El från nya och framtida anläggningar 2011

This report constitutes an updating and summary of the reports El från nya anläggningar 2007, which elaborates on the electricity generation technologies being implemented in new plants and the associated electricity productions costs at that time, and Future electricity and heat production technologies, which looks into continued development of today’s commercial technologies and potential technological developments in the future.

The objective of the report series ”El från nya och framtida anläggningar” is to get an integrated and up to date picture of the situation 2010 concerning electricity production costs based on commercially available and reliable technologies to be able to compare different energy sources with one another in a more comprehensible way. Some technologies have been included that are characterised as new but still in a development phase and therefore less tested with regard to reliability. The scope also involves a forward-looking approach trying to estimate the costs of today’s as well as developing technologies towards 2020-2025.

For technical descriptions of electricity generating plants earlier dealt with, reference is made to the above mentioned reports. New technologies that has not been discussed earlier plus necessary complementary additions are included in the present report.

The updates include and involve also an expanded computer based model, in Excel, for calculation and presentation of the electricity production costs as well as for sensitivity analysis related to essential input factors/quantities and conditions representing Swedish circumstances.

Technologies

In this first version of ”El från nya och framtida anläggningar” 14 new plant types or variants have been added in relation to the previous version of “El från nya anläggningar 2007”. Worthwhile mentioning is:

• A small biomass fuel fired CHP rated at 5 MWe

• A CHP 20 MWe burning sorted waste fuels “RDF”

• A CHP 20 MWe for thermal gasification of sorted waste fuels “RDF”

• Condensing plants with CCS (for both coal and natural gas)

• A biomass fired plant with an ORC-process rated at 2 MWe

• A waste heat driven ORC-process rated at 0,5 MWe

• A small hydro power station at 5 MWe

• Solar cells (PV) at 50 kWe

• Thermal gasification of biomass with internal combustion engine rated at 1, 5 and 10 MWe respectively

• A fuel cell (MCFC) for biogas rated at 500 kWe

• A fuel cell (PEFC) for natural gas rated at 50 kWe

• Thermal gasification of biomass with combined cycle – CHP rated at 20 and 60 MWe respectively

In addition to the above a number of new versions of formerly described technologies have been included. For the fast developing wind power technology new wind turbines based on increased tower heights, increased wing/rotor diameters and electric power capacities have been introduced along with increased wind park sizes.

A new type of plant that has been added is the “polygeneration” plants based on biomass fuels – “biomass polygeneration”. The denomination is used to characterise that production of several different products are integrated in a common process in order to achieve synergies and maximise the total energy usage. In this first version of the report two biomass poly generation plants have been introduced and elaborated upon, one for production of vehicle fuel (biomethane/CH4) and another for pellets.

The focus of attention in this version of the report relates to presentation of updated and new data for plants that are assumed be commercial or “semicommercial” in 2010. Towards 2020-25 the presentation is reflecting rather the development potential and preliminary assessment of data and costs provided that relevant basic data exists.
