Table 1 Rationale used to develop the accelerated technology development (ATD) scenarios for the five technologies.

From: How can accelerated development of bioenergy contribute to the future UK energy mix? Insights from a MARKAL modelling exercise

Technology cluster Rationale for ATD Key changes in datasets Key references
Lignocellulosic conversion to ethanol Improvement in feedstock quality Better conversion technologies
Cheaper enzymes
Availability
Efficiency
Investment costs
O&M costs
R. Slade (unpublished data); [28]
Gasification of solid biomass (energy crops) Increased fuel flexibility
Cheaper feedstocks
Cleaner gas production
Availability
Efficiency
Capital costs
Fixed O&M costs
J. Brammer (unpublished data); [25, 29]
Fast pyrolysis Better grade/cleaner oil
Improved feedstocks
Increased fuel flexibility
Cost reductions associated with the above

Bioengineering of energy plants Increased yield
Increased stress tolerance, and disease and pest resistance
Increased nitrogen and water efficiency
Improved yield and energy content of energy plant [12, 20, 24, 3034]
Agro-machinery of growing and harvesting energy crops Improved establishment on marginal/idle land
Increased efficiency at picking up cut crops
Improvement in irrigation systems
Improved site preparation methods and weed elimination methods
