green hydrogen

Bosch’s new solid oxide fuel cell prototype has an electrical efficiency of more than 60% and an overall efficiency above 85%. It also has a targeted power output of 10 kW and can produce up to 3 kW of thermal energy.

Scottish Development International and J-DeEP are developing a floating offshore hydrogen production plant off the coast of Scotland. Research shows the combination of large-scale offshore renewables and floating hydrogen production could soon become viable, depending on the project configuration.

Researchers in Mexico have looked at integrating hydrogen-based power-to-gas-to-power into an existing rural microgrid. They said this solution could become competitive if electrolyzer, fuel cell and hydrogen tank costs are halved, or if diesel prices keep rising.

Photovoltaics can wipe out 4.25 billion tons of carbon emissions every year this decade, according to the UN Intergovernmental Panel on Climate Change. Even so, the actions announced so far remain way short of what is needed, with capital flows to fossil fuels still greater than the cash directed toward combating climate change.

The Berlin Energy Transition Dialogue 2022 event has shown the centrality of renewables and green hydrogen in the world’s future energy landscape. pv magazine spoke with the General Director of the International Renewable Energy Agency, Francesco La Camera, about the difficulties of creating a hydrogen economy in the absence of demand. According to him, public support and policies will be crucial to overcoming this challenge.

Only by working together can African nations overcome the obstacles to exploiting their abundant renewables resources and producing affordable green hydrogen – for use at home and in a European economy keen to wean itself off Russian gas, an online event has been told.

A new deal between Fortescue Future Industries and E.ON will see the Australian company deliver 5 million tons of green hydrogen to Germany, the Netherlands, and multiple cities in Europe by 2030.

Western Australian company Global Energy Ventures has had several permissions granted for its 2.8GW green hydrogen export project on the Tiwi Islands, off the coast of the Northern Territory, including potentially increasing the acreage for its proposed solar farm.

The developer last year sold off 2.9GW of solar generation capacity to state-owned entities to reduce its debt pile by $1.76 billion and has another 298MW up for sale as it repeated its intent to switch to blue, and later, green hydrogen.

German scientists have tried to determine whether a PV system linked to a small electrolyzer, a fuel cell, and lithium-ion batteries could fully power a grid-connected household. Their new proposal consists of a 6.8kW PV array, a 5kW electrolyzer, a 1.24kW fuel cell system, and battery storage.
