I have heard it right from the horses mouth that the Inresol sterling engine CHP is finally up and running and deliveries to distributors/dealers are to commence soon. for those who don't know it is a sterling engine CHP giving 5kw of electricity (up to 10kw with battery backup) and 15kw of heat per hour from about 3kg of pellets, it has the ability to take inputs from solar PV, it has the option of a battery backup, it can have multiple units connected together in a shipping container to form a power station. it has been tested using most types of fuel, mains gas, kerosene,diesel,lpg,nut shells,pellets,wood chips g30,almost anything that burns and can be fed in to the burner.at the moment I dont think the mains gas, liquid fuel options are available because the pellet/chip version is more attractive . https://www.inresol.se/where-to-find
