Sara Stefanini provides a written summary of our panel discussion held on Thursday March 17th 2022. It’s a full summary of the 90 minute discussion (including audience questions), but it begins conveniently with a summary of the highlights (potential for bioenergy, hard-to-abate sectors, sustainability, policy needs). Those highlights include the need to scale bioenergy up from around 50 EJ today to 150 EJ by 2050; the importance of carbon … [Read more...]
Energy Charter Treaty: four ways to amend it and enable green investments
The European Green Deal (EGD) aims to mobilise at least €1 trillion in sustainable investments over the next decade. But the Energy Charter Treaty (ECT) in its current form - designed to protect cross-border investments, enabling those whose energy projects have been shut down to sue nations – is causing fierce debate. The ECT protects all investment alike, but the result has been fossil (and nuclear) investors suing nations that have curtailed … [Read more...]
What is Energy Security? And what it isn’t
What is energy security? That’s what Maximilian Auffhammer at the Energy Institute at Haas asks and tries to answer, and he starts by saying what it is not and what solutions should not be used. Not importing won’t help because prices are global. “Energy security” can’t be taxed as an externality for much the same reason. Subsidising high prices for consumers decreases the value of energy efficiency investments. Instead, Auffhammer says the … [Read more...]
Factory-built energy-efficient modular affordable Housing for reducing lifecycle emissions
Building construction and operation accounts for 37% of global energy-related carbon emissions, according to the UNEP. And every part of the world needs new housing. The U.S. has a 3.8-million-unit housing shortage. Jeffrey Wolf, writing for NREL, describes how modular factory-made affordable net-zero housing is being developed that costs no more than existing construction methods. To get the greatest decarbonisation impact most cost-effectively, … [Read more...]
Russia-Ukraine crisis: reforming the EU ETS is a matter of energy security, says PGE
European leaders are now rushing to make decisions on how to drastically cut dependence on Russian fossil energy imports. Russia’s invasion of Ukraine has exposed Europe’s energy security vulnerabilities like nothing else could have. It also means Europe’s clean energy transition will need an overhaul, and a newly designed optimal pathway created, and fast. Wojciech DÄ…browski, President at PGE Polska Grupa Energetyczna, explains that it must also … [Read more...]
Biomethane for decarbonising transport: the Swedish example
Biomethane has a critical role to play in the decarbonisation of transport, particularly long-distance trucks and ships, where electrification is more difficult and expensive. Angela Sainz Arnau at the European Biogas Association explains that biomethane represents one of the lowest greenhouse gas intensive pathways when the whole emissions lifecycle is measured. However, when nations implement bans on internal combustion engines to cut the use … [Read more...]
Community Biomass: for energy independence, stable prices and local control
Energy independence is now at the top of the EU’s agenda. Almost all Europe’s biomass is already locally produced, contributing around 60% of the EU’s renewable energy. Marine Perrio at IEECP makes the case for promoting biomass prosumer projects. She points at regions dependent on biomass that have reported stable energy prices in the midst of the drastic increases in gas, oil and coal prices. Biomass uses organic feedstock from agriculture, … [Read more...]
Biomass for industrial heat
On Thursday 17th March at 12.30CET our latest Energy Post panel, “Unlocking the potential of bioenergy” boasts representatives from two of the most challenging areas for decarbonisation: the cement and aviation industries. Taking part are  Winston Beck, Head of Government Affairs at HeidelbergCement and Laurent Donceel, Senior Policy Director at Airlines for Europe. They will be joined by Thomas Meth, Chief Commercial Officer at Enviva (event … [Read more...]
Smart households in a high Renewables world: flexible, efficient, cheaper
Smart controls can enable household heating and EVs to interact flexibly with increasingly decentralised electricity generation. As renewables continue to be added to the energy mix, it will increase efficiency, reduce load, and save money. Marco Reiser and Karoline Steinbacher at Guidehouse summarise the challenges and opportunities, before looking at the SINTEG pilot in Germany. The main hurdles are technological (standardisation, interfaces, … [Read more...]
Using atomic-scale imaging and AI to reduce Battery degradation
Finding ways to extend a battery’s life starts with understanding why they degrade. Andrew Myers writing for Stanford University describes research there that is using new methods of high-resolution X-ray, electron and neutron microscopy to allow direct visualisation of battery materials at the nanoscale. Degradation is mostly caused by the expansion and contraction of the materials. The high resolution images are processed using AI to uncover … [Read more...]
Reducing Europe’s dependence on Russian Oil and Gas: immediate, short and long term strategy
Atlantic Council Global Energy Center experts and associates offer their template for drastically reducing Europe’s dependence on Russian oil and gas. It’s broken down into immediate, short (one to three years) and long term (beyond three years) actions. It’s wide-ranging and comprehensive. Some actions are already in play, including maximising gas storage, ready for next winter. Some are the ramping up of existing plans (clean energy, … [Read more...]
IPCC Report on Adaptation: a rapidly closing policy window for climate change action
We do not know how successful we will be at cutting emissions. So “adaptation” is how we change our behaviour, economies, infrastructure and planning to cope with the consequences of climate change. The IPCC’s 6th and latest report looks at the scientific evidence of climate risk and the adaptation solutions being pursued around the world. Alexandre Magnan at IDDRI summarises the findings. It says that by 2100 climate risk will increase two- to … [Read more...]
Germany’s electrification ambitions: TSOs scenario for 91% Renewables by 2045
The German TSOs submitted in January scenarios for their grid to 2037, making projections for increasing electrification. In addition, and for the first time, they included an ambitious and long term scenario to 2045. By pure chance, the Russian invasion of Ukraine and Germany’s response – to consider a reduction in its serious dependence on Russian energy imports – should make eyes turn sharply towards that 2045 scenario. Simon Göss at cr.hub, … [Read more...]
If Buildings Renovation fails, the EU ETS pricing mechanism must change
If the EU “Renovation Wave” for buildings fails, the massive ramp up of clean electrification required to compensate will come into direct conflict with EU ETS pricing formulas, say Sebastian Osorio and Michael Pahle at the Potsdam Institute for Climate Impact Research and Oliver Ruhnau at the Hertie School in Berlin. If the cap in the original ETS is too tight relative to the Effort Sharing Regulation (ESR) targets, its carbon prices may rise … [Read more...]
Getting Concentrated Solar Power (CSP) down to $0.05 per kWh
The U.S. Department of Energy is funding research to get the cost of Concentrated Solar Power (CSP) down to $0.05 per kWh. One key element of that research is the materials used to absorb and store the heat energy. Three categories of materials are being looked at: liquid (i.e. molten salt), particle (like sand), and gaseous. NREL is leading the molten salt research, and there are multiple challenges. The salts can corrode the storage tanks and … [Read more...]
