Philippines Increases Carbon Emission Reduction Target To 75%

0

The Philippines said that under its commitment to the Paris Agreement on Climate Change, it was revising its target to cut greenhouse gas emissions to a 75% reduction by 2030. This is up from a target of 70% set four years ago.

As prescribed by the Paris Agreement, 72.29% is conditional on the support of climate finance, technologies and capacity development provided by developed countries. The remaining 2.71 per cent of the target has to be implemented mainly through domestic resources.

The aim of the Paris Agreement which came into force in 2016 is to transform the world’s fossil-fuel-driven economy within decades and slow the pace of a global temperature increase to well below 2 degrees Celsius.

In 2017, the Philippines had ratified the agreement allowing Manila access to the Green Climate Fund, which aims to channel billions of dollars to help poor nations tackle global warming.

Global Carbon Dioxide Emissions Are Set For Their Second-Biggest Increase In History

0

New IEA report sees global energy-related CO2 emissions rising by 1.5 billion tonnes in 2021, driven by a strong rebound in demand for coal in electricity generation

Global energy-related carbon dioxide emissions are on course to surge by 1.5 billion tonnes in 2021 – the second-largest increase in history – reversing most of last year’s decline caused by the Covid-19 pandemic, a new IEA report released today shows. This would be the biggest annual rise in emissions since 2010, during the carbon-intensive recovery from the global financial crisis.

The IEA’s Global Energy Review 2021 estimates that CO2 emissions will increase by almost 5% this year to 33 billion tonnes, based on the latest national data from around the world as well as real-time analysis of economic growth trends and new energy projects that are set to come online. The key driver is coal demand, which is set to grow by 4.5%, surpassing its 2019 level and approaching its all-time peak from 2014, with the electricity sector accounting for three-quarters of this increase.

“Global carbon emissions are set to jump by 1.5 billion tonnes this year – driven by in the resurgence of coal use in the power sector. This is a dire warning that the economic recovery from the Covid crisis is currently anything but sustainable for our climate,” said Fatih Birol, the IEA Executive Director. “Unless governments around the world move rapidly to start cutting emissions, we are likely to face an even worse situation in 2022. The Leaders Summit on Climate hosted by US President Joe Biden this week is a critical moment to commit to clear and immediate action ahead of COP26 in Glasgow.”

Global energy demand is set to increase by 4.6% in 2021 – led by emerging markets and developing economies – pushing it above its 2019 level. Demand for all fossil fuels is on course to grow significantly in 2021, with both coal and gas set to rise above their 2019 levels. Oil is also rebounding strongly but is expected to stay below its 2019 peak, as the aviation sector remains under pressure.

The expected rise in coal use dwarfs that of renewables by almost 60%, despite accelerating demand for renewables. More than 80% of the projected growth in coal demand in 2021 is set to come from Asia, led by China. Coal use in the United States and the European Union is also on course to increase but will remain well below pre-crisis levels.

Electricity generation from renewables is set to leap by over 8% in 2021, accounting for more than half of the increase in overall electricity supply worldwide. The biggest contribution to that growth comes from solar and wind, which are on track for their largest annual rise in history. Electricity generation from wind is projected to grow by 275 terawatt-hours, or around 17%, from last year. Electricity generation from solar PV is expected to increase by 145 terawatt-hours, up almost 18% from last year. Their combined output is on track to reach more than 2 800 terawatt-hours in 2021.

Renewables are set to provide 30% of electricity generation worldwide in 2021, their biggest share of the power mix since the beginning of the Industrial Revolution and up from less than 27% in 2019. China is expected to account for almost half of the global increase in electricity generation from renewables, followed by the United States, the European Union and India.

The Global Energy Review is the IEA’s annual update on the latest trends in world energy and CO2 emissions. It covers all the main fuels and technologies, providing insights across regions, economies and countries.  

Fraunhofer ISE Sets New World Record of 26 Percent Efficiency for Both-Sides-Contacted Solar Cell

0

A team of researchers led by Dr. Armin Richter of the Fraunhofer Institute for Solar Energy Systems ISE achieved a record conversion efficiency of 26.0 percent for both-sides contacted silicon solar cells. In the recently published Nature Energy article “Design Rules for High-Efficiency Both-Sides-Contacted Silicon Solar Cell with Balanced Charge Carrier Transport and Recombination Losses” Download [nature.com], Richter explains the structure of the record-breaking cell and presents fundamental design-related aspects leading to even higher efficiencies. The design of the back-side cell surface as a full-area charge-carrier collecting passivating contact was key to the success.

