Data Science LeadKiwa Uk 2019 - Dec 2020Cheltenham, Gloucestershire, United KingdomCollection and analysis of data, quality assurance and collaboration with stakeholders for the Hy4Heat programme, of which Kiwa are technical lead (2018-2020). Part of this is a safety assessment of using hydrogen gas in domestic properties, which required knowledge of the frequencies of different types of gas escapes and how gas accumulates inside a property.I designed and implemented a web-based system to collect data from First Call Operatives (FCOs) during emergency gas-escape callouts. Working with Gas Distribution Network Operators (GDNOs), I deployed the system and conducted face-to-face and video training sessions. I analysed the surveys using both expert-system and machine learning models, and devised and managed the process for quality assurance of the models using a team of experts, whilst providing regular dashboards to stakeholders.I also programmed a system to extract and compare gas accumulation data with theoretical models of gas dispersion, both for technical review and quality assurance of the contractor-collected data and for the evaluation of the appropriateness of the theoretical models.Modelling of a wind turbine, hydrogen electrolyser and storage system for Project Methilltoune (pub. Jan 2020), the feasibility design for SGN’s H100 Fife project. A key challenge was matching the variable generation from the wind turbine with the variable demand of the distribution network. Various electrolysers were evaluated, however each of these had their own constraints. I designed a theoretical model of each electrolyser and used this to model various generation, demand and storage scenarios in terms of efficiency and cost.As a part of SGN’s H100 programme, I designed and implemented the data acquisition system for a set of gas chromatographs and led the data analysis of a series of laboratory trials to demonstrate the effectiveness of odourant as a means of detecting hydrogen gas escapes (2019). -
Consultancy Team LeaderKiwa Uk 2016 - 2019Cheltenham, England, United KingdomI became Consultancy Team Lead at Kiwa Gastec in 2016.From 2017 – 2018, I designed the data collection and processing system for a series of hydrogen feasibility & practical safety trials in various domestic settings. I also led on several phases of the field work, data analysis and reporting. My data processing system, written using Numpy, Scipy & Pandas, took data exports from high-speed voltage recorders (10,000 Hz) and applied various filters (low-pass, custom Fourier, median filters, etc.), before identifying and quantifying sudden changes; data analysis was with Jupyter Notebooks and graphs were generated using Matplotlib. Additional graphs of low-speed incoming data were displayed on a low-powered laptop using a customisable Excel dashboard.In 2018, I was a Lead Assessor for BEIS for applications to the Energy Entrepreneurs Fund: phase 7.I was project manager for Phase II of the BEIS Biomass Boiler Field Trial (2016-2018), studying 67 domestic and non-domestic biomass heating systems. I am lead author on the report, and led the detailed analysis of the performance of the systems, including the effects of thermal stores and controls. I made intervention visits at domestic and commercial sites (space and water heating), and carried out performance testing at a site with several kilometres of underground heat main and many plant rooms. In 2017, I chaired two stakeholder engagement days. The attendees were from industry, trade bodies, academia and government. Kiwa’s task was to present interim findings and gather feedback from those present. As chair, I ensured all the attendees were able to comment on the findings, but also had to clearly define the boundaries and time limits around discussions, to ensure all attendees were fairly represented. I also then led an analysis of the feedback gathered to determine if the project plan should be altered as a result.

Senior ConsultantKiwa Uk 2015 - 2016Cheltenham, United KingdomI became a Lead Verifier for the EU Emissions Trading Scheme Phase 3 (2015 ongoing), undertaking audit visits to industrial sites and verifying the application of mass-balance measurement systems for carbon emissions. Audits are either carried out as a sole Lead Verifier, or leading a team of Verifiers. In 2016, I led a team of independent QA reviewers for the BEIS field trial of non-domestic Renewable Heat Incentive ground-source and water-source heat pumps.I am also a member of the Kiwa internal audit team, as a part of our testing laboratory accreditation under ISO 17025.

Energy ConsultantKiwa Uk 2010 - 2015Cheltenham, UkI was a data analyst in the EST Heat Pump Field Trial (2013) and more recently led the analysis and authored reports in two heat pump field trials for manufacturers. A key objective was independently assessing the energy efficiency of the product at different system boundaries (according to the SEPEMO methodology).In 2015, I managed an expert investigation into boiler performance for a local authority, visiting 15 sites were operated by a mix of personnel with differing technical knowledge, from caretaker to building services manager. Stakeholder appetite to the investigation varied and during the short site visits I had to quickly build a level of trust with them to enable sufficient data to be collected and technical drawings of the heating system to be made. I then had to build on knowledge from two technical experts and summarise the themes of performance and health & safety issues observed at the sites in a report for the client.Also in 2015, I worked in a consortium of experts providing technical advice to Ofgem around the use of blended virgin and waste biomass fuels. Regular telephone conferences and exchange of comments on SharePoint were used to ensure all experts agreed with the technical output of the final report.I led the analysis and co-authored the report on a review of gas and electricity data from over 1,000 domestic properties in a trial of smart meters for a large utility company (2011–2012). Key achievements included quantifying the energy performance of the properties and identifying those at which energy saving measures could be made, ranging from controls adjustments, to retrofit of newer heating appliances and improved insulation.I performed practical and paper-based reviews of the performance of energy saving devices for manufacturers (2010–2012). These included advanced heating controls, central heating system debris filters, and water restriction devices, including one for the Carbon Emissions Reduction Scheme (CERT).
