Interpretation of a three-dimensional (3-D) seismic dataset from offshore of Mauritania reveals a shear zone at the base of a partially developed slope failure. The shear zone is at a depth of ~220m below the seabed, immediately above a hydrate bottom simulating reflector (BSR). We propose that a paleo-gas accumulation trapped below hydrate was the primer for what would have been a substantial submarine slope failure of ~220m thickness, covering ~50km2. This is based on the following observations: (a) the shear surface is, at the level of seismic resolution, coincident with some present gas accumulations located immediately below sediment that hosts hydrate; (b) there are remnants of a more extensive paleo gas accumulation that would have generated sufficient buoyancy pressure for the shear surface to be critically stressed and therefore primed the failure; (c) seismic pipes are a common seismic feature within the studied succession but absent in the area of the shear zone, which supports the hypothesis that a high gas column could have existed. This is a rare example of a shear zone that did not lead to the complete development of a slope failure. It provides the first seismic evidence that the buoyancy effect of gas below the hydrate rather than the hydrate dissociation is also a viable mechanism for large-scale slope failures. © 2016.

The Energy Generation and Supply Knowledge Transfer Network has developed a free online Energy Funding Landscape Navigator which takes users through the energy funding landscape, providing clear guidance on the key public bodies and support mechanisms for UK energy projects. Users can search a live list of energy research, development, demonstration and deployment opportunities and can get help in finding the right partners to build project teams. Developed by the UK Energy Research Centre, the Navigator addresses feedback from the research, development, demonstration and deployment community, which indicated that the myriad of schemes to access public support for energy innovation was confusing and that opportunities were being missed. The Navigator is particularly valuable to smaller technology companies who struggle to keep up to speed with the myriad of support mechanisms in the UK. The Navigator also fulfils an important role to keep up to date with the evolution of the energy innovation landscape as the UK low-carbon energy strategy develops. For example, the Navigator was a central point of information for the energy community for tracking developments after the 2010 comprehensive spending review. Source

The UK energy technology innovation system (ETIS) has undergone wholesale remaking in recent years, in terms of its aims, funding and organisation. We analyse this process and distinguish between three phases since 2000: new beginnings, momentum building and urgency and review. Within an international trend to ETIS rebuilding, UK experience has been distinctive: from a low starting base in the early-2000s, to system remaking under a strong decarbonisation policy imperative in the late-2000s, to multiple and contested drivers in the early-2010s. Public funding levels have been erratic, with a rapid increase and a more recent decline. The private business sector has played a leading role in this remaking, and as this influence has grown, the role and style of energy innovation has shifted from long term niches to the shorter term mainstream. The UK ETIS suffers from persistent problems: fragmentation, low transparency and weak links to the research evidence base. © 2014 The Authors. Source

Environmental Innovation and Societal Transitions

This article focuses on the role of community leadership in the development of grassroots innovations. It asks: When community leaders initiate energy projects, what types of skills and knowledge practices do they utilise to nurture grassroots innovations? Grassroots innovations are usually driven by social and sustainability motives, and developed by civil society groups. Based on a mixed methods approach including research interviews and site visits, the article draws on previous literature on community leadership, grassroots innovations and niche literature. Community leadership is analysed via two in-depth community energy cases in the UK. Research findings show that community leadership can aid the development of grassroots innovations, which operate in niches and require nurturing. Community leadership benefits from being embedded into social networks, shared vision and decision making, but pre-existing skills and tacit knowledge also play a role. Community leaders can also assist niche building by working closely with intermediary actors. © 2016 The Author. Source

There is renewed interest in the role of supply diversity in promoting energy security. This paper explores ways of valuing diversity. A possible incentive mechanism for promoting diversity which takes account of underlying "disparities" between different technology options is developed. The mechanism provides a way of trading off cost and diversity and results in an "efficient" cost-diversity frontier by analogy with financial portfolio theory. If all technologies are believed to be equally disparate, the appropriate mechanism is a "levy" imposed on market share. If the technologies are not equally disparate, the levy needs to be adjusted by technology-specific multipliers that take account of levels of disparity and patterns of market share. The analysis is applied to two stylised situations. In the long-run equilibrium case, the implications of both different patterns of disparity and different values attached to diversity are investigated. The paper also explores the implications of applying such a mechanism to the current Great Britain electricity system. The implications in terms of financial flows, for both the market as a whole and for individual operators, are investigated. Finally, the appropriateness of such a mechanism in the light of other policy goals, and possible future research directions, is discussed. © 2010 Elsevier Ltd. Source
