Heating Buildings With Solar Energy Stored in Sand

Cars That Think

In a region known for long, dark winter nights, Polar Night Energy is building a system in the city of Tampere that can heat buildings with stored solar energy — all day, all night, and all winter long. Out of Finland’s energy-related emissions, 82 percent come from heating domestic buildings (Ref.

MITEI study finds hydrogen-generated electricity is a cost-competitive candidate for backing up wind and solar

Green Car Congress

A team at MITEI (MIT Energy Initiative) has found that hydrogen-generated electricity can be a cost-competitive option for backing up wind and solar. California draws more than 20% of its electricity from solar and approximately 7% from wind, with more VRE coming online rapidly. —Drake Hernandez.

Wind-to-Hydrogen Tech Goes to Sea

Cars That Think

Wind and solar parks produce a large portion of their energy. Then, as now, wind farms are operating off the world’s coasts—but not all of these offshore sites are connected to the mainland via underwater power cables. Some of the wind farms instead sit in clusters more than 100 kilometers out at sea.

Watch the world’s first artificial energy island being built [video]

Baua Electric

Princess Elisabeth Island will be an electricity grid at sea that will connect offshore wind farms to the Belgian mainland and also serve as a hub for future interconnectors with the UK and Denmark. It takes around three months to build one caisson. The production process is split into five 20-day stages. Get started here. –ad*

IEA: nuclear power can play a major role in transition to low emissions energy systems; Russia, China leading on new reactor starts

Green Car Congress

In countries that choose to continue or increase their use of nuclear power, it can reduce reliance on imported fossil fuels, cut carbon dioxide emissions and enable electricity systems to integrate higher shares of solar and wind power.

New Water Oxidation Catalyst Could Boost Potential for Solar Production of Hydrogen

Green Car Congress

Chemists from Emory University and the Paris Institute of Molecular Chemistry have developed a stable and fast homogeneous water oxidation catalyst (WOC), considered a crucial component for generating hydrogen using only water and sunlight, that is easily prepared from readily available salts and oxides of earth abundant elements.

Anaergia to supply CO2 to European Energy A/S for green e-methanol production as fuel for container ships

Green Car Congress

European Energy, a major multinational renewable wind and solar energy producer, will produce green e-methanol from this biogenic CO 2. Owing to this agreement with European Energy, Anaergia will build a CO 2 liquification system at the plant. Under the terms of an agreement European Energy had previously entered into with A.P.
