A system comprising a cryogenic engine system and a refrigeration system, wherein the cryogenic engine system and the refrigeration system are mechanically and/or thermally coupled with each other. The refrigeration system is driven by the cryogenic engine system and the cryogenic engine system enhances cooling of the refrigeration system.

Refrigeration

The present invention provides a method of operating an engine () having one or more cylinders () each having a piston () within the cylinder () and each piston () having an expansion stroke and a return stroke and a top dead center (TDC) position and a bottom dead center position (BDC) and said engine () employing a working fluid (WF) and a heat exchange fluid (HEF), comprising the steps of: introducing the HEF during the return stroke of the engine; introducing the working fluid (WF) during the expansion stroke of the engine; causing the exhaust valve to be opened at or near bottom dead center of the piston BDC; delivering the HEF to the cylinder () after the exhaust valve has been opened; and closing the exhaust valve before TDC, such as to allow the working fluid to be compressed by the piston within the cylinder. The invention also provides an engine () capable of being operated in accordance with the method.

Cryogenic engine system

Methods and apparatus for storing thermal energy are disclosed. The thermal energy may be hot or cold. The methods and apparatus allow the thermal store to be charged and discharged at different rates. The methods and apparatus also allow the thermal store to be charged and discharged with multiple and/or interrupted phases.

Method and apparatus for storing thermal energy in thermal masses for electricity generation

A system () comprises a cryogenic engine () and a power generation apparatus, wherein the cryogenic engine and the power generation apparatus are coupled with each other to permit the cryogenic engine () and the power generation apparatus to work co-operatively with each other in a synergistic manner. The cryogenic engine () and the power generation apparatus are mechanically and optionally thermally coupled with each other so that the output means is shared between the cryogenic engine () and the power generation apparatus and that the two systems can be operated in the most power efficient manner and may also thermally interact to the potential advantage of both performance and economy.
