An assessment of the expected effect on energy consumption and CO2 emissions

Journal article (2002) - Dian Phylipsen, Kornelis Blok, Ernst Worrell, Jeroen De Beer
As part of its energy and climate policy the Dutch government has reached an agreement with the Dutch energy-intensive industry that is explicitly based on industry's relative energy efficiency performance. The energy efficiency of the Dutch industry is benchmarked against that of comparable industries in countries worldwide. In the agreement, industry is required to belong to the top-of-the-world in terms of energy efficiency. In return, the government refrains from implementing additional climate policies. This article assesses the potential effects of this agreement on energy consumption and CO2 emissions by comparing the current level of energy efficiency of the Dutch industry-including electricity production-to that of the most efficient countries and regions. At the current structure achieving the regional best practice level for the selected energy-intensive industries world result in a 5 ± 2% lower current primary energy consumption than the actual level. Most of the savings are expected in the petrochemical industry and in electricity generation. Avoided CO2 emissions would amount to 4 Mt CO2. A first estimate of the effect of the benchmarking agreement in 2012 suggests primary energy savings of 50-130 PJ or 4-9 Mt CO2 avoided compared to the estimated Business as Usual development (5-15%). This saving is smaller than what a continuation of the existing policies of Long-Term Agreements would probably deliver. ...

Techniques for the reduction of the specific energy consumption for iron and steel making are identified and characterized to assess the potential for future energy-efficiency improvement and research and development priorities. Worldwide average specific energy consumption for steel making is estimated to be 24 GJ/tonne. The most energy-efficient process requires 19 GJ/tonne for primary steel and 7 GJ/tonne for secondary steel. Seven specific smelting reduction processes and four groups of near-net-shape casting techniques are described and evaluated. In the longer term, the specific energy consumption for making steel from iron ore can be reduced to 12.5 GJ of primary steel per tonne. A further reduction of up to 2.5 GJ of crude steel per tonne may be achieved when techniques are developed that can recover and apply heat from the hot steel at a high temperature. The specific energy consumption for secondary steel making can be reduced to 3.5 GJ/tonne by energy-efficient melting and shaping techniques. ...

A method for identifying and characterizing technologies that can improve the energy efficiency in the long term is described and applied to the paper and board industry. Current papermaking processes require 3-9 GJ heat per tonne of paper, mainly for the removal of water that is added initially to the fibers, and 1.3-2.9 GJ electricity/tonne. The selection of technologies is based on the results of an energy analysis of a paper mill. Seven relevant technologies are described. It is concluded that in the future paper-mill a combination of new pressing and drying techniques, latent heat recovery systems, and a number of minor improvements can reduce the specific heat demand by 75-90% compared to the current average. The specific electricity consumption will remain about equal or will increase slightly. Investment costs will be lower than for conventional paper-making processes. Benefits other than energy-efficiency improvement, e.g., an improved paper quality or a higher production rate, are the driving forces for the development of the technologies. ...
