Gas emissions must be halved (and coal eliminated) by 2030 to meet President Bidenâs goal of a carbon free power sector by 2035. The problem is that gas additions are half the price of new wind and solar installations. Though the clean energy champions are still getting cheaper, so are gas additions. Nikos Tsafos at the Center for Strategic and International Studies looks at the policy options over the next decade for the U.S. The stark fact is … [Read more...]
New thermoplastic blades for coastal Tidal Energy turbines
Large-scale tidal power turbines provide an option for clean energy generation that doesnât depend on the weather, like wind and solar. Research led by NREL is using, for the first time anywhere, thermoplastic composite blades that will improve fatigue performance over typical epoxy blades, can be manufactured faster and more energy efficiently, and can be recycled. The test site is located in New York City's East River, installed in Verdant … [Read more...]
Record global power sector emissions by 2022, because Renewables arenât growing fast enough
The IEA is forecasting that renewables will cover only half the projected increase in global electricity demand in 2021 and 2022. Despite renewablesâ impressive growth, coal and gas will be needed to cover the rest. That means emissions will rise to record levels. That will be the reverse of the IEAâs (and many othersâ) âRoadmap to Net Zero by 2050â pathway, where three-quarters of global emissions reductions between 2020 and 2025 come from the … [Read more...]
Hydrogen production in 2050: how much water will 74EJ need?
Thereâs no point ramping up hydrogen if other resource constraints are going to bring it to a halt. Here, Herib Blanco at IRENA summarises their research into how much water will be needed in the production of hydrogen through electrolysis (i.e. from water) and the costs involved. A wide range of analyses have been reviewed to calculate the amount of water used during the hydrogen production, and by the energy source used to power it (renewables … [Read more...]
Wind, Solar: continuing cost declines will help meet rising renewables targets
The ECâs âFit for 55â proposals include the raising of the EUâs 2030 target for total energy produced from renewable sources to 40%. Much of the rest of the world will likely raise its targets at some point too. Continuing to cut the cost of renewable energy generation will be essential to make that happen, and take pressure off all the other associated costs of supporting its integration into the energy system. Michael Taylor at IRENA summarises … [Read more...]
‘Fit for 55’ should prioritise decarbonisation of laggards: buildings, transport, industry, agriculture
Todayâs long-awaited "Fit for 55" legislative package from the European Commission will trigger intense and difficult negotiations that will last two years, says Nicolas Berghmans at IDDRI. Its scope is wide and inevitably interconnected. The twelve legislative proposals include adjustments to existing measures (renewable energy, energy efficiency, carbon market/EU ETS, energy taxation, climate effort sharing between Member States/ESR, land use … [Read more...]
End Fossil Fuel subsidies by shifting them to poorer households
In May, the environment ministers of the G7 agreed to end fossil fuel subsidies within this decade. Around $650 bn/year is spent worldwide on subsidising all energy sources, with the majority ($450bn) going to fossil fuels despite the climate crisis. But simply removing the subsidies has proven difficult. They keep energy costs low for consumers. Itâs why public protest resisted the change in Ecuador and France in 2019. And developing nations … [Read more...]
What if Carbon Capture fails? Modelling the consequences and solutions
Most policy scenarios being used by governments include carbon capture as a vital tool to reduce emissions. Though itâs far from proven at scale, models assume that between 2030 and 2050 carbon dioxide removal (CDR) will get its act together and deliver on its part in the net-zero puzzle. Assuming that will happen, burning fossil fuels can continue for longer. But Neil Grant and Ajay Gambhir at Imperial College London, writing for Carbon Brief, … [Read more...]
How Clean Energy Standards have driven clean electrification in the U.S.
John Rogers at the Union of Concerned Scientists presents evidence from the U.S. of the effectiveness of using standards to drive clean electrification. In principle itâs simple: set a legal requirement for the percentage of clean electricity. How itâs done depends on the efforts of all the actors affected. 30 states are using different versions of Clean Energy Standards (CES) â the first began in 1983 and more than half of them began before 2004 … [Read more...]
Does new German target mean Coal gone by 2029, Renewables 65% by 2030?
The stiffer emissions targets introduced this month to Germanyâs Climate Protection Law - CO2 emissions from the energy industry must fall to 108 Mt by 2030 instead of 175 â point to an even earlier coal phase-out date of 2029, with renewables generating 65% of electricity by 2030. The existing plan had meant coal must be gone by 2038. Michael ClauĂner, Carlos Perez-Linkenheil and Simon Göss at Energy Brainpool explain why, using their modelling … [Read more...]
18 energy transition scenarios to watch: where they agree and disagree
A wide range of regions, nations and respected organisations have created net-zero strategies and pathways, but on what do they agree and disagree? Dolf Gielen, Asami Miketa, Ricardo Gorini and Pablo Carvajal at IRENA have done a meta-analysis of 18 recent energy transition scenarios to find out. There is consensus over the main strategies: renewable power generation, and the direct and indirect electrification of end-use sectors â these account … [Read more...]
Bidenâs Leaders Summit: turning climate commitments into solutions
President Biden's Leaders Summit on Climate last month helped focus minds on making firm commitments to reducing global emissions. As we all know, targets are one thing, credible and realistic solutions are another. To understand the challenge better, Dolf Gielen, Ricardo Gorini and Gayathri Prakash at IRENA break down into themes those areas that need much more effort and, if dealt with successfully, can get us to net zero by 2050: structural … [Read more...]
China: decoupling GDP growth from rising emissions
To set up this weekâs important online event (Tuesday 13th & Wednesday 14th April) âChina: Carbon Neutral by 2060 -EFFICIENCY FIRSTâ we have an overview of Chinaâs energy transition. Everyone agrees its performance is critical for the world to achieve the global goal of limiting warming to 1.5C by 2050. China made significant progress in 2020 with policy frameworks, renewable capacity additions and EVs, but it also added 38 GW of new … [Read more...]
“The Role of the EU ETS in Decarbonisation to 2030” [written summary of the panel discussion]
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 thereâs clearly a problem. The counter argument is that there are other funding mechanisms available, and more … [Read more...]
