Copernicus Institute Sustainable Development and Innovation Management Integration… Pfff, it’s complex…

Copernicus Institute Sustainable Development and Innovation Management Key bioenergy utilisation routes

Copernicus Institute Sustainable Development and Innovation Management Bioenergy today 45 EJ + 10 EJ total use 9 EJ + 6 EJ commercial; non-modern ~ 8 EJ Modern; commercial: –< 1 EJ electricity –~ 2.5 EJ heat –~ 1.5 EJ biofuels (bulk = ethanol; half of that ethanol sugar cane based) Main controversy on biofuels from annual crops and palm oil. Currently some 20 Mha in use for biofuels worldwide (compared to 5,000 Mha for food)

Copernicus Institute Sustainable Development and Innovation Management Combustion; workhorse of bio-energy… Efficiency: from 20 – 40% CHP: 60 - <80% Capacity: 20 – 250 MWe … Economics OK with residues

Copernicus Institute Sustainable Development and Innovation Management Power Station Kymijärvi, Lahti Finland

Copernicus Institute Sustainable Development and Innovation Management Future BIG/CC technology -> Current status: ~3500 U$/kWe, 30% electrical efficiency, ACFB, ~10 Mwe -> Future:~1500,- U$/kWe, ~50% efficiency, (ACFB..), >100 MWe -> Ultimate: 55% eff., PCFB, HT gas cleaning >200 MWe Cost of electricity: ~ 10 U$ct/kWh -> 3-4 U$ct/kWh, almost doubling of electrical output [Faaij, van Ree et al., 1998]

Copernicus Institute Sustainable Development and Innovation Management Perennial crops (vs. annual crops) Lower costs (< 2 €/GJ) Planted for years Low(er) intensity – Can restore soil carbon and structure – Suited for marginal/degraded lands – Requires less inputs (well below key threshold values) Wide portfolio of species & production systems – Possibilities for enhancing (bio-) diversity – Adaptable to local circumstances (water, indigenous species) Earlier development stage – Large scale and diverse experience needed – Learning curve to be exploited – Improvement potential Miscanthus x giganteus

Copernicus Institute Sustainable Development and Innovation Management Synthetic fuels from biomass Biomass & coal gasification to FT liquids - with gas turbine Power Pre-treatment: - grinding - drying feedstock is poplar wood Gasification: - air or oxygen - pressurised or atmospheric - direct/indirect Gas cleaning: - ‘wet’ cold or ‘dry’ hot FT liquids Offgas Recycle loop FT synthesis: - slurry reactor or fixed bed Gas turbine Gas processing: - reforming - shift - CO 2 removal Major investments in IG-FT capacity ongoing in China right now: - Reducing dependency on oil imports! - Without capture strong increase in CO2 emissions… About 50% of carbon!

Copernicus Institute Sustainable Development and Innovation Management Closing remarks Technological and management improvements key factor: –Agricultural (and livestock) management! –Energy cropping & supply systems –Conversion. Technological learning and improvement potentials still fairly poorly covered in analyses around bioenergy (potentials & projections), agriculture a.o (especially 2 nd generation and beyond!). Combination of bottom-up engineering work and modelling generally gives good results. Takes considerable effort.
