The Impact

Renewable energy sources (RES) play a critical role in the low-carbon energy transition. Although there is quite an abundant literature on the barriers to RES, the analysis of the electricity generation overcapacity as a barrier to further RES penetration has received scant attention. This paper tries to cover this gap. Its aim is to analyse the causes and consequences of overcapacity, with a special focus on the impact on RES deployment, using Spain as a case study. It also analyses the policies which may mitigate this problem in both the short and the longer terms.

The Impact

The ongoing deployment of renewable energy sources (RES) calls for an enhanced integration of RES into energy markets, accompanied by a new set of regulations. In Germany, for instance, the feed-in tariff legislation for renewables has been successively replaced by first optional and then obligatory marketing of RES on competitive wholesale markets. This paper introduces an agent-based model that allows studying the impact of changing energy policy instruments on the economic performance of RES operators and marketers. The model structure, its components, and linkages are presented in detail; an additional case study demonstrates the capability of our sociotechnical model. We find that changes in the political framework cannot be mapped directly to RES operators as behaviour of intermediary market actors has to be considered as well. Characteristics and strategies of intermediaries are thus an important factor for successful RES marketing and further deployment. It is shown that the model is able to assess the emergence and stability of market niches.

The Impact

This paper deals with the general problem of utilizing of renewable energy sources to generate electric energy. Recent advances in renewable energy power generation technologies, e.g., wind and photovoltaic (PV) technologies, have led to increased interest in the application of these generation devices as distributed generation (DG) units. This paper presents the results of an investigation into possible improvements in the system voltage profile and reduction of system losses when adding wind power DG (wind-DG) to a distribution system. Simulation results are given for a case study, and these show that properly sized wind DGs, placed at carefully selected sites near key distribution substations, could be very effective in improving the distribution system voltage profile and reducing power losses, and hence could  improve the effective capacity of the system.

The Impact

Energy systems are undergoing a profound transition worldwide, substituting nuclear and thermal power with intermittent renewable energy sources (RES), creating discrepancies between the production and consumption of electricity and increasing their dependence on greenhouse gas (GHG) intensive imports from neighboring energy systems. In this study, we analyze the concurrent electrification of the mobility sector and investigate the impact of electric vehicles (EVs) on energy systems with a large share of renewable energy sources. In particular, we build an optimization framework to assess how Evs could compete and interplay with other energy storage technologies to minimize GHG-intensive electricity imports, leveraging the installed Swiss reservoir and pumped hydropower plants (PHS) as examples. Controlling bidirectional EVs or reservoirs shows potential to decrease imported emissions by 33–40%, and 60% can be reached if they are controlled simultaneously and with the support of PHS facilities when solar PV panels produce a large share of electricity. However, even if vehicle-to-grid (V2G) can support the energy transition, we find that its benefits will reach their full potential well before EVs penetrate the mobility sector to a large extent and that EVs only contribute marginally to long-term energy storage. Hence, even with a widespread adoption of EVs, we cannot expect V2G to single-handedly solve the growing mismatch problem between the production and consumption of electricity.

This research analyses straw degradation inside straw bale walls in the region and develops the prediction of degradation inside straw bale walls. The results show that the straw inside straw bale walls have no serious concerns of degradation in the high hygrothermal environment in the region with only moderate concerns of degradation in the area 2–3 cm deep behind the lime render. The onsite investigations indicate that the degradation isopleth model can only predict straw conditions behind the rendering layer, whereas the isothermal model fits the complete situation inside straw bale walls. This research develops the models for predicting straw degradation levels inside a straw bale building in a warm (humid) continental climate. The impact of this research will help the growth of low carbon energy efficient straw bale construction with confidence pertaining to its long-term durability characteristics both in the region and regions sharing similar climatic features globally.

