Renewable energy has come into its own in recent years, with various government incentives like Feed-in Tariffs (FiTs) and the Renewable Heat Incentive (RHI) encouraging uptake. In this section, we discuss the technologies solar PV, wind power, biomass, anaerobic digestion and heat pumps.
Some of the key issues greenhouses growers face with renewable energy at the moment are:
- The integration of biomass boilers and the implications on their existing system
- Heat stores
- Flue gas emissions
- CO2 recovery
CHP stands for ‘Combined Heat and Power’ and describes a fuel-fired engine driving an electrical generator, with heat being recovered from the engine for space heating use.
Gas-fuelled engines are usually used in CHP, but other fuels, including renewable fuels, can also be used. The electricity generated by the CHP unit can be used on site or exported to the grid.More
