1 Case Study Application of UNFC-2009 to BioEnergy By James Primrose A Sugarcane Ethanol Plant in Brazil Palais des Nations, Geneva 18th November

2 What will we do in this session? Introduce a hypothetical Brazilian Sugarcane Ethanol Case Study Consider other Bioenergy Examples from a conceptual standpoint. Objectives: Provide an outline on how the UNFC classification might work in a Bioenergy scenario. Demonstrate the key decision points that need to be considered. Trigger discussions: classification may sometimes be subjective. Identify specific Bioenergy issues that need to be addressed in the Bioenergy Specification document 2

3 There are a number of key questions that we would like to have your opinion about 1. Can the UNFC-2009 be usefully applied to Bioenergy projects? Key E- and F-axis criteria / questions Access and Entitlement to the BioEnergy source (e.g. biomass) What business / access models exist? Which models demonstrate sufficient access/ entitlement? Treatment of non-energy co-products? What uncertainties to be taken into account under the G-axis? Can G4 quantities be usefully defined? Are there certain Bioenergy value chains that raise specific challenges? E F UNFC-2009 Categories Socio-Economic Viability Project Feasibility G Geological Knowledge 2. Future owner for the Bioenergy Specification? 3

4 Steam & Power Generation Pre-processing Sugarcane ethanol mill Out-grower cane Purchases from 3 rd parties typically annual contracts Potential for Bagasse import/export. Cane harvest Delivery & sampling Unloading Cane preparation Juice extraction Sugarcane input: 2.5 mtpa capacity, with expansion to 5 mtpa Juice Processing Ethanol production Bagasse residue Storage Bagasse Fermentation Sugar production Distillation & Dehydration Truck loading million litres of ethanol per year Juice treatment & filtering Evaporation Juice is converted sugar and ethanol (50:50 split) Cooking & crystallization Centrifuging & drying Bagging kt of sugar per year High-pressure boiler Power and steam for process energy Power export 4

5 Sugarcane Ethanol Project : Usina BioSucro Existing 2.5 Mtpa Crush Capacity Mill. Start-up Expected economic life-time 30 years (to 2038). produces typically a 55 :45 split of ethanol (~100 mill litres) and sugar (170 ktpa). Ability to swing production 60:40 either way. Surplus power from cogen export to grid. ~60% of cane from a portfolio of land leases Average lease lifetime ~ 6 years + with an option of a 1 yr extension / maintained on a rolling basis. ~40% cane from out-growers annual contracts. Sanctioned Project to expand capacity at mill to 5 Mpta. Planned commissioning date 2015 harvesting season. Project currently 70% mechanically complete. Expected Economic Lifetime 30 yrs (to 2045). Planned 50:50 ethanol / sugar split with ability to swing 60:40 either way. Increased cogen, increased power exports to grid. 60% : 40% leased : out-grower cane. Same average lease lifetime 6+1yrs. Cane planting underway. Product Monetization. Ethanol 80:20 split of sales to domestic market and for export. Sugar : Mixture of sales via a broker and direct to end-users annual contracts. Power : Mixture of spot and auction contracts 5

8 Key decisions Reference Point Marketable Energy Products Ethanol, and Power What about the sugar? Sugar output is not counted, but value considered in determination of project economic viability. Can we count the energy used in the process? Yes - power and heat generated for process energy is counted, but treated as non-sales. What units do we use? Wait for conversion document for all renewables For now, using barrels of ethanol (bbl) and terawatthours (TWh) heat and power 8

9 Axis E & F Classification Project Maturity Project Maturity relies on evidence of technical and commercial maturity. Technical criteria (F axis ) Commercial criteria (E axis) Access and Entitlement <- Key issue for BioEnergy Market and Sales Connectivity Authorisation and Commitment Economic Case Validation 9

