Advice Notes on Solar Thermal Technology Economics for the NPA Region

Solar Thermal

The Advice Notes aim to provide introductory material for entrepreneurs, startups and SME’s, considering to enter into the renewable energy sphere and based in the NPA regions partners to GREBE. The scope of the Advice Note covers regional, trade and industry, renewable energy (RE), technology information from Ireland, Northern Ireland, Scotland, Iceland and Finland. Different partner regions have different level of deployment of the various RE technologies covered by the Advice Notes. Thus, the level of information will vary depending on the level of deployment for each technology. For example, wind is not deployed on a large scale in North Karelia (Finland); however, it is widely deployed in Scotland, Ireland and Northern Ireland.

Full details are available on the GREBE website:

Solar thermal systems use solar collectors to absorb energy from the sun and transfer it, using heat exchangers, to heat water. Solar thermal delivers hot water at temperatures of between 55ºC and 65ºC. This is a comparatively mature technology and many installations date back to the 1970s. There are two main types of solar heating collectors:

  • Flat-plate collectors – a sheet of black metal, that absorbs the sun’s energy, encases the collector system. Water is fed through the system in pipes, which conduct the heat to the water.
  • Evacuated tubes – a series of parallel glass heat tubes grouped together. Each tube contains an absorber tube enclosed within a vacuum. Sunlight passing through the outer glass tube heats the absorber tube contained within it, and in doing so, the heat is transferred to a liquid flowing through the tubes.

Evacuated tubes are the most efficient type of solar water collector at around 80% efficiency (compared to around 70% for flat plate collectors). Correspondingly, they also cost more to manufacture; thus, they are more expensive. Modern solar thermal technologies are dependable, efficient and completely safe. Solar thermal technology can have up to 80% efficiency rate in delivering heat to your business.

New scheme encouraging homeowners to install solar panels launched today

solarPanelsRoofInstall_large

A new scheme encouraging homeowners to install solar panels has been launched this morning. The pilot scheme offers grants for the installation of solar panels and extra funds to install battery storage systems.  Environment Minister Denis Naughten says the scheme will allow people to turn their home into their very own “renewable power station.” He said homeowners can save around €220 in electricity costs every year by taking advantage of the scheme.

Announcing the grants for homeowners, Minister for Communications, Climate Action and Environment, Denis Naughten TD said: “Turning your home into a renewable power station is now one step closer. Microgeneration is an incredibly exciting space that will allow citizens in local communities to generate their own electricity and contribute towards Ireland’s climate action targets. With this grant that I am announcing today, a typical 3-bed semi-detached house would spend about €1,800 on a solar panel system and would save approximately €220 per year on their electricity bills.”

The Minister added: “The pilot scheme will be subject to a 6-month review at which time the costs of installation will be assessed and further opportunities to broaden this scheme to other groups and other technologies will be explored.” The scheme will be funded by the Department of Communications, Climate Action and Environment and administered by the Sustainable Energy Authority of Ireland (SEAI). The grant is available for homes built and occupied before 2011 and details of eligibility criteria and how to apply are set out here. A registered solar PV installer must be used and a full list of registered installers is also available on the SEAI website.

Government approves scheme to diversify green energy

DNaughten

A new scheme designed to diversify the State’s renewable energy production and boost its chances of meeting key EU targets has been approved by the Government. The Renewable Electricity Support Scheme (RESS) is designed to help the State meet its renewable pledges up to 2030. Its first priority is to boost renewable energy production quickly to help turn 16 per cent of the State’s energy needs “green” by 2020. The scheme will incentivise the introduction of sufficient renewable electricity generation by promoting investment by community groups in green projects. Offshore wind and tidal projects will be central if the State is to meet its targets, while it is expected to also support an immediate scale-up of solar projects. Projects looking for support under the scheme will need to meet pre-qualification criteria, including offering the community an opportunity to invest in and take ownership of a portion of renewable projects in their local area.

Auction system

The RESS scheme introduces a new auction system where types of energy will bid for State support. It is proposed that the scheme be funded through the Public Service Obligation Levy, which is a charge on consumers to support the generation of electricity from renewable sources. Individual projects will not be capped, but the Government will limit the amount that a single technology, such as wind or tidal, can win in a single auction. The auctions will be held at frequent intervals throughout the lifetime of the scheme to allow the State to take advantage of falling technology costs. The first auction in 2019 will prioritise “shovel-ready projects”. “By not auctioning all the required capacity at once, we will not be locking in higher costs for consumers for the entirety of the scheme,” Minister for the Environment Denis Naughten said. In effect it should make it easier for solar and offshore wind to get investment, yielding multiple billions for green projects over the next 15 years.

