[bionet.technology.conversion] ENERGY: CNRE - Liquid Fuels from Biomass Programme

P2269@com.qz.se ("ENG-LEONG FOO ", MIRCEN-STOCKHOLM) (10/05/89)

On 2-4 Dec 1987, CNRE held a yechnical consultation on Liquid
Fuels from Biomass in France -
- to evaluate and conduct a survey on the state-of-the-art of
  producing liquid fuels from biomass
- to discuss the technical-econiomic barriers of future development
  of liquid bio-fuel production technologies

The consultation was attended by 33 paerticipants with 24 presentations
Topics covered were :
- technical-economic aspects of producing liquid fuels from biomass
- utilization of liquid biofuels in current and future emgines
- macro-economic aspects of producing liquid fuels in European
  countries.
Several issues and problems were discussed :
- Though technically feasible with wide scale R & D activities
  exist for (a) plant oil production for substitution of diesel
  (b) bio-ethanol production as an additive to gasoline (c) enzymatic
  and acid hydrolysis of ligno-cellulosic materials, the participants
  agreed that if usual subsidies cannot be taken into account
  due to the present low-level of international oil prices, then
  none of the technical feasible technologies can be profitable
due to the high ratio and level of raw material costs.
- Though faced with this primary problem, the consultation recommended
  to acrry on the national R & D programmes and international
  cooperation in this field of rural energy development because
  in the long-term prospective bio-liquid fuel production can
  considerably contribute to -
  a) rational use of low quality and marginal lands
  b) extension of farmers' employment and income
  c) improvement of environmental and ecological conditions.

Recommendations:
- Dr A.V.Bridgewater (UK) was invited to act as chairman of the
  working group for 1988-1990 and to prepare a State-of-the-Art
  study on Liquid fuels from Biomass.
- three topics were recommended for further research
  (a) development of plant oil production technologies
  (b) improvement of bio-ethanol technologies
  (c) elaboration of economic evaluation methodology for
      comparison of various projects
