Hydrogen

Innovations in green hydrogen are developing at a fast pace. This presents new questions like where are the markets, how fast will they come, how can we ensure hydrogen is green and cost-efficient, and what needs to be considered by project developers when planning related business models? And, at the end, will there be an opportunity for market players coming from the solar sphere? Watch our final Roundtable Europe video to find out.

German project developer Svevind Energy and Kazakh Invest wants to build a 45 GW green hydrogen complex in Kazakhstan. Norwegian companies Equinor, Aker Group and Saga Pure announced separate plans to further develop their green hydrogen solution.

Electricity bill payers in nations as diverse as Germany, Greece, India and China should be aware new solar projects can now generate electricity cheaper for them than legacy coal and gas-fired plants.

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.

According to a new study from a German-Swedish research group, conventional incentives such as renewable portfolio standards, feed-in tariffs or feed-in premium payments may likely lead to a price cannibalisation scenario for wind and solar. CO2 pricing, instead, is considered an efficient tool to maintain their market value high enough to ensure new investments. However, a total system cost approach, rather than an LCOE perspective, is needed to understand the strong dependence of market value on policy choice.

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.
