The worldâs commitment to hydrogen needs an assessment of which regions can make it the cheapest. Herib Blanco at IRENA and Jacopo de Maigret at Fondazione Bruno Kessler describe their study of the range of factors that affect the future cost and therefore the potential for clean renewable hydrogen, estimated for 2030 and 2050. The main drivers are the capital cost of the renewable generation and the electrolyser, the cost of capital, and the … [Read more...]
Russia-Ukraine: modelling the consequences for the European electricity market to 2050
Alex Schmitt, Christoph Kellermann, Calvin Triems and Huangluolun Zhou at Energy Brainpool have used their modelling tools to update their predictions of how the European electricity market will develop over the next 30 years, given a target of 99% emission-free generation in 2050. Projections are made on generation (mix and volumes) and price. The big change from their last predictions is the Russia-Ukraine war and Europeâs determination to ramp … [Read more...]
Manifesto: fit-for-purpose flexible grids for the clean electrification of Europe
The integration of new clean generation sources on top of the increase in electrification of industry, e-mobility, and heating and cooling means grid investment must be made a priority. Anything else will leave deployment-ready solutions waiting, slowing down the transition. The backdrop is that over one third of the EUâs grids are already more than 40 years old. Eurelectric has produced a manifesto, âConnecting The Dotsâ, that estimates … [Read more...]

How the U.S. can meet its target of halving emissions by 2030
Writing for Carbon Brief, John Bistline at the Electric Power Research Institute summarises his co-authored paper âActions for reducing US emissions at least 50% by 2030â, the target set by the Biden administration. The paper provides detailed projections and actionable insights about the policies and technology deployment needed to achieve this near-term climate goal. Roughly 70-90% of emissions reductions by 2030 must come from the power and … [Read more...]
Reversible Hydrogen fuel cells: can H2 gas-to-power support the grid economically?
We know about making green hydrogen from excess intermittent wind and solar. We also know that that same intermittency means the gaps in wind and solar generation need filling. Green hydrogen is very expensive to make. But what if that green hydrogen could be economically converted back to power when needed? Writing for Stanford University, Edmund Andrews describes new research, in collaboration with the University of Mannheim in Germany, into … [Read more...]
Electricity markets with high shares of Wind and Solar will need Nuclear
When electricity markets have high shares of wind and solar â the goal of many regions around the world â is it more efficient to build a nuclear power plant instead of investing further in more renewable capacity? The answer is yes, according to a study by Machiel Mulder, Xinyu Li and Arjen Veenstra at the University of Groningen. In essence, itâs because nuclear benefits from the high (scarcity) prices when thereâs little wind or sunshine. Here … [Read more...]
Latest U.S. modelling shows Battery Storage can support an 80% Renewables grid by 2050
NRELâs latest Storage Futures Study concludes that battery storage should be able to support an 80% renewables grid mix in the U.S. by 2050. Madeline Geocaris at NREL explains how they modelled hundreds of future scenarios to accurately represent the value of diurnal (<12 hours) battery energy storage. The high-storage scenarios made different cost and performance assumptions for storage, wind, solar PV, and natural gas. 15 storage … [Read more...]
Will Chinaâs gigantic wind and solar âbasesâ mean targets met four years early?
China will have doubled its 2020 installed wind and solar capacity by 2025, exceeding 1,100GW, according to government plans. Thatâs four years sooner than required to meet their target of peak CO2 emissions by 2030 and carbon neutrality before 2060. Writing for Carbon Brief, Lauri Myllyvirta and Xing Zhang at CREA explain that the main driver is the creation of âclean energy basesâ: large-scale concentrations of wind and solar power on deserts … [Read more...]
Record Renewables additions for 2021 and 2022 despite supply bottlenecks prove Solar & Windâs resilience
Despite â or perhaps because of â global market and political turmoil, renewable power is set to break another record in 2022. Thatâs after 2021 also saw record new capacity from solar, wind and other renewables worldwide. Itâs mainly driven by solar PV in China and Europe as governments around the world take advantage of renewablesâ energy security and climate benefits, according to the IEAâs latest Renewable Energy Market Update. 295GW of new … [Read more...]
Chinaâs impressive growth in Renewables and Transmission now needs Market innovation
***REGISTER NOW for CHINA: Carbon Neutral by 2060 - INNOVATION*** - China has the worldâs largest power plant fleet for both coal and renewables. Together they make up most of the total power capacity of over 2,200 GW... STOP PRESS: China's Transition is the biggest single opportunity for managing climate change and also for those businesses who are ready with the innovations that will ensure the best possible outomes in an incredibly … [Read more...]
Solar + Storage Hybrid plants are poised for explosive growth in the U.S.
At the beginning of 2021 the U.S. had 73 solar and 16 wind hybrid projects, amounting to 2.5GW of generation and 0.45GW of storage. By the end of 2021, over a third of the 675GW of solar in the grid connection queue were hybrids, and 19GW were wind hybrids. Only one in four typically get approved, built and connected. But that still points at a twenty-five-fold increase in hybrid generation. Itâs why Joachim Seel, Ben Paulos and Will Gorman at … [Read more...]
Pathway for 100% Renewables in 24 U.S. states by 2035
We should not be surprised to see a growing number of 100% renewables roadmaps, with target dates in the 2030s, from nations as the transition gains pace. This study, âOn the Road to 100 Percent Renewablesâ led by The Union of Concerned Scientists (UCS), details how the 24 states that make up the members of the U.S. Climate Alliance (USCA) can meet all of their electricity needs with renewable energy by 2035. Paula Garcia at UCS summarises the … [Read more...]
Europe must simultaneously replace Russiaâs fossil exports and accelerate its clean energy deployment
The Ukraine crisis has had an immediate impact on Europeâs strategy for energy supply security. And this weekâs sudden halting of gas supplies by Russia to Poland and Bulgaria only emphasises the urgency. Dolf Gielen, Ricardo Gorini, Luis Janeiro and SeĂĄn Collins at IRENA look at the best options, basing their findings on their latest âWorld Energy Transitions Outlookâ, published in March, that lays out a routemap for the next eight years for … [Read more...]
Post-war Ukraine needs energy independence, decarbonisation and EU cooperation
Energy independence is a choice for some countries. For Ukraine it is a life-or-death necessity, says Andriy Konechenkov, VP of the World Wind Energy Association and Chairman of the Ukrainian Wind Energy Association, in this op-ed. The Russian invasion has exposed the vulnerability of Ukraineâs current energy system. Many of its fossil-fuelled power plants are near the Russian border, exposing them to disruption by the invading neighbour. The … [Read more...]
