DES combines electricity, cooling and heat supply by utilising local resources that can be generated into energy such as biomass, municipal solid waste, biogas, solar, wind, hydro and hydrogen. The integration of renewable energy technologies, storage and control system designed based on the available resources, cost, generation profile and user demand profile will ensure the resources are fully optimised.
Building owners, developers (housing/industrial/town), farm owners and industrial owners have huge potential in making use of the available natural resources and surplus heat to generate electricity, cooling and heat for their own use by selling the surplus to the primary grid. This system is a great solution for communities in rural areas that can’t be connected by the main power grid. Contrary to the conventional one source system such as PV system alone, our approach is to analyse the potential natural resources that can be used to generate electricity/cooling/heat, then design an integrated system to achieve the highest efficiency at the best cost price and lowest carbon emission. For example, a palm oil factory can benefit from its own micro grid using palm waste to power up anaerobic digester/gasifier integrated with solar panels and combined cooling and power engine to generate electricity and cooling, aided with control system and electrical storage. The waste from anaerobic digester/gasifier can be processed into fertiliser. Our aim is to minimise waste and optimise useful products. Surplus electricity from the onsite microgrid generator can be sold to the main grid using Feed in Tariff (FiT) programme.
