Despite widespread expectations of another increase, global energy-related carbon dioxide emissions stopped growing in 2019, according to last IEA data. After two years of growth, global energy-related CO2 emissions were unchanged at 33 Gt in 2019 even as the world economy expanded by 2.9%. This was primarily due to a sharp decline in CO2 emissions from electricity generation in advanced economies, thanks to the expanding role of renewable sources (mainly wind and solar), fuel switching from coal to natural gas and higher nuclear power generation. Other factors included milder weather in several countries and slower economic growth in some emerging markets…

The basic configuration of electrical power systems for industrial, commercial and residential applications has altered little for decades. But now disruptive new technologies (hybridisation and power conversion) are about to bring big changes. And one major advantage is that these innovative solutions can benefit from technologies already existing in the market, tried and tested in hundreds of applications. This is the case of the hybrid power system inverters from Danfoss which, by applying a mature technology – that of variable speed drives -, are able to convert AC to DC and vice versa as required by hybrid power systems, in compliance with international grid codes…

Hybrid systems integrating PV and diesel generators are a solution for those sites that need cost-efficient energy, and provide significant benefits to the consumption of energy from the local grid. But these systems can provide more benefits to users when combined with energy storage systems (ESS). The German company, Qinous, a system integrator of smart plug and play ESSs and Danfoss Drives have built numerous ESS installations together around the globe. Typically, these sites are located off-grid, and their purpose is to optimise the local energy production: solar PV generation and diesel generators. This article offers two examples of this type of installation, as well as the benefits they bring users…

Despite widespread expectations of another increase, global energy-related carbon dioxide emissions stopped growing in 2019,according to IEA data just released. After two years of growth, global emissions were unchanged at 33 Gt in 2019 even as the world economy expanded by 2.9%. This was primarily due to declining emissions from electricity generation in advanced economies, thanks to the expanding role of renewable sources (mainly wind and solar), fuel switching from coal to natural gas, and higher nuclear power generation. Other factors included milder weather in several countries, and slower economic growth in some emerging markets.

A significant decrease in emissions in advanced economies in 2019 offset continued growth elsewhere. The United States recorded the largest emissions decline on a country basis, with a fall of 140 Mt, or 2.9%. US emissions are now down by almost 1 Gt from their peak in 2000. Emissions in the European Union fell by 160 Mt, or 5%, in 2019 driven by reductions in the power sector. Natural gas produced more electricity than coal for the first time ever, meanwhile wind-powered electricity nearly caught up with coal-fired electricity. Japan’s emissions fell by 45 Mt, or around 4%, the fastest pace of decline since 2009, as output from recently restarted nuclear reactors increased. Emissions in the rest of the world grew by close to 400 Mt in 2019, with almost 80% of the increase coming from countries in Asia where coal-fired power generation continued to rise.

Across advanced economies, emissions from the power sector declined to levels last seen in the late 1980s, when electricity demand was one-third lower than today. Coal-fired power generation in advanced economies declined by nearly 15% as a result of growth in renewables, coal-to-gas switching, a rise in nuclear power and weaker electricity demand.

The irruption of the electric vehicle is unstoppable. In the urban environment, for the few kilometres travelled, the availability of public charging points and proximity to the usual charging point (at home or the office), supplying the vehicle with electricity is a simple question. It is thus worth asking what is the reality and the future of the electric vehicle in interurban journeys. The answer lies in their autonomy and the availability of interurban charging points. In this segment, as with private charging, Iberdrola is well-placed as one of the key players when facilitating access to e-mobility. Through the Iberdrola Green Charging Network, the company is positioning itself as the driver of e-mobility in Spain as well as in the field of public charging for electric vehicles, spearheading the technological change with 100% renewable energy…

2019 will not down in history as the year in which progress was made to put into practice the ideas to which we have fortunately committed as regards energy and sustainability, after years of darkness such as those experienced between 2010 and mid-2018. We will never understand why this has not been achieved, where there is a majority agreement of ideas and proposals, the different political parties have been incapable of achieving the consensus demanded by society. It is an absolute failure of dialogue and commitment, which we will never forget, forget, as there has never been a more favourable environment as this year in which to achieve it… By Fernando Ferrando. Chair of the Fundación Renovables.

Ingeteam is finalizing the launch of its latest INGECON® SUN STORAGE 1Play TL M hybrid inverter. This highly versatile solar inverter features a battery input and two more inputs for PV modules. Each PV input has its own maximum power point tracking system, making it ideal for harnessing the maximum amount of energy on roof-mounted, self-consumption PV installations, with the PV modules positioned in two different orientations.

A further advantage is that the INGECON® SUN STORAGE 1Play TL M hybrid inverter features an EMS (Energy Management System), making it possible to implement advanced operating modes, such as self-consumption, and facilitating system monitoring through the INGECON® SUN Monitor smartphone application. Moreover, there is an application to easily and remotely set-up and upgrade the inverter firmware via PC, tablet or mobile phone. Moreover, the system commissioning and the inverter’s firmware update can be performed remotely with the application via PC, tablet or smartphone.

