Multifuel automotive engine-derived systems for clean grid load balancing and non-grid electricity applications

An electricity generation system, wherein the electricity generation system uses multiple engine powered generators;

• wherein at least one engine is a spark ignition engine;
• wherein the at least one engine is operated with fueling of natural gas and/or with a second fuel;
• wherein the second fuel is ethanol, an ethanol-gasoline mixture, methanol or gasoline;
• wherein the at least one engine powers a generator that provides DC electricity;
• and
• wherein the electricity generation system produces DC electricity that is provided by a combination of DC electricity from multiple engine generators.

An electricity generation system wherein the electricity generation system uses multiple engine powered generators;

• wherein at least one engine is a spark ignition engine;
• wherein exhaust from the at least one engine passes through a three-way catalyst;
• wherein exhaust gas that has passed through the three-way catalyst passes through an SCR catalyst;
• and
• wherein the SCR catalyst reduces NOx in the exhaust gas that passes through it.

An engine powered generator that is used to provide electricity for charging a battery of an electric vehicle;

• wherein the engine is a spark ignition engine;
• wherein the spark ignition engine is a modified automotive engine or a modified truck engine;
• wherein the spark ignition engine is operated with fueling of at least one of hydrogen or a hydrogen-rich gas;
• wherein the engine powered generator provides DC electricity;
• wherein speed of the engine can be varied;
• and
• wherein the power output of the engine can be varied by varying the speed of the engine.
