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. It must deliver power to people when they need it, where they need it, and at a manageable price.

Gas War: U.S. Oil Companies Accused of Price Fixing With OPEC, Increasing Inflation

The Truth About Cars

shale oil firms purposefully colluded with the government of Saudi Arabia to fix oil prices between 2021 and 2023. From BIG : Yesterday, the Federal Trade Commission released evidence confirming that collusion played a serious role in hiking oil prices at that time. Once that price war ended, presumably so did the savings.

BNEF report finds hydrogen promising decarbonization pathway, but carbon prices and emissions policies required

Green Car Congress

This is equivalent to gas priced at $6-12/MMBtu, making it competitive with current natural gas prices in Brazil, China, India, Germany and Scandinavia on an energy-equivalent basis. Renewable hydrogen can be made by splitting water into hydrogen and oxygen, using electricity generated by cheap wind or solar power.

Wärtsilä, Höegh LNG and partners receive funding of €5.9M to develop ammonia as hydrogen carrier

Green Car Congress

However, it is difficult to store and transport due to its low volumetric energy density and with potential large vaporization losses. Ammonia is significantly better suited than hydrogen for this purpose, since it can be stored in liquid form at moderate pressures and temperatures.

PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

By using a water-lean post-combustion capture solvent, (N-(2-ethoxyethyl)-3-morpholinopropan-1-amine) (2-EEMPA), they achieved a greater than 90% conversion of captured CO 2 to hydrocarbons—mostly methane—in the presence of a heterogenous Ru catalyst under relatively mild reaction conditions (170 °C and 2 pressure).

New $30M ARPA-E program to produce renewable liquid fuels from renewable energy, air and water

Green Car Congress

The US Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) announced up to $30 million in funding for a new program for technologies that use renewable energy to convert air and water into cost-competitive liquid fuels. ( kWh—the price needed to be competitive with other carbon-free delivery methods.
