Energy Storage

The Japan Organization for Metals and Energy Security (Jogmec) and Germany’s H2Global Foundation have agreed to cooperate on clean hydrogen, while officials from Japan and South Africa met this week to discuss hydrogen collaboration opportunities.

LG has developed two versions of its new enblock E storage system, each with usable energy capacities of 12.4 kWh and 15.5 kWh. It says the two models, sized at 451 mm x 330 mm, can be easily deployed in small spaces.

Scientists have proposed to use PV energy and heat pump-driven HVAC system in greenhouses conceived to grow tomatoes in the Mediterranean area. The system was found to have a payback time of only 2.9 years in southern Spain.

A new Stanford University report shows that the transition to clean energy could help many countries to reduce their annual energy costs by around 61%.

Tripling clean energy generation capacity to 11 TW by 2030 was a leading pledge from the United Nations’ (UN) climate change conference in Dubai. With few details about infrastructure and energy storage and no clear PV targets, however, it is hard to judge the effectiveness of the 28th global Conference of the Parties (COP) meeting. Angela Skujins considers possible impacts for the solar industry.

The US Department of Energy (DoE) has announced plans to invest $20 million in 16 projects across eight states to accelerate the exploration of geologic hydrogen.

Scientists from China have developed a novel optimization method for medium-depth ground source heat pumps, using an improved chaos particle swarm optimization. They coupled it with either a heat storage tank or a shallow borehole heat exchanger and found that both system typologies increase the heat pump’s coefficient of performance.

Zaha Hadid Architects has unveiled the world’s first green hydrogen refueling network for recreational boats at marinas in Italy, while a German-Czech consortium has announced the development of a drivable hydrogen motorcycle.

Alternatives to lithium-ion batteries will likely emerge in the years to come, according to a new report by IDTechEx.

Researchers in Norway have investigated the technical potential of implementing subsea pumped hydro storage at water depth not exceeding 2,000 m. They also identified potential locations for these storage systems based on energy density.
