As news across Europe shows, a combination of factors is seeing coal powered electricity generation on the increase. Simon Göss at cr.hub, writing for Energy Brainpool, takes a close look at whatâs going on in Germany. The post-pandemic demand bounce-back, low generation from wind due to calm weather, and record high gas prices have made coal more competitive. Thatâs even with rising prices for CO2 and record high prices for coal (caused by … [Read more...]
Nanochemistry breakthrough could lift energy density of batteries by factor six
Finding new ways for batteries to increase the charge they can store will lift their energy density. Researchers at Stanford University have developed an alkali metal-chlorine battery that stores six times the charge of todayâs commercially available lithium-ion batteries. Until this breakthrough, a high-performance rechargeable sodium-chlorine or lithium-chlorine battery has been impractical because chlorine is too reactive to convert back to an … [Read more...]
Energy-efficient and affordable housing will increase public support for the Green Deal
Energy poverty â the inability to afford basic household energy needs â affects up to one-third of U.S and European households. The energy transition can be part of the solution, says Clare Taylor. Targeted energy-efficient retrofits and newbuilds for low-income households will cut bills and improve living conditions. This will not only cut emissions, but get the beneficiaries behind wider climate change policies like the Green Deals in Europe … [Read more...]
Can full-scale Distributed Solar really save $473bn in grid investments?
A giant model of the entire US electricity sector which captures distributed energy resource (DER) potential has been getting a lot of attention. It estimates that distributed solar and storage can save $473bn in system-wide costs when deployed at scale (enough to power more than 25% of US homes). Rooftop solar is definitely much more expensive than grid generation, but its location (on your own roof) avoids a range of costly transmission and … [Read more...]
Green Finance standards: the EU Taxonomy and Chinaâs âCatalogueâ
The EU Taxonomy was published in June 2020. It is the first official document to define and classify what is a truly sustainable economic activity in Europe. Six months later Chinaâs regulators published their own version, a new edition of the China Green Bond Endorsed Project Catalogue (the Catalogue). Both documents will act as important standards for green finance institutions and investors in Europe and China. They are intended to improve … [Read more...]
Nuclear Fusion: U.S. and China race to build worldâs first commercial plant
Both the U.S. and China are investing in nuclear fusion, and expecting results. Fusionâs unresolved engineering challenges (getting more power out than you have to put in) must be overcome first. If achieved, it offers the prospect of an almost inexhaustible source of energy. As Dan Yurman explains, this month the U.S. passed a bill that includes $2.8bn for fusion energy-related projects and research. The U.S. Fusion Industry Association said … [Read more...]
New thermoplastic blades for coastal Tidal Energy turbines
Large-scale tidal power turbines provide an option for clean energy generation that doesnât depend on the weather, like wind and solar. Research led by NREL is using, for the first time anywhere, thermoplastic composite blades that will improve fatigue performance over typical epoxy blades, can be manufactured faster and more energy efficiently, and can be recycled. The test site is located in New York City's East River, installed in Verdant … [Read more...]
How much Hydrogen will the German Gas Network have?
What will be the scale and design of Germanyâs hydrogen roll-out? Different scenarios are coming to wildly different conclusions. Simon Göss at cr.hub, writing for Energy Brainpool, looks at several, including the dena-TM95 scenario of the German transmission system operators for gas (FNB Gas) where gas consumption rises, and the NECP-KSP 87.5 scenario of the German Ministry for Economic Affairs where gas consumption falls. The possible hydrogen … [Read more...]
How to share the cost of an EU-wide Hydrogen network
The EUâs ambition is to make green hydrogen available throughout the region, and ramp up the transportation infrastructure as fast as possible to deliver it at a competitive price. But there are big disagreements between stakeholders over how and who should pay, explains Walter Boltz. The simplest solutions like focussing on hydrogen clusters will only deliver it to nearby customers. If only the customers pay it will make the hydrogen very … [Read more...]
Eradicate global poverty, meet climate goals, by avoiding rich-world energy consumption patterns
There is concern that eradicating poverty in the global south means their growing wealth and energy consumption will make our climate targets too hard to meet. Here, Jarmo Kikstra and Narasimha Rao, writing for Carbon Brief, explain that the energy needed to eradicate poverty is compatible with climate goals, provided that policymakers focus on delivering decent living standards, and not copying the affluence and habits of rich countries. Most … [Read more...]
Giving car manufacturers e-fuel credits will slow the rise of EVs
Transport & Environment (T&E) explains why e-fuel credits should not be included in the EUâs CO2 standards for new cars. If they are, it would give carmakers the option to claim an ICE vehicle as low- or zero-emission. But carmakers have no control over what fuel their customers put in their cars, making the regulation impossible to monitor. That opens the door to double-counting emission reductions with other existing regulations (Fuel … [Read more...]
Can Aluminium-air batteries outperform Li-ion for EVs?
Aluminium-air (Al-air) batteries for cars are an innovative technology that automakers and policy-makers should take a close look at, say Helena Uhde and Veronika SpurnĂĄ at ECECP. Although a battery, they behave more like an engine: the fuel is the aluminium which reacts with the air via an electrolyte to produce electric power. Al-air has big advantages over a lithium-ion battery, the favoured choice for EVs. It has a travel range similar to … [Read more...]
Decommissioning coal, oil, gas: how funds can buy and retire the assets
Companies that want to retire their CO2-emitting assets (coal, oil, gas) can struggle to afford the cost of the decommissioning process. Brad Handler and Morgan Bazilian at the Payne Institute for Public Policy, writing for the World Economic Forum, explain how the creation of a new financial instrument, the 'carbon retirement portfolio' (CRP), could be a solution. In essence, itâs simple. Investors create a fund that buys the asset and takes the … [Read more...]
Only Carbon Removal can make Germanyâs new climate goal a reality
Germany canât hit its emissions targets without significant carbon dioxide removal (CRD), explain Simon Göss and Hendrik Schuldt at cr.hub. Clean energy and energy efficiency wonât 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...]
Renewable Hydrogen: what policy instruments are needed to reach the new targets?
A comprehensive mix of policy instruments is needed to ensure that the EU meets its ambitious hydrogen targets. What should they look like? Pia Kerres, Matthias Schimmel and Corinna Klessmann at Guidehouse quote their study, done in collaboration with Agora Energiewende, for the answers. Industry and long-haul transport should be the main customers for hydrogen. The big challenge is to cut the cost of hydrogen production; itâs too expensive and … [Read more...]
