The Namibian government has approved an agreement with Hyphen Hydrogen Energy to develop and operate the largest green hydrogen project in sub-Saharan Africa. With a total capital investment of US$10 billion, the project is expected to produce 2 million tons of green ammonia per year for the regional and global markets.

Plug Power has signed three 5MW electrolyser projects with Sweden's Ardagh Glass Limmared, Norway's Hydro Havrand and Germany's APEX Group. These projects mark the first applications of large-scale green hydrogen in glass manufacturing, aluminum recycling and steel production. With a production capacity of over 2 tonnes per day, Plug Power says its standardized turnkey systems are unrivaled in the market.

ThyssenKrupp Nucera has partnered with H2 Green Steel to build Europe's first large-scale green steel plant. The project in Boden, northern Sweden, will deploy standardized 20 MW electrolysis modules, bringing the capacity to over 700 MW. Thyssenkrupp Nucera said the partnership will also create one of the largest water electrolysis facilities in Europe. The plant will begin operations at the end of 2025 and gradually expand in 2026. In the initial phase, the plant will produce 2.5 million tons of green steel, which is expected to increase to 5 million tons by 2030.

An international research team has proposed using solid nitrogen or oxygen to recover cold energy in the hydrogen liquefaction supply chain. The researchers, from Austria, Brazil, China, Saudi Arabia and South Korea, say the process involves hydrogen regasification on arrival to produce solid nitrogen or oxygen. These solids are then transported back to the hydrogen liquefaction facility within the liquid hydrogen carrier, effectively reducing energy consumption for cooling gaseous hydrogen. They noted a significant energy reduction of 25.4% with N2 and 27.3% with O2. The team concluded that solid-air hydrogen liquefaction could serve as an important component of the global hydrogen economy.Editor/XingWentao
