Resource Assessment Toolkit for Wind Energy

Wind

The Toolkit outlines best practice techniques for assessing wind resource potentials as a foundation for a wind resource assessment. The wind resource assessment entails industry-accepted guidelines for planning and conducting a wind resource measurement program to support a wind energy feasibility initiative. These guidelines do not embody every single potential technique of conducting a quality wind measurement program, but they address the most essential elements based on field-proven experience.

The scope of the Toolkit covers:

  • Wind resource assessment 101
  • Sitting of monitoring systems
  • Measurement parameters and monitoring instruments
  • Installation of monitoring stations
  • Site operation and maintenance
  • Data collection and management
  • Data validation
  • Data processing
  • Comparison of observed wind data with historical norm
  • Wind flow modelling

The first wind turbines for electricity generation were developed at the beginning of the 20th century. Thus, wind technology is one of the most mature and proven technologies on the market. In 2015, the wind energy industry installed 12.8 GW in the EU – more than gas and coal combined. Globally, the current wind power installation capacity has reached 435GW with a significant growth rate of 16.4% in 2014 and 17.2% in 2015.

Wind turbines offer the prospects of cost efficient generation of electricity and fast return on investment. The economic feasibility of wind turbines depends primarily on the wind speed. Usually, the greater the long term annual average wind speed, the more electricity will be generated and the faster the investment will pay back. However, it is important to access the wind power potential (WPP) at any prospective location to decide the capacity of wind resource for electricity generation within available time limits of wind duration. Hence, it is relevant to observe the wind characteristics and type of wind turbine technology suitable for any given promising location. These factors are very much helpful for wind power developers and investors to make a decision with respect to the economic constraints.

The Influence of Environmental Conditions in NPA and Arctic Regions

4.3 pic

The key requirement of this work package is the development of a database (and supporting summary report), compiling information for potential renewable energy business and technology solutions to help overcome environmental and climatic challenges in the NPA programme region. Technology solutions cover installation, operation and maintenance of equipment, not the design and manufacture of components.

The objective of the database is to identify the main environmental and climatic challenges, and outline technological and business solutions to these challenges, creating a database of these for 8 different categories of renewable energy technology. It is designed for use by new and existing renewable energy businesses, to inform them of the challenges they may face in developing their business and how these will be overcome.

A range of examples (where available) have been highlighted on how the challenges identified have been overcome. Specific regional related innovations and smart solutions from local business on technology driven RE-solutions have been documented, with the intention of passing on this knowledge to other regions in the NPA not involved in the GREBE Project.

The 8 renewable energy technology categories identified by the GREBE Project partnership are:

  1. Biomass
  2. Wind (Onshore only)
  3. Solar PV
  4. Solar Thermal
  5. Hydro
  6. Ground source heat pump
  7. Air source heat pump
  8. Anaerobic Digestion (farm scale/agricultural)

The database is located on the Renewable Business Platform and can be downloaded here.

Resource Assessment Toolkit for Solar Energy

SolarThe Toolkit outlines best practice techniques for assessing solar resource potentials as a foundation for a solar resource assessment. Solar resource assessment is indispensable in estimating the solar potential in a given location, the social and environmental impacts accompanying the resources exploitation and the economic viability of solar utilization scenarios.

The scope of the Toolkit covers:

  • Governing principles of solar energy
  • Measuring Solar Irradiation
  • Parameters for choice of optimal measurement station
  • Data acquisition and quality control
  • Solar radiation modelling – satellite-based models
  • Applying solar resource data to solar energy projects
  • Forecasting Solar Irradiation
  • Best practices in on-site monitoring programmes

Map

Solar energy is obtainable in abundance in most parts of the world, even in the NPA remit. As seen in the solar irradiation map above, the NPA Region’s average sum of solar irradiation is well below most parts of Europe. However, during the summer period, the countries based in the NPA region get around 17 to 19 hours of daylight and those in the Arctic Circle get 24 hours. Solar PV requires daylight (solar irradiation), rather than sunshine and high temperatures, which makes it a viable technology choice for businesses in the NPA region.