10 Access and Entitlement Sugarcane Example What is the level confidence to the degree of access or entitlement to the land/ sugarcane? None of the feedstock is from land owned by the plant owner. Land equity could be reasonably assumed to demonstrate the highest confidence of access and entitlement to the land biomass source. 90% of the feedstock is from leased land. Possible categorisation Category Comment Current Leases E1 High confidence. Demonstrable contractual entitlement. Lease Extensions (1yr) E1 or E2 High to Moderate confidence. Demonstrable contractual entitlement to extend. Operational track record evidence? Reasonable expectations of extension. Lease Renewal E1 - E2 E3? Categorisation depends on evidence base. Is there a track record of renewals. Reasonable expectations of renewal. Competition? Treatment / evidence base required to assess the certainty of lease renewals/ extensions. Treatment of the 10% sourced from out-growers? Typically sourced via yearly contracts. Sugarcane operations in other regions / countries rely much more heavily on this means of accessing cane, sometimes it is the only option available. Raises broader issue of the level of Access / Entitlement from biomass/crops obtained from the market (spot or annual contracts). 10

11 General Bio-Energy Access / Entitlement Issues Multiple business models exist to access biomass for bioenergy. 4 generic cases. Land Equity. Plant Operator owns and produces the biomass feedstock. Lease. Plant operator leases the land and either cultivates the biomass directly or contracts to a 3 rd party. Stumpage. Similar to lease. An operator has the right to remove a waste/residue. Typically applies to forestry, but could apply to other ag wastes. Sourced from Market: Operator feedstock from market. Covers spot purchase to LT supply contracts. Are there other models that need to be considered? Raise other issues / questions? All three models would appear to provide demonstrable contractual / legal evidence of access / entitlement to the biomass source over a multi-year time frame Contract holder also holds the biomass supply risk. Typically shorter duration contracts. Not linked to a specific source. Contract holder may be exposed to a price/market risk but not to the supply risk from a specific source. 11

12 Description Access / Entitlement : Corn Ethanol? Plant owner contracts for grain supply with individual farmers annually and/or with a trader(s) spot or annually. Can involve a farm/plant Cooperative. Produces ethanol + animal feed. Questions / Issues Corn/Maize Feedstock Farmer Co-op? Simultaneous demonstration of access/entitlement to the source and market connectivity? Which value chain entities? Does a biomass supply contract (spot or term) equate to Access/Entitlement to the BioEnergy Source? Can Access/Entitlement be extended beyond the contractual terms of the supply contract? Is the plant operator expose to the source / supply risk vs a price risk? Situation replicated in other bioenergy supply chain where the biomass is accessed via commodity markets 12

13 Market and Sales Connectivity Are the conversion plant, storage and transport infrastructure in place to convert feedstock into an energy product? For how long? In the sugarcane ethanol case study: Technical lifetime of the conversion plant (30 years) Commercial project high confidence Lifetime extension by capex reinvestment Not yet commercial project. N.B: Access & Entitlement constraints may be more restrictive than the technical/economic lifetime of the conversion asset. 13

14 Authorisation and Commitment Is sanction / financial approval to develop the plant in place, including from any JV partners? In the sugarcane ethanol case study: Current plant is already operating Commercial project high confidence An expansion of plant capacity is currently in the final stages of the construction/commissioning process Commercial project high confidence Note that economically viable upgrades / technology enhancements, that are not yet sanctioned would be lower confidence (E2, E3). 14

15 Economic case validation Is there an economic model demonstrating commerciality? If this depends on policy support, what is the lifetime of the policy? Policy risks, potential termination or reduction of policy support may impact categorisation of all or some of the project s resources. In the sugarcane ethanol case study: The plant is commercially viable and no policy support is required Commercial project high confidence 15

16 What uncertainties to be taken into account under the G-axis? The G axis in the UNFC designates the level of confidence in the geological knowledge (i.e. the energy source) and potential recoverability of the quantities. Renewable Energy Specification extends this to cover meteorology, climatology, topography and other branches of geography, ecology, geography and geology. Possible Bioenergy related issues would include Biomass Yield Risks Weather related harvest risks. Sunshine, rainfall, frost etc Harvest recovery risks, (harvester performance, storage losses etc.) Pest / Pathogens. Long-term water, soil quality related risks. Biomass Conversion Risks Conversion efficiency/performance. E.g. microorganism performance, hygiene... Typically most projects would appropriately parameterise these risks. 16

