project combating desertification as japtropha can thrive in sandy/arid environments and as the emissions may again be directed underground (see above)

Algae fuel (can be converted to biodiesel and vegetable oil) Yes. ?co² ?W/m³ access to gas supplies required intermediate, somewhat harder than ethanol/methanol, ... as the engine needs to be preheated and is best a diesel ? ? probably much work to produce base fuel itself. Perhaps usable for eco-projects as algae

may clear a seawater area of possible pollution and as emissions may be directed underground with stationary engines using Carbon capture and storage.
