There has been plenty of talk lately surrounding the US ‘fiscal cliff’. But while a short-tem deal struck between Democrats and Republicans in the US Senate has averted the potential crisis for now, in Europe, the power industry is said to be facing a ‘cliff edge’ of its own in the form of numerous regulatory and financial challenges. And unlike in the US, there are no short-term solutions.

According to ENEL president Fulvio Conti, up to €1trn is required in the run up to 2020 for expansion of renewables capacity, for construction of new plants to back up that renewable generation, and for further development and deployment of innovative technologies such as smart grids and electricity storage. Yet market uncertainty and lack of coherence between national and European policy are blocking access to capital in Europe, such that he recently described the power sector as being ‘uninvestable’.

On average, investment in the power sector is set to grow by 0-2% per annum according to latest available figures from Eurelectric (the Union of the Electricity Industry). The current patchwork of national initiatives and subsidies means most of this will be focused on renewables, which are intermittent sources of power generation that require backup. However, the market-based power production required to provide this backup – e.g. combined cycle plant, coal/gas-fired plant, and traditional thermal capacity – is not being incentivised, while the CO2 scheme has all but collapsed, with prices now at a level where they are driving little investment.

Sending the right signals

To put a long-term asset into construction and operation, a reasonable level of regulatory and market certainty is required such that making an investment is going to have a rate of return over that 30+ year lifetime. However, current regulatory signals given by European and national policymakers make it difficult for investors to see a long-term return on investment, which is causing the market to stagnate.

Investing in gas is not attractive because gas prices are being driven up by high demand from Asia. At the same time, investing in coal-fired plant is difficult because it’s not clear what will happen with the carbon price or future possible taxation on emissions. In addition, many of the combined cycle plants in Europe average less than 30 per cent of their potential run-time, so it’s no surprise that investors remain reticent.

Long-term planning for green technologies is also being held back due to changes in the agreed political framework. The recent back loading of allowances by the European Commission to increase carbon prices is cited as a prime example. Although the third EU-ETS period 2013-2020 started on 1 January 2013, the amendment to change the volume of allowances released in the first years was tabled only two months before the end of 2012. Certainly, this is not going to improve planning security for power plant investors or operators.

Restoring the balance

The problem is that the political focus has been on renewables build out and meeting targets for each country, whereas the infrastructure necessary to sustain it is lagging behind. This is manifest in the pressures on internal balances within individual countries, and the situation is becoming critical as more intermittent power comes on stream.

Utilities don’t have control over when to dispatch intermittent power, while traditional thermal plants are closing down because they are not competitive. The result is more renewables and less thermal capacity as backup, creating a pressing challenge for TSOs and policy makers in terms of ensuring consistent stability in load at all times. This situation is compounded by the 2050 low carbon energy objective, because like renewables, low carbon energy means more volatility in terms of supply.

Although the industry is exploring a variety of options to ensure load stability and security, a viable solution is still some way off. Pumped-storage hydroelectricity for example, is fine for nations such as Sweden and Norway and their neighbouring countries, but huge storage resources would be needed to keep the lights on across Europe during the winter. Technology such as hydrogen storage is too dangerous, too expensive and too inefficient. Nuclear is a viable option but is being phased out by some countries, and winter in Europe is too dark for the region to rely on solar PV.

The move to low-carbon energy also creates a need to rebalance the transmission system. Current topology is set for large power stations in certain locations and the transmission of power from those power stations to the demand centres of the large cities and industrial areas. But with new power stations being offshore wind, distributed solar or distributed thermal plants, the feed-in of intermittent energy sources in areas where no consumption exists changes this topology. It also means conventional power plants are no longer operating at their design load for most of the time.

Unifying forces

Given that part load operation takes place at much less efficiency than plant design efficiency, interconnecting the EU grid to make it a ‘European copper plate’ would, among other solutions, reduce CO2 emissions though renewable energy sources and at the same time mitigate the increase in CO2 emissions from the back-up power plants vital for grid stability.

Here, TSOs and regulators need to be more proactive and work closely together to develop the critical physical interconnects between countries. Although there has been some progress, these types of project are by their nature complex and slow, as demonstrated by the length of time it has taken for the Spanish/French interconnector to enter construction. Nevertheless, delivery of the required physical interconnectivity would go a long way to realising the goal of a more efficient market and better investment signals.

A bigger physical interconnection system could possibly trigger, or at least put more political focus on aligning the fragmented subsidy schemes and systems within Europe. For example, there needs to be a decision taken at EU level to increase the CO2 price, while the industry would receive a huge boost from a return to demand growth, as this would ensure investment in additional thermal or dispatchable power plants.

