SGI-Imperial Aims CHALLENGES New sources of natural gas R AS MA G E R U FUT Climate change and carbon budget KET • Launched in May 2014. Unique academic-industry partnership (Shell and Imperial College London) • Examine the environmental, economic and technological role of natural gas in the global energy landscape. • Address the global challenge of how industry can mitigate climate change. • Define the technologies and develop energy systems models that could explore the role of gas in the energy landscape. • Help to advance technology roadmaps to support future R&D investment decisions.
What do we do? I. Deliver evidence based white papers that inform the debate around the role of natural gas. II. Developing a methane research programme III. Developing a novel Integrated Assessment Simulation tool (MUSE) to analyse the global energy system and land use, and the role of technologies within it.
The SGI White Paper Series • Evidence-based reviews targeted at a global audience of policy/decision makers and industry • Provide clarity to contentious topics in the energy sector and help inform debate around natural gas. • A systematic review of the contemporary evidence base and primary analysis. • Each paper begins with a published scoping note. • Reviewed by an international expert group. • Published online with a short two-page summary. www. sustainablegasinstitute. org/white_paper_series/

Integrated Assessment Models ●Researchers have relied heavily on IAMs to explore decarbonisation pathways IPCC 5 th Assessment Report - 1, 184 scenarios were produced from 31 whole system models - Quantitative basis for working group 3 conclusions (mitigation) ●The ultimate goal of the process is scientific credibility, public acceptance, and political and legal viability. ●Research community improving how it reports and handles the wide range of uncertainty from IAM‐based calculations Source: Fuss et al (2014) Betting on negative emissions. Nature Climate Change 4, 850– 853
MUSE: why and how? Why a new model? Among the available models, there is often lack of clarity on the input assumptions and flexibility q Bringing engineering reality to systems-level modelling q Better insight for the energy industry (e. g. O&G on upstream opportunities) q The need for transparency in methods, assumptions and results How? o Simulation not optimisation o Flexible sector modules – entirely new approach o Imperfect foresight – simulate real decision making o Open-access, clear communication, credibility Applications: Ø Understanding the role of gas in low carbon energy systems Ø R&D prioritisation of value and role of technologies Ø Strategy and business model development against a variety of scenarios Ø Climate change mitigation pathways assessment (i. e. long-term)

Supply: Gas module Module’s aim • Build future supply curves for natural gas by simulating demand-driven investor preferences (the development new fields). • Balance technological detail with simplicity & scalability: work on field level, with major cost categories included explicitly. • For each region, use industrial data (Rystad) to determine simple correlations between expenditure and lifecycle production
Supply: Gas module Ranking gas fields in terms of their unit long-run-marginalcost (lrmcn, j, r, t).

Demand: Agriculture & Land Use Module Challenges: • Lack of a robust procedure to establish a relationship between agricultural technological diffusion and their impacts on agricultural energy use, commodity productivity and land use impact. • Land is a limited resource • Bioenergy and food competition Methodology: • Two-step simulation approach to model investment decisions and operating strategies and represent real investors' behaviour in the agriculture sector • The model represents technologies in the agricultural sector as mechanisation levels • Provides bioenergy constraints
Technology representation The level of agricultural development in a region can be seen by analysing the cluster of agricultural production and energy use per land unit in every country. • 180 -country sample • Multivariate statistical analysis. Cluster analysis procedure (k-means) • Three final major clusters were observed In line with IRENA and FAO, Mechanisation levels have been characterised as follows: I. Traditional II. Transitional III. Modern
