#COP21shipping – Tackling global climate change is a concern of all European ports, writes the European Sea Ports Organisation (ESPO).

European ports overall consider that the 2015 Paris Climate Conference is a historic milestone for enhancing global collective action and moving towards a low-carbon and climate-resilient society. That is why the ESPO decided to join the “Think Climate” coalition that has been set up under the umbrella of PIANC, the World Association for Waterborne Transport Infrastructure.

Think Climate brings together major international associations with interests in waterborne transport infrastructure, with the objective to help the sector respond to climate change. By further understanding, providing targeted technical support and building capacity, the coalition has a double aim: first of all, to promote the reduction of greenhouse gas emissions, by shifting to low carbon maritime and inland waterway transport infrastructure, secondly, address ways to adapt maritime and waterborne infrastructure and operations to the potential impacts of climate change such as sea level rise and extreme weather conditions. On 6 December, PIANC’s Think Climate coalition formally launched its 2015-2020 “Navigating a Changing Climate” Action Plan.

“We are very pleased we can actively support the Think Climate initiative and step up efforts to both mitigate and adapt to climate change. The engagement of European ports towards addressing climate change is not new. Since years already, there is, among ESPO members, a strong coalition of the willing to pro-actively work on energy reduction and climate change. European ports are key nodes in the global transport and supply chain and play an important role in the supply of energy. Around 40% of the commodities of European ports are sources of energy. With international trade volumes expected to further increase, we should develop ways to do more with less emissions. Moreover, we should reflect on how to play an active role in the transition to alternative and renewable energy”, said ESPO Secretary General Isabelle Ryckbost.

The engagement of European port in Climate Change is not new

Even if port infrastructure and operations typically account for only a small proportion of the greenhouse gas emissions to bring goods from origin to destination, European ports are committed to give the good example in minimising the emissions associated with their infrastructure and activities and to strive towards carbon neutrality. The ESPO Green Guide of 2012 has a section dedicated to energy consumption and climate change that calls for concrete action and highlights the best practice examples of European ports.

Port authorities can further bear an influence in reducing the carbon footprint of port areas and the logistic chain.

Engaging with their tenants and operators, port authorities increasingly develop and implement monitoring tools, such as carbon footprint and reporting for the port area and beyond. More and more ports also implement environmentally differentiated port charges to encourage and reward greener behaviour. More than 25 European ports nowadays provide incentives to greener vessels on the basis of the Environmental Ship Index (ESI) tool. ESI has been developed by the World Ports Climate Initiative (WPCI) under the umbrella of the International Association of Ports and Harbours (IAPH) and recently celebrated its 5th year anniversary. ESPO fully supports since the beginning all the tools of WPCI and encourages its member ports to get involved.

Further to the existing port initiatives, European Ports call for:

1. Further steps towards increasing efficiency: do more with less emissions

In order to match the needed reduction of the emissions with the expected growth in freight traffic volumes, maritime transport has to become more efficient and the existing capacity has to be used in a more optimal way. To address this challenge, the internal market for maritime transport should be materialised. Shorter turnaround times will positively affect emissions.

The European transport and port sector should seriously look into the untapped potential of further digitalisation. According to the World Economic forum, only about 40% of load capacity is effectively being used today. A further digitalisation must lead to a better utilisation of the existing capacity and infrastructure in ports, to more efficient planning regimes in the whole logistic chain and to a higher overall efficiency of the European Transport System. European ports can play a pivotal role in this process.

2. Ports to play an active role in changing the energy landscape

Ports play an important role in the supply, import, export and even sometimes the production of both conventional and alternative energy. As such, ports can actively manage and promote the transition to alternative and renewable energies.

The Clean Fuel Strategy adopted in 2013 obliges European core ports to provide for LNG refuelling points and to foresee shore side electricity where possible. ESPO encourages ports to meet these obligations as soon as possible.

In addition, ports are an ideal place for exploiting the potential of circular economy and find ways for eliminating waste or using by-products in an efficient way, and thus reducing carbon emissions. The port authority can be the perfect match maker in bringing together the different stakeholders in the port and can help paving the way for a circular economy in the port.

3. Paris to give a clear mandate to IMO to strengthen its work on reducing shipping emissions

Even if international shipping produces about 2.2% of world’s total CO2 emissions, whereas it transports about 90% of world trade, shipping should clearly contribute to the greenhouse gas emissions reductions like any other sector.