TOPCoRE solar cell
© Fraunhofer ISEThe TOPCoRE solar cell achieved 26 percent efficiency, a new world record for both-sides-contacted solar cells.

With a share of over 90 percent, solar cells made of crystalline silicon dominate the global photovoltaic market. Thanks to technological advances in recent years, their efficiency has already come very close to the theoretical efficiency limit of crystalline silicon (29.4 percent). Previously, record efficiencies of around 26 percent were limited to solar cells with both metal contacts at the rear, the so-called interdigitated back contact, or IBC, solar cells. Both-sides-contacted solar cells, however, have been established as the industry standard and have become the preferred choice in industrial production due to their lower complexity.

With a new approach for both-sides contacted cells, the solar cell researchers at Fraunhofer ISE show that it is also possible to achieve the highest efficiencies for this type of solar cell.

The basis for the record cell is the TOPCon technology (Tunnel Oxide Passivating Contact). Developed at Fraunhofer ISE, this technology combines the advantages of very low surface recombination losses with efficient charge carrier transport. While industrial standard cells have a pn junction on the front side, the pn junction in the record cell was formed on the back side as a full-surface TOPCon contact. Thus, the full-surface boron doping on the front side was no longer required so that only a local boron diffusion directly under the front-side contacts was implemented.

This TOPCoRE cell (TOPCon Rear Emitter Solar Cell) allows higher voltages and higher fill factors than cells with a collecting emitter on the front side.

With this cell design, the wafer can be better utilized for charge carrier transport and the front side is more effectively passivated, for which aluminum oxide is used.

Detailed power loss analysis shows that this cell generally compensates for and minimizes both electron and hole transport losses as well as transport and recombination losses.

“Based on a systematic simulation-based analysis, we were able to derive some fundamental design rules for future high-efficiency silicon solar cells above 26 percent efficiency. Both-sides-contacted solar cells have the potential to reach efficiencies up to 27 percent and thus surpass the previous world record for silicon solar cells,” explains Prof. Stefan Glunz, Division Director of Photovoltaics Research at Fraunhofer ISE.

This cell structure, developed at Fraunhofer ISE, has a major advantage in that the subsequent production step – connecting the solar cells to form a module – can be based on existing technologies, thus allowing the use of many standard techniques.

LONGi, the world leading solar technology company, has announced a cooperation with PowerField, its partner in the Netherlands, to deploy 15.49MW of its Hi-MO 4  modules at Ter Apelkanaal, one of three production locations of the Dutch potato starch producer Royal Avebe. As a result of a joint collaboration between Royal Avebe and PowerField, a 10-hectare park has been built and, exclusively equipped with over 34,000 LONGi modules, was connected to the grid earlier this month.

Royal Avebe’s sustainable ambitions are clear: to save energy and make the energy it uses greener. It is estimated that the capacity of the Ter Apelkanaal park will provide for the electricity needs of more than 4,000 households annually and reduce CO2 emissions by nearly 8,000 tons.

“We have several large factories surrounded by a lot of land, but we didn’t make use of all the space,” commented Barbara Huneman, Royal Avebe’s director of Energy & Public Affairs. “So we could easily build a solar park there, our goal being to install solar panels at all our production locations and offices. In this way, we are working towards 2050, the year in which we have to be completely CO2 neutral.”

Ter Apelkanaal is the second project that PowerField is operating itself. “It is really good that we can transform land that is not suitable for agricultural use into a solar park. In this way we make good use of the available space and help organizations such as Royal Avebe with their sustainable plans,” added Ivo van Dam, PowerField’s Chief Technology Officer. “The cooperation with LONGi was very smooth. Even considering our high quality and CSR standards, they were able to meet our requirements with ease.”

“LONGi is delighted to cooperate with PowerField to develop sustainable and green solar parks in the Netherlands. We have made significant progress in the DG (Distributed Generation) market with our Dutch partners since 2018. We are confident in supplying our state-of-the-art modules to the owners of large-scale ground-mount  projects and together move towards the country’s sustainable development goals,” commented Dennis She, Senior Vice President at LONGi Solar.

As of the end of 2020, LONGi’s market share in the Netherlands stands at an impressive 20%. The Dutch market is typically dominated by DG and, with increasing annual demand of 2.5~3 GW, it has a mature structure and ranks among the top five markets in Europe. The Netherlands is an indispensable part of LONGi’s presence in Europe, underlined by its European warehousing center being located in Rotterdam, home of Europe’s largest seaport.
