Over the lifetime of a wind turbine, operation and maintenance costs represent 25% of total levelised cost per kWh produced. The majority of these costs are attributed to the wind turbine’s blades, yet current methods of inspecting these blades are outdated and inefficient. Blade inspection procedures still largely relies on qualified inspectors roping down each blade to manually inspect for any flaws or defects present on the blade. This is clearly a very hazardous, time-consuming (5 hours), and expensive method (€1500). Other less used methods of blade inspection include capturing blade images from ground cameras and manual review by experts. However, poor image quality and strong backlight leaves many blade flaws undetected. Unmanned Aerial Vehicles (UAVs) are now being used to take pictures of the blades from much closer up. Current UAV's however require dedicated experts for both flight control as well as image processing, analysis, and fault detection. Pro-Drone's integrated WindDrone Zenith’s solution is a breakthrough solution providing enabling 3-blade inspection in a single flight. Our technology solution is fully equipped with highly accurate inspection equipment hardware coupled with smart software. The software allows the UAV to be fly autonomously, avoid collisions, automatically detect any faults, and generate reports for the customer on each wind turbine inspected. Machine learning algorithms are used to continuously improve automated fault detection based on a growing database of captured images and their analysis. Our "BladeInsight" cloud reporting platform makes actionable reports available to our customers as part of this solution. Pro-Drone Zenith provides for a 50% direct cost saving, and decreases turbine inspection downtime by 6X, as compared to existing methods.

There are two types of wind turbines, a Horizontal Axis Wind Turbine (HAWT) and a Vertical Axis Wind Turbine (VAWT). A HAWT has high efficiencies, but also high costs of materials, transportation, installation and maintenance. A VAWT has low efficiency, but lower costs of materials, transportation, installation and maintenance. In comparison, a VAWT also offers a subtler design with reduced shadow flicker, bird strike, and noise. However, due to the low efficiency of a VAWT, it is not an economically commercial method of producing renewable energy. AB Power has developed a technology to increase the efficiency of a VAWT close to that of a HAWT without sacrificing the cost savings. This has led to a far cheaper method of harnessing energy from the wind than ever before. Due to the affordability of the VAWT, it will have a dramatic impact on the fight against climate change. The technology being developed at AB Power will make renewable energy available to more customers than ever before. Through the growth of AB Power, there will be a direct relationship with the reduction of UK emissions.

The world’s energy market, with an annual turnover of more than € 10 trillion, is in transition. Today’s renewables can replace 20-40% of fossil sources, however, their volatile energy output cause problems with grid stability and matching supply and demand. As a result, additional expenditure in the order of billions of € are required to expand the grid and adding storage solutions. EnerKíte offers a solution – tapping into an as of yet unused and stable energy source, providing twice the yield at half the cost to traditional horizontal axis wind turbines (HAWT). EnerKítes - a future product portfolio of Airborne Wind Energy (AWE) Systems will harness the powerful and steady winds high above the blade tips of today’s wind turbines. Proprietary control software and machine design will make EnerKítes autonomous and robust and matching renewable energy demands even during lull and at night. EnerKíte is a Berlin-based venture led by pioneers in the wind and kite industry. It has developed a 30 kW working prototype that has provided the longest autonomous operation (72 hrs+) of any AWE player in the world. The SME Phase 2 project focuses on optimizing and validating the EK200, a 100 kW unit, as the commercial market entry model. Working closely with the utility company ENGIE, we will ensure that the technology is matured while anchoring the commercialization journey. Our entry strategy is to provide green energy directly where there is demand. We will address the renewable mini-grid market with a volume of €bn 7.2 p.a. - sufficient for a proper business case itself. We will deploy rural wind-storage charging stations to boost the €bn 40 by 2025 eMobility market, growing with a CAGR of 47.9%. EnerKíte’s value chain is centred around certifiable designs, IP and know-how. The need for scalable manufacturing skillsets prompts dialogues with Voith (DE), Siemens (DE) and Vestas (DK). The innovation effort provides a €m 50.9 business opportunity already for 2021-2026.

Awaiting Public Project Summary

Soil is a fundamental resource yet every year some 10 million ha of cropland are lost to soil erosion, mostly due to unsustainable agricultural and forestry practices. Erosion impacts overall sustainability in two ways: (a) reduction in farmland for food production, and (b) discharge of sediments and associated contaminants into water courses polluting water supply, fisheries and aquaculture, and reducing hydropower capacity due to reservoir siltation. Soil erosion and its environmental impacts sit centrally within the Energy-Food-Water-Environment Nexus. New approaches to land management change are required to reduce socio-economic impacts of soil erosion but in spite of its significance, soil erosion is insufficiently understood in its social dimensions, and is almost non-governed in Latin American DAC countries. Two factors may explain this: (a) erosion is often slow and "invisible", or accepted as the norm, and (b) erosion is highly complex, emerging from interaction of socio-economic and natural processes, with interconnected feedbacks between external and internal drivers. Working in collaboration with researchers from Argentina, Brazil, and Mexico, the Chile-UK partnership aims to develop a new integrated approach for understanding and governing soil erosion at the river basin scale. Our multidisciplinary team combines innovative scientific measuring methods and advanced Latin American approaches for socio-cultural intervention to provide a new framework within which soil erosion challenges in Latin America can be addressed.

