Combined heat and power
Small-scale CHP schemes: to meet space and water heating requirements in buildings, based on spark ignition reciprocating engines
Large-scale CHP schemes: for steam raising in industrial and large buildings, based on compression ignition reciprocating engines, steam turbines or gas turbines
Large scale CHP schemes for district heating: based around a power station or waste incinerator with heat recovery supplying a local heating network
-
Backpressure steam turbine, condensing steam turbine, cogeneration with gas turbine, cogeneration with combined cycle
Microturbines
Compact, lightweight, low efficiency
-
Drop-in Biofuel
Liquid bio-hydrocarbons that are: functionally equivalent to petroleum fuels and fully compatible with existing petroleum infrastructure
Long distance transport cannot use batteries, so it must use drop-in biofuels to be renewable
