Improving coordination and support for research efforts on climatechange preparedness.
An analysis of near-term spending plans on renewables by the biggest oil and gas companies shows that real investments in renewable energy will continue to pale in comparison to capex plans for greenfield fossil fuel projects. Indeed, much of Big Oil's reduction in greenhouse gas (GHG) emissions leans on the so-called natural gas bridge.
The Dolphyn project showcases a floating semi-submersible design with an integrated wind turbine, PEM electrolysis and desalination facilities. The project concerns the production of hydrogen at scale from offshore floating wind in deep water locations. The hydrogen projects receiving funding are: Dolphyn. Contract value: £3.12
The goal of the agreement is to reduce the greenhouse gas (GHG) emissions in the ocean transportation of sustainable wood pellets. This will include the “Wind Challenger”, a cargo ship design with a hard sail, which would reduce emissions by harnessing wind energy. The first Wind Challenger is scheduled to be released in 2022.

This could save 10 percent of electricity as well, Rahman.
Say Hello to Guest Blogger Alexis Ringwald - with this first dispatch from the ClimateChange Caravan in India. The Climate Caravan includes ten friends and a solar music band, along with three solar plug-in electric Reva cars. We need electric cars for our planet.”. The irony was not lost on any of us.
To solve the climate crisis, we need to cut this in half by 2030, and get to zero by 2050. For electricity generation, this means the United States alone needs to increase renewable-energy capacities by 10 times over the next 12 years , which roughly translates to a mind-boggling 400,000 more wind turbines and 2.5
Natural gas is the fastest-growing fossil fuel, as global supplies of tight gas, shale gas, and coalbed methane increase. The use of liquids declines in the other end-use sectors and for electric power generation. Electricity generation from nuclear power worldwide increases from 2.6
The US and China jointly announced greenhouse gas (GHG) reduction targets. US President Barack Obama said the US will cut net greenhouse gas emissions in the US by 26-28% below 2005 levels by 2025. Together, the US and China account for more than one third of global greenhouse gas emissions.
Even if you have 100 percent capture from the capture equipment, it is still worse, from a social cost perspective, than replacing a coal or gas plant with a wind farm because carbon capture never reduces air pollution and always has a capture equipment cost. In both plants, natural gas turbines power the equipment.
There, d elegations from Azerbaijan, Georgia, Hungary, and Romania finalized an ambitious plan: to generate up to 6 gigawatts of clean energy in the Caucasus region, run the electricity through a cable along the bottom of the Black Sea, and deliver it to Europe. GW , by 2030. That would be enough to supply over 2 million European households.
Recent breakthroughs in separations and catalysis, along with long-trend reductions in solar and windelectricity costs, have significantly increased the potential for cost-competitive renewable fuels from direct air capture (DAC) of CO 2. TW of combined solar and wind capacity for the United States alone will be required.
With government analysis suggesting that 20-35% of the UK’s energy consumption by 2050 could be hydrogen-based, this new energy source could be critical to meet UK targets of net zero emissions by 2050 and cutting emissions by 78% by 2035, the government said—a view shared by the UK’s independent ClimateChange Committee.
The technology group Wärtsilä has issued a report ahead of COP26, the UN’s ClimateChange Conference to be held in Glasgow this autumn, describing the environmental and economic opportunities for states that decarbonize rapidly. coal and gas), significantly reducing the overall levelised cost of electricity.
Life-cycle GHG emissions from fossil and alternative sources of electricity. Lead author Kharecha and colleagues note that current climate science indicates that atmospheric CO 2 concentrations, already at 387 ppm in 2009 and rising, need to be reduced to no more than 350 ppm.