Shipping is a global industry. The Paris conference must therefore be seen as a milestone to further enhance the work at IMO level towards this direction. ESPO acknowledges that the recently adopted tools such as the Energy Efficiency Design Index (EEDI) and the Ship Energy Efficiency Management Plan (SEEMP), are steps in the right direction and need to be given a fair chance. It is clear however that more needs to be done at the international level on monitoring, reporting and verification of emissions, on setting concrete reduction targets at global level and on developing further instruments to achieve those.

Ireland's Offshore Renewable Energy

Because of Ireland's location at the Atlantic edge of the EU, it has more offshore energy potential than most other countries in Europe. The conditions are suitable for the development of the full range of current offshore renewable energy technologies.

Offshore Renewable Energy FAQs

Offshore renewable energy draws on the natural energy provided by wind, wave and tide to convert it into electricity for industry and domestic consumption.

Offshore wind is the most advanced technology, using fixed wind turbines in coastal areas, while floating wind is a developing technology more suited to deeper water. In 2018, offshore wind provided a tiny fraction of global electricity supply, but it is set to expand strongly in the coming decades into a USD 1 trillion business, according to the International Energy Agency (IEA). It says that turbines are growing in size and in power capacity, which in turn is "delivering major performance and cost improvements for offshore wind farms".

The global offshore wind market grew nearly 30% per year between 2010 and 2018, according to the IEA, due to rapid technology improvements, It calculated that about 150 new offshore wind projects are in active development around the world. Europe in particular has fostered the technology's development, led by Britain, Germany and Denmark, but China added more capacity than any other country in 2018.

A report for the Irish Wind Energy Assocation (IWEA) by the Carbon Trust – a British government-backed limited company established to accelerate Britain's move to a low carbon economy - says there are currently 14 fixed-bottom wind energy projects, four floating wind projects and one project that has yet to choose a technology at some stage of development in Irish waters. Some of these projects are aiming to build before 2030 to contribute to the 5GW target set by the Irish government, and others are expected to build after 2030. These projects have to secure planning permission, obtain a grid connection and also be successful in a competitive auction in the Renewable Electricity Support Scheme (RESS).

The electricity generated by each turbine is collected by an offshore electricity substation located within the wind farm. Seabed cables connect the offshore substation to an onshore substation on the coast. These cables transport the electricity to land from where it will be used to power homes, farms and businesses around Ireland. The offshore developer works with EirGrid, which operates the national grid, to identify how best to do this and where exactly on the grid the project should connect.

The new Marine Planning and Development Management Bill will create a new streamlined system for planning permission for activity or infrastructure in Irish waters or on the seabed, including offshore wind farms. It is due to be published before the end of 2020 and enacted in 2021.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE. Is there scope for community involvement in offshore wind? The IWEA says that from the early stages of a project, the wind farm developer "should be engaging with the local community to inform them about the project, answer their questions and listen to their concerns". It says this provides the community with "the opportunity to work with the developer to help shape the final layout and design of the project". Listening to fishing industry concerns, and how fishermen may be affected by survey works, construction and eventual operation of a project is "of particular concern to developers", the IWEA says. It says there will also be a community benefit fund put in place for each project. It says the final details of this will be addressed in the design of the RESS (see below) for offshore wind but it has the potential to be "tens of millions of euro over the 15 years of the RESS contract". The Government is also considering the possibility that communities will be enabled to invest in offshore wind farms though there is "no clarity yet on how this would work", the IWEA says.

Based on current plans, it would amount to around 12 GW of offshore wind energy. However, the IWEA points out that is unlikely that all of the projects planned will be completed. The industry says there is even more significant potential for floating offshore wind off Ireland's west coast and the Programme for Government contains a commitment to develop a long-term plan for at least 30 GW of floating offshore wind in our deeper waters.

There are many different models of turbines. The larger a turbine, the more efficient it is in producing electricity at a good price. In choosing a turbine model the developer will be conscious of this ,but also has to be aware the impact of the turbine on the environment, marine life, biodiversity and visual impact. As a broad rule an offshore wind turbine will have a tip-height of between 165m and 215m tall. However, turbine technology is evolving at a rapid rate with larger more efficient turbines anticipated on the market in the coming years.

