Microgeneration - producing energy for the home, in the home - is a substantial improvement over the current centralised and detached energy model employed the world over. Domestic Microgeneration is the first in-depth reference work for this exciting and emerging field of energy generation. It provides detailed reviews of ten state-of-the-art technologies: including solar PV and thermal, micro-CHP and heat pumps; and considers them within the wider context of the home in which they are installed and the way that they are operated. Alongside the many successes, this book highlights the common pitfalls that beset the industry. It offers best-practice guidance on how they can be avoided by considering the complex linkages between technology, user, installer and government. This interdisciplinary work draws together the social, economic, political and environmental aspects of this very diverse energy ‘genre’ into a single must-have reference for academics and students of sustainability and energy related subjects, industry professionals, policy makers and the growing number of energy-literate householders who are looking for ways to minimise their environmental footprint and their energy bills with microgeneration.

Staffell I, Matian M, Brett DJL, et al., 2015, Fuel cell micro-CHP, Domestic Microgeneration: Renewable and Distributed Energy Technologies, Policies and Economics, Pages: 219-251, ISBN: 9780415810418
Fuel cells operate with a fundamentally different mechanism to CHP engines. They electrochemically convert the chemical energy in a fuel directly into electrical current, rather than combusting it to produce heat, which must then be converted into motion and then to electricity. A simplified view of a fuel cell is a cross between a battery (chemical energy converted directly into electrical energy) and a heat engine (a continuously fuelled, air-breathing device); and so fuel cells are sometimes thought of as ‘electrochemical engines’ or ‘continuously fuelled batteries’ [1].

This chapter explores the use of mathematical modelling for the simulation and optimisation of microgeneration technologies. In the case of simulation this is to explore the performance of microgeneration technologies against user-defined performance criteria. In the case of optimisation, this is to identify an optimum solution against user-defined constraints. The discussion begins at the scale of modelling individual components within a microgeneration system and the operation of these systems within the home, then moves up to country-scale modelling of how microgeneration acts within the whole energy system and its impacts on national energy consumption and carbon emissions.

Energy systems models are important methods used to generate a range of insight and analysis on the supply and demand of energy. Developed over the second half of the twentieth century, they are now seeing increased relevance in the face of stringent climate policy, energy security and economic development concerns, and increasing challenges due to the changing nature of the twenty-first century energy system. In this paper, we look particularly at models relevant to national and international energy policy, grouping them into four categories: energy systems optimization models, energy systems simulation models, power systems and electricity market models, and qualitative and mixed-methods scenarios. We examine four challenges they face and the efforts being taken to address them: (1) resolving time and space, (2) balancing uncertainty and transparency, (3) addressing the growing complexity of the energy system, and (4) integrating human behavior and social risks and opportunities. In discussing these challenges, we present possible avenues for future research and make recommendations to ensure the continued relevance for energy systems models as important sources of information for policy-making.

The debate on low carbon heat in Europe has become focused on a narrow range of technological options, largely neglecting hydrogen and fuel cell technologies. Yet commercial ventures installing fuel cell CHP and establishing pilot programmes for injecting hydrogen into natural gas grids have already emerged. Furthermore, recent research suggests that the potential for hydrogen and fuel cells may have been overlooked, suggesting a gap between the scientific evidence base and policy direction. Thus there is a clear need-also recognised by government-for a clear assessment of the evidence on the potential for hydrogen and fuel cells in meeting the goals of European heat policy: The provision of secure, affordable, low-carbon heat. The UK H2FC Hub, which represents the UK hydrogen and fuel cell research community, is launching a White Paper in May 2014 to set out the potential for hydrogen and fuel cells to contribute to affordable, secure, low-carbon heating in the future. This paper will provide an authoritative, accessible, detailed account that is specifically targeted at policymakers and other stakeholders. It will bring together the evidence on the technical, economic, market, system and policy issues surrounding hydrogen and fuel cell heat.

Zhang D, Samsatli NJ, Hawkes AD, et al., 2012, Fair electricity transfer price and unit capacity selection for microgrids, Energy Economics, Vol: In Press, ISSN: 0140-9883
Microgrids are defined as an area of electricity distribution network that can operate autonomously from the rest of the network. In order to achieve the best economic outcomes, the participants in a microgrid can benefit from cooperation in microgrid design and operation. In this paper, a mathematical programming formulation is presented for fair, optimised cost distribution amongst participants in a general microgrid. The proposed formulation is based on the Game-theory Nash bargaining solution approach for finding optimal multi-partner cost levels subject to given upper bounds on the equivalent annual costs. The microgrid planning problem concerning the fair electricity transfer price and unit capacity selection is first formulated as a mixed integer non-linear programming model. Then, a separable programming approach is applied to reform the resulting mixed integer non-linear programming model to a mixed integer linear programming form. The model is applied to a case study with a microgrid involving five participants.

Heat pumps are a promising technology for heating (and cooling) domestic buildings that provide exceptionally high efficiencies compared with fossil fuel combustion. There are in the region of a billion heat pumps in use world-wide, but despite their maturity they are a relatively new technology to many regions. This article gives an overview of the state-of-the-art technologies and the practical issues faced when installing and operating them. It focuses on the performance obtained in real-world operation, surveying the published efficiency figures for hundreds of air source and ground source heat pumps (ASHP and GSHP), and presenting a method to relate these to results from recent UK and German field trials. It also covers commercial aspects of the technologies, the typical savings in primary energy usage, carbon dioxide emissions abatement that can be realised, and wider implications of their uptake.