The transformation of Europe’s energy system creates both challenges and opportunities for the hydropower sector. Hydropower needs to seek out value within the electricity market aligned with other sources of renewable and sustainable energy, whilst operating and building plants in environmentally sensitive and acceptable ways. The call H2020 LC-SC3-CC-4-2018: “Support to sectorial fora”, item 2: “bringing together stakeholders of the hydropower sector in a forum” provides a unique opportunity to bring together the hydropower community and to develop a Research and Innovation Agenda, and a Technology Roadmap mapping implementation of that agenda. These will support implementation of research and innovation for new hydropower technologies and innovative mitigation measures. The HYDROPOWER-EUROPE project delivers these objectives through an extensive programme of stakeholder consultation. The consortium brings together six different associations and networks spanning the whole research and industry value chain. These networks, along with representatives of civil society and European and national authorities, will form the initial stakeholder consultation base. Through an extensive, cyclic programme of consultation – both online and through various regional, European and International workshops – research needs and priorities will be established supporting development of the Hydropower Research and Innovation Agenda. The consultation process also facilitates discussion around issues and perceptions affecting the implementation of hydropower in Europe. Conclusions from this will underpin development of the Technology Roadmap, addressing any issues affecting uptake of the research and innovation agenda. Finally, the HYDROPOWER-EUROPE project will also consider ways in which the forum, established through this initiative, may become sustainable beyond the 3-year project programme, so supporting uptake and implementation of the research and innovation agenda.

Maintenance costs are one of the largest problems in the wind energy market, adding to up to 40% of total wind turbine costs. Blades take the lion’s share of this, with 20-30% of all maintenance costs. Our solution, eolACC is the first condition-based monitoring on-blade sensor system to combine 3 features: blade crack detection, pitch angle measurements and blade icing detection. Monitoring all these features will save wind turbine owners up to €2.9 M across the turbine lifetime, recovering the investment in eolACC in the first 2 months. We studied the target market and competitors. Forecasts predict the wind power O&M market will grow to €22 bn by 2025. eolACC has full Freedom to Operate in our target markets of Europe, North America and Asia. We currently have over 50 customers which have purchased over 200 of our ice detection sensor system, many of which have been asking for an all-in-one solution as eolACC. We will leverage our connection with them to first expand into France, Belgium and the DACH region in 2021, then the rest of Europe and North America in 2022 and Asia in 2023. Our strategy will be to sell our product first to turbine owners directly, and then through large OEMs. We already have registered interest from several of our current customers (Enercon, e.on. Tecnocentre eolien, EVN, Verbund) to implement eolACC into their systems. We will use our current clients, our connection with Phoenix Contact and local sales partners to assist our dissemination efforts. We require a 24-month project with a budget of €1.62 M to bring eolACC to market. Our Work Plan is composed of 3 Technical Work Packages, one Commercial and one for Project Management. Our Phase 2 project will also result in the creation of 6 new jobs. The project is highly profitable, bringing a 4.01 ROI up to 2024 for the €1.62M required to bring our innovation to market. This will translate into a payback period of 2 years and total revenues of almost €12M per year to 2024.

Although renewable energy has always been a priority in UK, the incentives cuts for solar have slowed down new investments. There is a need for more efficient technologies to make the PV market more self-sustainable and preserve the thousands related jobs. Bifacial solar panels (BFPV) is one such technology: light can enter from both sides, thus generating more electricity. Unfortunately, there are issues limiting the wide adoption of the new, more efficient technology, the main one being the uncertainty in the forecast of energy output of BFPV. High uncertainty increases the risk for investors, limiting the proliferation of BFPV. The project builds on the cooperation between RINA and the National Physics Laboratory (NPL) developed during our A4I Round 3 Feasibility Study and aims to develop an innovative method to perform yield studies, with reduced uncertainty on the output of BFPV systems. The project focuses on a key problem in assessing the energy output of BFPV plant: the accurate evaluation of bifacial gain. In our Round 3 work, NPL introduced "effective" albedo (light reflected from the ground) as an input to RINA's energy output assessment method, which incorporates the varying light spectrum of the reflected light as well as the spectral response of solar panels into the analysis. The impact of this method on significantly reducing uncertainty on BFPV energy output estimations was demonstrated, and the energy estimates themselves rose for example sites. They key objectives of the current Round 5 project are: Develop the Round 3 methodologies to be applicable globally; Specify the hardware and procedural requirements for on-site albedo monitoring including uncertainty analysis. Incorporate uncertainties due to additional PV module factors into the bifacial gain estimation. Develop typical effective albedo datasets as a guide when site-specific data are unavailable. Feed into the working group for the improvement of the IEC 616724-1 standard. Determine the impact on financial risk by using different measurement and data analysis methods within BFPV energy forecasts. Benefits from the project will affect the whole value chain of energy, from generation to consumption. More reliable and better-understood measurements and data validation reduce the technical and financial risks of investors, consequently boosting BFPV investments. As a result, more power generated and higher efficiency guaranteed by the BFPV technology will favour a decrease in electricity price for consumers. This will also contribute towards reducing CO2 emissions and the UK's environmental impact.

