There is concern that eradicating poverty in the global south means their growing wealth and energy consumption will make our climate targets too hard to meet. Here, Jarmo Kikstra and Narasimha Rao, writing for Carbon Brief, explain that the energy needed to eradicate poverty is compatible with climate goals, provided that policymakers focus on delivering decent living standards, and not copying the affluence and habits of rich countries. Most … [Read more...]
Giving car manufacturers e-fuel credits will slow the rise of EVs
Transport & Environment (T&E) explains why e-fuel credits should not be included in the EU’s CO2 standards for new cars. If they are, it would give carmakers the option to claim an ICE vehicle as low- or zero-emission. But carmakers have no control over what fuel their customers put in their cars, making the regulation impossible to monitor. That opens the door to double-counting emission reductions with other existing regulations (Fuel … [Read more...]
Can Aluminium-air batteries outperform Li-ion for EVs?
Aluminium-air (Al-air) batteries for cars are an innovative technology that automakers and policy-makers should take a close look at, say Helena Uhde and Veronika Spurná at ECECP. Although a battery, they behave more like an engine: the fuel is the aluminium which reacts with the air via an electrolyte to produce electric power. Al-air has big advantages over a lithium-ion battery, the favoured choice for EVs. It has a travel range similar to … [Read more...]
Decommissioning coal, oil, gas: how funds can buy and retire the assets
Companies that want to retire their CO2-emitting assets (coal, oil, gas) can struggle to afford the cost of the decommissioning process. Brad Handler and Morgan Bazilian at the Payne Institute for Public Policy, writing for the World Economic Forum, explain how the creation of a new financial instrument, the 'carbon retirement portfolio' (CRP), could be a solution. In essence, it’s simple. Investors create a fund that buys the asset and takes the … [Read more...]
Only Carbon Removal can make Germany’s new climate goal a reality
Germany can’t hit its emissions targets without significant carbon dioxide removal (CRD), explain Simon Göss and Hendrik Schuldt at cr.hub. Clean energy and energy efficiency won’t do it alone. Policymakers have grasped that hard-to-abate sectors (industry, agriculture, buildings, transport) will struggle to deliver the reductions needed. Meanwhile, the climate disasters (floods, wildfires, etc.) that have cost lives this year are piling on … [Read more...]
Renewable Hydrogen: what policy instruments are needed to reach the new targets?
A comprehensive mix of policy instruments is needed to ensure that the EU meets its ambitious hydrogen targets. What should they look like? Pia Kerres, Matthias Schimmel and Corinna Klessmann at Guidehouse quote their study, done in collaboration with Agora Energiewende, for the answers. Industry and long-haul transport should be the main customers for hydrogen. The big challenge is to cut the cost of hydrogen production; it’s too expensive and … [Read more...]
Is China really eyeing Afghanistan’s mineral resources?
Press reports of China hoping to strike deals with the Taliban to secure mineral rights in Afghanistan are very likely to be an exaggeration, explains Lukas Trakimavičius. It’s true that China wants minerals essential to the clean energy transition and other technologies. It’s also true that Afghanistan has an abundance (copper, cobalt, lithium, rare earths, etc.), and they’re worth something of the order of $1tn. But it can take a decade to get … [Read more...]
Electric Micromobility: how to cut emissions, create jobs and transform urban transport
What if e-bikes, electric scooters and electric skateboards were added to walking and cycling in our attempts to reduce emissions through behaviour change? It’s a promising solution for all those people who genuinely want to reduce their emissions but don’t want the extra exercise. Quoting from their report, Jennifer Dungs at EIT InnoEnergy looks at the gains to be made, along with a valuable reduction in city congestion. Micromobility is still … [Read more...]
CBAM needs universal adoption of methods for measuring carbon intensity
Europe needs to account for the emissions of imported goods. That cannot happen without the international agreement on standards and certification systems for the carbon intensity of all steps in the value chain for all relevant products. Dolf Gielen and Francisco Boshell at IRENA and Massamba Thioye at the UNFCCC explain that several such systems exist around the world, but they need to be harmonised and widely adopted to truly reflect what is … [Read more...]
EU “Fit for 55”: how it impacts the EU ETS to accelerate emissions reductions
Christoph Kellermann, Lun Zhou and Simon Göss at Energy Brainpool explain how the EU’s new “Fit for 55” proposals, released in July, will impact the EU Emissions Trading Scheme (EU ETS), hailed as one of the most effective ways of reducing emissions. The authors cover the changes to the existing ETS, the planned new ETS for road transport and buildings, the controversial Carbon Border Adjustment Mechanism (CBAM), and the new CO2 standards for … [Read more...]
Summer break! See you in September
As always, Energy Post thanks all of our readers and expert contributors for another great first half of the year. We are running important online panel events every month (3 in February made that month particularly busy) and are planning many more, so do get in touch if you have suggestions, can bring expert knowledge to our panels, or are interested in sponsoring. Our readers continue to share our articles widely on social media, which is … [Read more...]
We’re not costing energy correctly: reward clean energy optimisation, not maximum generation
Laura Sandys at Energy Systems Catapult says policy makers today are too focussed on rewarding clean energy generation, in other words supplying as much energy as possible. With that comes a focus on reducing the cost of the energy generated. But how about reducing demand? Demand optimisation should be equally rewarded: efficiency, non-generation demand management (even at the household level: think EVs and heat pumps), and any assets that … [Read more...]
Record global power sector emissions by 2022, because Renewables aren’t 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 renewables’ 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 IEA’s (and many others’) “Roadmap to Net Zero by 2050” 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?
There’s 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...]
Engineering yeast to create Biofuels from non-food crops (straw, grass, cellulosic waste)
Using ethanol can reduce the global consumption of fossil fuels. But, commercially, ethanol in the U.S. is produced from corn and not enough is grown to make a significant impact on U.S. fuel needs. Anne Trafton at MIT describes research that has engineered yeast to break down straw and woody plant material to create ethanol as efficiently as it’s done from corn. High yields of ethanol were extracted from five different types of cellulosic … [Read more...]
