Large scale electricity generators, unconcerned with end-use, want to sell you more electricity, argues Walt Patterson of the Hoffmann Centre for Sustainable Resource Economy, based at Chatham House. But the arrival of small-scale, localised and micro-grid suppliers could see the electricity generation business turned on its head. It opens the door to the selling of the service – light, heat, refrigeration, motive power, information – rather than … [Read more...]
Will Toyota’s new battery design solve the looming shortage of vital metals for renewables?
We all know the important part played by lithium in battery manufacture. But there is a longer list of metals - including copper, cobalt and neodymium – that must ramp up supply for the continued rapid growth of EVs, solar, wind and other renewables technologies. EVs alone will increase the consumption of copper nine-fold by 2027. Cobalt prices already doubled in 2017. Neodymium use will rise by 700% in the next few decades to satisfy our need … [Read more...]
IEA: Battery storage races to keep up with solar and wind’s demand-matching challenges
Yesterday’s article from the IEA posed the question: will solar’s inherent intermittency slow its rise as a major power supply. For variable renewables like solar and wind to grow to over 50% of global capacity additions by 2040, storage technology must keep up with this pace. For this to happen, “flexibility” – the ability of the power system to quickly adapt to changes in power supply and demand – needs to grow by some 80% in the next decade … [Read more...]
EXCLUSIVE: Geothermal could represent a far bigger share of renewables
The IEA says geothermal energy could account for only 3.5% of annual global electricity production and 3.9% of energy for heat (excluding ground source heat pumps) by 2050. But is this down to short term thinking? Geothermal could make a much bigger contribution to renewables, provided it is put onto the fast track like wind and solar, says Alexander Richter, President of the International Geothermal Association. … [Read more...]
Renewables for remote mines power supply in Africa gaining momentum
In the last few years, more and more mining companies have adopted wind and solar systems to reduce their energy costs at remote off-grid mines. In this first phase, the initial focus was on the integration capabilities as miners were afraid that adding intermittent renewables such as solar and wind could affect the reliability of power supply and even lead to production losses. In various microgrid applications, renewables combined with … [Read more...]
Digitalisation is changing the energy landscape
The energy sector is already using data in sophisticated ways to meet a wide range of challenges, from fault prediction in grid networks to the delivery of personalised energy to households. As more data becomes “big data” and smart devices proliferate along the value chain, Matt Brown and Ravi Mahendra of Pöyry Management Consulting make their predictions for more digitalisation in the coming year. … [Read more...]
New tool to show whether companies’ climate strategy matches their public ambitions
By now we’re used to stats that show what would happen if everyone in the world had the same carbon footprint as a European, or an American, someone in China, or indeed anywhere. According to the consultancy right. based on science, they have now created a way of modelling the same projections, except for specific companies. The model also number-crunches a company's climate strategy to work out whether they are going to help or hinder the race … [Read more...]
The compelling case for carbon capture and storage
By 2040 60% of primary energy will still come from fossil fuels, says the IEA. That means Carbon Capture and Storage (CCS) must be part of the technology mix to hold back climate change. Yet today there are only 18 CCS facilities in operation, with 25 in the pipeline. We’ll need at least 2,000 by 2040. Brad Page, CEO of the Global CCS Institute, lays out the reasons why we have no time to lose. The World Economic Forum’s meeting in Davos … [Read more...]
Too “low-hanging fruit” is not sweet enough (and eventually neither clean nor cheap)!
At a lunch debate organised by the European Heat Pump Association (EHPA) on “The costs of a low level of ambition in greening the heating and cooling sector” and hosted by EUFORES President MEP Jeppe Kofod on 30 January, representatives from industry, civil society, the European Commission (EC) and MEPs from several countries and political groups (Jeppe Kofod, Bendt Bendtsen, Theresa Griffin, Jo Leinen, Gesine Meissner and Paul Rübig) … [Read more...]
Online Brine Platform Boosts Circular Economy Solutions for Process Industries
The ZERO BRINE project, which aims to advance circular economy business models by redesigning the value and supply chain of water and minerals through the recovery of resources from brine generated by process industries, has announced the release of its The OBP is an interactive web service that connects brine owners with mineral and water users and technology providers to promote the reuse of secondary raw materials and water. Through the OBP, … [Read more...]
Solar energy is green. Solar panels are not. AI can revolutionise their design
Solar panels are manufactured at 2,000˚C, a temperature so high it requires fossil-fuel power. They are also made using rare earth elements, the supply of which has both capacity and political issues. A new and global project is using artificial intelligence (AI) to rapidly create new designs with new materials that can make their manufacture greener and cheaper. The new designs may even bring their manufacture back to your home country, says … [Read more...]
Carbon taxes aren’t working any more. Only ramping up policies and infrastructure can accelerate the transition
Anthony Patt and Johan Lilliestam of ETH Zurich make the case against carbon taxes. Climate policy is most effective when it helps people use alternative energy sources, rather than when it makes fossil energy more expensive. Fostering an energy system free of fossil fuels requires financial, infrastructure, and institutional support for specific technologies. That requires a different and much braver approach. Reducing or eliminating carbon … [Read more...]
Solar farms getting smaller, cheaper and smarter to overcome grid hurdles
The technical challenges and fast-changing regulatory requirements associated with installing and integrating variable RES capacity are inevitably holding up the transition to clean energy all around the globe. So the announcement of a new smart solar farm in Australia that seems to have overcome these hurdles is really good news. The situation has been neatly captured across a number of recent reports (summarised here) by Giles Parkinson of … [Read more...]
EU should target carbon dioxide removal as part of net zero emissions strategy
Carbon Dioxide Removal (CDR) technologies are still in their infancy. However, they are an essential part of limiting global temperature increases to 1.5-2°C to meet the Paris Agreement’s objectives. So what is the best way to ensure CDR is ramped up at the right speed to hit those targets, and avoid the “moral hazard” of the promise of future CDR giving others an excuse to fail with their straightforward carbon reduction? Oliver Geden, Glen … [Read more...]
Solar panels replaced tarmac on a road. Here are the results
Using roads for solar energy generation is one of those ideas that makes engineers frown but seems to capture the public imagination, with an Indiegogo fundraising campaign for the concept pulling in almost $2.3m in 2014. But now the idea is being put into practice it appears the engineers may have been right all along, according to Dylan Ryan of Edinburgh Napier University.