2020 vision

It is hoped renewable energy will represent 40 per cent of the State’s gross electricity consumption by 2020, and 55 per cent by 2030, subject to determining the cost-effective level that will be set out in the draft National Energy and Climate Plan, which must be approved by the EU and in place by the end of 2019. In addition the scheme is intended to deliver broader energy policy objectives, including enhancing security of supply. “This scheme will mark a shift from guaranteed fixed prices for renewable generators to a more market-oriented mechanism [auctions] where the cost of support will be determined by competitive bidding between renewable generators,” said Mr Naughten. The next step for the Government is to secure EU approval for the package, which typically takes six to nine months. It is estimated that the first auction will be in the second half of next year.

Power from Biomass project final seminar, Monday 11th June, Joensuu

KUAS

The Rural development programme co-financed Power from Biomass project completed its work in June 2018 after three years of renewable energy development in North Karelia, Finland. The project cooperating closely with GREBE in North Karelia, resulted in several new investments including two solar PV and energy storage systems in community buildings of Höljäkkä and Haikola in Nurmes. Project also established a regional network of 15 renewable energy demonstration sites.

The final seminar held in Joensuu, presented projects main outputs, latest developments in renewable electricity production, biomass-based small-scale combined heat and power, solar energy project of heat enterprises, and intelligent solar PV systems.

Project manager Antti Niemi from Pielinen Karelia Development Company PIKES Ltd. summarized the project results. The project established a regional demonstration network with 15 sites demonstrating renewable energy production systems. The Energiaraitti website presents the technical and economic information and live-information of solar PV systems. New production units established were mostly solar PV and some energy storages systems in farms, other rural enterprises and community buildings. The biomass-based renewable energy had a challenging business environment due to low price of fossil fuel oil. Despite, also some new biomass-based energy systems were established.

Project manager Kim Blomqvist from Karelia UAS presented the solar PV systems integrated into biomass-based district heating plants. Investments were made for 7 district heating plants with total annual production of 52 MWh. The heating plans were considered suitable for the solar PV as they have balanced electricity demand.

Marketing and product development manager Kimmo Tolvanen, representing regional energy company PKS, presented an in-depth overview of the energy system development in Finland and North Karelia. The main game changers in the energy system are expected to consist of wind and solar power production, energy storages and digitalization working all effectively together. The energy grid changes toward decentralised, intelligent and adaptive systems are evident. In addition, electricity markets are in transition, and new service developments are expected throughout the system from production to consumption.

Project coordinator Anssi Kokkonen from Karelia UAS presented the technical solutions of biomass-based combined heat and power production. The solutions included woodchip gasification plant (Volter Ltd.), Nano-chp Stirling engine (9 kWth + 0.6 kWe), fuelled by wood pellets (Ökofen).  Both solutions are demonstrated at Sirkkala Energy Park by Karelia UAS.

Project manager Toni Hannula from energy company ESE (Etelä-Savon Energia, Mikkeli) presented intelligent solar power systems. The smart energy transition project by Lappeenranta Technological University has generated an overview of the systems change. The ESE has been successful in establishing biogas fuel stations, and piloting intelligent solar PV systems with 48 hours production forecast and directing the production optimally depending on energy price (electricity spot-price optimizing) and production and consumption loads. The system is piloted in Lumme Energia Oy estates.

The Power from Biomass project developed as a diverse renewable energy project and delivered several new services and RE production sites were established. The project had an international element through cooperation and networks of the GREBE project.

Hybrid solutions case information from Finland now available!

Farm

A Case video has been published by GREBE partner LUKE on Itikka farm Iisalmi, Finland. The Itikka farm is located in a rural forest and agriculture dominated region very near to the city of Iisalmi in the region of Northern Savo, Finland. Currently energy production plays an important role in the farm´s business. The energy production on the farm includes an own biodiesel production unit, a wind turbine, solar panels and a ground source heat pump.

The Itikka farm is in a private family ownership since the year 1905. The farm has a high annual energy consumption of approximately 150 000 kWh especially high needs for seed processing and drying. The Itikka farm currently employs three external employees with one being employed in the field of energy.

The system is driven by the objective of being self-sufficient by meeting the energy demand of the farm with local resource and moving away from fossil energy. Currently a self-sufficiency of about 50-70% is achieved. Own energy consumption (electricity, heat and fuels) of about 150 MWh, drives own production. The farm has available by-products that can be utilised in bio-oil and briquette production.

The Natural Resources Institute Finland (Luke) has now published a GREBE video on the Itikka farm hybrid solutions case. The video is available in two language versions, English and Finnish.
