Development of cradle-to-gate, ex-ante life cycle assessment model to quantify emissions from a new generation of bio-energy carbon capture and sequestration/utilisation projects.Key characteristics of analysis include:- Highly detailed inventory of emissions sources, consistent and surpassing requirements set by the ISCC+, and RED II.- Application of completed LCA model to generate a marginal abatement cost curve (MACC) for 40+ options for mitigating GHG emissions from the project, ranging from measures to enhance soil carbon accumulation, to ensuring elimination of fugitive methane, to minimising nitrous oxide emission from soils and many more.- Exploration of novel methods of valorising products of anerobic digestion, including the production of bio-hydrogen, bio-syngas, and pathways for the production of sustainable aviation fuel (SAF) cutting edge fischer-tropsch processes.

Guildford, England, United Kingdom

Part time position assisting in RHI related responsibilities that are outlined in full time role below. Position held while colleague was on leave due to an injury.Additionally, responsibilities included review and development of novel life cycle analysis model for greenhouse gas emissions for prospective biogas sites being developed as part of a bioenergy carbon sequestration scheme.

Guildford, England, United Kingdom

Principal responsibilities included:- Jointly responsible for quarterly renewable heat incentive (RHI) submissions for thirteen UK biogas sites, totaling to ~£40 million per year. Key tasks included development of macro enabled excel spreadsheet with capability to automate aggregation and interpretation of data from online portals of various formats. Responsible for preparation and checking of submissions. Responsible for RHI scheme administration and annual site audits. Responsible for forecasting of site greenhouse gas emissions performance.- Lead design and implementation of a SQL based solution (OSI PI) to deliver live telemetry data from site PLCs to a centralized database. Designed suite of online visualizations (dashboards) of live data to support operations teams in performance monitoring and maintenance of site equipment.- Development of PowerBI based operations reports for thirteen UK biogas facilities. Reports were driven using PowerQuery to automate the aggregation, data cleansing and analysis of site data entered manually by site staff on to Microsoft sharepoint sheets.

Leeds, United Kingdom

Developed a novel model combining an international Multi-Regional Environmentally-Extended Input-Output (MRIO) model with internationally available household expenditure data. The model estimated carbon distributions ensuing directly and indirectly from household expenditures, thus providing evidence for inequality in emissions as well as economic purchasing power, disaggregated by expenditure categories.

Bristol, United Kingdom

Responsibilities included:- Evaluating key drivers of the uptake of low carbon products and driving organisational behaviour change towards more energy-conscious and energy-efficient decision-making as part of DECC's what works project.- Updating DECC's Renewable Energy Planning Database (REPD), as well as developing existing web-scraping and geo-spatial information resources.

Norwich

Principal responsibilities to develop and maintain energy systems and other kinds of models that provide support quantitative analytical support to Cornwall Energy’s research projects.Lead the development of a replacement of the hedging model used by Ofgem in their monthly Supplier Market Indicator (SMI) reports.Lead development of project to analyse quantitative trends in UK domestic tariffs amongst the big six and independent suppliers.

Leeds, United Kingdom

Developed of a model of the UK electricity system, complete with technological and economic forecasts until the year 2050. This model was used to examine how the role subtle design choices in an energy systems model could influence results.Publications: Title: Energy Model, Boundary Object and Societal Lens: 35 years of the MARKAL model in the UKJournal: Energy Research & Social ScienceAuthors: Talyor, P.; McDonald, W.; Upham, P.; Christopherson, D.
