Coal Phase-Out in Central Europe: cooperation is better than law suits
On Monday (February 22nd 2021) the Czech government announced their intention to file a lawsuit in the EU Court of Justice against Poland’s plan to “expand the mining” at Turow, saying it can endanger the drinking water for up to 30,000 people living in the Liberec Region. Frank Umbach at EUCERS argues such a lawsuit sets a dangerous precedent that could stand in the way of regional cooperation and achieving the EU’s climate goals. Instead, the … [Read more...]
Wave Energy: how variable geometry designs can raise conversion efficiency
Wave energy is another renewable technology waiting to break through. One main challenge is that about 35%–50% of WEC (wave energy converter) costs come from the device structure alone. Researchers at NREL are experimenting with variable geometry, changing the shape of the WEC so that in more energetic seas the structural loads are controlled. In turbulent seas the excess load can easily be shed, while when the seas are quiet the maximum energy … [Read more...]
A people-powered energy system: activating the community energy market for bioenergy
Among others, lack of preparedness for communities to tap the full bioenergy market potential[1], lack of bioenergy stakeholders’ awareness of the potential of communities and missing/ unsupportive (local, regional and national) framework and policy conditions. For a people-powered energy system, the Horizon 2020-funded project BECoop (2020-2023) aims at putting communities in charge of their local renewable (bio)energy generation. … [Read more...]
Germany’s Renewable Energy Act 2021: how to implement the fine policy detail of emissions reduction targets
After much haggling and debate, Germany’s Renewable Energy Act (EEG) 2021 was finally approved in December and came into force on 1 January 2021. Sila Akat and Simon Göss at Energy Brainpool outline the most important changes imposed by the amendment. It gives an insight into how a nation is dealing with the finer details of increasingly ambitious emissions reduction targets. The authors cover the main issues and outcomes. How Germany is dealing … [Read more...]
Wide variations in National Energy and Climate Plans: how can the EU seriously budget for emissions reductions?
The EU has big and growing ambitions for emissions reductions by 2030: down 40% below 1990 levels, increasing the share of renewables to 32% of final energy consumption and improving energy efficiency by 32.5% above business-as-usual. These targets will be further revised as the more ambitious goal of cutting emissions by 55% by 2030 becomes legally binding. This means the EU as well as individual nations must estimate the cost of meeting these … [Read more...]
Carbon Offsetting via old wind and solar farms is no way to reduce emissions
Companies can offset their emissions by buying carbon credits, where the money goes to fund clean energy projects. But the carbon credit market includes credits for very old projects. This is a foolish waste, explain Mark Maslin and Simon Lewis at UCL (UK). The market must be based on the principle of additionality: the money should be aimed at projects that would not have happened otherwise, thereby causing emissions reductions that would not … [Read more...]
Decarbonising Industry is key to China’s net-zero strategy
China has committed to a CO2 emissions peak before 2030 and carbon neutrality before 2060. It’s 14th 5-year plan will be released in March, followed by sector-oriented plans. For the first time it will include a dedicated plan addressing climate change. Dolf Gielen, Yong Chen and Paul Durrant at IRENA start by laying out China’s energy mix for scrutiny, then dive into its industrial sector which accounts for 60% of gross final energy use. Success … [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...]
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...]
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...]
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...]
The renewable electricity market in Ukraine: answers to the key questions
Tetiana Mylenka at Hillmont Partners law firm (Kyiv, London) answers key questions about the prospects for renewable energy in Ukraine. Is there any hope that the renewable energy sector in Ukraine is coming out of its crisis? As of today, it is too early to say that the renewable energy sector in Ukraine is coming out of its crisis. The adoption of the long-awaited Law No. 810-IX should resolve the situation and partially … [Read more...]
IEA’s “accelerated case” becoming the norm? Global Wind + Solar to overtake Gas and Coal by 2024
The IEA’s 2019 “accelerated case” for renewables is turning into this year’s “main case”. It predicts that Wind and Solar capacity combined will overtake both Gas and Coal globally by 2024. Josh Gabbatiss at Carbon Brief summarises the IEA’s Renewables 2020 report. Within five years, renewables will constitute 1/3 of all electricity generation, equivalent to the combined demand of China and the EU. Virtually all global growth in electricity … [Read more...]
