Running cars on E-Fuels, made with CO2 from the air and green Hydrogen?🚗⛽🌿⚡
E-Fuels, so the story goes, could allow using existing cars and infrastructure like gas stations. However, E-Fuels are extremely inefficient.
In 2022, Siemens Energy, Porsche, and the Chilean company HIF inaugurated the Haru Oni pilot plant in Chile's windy Magallanes region, which turns CO2 and Hydrogen into Methanol and small amounts of Gasoline. How's it going? 🧵

What's up with the Production of E-Fuels in Chile?
In 2022, Siemens Energy, Porsche, and HIF inaugurated a pilot plant for the production of E-Methanol and E-Gasoline in southern Chile. The Haru Oni plant was intended to be just the beginning — with plans for large-scale production just a few years later. However, it does not look like that will ever happen.

It's Not Easy Being Green: On the Energy Efficiency of Programming Languages
Does the choice of programming language affect energy consumption? Previous highly visible studies have established associations between certain programming languages and energy consumption. A causal misinterpretation of this work has led academics and industry leaders to use or support certain languages based on their claimed impact on energy consumption. This paper tackles this causal question directly. It first corrects and improves the measurement methodology used by prior work. It then dev…

Energy Efficiency Analysis of Active RIS-enhanced Wireless Network under Power-Sum Constraint
Recently, as a green wireless technology, active reconfigurable intelligent surface (RIS) attracts numerous research activities due to its amplifying ability to combat the double-fading effect compared to passive one. How about its energy efficiency (EE) over passive one? Below, the EE of active RIS-aided wireless network in Rayleigh fading channels is analyzed. Using the law of large numbers, EE is derived as a function of five factors: power allocation factor, the number (N) of RIS elements, …

Uncovering relationships between the electronic self-energy and coupled-cluster doubles theory
We derive the coupled-cluster doubles (CCD) amplitude equations by introduction of the particle-hole-time decoupled electronic self-energy. This leads to an alternative ground state correlation energy obtained from the Green's function formalism which is exactly of the form obtained in coupled-cluster doubles theory. We demonstrate the relationship to the ionization potential/electron affinity equation-of-motion coupled-cluster doubles (IP/EA-EOM-CCD) eigenvalue problem by coupling the reverse-…

I got myself a portable solar panel, which I can use while camping and at home for charging power banks. I’m very impressed with how well it works, even on a cloudy day! The purpose of the panel is basically to power my power banks so I have green energy to charge my phone, tablet, headphones, USB lights, and electric toothbrush. It’s not much, but every bit helps to keep the bill lower.

Applying the ACE2 Emulator to SST Green's Functions for the E3SMv3 Global Atmosphere Model
Green's functions are a useful technique for interpreting atmospheric state responses to changes in the spatial pattern of sea surface temperature (SST). Here we train version 2 of the Ai2 Climate Emulator (ACE2) on reference historical SST simulations of the US Department of Energy's EAMv3 global atmosphere model. We compare how well the SST Green's functions generated by ACE2 match those of EAMv3, following the protocol of the Green's Function Model Intercomparison Project (GFMIP). The spatia…

Nonequilibrium transport through the Hubbard dimer
We apply a computationally efficient approach to study the time- and energy-resolved spectral properties of a two-site Hubbard model using the nonequilibrium Green's function formalism. By employing the iterative generalized Kadanoff-Baym ansatz ($i$GKBA) within a time-linear framework, we avoid the computational cost of solving the full two-time Kadanoff-Baym equations. Spectral information is extracted by coupling the system to multiple narrow-band leads, establishing a direct analogy to phot…

From the BC Green Party
Premier David Eby is seriously considering a fossil fuel megaproject that would sell out BC’s energy future to Donald Trump’s corporate allies.
The Prince Rupert Gas Transmission (PRGT) pipeline is backed by MAGA-linked billionaires and would transport fracked gas across Northern BC to a new LNG terminal.
Eby himself once said that we can’t keep building fossil fuel projects and still meet our climate goals. So why is his government even considering t…

“An assessment of updated National Climate and Energy Plans (NECPs) shows the EU is on course to achieve a 54 per cent emissions reduction by 2030 - just one per cent shy of its legally binding 55 per cent target.”
Fun fact, if Canada joined the EU it would probably hurt it from an emissions reduction perspective because Oil and Gas.
“It attributed the progress towards the 2030 goal to action in the energy sector, with renewables covering 24 per cent of energy consumption in the EU in 2023. Most member states are now aligned with the target of reaching a share of 42.5 per cent by 2030, according to the Commission.”
Weird how they don’t mention LNG as being a reason why Europe has been able to meet its goals. Almost like renewables are essentially the only way to decarbonize the industry, just like the scientists say it is.
“States have a legal obligation to deliver climate action, and the Commission has a clear responsibility to uphold and enforce EU law in response.”
