Torque characteristic and momentary respond
The steam engine will provide very high torque already from zero
shaft speed and with a proper designed engine, gear box can be
eliminated in automotive applications. A steam engine will provide
instant response to power demand if steam is available without
any lag and delay . Modern compact steam generators and a so called
steam buffer will promptly provide the steam engine with steam.
The torque characteristic is excellent for automotive applications
with high low end torque and an elastic torque profile.
The prompt response is important also for CHP applications

Hybrids
SSSP makes it possible to realise hybrids (combicycles ) with
high efficiency at significant load. Hybrids also offer APU (
Auxiliary Power Units ) features in automotive applications and
backup features in CHP applications. Hybrids offer also higher
flexibility to meet mismatch between electricity and heat demand.
The SSSP can act as bottoming cycle together with almost any kind
of prime mover as ICE and the development of the ceramic gasturbine
with higher temperature should justify the micro bottoming cycle
concept further. SSSP is also interesting as bottoming cycles
together with the emerging high temperature fuel cells.
