“…Perhaps the biggest technological barrier in Finland has been the lack of energy storage systems [29]. Nevertheless, high growth of newly introduced storage solutions in Germany shows very fast progress.…”

“…It appears rather likely that solutions of front-running markets will be introduced finally also in Finland, which leads to the fact that the problem is no longer a technological one, but rather a problem of inefficient markets. Grids and grid monopoly have most often been mentioned as technological problems [28,29]. There are concerns about possible impacts of distributed power on the electrical grid, the lack of standard procedures for grid connections, and issues with metering [29].…”

“…Grids and grid monopoly have most often been mentioned as technological problems [28,29]. There are concerns about possible impacts of distributed power on the electrical grid, the lack of standard procedures for grid connections, and issues with metering [29]. Grids also need to be made easier for small-scale producers to connect to and producers also should receive better compensation, for instance an hourly based net metering.…”

“…Cost comparisons with the conventional energy system and competitiveness are no doubt among the biggest barriers overall in Finland, both for utilities and for consumers [28,29]. From the perspective of utilities, the incumbent energy companies feel that an energy system that is based on higher shares of renewables is too expensive; without a well-functioning energy storage system intermittent renewables are expected to need a back-up system and incumbent energy companies still expect that they have to maintain that infrastructure and manage the costs.…”

“…Further, there is a need in Finland to not only dispel myths surrounding solar PV, but to begin discourse which will ultimately make the social and economic climate around all forms of renewable energy more favourable. Recent studies in Finland [29,30] have already advanced the discussion about distributed generation of renewable energy in terms of barriers, key drivers, benefits and the implementation of policies that would support future development.…”

The Role of Solar Photovoltaics and Energy Storage Solutions in a 100% Renewable Energy System for Finland in 2050

There are several barriers to achieving an energy system based entirely on renewable energy (RE) in Finland, not the least of which is doubt that high capacities of solar photovoltaics (PV) can be feasible due to long, cold and dark Finnish winters. Technologically, several energy storage options can facilitate high penetrations of solar PV and other variable forms of RE. These options include electric and thermal storage systems in addition to a robust role of Power-to-Gas technology. In an EnergyPLAN simulation of the Finnish energy system for 2050, approximately 45% of electricity produced from solar PV was used directly over the course of the year, which shows the relevance of storage. In terms of public policy, several mechanisms are available to promote various forms of RE. However, many of these are contested in Finland by actors with vested interests in maintaining the status quo rather than by those without confidence in RE conversion or storage technologies. These vested interests must be overcome before a zero fossil carbon future can begin. The results of this study provides insights into how higher capacities of solar PV can be effectively promoted and managed at high latitudes, both north and south.

Small‐scale horizontal axis wind‐turbines (SHAWTs) are acquiring relevance within the regulatory policies of the wind sector aiming at net‐zero emissions, while reducing visual and environmental impact by means of distributed grids. SHAWTs operate transitionally, at Reynolds numbers that fall between . Furthermore, environmental turbulence and roughness affect the energetic outcome of the turbines. In this study, the combined effect of turbulence and roughness is analysed via wind tunnel experiments upon a transitionally operating NACA0021 airfoil. The combined effects cause a negative synergy, inducing higher drops in lift and efficiency values than when considering the perturbing agents individually. Besides, such losses are Reynolds‐dependent, with higher numbers increasing the difference between clean and real configurations, reaching efficiency decrements above 60% in the worst‐case scenario.Thus, these experimental measurements are employed for obtaining the power curves and estimating the annual energy production (AEP) of a 7.8‐kW‐rated SHAWT design by means of a BEM code. The simulations show a worst‐case scenario in which the AEP reduces above 70% when compared to the baseline configuration, with such a loss getting attenuated when a pitch‐regulated control is assumed. These results highlight the relevance of performing tests that consider the joint effect of turbulence and roughness.
