Towards the end of this year the EC is expected to issue new proposals for gas legislation, a once in a decade market reform. Simon Skillings and Lisa Fischer at E3G highlight the big difference between the design of gas and electricity markets for Europe. The electricity market is growing, the gas market needs to shrink. The authors quote figures showing that the EU's 55% emissions reduction target for 2030 means natural gas use will reduce by … [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 windâs output falls, nuclear can step in to feed the grid. When itâs 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 â including straightforward thermal power for industry. In collaboration with NREL, the … [Read more...]
Bioenergy is the undervalued pillar of the clean energy transition
Bioenergy is already the worldâs largest source of renewable energy, responsible for 70% of the supply (and around 10% of total primary energy). Burning organic matter goes back to the invention of fire and is still commonplace around the globe. Yet it gets hardly any of the attention and policy support thatâs given to other clean energy technologies like solar, wind and now hydrogen. Bioenergy can and should play an even greater role, explain … [Read more...]
Biofuels vs Hydrogen: which can fuel aviation, shipping, trucks?
The positive signals coming from EV sales and charge points contrast with the lack of progress in finding alternative fuels for aviation, shipping and trucks. Cornelius Claeys runs through the prospects for biofuels and hydrogen to power long-haul transport. Biofuels are already used as a substitute for fossil fuels, and EV uptake will usefully free them for fuelling heavy transport. But as decarbonisation ambitions rise the pressure on scarce … [Read more...]
Hydrogen, CCS, and more: without new clean energy technologies we cannot hit our 2050 emissions targets
The flagship 400-page report, Energy Technology Perspectives 2020, is another salvo from the IEA to concentrate the minds of the world on new technologies and their roll out. Thatâs because transforming electrification and the power sector alone, where most of the progress is happening, will only get us one-third of the way to net-zero emissions by 2050. The IEA has analysed over 800 new technology options. The most important categories â … [Read more...]
Optimising Cyanobacteria for carbon fixation and biofuels
The landscape can be changed for energy transition technologies by research breakthroughs, and that includes work on bacteria and proteins. The National Renewable Energy Laboratory (NREL) and its partners have been running experiments on cyanobacteria. These single-cell organisms, also using photosynthesis, fix carbon dioxide twice as efficiently as plants. They grow rapidly, doubling their numbers in three hours. The first step is to understand … [Read more...]
Tipping Points reached for Solar, Wind, Batteries, EVs. What of the other Clean Energy techs?
History shows a disruptive technologyâs tipping point can be under 5% of market share, thatâs all it takes. The number of horses in use peaked in the U.S. once car ownership reached 3%. Gas lighting in the UK peaked with electric lighting at just 2% of the market. Landline phones in the U.S. fell precipitously after mobiles captured 5% of the market. Ji Chen and Koben Calhoun at RMI argue the tipping point has already been passed for solar, wind, … [Read more...]
IEA projections 2020: energy demand plunges but Renewables still grow at Gas, Coalâs expense
The IEA has made its projections for the impact of the pandemic lockdown on energy demand in 2020 (they say itâs too early for them to assess anything more long term), and its implications for the different generation types. This article summarises their special Global Energy Review 2020, published at the end of last week. It assumes that lockdowns are eased this year and growth gradually returns. With that, global energy demand will fall 6% in … [Read more...]
Defining green investments, ending greenwash: the EUâs new Taxonomy Regulation
When the EU Commissionâs new Taxonomy Regulation is approved, expected in March, it will provide the legal framework to define what is a truly âgreenâ investment. As Luca Bonaccorsi at Transport & Environment explains, right now asset managers and national authorities are free to define what is green, allowing some to greenwash investments in things like oil and pesticides. The Taxonomy's purpose is to reduce ambiguity and therefore increase … [Read more...]
Biofuels âlight-to-powerâ slump: because photosynthesis is no match for Solar PV
The success of energy crops depends on many things. But the first link in the chain is a weak one: natural photosynthesis, the conversion of light into energy by plants. The problem is the efficiency of photosynthesis is no match for that of a modern solar PV cell. And while solar technology keeps improving, mother nature â not a signatory to the Paris Agreement â has no plans to do so. Any progress must come from biotechnology which is slow … [Read more...]
Biofuels: slump in investment and innovations must be reversed
IRENA is predicting the future of liquid biofuels by monitoring the number and technology-type of patents. Itâs not looking good. The first thing to note is that, after a promising rise, the total number of patents has slid from over 6,000 in 2011 to around 2,500 in 2017. Thatâs reflected in the dramatic fall in global biofuel investments, from $27bn in 2007 to $2bn in 2017. The likely main cause is a lack of stable regulation, say Alessandra … [Read more...]
An independent Global Energy Forecast to 2050 (part 5 of 5): Electric cars
Schalk Cloete has completed his own 5-part independent Global Energy Forecast to 2050, to compare with this yearâs IEA World Energy Outlook, published this week. Underpinning all his predictions is his bet that the world will adopt tech-neutral policies (i.e. not backing any one technology over another) in 2030 as the best and only way to accelerate the transition to meet the 2050 goals. Given that, he sees the traditional fossil fuel ICEâs share … [Read more...]
Shipping: commercially viable zero emission deep sea vessels by 2030
Last year the International Maritime Organization, recognising the slow progress the sector had made, set ambitious targets to reduce shipping emissions by at least 50% by 2050 compared to 2008. Companies started lining up to face the challenge. But the shipping sector is very energy intensive. Bunker fuel costs can account for 24 - 41% of total shipping costs, so any clean fuel transition must be competitively priced. The fact that alternatives … [Read more...]
German task force agreement on traffic emissions 1/3 off target
During what was billed as the decisive meeting, the German transport commission charged with proposing emissions cuts for the sector could only reach consensus on measures that will lower emissions by around two thirds of the necessary amount. Pro-climate activists, disappointed with the results, nevertheless welcomed the recommendation to look into the introduction of a CO2 price. Meanwhile emissions have actually increased. And VW, siding with … [Read more...]
Study says no way to decarbonise the gas sector by 2050
Gas industry advocates argue that expansion of gas infrastructure is justified because it will be possible to switch to low-carbon gases such as hydrogen and biomethane in future. But research by the International Council on Clean Transportation (ICCT) predicts that biomethane production will remain modest, even with massive subsidies. … [Read more...]
