Requirements for minerals and metals for 100% renewable scenarios

© The Author(s) 2019. This chapter explores the magnitude of the changes in patterns of material use that will be associated with the increasing deployment of renewable energy and discusses the implications for sustainable development. In particular, this chapter focuses on the increased use of lithium and cobalt, metals which are used extensively in battery technologies, and silver used in solar cells. Consistent with the strong growth in renewable energy and electrification of the transport system required in a 1.5°C scenario, the material requirements also rise dramatically, particularly for cobalt and lithium. Scenarios developed for this study show that increasing recycling rates and material efficiency can significantly reduce primary demand for metals

Achieving Very High PV Penetration

This article argues that optimally deployed intermittency solutions could affordably transform solar power generation into the firm power delivery system modern economies require, thereby enabling very high solar penetration and the displacement conventional power generation. The optimal deployment of these high‐penetration enabling solutions imply the existence of a healthy power grid, and therefore imply a central role for utilities and grid operators. This article also argues that a value‐based electricity compensation mechanism, recognizing the multifaceted, penetration‐dependent value and cost of solar energy, and capable of shaping consumption patterns to optimally match resource and demand, would be an effective vehicle to enable high solar penetration and deliver affordable firm power generation

Public perception of sustainable energy innovation: A case study from Tilos, Greece

Renewable and smart grid technologies play a key role in delivering a sustainable energy future for non-interconnected islands. In this context, societal acceptance of proposed interventions manifests itself as a major determinant of planned transitions. With extant scholarship on public acceptability of sustainable energy technologies focusing on local opposition to wind farms, this paper presents timely survey data from the island of Tilos to provide a better understanding of energy-users’ perceptions vis-à-vis novel smart island proposals. Against stultifying narratives highlighting the lack of community acceptance for local interventions, we uncover: a) the widespread acceptance of sustainable and smart energy solutions, and b) the willingness of a large proportion of locals to play their part, as engaged energy prosumers, in a green energy transition. In turn, these findings form the basis for future academic and technical interventions on the island, and inform broader conclusions on public engagement around energy

Industry-led awards 2018. Marine Institute Grant Awards in Support of the Marine Economy.

Innovation 2020, Ireland’s strategy for research and development, science and technology states that despite the importance of research and innovation for firms, firms under-invest in research. Therefore there is a strong case for the state to encourage firms to undertake research by providing co-investment. However, this investment must be targeted at areas of commercial opportunity that are strategically important. This is the underpinning rationale of Research Prioritisation (2018-2023), which identifies 6 Themes and 14 Priority Areas that present particular market opportunities for Ireland. The first goal of Harnessing Our Ocean Wealth is “A Thriving Maritime Economy”, which focuses on the marine opportunities to achieve economic recovery with socially inclusive and sustainable growth. The Development Task Force Report developed a strategic framework identifying three interventions to drive growth across five thematic areas and create economic growth opportunities for the marine sector. In May 2018, the Marine Institute launched the Industry-Led Call, designed to provide funding for SMEs to raise the maturity levels for their research theme across these three dimensions (human capacity, infrastructure and networks & relationships). The call aims to fulfil national strategic objectives as follows: National Marine Research and Innovation Strategy 2017-2021 - Implementation of Action 8 Increase opportunities for SMEs to participate in marine research. Innovation 2020 - Action point 2.4 Optimising Enterprise RDI Supports. The funding aims to: Support research and innovation costs for the development of innovative technologies, products and services from existing or new marine-based business. Help marine companies to develop capacity, capability and their networks & relationships. Support “novel” marine research that has not previously received funding to create new knowledge or a new product, process or service or to substantially improve existing products, processes or services.Marine Institut

Hybrid Power System Options for Off-Grid Rural Electrification in Northern Kenya

For domestic consumers in the rural areas of northern Kenya, as in other developing countries, the typical source of electrical supply is diesel generators. However, diesel generators are associated with both CO2 emissions, which adversely affect the environment and increase diesel fuel prices, which inflate the prices of consumer goods. The Kenya government has taken steps towards addressing this issue by proposing The Hybrid Mini-Grid Project, which involves the installation of 3 MW of wind and solar energy systems in facilities with existing diesel generators. However, this project has not yet been implemented. As a contribution to this effort, this study proposes, simulates and analyzes five different configurations of hybrid energy systems incorporating wind energy, solar energy and battery storage to replace the stand-alone diesel power systems servicing six remote villages in northern Kenya. If implemented, the systems proposed here would reduce Kenya’s dependency on diesel fuel, leading to reductions in its carbon footprint. This analysis confirms the feasibility of these hybrid systems with many configurations being profitable. A Multi-Attribute Trade-Off Analysis is employed to determine the best hybrid system configuration option that would reduce diesel fuel consumption and jointly minimize CO2 emissions and net present cost. This analysis determined that a wind-diesel-battery configuration consisting of two 500 kW turbines, 1200 kW diesel capacity and 95,040 Ah battery capacity is the best option to replace a 3200 kW stand-alone diesel system providing electricity to a village with a peak demand of 839 kW. It has the potential to reduce diesel fuel consumption and CO2 emissions by up to 98.8%

Microgrids:experiences, barriers and success factors

Although microgrids have been researched for over a decade and recognized for their multitude of benefits to improve power reliability, security, sustainability, and decrease power costs for the consumer, they have still not reached rapid commercial growth. The main aim of this research is to identify the common barriers and ultimate success factors to implementing a microgrid in the real world. We found that microgrids vary significantly depending on location, components, and optimization goals, which cause them to experience different types of challenges and barriers. However, the most common barriers were identified and grouped into four categories: technical, regulatory, financial, and stakeholder, based on the literature and overlying patterns recognized amongst the thirteen case studies. The most common technical barriers include problems with technology components, dual-mode switching from grid-connected to island mode, power quality and control, and protection issues. There is extensive research on how to overcome these issues, so technical solutions are becoming available yet case specific. Regulatory barriers exist due to interconnection rules with the main grid and the prohibition of bi-directional power flow and local power trading between microgrid and the main network. The latter issue is the barrier experienced most often and has only recently been addressed, so solutions need further research. The main financial barrier is still the burden of high investment and replacement costs of the microgrid. This can be resolved with proper market support in the short term and might naturally resolve itself through learning over the long run. Lastly, stakeholder barriers include issues with conflicting self-interest and trust, and having the expertise to manage operations. These stakeholder barriers are not yet addressed in the literature and need to be further researched

Induced innovation in clean energy technologies from foreign environmental policy stringency?

In this paper, we re-conceptualize the meaning of policy-induced innovations in clean technologies by taking a cross-border approach. Previously, empirical research has shown how domestic climate and environmental policies induce firms in the same country to innovate in clean and environmental technologies. This phenomenon has become known as the Porter Hypothesis. However, most research focuses strictly on domestic inducement effects and, if foreign effects are accounted for, they are assumed to be either “knowledge” or “technology” spillovers. We, however, propose that policy spillovers might also induce innovations in other countries. In order to test this hypothesis, we construct a “foreign” environmental policy stringency proxy. This proxy is used as the main explanatory variable, with the outcome variable clean technologies, defined here as all renewable energy technologies as well as electrical energy storage, because these technologies are predominantly defined within the scope of climate and environmental policies as necessary to combat climate change and set forth as paramount to stemming pollutant causing climate change in the United Nations Framework Convention on Climate Change founding documents. Our results show that foreign environmental policy stringency does, indeed, induce clean-technology innovation at home, but this effect varies with different lag structures in our three models
