"The announcement comes as LEGO Group works to achieve a series of sustainability commitments, including its goal to make its products from more sustainable materials, or those produced using renewable or recycled resources and generating little or no waste, by 2032, as well as its targets to reach net zero emissions across the value chain by 2050 and to reduce carbon emissions by 37% by 2032, on a 2019 basis."

"HF Capital has also invested in several energy companies, including Royal Dutch Shell Plc-backed solar developer Silicon Ranch Corp. as well as Arizona DF Renewables, a renewable natural gas producer. Environmentalists have warned that renewable natural gas is still a greenhouse gas, one that is at least 84 times more potent than CO2 when it comes to warming the atmosphere over a 20-year period, though it also qualifies for California’s Low Carbon Fuel Standard."

"Geologic hydrogen — sometimes known as white, gold or natural hydrogen — refers to hydrogen gas that is found in its natural form beneath Earth’s surface. It is thought to be produced by high-temperature reactions between water and iron-rich minerals."

"Exowatt’s system stores that solar energy in a heat battery made of a clay and ceramic composite, a cheap medium that’s readily available in US supply chains, Parvizian said. That heat can be stored for months, but most of Exowatt’s customers are looking for eight to 24 hours of energy to dispatch, allowing them to use it as electricity when other sources are more expensive."

"Blue Frontier, a company based in Florida, is attempting to harness the cooling effects of evaporating water. Its approach makes use of a liquid desiccant, similar to ultra-salty brine, to remove moisture. The dried air is then split into two streams, one of which is passed over a thin layer of water to induce evaporation. This lowers the temperature of the surrounding metal, which in turn cools the other airstream before it is directed back into the room."

"While heat officers can advocate for policies, they often lack decision-making power within a city or regional government."