The Rhodium Group, an independent research provider, estimates that, after a sharp uptick in 2018, US greenhouse gas (GHG) emissions fell by 2.1% An increase in natural gas generation offset some of the climate gains from this coal decline, but overall power sector emissions still decreased by almost 10%. Coal-driven decline.
Coal-powered synthetic natural gas (SNG) plants being planned in China would produce seven times more greenhouse gas emissions than conventional natural gas plants, and use up to 100 times the water as shale gas production, according to a new study by Duke University researchers published in the journal Nature ClimateChange.
President Obama’s plan, which sidesteps the need for Congressional involvement by relying on a wide variety of executive actions, has three main components: Reducing greenhouse gas emissions in the US. Preparing the US for the impacts of climatechange. Reducing greenhouse gas emissions in the US.
Under that, the plan sketches out 3 strategic goals: Strategic Objective One: Advance the goals and objectives in the President’s Climate Action Plan by supporting prudent development, deployment, and efficient use of “all of the above” energy resources that also create new jobs and industries.
A new report from the National Research Council examines and, when possible, estimates, “hidden” costs of energy production and use—such as the damage air pollution imposes on human health—that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them.

The recovery of energy demand in 2021 was compounded by adverse weather and energy market conditions—notably the spikes in natural gas prices—which led to more coal being burned despite renewable power generation registering its largest growth to date. CO 2 emissions from natural gas rebounded well above their 2019 levels to 7.5
The world is undergoing an energy transition to reduce CO 2 emissions and mitigate climatechange. At standard temperature and pressure, air is a gas, but under certain conditions, it can become a liquid or solid. The hydrogen is liquefied where electricity is cheap. —Julian Hunt Resources Hunt, J., Montanari, P.,
In Brazil, the rebound of road transport activity after the April low drove a recovery in oil demand, while increases in gas demand in the later months of 2020 pushed emissions above 2019 levels throughout the final quarter. Global emissions from the electricity sector dropped by 450 million tonnes in 2020.

Up to 77% of the world’s energy supply could be met by six key renewables by mid-century under the most optimistic scenario if backed by the right enabling public policies, according to a new report by more than 120 researchers working with the Intergovernmental Panel on ClimateChange (IPCC).
In 2019, CO 2 emissions from petroleum fuels—nearly half of which are associated with motor gasoline consumption—fell by 0.8%, and CO 2 emissions from the use of natural gas increased by 3.3%. Nearly all of the change in CO 2 emissions in 2019 arose in the electric power sector.
Ever since the Copenhagen climate treaty talks ended in impotence two months ago there hasn’t been a single ounce of positive news on the international scene about our chances of cutting the world’s greenhouse gas emissions and getting CO2 levels back down to the safe 350 ppm zone.
The CMA CGM Group has already begun to respond to climatechange by using liquefied natural gas (LNG) as a transitional maritime fuel. As part of the partnership with Engie, its target is to generate 200,000 tonnes of renewable gas per year by 2028, to serve the needs of CMA CGM and the entire shipping industry.
The California Air Resources Board (CARB) announced that greenhouse gas emissions in California in 2016 fell below 1990 levels for the first time since emissions peaked in 2004—a reduction roughly equivalent to taking 12 million cars off the road or saving 6 billion gallons of gasoline a year.
This set of awards supports a diversity of alternative fuel and vehicle types, including biodiesel production, natural gas vehicle technologies and incentives, hybrid and plug-in vehicles, and E85 fueling stations. million as a share of the cost to install 101 new E85 (ethanol) fueling facilities at existing gas fueling stations statewide.
One possible scenario for the electricity system in the Western US in 2026-29.

up to 45%) depending on the extent to which renewable technology costs fall and possible constraints on deployment of low-carbon alternatives, according to the newly released Renewable Energy Review by the UK Committee on ClimateChange (CCC). Gas CCS may be particularly useful in providing flexible generation. Recommendations.
This was the result of growing renewable power generation, switches from coal to natural gas, improvements in energy efficiency, as well as structural changes in the global economy. The decline was driven by a surge in shale gas supplies and more attractive renewable power that displaced coal.
Five of the 28 innovations will help protect the grid from wildfires/PSPSs, four of these five will provide climate and weather risk prediction to electric infrastructure and services, and one is a hard tech innovation to reinforce transmission lines.
Under the scheme, around 500 of the largest emitters in Australia—facilities that have direct greenhouse gas emissions of 25,000 tonnes of CO 2 -equivalent per year or more (excluding emissions from transport fuels and some synthetic greenhouse gases)—will need to buy and surrender to the Government a permit for every tonne they produce.
The report reviews a range of short-, medium- and long-term technologies and examines the advantages and limitations of systems from solar and wind power, through fuel cells to nuclear propulsion.