Resource Assessment Toolkit for Biomass Energy

Biomass

The Toolkit outlines best practice techniques for assessing biomass resource potentials as a foundation for a biomass resource assessment. Biomass resource assessment is indispensable in estimating the bioenergy potential in a given location, the social and environmental impacts accompanying the resources production and the economic viability of biomass utilization scenarios.

The scope of the Toolkit covers:

  • Resource potential – theoretical, technical, economic or implementation potential
  • Approaches for estimation of resource potential – (resource focused, demand driven or integrated approach)
  • General principles, techniques and methods when undertaking a biomass resource assessment
  • Forest biomass and methods for resource assessment
  • Energy crops and methods for resource assessment
  • Agricultural residues and methods for resource assessment
  • Organic waste and methods for resource assessment
  • Global and country specific tools to make preliminary resource assessment and how to use them

Lumber stacks

The classification in types of biomass potentials is the first and most important step when undertaking a biomass resource assessment as it provides insight into explicit conditions, assumptions and limitation made in the assessment. The potential of the resource will define the feasibility of the project, return on investments, environmental considerations, coupled with social and political frameworks.

Advice Notes on Ground & Air Source Heat Pumps Technology Economics for the NPA Region

GSHP

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:

http://grebeproject.eu/wp-content/uploads/2017/10/GREBE-Advice-Notes-GSHP-ASHP.pdf

The focus of the Advice Notes is on regional information of some of the main economic characteristics sited as imperative, when making an informed choice, regarding which RE technology may be the optimal choice for a new business venture:

  • Costs and economics associated with the relevant technology
  • Support schemes available, relevant to the technology
  • Government allowance/exemptions, relevant to the technology
  • Funding available for capital costs of the relevant technology
  • List of the relevant to the technology suppliers/developers, with focus on local/regional, suppliers/developers and the products and services they offer.

Heat pumps offer a means to access and utilize the thermal energy that is contained naturally in air, water or the ground. Heat pumps extract low-grade energy from the surrounding environment (air, water, and ground) and transform it into usable energy at a higher temperature suitable for space and water heating. Any kind of heat pump will need to be powered by electricity. Thus, the coefficient of performance (COP), which is the amount of electricity input, is a very important factor when considering GSHP or ASHP. For example if it takes 1 unit of electricity input to produce 4 units of heat output, the CoP will be 4. One of the crucial factors for the CoP is the temperature required by the heating system as CoP is higher when the required temperature is lower (35- 45°C).

Therefore, heat pumps are appropriate for buildings that have these lower temperature heating systems. As these can be costly to retrofit, new buildings which are already fitted with low temperature heating are apt for heat pump technology. For a GSHP or ASHP system a minimum of CoP 3 is needed in order to be a viable option offering savings both in costs and C02 emissions.

The Advice Notes will cover Ground Source Heat Pump (GSHP) and Air Source Heat Pump (ASHP).

GSHP systems make use of the temperature difference between above-ground (air) temperatures and below-ground temperatures for heating or cooling. GSHPs take low-level heat from solar energy stored in the earth and convert it to high-grade heat by using an electrically driven or gas-powered heat pump containing a heat exchanger. A fluid, mixture of water and antifreeze, is circulated in a closed loop system, which picks up heat from the ground and then passes through the heat exchanger in the heat pump, which extracts the heat from the fluid. Heat pumps deliver heat most efficiently at about 30°C which is usually used to deliver space heating to buildings. GSHPs cover a wide range of capacities, from a few kW to hundreds of kW.

Air-source heat pumps (ASHPs) work on the same principle as GSHP, by taking low-grade thermal energy from the air (using an air-source collector outside of the building) and converting it to useful heat by means of the vapour compression cycle. ASHPs are in common use in commercial-scale heating, ventilation and AC systems as they can meet both heating and cooling demand. Installation of an ASHP includes fixing an external unit and drilling holes through the building wall with and an extra pipework may be required. The main steps for deciding if an ASHP is an apt choice are the same as those for a GSHP system, without the need for a ground survey.
