Published on: 7-1-2015 Micro CHP is a successor of the boiler and reduces CO2 emissions and primary energy consumption compared to a boiler. Currently in Europe looked for the development of micro-CHP systems with a capacity of about 1 kWe. This connection is sought with the average electricity consumption of a household. Different products are now available. It is expected that by 2020 the market will grow significantly, making possible in 2030 35% of the boiler market by micro-CHP can be replaced.
Development of the number of installed micro-CHP installations in EU households.
The current cost of a micro CHP (based on a Stirling engine, gas engine, fuel cell) is high, but price declines are expected economies of scale and learning effects. A learning curve of 15% predicted (and in Japan, where the market is more developed, though observed). Assuming a European market with 10 players and a learning curve of 15%, we expect that a system price of about € 4,000 per kW can be achieved. This price does not include benefits that may result from increase in value of the home, avoiding additional network costs etc.
To achieve this price level, set the industry big steps. Substantial cost reductions to be achieved and innovation to make products better. In addition, supply chains need to be built and new ways must be found to reach customers. Also stimulating policy. Local or national scale subsidy programs, such as some German countries needed. In addition, pilot projects, such Ene.Field be expanded to increase awareness, to encourage innovation and achieve cost reductions. The Ene.farm project in Japan, for example, resulted in a short time to 100,000 installed systems, and realized a hefty cost. In total could be saved annually 240 PJ of primary energy, and 14 megatons of CO2. This is more than the total consumption of 1.5 million households.
The market potential study of micro-cogeneration, completed during the European CODE 2 project map that there are big opportunities for micro-CHP in Europe.
The report calls for action include:
Encouraging cost reduction through demand creation using (local) incentives (such as in North Rhine-Westphalia)
Stimulate innovation and fame through labs as Ene.field
The study was developed through discussion with energy experts. CODE 2 project evaluates the policy, market conditions and awareness of cogeneration in each EU Member State. Click here for the market potential analysis for micro CHP in Europe.
