The flexibility of small scale solar can help roll out vaccines to remote and poorer parts of the world that the grid doesn’t reach. Access to power for refrigeration is vital when you consider that most vaccines must be stored between 2°C and 8°C, like for measles and polio. It’s the same for the Covid-19 vaccines from Johnson & Johnson and AstraZeneca-Oxford. But the Moderna vaccine must be stored at between -25°C and -15°C. The … [Read more...]
Outlook USA: even with battery costs, Wind and Solar can undercut Coal and Gas by 2023-24
IEEFA has published its U.S. Power Sector Outlook 2021. Its authors, Dennis Wamsted, Seth Feaster and David Schlissel summarise and explain the projections. They say that coal and gas are set to become the biggest losers as renewable generation climbs quickly. The future for wind and solar – coupled with storage to address intermittency - is looking very good. They present estimates from NextEra (the largest renewable energy developer in the … [Read more...]
Plastic Solar Cells: OPV power conversion efficiency now reaches 18%
Don’t just think plastics are insulators. Two Nobel prizes were won by showing they can be semiconductors. That celebrated research opened the door to polymer-based solar cells. They are made in a lab from common elements, using processes established decades ago for ordinary household items like plastic wrap. A design strategy breakthrough led by NREL has now created an organic photovoltaic (OPV) solar cell with a record-breaking 18.07% power … [Read more...]
Public opposition and grid integration costs: the two limiting factors for Wind?
Are we heading for an over-reliance on wind? With wind generation costs continuing to drop dramatically, Schalk Cloete takes a data-driven look at the obstacles wind will face as its contribution to the global energy mix (a little over 2% today) keeps rising. In the main, it is grid integration and public opposition to very visible turbines – and they are related. Putting turbines out of sight and offshore will increase transmission costs. And … [Read more...]
Understanding battery costs better: Li-ion costs have dropped 97% in 30 years
There are two revelations here. First, quite how dramatically lithium-ion battery costs have dropped since 1991 – by 97%. Second, that nobody could agree on how big that drop has been. Agreement on that number – and an established procedure to therefore make good forecasts - is vital for policy makers and related clean energy players. They need to know how much of a role batteries can play in the electrification of transport as well as storage … [Read more...]
“The Role of the EU ETS in Decarbonisation to 2030” [written summary of the panel discussion]
![“The Role of the EU ETS in Decarbonisation to 2030” [written summary of the panel discussion]](https://energypost.eu/wp-content/uploads/2021/03/BANNER-PGE-ETS-Mar-2021-500px-150x99.jpg)
Here you can read a summary of the online discussion from March 19th 2021 on the current debate over the review of the EU ETS. The full video is available here. Of primary concern for fossil-dependent lower income nations is the carbon price rising so high that it reduces available budget for investment in clean energy. If that happens there’s clearly a problem. The counter argument is that there are other funding mechanisms available, and more … [Read more...]
“The Role of the EU ETS in Decarbonisation to 2030” [Energy Post event video]
Here you can watch our video of the online discussion from March 19th 2021 on the current debate over the review of the EU ETS. Of primary concern for fossil-dependent lower income nations is the carbon price rising so high that it reduces available budget for investment in clean energy. If that happens there’s clearly a problem. The counter argument is that there are other funding mechanisms available, and more than one pathway for successful … [Read more...]
Saudi Arabia’s clean hydrogen plans for converting ambitions into action
The recent Memorandum of Understanding with Germany on clean hydrogen cooperation underlines Saudi Arabia’s ambition in becoming a global powerhouse producer in this field. Governments and industry players are currently considering clean hydrogen as an energy vector with key energy transition roles in an increasingly carbon-constrained world. Hydrogen has the potential to grow into a trillion-dollar commodity market, with enormous opportunities … [Read more...]
Do government renewable energy auctions squeeze the PPA market?
Spanish government renewable energy auctions in January produced record-breaking low strike prices for both wind and solar. For solar the average price was €24.47/MWh (the lowest was €14.98/MWh), guaranteed for 12 years through contracts-for-difference (CfDs). As such auctions continue around Europe, Michael Claußner at Energy Brainpool asks what impact these prices will have on future power prices in general and on solar power purchase agreement … [Read more...]
Are Regulations and Climate Activism the main driver for coal exits, not Gas and Renewables prices?
It’s widely thought in the media and politics that market forces are now the primary driver for the demise of coal: mainly natural gas prices, and the rising adoption and competitiveness of wind and solar. However, David Drake and Jeffrey York at the University of Colorado Boulder present their research from the U.S. that suggests the two main drivers are federal policy and climate activism. They studied the retirement of 348 coal-fired units … [Read more...]
Berkeley Lab releases progress report on state renewable energy standards
Berkeley Lab has released an annual status report on U.S. renewables portfolio standards (RPS), providing an overview of key trends associated with state RPS policies. The report, U.S. Renewables Portfolio Standards 2021 Status Update: Early Release, published in slide-deck form along with accompanying data files, describes recent legislative revisions, key policy design features, compliance with interim targets, past and projected impacts on … [Read more...]
EU Recovery funds: where is the support for District Heating?
District Heating is an efficient way to heat homes, particularly in a country like Latvia where 58% of its primary energy consumption is used for heating. But Selīna Vancāne at Riga City Council is very concerned that the draft EU Recovery plans do not include any support under the climate goals for district heating projects. Perhaps it’s because of a blind spot: most of Europe is prioritising individual heating units powered by electricity. … [Read more...]
New Berkeley Lab Report Documents Trends in System Impacts, Reliability and Market Value of Solar in the United States
By Andrew Mills and Joachim Seel, Berkeley Lab As solar generation increases, it is expected to progressively impact the bulk power system—changing prices for energy and other grid services. Solar generation is driven by sunshine and thus often highly correlated over the course of a day within a region. Without the deployment of storage or an increase in price-responsive load, growth in solar capacity is … [Read more...]
Germany’s Renewable Energy Act 2021: how to implement the fine policy detail of emissions reduction targets
After much haggling and debate, Germany’s Renewable Energy Act (EEG) 2021 was finally approved in December and came into force on 1 January 2021. Sila Akat and Simon Göss at Energy Brainpool outline the most important changes imposed by the amendment. It gives an insight into how a nation is dealing with the finer details of increasingly ambitious emissions reduction targets. The authors cover the main issues and outcomes. How Germany is dealing … [Read more...]
Optimising Wind and Solar needs new ways of weather forecasting
Weather forecasters are used to – and very good at – predicting large-scale weather patterns and then inferring what the actual surface weather conditions will be, based on a database of past events. Hannah Bloomfield at the University of Reading explains how the creation of a database of site-specific wind and solar generation, as well as grid demand, can be used it the same way to more accurately predict the impact of the weather on these … [Read more...]
