In EU households, 62.8% of energy consumption is for space heating, and another 15.1% for water heating, mostly powered by fossil fuels. Heating and cooling is responsible for 52% of final energy demand in Europe. So, with REPowerEU, the EU has once again strengthened support for heat pumps to achieve energy independence and climate goals. Heat pump sales in Europe grew by an unprecedented 34% in 2021, thanks to a total 2.18m heat pump units … [Read more...]
30+ nations now subsidise Heat Pumps because lifetime cost is cheaper than fossil boilers
The global growth in heat pumps can deliver almost 40% of all possible emissions cuts from heating by 2030 (with most of the rest coming from efficiency, mainly insulation), says the IEA. This is according to their “Announced Pledges Scenario” (APS) which assumes that governments carry out all of the climate commitments they have made. Keeping buildings warm produces one-tenth of global energy-related CO2 emissions. So the APS’s heat pump growth … [Read more...]
Turning waste biomass into clean fuel: cheap, portable equipment, cuts emissions, earns income for rural poor
The burning of biomass accounts for 10% of primary energy used worldwide: wood, peat, animal dung, corn stalks, rice husks, hay, straw, and other agricultural waste. Billions of people, mainly in remote and poorer regions, rely on such fuels for cooking, heating, and other household needs. But it’s a major source of emissions as well as pollution. And, annually, an estimated $120bn worth of crop and forest residues are burned out in the open … [Read more...]
Cutting energy usage with Behaviour Change: Covid and Russia’s war show it can happen fast
Technology alone won’t meet our net zero targets. For the foreseeable future there will always be carbon-intensive assets and hard-to-abate sectors. Only “behaviour change” by citizens worldwide can bridge the gap that technology cannot. And the reduced energy use that it delivers will also lower the targets that the rapid growth of clean energy supply are now chasing. Here the IEA lays out the challenges in its Behavioural Changes tracking … [Read more...]
If Russia cuts off its gas supply can we achieve EU storage targets for winter?
Calvin Triems at Energy Brainpool summarises their analysis of whether and how Europe can achieve its storage targets for 2022. There are four scenarios: “Base Case”; “[email protected]%” where there’s no change to Russia’s mid-June gas flow cut to 40%; “[email protected]% + No Freeport” where the unexpected fire in early June at the U.S. Freeport LNG terminal remains unresolved for months; “[email protected]% + No Freeport” where Russia cuts off supply … [Read more...]
Implementing Poland’s national Recovery and Resilience Plan
How should Poland implement its national Recovery and Resilience Plan (RRP)? Sonia Buchholtz at Forum Energii outlines some important answers. First, a deep analysis of the challenges and assessment of the solutions and reforms must start now. Buchholtz says though the directions set out in the RRP are correct, the details are out-of-date. Policy reforms and more ambitious targets are needed in all the main areas: energy efficiency and heating; … [Read more...]
Russia-Ukraine: modelling the consequences for the European electricity market to 2050
Alex Schmitt, Christoph Kellermann, Calvin Triems and Huangluolun Zhou at Energy Brainpool have used their modelling tools to update their predictions of how the European electricity market will develop over the next 30 years, given a target of 99% emission-free generation in 2050. Projections are made on generation (mix and volumes) and price. The big change from their last predictions is the Russia-Ukraine war and Europe’s determination to ramp … [Read more...]
EU Heat Pumps: warnings against “one size fits all” policies
The EU is aiming for the installation of 50 million heat pumps by 2030, equating to annual growth of 16%, reaching one third of the total 150 million boiler installations in the bloc. Helen Farrell reviews these ambitious targets and the policies that are driving them, and turns to a report by RAP to identify the weaknesses in the plan and how it can be improved. The main danger is a ‘one size fits all’ approach. Different countries have … [Read more...]
Netherlands and China co-operate on Aquifer Thermal Energy Storage for heating and cooling
Aquifer Thermal Energy Storage (ATES) accesses the stable temperature of groundwater to warm buildings in winter and cool them in summer. The solution uses much less power than conventional heating and cooling systems. As Daisy Chi at ECECP explains, ATES first took off in China in the 1960s but ran into problems with the required circulation of the groundwater. However, the technology has been developed and optimised in the Netherlands: of the … [Read more...]
Why sustainable Buildings are critical for a resilient, healthier society
Europe and its Member States are committing large sums to buildings renovations. The policy emphasis has been on insulation, energy savings and emissions reduction. The latest Healthy Homes Barometer 2022 by Velux draws attention to the health benefits of renovations that target damp, lack of daylight, excess noise or cold, and other indoor climate hazards. To get an idea of the scale of the problem, 34 million Europeans are unable to keep their … [Read more...]
What can replace Russian gas: modelling Germany’s options on renewables, coal, nuclear, LNG, lowering thermostats
A sudden cut in Russian gas imports means Germany will have to cope with the loss of TWhs. How? Tobias Federico at Energy Brainpool wants decision-makers to get the facts straight. He uses modelling tools to answer this question that is causing fierce debate. The first thing to note is that the loss of gas TWhs (of the order of 100TWh) will be most felt in the provision of heat over winter. Heating systems mostly depends on gas, so intermittent … [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...]
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...]
District Heating Roundtable: Policy across RED, EED and EPBD “must take account of conditions in all Member States”
Sara Stefanini provides a written summary of our panel discussion held on 10th February: District Heating under the "Fit for 55" package: challenges and opportunities. Under the “Fit for 55” package, the EC proposed several regulatory changes that, combined, are meant to decarbonise district heating in Europe. But are these options workable for all? The participants raise questions over the support for district heating, whether the multiple … [Read more...]