This new inverter is suitable for both grid-connected and stand-alone systems. In this latter case, the hybrid inverter is responsible for generating the grid. For grid-connected systems, the inverter features a back-up functionality so that, in the event of a grid outage, the critical loads can be powered from the batteries and PV panels.

Just like the previous model, this new hybrid inverter by Ingeteam is compatible with lead-acid and lithium-ion batteries, and is also compatible with the storage systems made by the market’s leading manufacturers.

Production of this new inverter is set to start in May and it will be available with two power outputs: 3 kW and 6 kW.

The first units of the INGECON® SUN STORAGE 1Play TL M will be showcased on the stands of Ingeteam’s main distributors during the GENERA fair to be held at the IFEMA exhibition grounds in Madrid, from 5th to 7th February.

The Power-to-Gas (PtG) technology converts electric energy into hydrogen or, by subsequent synthesis, into methane or liquid energy carriers. An analysis of Ludwig-Bölkow-Systemtechnik’s(1) PtG database shows that more than 300 PtG projects have been announced worldwide by the end of 2019. During the last 6 months, more construction capacity has been announced than in the last 6 years altogether.

At the same time, PtG systems have increased in size. Several electrolysers with an electrical capacity of more than 30 MW will be built in Germany in the next few years. The projects focus on sector coupling in particular, using hydrogen technologies. Sector coupling links the electricity, heat, and gas sectors as well as the mobility sector and enables a better balancing of fluctuations in renewable energies and CO2-reduced mobility.

Larger plants are also in the planning process in neighbouring countries. However, Germany is assuming a pioneering role, particularly with its “living labs” (within the 7th Energy Research Programme of the Federal Government). Here, hydrogen technologies are used and tested under real conditions at an industrial scale, focusing on regions with a high supply of renewable energies or important industrial sites pursuing particularly attractive concepts.

The Federal Government also supports other H2 regions in Germany in the context of the “HyLand” funding program. In December 2019, 13 “HyExpert” regions and three “HyPerfomer” – regions were selected for the development of H2 concepts and the implementation of specific project concepts.

In addition to using it as an energy carrier, hydrogen is versatile feedstock used, for example, in the chemical, petrochemical, and metal industries. Presently, about 50 million Nm³ of hydrogen day are used in German industry, which is largely produced from fossil sources (“grey” hydrogen), mainly from natural gas. Over 20 million tons of carbon dioxide (CO2) are being released annually as a result. When hydrogen is produced via electrolysis from renewable electricity (“green” hydrogen), no CO2 is emitted. Consequently, German CO2 emissions can be significantly reduced by substituting grey hydrogen by green hydrogen.

Green hydrogen will become competitive in the long run

Today environmentally friendly green hydrogen is even more expensive than grey hydrogen. However, costs are expected to reach parity as a result of improved political and regulatory conditions and declining costs of renewable electricity and electrolysis systems. Applications of the hydrogen produced by PtG include feeding hydrogen into the natural gas grid, with or without prior methanation, employing green hydrogen for direct reduction in steel production and hydrogenation in refineries, and using it in the transport and the heating sector.

The World Future Energy Summit 2020 kicked off at the Abu Dhabi National Exhibition Center in United Arab Emirates on January 14, 2020 with the theme of “Rethinking Global Consumption, Production and Investment”. Hosted by Masdar, the Summit keynotes were presented by heads of states, members of the GCC royal families, global decision makers of clean energy enterprises and industry experts from all over the world.

At the Future Sustainability Summit, Li Zhenguo, Founder and President of LONGi, delivered a keynote speech which discussed various issues such as the development of new energy, the industry trends of future energy technology, global energy policies, cooperation in R&D and the pursuit of the best renewable energy solutions.

“With the development of the global economy, clean energy plays an important role in our daily life. We firmly believe that ‘Photovoltaic + Energy Storage’ is the ultimate energy solution for the future, and a powerful force in the fight against climate change and to achieve sustainable development,” said Li Zhenguo, Founder and President of LONGi. “With continuous technology innovations, we believe that solar energy will become the most economical power source in most regions of the world in the next 2-3 years. When the cost reaches parity, the transition of traditional energy to clean energy will begin on a large scale.”

“In the Middle East, water and agriculture are constrained by ecological and environmental elements. The use of solar power could solve the problems of electricity and energy consumption, and greatly reduce the cost of seawater desalination. Once there is sufficient fresh water, the problems of agriculture and food shortages will be eliminated. This is the benefit Solar for Solar brings. ” Li Zhenguo added.

At the summit, LONGi showcased its new generation high-efficiency Hi-MO 4 modules with the new 166mm M6 standard wafers at World New Energy Summit & Exhibition. LONGi aims to accelerate the development of renewable and clean energy technologies in the Middle East region with excellent power generation performance and high efficiency. Utility scale applications of LONGi Hi-MO 4 have seen significant savings in labor and BOS costs, and has gained wide acceptance from local customers.

LONGi further announced in WFES that it is selected as the sole Photovoltaic Sponsor for the China Pavilion at Expo 2020 Dubai UAE. As the world’s leading solar technology company, LONGi is committed to achieving the vision of low-carbon development with the application of photovoltaic products for seawater desalination, and desert treatment to reduce carbon emission and achieve a negative carbon earth.
