S&P Global Ratings rated its first onshore wind project in 2003. Since then, the renewable energy sector has undergone tremendous expansion. In the past decade alone, its compound annual growth rate has totalled 20%, thanks largely to the rising awareness of how using fossil fuels for power generation contributes to climate change. In Latin America in particular, where most renewable capacity comes from large hydro plants, onshore wind power sources are playing an increasingly important role. Oaxaca, a region in Mexico, for example, is considered one of the best regions worldwide for onshore wind farms. Its geological formation creates a corridor with consistently strong winds. So, the favourable wind resource, in combination with lower operation and maintenance cost, resulted in the upside of the credit outlook in the region. A global outlook Last year alone, onshore wind added approximately 53 gigawatts (GW) to the global capacity grid – bringing the total to around 540 GW. This is partly due to higher capacity factors and falling prices throughout the wind turbine supply chain, both of which are fostering onshore wind power’s rapid development. However, the sector’s growth isn’t without serious challenges. Wind resource availability has often failed to live up to the initial estimations made

The offshore industry is now recognising the potential of utilising hybrid power linked to innovative propulsion systems. However, the cost of adopting hybrid technology on retrofit projects and new vessels requires a viable business case to justify higher capital expenditure (CAPEX). Offshore maritime cannot afford to go ‘green’ for no reason; there simply is not the margin to add on another layer of costs. They need a viable business case or they need a compliance case. Which raises the burning question - how can the offshore sector finance hybrid marine power? Other transport sectors around the world are successfully utilising hybrid systems. Automotive manufacturers including Tesla and BMW are re-defining energy possibilities for land transport. The technology is transitioning from high performance automobiles to city busses and the future of aviation. Technology Readiness Level (TRL) is rated 1 to 9. Component parts of maritime hybrid powertrains typically achieve TRL8. By definition this is, ‘actual system completed and qualified through test and demonstration’. But maritime needs to move up to TRL9, ‘actual system proven through successful mission operations’. Emissions Compliance versus Engineering Efficiency Dramatically reducing pollution in both water and air, particularly in ports and around people to maintain their health, is becoming the most significant driver for change

For a long time we at PES have been saying that components in the wind industry are getting bigger and bigger and obviously this includes the tools of the trade. How much more increase can there be in size and how does this affect the weight? Huisman from the beginning Before looking at the developments in the wind industry, let’s take a closer look at Huisman, one of the manufacturers of offshore wind tools and cranes, and start at the beginning. Huisman, founded in 1929 and was originally a construction company for steel structures and derricks. In 1987 Huisman joined forces with engineering company ITREC to develop steel construction projects entirely under its own management. In 1983, during the early ITREC days, the mast crane concept was developed: a compact and innovative crane design for heavy offshore lifts: the Heavy Lift Mast Crane. Another important development from the early days is Active Heave compensation. Currently, this system is also delivered in an electric version, with frequency controlled motors. Unlike in the second half of the eighties, when everyone considered 300m water depth to be extremely deep, indeed nowadays, we consider this to be shallow water. With innovation being at the heart of the

PES asked Steve Sawyer, Secretary General at GWEC for his outlook on the future of the wind industry markets. Will prices continue to fall or have they reached their lowest point? Where is the market increasing? Where is it slowing down? Read on and find out… The global wind power market remained above 50 GW in 2017, with Europe, India and the offshore sector all having record years. Chinese installations were down - 19.66 GW - but the rest of the world made up for most of that. Total installations in 2017 were 52,492 MW, bringing the global total to 539,123 MW. The annual market was in fact down 3.8% on 2016’s 54,642 MW; and the cumulative total is up 11% over 2016’s year-end total of 487,219 MW. The offshore segment had a record year with 4,331 MW of installations, an 87% increase on the 2016 market, bringing total global installations to 18,814 MW, and representing a 30% increase in cumulative capacity globally. Offshore was about 8.4% of the 2017 annual market, and represents about 3.5% of cumulative installed capacity, but it’s growing quickly. Total new investment in clean energy rose to US$ 333.5bn (€296.8bn1) in 2017, up 3% over 2016, but still

The search for reliability in the renewable energy sector is an ongoing one. Increasing reliability in wind turbine parts reduces downtime and costs while allowing for a constant flow of power to the grid. Also, by finding new ways to improve processes and reduce the time and effort taken to identify and replace faulty parts, companies can drastically improve efficiency. For engineers in the Energy & Motion Technologies division at Galway-based Test Laboratory Anecto, striking a balance between innovation and quality control is essential to increasing reliability. They insist that innovation and research comes in tandem with quality control; citing as examples, their in-house refurbishment processes as well as recent work with the UK’s Durham University that has breathed new light on the stresses that changing wind patterns cause to a power converter’s IGBT and led to their conclusion that a ‘holistic approach to wind turbine power converter reliability’ is more advisable in future. Anecto test laboratory started as an electronics test house in 1994 but developed into a major provider of product and packaging testing for the medical devices and many other sectors. By leveraging the engineering talent they had on site and innovating, the company pushed into the renewable energy

PES asked Tyler Ogden, Lux Research Inc. to give us his expert viewpoint on the longevity of PV systems. Lux Research is a leading provider of research and advisory services, helping clients drive growth through technology innovation. Utility-scale systems are now a competitive choice for electricity supply, with bids undercutting conventional sources of generation in some regions, while other regions see competitive subsidy-free deployments. This has largely been the result of declining module costs. Manufacturers have obtained significant economies of scale and have continued to adopt higher efficiency cell technologies. Meanwhile other players across the supply chain that offer balance of system components and developed projects have reached maturity, contributing to lowering the capital expense of new installations to a point where sub dollar-per-watt systems are now feasible. However, the rate of cost declines has begun to taper off. If solar costs are to continue to drop and maintain the precedent of low-cost renewables, the industry must look elsewhere – must look forward in time. The standard lifetime for a photovoltaic installation is 20 to 25 years, nearly double the time from when the global solar industry began to mature in early 2010s. The focus has primarily been in reducing dollar-per-watt costs to

In this day and age recycling should be a top priority throughout the renewable energies sector. Dr. Palitzsch from Loser Chemie GmbH, reminds PES readers about the latest update to the EU waste legislation. It’s remarkable to see how it is possible to achieve total recovery of all materials, in both thin-film PV and silicon-based modules. According to the latest revision of the EU waste legislation (WEEE), producers of solar photovoltaic panels are responsible for the disposal and recycling of the modules they sell in EU Member States. In addition to this we also have a few other reasons to recycle all and any used materials. Recycling allows the materials, in otherwise one-use products, to go on to become something new and saves resources involved in sourcing new materials: that´s why it is amazing. And the best way is, of course, the complete recovery of all components. In recent years, Loser Chemie GmbH has led the search for a universal concept, for as many solar module types as possible. Today, the company has introduced a technology that enables the recycling of both thin-film PV and silicon-based modules. An important role is played by light and water. Used correctly complete disassembly of old solar