The latest report of Intergovernmental Panel on Climate Change (IPCC) 'Global warming of 1.5C' emphasises the need for 'rapid and far-reaching' actions now to curb carbon emission to limit global warming and climate change impact. Decarbonising heating is one of the actions which is going to play a key role in reducing carbon emission. The Committee on Climate Change states that insufficient progress has been made towards the low carbon heating homes target that requires immediate attention to meet our carbon budget. It is well known fact that the ground is warmer compared to air in winter and cooler in summer. Therefore our ancestors build caves and homes underground to protect them against extreme cold/hot weather. Geothermal energy pile (GEEP) basically consists of a pile foundation, heat exchanging loops and a heat pump. Heat exchanging loops are usually made of high density polyethylene pipes and carry heat exchanging fluid (water and/or ethylene glycol). Loops are attached to a reinforcement cage and installed into the concrete pile foundations of a building to extract the shallow ground energy via a heat pump to heat the building during winter. The cycle is reversed during summer when heat is collected from the building and stored in the ground. GEEP can play an important role in decarbonising heating as it utilises the sustainable ground energy available under our feet. High initial cost remains the main challenge in deploying heat pump technology. In the case of GEEP, the initial cost can be reduced, if the heat capacity of the concrete is improved and loop length can thus be decreased. This can be achieved by incorporating phase change material (PCM) in the concrete. PCM has a peculiar characteristic that it absorbs or releases large amount of energy during phase change (solid to liquid or liquid to solid). This project aims to develop an innovative solution by combining two technologies GEEP and PCM to obtain more heat energy per unit loop length which would reduce the cost of GEEP significantly. PCM has never been used with GEEP in the past, therefore obvious research questions that come to the mind are (1) how to inject PCM in concrete (2) what would be the effect of PCM on concrete strength and workability (3) how PCM would affect load capacity of GEEP as primary objective of the GEEP is to support structure (4) how much heat energy would be available (5) what would happen to the ground temperature surrounding GEEP (6) how much it would cost (7) whether it would reduce carbon footprint of concrete. We aim to answer all the above research questions by employing sustainable and environmental friendly PCM and impregnate it in light weight aggregates (LWAs) made with waste material (e.g. fly ash, slag, glass). There are three advantages of using LWAs made from waste: first LWAs will replace natural aggregate in concrete as natural aggregates are carbon intense, second LWAs are porous and light so they can absorb large amount of PCM and reduce the weight of concrete, third reuse the waste. Laboratory scale concrete GEEP will be made with PCM impregnated LWAs and tested under heating and cooling load to investigate thermal (heat transfer) and mechanical (load capacity) performance. Extensive experimental and numerical study will be carried out to design and develop novel PCM incorporated GEEP which can provide renewable ground energy for heating and cooling.

Solar Energy is the most abundant renewable energy source available for our Planet. Light energy conversion into chemical energy by photosynthetic organisms is indeed the main conversion energy step, which originated high energy containing fossil deposits, now being depleted. By the way, plant or algae biomass may still be used to produce biofuels, as bio-ethanol, bio-diesel and bio-hydrogen. Microalgae exploitation for biofuels production have the considerable advantages of being sustainable and not in competition with food production, since not-arable lands, waste water and industrial gasses can be used for algae cultivation. Considering that only 45% of the sunlight covers the range of wavelengths that can be absorbed and used for photosynthesis, the maximum photosynthetic efficiency achievable in microalgae is 10%. On these bases, a photobioreactor carrying 600 l/m-2 would produce 294 Tons/ha/year of biomass of which 30% to 80%, depending on strain and growth conditions, being oil. However this potential has not been exploited yet, since biomass and biofuels yield on industrial scale obtained up to now were relatively low and with high costs of production. The main limitation encountered for sustained biomass production in microalgae by sunlight conversion is low light use efficiency, reduced from the theoretical value of 10% to 1-3%. This low light use efficiency is mainly due to a combined effect of reduced light penetration to deeper layers in highly pigmented cultures, where light available is almost completely absorbed by the outer layers, and an extremely high (up to 80%) thermal dissipation of the light absorbed. This project aims to investigate the molecular basis for efficient light energy conversion into chemical energy, in order to significantly increase the biomass production in microalgae combining a solid investigation of the principles of light energy conversion with biotechnological engineering of algal strains.
