Hydrogen

The use of hydrogen has been widely touted as having a key role to play in the energy networks of the future, featuring in the government’s 10 point plan and helping to shape Net-Zero documents. Therefore, this CPD seeks to highlight the benefits of hydrogen, assess the risks associated with its deployment and study its production and capabilities. The CPD will also highlight the political, social and technological reasons as to why hydrogen could be an ideal fit for the decarbonisation of our energy network.

BioLPG

This CPD shows the benefits of a transition from Oil and to a lesser extent LPG and BioLPG energy sources. This is particularly focused on hot water heating applications. A practical example of a modern dairy farm application was used to show the carbon savings of the proposed system. BioLPG has strong potential to decrease carbon emissions in buildings with poor to medium insulation. These buildings are often situated in rural areas of the country with limited access to alternative energy sources. Low-temperature system powered by hydrogen. This module explores some of the key factors that successfully decrease carbon emissions in Domestic hot water systems (DHW). The CPD is focused on a low-temperature system powered with Hydrogen blends. A practical example is utilised to further explain the benefits of such systems.

Seasonal Performance Factor (SPF) for Heat Pump Systems 

This CPD is based on the introduction and analysis of SPFs for commercial heat pump systems, solely supplying domestic hot water. It will look to introduce a new methodology for measuring the performance, as opposed to the measurements used today (SCOP, COP). The presentation will also cover a case study, where design SPFs have been calculated for a notional fast-food restaurant, based on a series of assumptions which allow for a logical simulation. 

Since the residential sector has set its own targets of electrifying heat and increasing the EPC band by 2030, the UK needs to focus on ways to decarbonise the commercial sector due to the increased difficulty, such as space constraints and differing demand profiles. Therefore, this presentation looks at introducing a low-carbon, renewable hot water system suitable for commercial applications.

Integrating Heat Pumps and Solar Thermal to satisfy the DHW needs of commercial applications

This system, comprising solely heat pumps and solar thermal tubes, will be analysed and compared against various already available system types to understand how each system type performed against a set of key metrics critical to ensure project feasibility (key metrics include: operating expenditure, capital expenditure, lifecycle costs, carbon production, seasonal performance factor and the primary energy

Sustainable Solutions: Retrofitting Heat Pumps into the Leisure Sector through CCA & SPF Analysis

This CPD is an expanded case study of retrofitting a heat pump system into the leisure sector. The building in question is a leisure centre that’s going through renovation and wanting to meet low GWP targets. The CPD also expands beyond a simple ‘design & build’ case study through exploring design considerations from a manufacturer's/supplier’s perspective as well as comparing various systems & options through analytical CCA & SPF studies.
