Implicit in the EUâs plans, announced in July, to be the worldâs Hydrogen leader is that this technology will have others competing for the top spot too. When EU nations ramped up their solar PV sector in the 2000s they couldnât survive the arrival and rapid expansion of Chinese production. Will EU Hydrogen meet the same fate? Sören Amelang at CLEW speaks to a wide range of experts to try to answer this vital question from all the relevant … [Read more...]
The new era of electricity needs modern ways to charge customers
Todayâs technologies â wind, solar, storage - have widely differing cost and operating characteristics to fossil fuels. So the way customers are made to cover those costs â assigning different rates to different customer classes â should change. Jim Lazar and Mark LeBel at RAP explain why and how, referencing their comprehensive manual âElectric Cost Allocation for a New Eraâ. They describe how the full range of technologies now establishing … [Read more...]
Floating Solar: can it help ASEAN reverse coalâs continued rise?
Floating solar farms may be gaining traction in Asia. Capacity is still small: by 2019 the big players Japan and China had a combined floating photovoltaic (FPV) installed capacity of 1.3GW. But the ASEAN countries that had virtually nothing before 2019 now have over 51MW and have planned in another 858MW. A report by Sara Jane Ahmed and Elrika Hamdi at IEEFA explains why FPV is looking better and cheaper at balancing out peaks and troughs than … [Read more...]
Three U.S. utilities to skip the gas âbridgeâ, move straight from coal to renewables
At the end of June, utilities in three U.S. states declared they are closing down coal plants and moving straight to renewables, without building new gas plants as a âbridgeâ fuel. For example, to replace lost coal capacity, Tucson Electric Power in Arizona will add 2,457MW of new wind and solar generation, backed up with 1,400MW of battery storage. Similar commitments are being made by other utilities in Colorado and Florida. New Mexico is … [Read more...]
BPâs world energy review: 2019 saw clean electricity match coal
Simon Evans at Carbon Brief summarises BPâs 69th edition of its influential annual statistical review of world energy, looking at 2019. Overall, total energy demand rose, though slower than usual. Renewables were the largest source of new energy, but were closely followed by oil and gas. Coal use dropped again, the fourth drop in six years, thanks to historic declines in the EU and the US. But continued growth in SE Asia, China and India leaves … [Read more...]
The PAC Scenario: net-zero by 2040 to meet Europeâs Paris goals
The EU is not on track to meet its Paris Agreement obligations on emissions and limiting the global temperature rise to 1.5°C. CAN Europe and the European Environmental Bureau (EEB) present their Paris Agreement Compatible (PAC) scenario, designed to do just that. Itâs been created through the careful analysis of contributions from more than 150 stakeholders including NGOs, scientists, industry and grid operators. Jörg MĂŒhlenhoff at CAN Europe … [Read more...]
âGreenâ chemical plants that ramp up and down with wind, solar
One solution to variable renewables is to create customers that have no problem with ramping up and down production along with the power. In fact, when the wind and solar is producing too much power for the grid it can be bought very cheaply, making intermittent customers very happy. Jim Conca describes a new design for a Chlor-Alkali Chemical Plant that can âidleâ without critical components of the plant degrading â the main reason for a plant … [Read more...]
Germanyâs Corona stimulus package: whatâs in it for energy, climate?
âŹ30bn of Germanyâs âŹ130bn Corona economic stimulus package is dedicated to the energy sector and the climate. Simon Göss at Energy Brainpool runs through the four main areas of focus. Thereâs âŹ11bn to fund a reduction in the EEG levy (renewables surcharge) to help electricity consumers. âŹ9bn goes to creating a hydrogen industry for Germany. Thereâs âŹ7bn to promote e-mobility (tax exemptions, subsidies, co-financing of charging stations and … [Read more...]
Tipping Points reached for Solar, Wind, Batteries, EVs. What of the other Clean Energy techs?
History shows a disruptive technologyâs tipping point can be under 5% of market share, thatâs all it takes. The number of horses in use peaked in the U.S. once car ownership reached 3%. Gas lighting in the UK peaked with electric lighting at just 2% of the market. Landline phones in the U.S. fell precipitously after mobiles captured 5% of the market. Ji Chen and Koben Calhoun at RMI argue the tipping point has already been passed for solar, wind, … [Read more...]
Grid-scale Solar PV storage can use re-purposed old EV batteries
Once an EV battery has declined to 80% of its original capacity it is considered too weak for continued vehicle use. Recycling the battery â at that point - to make another one is expensive. MITâs David Chandler describes how researchers there have run experiments and models to show that old EV batteries can instead be packed together and used as backup storage for grid-scale solar PV installations. Itâs cheaper than building new Li-ion battery … [Read more...]
10,000 sq km of Solar in the Sahara could provide all the worldâs energy needs
A little over 10 years ago David MacKay drew attention by saying âAll the worldâs power could be provided by a square 100km by 100km area in the Sahara.â Furthermore, MacKayâs calculation of the full potential of the regionâs Concentrated Solar Power (CSP) totalled 25 times the TWh/year the world uses today. That was looking at the Middle East and North Africaâs (MENA) high solar irradiance, ample available land and the technologies of the day. … [Read more...]
Energy Post panel discussion – Cross-Border Capacity [VIDEO]
Whilst renewable generation continues to grow, cross-border capacity fails to keep up. On May 19, 2020, Energy Post hosted a unique panel qualified to discuss the issue and shed some light on how we got here and what the options might be going forward. The discussion was moderated by Erik Rakhou - alternate member of the ACER board of appeal and consultant at Baringa. Representing the European Commission was Florian Ermacora and for independent, … [Read more...]
Negative electricity prices: lockdown’s demand slump exposes inflexibility of German power
The lockdown has unexpectedly allowed us to model certain aspects of the energy sectorâs possible future. One is the oversupply of variable renewables into the grid. In Germany, a slump in demand plus an exceptionally sunny and windy few months sent wholesale electricity prices negative and to record lows. Fossil generators calculated that paying buyers to take electricity was cheaper than performing a shut-down re-start sequence, so they did … [Read more...]
Clean Energy threatened by lockdown of critical minerals supply
Clean energy technologies depend on the reliable and growing supply of critical minerals and metals, far more so than the old fossil fuel world. An EV uses five times the quantity needed by a conventional car, and an onshore wind plant requires eight times that of a gas-fired plant of the same capacity. Hence, electric transport and grid storage are now the largest consumers of lithium and cobalt. Examples of rising consumption abound for other … [Read more...]
Europeâs Unprecedented Opportunity to usher in a Green Economy
While the COVID-19 pandemic is singular in its rapid development and global implications, many have drawn parallels with another, equally significant, global issue: the ongoing climate crisis. In Europe, in particular, the parallels have led to the realization that the European Unionâs COVID-19 response may also hold the key to addressing and accelerating longer-term decarbonization goals. Unlike COVID-19, the climate crisis is slow-burning, … [Read more...]
