SCORELCA

Logo Scorelca« We are partners of the SCORELCA network, a cooperative LCA and environmental quantification research structure created on the initiative of some leading French companies (EDF, Engie, Renault, Saint-Gobain, TotalEnergies and Veolia), with the support of ADEME. Its objectives are to :

  • define LCA research programs,
  • facilitate exchange between the various players involved in the use of LCA with a view to establishing best practices in the field,
  • contribute to European and international scientific dialog for the purposes of technological intelligence concerning LCA.
     

In particular, we have built a state of the art in the field of prospective energy and resource analyses, and developed a methodology to guide LCA practitioners wishing to carry out a prospective LCA. We have also drawn up a state of the art concerning the incorporation of the spatial dimension in LCA and proposed practical recommendations concerning its integration in different studies. »

European SCelecTRA (Scenarios for the electrification of Transport)

Scelectra - logo«We coordinated the SCelecTRA project as part of the ERANET- Electromobility program, the objectives of which were to:

  • identify public policies promoting the development of European electric mobility out to the year 203,
  • evaluate their environmental impacts and external costs.
     
Projet Scelectra


The main conclusions of the project relate to the following areas:

  • electric vehicle penetration scenarios for the European market by 2030: more than sixty or so scenarios were generated using a Times economic optimization model. The most optimistic scenario reveals that the share of electric vehicles in the European car market could be as high as 30%,
  • the environmental benefits of electric vehicles: the report emphasizes the importance of the battery production component in the overall environmental assessment of electric vehicles,
  • the study of public policy instruments revealed that scrappage schemes and electric vehicle purchase incentive programs are more effective than measures relating to fuel taxes,
  • the development of a network of recharging terminals is a decisive factor in the development of the electric vehicle market,
  • the additional demand for electricity will be covered by new capacity rather than lower consumption in other sectors.»

From attributional LCA to consequential LCA

«Our economic engineers work on methods enabling us to assess the performance of the energy and transport sectors. Areas tackled recently include the analysis of the environmental challenges of mobility, biofuels and biobased products, as well as energy storage solutions. The quality of our studies stems from the systemic approach employed:

  • an attributional LCA refers to an environmental assessment conducted at a given point in time “t”: it incorporates a description of physical flows but it does not make it possible, when used alone, to predict the impact on a sector of the creation of a new industrial process;
  • we therefore propose combining these traditional LCAs with economic and energy scenarios, capable of quantifying the environmental consequences of political and industrial decisions on a large scale. This new approach, known as consequential LCA, takes into account one or more economic sectors, the energy and transport sectors, or the entire economy. It is based on energy system scenario models. For example, we used it to study the impact of the emergence of BtL (Biomass to Liquid) biofuel production technology in France by 2030 (in French). »

Economic, energy and environmental study for French road transport technologies(E4T)

Etude E4T

«In July 2018, we published a final report concerning the study conducted in partnership with the ADEME (French Environment and Energy Management Agency), giving a cross-functional assessment of the impact of electrification by segment in France. This document offers an analysis of the major trends concerning electrification technologies currently being introduced or developed.

Globally, this summary report highlights the fact that :

  • with the exception of the long-haul heavy truck segment, the conventional powertrain (gasoline or diesel) will be facing stiff competition in 2030, be it from the point of view of total cost of ownership (TCO) or its environmental impact (Greenhouse Gas [GG] and pollutant emissions). These powertrains will thus be in considerably less widespread use by 2030,
  • 48V Mild Hybrid (MHEV 48V) architecture, pushed to maximum performance, may be a promising solution to compete with current power-split Full Hybrid (HEV) solutions,
  • plug-in electric vehicles (PHEV) seem to be the most appropriate solutions from the point of view of the impact on GG emissions, thanks to their reduced-sized battery, perfectly suited to most vehicle use. However, in the absence of help-to-buy initiatives, their economic profitability remains a barrier to their roll-out,
  • electric vehicles (BEV) are effective solutions for reducing local pollution and GG emissions, especially if they are widely used (buses for example) so as to absorb the impact of manufacturing the battery. Nevertheless, the economic profitability of these solutions remains limited currently (although they are supported by help-to-buy initiatives) but should improve by 2030 thanks to the probable reduction in the cost of the batteries,
  • the current trend towards bigger battery sizes in order to increase the range of electric vehicles has a detrimental impact on GG emissions generated by the electric vehicle sector. Further research is likely to be conducted in this area in the future.»

Techno-economic and Life Cycle Assessment of methane production via biogas upgrading and power-to-gas technology study

«The increasing use of renewable energies, which by their very nature are variable, means that surplus electricity produced during periods of over-production has to be converted into a form that can be stored. Converting electricity into gas is one way to solve this problem, because the method enables the surplus electricity to be stored for later use. The technology behind the solution is power-to-gas, which consists in:

  • using electricity to convert water into hydrogen via electrolysis,
  • synthesizing methane from carbon dioxide and hydrogen.
     

We conducted a technical and economic and LCA analysis of methane production via a combination of anaerobic digestion and power-to-gas technology applied to the conversion of treatment plant sludge.
 
Several conclusions emerge from our study :

  • the more expensive electricity is, the longer the operation time of the methanization process must be in order to be competitive with the injection of methane from biogas,
  • reducing the electricity consumption of the electrolysis step reduces production costs,
  • from an environmental point of view, continuous power-to-gas generates more greenhouse gases than direct injection, but intermittent operations with renewable electricity can reduce emissions considerably,
  • the impact of continuous power-to-gas is greater than biogas conversion, but lower than fossil energy,
  • the future development of low electricity consumption associated with the electrolysis process and the integration of renewable credits from CO2 conversion could increase the competitiveness of this technology.»

Life cycle analysis (LCA)

Life cycle analysis (LCA)
OVERVIEW AND CHALLENGES

Life Cycle Analysis (LCA) is an assessment method aimed at quantifying the environmental impacts of a product or a service, as part of an eco-design approach or with a view to selecting the optimal solution. All the potential impacts on the environment are quantified and the consumption of resources is examined, from extraction of raw materials to treatment of waste (“from cradle to grave”).

It is therefore a global, multi-step and multi-criteria approach, governed by a standard (ISO 14040-44) and recommended by the European Union. LCA developed rapidly from the 1980s and it is now used by:

  • international, European and national public bodies,
  • the scientific community,
  • industrial players.
     

In practice, it takes a variety of forms to:

  • take into account specific regional and sector-based characteristics,
  • incorporate new criteria, such as:
    • the risk of water shortage,
    • the monetization of environmental impacts,
    • new climate change indicators.
       

Today, LCA is an invaluable tool for assessing the impacts on the environment of activities linked to new energy systems. It is used to identify :

  • the principal sources of pollution,
  • opportunities to improve the environmental performance of products and services at various stages of their life cycle.

 

Conduct studies and develop methodologies to support decision-making and guide R&D strategies.