 

The Renewable Electricity Support Scheme is designed to support the development of renewable energy projects in Ireland. Under the scheme wind farms and solar farms compete against each other in an auction with the projects which offer power at the lowest price awarded contracts. These contracts provide them with a guaranteed price for their power for 15 years. If they obtain a better price for their electricity on the wholesale market they must return the difference to the consumer.

Yes. The first auction for offshore renewable energy projects is expected to take place in late 2021.

Cost is one difference, and technology is another. Floating wind farm technology is relatively new, but allows use of deeper water. Ireland's 50-metre contour line is the limit for traditional bottom-fixed wind farms, and it is also very close to population centres, which makes visibility of large turbines an issue - hence the attraction of floating structures Do offshore wind farms pose a navigational hazard to shipping? Inshore fishermen do have valid concerns. One of the first steps in identifying a site as a potential location for an offshore wind farm is to identify and assess the level of existing marine activity in the area and this particularly includes shipping. The National Marine Planning Framework aims to create, for the first time, a plan to balance the various kinds of offshore activity with the protection of the Irish marine environment. This is expected to be published before the end of 2020, and will set out clearly where is suitable for offshore renewable energy development and where it is not - due, for example, to shipping movements and safe navigation.

YEnvironmental organisations are concerned about the impact of turbines on bird populations, particularly migrating birds. A Danish scientific study published in 2019 found evidence that larger birds were tending to avoid turbine blades, but said it didn't have sufficient evidence for smaller birds – and cautioned that the cumulative effect of farms could still have an impact on bird movements. A full environmental impact assessment has to be carried out before a developer can apply for planning permission to develop an offshore wind farm. This would include desk-based studies as well as extensive surveys of the population and movements of birds and marine mammals, as well as fish and seabed habitats. If a potential environmental impact is identified the developer must, as part of the planning application, show how the project will be designed in such a way as to avoid the impact or to mitigate against it.

A typical 500 MW offshore wind farm would require an operations and maintenance base which would be on the nearby coast. Such a project would generally create between 80-100 fulltime jobs, according to the IWEA. There would also be a substantial increase to in-direct employment and associated socio-economic benefit to the surrounding area where the operation and maintenance hub is located.

The recent Carbon Trust report for the IWEA, entitled Harnessing our potential, identified significant skills shortages for offshore wind in Ireland across the areas of engineering financial services and logistics. The IWEA says that as Ireland is a relatively new entrant to the offshore wind market, there are "opportunities to develop and implement strategies to address the skills shortages for delivering offshore wind and for Ireland to be a net exporter of human capital and skills to the highly competitive global offshore wind supply chain". Offshore wind requires a diverse workforce with jobs in both transferable (for example from the oil and gas sector) and specialist disciplines across apprenticeships and higher education. IWEA have a training network called the Green Tech Skillnet that facilitates training and networking opportunities in the renewable energy sector.

It is expected that developing the 3.5 GW of offshore wind energy identified in the Government's Climate Action Plan would create around 2,500 jobs in construction and development and around 700 permanent operations and maintenance jobs. The Programme for Government published in 2020 has an enhanced target of 5 GW of offshore wind which would create even more employment. The industry says that in the initial stages, the development of offshore wind energy would create employment in conducting environmental surveys, community engagement and development applications for planning. As a site moves to construction, people with backgrounds in various types of engineering, marine construction and marine transport would be recruited. Once the site is up and running , a project requires a team of turbine technicians, engineers and administrators to ensure the wind farm is fully and properly maintained, as well as crew for the crew transfer vessels transporting workers from shore to the turbines.

The IEA says that today's offshore wind market "doesn't even come close to tapping the full potential – with high-quality resources available in most major markets". It estimates that offshore wind has the potential to generate more than 420 000 Terawatt hours per year (TWh/yr) worldwide – as in more than 18 times the current global electricity demand. One Terawatt is 114 megawatts, and to put it in context, Scotland it has a population a little over 5 million and requires 25 TWh/yr of electrical energy.

Not as advanced as wind, with anchoring a big challenge – given that the most effective wave energy has to be in the most energetic locations, such as the Irish west coast. Britain, Ireland and Portugal are regarded as most advanced in developing wave energy technology. The prize is significant, the industry says, as there are forecasts that varying between 4000TWh/yr to 29500TWh/yr. Europe consumes around 3000TWh/year.

The industry has two main umbrella organisations – the Irish Wind Energy Association, which represents both onshore and offshore wind, and the Marine Renewables Industry Association, which focuses on all types of renewable in the marine environment.
