The Star Neatpump
SRE at this stage is focussed on Heatpumps although other forms of low carbon or alternative energy may be added to the unit. Whilst heatpumps have been known in engineering circles since the late 1800s, market deployment has been limited to situations where "normal" sources of heat were constrained. Switzerland in the 1940s for example had a significant hydroelectricity resource but limited access to fossil fuel so began to deploy heatpumps for building and water heating.
Today in Northern Europe heating accounts for around 50% of the fuel consumed in society. In Britain this is half of approximately £32b/a fuel spend. Heatpumps can deliver energy harvested from one place in a ratio of upto 10:1 vs "drive fuel consumed". Typically this fuel being electricity.
All heatpumps have a varying Coefficient of Performance (or COPh) depending on many factors such as temperature of source, temperature of demand, working fluid inside the system, major component design and system design. Star Refrigeration's work at Drammen in Norway was a seminal moment in heatpump design. For the first time in history a system delivered 90C using ammonia and at 14000kW this is more than just a pilot plant. The use of heat is varied across several businesses including houses which alone would number 6000 or so. With sources of heat increasingly understood including rivers, sewage treatment plants, process industries, datacentres, and underground aquifers, large heatpumps in pretty much any location in the UK can be considered viable for 500kW and 70C or even bigger.