17 Other Bioenergy Value Chains (1) Type Description Points to consider Vegetable oil biodiesel plant Plant owner contracts for vegetable oil with a cooperative annually, and buys on the spot market Produces biodiesel. This involves using nonrenewable methanol Who can claim reserves Proving access to feedstock Proving future market connectivity given changing policy climate Use of non renewable input Wood chip cofiring plant Coal plant owner contracts for supply of woodchips for 20 years These are co-fired with coal to produce power Who can claim reserves Proving access to feedstock Proving future market connectivity given changing policy climate

18 Other Bioenergy Value Chains (2) Type Description Points to consider Waste CHP plant Plant contracts with waste management company for waste supply over 20 years Produces heat and power Who can claim reserves Proving access to feedstock Changing feedstock quality Forestry residue pellet plant Large forestry owner sites a pellet plant at their forest. Also contracts additional feedstock from a neighbouring forest owner on a 10 year contract Produces pellets, sold to a distributor then to multiple small users and one power plant Who can claim reserves Proving access to feedstock Proving market connectivity 18

19 A Renewable Fuel Example Source Processing Losses Marketable Energy Products Liquid Fuel Storage Solid Fuel UNFC Common project characteristics: A defined level of investment, with an expected production profile Prerequisites such as gaining access to the resource and market, receiving authorization, and validation of the economic case As the project develops, risk declines and certainty of returns improves April 2014 ABLC Washington, D.C.

20 Implications BioEnergy covers a wide range of sectors, many with complex value / supply chains. Multiple models exist of gaining access to the biomass (re)source. In some cases there may well be no single entity that can simultaneously demonstrate access/entitlement to the source and market connectivity. Alternately examples could arise where two or more entities could book the same BioEnergy source. Difficult or impossible to set out a prescriptive methodology that would deal with every eventuality. Methodology must be high-level and principle led. Practice will be determined by expert users. 20

21 Who should maintain and develop the Bioenergy / Biofuels classification framework? In the case of oil and minerals, industry standards are sponsored and maintained by industry or professional organizations, which also work to map their existing standards to the UNFC-2009, and to national reporting and regulatory disclosure agencies. The Petroleum Resource Management System (PRMS) is endorsed by the 5 major professional organizations [Society of Petroleum Engineers (SPE); Word Petroleum Council (WPC); American Association of Petroleum Geologists (AAPG); Society of Petroleum Evaluation Engineers (SPEE); Society of Exploration Geophysicists (SEG)] and maintained by SPE Oil & Gas Reserves Committee (OGRC). Bioenergy candidate organizations? Examples: Organisation Description Global Bioenergy Partnership (GBEP) World Bioenergy Association IRENA - International Renewable Energy Association Launched with support from G8 and G20, GBEP s purpose is to support wider, cost effective biomass and biofuels deployment (with particular focus on developing countries). It is a forum to develop effective policy frameworks to facilitate investment and promote project development and implementation. The purpose of WBA is to promote the increasing utilization of bioenergy globally in an efficient, sustainable, economic and environmentally friendly way. Members include national and regional bioenergy organizations, institutions, companies and individuals. Intergovernmental organisation that supports countries in their transition to a sustainable energy future, and serves as the principal platform for international cooperation, a centre of excellence, and a repository of policy, technology, resource and financial knowledge on renewable energy. 21

22 Key Questions / Issues Re-cap Can the UNFC-2009 be usefully applied to Bioenergy projects? Are the criteria for moving along the E- and F-axis clear? What is a useful project life time to apply? What uncertainties to be taken into account under the G-axis? Given the multiplicity of potential Bioenergy value chains are there any specific examples that raise unique methodological issues that need to be considered? Access and Entitlement to the Bioenergy source Achieving alignment on treatment of biomass sourced from commodity markets (spot / term contracts). Future owner for the Bioenergy Specification? 22

24 Can F4 / G4 Quantities be usefully defined? EFG 1-3 categorisation bounded by project criteria. How to evaluate a renewable resource outside of a project? Category E3F3G4? Resources are cumulative quantities of energy over a certain time period. What time period to use? G4 are estimated quantities associated with a potential Deposit ( exploration projects ). Is this classification applicable? Or should we apply G1 to G3 to reflect the level of confidence in the estimated quantities associated with a known Deposit? 24
