Micro DE - Micro DE Technology Comparisons

Abstract:

The Micro DE project was a scoping and feasibility study to identify opportunities for micro-generation storage and control technology development at an individual dwelling level in the UK. The study investigated the potential for reducing energy consumption and CO₂ emissions through Distributed Energy (DE) technologies. This was achieved through the development of a segmented model of the UK housing stock supplemented with detailed, real-time supply and demand energy-usage gathered from field trials of micro distributed generation and storage technology in conjunction with building control systems. The outputs of this project now feed into the Smart Systems and Heat programme.

This deliverable presents a methodological approach and a mapping decision tool to rank the different DE technologies solutions for the 2010 and 2030 scenario. This decision approach shouldbe used to decide the level of new incentives scheme to promote DE technologies, in terms of cost investment or energy bill incentives. This deliverable is number 4 of 7 in Work Package 3. It is in 3 parts:

• 3.4.1 Roadmap for Micro DE Technologies. This report summarises the views of the consortium regarding future performance of micro DE technologies
• 3.4.2 Micro DE Technology Comparisons. This report provides a comparison of the performance capabilities of different micro DE technologies in 2010 and 2040, based on analysis carried out in the model developed as part of the project The DE technologies analysed or monitored in this project are the following:
  • Biomass
  • Condensing gas boiler
  • Micro-CHP system
  • Heat-pump (Air source heat pump and ground source heat pump)
  • Solar PV -Solar thermal
  • Small wind turbine (P < 5 kW).
• The aim of this work is to compare the ranked micro-DE solutions results for 2 scenarios:
  • a 2010 scenario,
  • a 2030 scenario, with updated parameters for efficiencies of the DE technologies installed, CO₂ intensities and average kWh cost per energy
• 3.4.3 Micro DE Technology Case Studies. This report provides 3 case studies around the potential deployment of micro DE technologies in properties in the 2010 / 2020 / 2040 timeframes, aligning with the scenario analysis carried out in report 3.5.

• biomass solutions alone or combined with renewable DE technologies such as Solar Thermal, Small Wind Turbine or Solar PV ,
• Followed by the electrical solutions with heat pumps (first, GSHP with a COP of 4 then ASHP with a COP of 2.9) combined with Solar PV, Small Wind Turbine or Solar Thermal.
• The gas solutions are not ranked in the 10 best solutions.
