For an electrolyzer to work with electricity from the grid, it needs a rectifier. The rectifiers work, in essence, like a photovoltaic inverter – but the other way around. Several companies from the solar industry are now active in this area. Positive side effect: Your technology is inherently network friendly. (more…)
The realization that we need a lot of green hydrogen very quickly, not only in Germany and Europe, but also worldwide, is becoming more and more widespread. Germany has already made the decision to phase out nuclear energy and coal. And after Putin’s attack on Ukraine, natural gas is also under examination. The plan was to make the gas grid greener and greener. Now, there is discussion about a much faster ramp-up of the hydrogen economy. Which scenarios are conceivable for this? (more…)
In November 2021, the Namibian government issued a notice of award stating its intention to appoint Hyphen Hydrogen Energy as the preferred bidder to develop a hydrogen project in the Tsau Khaeb National Park. The project, worth an estimated USD 9.4 billion, will produce 300,000 tons of green hydrogen per year and will see the installation of 3 gigawatts of electrolyzer capacity and 5 gigawatts of wind and photovoltaic generating capacity by the end of the decade. Hyphen is a joint venture between Nicholas Holdings and Enertrag South Africa, a subsidiary of German company Enertrag. This initiative is part of the H2Global program (see H2-international, October 2021).
The development of a real prototype is time-consuming and expensive. Mathematical models make it possible to better understand the physical and chemical processes in a fuel cell or an electrolyser. A simulation helps to create new approaches and designs in Lobar. (more…)
Fifth part of the Regions series: HyStarter Rügen-Stralsund
What role can the production of green hydrogen play in the future for regional added value creation in a rural, structurally weak, but large area region with a high share of renewable energy production capacities? Which generation paths make sense at different locations, and which framework conditions must be fulfilled in order to achieve this? Where is there potential for hydrogen applications in the district of Vorpommern-Rügen? With these questions in mind, the HyStarter Region Rügen-Stralsund started a one-year strategy process in December 2019 to develop a vision, define fields of action, analyse selected locations and technology concepts, and adopt a roadmap until 2030 that describes a whole bundle of measures to be implemented in the future.
