Powering a electric vehicle or construction equipment with CO2 hydraulic motors and pistons Infinity Turbine is experimenting with a CO2 driven hydraulic motor for construction equipment and electric vehicles. This ground breaking technology has a better overall COP than a standard battery-to-electric motor cycle. |

How it works Heat liquid CO2 to 30 C (87 F) and it goes supercritical (above 1,000 psi). So why not use this for linear actuators (pistons) and hydraulic motors ? |

High COP In the HVAC industry, it is well known that a heat pump is more efficient than straight electricity (kW) to heat. By using phase change dynamics, you can get better performance, measured by COP (coefficient of performance). |

How to pressurized liquid CO2 There are many methods of bringing CO2 from liquid to gas, or going supercritical.One method is direct heat of 30 C (87F) or higher temp. This can be provided by electricity, solar thermal, waste heat, induction heating, and more.Another method is by cavitating liquid CO2 by spinning a cavitation device in the liquid. We've experimented with that, and it works.Conventional methods of pressurizing CO2 from a liquid is using a piston pump, similar to the Cat310 pump modified for CO2 service. We've built about 100 supercritical CO2 pump botanical extractors using this process, and it works well. Piston pumps require a electric motor with a gearbox to operate, and have many seals which require replacement (consumables).Is spinning a disc to cavitate liquid CO2 more efficient than a Cat310 piston pump ? We think so. At the very least, it provides a more cost effective and virtually maintenance free method of pressurizing CO2. |

Is a electric vehicle with hydraulic motors more efficient than electric motors We are currently studying the dynamics of using battery power to power a heat-pump device which provides pressurized CO2 to hydraulic motors which provide motive power. This is especially interesting for construction equipment including steady-state conveyors, but is also applicable for hydraulic motors to drive wheels, tracks, and marine use propellers. |
