Existing national commitments imply that today’s emissions will simply plateau, remaining only slightly below 2019 levels by 2030. However, according to the latest UN Environment Programme (UNEP) emissions gap report, the new commitments from China, the EU, Japan, South Korea, the UK, Joe Biden’s US and others are “broadly consistent” with the Paris Agreement’s 1.5C goal for 2050. But commitments aren’t policy, warns UNEP, and only real change … [Read more...]
A beginner’s guide to European climate laws
Confused by the range of EU and national climate laws? The EU-ETS, the Effort-Sharing Regulation, the Renewable Energy Directive, the Energy Efficiency Directive, the Clean Energy for all Europeans Package, LULUCF, and more? Which are the important ones? Who exactly is making policy, and how? What are the real world effects? Julian Wettengel at Clean Energy Wire has asked experts to improve our understanding by answering a list of questions on … [Read more...]
Satellite monitoring of Methane leaks makes policing them more effective
Satellites, drones, and airplanes should be used to detect methane leaks across the million active wells and hundreds of thousands of miles of pipelines across the U.S. That’s because without proper monitoring it’s extremely hard to find leaks, let alone regulate them. Meredith Fowlie at UC Berkeley’s Energy Institute at Haas describes their paper that uses such data to, first, show that 2.3% of upstream natural gas production is leaking. That’s … [Read more...]
What effect will blending Hydrogen into the Natural Gas network have?
What are the technical barriers to blending hydrogen into the natural gas network? How well will the pipelines cope? How will the blend affect equipment and appliances? What are the costs and environmental impacts? The answers to these key questions are being sought by a collaboration of laboratories, industry and academia led by NREL, called HyBlend. The long-term impact of hydrogen on materials and equipment is still not understood. The effect … [Read more...]
Biofuels vs Hydrogen: which can fuel aviation, shipping, trucks?
The positive signals coming from EV sales and charge points contrast with the lack of progress in finding alternative fuels for aviation, shipping and trucks. Cornelius Claeys runs through the prospects for biofuels and hydrogen to power long-haul transport. Biofuels are already used as a substitute for fossil fuels, and EV uptake will usefully free them for fuelling heavy transport. But as decarbonisation ambitions rise the pressure on scarce … [Read more...]
Create new laws to help bring Battery manufacturing to Europe
Europe should start leading battery manufacturing instead of leaving it to China, argue Alex Keynes and Cecilia Mattea at Transport & Environment. With laws spreading across the continent to make electric vehicles compulsory for new car purchases, this is a growing and strategic market. But a firm grip on battery manufacture emissions, as well as ethical sourcing and recycling, has to be part of the plan. The authors give a template of what … [Read more...]
Green or Blue Hydrogen: cost analysis uncovers which is best for the Hydrogen Economy
Blue hydrogen is created from fossil sources, where the carbon emissions are captured and stored. Green hydrogen is made from non-fossil sources and favoured by policy makers who are wary of keeping the fossil economy going, even with CCS. As more regions commit to hydrogen, finding the right cost-optimal mix is crucial to its success. Schalk Cloete summarises his paper that models the whole system based on Germany. Integrating hydrogen will … [Read more...]
Chinese energy institutes present new net-zero scenarios for 2050
It was just one sentence, in September, from China’s President Xi Jinping: “We aim to have CO2 emissions peak before 2030 and achieve carbon neutrality before 2060.” Already, leading Chinese energy institutes have presented two scenarios that lay out what needs to be done to meet that goal. Writing for Carbon Brief, Lauri Myllyvirta reviews the plans. Both aim for over 85% of all energy and more than 90% of electricity coming from non-fossil … [Read more...]
The IEA’s World Energy Outlook 2020 at a glance
This month the IEA published its annual flagship World Energy Outlook (WEO). Simon Göss at Energy Brainpool picks out his highlights. This year’s WEO has four scenarios, two of them new: an updated “Stated Policies Scenario” (STEPS: what governments have promised), the new “Delayed Recovery Scenario” (DRS: due to Covid), an updated “Sustainable Development Scenario” (SDS: what’s needed to meet the Paris targets), and the new “Net Zero Emissions … [Read more...]
World Energy Outlook 2020: IEA responds to some difficult questions
The IEA has issued an FAQ to try to answer some persistent questions and criticisms about their annual World Energy Outlooks (WEO). How come the growth of solar and wind have been consistently underestimated? When is “peak oil” going to happen? Will the IEA’s Sustainable Development Scenario limit the global temperature rise to 1.5 °C this century? Is it realistic? Why has a “Net Zero Emissions by 2050” (NZE2050) pathway been added this year? Do … [Read more...]
China’s new net zero emissions target for 2060: why now, and how?
China’s promise of peak emissions before 2030 and net zero by 2060 is a major and welcome step for the economic (and fossil fuel) powerhouse. Better still, the rest of the world doesn’t need to make concessions to get China to stick to the new target, says John Seaman at the IFRI Centre for Energy & Climate. That’s because an energy transition is in China’s interests. It wants and needs to be at the forefront of new energy technologies to … [Read more...]
Changes to national targets and forestry mean EC’s 55% plan is weaker than it looks
The EC’s plan to reduce the bloc’s emissions by 55% by 2030 compared to 1990 levels, instead of the previously agreed 40%, is very welcome but its implementation plan is flawed, says William Todts at Transport & Environment. The EU Emissions Trading System (EU ETS) won’t be enough on its own. So the plan allows nations to include “managing” forests and “tree plantations”, a big change because forests were not part of previous emissions … [Read more...]
Europe’s 55% emissions cut by 2030: proposed target means even faster coal exit
The EC is proposing a target emissions reduction of 55% by 2030 compared to 1990 levels, instead of the previously agreed 40% (which the EU is on course to surpass). The main tool for achieving it will be the EU Emissions Trading System (ETS). Prices for allowances will rise, making coal increasingly uncompetitive. Sören Amelang, Kerstine Appunn and Julian Wettengel at CLEW talked to a number of experts who say the new target implies a near total … [Read more...]
Tesla’s BEVs vs. Toyota’s hybrids: the battle for the future of low emission cars
Which car firm will dominate the future? Tesla and its BEVs or Toyota with its hybrids? Schalk Cloete looks at the cost reductions coming down the line. He says that the hybrids have many more improvements on the way, whereas in terms of performance and efficiency the BEVs are already reaching their peak. Though further and considerable progress in battery technology is coming, it will benefit both. For city driving both will rely on battery … [Read more...]
Net Zero by 2050 technically and economically achievable, says Energy Transitions Commission report
Making Mission Possible, the latest report by the Energy Transitions Commission, describes a net-zero world by mid-century as technically and economically possible. The solutions are already available or close to being brought to market. What is still missing is the will to embrace, rapidly and at scale, the inevitable disruption that will ultimately deliver net-zero emissions, lower air pollution, cheaper energy bills, create new jobs and raise … [Read more...]
