Sustainable urban Planning with Innovative and low energy Thermal And power Generation frOm Residual And renewable Sources

To demonstrate a highly replicable, cost-effective and high energy efficiency large scale energy generation system that will allow sustainable urban planning of very low energy city districts.

OBJETIVE: “Efficient integration of city districts with industrial parks through smart thermal grids”.

INDUSTRY = from energy consumer to ENERGY SUPPLIER

FRAMEWORK AND SCOPE

01

PITAGORAS project focuses on the efficient integration

• f city districts with industrial parks through smart thermal

grids. Technologies and concepts for low and medium temperature waste heat recovery and heat (and power) supply to cities will be developed and demonstrated.

FRAMEWORK AND SCOPE

01

Main Focus: waste heat recovery from industry and renewable energy generation and its use as an energy source to cities.

INDUSTRY from energy consumer to ENERGY SUPPLIER

FRAMEWORK AND SCOPE

01



Objectives of the European Union (EU) for the year 2020: to reduce energy consumption by 20%, to reduce greenhouse gas emissions by 20%, to have 20% of total energy consumption in

• btained from Renewable Energy Sources (RES).



Cities are responsible for about 70% of the overall primary energy consumption, and this share is expected to increase to 75% by 2030 (IEA, 2008c).



Development of low energy solutions for thermal energy supply to cities is one of the main needs

• f our society.



One of the sources with the highest potential nowadays is the recovery of waste heat.



Industries are throwing away large amount of energy. A 40% of the consumed energy in industries is waste heat (usually a very valuable energy).

FRAMEWORK AND SCOPE

01

Involved systems and concepts (to be optimised in the framework of the project): > Waste heat recovery system > Organic Rankine Cycle for heat and power generation > Seasonal thermal energy storage system > Integration with high efficiency heat pumps > Solar thermal energy > Integration of new technologies, concepts and systems developed and state-of-the-art systems > Innovative tools for efficient energy management at component, building, district and city level

FRAMEWORK AND SCOPE

01

The main breakthrough of the project is the overall system integration and optimization. All the technologies that will be considered are proven technologies; the project is not focused on technological developments but integration: overall system conception. The developed concepts and systems will be tested and validated under real conditions in the demonstration plants of Brescia (Italy). An specific case will be studied at Kremsmünster (Austria) with solar thermal energy to be used for industrial use and DH supply.

AT EUROPEAN LEVEL

In the USA:



The total energy consumption is 78 quads (1 quad = 293 x 109 kWh)



The industrial sector consumes 28 quads



The waste heat energy discharged is 11 quads The industrial waste heat amounts to 14% of US total energy consumption and 39% of the industrial energy consumption. In Europe:



The percentage of available waste heat in industry in Europe is close to that in the USA [1]



European industry generates annually approximately 4.000 TWh

• f waste heat, which is equivalent to the incident solar radiation in 3.300.000 Km2

(aprox. 1/3 of the total area of Europe).

AT EUROPEAN LEVEL



Assuming that 50% of total available waste heat can be recovered this means that we would have 2,000 TWh of useful heat per year to use.



This amount of energy is equivalent to 17,000 million m3 of natural gas.



The use of this amount of waste heat for heating, cooling and power generation would mean to save more than 2,000TWh of fossil fuels, that is, a reduction in GHG emissions

• f about 4,500 million tonCO2/year.

LOCAL IMPACT - BRESCIA (ITALY)



The demonstration plant will be implemented in the steel foundry owned by ORI MARTIN. The waste heat recovery system will be implemented into the flue way and an ORC unit for approximately 2.1 MW (electrical capacity) will be installed for heat and power generation. Heat will be delivered to the existing district heating network.



Waste heat will be recovered mainly from the Electric Arc Furnace, which is in operation 6.800 hours/year. It is estimated that 61,560 MWh/year will be recovered and 6,300 MWh/year of electricity and 30,000 MWh/year of heat (to the city) will be generated.



In 2012 the city DH network has been supplied by renewable energy (55%), methane (30%) and coal (15%). The Pitagoras pilot plant will reduce the part supplied by fossil fuels increasing the fraction covered by RES. The total heat demand supplied by the city DH network was about 1,4 TWh in 2012; it is estimated that 2.1% of heat supply will be covered by PITAGORAS pilot plant.



With PITAGORAS project contribution the payback time is estimated in about 6 years.

LOCAL IMPACT - KREMSMÜNSTER (AUSTRIA)

 The case study of the city of Kremsmünster will be based on a STES system of about 60.000

m3 that stores the waste heat from industry and the heat produced by the solar thermal plant (appr. 10.000m2).

 Kremsmünster is a city in upper Austria with a 30 year old DH network. Currently 65% of the

thermal energy consumed in the city is covered by DH (20 GWh/year). Heat sources in the DH system are a CHP plant (75%) and a gas boiler (25%).

 A storage tank (60,000m3) that was in the past used in an oil and gas company for oil storage and

that currently is unutilized will be reconvert for the usage as long term energy storage (STES).

 This pilot plant establishes several sustainable benefits, as the followings:  Substitution of fossil fuels of gas boiler (appr. 3.5 GWh/year)  Significant share of RES trough solar thermal system (25%) in the city DH supply  CO2 savings of appr. 1,500 ton/year  Individual system management of CHP plant  Covering load peaks of DH demand  Extension of DH supply through renewable energy (solar thermal)  Illuminating project with highly replicable multiplication factor for Austrian and European cities.