Finally, it’s no secret that the EU is not immune to global activities. The major challenge today is to agree on how far the EU can carry the global climate change burden on its own without a binding global agreement on CO2 reduction. The issue is whether Europe can remain competitive as energy prices rise while other regions reduce them, especially if the ‘green economy’ does not materialise as hoped.

Globalisation dictates that multi-national firms will locate their sites where the workforce is best educated, and where labour and power costs are most competitive. Thus there is a need to focus more on fuelling the engine that generates wealth for Europe – i.e. the power industry – and this means ensuring we furnish the next-generation workforce with the skills and technical expertise necessary for Europe to compete on a global basis.

Europe aims to transform its power market through a more climate-friendly energy policy and more renewables, but this has to be enabled in the most cost-efficient way – namely with an appropriate price on CO2, and a single market by interconnectivity, by design, and by incentive scheme harmonisation. These are the issues driving the debate for the European power industry, and form the core pillars of the strategic track of the conference at this year’s POWER-GEN Europe conference, being held 4-6 June 2013 in Vienna.

Itronics successfully tests manganese recovery process

Itronics - a Nevada-based emerging cleantech materials growth company that manufacturers fertilisers and produces silver - has successfully tested two proprietary processes that recover manganese, with one process recovering manganese, potassium and zinc from paste produced by processing non-rechargeable alkaline batteries. The second recovers manganese via the company’s Rock Kleen Technology.

Manganese, one of the four most important industrial metals and widely used by the steel industry, has been designated by the US Federal Government as a "critical mineral." It is a major component of non-rechargeable alkaline batteries, one of the largest battery categories sold globally.

The use of manganese in EV batteries is increasing as EV battery technology is shifting to use of more nickel and manganese in battery formulations. But according to the US Department of Interior, there is no mine production of manganese in the United States. As such, Itronics is using its Rock Kleen Technology to test metal recoverability from mine tailings obtained from a former silver mine in western Nevada that has a high manganese content. 

In a statement, Itronics says that its Rock Kleen process recovers silver, manganese, zinc, copper, lead and nickel. The company says that it has calculated – based on laboratory test results – that if a Rock Kleen tailings process is put into commercial production, the former mine site would become the only primary manganese producer in the United States.

Itronics adds that it has also tested non-rechargeable alkaline battery paste recovered by a large domestic battery recycling company to determine if it could use one of its hydrometallurgical processes to solubilize the manganese, potassium, and zinc contained in the paste. This testing was successful, and Itronics was able to produce material useable in two of its fertilisers, it says.

"We believe that the chemistry of the two recovery processes would lend itself to electrochemical recovery of the manganese, zinc, and other metals. At this time electrochemical recovery has been tested for zinc and copper,” says Dr John Whitney, Itronics president. 

“Itronics has been reviewing procedures for electrochemical recovery of manganese and plans to move this technology forward when it is appropriate to do so and has acquired electro-winning equipment needed to do that.

"Because of the two described proprietary technologies, Itronics is positioned to become a domestic manganese producer on a large scale to satisfy domestic demand. The actual manganese products have not yet been defined, except for use in the Company's GOLD'n GRO Multi-Nutrient Fertilisers. However, the Company believes that it will be able to produce chemical manganese products as well as electrochemical products," he adds.

Itronics’ research and development plant is located in Reno, about 40 miles west of the Tesla giga-factory. Its planned cleantech materials campus, which will be located approximately 40 miles south of the Tesla factory, would be the location where the manganese products would be produced.

Panasonic is operating one of the world's largest EV battery factories at the Tesla location. However, Tesla and other companies have announced that EV battery technology is shifting to use of nickel-manganese batteries. Itronics is positioned and located to become a Nevada-0based supplier of manganese products for battery manufacturing as its manganese recovery technologies are advanced, the company states.

A long-term objective for Itronics is to become a leading producer of high purity metals, including the U.S. critical metals manganese and tin, using the Company's breakthrough hydrometallurgy, pyrometallurgy, and electrochemical technologies. ‘Additionally, Itronics is strategically positioned with its portfolio of "Zero Waste Energy Saving Technologies" to help solve the recently declared emergency need for domestic production of Critical Minerals from materials located at mine sites,’ the statement continues.

The Company's growth forecast centers upon its 10-year business plan designed to integrate its Zero Waste Energy Saving Technologies and to grow annual sales from $2 million in 2019, to $113 million in 2025.
