Energy-intensive industries that invest in their own large on-site batteries will provide multiple benefits to themselves as well as to grid stability, says a new study by the Joint Institute for Strategic Energy (JISEA) in partnership with NREL and others. It matters because future power systems will need to be highly flexible due to the variability of wind and solar. The study assessed two established energy-intensive industries (chlor-alkali … [Read more...]
Will Wind & Solar confront its 10 challenges? If not, we need Nuclear, CCS, and more
Wind and solar’s impressive cost declines have seen its welcome and rapid emergence. But currently they account for a mere 2–4% of global energy. So these variable renewable energy sources (VREs) must now address 10 big challenges if they are to dominate the energy sector, explains Schalk Cloete in this data-led review. Their cost declines will be confronted and even cancelled by new costs they’ve not yet faced during their low-hanging-fruit … [Read more...]
How much Carbon Capture will Germany need? Both nature-based and technological
Yet more studies have been published that show Germany needs carbon removal to meet its emissions targets. Simon Göss and Hendrik Schuldt at cr.hub add two, from the German Energy Agency and the Ariadne report (funded by the German Ministry of Education and Research), to those that already exist to shine more light on a carbon capture pathway. The main observation is that nature-based solutions (LULUCF: land use, land use change and forestry) … [Read more...]
Modelling Hydrogen’s role in high penetration Wind + Solar grids
A hydrogen ramp-up is going to be expensive and asset-heavy. So, a whole-system analysis is needed to ensure its deployment is done cost-effectively today and meets long term goals. This is what all nations committing to hydrogen are struggling with. Kelley Travers at MIT describes their modelling, in collaboration with Shell, that looks at the optimisation of hydrogen deployment in grids where variable renewables (VREs) like wind and solar are … [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...]
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...]
‘Fit for 55’ should prioritise decarbonisation of laggards: buildings, transport, industry, agriculture
Today’s 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...]
UK: exposing the gap between ambitious climate laws and actual policies
Like many nations, the UK has big gaps between what is actually needed to reach net zero by 2050, what targets and ambitions have actually passed into law, and what policies are actually in place to comply with those laws. The UK’s climate watchdog, the Climate Change Committee (CCC), has issued two reports that measure the UK’s performance and makes recommendations, summarised here by Josh Gabbatiss at Carbon Brief. The first report focuses on … [Read more...]
Cement: replacing limestone with volcanic rock could slash energy use, and emissions by two-thirds
Cement production accounts for 8% of global emissions, and it will rise as nations get richer and build more. It’s mainly because of the energy needed for the high heat process, and the carbon released from the limestone used. It’s one of the leading hard-to-abate sectors, and coming up with an alternative process and cement recipe is firmly on the industry’s agenda. Josie Garthwaite at Stanford University summarises a study that aims to replace … [Read more...]
EU’s Carbon Border Adjustment Mechanism lacks the detail to drive industry’s relocation near clean energy
High emissions industries should be relocated to where the cheap clean energy is. So long as the shipping costs (in terms of price and emissions) aren’t prohibitively high, those locations can be anywhere in the world. To get the calculations right, Carbon Border Adjustment Mechanisms (accounting for the emissions of imported goods) must be harmonised internationally. They must also – crucially – count all relevant emissions. But the EU’s draft … [Read more...]
The EU’s “Fit for 55” package: a primer on the EU ETS and other main policy levers
On July 14 the European Commission will present the much awaited “Fit for 55” legislative package. Lara Dombrowski and Simon Göss at Energy Brainpool have written a very useful primer on what’s at stake for the EU ETS, along with a summary of the other main policy levers that will be decided upon. The authors describe the EU ETS as the central instrument for reducing greenhouse gas emissions. It caps emissions for 10,000 power sector, industrial … [Read more...]
Does new German target mean Coal gone by 2029, Renewables 65% by 2030?
The stiffer emissions targets introduced this month to Germany’s Climate Protection Law - CO2 emissions from the energy industry must fall to 108 Mt by 2030 instead of 175 – 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 Claußner, Carlos Perez-Linkenheil and Simon Göss at Energy Brainpool explain why, using their modelling … [Read more...]
Where to start building Hydrogen pipelines? Near industrial hubs for steel, ammonia, and plastics
Converting gas pipelines to carry hydrogen is going to be expensive. We don’t even know how much hydrogen we’ll really need in 2050, given electrification – the cheaper and preferred option to replace fossil fuels – will always be the first option. But we do know that certain industries like steel, ammonia, and plastics will always need hydrogen as a feedstock. Writing for WEF, Kevin Tu, Matthias Deutsch and Gniewomir Flis at Agora Energiewende … [Read more...]
