The international shipping sector’s emission levels are comparable to Germany’s. Like aviation and heavy transport, reaching net-zero will need renewable fuels – direct electrification won’t be sufficient. Existing fossil fuel engines allow for biofuel blends of up to 20% without any modifications, and 100% methanol engines are a proven technology. Making sufficient quantities of clean fuels - without consuming food crops – is the challenge. … [Read more...]
Decarbonising Industry is key to China’s net-zero strategy
China has committed to a CO2 emissions peak before 2030 and carbon neutrality before 2060. It’s 14th 5-year plan will be released in March, followed by sector-oriented plans. For the first time it will include a dedicated plan addressing climate change. Dolf Gielen, Yong Chen and Paul Durrant at IRENA start by laying out China’s energy mix for scrutiny, then dive into its industrial sector which accounts for 60% of gross final energy use. Success … [Read more...]
An EU Hydrogen strategy: from industry feedstock to energy vector
The bravest recovery strategies will invest robustly in new yet-to-take-off clean energy technologies. If you are going to have to spend hundreds of billions to revive your economy isn’t it better to replace the old with the new rather than prop up what you’ll have to abandon soon anyway? In anticipation of that happening, new technologies are lining up. Here, CĂ©dric Philibert at the IFRI Centre for Energy & Climate summarises their detailed … [Read more...]
The outlook for Powerfuels in aviation, shipping
The development and commercialisation of powerfuels is in its very early stages. Powerfuels are synthetic gaseous and liquid fuels produced from green electricity. The plan is to use them when there is no viable alternative, like aviation and shipping. The big hurdle is cost, currently in the range of €3-5/litre, or five to ten times the price of fossil fuels. Dolf Gielen and Gabriel Castellanos at IRENA and Kilian Crone at the German Energy … [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...]
New gas-to-methanol technology OxE could end oil well “flaring”
Oil wells also release natural gas. But it’s burnt off on site whenever the economics of collecting and piping it don’t add up (gas can’t use the existing petroleum infrastructure). What if it could be converted into methanol, says Nichole Liebov at the University of Virginia. She describes a new process called oxyesterification (OxE) that converts methane (the main constituent of natural gas) into methanol cost effectively at low temperatures … [Read more...]
