green hydrogen

Underwater gravity energy storage has been proposed as an ideal solution for weekly energy storage, by an international group of scientists. The novel technology is considered an alternative to pumped-hydro storage for coasts and islands without mountains that are located close to deep waters, and may also be interesting for PV if used to store green hydrogen.

The European Commission will propose a number of new laws this summer and fall that are set to boost investment in renewable electricity and green hydrogen, reports Andreas Walstad in Brussels.

Moreover, Landsvirkjun, the National Power Company of Iceland, and the Port of Rotterdam have completed a pre-feasability study about exporting green hydrogen from Iceland to Rotterdam and the Swedish Energy Agency has allocated €30 million to Project Air, an industrial concept to produce methanol from a large variety of recovered end-of-life streams and hydrogen from electrolysis.

If the three record-busting low solar price tariffs recorded in the Middle East in the past 18 months are to be believed, renewables-powered hydrogen in prime sites in the region could already compete with gas-plus-CCS production, according to IRENA. Has the Gulf discovered the new petrol?

A 1 MW electrolyzer in the middle of a residential area in Esslingen, southern Germany, is intended to significantly reduce the carbon footprint of its residents. One of the energy sources used in the project is rooftop PV located in the area.

Israel-based GenCell has unveiled an off-grid hydrogen power solution based on alkaline fuel cell (AFC) technology. Italian energy giant Enel and Russian technology company Rusnano want to set up Russia’s first green-hydrogen production project at a wind farm in the Murmansk region.

Italian hydrogen and fuel cells association H2IT is urging the national government to support investment in green hydrogen and ensure medium-long payback periods. The trade body’s goal is to build large-scale electrolyzers (>100 MW) to decrease green hydrogen’s price below €2.0/kg.

Australia-based TNG Limited has signed an agreement with Malaysian green hydrogen company AGV Energy which will see its vanadium redox flow batteries integrated into the HySustain project to store solar energy for green hydrogen production.

The murkiness of the federal government’s drive to make Australia an exporter of hydrogen, of any hue, gives rise to concerns.

Furthermore, Germany-based large-bore diesel engines and turbomachinery company MAN Energy Solutions is acquiring the majority of shares in the Augsburg-based electrolyzer manufacturer H-TEC Systems, while the India H2 Alliance is expanding with the aim of building consensus for a common path towards hydrogen commercialization in India’s steel and cement sectors.
