There are more than 3m telecom towers globally, and powering them is a $100bn market. It's a particularly important growth sector in developing countries. They are already using mobiles to leapfrog the laying of costly landlines, but because they lack grids that stretch to remote communities they need to power towers that are off the grid. Dr Thomas Hillig says as solar and storage costs continue to drop they are replacing diesel gensets as the … [Read more...]
European Commission’s decision to approve Poland’s capacity mechanism challenged
Electricity generators can pitch for awards from governments operating capacity markets. Capacity markets establish a price (at auctions) for back-up power which may, or may not, be needed. Either way, the operator of the power plant gets paid for guaranteeing security of supply to the grid. Last year, the European Commission approved the Polish capacity market and, according to CAN Europe, in its first auction the Polish government awarded 22,4 … [Read more...]
IEEFA: IEA’s Sustainable Development Scenario is not enough
The IEA’s Sustainable Development Scenario (SDS) – if it’s followed - sees the world limiting the temperature rise to below 2°C. Even if we stick to the plan the SDS gives us only a 50% chance of success. Tim Buckley at IEEFA says those odds are not good enough. Worse, the SDS depends on carbon capture and storage (CCS) achieving commercialisation at scale by 2030. The author explains why he thinks that’s unrealistic, and calls for the IEA to … [Read more...]
EU election risk: policymakers should go for real decarbonisation now while efficiency savings can help
With elections in May, the balance of opinion in Parliament is a climate policy risk factor on the minds of many in Brussels. The national draft 10-year energy plans, just in to the Commission, project widespread growth in costlier renewables. But populists who see climate as a globalist rather than nationalist-first agenda may prove hard to bring on side with an expensive and disruptive transition. The public will be influenced by climate … [Read more...]
Virtual power plants: a story of market rules and smartgrids
Access to the grid-balancing market is competitive and carefully regulated. Green electricity from distributed and behind-the-meter renewable assets is already being traded on wholesale and balancing markets. The assets come in all shapes and sizes: roof-top solar, farmyard biofuel installations, EV and home battery systems, community energy projects, wind installations and heat pumps to name but a few. When they are pooled, by aggregators, they … [Read more...]
Renewable hydrogen “already cost competitive”, says new research
Jocelyn Timperley at Carbon Brief has interviewed the lead author, and the critics, of this new report titled “Economics of converting renewable power to hydrogen”. The research says renewable hydrogen is already proving competitive for niche, high-intensity users in Germany and Texas. Future technological improvements, combined with expected changes to subsidies and CCS requirements, can make it so for large-scale industrial users in the next 10 … [Read more...]
Clean air transport: batteries or biojet or both – but let’s get on with it
In his last article for Energy Post, Mike Scott looked at how airlines are under increasing pressure to reduce their greenhouse gas emissions rather than offsetting them as they do now. How can it be done? There is no one-size-fits-all solution for the varied size of aircraft and flight distances but that should be no excuse. Battery innovation offers solutions for some cases whilst biojet (aviation biofuel) can fill many of the remaining gaps. … [Read more...]
U.S. innovative financing makes buildings energy efficiency affordable even to poor communities
Buildings energy efficiency is not moving fast enough to meet the Paris Agreement goals. Retrofitting old buildings is extremely costly and needs much more investment, as our previous articles have detailed. Innovative models of financing are urgently needed. In an article for Ensia, Nate Berg explains how by rolling upgrade costs into monthly bills for poorer communities, U.S. utilities are helping customers save energy and money at the same … [Read more...]
Flexible renewable power: Spain to triple solar thermal capacity by 2030
Sunny Southern Europe will become increasingly connected to its Central and Northern European neighbours with the ongoing development of cross border interconnectors. This is one of the crucial factors behind Spain’s decision to include an additional 5 GW capacity from STE/CSP plants in its Integrated National Energy and Climate plan (NECP). Complete with inherent storage capabilities, STE can provide flexible, dispatchable power supply at … [Read more...]
Utilities are starting to invest in big batteries instead of building new power plants
There has been a dramatic drop in battery costs in recent years. Jeremiah Johnson and Joseph F. DeCarolis, of North Carolina State University, say if this continues grid-scale batteries could supplant the usual solutions to peak electricity demand: gas power plants and transmission lines. Inevitably, this will depend on the future price of gas, and the changing policy environment. But one thing is for sure: utilities don’t want to invest in peak … [Read more...]
Climate Auctions can reduce emissions and accelerate regulatory, financial and infrastructure goals
Auctions for delivering an amount of power at a defined price are already well established for renewables. “Climate Auctions” do the same with carbon emissions: a carbon price is guaranteed to the winning bidder, but only paid on delivery of the emissions cut. Tyeler Matsuo and Julia Meisel at Rocky Mountain Institute say this is proving particularly useful in emerging and developing countries where progress in building up their climate laws is … [Read more...]
Energy Data prototype: the “Living Lab” households
Everyone in the energy sector is talking about big – and intelligent – data. But it’s still early days and the benefits from all that potential are yet to register. The goal is greater energy efficiency; in consumption but also in planning future infrastructure and services that are tailored to local – not just regional - needs. Smart meters are only the first step, says Dr Richard Dobson at Energy Systems Catapult. The end game is the emergence … [Read more...]
Airline emissions: pressure is on to reduce, not offset
Oil and gas, shipping, utilities, automotive – the list of sectors that investors have turned their spotlight on to examine their impacts on climate change is growing all the time. The latest to come under pressure is aviation. The airline sector currently accounts for 2% of global CO2 emissions and 12% of transport-related CO2 emissions and its share of total emissions is growing fast. In addition, aviation has climate impacts beyond CO2 … [Read more...]
Green Oil: second wave of investment in low-carbon assets is substantial but hardly tidal
Oil majors are under significant pressure from investors to develop climate-friendly business areas but less than 1.5% of their combined investment budgets is expected to go into low-carbon assets globally this year. However, 70% of that is set to come from European oil companies who are reacting positively to market signals by participating in coordinated industry schemes designed to help meet Paris targets. Here is an overview of some of the … [Read more...]
Transition: nation-by-nation review of race to phaseout coal
The global effort to phase out coal consumption is speeding up. However, a lot of necessary work is still to be done, both to align with the ambition of the Paris Agreement and to ensure a just transition for affected workers and citizens. Oliver Sartor at the IDDRI runs through the leading examples of coal's phase-out across the world, nation by nation, and warns that coal producing and consuming countries that do not adapt are in danger of … [Read more...]
