I know how hard this is. Hydrogen permeation and embrittlement is no joke. You can resist it with some alloys, but pipelines are on a different level of materials cost than cylinders or chambers.

Agree, hydrogen pipes are typically 4x price of everything else that is expensive. And the normal expensive pricey stuff is 3-6x more than good old carbon steel.

Wow, 100 million households is equivalent to approx. 300 million people!

In China, world’s largest hybrid solar-hydro plant produces electricity on Tibetan Plateau​

• Kela plant in Sichuan is part of a huge renewable production base planned by the Chinese government to generate clean energy for 100 million households
• This technology solves the safe connection of solar power with the grid and prevents wastage, addressing solar power’s inherent dependence on the weather

world's 1st 16MW turbine from GoldWind has been install by Three Gorges Corporation

Unbelievable how large these things are getting

33B RMB invested to produce 50k ton of green hydrogen a year in Inner Mongolia. it will use 3GW of wind/solar power to generate electricity & "world leading" PEM electrolysis technology. not clear where the electrolyzer will purchase from. Cost seems higher due to the high PEM cost.

融科氢能's 120KW、80KW、60KW Fuel cell battery are often used in commercial vehicles, so looks like they will be a customer of this project

Coal prices plummet as green energy surges in China​

Coal prices have fallen to their lowest level since June 2021, primarily due to oversupply and subdued demand from China. Meanwhile, solar power capacity in China doubled that of coal power, with a 33.7% year-on-year growth rate. As China’s commitment to renewable energy strengthens, coal-fired power generation showed a modest 1.8% increase.

first major green H2 project by Sinopec is now online. Talks about the benefits of the project
imo, now that they have this online, this will allow them to develop expertise in managing mega hydrogen projects and build up local supply chain and train workers to use it

China will have the world's largest H2 industry by far

Nitric oxide depletes the ozone layer. Study done on the Tibetan Plateau showed lakes are a bigger contributor than previously thought.

Researchers at the Laboratory for Climate and Ocean-Atmosphere Studies, Peking University, China, and their collaborators have used satellite observations of 135 lakes larger than 50 km2 (this size needed for efficient use of satellite data) to record total nitric oxide emissions of 1.9 metric tons per hour, comparable to the emissions from global megacities. For example, Beijing emits 7.8 tons of nitric oxide/hour, New York City 3 tons/hour, London 1.7 tons/hour and Paris 0.3 tons/hour. It also exceeded emissions from crop fields. For lakes in the south of the Tibetan Plateau, nitrogen dioxide levels were 31.2% higher than their immediate surroundings within a distance of 20 km.

Goldwind Plans to Build USD1.8 Billion Offshore Wind Power Gear Hub in North China


Xinjiang Goldwind Science & Technology, one of China’s biggest wind turbine makers, together with several partners is preparing to invest CNY13.3 billion (USD1.8 billion) to construct an industrial cluster for offshore wind and solar energy equipment in the coastal city of Qinhuangdao, northern Hebei province.

The project will include a wind power core equipment cluster, an offshore wind power and photovoltaic equipment hub as well as an educational training and scientific research base, the Beijing-based company said on June 30.

Goldwind and its partners will be responsible for introducing the wind power projects and will invest up to CNY9.3 billion (USD1.2 billion), it said. The firm will also collaborate with the Qinhuangdao municipal government to attract investors for a solar gear projects with total investment of up to CNY 4 billion. No further details were given.

In addition, Goldwind will work with the local government on the preliminary work for a deep-sea wind energy project, Goldwin said.

Goldwind aims to leverage Qinhuangdao’s excellent port resources and blustery conditions to turn it into the company’s North China manufacturing base for offshore wind power equipment, it said. The project will help improve the firm’s positioning in major coastal provinces to take better advantage of the rapid growth in the offshore wind power market.
