In the OECD, since 2000, electricity sector emissions have fallen by 8% while transport emissions have actually increased by 5%. The best performers like the UK recorded drops in both: 40% and 6% respectively. In the U.S. it’s 25% and 0%. Catherine Wolfram at the Haas School of Business asks why transport is still going in the wrong direction, given the power sector’s progress. She posits three theories. Rich nations are outsourcing … [Read more...]
Quantum Well solar cell sets new record for converting light to energy
There’s a new world-record for two-junction solar cells, converting 32.9% of sunlight into electricity. Although it’s only a small improvement on the previous record of 32.8% it uses a design that should lead to even greater performance. NREL, in collaboration with the University of New South Wales (Australia), has built a cell consisting of a series of more than 150 ultrathin layers of alternating semiconductors that create quantum wells which … [Read more...]
The Energy Charter Treaty makes the transition easier. Don’t scrap it, reform it
Energy and climate experts as well as national and EU parliamentarians are lining up to press their governments to withdraw from the Energy Charter Treaty (ECT) if insufficient progress is made in its modernisation. Their main argument is that it gives protection to fossil investments in a world where policies are changing in order to constrain or phase them out. Here, Frank Umbach at EUCERS sternly warns against abandoning the ECT. The treaty … [Read more...]
World’s biggest Steel manufacturers are committing to Hydrogen and CCS
The world’s leading steel makers have announced pledges to reduce emissions, aiming for net-zero by 2050 or sooner. They are committing to various new technologies still not proven at scale: making steel with hydrogen, and some with strategies that include carbon capture. They are putting their money where their mouth is. The list is impressive and includes ArcelorMittal (the world #1), ThyssenKrupp, Voestalpine, SSAB/LKAB/Vattenfall, Nippon … [Read more...]
New net-zero pledges from China, US, EU and others can meet our climate goals, says UNEP. But…
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...]
Coastal town Grande-Synthe took France to court over missed climate targets. How, why and what happens next
Taking your own government to court is an indispensable tool for sticking to our climate goals, says Lucien Chabason at the IDDRI. In November, the French State Council (Conseil d'État) gave an interim judgment largely favourable to the municipality/commune of Grande-Synthe following the government's implicit refusal to take additional measures to comply with the Paris Climate Agreement. Grande-Synthe sits on the coast by Dunkirk and is at … [Read more...]
Nuclear-Wind hybrid plants for grid stability, Power-to-X and more
How would you use a nuclear-wind hybrid plant and maximise its potential? When intermittent wind’s output falls, nuclear can step in to feed the grid. When it’s not doing that it can use its power to run the production of a wide range of commodities: from biofuels, hydrogen, pumped hydro to wastewater purification, desalination, chemical manufacturing and more – including straightforward thermal power for industry. In collaboration with NREL, the … [Read more...]
Nine advantages small-scale solutions have for reducing global emissions
Which is best? Spending your budget on a million 1 KW solar panels or a single 1 GW nuclear/hydro/gas plant? Lots of electric bikes or a single tram system? Lots of smart thermostats or whole-building retrofits? Charlie Wilson (University of East Anglia), Caroline Zimm (IIASA) and Simon De Stercke (Imperial College London) summarise their study that lists the advantages of small-scale “granular” solutions over large-scale “lumpy” ones. Granular … [Read more...]
The top Clean Energy developments of 2020
The world is still a long way off the pathway to meeting our emissions goals. But 2020 saw a number of major steps in the right direction. Laurie Stone at RMI presents a list of what has been achieved and which trends and new policy commitments are pointing us towards a much needed faster transition. They include coal’s decline, wind and solar’s growing competitiveness (even compared to gas), the promise of green hydrogen, bans on gas/petrol … [Read more...]
Bioenergy is the undervalued pillar of the clean energy transition
Bioenergy is already the world’s largest source of renewable energy, responsible for 70% of the supply (and around 10% of total primary energy). Burning organic matter goes back to the invention of fire and is still commonplace around the globe. Yet it gets hardly any of the attention and policy support that’s given to other clean energy technologies like solar, wind and now hydrogen. Bioenergy can and should play an even greater role, explain … [Read more...]
Re-designing the EU ETS to ensure a Just Transition [VIDEO]
On November 30th, 2020, we ran a live online panel discussion concerning the re-design of the EU ETS in the wake of new, higher CO2 reduction targets being agreed by the EU. The target now stands at a 55% reduction c/w 1990 levels by 2030, up from 40%. A huge jump in order to keep in line with Paris commitments. The session was moderated by Matthew James, Managing Director at Energy Post and featured interventions from Andrei Marcu (Chairman at … [Read more...]
HYBRIT project: Sweden goes for zero-carbon steel
Europe’s largest iron ore producer, LKAB of Sweden, plans to invest almost €40bn over the next two decades in emissions-free steel production. LKAB, along with Vattenfall and SSAB, are behind the HYBRIT project which intends to grow, fossil-free, Sweden’s steel industry. They will use hydrogen instead of coal as the “reducing agent” to remove the oxygen from the iron ore. Thomas Koch Blank at RMI runs through their strategy and the implications … [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...]
Coal regions are ideally suited for utility-scale Wind, Solar and jobs
Over 15% of total greenhouse gas emissions in the EU come from coal-fired energy generation. 18 EU countries still use coal for electricity production. The argument goes that the phasing out of coal threatens the livelihoods of coal workers and their regional economy. But it should be the opposite, argue Elif GĂĽndĂĽzyeli and Jörg MĂĽhlenhoff at CAN Europe. Coal regions are ideally suited for new gigawatt-scale wind and solar. They already have the … [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...]
