Ten years ago there was a major drive to get carbon capture off the ground. But only 30% of the earmarked $8.5bn worldwide was ever spent. Spending timescales were too short, deadlines were missed, projects were too focussed and too complex, and long-term liability was poorly understood and managed. This time it can be different, says Samantha McCulloch at the IEA who compares that faltering history with the plans now being put in place. New … [Read more...]
Renewed interest in Carbon Capture strategies for net-zero: targets, obstacles, costs, priorities
Martina Lyons at IRENA picks out the highlights of their new report “Reaching Zero with Renewables: Capturing Carbon”. Carbon capture is going to be expensive, so should be focussed on hard-to-abate industrial sectors, as well as bioenergy plants. Lyons breaks down the target carbon capture volumes, costs and the investments required, as well as looking at the consequences of different strategies and carbon prices. Scaling up this technology, … [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...]
Coal phase-out by 21 nations only accounts for 3.2% of global power. What about the others?
The 21 nations committed to coal phase-out only account for 3.2% of global electricity generation. Three - Belgium, Austria and Sweden – have already done so. The rest hope to by different dates, ranging to 2040. Asia is where the main problem is, and their transition challenges are well known: growing economies, and energy security. Carlos Fernández Alvarez at the IEA spells out their recommendations, and references case studies in Canada, the … [Read more...]
Methane Removal: an overlooked climate solution that could cut temperatures by 1°C?
If you think CO2 removal isn’t getting enough attention, methane removal is getting virtually none. There are attempts to reduce methane emissions directly from fossil fuel production. But Rob Jordan at the Stanford Woods Institute for the Environment describes studies and models that conclude we should be looking at large and wide scale reduction and capture of methane. A 40% reduction in global methane emissions by 2050 could reduce peak … [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...]
Comparing four Carbon Removal scenarios (IPCC, IEA, McKinsey, NGFS) and policy implications
Most net-zero scenarios include carbon removal as a major component. Simon Göss and Hendrik Schuldt at cr.hub review five major scenarios from the IPCC, IEA, ETC, McKinsey, and the Network for Greening the Financial System (NGFS). They start by making the very important distinction between carbon capture and negative emissions: capturing carbon from, say, a gas plant does not deliver negative emissions, it just prevents new emissions. This … [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 it’s 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...]
U.S. can’t hit net-zero power target by 2035 without Advanced Nuclear
President Biden’s target of net-zero power generation by 2035 will be extremely challenging, if not impossible, argues Charles Merlin writing for IFRI. He says the best chance of achieving it is through advanced nuclear reactors, though the 2030+ switch-on dates of the new technology still won’t guarantee meeting Biden’s timescales. Why should the U.S. drive for advanced nuclear? Because of the known limitations of the other technologies. Wind … [Read more...]
Europe’s Carbon Capture pipeline: 40+ projects. But where’s the policy support and market creation?
13 different European countries have announced more than 40 carbon capture projects. Most are yet to become operational, but the commitment from the private sector – ranging from new players to established energy and industry majors – is clear. Now is the time for governments to create for CCUS the kind of policies that accelerated the growth of wind and solar, says Lee Beck at the Clean Air Task Force. Norway and the Netherlands are taking those … [Read more...]
NW Europe’s Hydrogen targets: ambition must match reality
The IEA’s report released earlier this year, “Hydrogen in North-Western Europe: A vision towards 2030”, welcomes the fact that the six countries analysed - Belgium, Denmark, France, Germany, the Netherlands, Norway and the UK – have the ambition to build a hydrogen economy. They are Europe’s major hydrogen producers and consumers, have major ports that already service this sector, have natural gas infrastructure that can be repurposed, and access … [Read more...]
Case study Italy: Optimising emissions cuts means we’ll need “grey” and “blue” Hydrogen too
Europe is committing to hydrogen. The ideal is “green” hydrogen, produced from renewable energy alone. Carlo Stagnaro at Istituto Bruno Leoni analyses emissions and costs in Italy to make the case for policy-makers to consider including “grey” and “blue” hydrogen in their strategies too. Because grids are far from green today, a new wind and solar plant will reduce more emissions by feeding the grid than by making hydrogen. “Grey” hydrogen, … [Read more...]
Clean Hydrogen from water electrolysis: research into catalysts to meet global targets
The full potential of the new hydrogen economy will depend on producing enough clean hydrogen from water electrolysis which uses precious metals. But, as Glennda Chui at SLAC (Stanford University & DoE) explains, there aren’t enough precious metals in the world to get to the scale we need. And their cost is so high the clean hydrogen they generate could never compete with hydrogen derived from fossil fuels. Over 95% of hydrogen produced today … [Read more...]
