If a battery was paired with a Bluegen then the economic advantage in the UK would become explosive. The cost of electricity that the energy company charges is approx. 11p/unit. It pay you for your electricity sold to them approx. 4.5p/unit. If you can use all the electricity that the Bluegen can generate you save 6.5p/unit the difference between the two. The cost of gas is approx. 4.0p/unit. 50% efficient = 8p/unit

Subsidy approx. = 13.5p/unit

Maint Approx £500 per yr

Profit without subsidy = 13.5+11p-8p = 16.5p/unit = £2168/yr -£500 = £1668/yr