Change Mitigation

The paper deals with the exposition of the main barriers and drivers of renewable energy usage in rural communities. Climate change mitigation is causing governments, policymakers, and international organizations worldwide to embark on policies, leading to increased use of renewable energy sources and improvement of energy efficiency. Climate change mitigation actions, including the Green Deal strategy in the EU, require satisfying the expanding energy demand and complying with the environmental restrictions. At the same time, the prevailing market structure and infrastructure relevant to the energy systems are undergoing a crucial transformation. Specifically, there has been a shift from centralized to more decentralized and interactive energy systems that are accompanied by a low-carbon energy transition. Smart Grid technology and other innovations in the area of renewable energy microgeneration technologies have enabled changes in terms of the roles of energy users: they can act as prosumers that are producing and consuming energy at the same time. Renewable energy generation that is allowing for deeper involvement of the citizens may render higher social acceptance, which, in turn, fuels the low-carbon energy transition. The collective energy prosumption in the form of energy cooperatives has become a widespread form of renewable energy initiatives in rural communities. Even though renewable energy consumption provides a lot of benefits and opportunities for rural communities, the fast penetration of renewables and energy prosumption encounter several important barriers in the rural areas. This paper analyses the main barriers and drivers of renewable energy initiatives in rural areas and provides policy implications for the low-carbon energy transition in rural areas.

Goals And Objectives

The aim of the work is to develop recommendations for Ukraine on setting long-term integrated climate and energy goals and identifying ways to achieve them. The preconditions, main goals and objectives of the European Green Deal, which was presented by the European Commission in December 2019, are analyzed. The European Green Deal is a comprehensive strategy for the transition to a sustainable economy, clean energy and climate neutrality, i.e., zero greenhouse gas emissions, in Europe by 2050. The adoption of this Deal was preceded by several stages of a coherent EU policy in the relevant sectors. Possibilities for renewable energy development within the framework of the European Green Deal are considered. It is determined that preference is given to the production of green electricity, mobilization of the potential of offshore renewable energy, production of biogas and biofuels from biomass of agricultural origin, sustainable use of low-carbon and renewable fuels, including biomass and hydrogen, in hard-to-electricity sectors. In Ukraine, the document that is closest by its contents to the European Green Deal is the draft Concept of green energy transition until 2050 presented in January 2020. The draft Concept states the goal of achieving 70% of renewable energy sources in electricity generation by 2050 and the climate-neutral economy of Ukraine by 2070. It is recommended that this document should be finalized and adopted formally as soon as possible.

Low Carbon Energy

<p>To meet global commitments to reach net-zero carbon emissions by 2050, the energy mix must reduce emissions from fossil fuels and transition to low carbon energy sources.  Hydrogen can support this transition by replacing natural gas for heat and power generation, decarbonising transport, and facilitating increased renewable energy by acting as an energy store to balance supply and demand. For the deployment at scale of green hydrogen (produced from renewables) and blue hydrogen (produced from steam reformation of methane) storage at different scales will be required, depending on the supply and demand scenarios. Production of blue hydrogen generates CO<sub>2</sub> as a by-product and requires carbon capture and storage (CCS) for carbon emission mitigation.  Near-future blue hydrogen production projects, such as the Acorn project located in Scotland, could require hydrogen storage alongside large-scale CO<sub>2 </sub>storage. Green hydrogen storage projects, such as renewable energy storage in rural areas e.g. Orkney in Scotland, will require smaller and more flexible low investment hydrogen storage sites. Our research shows that the required capacity can exist as engineered geological storage reservoirs onshore and offshore UK. We will give an overview of the hydrogen capacity required for the energy transition and assess the associated scales of storage required, where geological storage in porous media will compete with salt cavern storage as well as surface storage such as line packing or tanks.</p><p>We will discuss the key aspects and results of subsurface hydrogen storage in porous rocks including the potential reactivity of the brine / hydrogen / rock system along with the efficiency of multiple cycles of hydrogen injection and withdrawal through cushion gasses in porous rocks. We will also discuss societal views on hydrogen storage, exploring how geological hydrogen storage is positioned within the wider context of how hydrogen is produced, and what the place of hydrogen is in a low-carbon society. Based on what some of the key opinion-shapers are saying already, the key considerations for public and stakeholder opinion are less likely to be around risk perception and safety of hydrogen, but focussed on questions like ‘who benefits?’ ‘why do we need hydrogen in a low-carbon society?’ and ‘how can we do this in the public interest and not for the profits of private companies?’</p><p>We conclude that underground hydrogen storage in porous rocks can be an essential contributor to the low carbon energy transition.</p>
