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

Green Car Congress

The falling cost of making hydrogen from wind and solar power offers a promising route to cutting emissions in some of the most fossil-fuel-dependent sectors of the economy, such as steel, heavy-duty vehicles, shipping and cement, according to a new report from BloombergNEF (BNEF).

Neste to receive €88M from EU toward green hydrogen and carbon capture & storage at Porvoo; SHARC

Green Car Congress

The project introduces carbon capture and storage (CCS) and electrolysis solutions that allow decarbonization of production at the refinery. Hydrogen is essential in the production processes of transportation fuels, so the green and blue hydrogen will reduce the carbon intensity of these fuels. BECCS@STHLM, led by Stockholm Exergi.

Harvard team finds large-scale US wind power would cause warming that would take roughly a century to offset

Green Car Congress

All large-scale energy systems have environmental impacts, and the ability to compare the impacts of renewable energy sources is an important step in planning a future without coal or gas power. Wind beats coal by any environmental measure, but that doesn’t mean that its impacts are negligible. Source: Miller and Keith (2018a).

ICCT LCA study finds only battery and hydrogen fuel-cell EVs have potential to be very low-GHG passenger vehicle pathways

Green Car Congress

In addition to its regional and temporal scope, this study is distinct from earlier LCA literature in four key aspects: This study considers the lifetime average carbon intensity of the fuel and electricity mixes, including biofuels and biogas. The results reflect the full life-cycle GHG emissions of battery and fuel-cell EVs.

SRI developing process for co-gasification of methane and coal to produce liquid transportation fuels; negligible water consumption, no CO2

Green Car Congress

Researchers from SRI International (SRI) are developing a methane-and-coal-to-liquids process that consumes negligible amounts of water and does not generate carbon dioxide. In conventional CTL approaches, energy is supplied by burning a portion of the coal feed, which then produces carbon dioxide. Process flow diagram.

GWU team develops cost-effective solar process to produce lime for cement without CO2 emission

Green Car Congress

Conventional thermal decomposition production of lime (left) versus STEP direct solar conversion of calcium carbonate to calcium oxide (right). Surprisingly, this situation is reversed at high temperatures in molten carbonates, which allows the endothermic, electrolytic one pot synthesis, and precipitation of CaO.

IEA: COVID-19 crisis causing the biggest fall in global energy investment in history

Green Car Congress

In the longer-term, a post-crisis legacy of higher debt will present lasting risks to investment. These networks have to be resilient and smart to ward against future shocks but also to accommodate rising shares of wind and solar power. Today’s investment trends are clear warning signs for future electricity security. —Dr Birol.
