The in-depth study, which analyses hydrogen’s current state of play and offers guidance on its future development, is being launched by Dr Fatih Birol, the IEA’s Executive Director, alongside Mr Hiroshige Seko, Japan’s Minister of Economy, Trade and Industry, on the occasion of the meeting of G20 energy and environment ministers in Karuizawa, Japan.

Hydrogen can help to tackle various critical energy challenges, including helping to store the variable output from renewables like solar PV and wind to better match demand. It offers ways to decarbonise a range of sectors (including long-haul transport, chemicals, and iron and steel) where it is proving difficult to meaningfully reduce emissions. It can also help to improve air quality and strengthen energy security.

A wide variety of fuels are able to produce hydrogen, including renewables, nuclear, natural gas, coal and oil. Hydrogen can be transported as a gas by pipelines or in liquid form by ships, much like liquefied natural gas (LNG). It can also be transformed into electricity and methane to power homes and feed industry, and into fuels for cars, trucks, ships and planes.

To build on this momentum, the IEA report offers seven key recommendations to help governments, companies and other stakeholders to scale up hydrogen projects around the world. These include four areas:

  • Making industrial ports the nerve centres for scaling up the use of clean hydrogen;
  • Building on existing infrastructure, such as natural gas pipelines;
  • Expanding the use of hydrogen in transport by using it to power cars, trucks and buses that run on key routes;
  • Launching the hydrogen trade’s first international shipping routes.

 

The report notes that hydrogen still faces significant challenges. Producing hydrogen from low-carbon energy is costly at the moment, the development of hydrogen infrastructure is slow and holding back widespread adoption, and some regulations currently limit the development of a clean hydrogen industry.

Today, hydrogen is already being used on an industrial scale, but it is almost entirely supplied from natural gas and coal. Its production, mainly for the chemicals and refining industries, is responsible for 830 million tonnes of CO2 emissions per year. That’s the equivalent of the annual carbon emissions of the United Kingdom and Indonesia combined.

Reducing emissions from existing hydrogen production is a challenge but also represents an opportunity to increase the scale of clean hydrogen worldwide. One approach is to capture and store or utilise the CO2 from hydrogen production from fossil fuels. There are currently several industrial facilities around the world that use this process, and more are in the pipeline, but a much greater number is required to make a significant impact.

Another approach is for industries to secure greater supplies of hydrogen from clean electricity. In the past two decades, more than 200 projects have started operation to convert electricity and water into hydrogen to reduce emissions.

Expanding the use of clean hydrogen in other sectors – such as cars, trucks, steel and heating buildings – is another important challenge. There are currently around 11,200 hydrogen-powered cars on the road worldwide. Existing government targets call for that number to increase dramatically to 2.5M by 2030.

Policy makers need to make sure market conditions are well adapted for reaching such ambitious goals. The recent successes of solar PV, wind, batteries and electric vehicles have shown that policy and technology innovation have the power to build global clean energy industries.

The overall renewable power capacity in Brazil is expected to grow at a compound annual growth rate (CAGR) of 6% from 31 GW in 2018 to 60.8GW in 2030, according to GlobalData.

GlobalData’s latest report: “Brazil Power Market Outlook to 2030, Update 2019 – Market Trends, Regulations, and Competitive Landscape” reveals that increased renewable energy auctions, promotion of hybrid renewable energy projects and other government initiatives such as tax incentives, smart metering, renewable energy targets and favorable grid access policies for renewable energy are likely to result in renewable expansion by 2030.

Between 2019 and 2030, solar PV and onshore wind segments are expected to grow at CAGRs of 14% and 6%, respectively. The significant rise in these two technologies will result in renewable energy being the second largest contributor to the country’s energy mix by 2030.

The connection of over 25,000 power systems, mostly solar PV systems to the Brazilian grid in mid-2018 under the net metering scheme, further underpins the renewable growth pattern over the forecast period.

The main challenges for Brazil’s power sector are its overdependence on cheap hydropower for base-load capacity and lack of a robust power grid infrastructure. In 2018, hydropower accounted for 62.7% of the country’s total installed capacity. In case of a drought, depletion of dam reservoirs could result in power shortages and switching over to costly thermal power which will increase the electricity prices.

In the long term, hydropower capacity is expected to decline and be compensated with increased renewable power capacity. On the other hand, thermal and renewable capacities are slated to increase and contribute 28% and 18%, respectively of the installed capacity in 2030.

Brazil is moving towards a balanced energy mix as it prepares to double its non-hydro renewable power capacity by 2030. With an almost 10GW increase in thermal power capacity by 2030 compared to 2018, the country is on course to better manage peak demand, reduce dependence on hydropower and maintain a healthy grid.

The Energy Division of Acciona has developed a pioneering solution at global level in the field of hybridization between wind and photovoltaic power. It consists of covering a wind turbine tower with flexible organic panels to produce energy for the internal electricity consumption of the turbine. The innovative project will allow the study of the performance of the organic panels -an emerging photovoltaic technology- and their application to improve wind turbine efficiency.

The system has been installed in one of the turbines of the Breña Wind Farm (Albacete, Spain), which ACCIONA owns and operates. The turbine is an AW77/1500 of Nordex-Acciona Windpower technology, mounted on an 80-metre-high steel tower (hub height).

Installed on the tower are 120 solar panels facing southeast-southwest to capture the maximum of the sun’s rays throughout the day. They are distributed at eight different heights, occupying around 50 metres of the tower’s surface area. The photovoltaic modules, with an overall capacity of 9.36 kWp, are of Heliatek technology (HeliaSol 308-5986 model). They are only 1 mm thick, and each one has a surface area of 5,986 x 308 mm.

In contrast to the conventional technology used in the manufacture of photovoltaic models based on silicon, these organic panels use carbon as raw material and are characterized by their structural flexibility, which makes them adaptable to very different surfaces. Other key features are lower maintenance costs, less energy consumption during manufacture, easier logistics and the complete recycling of the materials used, although their efficiency is still below that of silicon modules.

The hybridization project in Breña means the optimization of the use of space for renewable energy production and it will enable us to test the efficiency of organic photovoltaics, a technology that we believe has one of the best improvement curves in terms of technological efficiency. That is why we have decided to pilot it”, says Belén Linares, Energy Innovation Director in Acciona.

Optimizing generation

The immediate application of the Breña project is to produce part of the energy that the internal systems of the wind turbine need. When the turbine is running, some of the energy generated is used to power the auxiliary systems. In shutdown mode, certain systems need to continue functioning so they are fed from the grid, which means that the wind turbine is registering a net consumption of energy.

The new photovoltaic system with panels on the tower will be able to cover, completely or partially, the energy demand related to the operation of the wind turbine when there is solar radiation, or even -in a possible later phase of the project- when the sun is not shining. This would be done through a battery storage system, leading to an improvement in the net production sent to the grid.

The organic panels are connected to two inverters that convert DC into AC for later connection to the grid which supplies the electrical equipment of the wind turbine.

The entire system is monitored with a view to evaluating it under real conditions, both from the point of view of energy production and degradation of the solar modules. Conceptually, it is a very innovative design in relation to previous experiences in wind power-photovoltaic hybridization, based on panels installed on the ground.

The idea is part of a wide-ranging innovation project driven by Acciona to study a number of emerging photovoltaic technologies, with the aim of pioneering the adoption of more efficient solutions in each case and consolidating its leadership as a PV developer. The company currently has over 1,200 MWp in operation or under construction in different parts of the world.
