The Machine Sending CO2 to the Ocean and Making Hydrogen

“Equatic’s process works like this: first, it pumps sea water into an electrolyser, a machine that uses electricity to split water into hydrogen and oxygen, which in Equatic’s case is run on clean electricity such as wind, solar or hydro. This converts the seawater to hydrogen gas, oxygen gas, an acid stream and an alkaline slurry of calcium and magnesium-based materials. The alkaline slurry is exposed to air, pulling out CO2 and trapping it, then discharged into the sea. A last step is to neutralise the acid waste stream using rocks (in order to avoid ocean acidification) before this is discharged into the sea too.

The CO2 captured by Equatic ends up in the ocean as dissolved bicarbonate ions and solid mineral carbonates, forms in which the CO2 is immobilised for 10,000 years and billions of years respectively, the company says. ‘In electrochemical methods that convert CO2 into a stable carbon like solid carbonates, the CO2 is locked away permanently,’ agrees Chen. ‘Unless that carbonate is heated to a high temperature of around 900C (1,200K), that CO2 will not be re-released.'”

India Adds Record 24.5 GW of Solar in 2024

“India added 24.5 GW of solar and 3.4 GW of wind capacity in 2024, doubling solar installations and increasing wind capacity by 21% from 2023, according to JMK Research & Analytics. These additions brought India’s total renewable energy capacity to 209.44 GW, with solar accounting for 47% of the total.

The nation’s 24.5 GW of solar capacity additions included 18.5 GW of utility-scale PV, 4.59 GW of rooftop systems, and 1.48 GW of off-grid installations.”

French Power at Record Discount to Germany on Cheap Nuclear

“French year-ahead power prices traded at a record discount to those in Germany, underlining France’s strong nuclear generation and its neighbor’s continued reliance on gas.

French power futures for 2026 are about 27% cheaper than the equivalent contract in Germany, according to data from European Energy Exchange. Nuclear power output in France reached its highest level since 2019 this month, pushing down futures to a three-year low.

While the energy transition may potentially bring lower long-term costs across Europe, the intermittency of solar and wind power means countries are facing short-term price spikes. France has smoothed those out with its nuclear fleet, but Germany is relying on more expensive gas and coal-fired stations after shutting its last atomic plant in 2023.”

Senegal Closing on Universal Electricity Access

“Khady’s story reflects Senegal’s broader journey toward universal electricity access. The country has made significant strides, with a national access rate of 84% according to government sources. This progress has transformed millions of lives, yet the journey is far from over. While urban areas enjoy near-universal access, over 30 % of rural communities remain disconnected from the grid.”

Turkey Doubles Solar Capacity

“Türkiye’s solar energy capacity doubled from 9.7 GW in July 2022 to exceed 19 GW by the end of 2024. By August 2024, the country had already exceeded the 18 GW target set for 2025 in the National Energy Plan (NEP) by the Ministry of Energy and Natural Resources (MENR). Achieving this target 1.5 years ahead of schedule underscores Türkiye’s strong commitment to solar energy and signals the need for more ambitious future targets.

Unlicensed plants, primarily built for self-consumption, accounted for 90% of new installations in the past four years.”
